Abstract

Objectives: The aims of our study were to evaluate the clinical features, and early results of treatment of submandibular tumor at National Cancer Hospital. Patients and methods: A retrospective and prospective descriptive study in 74 patients with sunmandiblar tumor were treated in K hospital from 01/2016 to 6/2022. Results: benign/malignant ratio is 1,31, female/male ratio is 1,05/1, painless mass at gland is the most common symptom. Tumor size 2-4 cm 72,6%, right/left is 1,1/1, hypoechoic 89%. With benign tumors, the commonest histopathology is pleomorphic adenoma, Among the malignant tumors, adenoid cystic carcinoma was the commonest tumor 34,37%, followed by mucoepidermoid carcinoma 25%. With benign tumors, surgery removed the tumor 35,7%, removed the whole gland+tumor 64,3%, 96,9% of cancer  underwent surgery to remove the entire gland, 53,1% lymph node dissection. Common complications are early paresis of the marginal branch of the facial nerve 10,8%, recover after 6 months, lingual nerve paresis, hematoma are uncommon. Conclusions: Histopathology of submandibular tumor is diversity. Clinical and subclinical features can guide diagnosis and treatment prognosis. Surgery is the most important treatment method, with high efficiency and fewer complications.
