“…1) In overlay technique there are chances of anterior canal wall blunting, lateralisation of the graft, formation of epithelial pearls, excessive membrane thickness, and longer duration of healing and increased risk of iatrogenic cholesteatoma [4][5][6]. The disadvantages of underlay technique are that the middle ear space is reduced, there are chances of medialisation of the graft [6], less suitable for large anterior perforations [7] and longer healing time.…”

A prospective, cohort, clinical study was conducted at Dr. D. Y. Patil Hospital, Kolhapur from August 2010 to August 2013. The aim was to evaluate the results of type 1 interlay tympanoplasty with respect to graft uptake, hearing improvement and complications. Total of 100 cases with a mucosal type of chronic suppurative otitis media and a large central perforation (involving more than 50 % of tympanic membrane) were operated for type 1 tympanoplasty where the graft was placed by interlay method (below the fibro-squamous layer and above the mucosal or endothelial layer). Patients were followed up with ear microscopy at each follow up visit and an audiometry at the end of 3rd month. Statistical analysis was done by statcal software using paired t test and two sample t test for proportion. 96 (96 %) cases had a successful graft uptake. The mean pre-operative air-bone gap was 36.42 ± 12.0 dB; whereas the mean post-operative airbone gap was 9.7 ± 6.71 dB. Except for residual perforation in four patients and partial tympanomeatal flap necrosis in two patients no other complications were encountered. Thus, we conclude that, the interlay tympanoplasty is a safe and effective method of graft placement for large central perforation.

The perforation size affects the success of tympanic membrane (TM) reconstruction, in addition to the surgical technique used. Large TM perforations present a surgical challenge. The perforation size has been reported to be a prognostic factor, and poorer results are obtained with large versus small perforations. We aimed to evaluate patients who had undergone tympanoplasty for large perforations at our clinic using either the underlay or overunderlay technique and to compare the results in terms of re-perforation, retraction, lateralization, and improvement of hearing. Of 302 patients with chronic otitis media, 114 who had a perforation that involved over 50 % of the pars tensa were enrolled in the study. The underlay technique was used in 61 patients, and the over-underlay technique in 53 patients. In the underlay group, the preoperative mean perforation size was 30.11 ± 5.35 mm 2 (range 20.00-52.00 mm 2 ) (n = 61). In the over-underlay group, the preoperative mean perforation size was 31.41 ± 8.65 mm 2 (range 22.00-48.00 mm 2 ) (n = 53). The graft success rate of tympanoplasty performed using the underlay technique was 89.1 % in 61 patients. Seven (10.9 %) patients had graft failure. The graft success rate with the over-underlay technique in 53 patients was 90.5 %. Five (9.5 %) patients had graft failure in this group. Three graft lateralizations (5.6 %) and two retractions (3.8 %) were observed at 12 months postoperatively in the over-underlay group. However, in the underlay group, no graft lateralization but five retractions (8.2 %) were observed at 12 months. The graft-take rates and hearing improvement results in both groups were successful and compatible with those in the literature.

INTRODUCTIONChronic otitis media is an inflammation of middle ear cleft. It is well accepted that the main purpose of operation is to obtain permanently dry ear and to close the perforation and improve the hearing.1 The use of mastoidectomy is a means to establish drainage of a complicated infection of the ear, sparks little controversy. Well trained, experienced otologists currently remain divided as to the importance of mastoidectomy in the treatment of chronic non-cholesteatomatous suppurative otitis media. However, the use of mastoidectomy to treat chronic drainage or suppuration from otitis media remains an issue of debate. The purpose of this study is to examine the role of the mastoid air cells in the tympanic membrane reconstruction and hearing. The goal is to determine ABSTRACT Background: Chronic otitis media is an inflammation of the middle ear cleft. Infection represents the single major cause for the failure of tympanoplasty inturn affect result of hearing. Cortical mastoidectomy is an effective mode in eradicating the mastoid source of infection. The effect of mastoidectomy on patients without evidence of active infection remains highly debated and unproven. So this study was conducted with the following objectives. This study was undertaken to evaluate the outcome of hearing of type I tympanoplasty with cortical mastoidectomy and type I tympanoplasty alone and to compare the results between these two. Methods: The comparative study comprises of 60 patients with CSOM safe type operated over a period of 2 years. Patients were reviewed after 1 and 3 weeks. The second and third postoperative reviews were done at 3 rd and 6
