Abstract
The purpose of this study was to identify the factors that impact the quality of life (QOL) scores of patients undergoing mandibulectomy.All patients with a diagnosis of an oral cavity neoplasm involving the mandible who underwent a mandibulectomy between January 1, 2000 and December 31, 2015 and completed a University of Washington QOL questionnaire (UW-QOL) were included in the study.Fifty-eight patients fulfilled all inclusion criteria and completed the UW-QOL questionnaire. Forty patients (69%) underwent a segmental mandibulectomy and 18 patients underwent a marginal mandibulectomy. Forty-eight patients (82.7%) had a free flap reconstruction. There was no significant difference in the QOL scores between patients who underwent a marginal or a segmental mandibulectomy. In contrast, patients who underwent symphysial resection reported significantly worse scores in various domains compared to patients with body or ramus segmental mandibulectomy.Patients who underwent a segmental mandibulectomy that included the symphysis had worse outcomes in chewing, recreation, health-related and social QOL domains compared to those whose mandibulectomy did not include the symphysis.
