The records of 17 patients (aged 5-76years) who underwent transcanal revision procedure using rigid 3-mm diameter, 0°, 30° and 45° endoscopes between 2009 and 2012 were retrospectively reviewed. A wide posterior tympanomeatal flap was elevated via the external auditory canal and then transposed inferiorly in cases of cholesteatoma situated in the middle ear under a tympanic membrane. In certain cases, cholesteatoma was assessed and removed using the endoscopes directly from the radical cavity or from the mastoid cavity remaining after a canal-wall-down procedure. Six patients had originally undergone the canal-wall-up mastoidectomy, 6 patients had a canal-wall-down mastoidectomy and 5 patients had radical mastoid cavities. The interval between the previous and the index surgery ranged between 1 and 6years. The attic was the most common site involved with cholesteatoma, followed by the tympanic portion of the facial nerve, sinus tympani, mastoid, supratubal recess, promontory, round and oval windows. The size of residual/recurrent lesion varied between 3 and 15mm. The patients were followed up 26-67months (mean 52.1months). The single recurrence (a 4-mm pearl over the tympanic portion of the facial nerve) was eradicated by a transcanal re-revision 1year following the index surgery. Minimally invasive TEA can be successfully applied in carefully selected patients with endoscopically accessible cholesteatoma subsequent to various types of mastoidectomy.
