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

<p class="abstract"><strong>Background:</strong> The hallmark of the temporal bone is variation. Various important structures like the facial nerve run in the temporal bone at various depths which can be injured during mastoidectomy.</p><p class="abstract"><strong>Methods:</strong> Twenty wet cadaveric temporal bones were dissected. A cortical mastoidectomy was performed followed by a canal wall down mastoidectomy and the depth of the vertical segment of the facial nerve in the mastoid was determined.  </p><p class="abstract"><strong>Results:</strong> The mean depth of the second genu was 13.82 mm. The mean depth of the stylomastoid foramen was 12.75 mm and the mean distance from the annulus at 6’0 clock to the stylomastoid foramen was 10.22 mm.</p><p><strong>Conclusions:</strong> There is significant variation in the average depth of the facial nerve in the mastoid. </p>

Canal Wall Down Mastoidectomy

<p class="abstract"><strong>Background:</strong> Canal wall down mastoidectomy are still practiced in cases of chronic suppurative otitis media with cholesteatoma to ensure complete disease removal. The resulting cavity is prone to recurrent infection, chronic discharge and frequent care. Reconstruction of the posterior canal wall should be planned by the surgeon. Various techniques for external auditory canal (EAC) reconstruction have been recommended to eliminate open cavity problems. The surgeon should choose the type of grafts either autologous, homografts or synthetic materials. Furthermore, the surgeon should decide whether to do the reconstruction either immediate in the first stage of surgery or delayed as a second stage.</p><p class="abstract"><strong>Methods:</strong> In this study, the ridge was reconstructed at the same time of mastoidectomy by autologous tissues. The presenting study reconstructed the posterior canal wall in four layers; skin, perichondrial flap, cartilage and periosteal flap in that order from the meatal side to the mastoid side. The presenting study included 48 patients (32 males and 16 females) with age ranged from 18-55 and 20-50 years. All included patients were presented at the outpatient clinic with unilateral chronic suppurative otitis media with persistent discharge. They had been operated at our tertiary hospital between January. 2012 to March 2014.</p><p class="abstract"><strong>Results:</strong> Successful reconstruction was obtained in all cases, with no dehiscence or necrosis.</p><p class="abstract"><strong>Conclusions:</strong> The reconstruction of the posterior wall by the four layers technique was successful and efficient. It is recommended to do this repair concomitantly with canal wall down mastoidectomy as one stage surgery.</p>

Prospective Longitudinal

To evaluate the hearing outcome in canal wall down mastoidectomy with middle ear reconstruction, prospective longitudinal study was done at National Institute of ENT, Dhaka from March 2015 to September 2016. Total 22 patients were included in the study undergoing canal wall down mastoidectomy with 6 months postoperative followup. Hearing outcomes were observed and compared with the preoperative hearing tests. Among the 22 patients 9 (39.1% of subjects) patients had hearing gain, 12 (52.2%) had hearing loss and 1 (4.3%) had no change in hearing postoperatively.Although disease clearance is the main objective in canal wall down mastoidectomy, hearing gain can be achieved if combined with ossiculoplasty and tympanoplasty. The hearing gain or loss depends upon the extension of disease and status of the ossicular chain. Most patients usually experience hearing loss more than the preoperative period due to removal of ossicle or ossicles for the sake of disease clearance.
