“…Sakagami et al [6], in their study of CSOM, observed tympanic membrane perforation with intact ossicular chain in 90.1 % (82 out of 91) cases and 9.89 % of their cases had ossicular involvement. In our study, we found that the tympanic membrane perforation with intact ossicular chain was in 76 cases (76 % cases) and 24 (24 %) of our cases had ossicular involvement (Table 3).…”

There are not many studies on the effect of the site and size of the perforation on the hearing loss. This study is set to investigate the relationship between the size and site of perforation and hearing loss. This study was carried out between September 2011 to September 2013, at a tertiary care centre during which 100 cases of chronic otitis media tubotympanic type having central perforation were selected. All patients underwent, tympanoplasty using temporalis fascia/cartilage graft, underlay technique with or without simple mastoidectomy/modified radical mastoidectomy and followed up for 3 months and evaluated for graft uptake and hearing improvement with respect to size and site of TM perforation. To measure the size of perforation intra-operatively, thin transparency sheet was used, on which a graph paper of 1 × 1 mm(2) size was printed. Significant relationship was observed between size and site of tympanic membrane perforation with hearing loss. Perforations which were involving all four quadrants (AS + AI + PS + PI) are having maximum residual perforations after the surgery. In relation with size, subtotal perforation were having more residual perforations postoperatively, followed by medium sized perforations. An inherent relationship noted between ossicular involvement and hearing loss, maximum average hearing loss was observed in those cases, where all three ossicles (malleus, incus & stapes) were involved, also more hearing loss was noted in posterior perforations.

“…Greater hearing loss was observed with longer duration of disease in other studies which have not specified if it's sensorineural or conductive which could be the probable cause for such conclusion moreover in presence of a chronic perforation and frequent ear discharge there could be passage of toxin through the round window membrane causing sensory deafness. [10][11][12] Since we've considered only AB gap and not individual thresholds hence we're certain that only membrane perforation with an intact ossicular chain affect the conductive hearing loss and not the duration of the disease.…”

CSOM can lead to conductive hearing loss of up to 60 dB, which constitutes a serious handicap and the baseline investigation to assess the hearing in outpatient basis is Pure Tone Audiometry (PTA) which gives qualitative and quantitative analysis of hearing loss. 4This study is an attempt to correlate the amount of conductive hearing loss with duration of disease and pattern of tympanic membrane perforation in CSOM -TTD.The study was done with the aim to study the correlation of conductive hearing loss with the pattern of the tympanic membrane perforation and duration of the ABSTRACT Background: The aim of the study was to assess the degree of hearing loss with the pattern of tympanic membrane perforation in tubotympanic type of chronic suppurative otitis media (CSOM TTD). cases aged between 20-50 years with CSOM TTD were included in the study. Detailed clinical examination and history was carried out followed by hearing evaluation by pure tone audiometry. All the data collected was statistically analyzed. Results: 110 patients with 137 perforated tympanic membrane, aged between 20 to 50 years, were included in the study. Large central perforation involving all the four quadrants was the most common otologic findings. Significant correlation observed between size of perforation and degree of hearing loss (p value-0.018) and no significant relation is observed between site of perforation and degree of hearing loss (p=0.107). Conclusions:The larger the perforation, the greater the decibel loss in sound perception. The location of perforation does not have significant effect on magnitude of hearing loss.
