Objective: To evaluate Hearing Status in Pre and Post-operative Canal Wall Down Mastoidectomy with Type III Tympanoplasty with or without cartilage augmentation. Methods: This was a prospective study, done in Otolaryngology & Head Neck Surgery department of Sir Salimullah Medical College Mitford Hospital(SSMCMH) and Bangabandhu Sheikh Mujib Medical University(BSMMU) , Dhaka, Bangladesh. 1stJuly to 31st December, 2012. Forty patients were studied in this series. Results: The results concluded that mean pre and post-operative air bone gap were 38.5 dB and 29.69 dB respectively with a net gain of 8.81 dB in Canal wall down mastoidectomy with cartilage augmented Tympanoplasty type III which is statistically significant. The postoperative PTA-ABG ranged from 25-36 dB , the ABG closure was 11-15 dB in 40% case. Whereas mean pre and post-operative air bone gap were 37.19 dB and 34.19 dB respectively with a net gain of 3 dB in Canal wall down mastoidectomy without cartilage augmented Tympanoplasty type III which is statistically insignificant. The post-operative PTA-ABG ranged from 26.25-41.75 dB, the ABG closure was 0-5 dB in 35% case. Conclusion: Hearing results after cartilage augmentation in type iii Tympanoplasty showed improvement at individual and mean post-operative PTA-ABG and also improvement in ABG closure suggesting thin cartilage disc increased the effective vibrating area of tympanic membrane graft.

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
