Summary

This study on chronic suppurative otitis media in Papua New Guinea found that adults are most affected. The canal-wall-down mastoidectomy is recommended for these patients due to limited follow-up.

Area of Science:

  • Otolaryngology
  • Infectious Diseases

Background:

  • Chronic suppurative otitis media (CSOM) is a prevalent condition, particularly in regions with limited healthcare access.
  • Cholesteatoma, a common complication of CSOM, poses significant risks if left untreated.

Purpose of the Study:

  • To identify common presentations and findings in patients with cholesteatomatous and non-cholesteatomatous CSOM in Papua New Guinea.
  • To determine an optimal surgical management strategy for long-term safety in patients with minimal postoperative follow-up.

Main Methods:

  • A retrospective case series was conducted at Port Moresby General Hospital.
  • Eighty-one patients diagnosed with CSOM, with or without cholesteatoma and complications, were included.
  • The canal-down (modified radical) mastoidectomy with wide meatoplasty was the surgical intervention used.

Main Results:

  • Adults, predominantly males, were more frequently affected (median age 24 years).
  • Otorrhea was the most common presentation; cholesteatoma and granulation were frequent operative findings.
  • Complications included facial paralysis (6% pre-op, 4% post-op), high incidence of 'wet ear', and significant intracranial complications like meningitis and sinus thrombosis, leading to seven deaths (9%).

Conclusions:

  • Late presentations and poor follow-up in Papua New Guinea are linked to health awareness, socioeconomic factors, and healthcare system limitations.
  • The canal-wall-down technique with wide meatoplasty is recommended as a safe, one-time treatment for CSOM with or without cholesteatoma and complications in this population.
