“…The surgical techniques used to perform canaloplasty were initially set by Paparella (1966) and Paparella and Kurkjian (1966) and have remained relatively unchanged with only minor differences occasionally being presented. The details of surgical technique have been documented by many authors (Katzke and Pohl, 1982;McDonald et al, 1986;Keohane et al, 1993;Parisier et al, 1996).…”

Acquired medial canal fibrosis is a discrete clinicopathological entity characterized by formation of fibrous tissue in the bony external auditory meatus.Over a seven-year period, a total of 14 operative procedures were performed on 12 ears involving 10 patients. Four cases had followed otitis externa, two were complications of suppurative otitis media, and three cases were iatrogenic. The cause could not be identified in three ears involving two patients.Treatment entails excision of all the fibrous tissue and involved skin, a wide canaloplasty, a meatoplasty, and then reconstruction by split skin graft. Two cases of canal cholesteatoma were encountered. Average follow-up of two years showed hearing improvement in all patients. The only complication was a recurrence of the stenosis in two ears. The paper discusses terminology, aetiology, pathophysiology, diagnosis, and principles of treatment of this condition.

“…Perforation of the drum is one of the commonest complications described by other authors, 4 however, with this technique the drum is always protected from the burr by a Silastic disc and by the infolded medial canal skin tube. Re-stenosis is usually due to a technical fault, either insuf cient bone removal or, as in this series, the use of a bulky, middle temporal ap.…”

“…Soft tissue. Permeatal and endaural approaches for canalplasty have their advocates, 4,6,7 however, the post-auricular approach with canal transection, as described here, not only gives the best appreciation of the bony landmarks, but also allows for good canal skin preservation.…”

“…Although de cient skin can be grafted, donor skin lacks the natural migratory characteristic of canal skin which should be preserved if at all possible. 4 By transecting the canal, the need for complex skin ap design is circumvented with the lateral skin tube being retracted anteriorly out of the way and the medial skin tube kept intact and protected from the burr by a silastic disc. The middle temporal artery ap 3 was used in a handful of cases to provide a vascular bed to encourage epithelialization.…”

Canalplasty is the surgical procedure whereby the external auditory meatus is widened. The indications include exostoses, stenosing external otitis and widening for surgical access. One hundred consecutive ears operated on by one surgeon are reported. The surgical technique is described in detail, paying particular attention to bone removal from the anterior canal wall. In this paper the majority of cases were occasioned by soft tissue rather than bony stenosis. The re-stenosis rate was four per cent and in each case this was associated with the use of a middle temporal artery flap. Partial, transient, delayed facial palsy occurred in two per cent, probably relating to thermal injury transmitted from the burr. A full, spontaneous recovery of facial function occurred in each case. This is a safe and effective technique for canal widening.
