“…13 Hence, the most common reconstruction model for an ossicular defect is a type III tympanoplasty. 14,15 In this type of tympanoplasty, whether the stapes is movable or fixed is a crucial factor in obtaining improved hearing results. For patients with mobile stapes, hearing results have been shown to be significantly better than for those with fixed stapes.…”

“…1,5,15,[19][20][21][22] Long-term follow up requires commitment and resources that can be difficult to achieve. To our knowledge, reports on the long-term follow up for type III tympanoplasty are rare; the rates of post-operative ABG closure to within 20 dB range from 48 to 81.3 per cent.…”

“…25 of our patients had a post op air bone gap of 0 to 20 dB hence 83.33 percent of the patients had an air bone gap of 0 to 20 dB post op which can be compared to Iiurato et al who in their retrospective review of large series of Austin-Kartush type A ossiculoplasties of various surgeons showed air-bone gap of 0 to 10 dB for 20% to 68% of patients and of 0 to 20 dB for 54% to 93% of patients post-surgery. 17 The above observations remained unchanged over the next 3 months and these patients had similar hearing threshold even 6 months post-surgery, this is a testament to the survival of the cartilage in the middle ear and also to the stability of the assembly for this period of time. Extrusion of the cartilage was not noticed in any of the patients and hence is not noted as a complication.…”

Background: Chronic suppurative otitis media is a highly prevalent disease in developing countries. Hearing loss associated with this disease is significantly more in cases associated with ossicular necrosis along with tympanic membrane perforation. Methods: We would like to present a study of such cases of mucosal chronic suppurative otitis media associated with lenticular process necrosis treated by cartilage interposition ossiculoplasty. The patients were followed up for a minimum period of 6 months and their pre op and post op hearing was documented and analyzed. Results: An average air bone gap of 39.07 decibels in pre op was reduced to 18.13 decibels in post-operative period and these improvements persisted over 6 months of follow-up. Conclusions: We have hereby concluded that the hearing improvement is comparable to other methods of ossiculoplasty with minimum disruption of natural hearing assembly in lenticular process of incus necrosis.

“…11 Shinohara et al 12 reported 68% success rates with PORP where only the incus needs to be replaced This compares with 46% of TORP where incus and stapes superstructure are absent. Palva and Ramsay, 13 looked at the outcome of 281 myringoplasties in their department The closure rate in Palva s hands was 97%, while in hands of other members it was 74%.…”

AIM:To determine the hearing improvement in tympanoplasty by preoperative and postoperative audiometric evaluation after I month and 3 months and 6 months of tympanoplasty. MATERIALS & METHODS:50 Patients presenting having CSOM and presenting with complaints of deafness or ear discharge in ENT OPD at Basaveshwar Teaching and General Hospital, Gulbarga from 2012 to 2014. Pre-operative audiometry and appropriate investigation was done followed by tympanoplasty. Patient was followed up regularly with post-operative audiometry at 1 month, 3 month and 6 month. Assessment of hearing improvement was done by comparing preoperative and postoperative A-B gap at speech frequency. RESULTS: The number of patients who underwent Type l tympanoplasty was 26, Type II was 5, Type III was 6 and Type 4 was 1. They had a mean A-B gap closure of 10.3dB, 10.2dB, 9.33dB and 5dB respectively. When mastoidectomy was included as a part of the procedure the hearing improvement was comparatively lesser. The mean Air-Bone gap closure was 8.9dB.The mean A-B gap closure was 10.2 dB for temporalis fascia graft, 4dB for temporalis fascia with conchal cartilage and 9.2dB in case of autograft incus. The mean A-B gap closure of medium, large and subtotal perforation were 4.7, 11.7 and 6.6 respectively. The total success rate in terms of graft uptake rate was 88%. CONCLUSION: The study shows that A-B gap closure is greatest for Type I followed by Type II, Type III and Type IV in decreasing order. Tympanoplasty in which modified radical mastoidectomy was a part of the procedure did not give as much hearing improvement as otherwise. The grafting material also had significant bearing on the success of surgery. The Airborne gap closure is greatest for temporalis fascia graft than dura or autograft incus. Air-bone gap closure is also greater for temporalis fascia when used alone compared to when it is used along with conchal cartilage. Reperforation rates are higher when temporalis fascia is used alone compared to cases where reinforcement with cartilage is done showing greater graft stability in cartilage tympanoplasty.
