Hearing loss in peripheral facial palsy after decompression surgery

Area of Science:

• Otolaryngology
• Neurosurgery
• Audiology

Background:

• Facial paralysis, often idiopathic, presents complex diagnostic and treatment challenges.
• Transmastoid decompression surgery is a potential treatment for acute facial paralysis.
• Structures near the facial nerve are vulnerable during transmastoid decompression.

Purpose of the Study:

• To evaluate hearing loss following transmastoid decompression surgery.
• To assess the long-term outcomes of idiopathic facial paralysis treated with this procedure.
• To analyze data from the past 15 years.

Main Methods:

• Retrospective study design.
• Analysis of 33 patient charts undergoing transmastoid facial nerve decompression.
• Assessment of hearing loss and degree of facial paralysis post-surgery.

Main Results:

• A significant percentage (61%) of patients experienced hearing loss post-procedure.
• All patients demonstrated improvement in facial paralysis.
• Findings align with existing literature on surgical outcomes.

Conclusions:

• Transmastoid facial nerve decompression carries a risk of hearing loss, potentially due to proximity to the ossicular chain.
• While hearing impairment is a risk, the procedure effectively improves facial paralysis.
• Informed consent detailing risks, benefits, and indications is essential for patient management.
