The occurrence of pharyngocutaneous fistula (PCF) after total salvage laryngectomy following radiotherapy
as primary treatment is quite common. In most cases, pharyngocutaneous fistula can heal spontaneously
with conservative measures. Here, we are reporting a 69-year-old male with a residual carcinoma of the
larynx following failed radiotherapy as primary treatment whose later underwent a salvage total
laryngectomy. Post-operatively, it was complicated by the formation of pharyngocutaneous fistula which
was failed to heal with conservative measures and few attempts of surgical repair. The fistula later healed
with the application of Montgomery Salivarybypass tube after 3 weeks. The application of the salivary
bypass tube should be considered and used to promote healing in persistent pharyngocutaneous fistula
especially in a post radiotherapy patient.
