Practice Patterns in Asymmetric Sensorineural Hearing Loss: Survey Data.

Area of Science:

• Otolaryngology
• Audiology
• Medical Imaging

Background:

• Asymmetric sensorineural hearing loss (ASNHL) management lacks standardized screening protocols.
• Existing guidelines offer varied thresholds for imaging, leading to inconsistent practices.
• This study investigates current otolaryngologist practices for ASNHL patient imaging.

Purpose of the Study:

• To compare the imaging protocols used by otolaryngologists for patients with ASNHL.
• To identify variations in practice patterns among different otolaryngologist subspecialties.
• To highlight the need for evidence-based guidelines in ASNHL management.

Main Methods:

• A web-based survey was distributed to otolaryngology faculty at academic medical centers.
• The survey included demographic questions, general practice patterns, and simulated patient cases.
• Data were collected from 88 respondents out of 468 distributed surveys (18.8% response rate).

Main Results:

• The majority defined ASNHL as >30 dB asymmetry at one frequency, or >20 dB at two continuous frequencies, or >10 dB at three contiguous frequencies.
• General otolaryngologists were more inclined to rely on serial audiograms alone.
• Otology/neurotology specialists showed a higher tendency to order imaging studies.

Conclusions:

• Significant variability exists among providers in managing ASNHL.
• There is a clear need for evidence-based guidelines to standardize imaging practices for ASNHL.
• Standardized guidelines would improve patient care and diagnostic consistency.
