Canal Wall Down Mastoidectomy

AbstractBackgroundRetraction pocket theory is the most acceptable theory for cholesteatoma formation. Canal wall down mastoidectomy is widely performed for cholesteatoma removal. Post-operatively, each patient with canal wall down mastoidectomy has an exteriorised mastoid cavity, exteriorised attic, neo-tympanic membrane and shallow neo-middle ear.ObjectiveThis study aimed to clinically assess the status of the neo-tympanic membrane and the exteriorised attic following canal wall down mastoidectomy.MethodsAll post canal wall down mastoidectomy patients were recruited and otoendoscopy was performed to assess the neo-tympanic membrane. A clinical classification of the overall status of middle-ear aeration following canal wall down mastoidectomy was formulated.ResultsTwenty-five ears were included in the study. Ninety-two per cent of cases showed some degree of neo-tympanic membrane retraction, ranging from mild to very severe.ConclusionAfter more than six months following canal wall down mastoidectomy, the degree of retracted neo-tympanic membranes and exteriorised attics was significant. Eustachian tube dysfunction leading to negative middle-ear aeration was present even after the canal wall down procedure. However, there was no development of cholesteatoma, despite persistent retraction.

AbstractTo obtain the best possible results of treatment of acquired cholesteatoma, we made a subdivision of cholesteatoma types into attic and pars tensa cholesteatomas, and subdivided the latter further into tensa retraction cholesteatoma and sinus cholesteatomas. Tensa retraction cholesteatoma is defined as arising from a retraction or perforation of the whole pars tensa, whereas sinus cholesteatoma is defined as arising from a retraction or perforation of the postero-superior part of the tensa. We present the long-term results obtained in tensa retraction cholesteatomas treated with one stage surgery from 1964 to 1980. Median observation time was 9 years, range 2 to 19 years. Sixty-one ears were treated without mastoidectomy, whereas 71 ears had canal wall-up mastoidectomy and 64 ears had canal wall-down mastoidectomy. The total recurrence rate was 13.3 per cent; 17 ears had residual cholesteatoma, and nine ears had recurrent cholesteatoma. The best results were obtained in ears with an intact ossicular chain where mastoidectomy was not performed. In 49 per cent of the cases, the cholesteatoma was confined to the tympanic cavity without reaching the aditus, antrum or mastoid process. About one-third to one-quarter of the ears had tympanoplasty only, with removal of the cholesteatoma through the ear canal.

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
