Summary

Thermal myringotomy offers an effective alternative for middle ear ventilation in patients with eustachian tube dysfunction during hyperbaric oxygen therapy. This procedure shows promising results with fewer complications than traditional tympanostomy tubes.

Area of Science:

  • Otolaryngology
  • Hyperbaric Medicine
  • Middle Ear Physiology

Background:

  • Eustachian tube dysfunction (ETD) is common in patients undergoing hyperbaric oxygen therapy (HBO).
  • Current management with tympanostomy tubes presents risks like prolonged indwelling time and higher complication rates (persistent perforation, otorrhea).

Purpose of the Study:

  • To investigate thermal myringotomy as a safe and effective alternative to tympanostomy tube placement for middle ear ventilation in HBO patients with ETD.
  • To assess the efficacy and complication profile of thermal myringotomy in this specific patient population.

Main Methods:

  • Bilateral thermal myringotomies were performed on 13 patients undergoing HBO who would typically require tympanostomy tubes.
  • Patency rates, need for repeat procedures, persistent perforation, and otorrhea were monitored post-procedure.

Main Results:

  • 96% of myringotomies remained patent at 5 weeks post-procedure, sufficient for most HBO courses.
  • A persistent perforation rate of 15% was observed at 6 months, comparable to tympanostomy tubes in this population.
  • Only one case of otorrhea occurred, which resolved with conservative management.

Conclusions:

  • Thermal myringotomy is an effective technique for middle ear ventilation in HBO patients experiencing ETD.
  • It offers a temporally appropriate solution, potentially avoiding complications associated with longer-term tympanostomy tubes.
