... multicenter analysis of SSHL. We were used spearman correlation matrix test for correlations between all variables. One hundred twelve patients with SSHL were evaluated. Results: A total of 112 patients (62 males, 50 females) ranging in age from 17 to 70 years (average male 40.21 ± 14.04, average female 40.26 ± 11.16) were included. Fourteen of these had AOM. The majority of patients had moderate hearing loss. Flat and down-sloping types of audiogram were also observed (P<0.05). There was a positive relationship between SSHL and AOM, SOM, cardiac pathology as hypertension. No significance was established in terms of age or sex (p>0.05). Otoscopic examination was consistent with AOM. SSHL occurred as mixed-type hearing loss. Tympanometry was observed as type A. Conclusion: In the treatment and follow-up periods, AOM patients should be checked and treated for the presence (if any) of early hearing loss. Otol a ry n g o lo gy: O p e n A c ce ss
