TYPE AND DEGREE OF HEARING LOSS IN PATIENTS WITH TINNITUS
Background &Objective: Tinnitus is a global public health issue. It is a mysterious and complex disorder of auditory system. Tinnitus is presented as a phantom sensation which is not associated with an external sound stimulus. Hearing loss is considered to be the most important risk factor for tinnitus. Thus, the objective of this study is to determine the type and degree of hearing loss in tinnitus sufferers.
Patients & Methods: An observational study conducted at the ENT/audiology department of Mayo Hospital, Lahore from 1 May 2017 to 30 December 2017. One hundred and ten (n=110) patients of both gender between age 10 to 70 years, who had tinnitus (clinically examined by tuning fork tests and later on confirmed by pure tone audiometry and tympanometry) with history of unilateral or bilateral tinnitus of more than eight months duration were included in the study.
Results: There were 56.4% (62/110) males and 43.6% (48/110) females in the study sample. A total of 25.5% (n=28) were identified as moderate hearing impairment. Moreover, it was also observed in the study that the moderate hearing impairment was more prevalent in people of 10-40 age group (21/110) (P<0.05). The sensorineural hearing loss was more prevalent in 67 patients suffering from tinnitus. Among gender distribution males were having prevalent sensorineural hearing loss (n=55/62) while females were having more conductive hearing loss (n=20/48).
Conclusion: A significant percentage of patients with tinnitus were for period of eight months duration and concluded that moderate degree sensorineural hearing was more prevalent in patients with tinnitus.
