OBJECTIVE : To determine the clinical characteristics and treatment results of benign and malignant tumors of the hard palate in our hospital.
METHODS : A total of 25 patients who underwent surgical treatment for hard palate tumors between 2008 and 2018 were included in this study. Their demographic characteristics, smoking status, alcohol consumption, symptoms, duration of symptoms, size and localization of hard palate tumor, status of mucosal surface, radiologic examinations, surgery, reconstruction method, histopathologic results, treatment outcomes, oral intake start time, adjuvant treatment, postoperative complications, and recurrence were reviewed.
RESULTS : Of the 25 patients with hard palate tumors, 15 (60.0%) had benign tumors and 10 (40.0%) had malignant tumors. Both benign and malignant tumors of the hard palate occurred more frequently in females than in the males. The most common symptom of hard palate tumor was palate mass. The most common benign tumor was pleomorphic adenoma (n = 13). The most common malignant tumors were squamous cell carcinoma and carcinoma ex pleomorphic adenoma (n = 3 for each). All patients were operated via transoral approach without external incision. We did not experience any recurrence in this study. The oral intake start time was late in malignant hard palate tumors (p < 0.05).
CONCLUSIONS : The comparison of clinical features of benign and malignant hard palate tumors showed a statistical significance only for oral intake start time. Transoral surgical removal with clear margin is a safe and effective procedure for benign and malignant hard palate tumors.
