Objectives: To assess the frequency of anterior pharyngeal pouch formation after total laryngectomy, and to discuss the causes and consequences of anterior pharyngeal pouch formation.

Study design: A prospective, observational study of 43 patients undergoing total laryngectomy.

Methods: Data collected included laryngeal defect closure type, tumour staging and demographic information. A barium swallow was performed on day 7-14 after surgery to assess for anterior pharyngeal pouch formation and fistula formation.

Results: The incidence of anterior pharyngeal pouch formation was 47 per cent. Patients who did not have an anterior pharyngeal pouch on swallow imaging assessment were less likely to develop a pharyngo-cutaneous fistula. There was no statistically significant association between laryngeal defect closure type and anterior pharyngeal pouch formation.

Conclusion: The anterior pharyngeal pouch is a dynamic phenomenon best investigated with a fluoroscopic swallow imaging study. Its causes are multi-factorial. Absence of an anterior pharyngeal pouch appears to confer protection against pharyngo-cutaneous fistula formation, hastening commencement of adjuvant therapy and an oral diet.
