Reconstruction of subtotal pharyngolaryngectomy using a fasciocutaneous free flap with cartilage graft: A case series of 17 patients.

Abstract

Subcricoid-hemilaryngopharyngectomy (SCHLP) with a reconstruction using a fasciocutaneous free flap armed with cartilage graft (FFACG) aims to avoid permanent tracheostomy while still maintaining the laryngopharyngeal functions. The purpose of this study is to report the outcome of this surgical approach. Retrospective study including 17 men operated between 2001 and 2019. Specific survival rate included death caused by cancer or SCHLP complications. Complications, functional and oncological outcomes were evaluated retrospectively. There were no locoregional recurrences. One patient died due to inhalation pneumonia 3 years after surgery. Tracheostomy was closed in 13 patients (76.5%). Mean decannulation time was at six [1-14] months after surgery. SCHPL with FFACG could avoid total pharyngolaryngectomy with good oncologic results. However, tracheotomy is extended and deglutition recovery is long with high risk of aspirations. These complications justify that such surgery should be realized only on selected patients by experienced surgical teams. Expertise of the surgical team is critical.
