Outcomes following pharyngolaryngectomy with fasciocutaneous free flap reconstruction and salivary bypass tube.

Objective: Reconstruction of the pharyngoesophageal defects is one of the most challenging for head and neck surgeons. We evaluated our experience in the hypopharyngeal reconstruction using a fasciocutaneous free flap in conjunction with a Montgomery salivary bypass tube (MSBT).

Methods: Retrospective review. Methods: The charts of 55 patients who had undergone hypopharynx reconstruction using either a radial forearm free flap (RFFF) (24) or an anterolateral thigh (ALT) flap (31) with MSBT were reviewed. There were 40 circumferential and 15 near-circumferential defects. Outcomes analyzed included fistula and stricture rates and swallowing function.

Results: Pharyngocutaneous fistula occurred in 9% of patients (16% using RFFF and 3% using ALT), and strictures occurred in 5% (8% using RFFF and 3% using ALT). Of patients reconstructed with this technique, 95% were able to resume oral alimentation.

Conclusions: The use of fasciocutaneous free flaps in conjunction with the MSBT is a useful tool for pharyngoesophageal reconstruction.
