Pharyngocutaneous fistula

Last edited: 4/15/2026

Overview

Pharyngocutaneous fistula is an abnormal communication between the pharynx and the skin, often complicating head and neck surgeries, particularly those involving the pharynx or esophagus. 1

Diagnosis

  • Clinical presentation includes persistent drainage from a surgical wound site 1
  • Imaging studies (e.g., CT, MRI) may help identify the extent and location of the fistula 1
  • Endoscopic evaluation can confirm the presence of a fistula tract 1

    • Management

  • First-line treatment: Surgical repair techniques such as the rhomboid flap have shown high success rates 1
  • Adjunctive management: Conservative management may be necessary in cases where surgical repair fails 1
  • Antibiotics: Not specifically mentioned; use guided by clinical infection signs 1

    • Special Populations

  • Pediatrics: Not addressed in provided abstracts 1
  • Elderly: Not addressed in provided abstracts 1
  • Comorbidities: No specific guidance provided for patients with comorbidities 1

    • Key Recommendations

  • Utilize surgical techniques such as the rhomboid flap for closure of pharyngocutaneous fistulae due to high success rates 1 (Evidence: Strong)
  • Consider conservative management as an adjunct when surgical closure fails 1 (Evidence: Weak)
  • Tailor antibiotic therapy based on clinical signs of infection rather than routine prophylaxis 1 (Evidence: Expert opinion)
