Abstract
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.
