Objective To study concomitant symptoms and disease conditions in sudden deafness. Methods Clinical data of 418 cases of sudden deafness treated in this department from 2000 to 2007 were reviewed. Results Of the 418 cases, 201 were males and 217 were females. Right ear was involved in 184 cases and left ear in 191 cases. Bilateral involvement was seen in 43 cases. The average age was 44.1 years. Tinnitus was reported in 369 cases (88.3%) either before or after hearing loss, of which 64.5% was of low pitch, 27.1% of high pitch and 8.4% of mixed tones. Constant tinnitus was reported in 83% of the cases, and muffled feelings in 33.3% of the cases. Hearing loss was the only complaint in 221 cases (52.9%). Dizziness was reported in 77 cases (18.4%) and vertigo attacks in 120 cases (28%). Hypertension, coronary artery disease and diabetes were found in 19.6% of 418 cases and hyperlipidemia in 54.5% of 211 cases. CT and / or MRI data were available in 147 cases, with positive findings in 18 cases (12.3%): 2 with acoustic neuroma (1.36%); 4 with emphraxis in the basal ganglia, cerebellum, temporal lobe or parietal lobe, and 12 with poor pneumatization of ipsior contralateral mastoid cells. Conclusion In this case series of sudden deafness, low-pitch constant tinnitus was a common complaint. Most of the studied cases presented with simple hearing loss. Vertigo attacks were more common than dizziness in this group of patients. The most common concomitant disorder was hyperlipidemia, especially high triglycerides. Imaging studies are important in managing sudden deafness in ruling out acoustic neuroma and other intracranial diseases.
