“…In a recent clinical study, it has not shown significant relationship between the tympanic membrane perforation size and hearing loss in the four analyzed frequencies. 15 In the present study, we also found directly proportional relationship between size of perforation and hearing loss. However, we couldn't find statistically significant air-bone gap on lower frequencies.…”

“…We found a slight female preponderance (male: female ratio was 1:1.17) ( Side distribution: Left ear found to be mostly affected (54%) (Figure 1). This finding was consistent with that of Maharjan et al, Pannu et al and Ibekwe et al and Ribeiro et al 2,3,8,9 Nahata et al showed that bilateral ear involvement was more common. 1 (SA%) distribution: (SA%) was divided into four groups as stated previously.…”

“…His study included patients with inactive chronic otitis media who had a pure conductive hearing loss irrespective to state of the ossicles. 9 The mechanism of conductive hearing loss due tympanic membrane perforation may explained by the effect of two factors. 10  Reduction in the ossicular coupling that is caused by a loss in the sound pressure difference across the inner and outer surface of tympanic membrane which decreases the phase differential between oval and round windows.…”

INTRODUCTIONThere is high incidence of conductive hearing loss caused by perforations of tympanic membrane in chronic otitis media. The results of studies regarding the effect of the size and the site of perforations on the degree of hearing loss conflicting.Some studies show a correlation between degree of hearing loss and the size of tympanic membrane perforation that larger perforation causes larger hearing loss.1-4 The weak point of these studies is the crude estimation of the size of tympanic membrane perforation. In our study, we use a program enable us to calculate the surface area of perforation precisely and designing a logarithmic equation between degree of hearing loss and surface area of perforation.The results of articles were conflicting about the effect of perforation site on the degree of hearing loss. The present studies depend on comparing the mean of the degree of hearing loss of different site of perforation ABSTRACT Background: Study performed to evaluate relationship between surface area of tympanic membrane perforation and degree of hearing loss and the effect of perforation site on that relationship in patients with chronic otitis media. Methods: Seventy-five perforated tympanic membranes from 63 patients aged between 14-45 years with inactive mucosal chronic otitis media included in this study. Rigid endoscope (0 degree) used to take an image for each perforation that analyzed by Autodesk Design Review 2013 program. Degree of hearing loss assessed by pure tone audiometry. Surface area of perforation classified into four groups according to its percentage. Perforation site categorized into three groups regarding its relation to handle of malleus. Data analysis carried out with SPSS program version 17. Results: We studied 34 females and 29 males with different surface area and site of perforations. It observed that with increment of surface area of tympanic membrane perforation, the degree of conductive hearing loss increases (P value=0.000). This relationship expressed in a logarithmic equation. The mean hearing loss of posterior perforation was 1.7±0.5 dB for each 1% of perforation but in anterior perforation was 1.5±0.6 dB for each 1% of perforation (p value 0.185). Conclusions: In chronic otitis media, there is a quantitative logarithmic relationship between surface area of tympanic membrane perforation and degree of conductive hearing loss. The site of perforation does not play a significant role in determining degree of conductive hearing loss.

“…This can be explained by the fact that larger perforations result in greater loss of middle-ear and mastoid volume, hence there is a drop in the pressure difference across the tympanic membrane 1 . However, this was contradicted by Ribeiro et al ., 3 who instead concluded that factors such as ossicular chain disjunctions or fixations, and not perforation size, compromise auditory acuity. They arrived at this conclusion using correlations that did not take into account other independent variables.…”

BackgroundFactors specific to sub-Saharan Africa could have an impact on tympanic membrane perforation characteristics. Obtaining precise information on these characteristics and determinants of hearing loss severity would enable better management.ObjectiveTo determine the relationship between characteristics of tympanic membrane perforation and subsequent hearing impairment.MethodsA cross-sectional study of consenting patients presenting with tympanic membrane perforation was conducted. They were examined using otoendoscopy with a digital camera to obtain precise measurements, followed by pure tone audiometry.ResultsEighty-six cases of tympanic membrane perforation were included. Mean tympanic membrane perforation proportion was 34.1 ± 18.4 per cent. Medium-sized tympanic membrane perforations were predominant (47.7 per cent). Median tympanic membrane perforation duration was 20 years. Tympanic membrane perforation size was found to be a predictor of hearing loss severity (odds ratio = 2.5, 95 per cent confidence interval = 1.02–6.13,p= 0.04).ConclusionTympanic membrane perforation size was a predictor of hearing loss severity in our setting. Site, duration and aetiology seem to have no impact on hearing loss severity.
