“…Sensorineural hearing loss was found to be more in older adults and elderly population compared to adults. The results of studies conducted by Kanjikar et al (2015) [9] and Balasubramanian et al (2015), [8] are in agreement with the present study. The possible reasons for the present observation may be presbycusis witnessed in older individuals.…”

“…The possible reasons for the present observation may be presbycusis witnessed in older individuals. [8,9] The second highest prevalent type of hearing loss in older adults and elderly individuals was mixed hearing loss. The probable reason for the same could be co-occurring stiffened tympanic membrane, impacted wax and presbycusis in older individuals.…”

“…Also, these studies report varied results when the prevalence of ear related problems, distribution of gender and degree of hearing loss are considered. Many studies reveal male preponderance in hearing loss prevalence [2,7,8,9,12] ; however, a study conducted by Kulakarni et al (2014) [10] in Nashik district, Maharashtra, revealed CSOM to be highly prevalent in females. The prevalence rate is also found to be different across regions (e.g.…”

“…Institution based studies like study conducted by Devadiga et al (2013) [7] reports the prevalence of auditory disorders to be 62% (Among communication disorders) in Manipal, Karnataka. Hospital data based studies conducted by Balasubramanian et al (2015) [8] at Tanjavur, Tamilnadu and Kanjikar et al (2015) [9] in Bidar, Karnataka have revealed a high prevalence of hearing loss in males compared to females. They also found the sensorineural hearing loss to be present more in elderly individuals and conductive hearing loss to be present more in younger individuals.…”

BACKGROUND Prevalence of hearing loss varies across studies owing to methodological differences and regional differences. In the light of newly launched and running hearing health care programs, there is a great need of region-specific prevalence estimation to support proper planning of these programs. MATERIALS AND METHODS Retrospective analysis of audiograms of individuals (1987), who visited Medical Teaching Institute of Mandya, was carried out for a period of eighteen months. Age wise and gender wise comparison of type and degree of hearing loss was carried out to analyze the effect of respective variables. RESULTS High occurrence of hearing loss was found in males, adult and older adult age groups. Sensorineural hearing loss and moderate degree of hearing loss had higher frequency compared to other types and degrees of hearing losses. CONCLUSION Observation of high prevalence of mild-to-moderate degree and sensorineural hearing loss necessitates organisation of appropriate and tailor-made awareness, early identification and rehabilitation programs to address specific target groups.

Association between smoking and hearing status: a comparative study between smokers and non – smokers

et al. 2017

Background: Smoking, age, gender, socioeconomic class and education may contribute to the hearing loss. In this study hearing loss between smokers (current and ex) and non smokers was compared. Materials and Methods: 145 smokers [79 current (68 males, 11 females) and 66 ex smokers (60 males, 6 females)] and 145 non smokers (69 males, 76 females) were studied. Modified Kuppuswamy scale and smoking index were used. Hearing loss was assessed by Audiometry. P value of<0.05(unpaired t test and chi square test) was taken as statistically significant. Result: Statistically significant and non significant differences were found between the mean age and educational status of current-ex smokers and smokers-non smokers respectively. Statistically significant and non significant differences were found between the socioeconomic status of smokers-non smokers and current-ex smokers respectively. Difference was significant between smoking index of current and ex smokers (p=0.003). 70.05% males had hearing loss as compared to females (49.46%). About 59.24% and 26.09% hearing loss cases belonged to low education and upper and upper middle social class respectively. 68% and 24.24% of moderate and severe smoking index were of professional to graduate educational status. 36.17% and 30.30% of moderate to severe smoking index belonged to upper and upper middle socioeconomic class. 73.91% were from low social classes. 47.59% non smokers and 25.51% smokers had no hearing loss. The severity of hearing loss was more in heavy smokers. Conclusion: Hearing loss associated with smoking was found to be more in male gender, advancing age, low socioeconomic and educational classes.

This retrospective study was carried out to know the incidence of unilateral sensorineural hearing loss (USNHL) (type and degree). (1) To know the incidence of USNHL (other ear being normal) in patients undergoing Pure Tone Audiometry (PTA) for hearing loss (HL). ( 2) To establish the type and degree of USNHL in patients. Study was conducted over a period of more than 4 years to find out the incidence and pattern of USNHL (other ear being normal) in the patients attending ear, nose, and throat outpatient department (OPD) with a complaint of HL. Pure tone audiometry data of 10,000 cases between August 2014 and December 2018 with HL were analyzed for this study. Demographic characteristics were compared with types and degrees of unilateral sensorineural hearing impairment. A total of 10,000 OPD cases who had a complaint of HL and had undergone pure tone audigram (PTA) in a period of more than 4 years in the Department of Otorhinolaryngology and Head and Neck Surgery were studied. SNHL type was the highest with 3935 cases (39.3%). Out of 3935 cases of SNHL, 1436 (36.50%) were USNHL-out of which, only 872 cases (60.72%) had USNHL with other ear being normal; this constituted the study group, i.e., 872 cases (8.72%) out of 10,000 PTA and 872/3935 (22.16%) of SNHL cases. Hence, incidence of USNHL (with other ear being normal) is 8.72% among all cases of HL and 22.16% among cases of SNHL. Age of cases ranged from 8 to 76 years (mean age -39.5 years). Male:Female ratio was 1.6:1.0. Both ears were almost equally involved. 35.6% cases had profound ([ 90 dB) hearing loss, followed by mild (25-40 dB) in 32.1%.
