Kathleen Campbell, PhD is a Distinguished Scholar and Professor at Southern Illinois University (SIU) School of Medicine. She served on the American Academy of Audiology Board of Directors, received an American Academy of Audiology Presidential Citation for her work in developing professional practice standards for the American Academy of Audiology, American Speech Language and Hearing Association and the Department of Veteran’s affairs. She also received two Medical Innovators Awards and is a fellow of the American Speech Language and Hearing Association. She authored Essential Audiology for Physicians and edited/authored Pharmacology and Ototoxicity for Audiologists. She has received over 60 grants from National Institutes of Health, US Department of Defense and other agencies for her research in otoprotective agents and is the sole inventor for the protective agent D-methionine patents.
In the future, possibly within 5 or earlier, we may be able to prevent or reduce permanent noise- and drug-induced hearing loss by pharmacologic otoprotective agents. Research suggests these agents may be given before or in some cases even after drug or noise exposure. This presentation will review current research in otoprotective agents for drug- and noise- induced ototoxicity including Dr. Campbell’s own research with D-methionine as an otoprotective agent. This presentation will emphasize oral agents in or approaching FDA approved clinical trials. These agents could change audiologic and otolaryngologic practice. These agents are currently in or approaching clinical trials to prevent cisplatin-induced, aminoglycoside induced and noise induced hearing loss. Dr. Campbell’s own clinical trials with D-methionine, funded by the US Department of Defense and under FDA IND approval, are currently in a Phase 3 clinical trial at Ft. Jackson to prevent noise induced hearing loss and tinnitus at Ft. Jackson. This clinical trial and Dr. Campbell’s research was featured on the front page of the Wall Street Journal in 2015. Further some otoprotective agents for cisplatin induced hearing loss have the potential to reduce other side effects of cancer treatments.

Nasopharyngeal angiofibroma is a benign yet aggressive and destructive vascular lesion of head and neck tumor affecting predominately male between the age group of 12 to 20 also called Juvenile Nasopharyngeal angiofibroma. This retrospective study presents surgically treated patient of juvenile nasopharyngeal angiofibroma. In this study, we discuss major presenting complaints, correlation of radiological and intra operative methods along with the factors affecting the recurrence of juvenile nasopharyngeal angiofibroma. A study of 35 cases of juvenile angiofibroma was conducted from year 2000 to 2010 at Karachi, Pakistan, mostly male adolescent with age ranging from 12 to 20 years. First five cases were operated by trans-palatal approach, while the subsequent 10 cases were operated with lateral rhinotomy, 15 cases with lateral rhinotomy with lip splitting and reaming 4 cases with extended lateral rhinotomy approach within 24 hours of preoperative embolization of internal maxillary artery. One patient age 12 was presumed to be adenoid, later turned out as JNF was approached through endoscope and later removed without embolization. All other patients were preoperatively embolized with the result that intra operative bleeding reduced to an average of 700 ml of blood. Lateral rhinotomy incision was found to be good exposure in wide spread case of tumor while trans-palatine approach proved good result only in cases where the tumor was confined to nasopharynx. Extended lateral rhinotomy approach provides wide exposure for removing the tumor extending into infratemporal fossa and skull base

Time : 11:30-11:55
Ryoji Tokashiki graduated from Tokyo Medical University in 1990. He is a Professor of Tokyo Medical University since 2008. In 2010, he opened his own practice “Shinjyuku Voice Clinic” focusing on voice disorders. He performed over 200 voice surgeries for vocal fold paralysis (UVFP), spasmodic dysphonia and achieving promising outcome. He also performed over 500 office surgeries annually for vocal fold lesions such as polyp, nodule, cyst and injection laryngoplasty. His practice also treats a lot of functional voice disorder patients including stuttering. At present, he is interested in analyzing brain activity when phonation using functional MRI.
Objective: In this presentation, I will talk about the passive movement of paralyzed arytenoid (Jostle’s sign) in UVFP (unilateral vocal fold paralysis) and think about necessity of arytenoid adduction (AA).
rnrnIntroduction: We have examined the movement of paralyzed arytenoid of UVFP by three-dimensional computed tomography (3DCT). We detected the cricoid and arytenoid cartilage and compared these status when inspiration and phonation. In all cases, even in light cases, the paralyzed arytenoids were passively displaced cranially which we consider the most important etiology of UVFP. There are some surgical procedures for UVFP such as injection laryngoplasty, type 1 thyroplasty, AA or others. Each procedure is useful but we think the voice acquired by AA is better than others because only AA can resolve this passive movement. String needs tension to produce good sound and two support points, the anterior commissure and adducted vocal process, should be fixed to obtain tension. The meaning of AA is not resolve wide posterior glottal chink, but reproduces two support points to obtain good vocal fold tension.
rnrnMethods: Fenestration approach for arytenoid adduction –what is deferent from other AA? - AA is performed through a fenestration of the thyroid ala. Usually additional type I thyroplasty is needed to restore volume of the thyro-arytenoid muscle. Key of this surgery is no release of the cricothyroid joint and the cricoarytenoid joint. If one or both of these joints is opened, the vocal fold sometimes loses its tension and patients voice wouldn’t improved. As the surgery is performed local anesthesia, surgeons can check patient’s voice during surgery result in no risk of voice worsening.
rnrnResults: Over 100 cases of UVFP were treated by this procedure since 2007. There were no patients whose voice didn’t improve and most of all patients achieved an MPT of over 10s and an MFR of fewer than 200ml/s. Only one patient needed tracheotomy because of laryngeal edema after surgery.
rnrnConclusions: Arytenoid adduction reproduces natural adduction and resolves the passive movement giving the vocal fold “tension”.rn

Allergic rhino sinusitis is common condition seen in day to day ENT practice. Especially in urban area, people are facing significant nasal symptoms, may be due to more exposure to pollutants and chemicals. Although allergic reaction is hyper immune response of our body to any particular allergen/s and well controlled by medical treatment in form of anti-allergic and steroidal nasal spray with or without oral antihistamines and mast cell stabilizers but there is stage where even use of these medicines do not give significant improvement in patient symptoms of persistent nasal obstruction, decrease or loss of sense of smell. Then the role of surgery comes in scene. Studies done in past found that there is up to 61% reduction of medicine requirement for nasal allergy and asthma postoperatively. Although allergic rhino sinusitis is well controlled by medicine but in chronic allergic rhino-sinusitis and its complication, surgery has a significant role.

Allergic rhinitis represents a major cause of morbidity that includes interference with usual daily activities and impairment of sleep quality. The majority of patients respond adequately to pharmacotherapy, provided that it is taken properly and regularly. Nevertheless, a substantial proportion of patients report inadequate relief of symptoms despite treatment with intranasal corticosteroids and oral or topical antihistamines. Immunotherapy, both subcutaneous and sublingual, is an effective treatment for adults and children with severe allergic rhinitis that does not respond to conventional pharmacotherapy and allergen avoidance measures. It is also reasonable to offer allergen immunotherapy to those unable to tolerate pharmacotherapy. Selection of patients for immunotherapy requires accurate identification of an underlying allergic trigger through a combination of clinical history and skin and/or blood tests for allergen specific IgE. The efficacy of immunotherapy depends on correct patient selection, the type of allergen and the product chosen for treatment. The benefit of immunotherapy for AR triggered by perennial allergens, particularly HDM, is less well established than with seasonal allergens. The available data also suggests that immunotherapy may offer long-term benefits after its discontinuation, particularly where treatment has been continuously administered for several years.

Respiratory disorders are a big issue that affects around 60% of the population all over the world. It varies from simple snoring up to severe stridor which appears mainly during sleep. The cause of all respiratory disorders depends on obstruction, vibration or both. We can also find respiratory disorders in some rare cases like Obesity Hypoventilation Syndrome or Multisystem Disease. The respiratory events start with simple snoring without symptoms of dyspnea or hypopnea. It may extend to arousals due to respiratory efforts (RERAs Syndrome). With more and more distress, the hypopnea (decrease in Oxygen) appears till complete apnea occurs with awakened stridor. The most common sequence of events in sleep respiratory disorders can be summarized into the following; simple snoring which leads to the increase in upper airway resistance and finally ending in a group of syndromes like OSAS (Apnea, Hypopnea, RERAs).In another sequence, snoring leads to Uvular Oedema which feels like morning Obstructive Sleep Hypopnea Apnea Syndrome (Ob-SHAS). This leads to increase in Arterial Hypertension which causes daytime sleepiness. There are a lot of complications in OSAS which may be local complications in mouse, nose and chest or CVS complications like Erythema or Hypertension or psychological problems like dizziness or loss of consciousness or daytime sleepiness. One of the most common problems is how to exactly detect the size and site of the obstruction of air flow. There are several methods like full history of the patient and the partner, full clinical examination, full radiological examination or fiber-optic endoscopic examination. The treatment is either medical or surgical according to the case.

Brain is protected from thermal damage by a so-called radiator system: brain cooling system. As brain gets hotter, the veins of this radiator system bring in cool blood from the evaporating surfaces of skin and craniofacial cavities. Nasal cavity, paranasal sinuses, tympanic cavity and certain parts of head skin are the major components of this system. The cooling occurs through evaporation of mucus or sweat, and the transfer of the cool venous blood to the brain. Therefore washing or wetting these surfaces of the head (face, mouth, nose, scalp, nape and ears) a number of times helps the brain to remain cool throughout the day. In hot climates as in Africa, craniofacial features such as thick everted lips, broader nasal cavity and bigger paranasal sinuses provide more evaporating surfaces for an effective brain cooling. These geographic variations are due to direct environmental effects which, over many generations, became inherited. Epigenetic inheritance system is a genetic regulatory mechanism that allows humans to maintain extraordinarily stable patterns of gene expression over many generations. It enables organisms to acquire and transmit different phenotypes to the next generation. In this system, heritable changes occur in gene expression that are not encoded in the DNA sequence itself in the germ cells (oocytes). Epigenetic modifications of DNA include covalent modifications of bases in the DNA and of amino acid residues in the histones. But inheritance of adaptive changes is limited to embryonic neural crest derivatives such as craniofacial tissues and melanocytes, and species-to-species evolution seems unlikely.
Julien Wen Hsieh graduated from University of Geneva Medical School (CH) where he worked on human olfaction following nasal surgery and the control of genome expression in yeast cells. He carried out an Ear, Nose and Throat (ENT) residency at Luxembourg Hospital Center in Luxembourg. In 2014, he won the "Junior Scientific Excellence Prize" for the development of a Smell and Taste Clinic in Luxembourg to treat chemosensory disorders and promote research in this field. He joined the Vosshall Lab at The Rockefeller University in January 2014 as an Instructor in Clinical Investigation. He is working with Andreas Keller in designing novel smell tests that will be useful to diagnose olfactory dysfunction in clinical settings around the world.
Background: Smell dysfunction severely affects human health. Olfactory tests are available; however, they have two shortcomings: (a) the testing scores depend on familiarity with the odors used in the test, and (b) they rely on the detection of a single type of molecules and people are frequently insensitive to single types of molecules, due to differences in genetic background, which are unrelated to health. This leads to misdiagnosis. To address these issues, we developed a set of olfactory tests designed to be useful in all genetic and cultural populations: The General Olfactory Threshold (GOT) and the Olfactory Resolution (OR) tests.<br>
Objectives: To investigate whether (a) the GOT test is reliable and can discriminate between subjects with low sensitivity to phenyl ethyl alcohol and anosmic subjects, and whether (b) the OR test is reproducible and measures a different aspects of olfactory perception than GOT test.<br>
Methods: The design was a test-retest reliability study. The primary outcome measure was the testing score of a butanol threshold, phenyl ethyl alcohol threshold, GOT 1, GOT 2, OR 1, and OR 2 tests. Results: A total of 75 subjects were recruited (mean age: 44.06 ± 16.77; range: 21 to 72). Regarding the GOT tests, we found that the single measure of intra class correlation coefficient was 0.43 and 0.63 for GOT 1 and GOT 2, respectively. The inter-individual variability of the GOT score was reduced compared to the olfactory threshold test (Olfactory threshold versus GOT 1: F (74, 74) = 2,982 P<0.0001; Olfactory threshold versus GOT 2: F(74,73)=2,579 P<0.0001 ). The only anosmic subject could be detected with the GOT test, but not with the olfactory threshold test. The Intra-class Correlation Coefficient of OR 1 and OR 2 was 0.74 and 0.65, respectively. We showed that the Pearson’s correlation between threshold and resolution tests is small (r=0.164-0.365), whereas the correlation between tests of the same kind is greater, especially if they were the novel smell tests (GOT 1 vs. GOT 2: r=0.62; OR 1 vs. OR 2: r=0.58).<>
Conclusion: We developed a reliable method to quantify the resolution and the general threshold of the olfactory system. We showed that this method is able to distinguish between healthy subjects with low sensitivity to phenyl-ethyl alcohol and subjects with a reduced general olfactory sensitivity. Both tests measured different aspects of the olfactory system.

Introduction: Internal nasal valve collapse is a troublesome that the Otolaryngology doctors faces in many patients suffering from inadequate nasal breathing. There are two main suggested reasons for inadequate nasal breathing at the internal nasal valve region; collapsing alar cartilage and narrow nasal angle. While most of the new literature emphasizes the spreader graft technique, I believe that flaring technique still plays an important role in management this challenging quest.
Aim: The aim of the present study is to re-evaluate the role of combining alar flare technique to spreader graft in management of internal nasal valve collapse.
Patients & Methods: 56 patients were included in the present study that underwent different surgical techniques for management of internal nasal valve collapse. None of the patients had undergone any nasal surgical repair procedure to his or her condition before. Spreader graft technique have been used alone in 10 patients, while combined alar flare with spreader graft technique was used in 46 patients through an open rhinoplasty approach. The time of surgical procedure, post-operative healing time, subjective scoring of nasal airway breathing before and after surgery and the degree of nasal dryness were recorded and compared between the two surgical groups. The post-operative evaluation period ranged from 3 to 5 years.
Results: In the first group of patients who underwent spreader graft technique alone all patients have reported an initial improvement in nasal airway breathing but only 80% of them have sustained these results after 4 years. In the second group of patients who underwent a combined alar flare with spreader graft technique, 95.7% of patients have sustained these satisfactory results after 5 years of surgical procedure.
Conclusion: The combined alar flare with spreader graft technique still provides better results than any of the two surgical techniques alone.

Aim: Our study aimed to determine the effect of marriage and sexual activity as risk factors on allergic rhinitis and to figure out degree of impact of consanguinity in the Saudi population on allergic rhinitis.
Methods: The study design was a cross-sectional study. The study was conducted at the outpatient ENT clinic of King Faisal University polyclinic centre at the period from October 2015 to February 2016. A random of 60 patients of age group 20-55 years old including both sexes. The inclusive criteria were patients experienced symptoms related to out- door, indoor allergic rhinitis in the past 12 months. All of them were married and subjected to a questionnaire. It included 21 questions assessing symptoms of allergic rhinitis to verify the diagnosis, and its frequency and severity. It also included the marital details and patterns of consanguinity. The result was 7 female patients (out of 24=29%) and 4 male ones (out of 25=16%) admitted experience of post coital exacerbation of allergic rhinitis attacks. In discussion the two previous studies could not find any association between AR prevalence and marriage. Marriage exerted a protective effect on AR in another study. In contrast, unhappy marriage or dissatisfied marriage can put people under stress and health problems.
Results: Human seminal plasma allergy, in women, is usually caused by sensitization to proteins present in the seminal fluid, leading to immediate hypersensitivity manifestations during or soon after coitus. Four patients had experienced post-coital exacerbation of asthma and allergic rhinitis in a case report. Sexual intercourse can precipitate sexercise-induced asthma or honeymoon rhinitis due to emotional excitement or autonomic over activity.
Conclusion: Marriage and sexual activity are risk factors for allergic rhinitis as 18% of our study experienced post coital exacerbation of allergic rhinitis attacks.

We tend to consider taste to be a minor sense, although gustatory perception is highly refined. Its physiology is poorly understood and the little is known about the symptoms of pathological conditions affecting taste. Taste is essentially an oral sense, and it is now widely accepted that we can perceive seven different basic tastes: sweet, salty, bitter, sour, umami, astringent and metallic. Taste is also linked to olfaction (the sense of smell) and salivation. Patients experiencing taste problems should undergo a detailed interview with their doctor, with the aim of identifying the cause of the problem. Buccal, ear-nose-and throat and neurological examinations should be carried out and chemical or electrical stimulation tests can also be very useful. Taste problems may have many different causes. They affect quality of life, reduce appetite and constitute a risk factor for under-nutrition. These conditions are difficult to treat, requiring elimination of the cause, the use of flavor enhancers or a change in diet according to the advice of a dietician. Any associated under-nutrition must be dealt with. This article focuses on post-traumatic dysguesia and its management in affected workers.

Background: The intranasal steroids remain the most effective treatment as all major symptoms of allergic rhinitis are effectively attenuated. However, addition of decongestant increases the response obtained along with intranasal steroids. The data on effect of addition of Oxymetazoline to fluticasone is limited. Hence, this study was done to compare the efficacy of fluticasone combined with oxymetazoline and fluticasone alone for a 4-week treatment course of allergic rhinitis.
Methodology: In this randomized, open, parallel study, out of 123 patients randomly assigned to receive fluticasone with oxymetazoline (Group 1) or fluticasone alone (Group 2), 91 patients completed the entire 4 weeks of study. The primary outcome measure was mean change of the daytime nasal symptom score (PDTS) and secondary outcome measure was mean change of nighttime nasal symptom score (PNTS) and composite symptom score (PCS).
Results: The change in total daytime nasal symptom, composite symptom, night time nasal symptom score was significantly (p<0.05) greater in Group 1 as compared to Group 2. Sub-group analysis showed a significantly (p<0.05) greater improvement in congestion score from 2nd week onwards in Group 1.
Conclusion: Oxymetazoline combined with fluticasone was effective in reducing daytime, night time, and composite symptom score as compared to fluticasone alone.

Recently, a new acoustic device, the so-called Sophono Alpha system (SAS), has been introduced into clinical practice. This is a boneconduction system, implanted transcutaneously, devised for restoring conductive or mixed hearing loss with bone conduction thresholds better than or equal to 45dB. It consists of a behind-the-ear external digital audio processor and a subcutaneous magnetic implant, screwed to the skull. To our knowledge, no investigation has been reported regarding its use in patients submitted to subtotal petrosectomy (SP). This surgical technique induces a postoperative conductive hearing loss up to 50 or 60 dB. SAS may be an optimal alternative to conventional bone conductive hearing aids, in order to restore adequate hearing. The aim of this study was to assess SAS hearing aids in 10 patients suffering from recurrent chronic middle ear disease who underwent subtotal petrosectomy. Presence of mixed hearing loss with bone conduction thresholds better than or equal to 45dB was present in each patient. Audiometric tests were performed before and after Sophono implantation and using a conventional bone conduction hearing aid (hearing glasses). Speech audiometry data (speech recognition threshold and word recognition score) were also performed. Speech recognition threshold in dB and percentage of word recognition score at 65dB were subsequently calculated. After implantation and activation of the Sophono Alpha system audiological data showed an average air conduction value of 42.1 dB. By comparing this data with the values of air conduction following subtotal petrosectomy, an average acoustic improvement of 29.7 dB could be calculated. Results in terms of hearing have been compared with those obtained using conventional hearing aids. The hearing results showed significant better outcomes of Sophono Alpha system vs. conventional bone conduction aid. Information about general, social and physical patient benefits after SAS implantation was carefully investigated using the validated Glasgow Benefit Inventory.

Title: Rate of metastasis to sub-mandibular gland in early stage oral cavity SCC multi-centric study
Time : 16:15-1:35
Mohammed Alshahrani has completed his MBBS at the age of 24 years from King Saud University and currently an Otolaryngology resident in Saudi Arabia. He has published 2 papers and has many ongoing researches focusing on Otolaryngology.
Introduction: Supraomohyoid neck dissection considered as a part of the management in oral cavity cancer mainly, by dissecting the lymph node in level I-III including the submandibular gland. This will let the patient to have xerostomia post-operatively and it will be worse if the patient received radiotherapy post-operatively. For this reason, we conducted this study to find out the incidence and pattern of metastasis to submandibular gland in oral cavity cancer. This will answer our question if is it safe to preserve it intraoperatively to minimize the risk to have xerostomia later on.
Methodology: Multicenteric retrospective review for all the patients who diagnosed with early stage oral cavity SCC and underwent surgical resection of the primary tumor with neck dissection involving the submandibular gland in King Fahad Medical City-Riyadh- KSA and King Abdul-Aziz Medical City-Jeddah-KSA between 2008 and 2016.
Result: 41 patients were included in our study and 68% of them diagnosed with moderately differentiate SCC. None of our patient reported to have metastasis to the submandibular gland.
Conclusion: Metastases to the submandibular gland itself are extremely rare. Removal of the lymph nodes in sublevel IB seems to be feasible without removal of the submandibular gland itself. This will prevent the patient to have xerostomia.
Rhinitis is one of the most common occupational diseases. Since it causes little disability, it is often neglected by affected individuals. However, it is often the preliminary manifestation of a respiratory disorder that could lead to physical complications and socio-economic disability. The potential causative agents of rhinitis are both numerous and diverse. Respiratory disorders that initially manifest as rhinitis may progress to asthma with continued exposure. Prevention of occupational rhinitis depends upon reducing exposure to allergens and irritants. When rhinitis becomes apparent, removal of the causative agent is essential to stop progression to asthma.
