Utility of the Montgomery salivary tubes for preventing pharyngocutaneous fistula in total laryngectomy

Abstract

Purpose: To evaluate the prophylactic, protocolized, and standardized use of a Montgomery tube in preventing pharyngocutaneous fistulas after total laryngectomy and neck dissection.

Study design: Retrospective cohort study.

Setting: Tertiary referral centre.

Subject and methods: A Montgomery salivary bypass tube was placed in 44 patients undergoing total laryngectomy and neck dissection, observing the percentage of fistula appearance and the time of start of deglutition. Comparison was made with a group of 28 patients prior to the implantation of the protocol in whom the tube was not used.

Results: There was a statistically significant decrease in the percentage of fistulas and an earlier onset of deglutition in the salivary bypass tube patients compared to those in whom the tube had not been used.

Conclusion: Prophylactic and standardized use of the Montgomery salivary bypass tube in patients undergoing total laryngectomy and neck dissection might decrease the incidence of pharyngocutaneous fistula and improve the course of one that is already established.
