Functional evaluation of mandibular reconstruction with bone free flap. A GETTEC study

peer reviewedObjectives: To assess the functional results of oromandibular reconstruction by free bone flap, in terms of swallowing, speech and esthetics. Materials and methods: A transverse multicenter study included 134 patients reconstructed by free bone flap between 1998 and 2016, with more than 6 months’ follow-up, in 9 centers. A standardized questionnaire collected data on patients and treatment. Study endpoints comprised: weight loss, mouth opening, gastrostomy dependence, type of feeding, and DHI score. The impact of patient baseline characteristics on these functional criteria was explored by uni/multivariate analysis. Results: Ninety of the 134 patients had cancer. Fibula flap was mainly used (80%). 94% of reconstructions were primary successes. 71% of patients had pre- or post-operative radiation therapy. 88% had less than 50% lingual resection. 97% recovered oral feeding. 89% had intelligible speech. 86% judged their esthetic appearance as good/average. 9% had dental prosthetic rehabilitation. Radiation therapy and extensive lingual resection significantly impacted swallowing function (P = 0.04 and P = 0.03, respectively). Radiation therapy and oropharyngeal extension significantly increased gastrostomy dependence (P = 0.04 and P = 0.02, respectively). Conclusion: Oromandibular reconstruction by free bone flap enabled return to oral feeding in most cases. More than 80% of patients were satisfied with their result in terms of speech and esthetics. However, the rate of dental rehabilitation was low and the rate of complications was high. © 202
