Circumferential pharyngeal reconstruction: history, critical analysis of techniques, and current therapeutic...

Reconstruction of circumferential pharyngeal defects following total pharyngolaryngectomy presents major challenges with respect to surgical morbidity and restoration of functional deficits, which are often made more demanding by the increasing trend to utilize primary chemoradiation protocols with surgery reserved for salvage cases. The present review evaluates the reconstructive techniques described in the literature, including historical techniques as well as more recent innovative methods. Each technique is critically appraised with particular reference to postoperative morbidity and functional rehabilitation. Treatment recommendations are made based on the available evidence.
