Objectives: To analyze hearing outcomes following Type 3 tympanoplasty with stapes columella grafting after canal wall down mastoidectomy and determine disease recurrence rates in patients undergoing this procedure. Methods: This retrospective cohort analysis examines patients undergoing Type 3 tympanoplasty with stapes columella grafting following canal wall down mastoidectomy for cholesteatoma at a tertiary care center from 2005 to 2015. Patient charts were reviewed for demographic data, diagnosis, and operative details. Patients were included in statistical analysis if they were found to have undergone the aforementioned procedure. Evaluation of hearing improvement was made by comparing preoperative air-bone gap (ABG) and ABG at follow-up at 6 months and 1 year postoperatively. Results: Nineteen patients met criteria for this study. Erosion of the otic capsule, posterior fossa plate, or tegmen was noted in 37% of cases, highlighting disease severity. Eighteen (95%) had undergone prior otologic surgery. Mean time to short-term follow-up was 6 ± 3 months. The average short-term ABG was 26 ± 11 dB HL; 26% achieved an ABG <20 dB, and 58% achieved an ABG <30 dB. Fifteen had follow-up at least 1 year postoperatively (mean = 33 ± 16 months). At longer-term follow-up, mean ABG was 25 ± 10 dB HL; 33% achieved an ABG <20 dB, while 66% achieved an ABG <30 dB. Hearing remained stable over time ( P = .52). At date of last clinical follow-up, only 1 (5%) patient had undergone revision for recurrent disease. Conclusion: In some patients undergoing canal wall down mastoidectomy for advanced or recurrent cholesteatoma, Type 3 tympanoplasty with stapes columella grafting yields marginal hearing benefit. This type of reconstruction is a viable option in this challenging patient cohort, particularly as it is associated with low rates of revision surgery.

AbstractObjective:To analyse patients with cholesteatoma undergoing canal wall down mastoidectomy together with ossicular reconstruction with a titanium prosthesis, in order to identify factors associated with hearing outcomes.Study design:Retrospective review of 97 cases undergoing single-stage surgical management.Methods:All patients underwent canal wall down mastoidectomy. Kurz titanium ossicular prostheses were used for ossicular chain reconstruction. Pre-operative and post-operative air conduction and bone conduction hearing thresholds were obtained at 500, 1000, 2000 and 3000 Hz.Results:The mean pure tone average improved from 46.02 ± 14.54 dB pre-operatively to 29.32 ± 14.64 dB post-operatively, for both total and partial ossicular replacement prosthesis groups combined. The mean air–bone gap improved from 30.38 ± 11.12 dB pre-operatively to 15.62 ± 9.65 dB post-operatively, for both groups combined.Conclusion:Reconstruction with a titanium prosthesis offers good functional results when performed during canal wall down surgery for advanced cholesteatoma, as a single-stage procedure.

Canal wall window (CWW) tympanomastoidectomy is a modified form of attico-antrostomywhich can be a substituted for canal wall down procedure. A retrospective study of 84 casesof CWW tympanomastoidectomy were collected from department of otolaryngology and Headnecksurgery, BSMMU and ENT Foundation Hospital, Dhaka from June 2005 to July 2009.In this study majority of the patients were 16 to 48 years 57(67.86%). Male female ratio was3:1. Most of the patients were found cholesteatoma 27 (32.14%), granulation tissue 25(29.76%),retraction pocket 22(26.19%),Postoperative hearing gain (mean three frequency pure tone air bone gap) assessed 3 monthsafter primary surgery, most of the patients 34(40.48%) had gain 20dB+, 26 patients (30.95%)had gain 10dB+,18 patients (2143%) had gain 30dB+.Materials used in tympano-ossiculoplasty were chonchal cartilage, sculptured incus, PORPand TORP. Most of the patients we used incus reposition 36(42.86%), cartilage ossiculoplasty28(33.33%), PORP 12(14.29%) and TORP 8 (9.52%).Post operative followup of the patient was done in 1 month, 3 month and 6 month intervals andcondition of external auditory canal assessed. Dry ear were found 70 patients (83.33%), moistear were found 8 patients (9.52%) and 6 patients (7.14%) were found purulent dischargingears and later canal wall down mastoidectomy done .Key words: Canal wall window; Tympanomastoidectomy.DOI: 10.3329/bjo.v16i1.5774Bangladesh J Otorhinolaryngol 2010; 16(1): 3-8
