Bullous myringitis and sensorineural hearing loss

Area of Science:

• Otolaryngology
• Audiology
• Infectious Diseases

Background:

• Bullous myringitis is an acute infection of the tympanic membrane.
• The auditory consequences of bullous myringitis, particularly sensorineural hearing loss, are not well-established.

Purpose of the Study:

• To investigate the incidence and characteristics of sensorineural hearing loss in patients diagnosed with bullous myringitis.
• To determine the prevalence of different types of hearing loss associated with bullous myringitis.

Main Methods:

• A prospective study involving 15 patients (21 ears) diagnosed with bullous myringitis over 24 months.
• Pure tone and speech audiometry were conducted early in the clinical course for all affected ears.

Main Results:

• Sensorineural hearing loss was identified in 7 ears (33%).
• Mixed hearing loss (conductive and sensorineural components) was observed in 7 ears (33%).
• No purely conductive hearing losses were found; hearing recovery was complete in 8 of 14 ears with follow-up.

Conclusions:

• Sensorineural hearing loss is a common finding in bullous myringitis.
• The study underscores the importance of audiological assessment in bullous myringitis to detect and manage hearing deficits.
• Further research is warranted to understand the pathophysiology and long-term implications of hearing loss in this condition.
