Summary
Vertigo presence in idiopathic sudden sensorineural hearing loss (SSNHL) patients did not directly impact hearing recovery. However, vertigo interacted with initial hearing levels to influence SSNHL outcomes.
Area of Science:
- Otolaryngology
- Neurology
Background:
- Idiopathic sudden sensorineural hearing loss (SSNHL) is a condition with variable prognoses.
- The role of vertigo as a prognostic indicator in SSNHL is not well-established.
Purpose of the Study:
- To compare outcomes in SSNHL patients with and without vertigo.
- To determine if vertigo is a valid prognostic factor for SSNHL recovery.
Main Methods:
- A comparative study of 183 SSNHL patients, divided into those with vertigo (n=31) and without (n=152).
- Statistical analysis included t-tests and multiple regression to assess prognostic factors and interactions.
Main Results:
- Patients with vertigo had significantly lower initial hearing levels and shorter treatment onset times.
- Vertigo alone did not predict hearing improvement, but its interaction with initial hearing level significantly affected outcomes.
Conclusions:
- Clinical features of vertigo in SSNHL patients do not directly correlate with hearing improvement.
- Vertigo influences SSNHL prognosis indirectly through its interaction with initial hearing levels.
