Imaging of otosclerosis

Area of Science:

• Otolaryngology
• Radiology
• Medical Imaging

Background:

• Otosclerosis is a significant cause of hearing loss and a common otolaryngology pathology.
• CT imaging is vital for diagnosis and therapy planning, though often overlooked in routine diagnostics.
• Subtle imaging findings necessitate targeted searches and optimal imaging techniques for detection.

Purpose of the Study:

• To review the imaging aspects of otosclerosis.
• To provide guidance on optimal imaging techniques for otosclerosis.
• To discuss characteristic imaging signs, differential diagnoses, and post-surgical findings.

Main Methods:

• Selective literature search of PubMed without time restrictions.
• Incorporation of extensive clinical experience from authors.

Main Results:

• CT imaging is the primary radiological diagnostic method for otosclerosis.
• Characteristic imaging signs, differential diagnoses, and post-stapedoplasty findings are detailed.
• Radiology plays a key role in diagnosing retrofenestral otosclerosis.

Conclusions:

• Accurate diagnosis of otosclerosis is achievable with optimal imaging techniques and radiologist expertise.
• Radiology is essential for identifying complications after stapedoplasty, guiding reoperation decisions.
• Imaging provides valuable information for managing hearing loss and cochlear implant candidacy.
