Reconstruction of circumferential pharyngolaryngectomy using a ‘horseshoe-shaped’ pectoralis major myocutaneous flap

Abstract

Eighteen patients underwent a circumferential pharyngolaryngectomy reconstruction post pharyngolaryngectomy. All tumours showed pharyngo-oesophageal junction invasion or circular involvement of the hypopharynx, requiring total, circumferential pharyngolaryngectomy. A pectoralis major myocutaneous flap was directly sutured to the pre-vertebral fascia. A Montgomery salivary bypass tube was introduced into the oesophagus, and a nasogastric tube was placed within it. No post-operative complications occurred for 14 patients and only minor ones for the other four. Average post-operative stay was 12 days. For 15 patients, feeding returned to normal throughout the follow-up period. No fistulae were noted and neopharyngeal stenosis occurred in three patients (16 per cent). Thirteen had complete resection with normal margins. Thirteen were still alive after one to three years of follow up. The local recurrence rate was 16 per cent. The use of a pectoralis major myocutaneous flap with Spriano's technique provides a simple, reliable method for circumferential hypopharyngeal resection. It has been applied to a wide range of patients, especially elderly ones and those with poor general status, as well as to cases in which widespread involvement was detected during surgery.
