External ear canal cholesteatoma after ventilation tube insertion and mastoidectomy

Abstract

There could be more than one potential delicate mechanism of developing EEC in the ear with VT insertion and mastoidectomy. It is necessary to perform routine otologic surveillance in all patients with tubes. Affected ear CT scan is very helpful in showing the extent of cholesteatoma and bony defects, which could not be assessed by otoscopic examination alone.

Hearing Status and Ventilation Tube at Time of Palatoplasty in Cleft Lip and Palate Patients: A Retrospective Study

“…The overall rate of HL in our group was 40%, analogous with other retrospective studies [ 2 ]. Although early hearing rehabilitative intervention has gained some support in patients with CLP, a more conservative approach is favored by other groups because of the risk of morbidity associated with repeated TT insertion, including persistent perforations, myringosclerosis, and cholesteatoma [ 20 ]. Persistent perforation after VT was low in our case series (7.5%).…”

Iatrogenic Cholesteatoma Arising at the Bony-Cartilaginous Junction of the External Auditory Canal

“…Unlike the patients in this study who presented with retraction cholesteatomas into the mastoid, EACC is a different disease process. Iatrogenic EACC may arise after lateral graft tympanoplasty or entrapment of epithelium under a vascular strip or skin graft (20). Although epithelial inclusion cysts are common and can be managed in the office, true EACCs causing bony destruction are rare (21).…”
