Oromandibular reconstruction with vascularized free flaps: a review of 50 cases.

Abstract

Fifty cases of oromandibular reconstruction using vascularized free flaps to evaluate functional parameters of results were evaluated. There were 23 iliac crest flaps, 17 fibula flaps, 30 ulnar forearm flaps, and 3 radial forearm flaps with bone. Thirteen female and 37 male patients comprised the study, with a mean age of 57.66 years. Squamous-cell carcinoma (SCC) constituted 86% of cases, of which 60% were T4 lesions and 13.9% were recurrent. Anterolateral mandibular defects constituted 48.7%, and the mean bone gap was 8.13 cm. Functional evaluation was based on the University of Washington Questionnaire (UWQ) through phone calls and personal communication. The mean hospital stay was 12.42 days. The external carotid (75%) and facial (18.3%) were the main recipient arteries. The internal jugular (47.05%) was the main recipient vein. Overall flap survival was 95.9%. Three flaps were lost due to unsalvageable venous thrombosis. Major local complications such as partial flap loss, hematoma, and orocervical fistula constituted 10% of cases. Speech was classified as "excellent" and "good" in 43.3% of cases. Swallowing was identified as "excellent" and "good" in 53.3% of cases. Cosmetic acceptance was rated "good" in 63.3% of cases. Vascularized free flap reconstruction of oromandibular defects provides excellent functional and aesthetic results. The majority of patients are able to tolerate a regular diet. Intelligible speech and acceptable appearance are restored, providing patient satisfaction.
