Objectives: To present a technique for reconstruction of the vertical partial laryngectomy defect using a vascularized carrier consisting of a temporoparietal free flap, cartilage graft, and buccal mucosal graft; to evaluate the oncologic outcomes with respect to locoregional control and overall survival; and to provide an assessment of patient quality of life and functional outcomes.
Design: Retrospective medical record review and prospective cross-sectional analysis of functional outcomes.
Setting: Princess Margaret Hospital-University Health Network and the Odette Cancer Centre-Sunnybrook Health Sciences Centre.
Methods: We collected data on patient demographic characteristics, tumor staging, initial treatment, recurrence, management, and follow-up. Prospectively, a cross-sectional study was performed using the European Organization for Research and Treatment of Cancer Quality of Life of Cancer Patients Questionnaire C30 and HN35 module and voice and swallowing results using the Voice Handicap Index and Swallowing Quality of Life index.
Main outcome measures: Local recurrence-free survival, cause-specific survival, and overall survival.
Results: Forty men met inclusion criteria (median age, 65.0 years). Local recurrence-free survival was 84% at 3 years and 75% at 5 years. Cause-specific survival was 88% at 3 years and 78% at 5 years. Thirty-eight patients were successfully decannulated; all patients tolerated oral intake after the surgical procedure. The C30 and HN35 symptomatic results were comparable with patients with standardized stages I and II head and neck tumors. The Voice Handicap Index results were comparable with patients with functional dysphonia. Patients' swallowing was in the normal range.
Conclusions: Patients receiving vertical partial laryngectomy with temporoparietal free flap reconstruction for recurrent glottic carcinoma following radiation treatment failure have high rates of locoregional control. The use of the temporoparietal free flap in this patient population produces high-quality voice results and normal swallowing and has no major effect on quality of life.
