Otosclerosis and Fitness to Fly

Area of Science:

• Otolaryngology
• Aerospace Medicine
• Audiology

Background:

• Otosclerosis diagnosis in aircrew raises concerns about flight fitness.
• A retrospective study was conducted to analyze otosclerosis cases in aviators.

Purpose of the Study:

• To describe a case series of otosclerosis in an aircrew population.
• To discuss flight waiver decisions for aircrew with otosclerosis.

Main Methods:

• Retrospective examination of medical files for 27 aircrew members referred for otosclerosis.
• Evaluation of auditory and balance status, postoperative CT scans, and operative reports.

Main Results:

• Out of 27 aircrew, only 3 did not obtain a flight fitness waiver.
• 12 of 14 surgically treated patients with waivers had no flight restrictions.
• 7 non-operated patients were fit to fly without a waiver, and 3 obtained one.

Conclusions:

• Fitness for flight is determined by auditory and balance status, and surgical outcomes.
• Stapes surgery can allow safe return to aviation activities under specific conditions.
• Vestibulocochlear assessment is crucial for determining flight eligibility post-otosclerosis treatment.
