Background:
To know the prevalence of sensorineural hearing loss among chronic suppurative otitis media patients
To study the correlation between duration and clinical findings of CSOM with the degree of hearing loss.
Materials and Methods
Hospital based cross sectional study of patients aged between 10 to 45years with unilateral chronic suppurative otitis media attending Tirumala Super speciality Hospital, Kadapa from December 2015 to November 2017 with sample size of 100 cases were taken.
Results: Out of the 100 cases, 10 patients were having sensorineural hearing loss. Thus the percentage is 10%. Out of the 10 cases of sensorineural hearing loss, no cases with sensorineural hearing loss between 10-15yr and 16-20yr age group. 2 were between in the age group of 26-30yr, 31-35yr and 36-40yr age group and 4 patients were in the age group of 41-45yr. Out of 100 patients 52 were males and 48 were females. Out of 10 patients with sensorineural hearing loss 6 were males and 4 were females. The duration of ear discharge ranged from 3 months to more than 15 years. Among the 100 patients studied 64 had ear discharge from 3months to 5yr. 16 had ear discharge from 6-10yr, 11 had ear discharge from 11-15yr and 9 had ear discharge of more than 15years.
Conclusion: Our study shows presence of significant (10%) sensorineural hearing loss in patients with chronic suppurative otitis media.
Duration of ear discharge correlates well with sensorineural hearing loss.
No significant correlation between sex and sensorineural hearing loss.
