In conclusion, no correlation between high-frequency hearing loss and use of a powered drill for canalplasty during type I tympanoplasty was found in this pediatric population.
Importantly, no significant difference was observed in BC hearing results pre- and postoperatively between 500 and 4,000 Hz, which would suggest that use of a powered drill during canalplasty is safe.
Stapes fixation, cholesteatoma involvement of the malleus, ineligible mucosal inflammation, wet middle ear, and accompanying bony canalplasty
were the intraoperative exclusion criteria for this study and were checked from operation notes.
Canalplasty can be attempted in recurrent cases of keratosis obturans with promising results.

Comparitive study of hearing improvement in type 1 tympanoplasty with and without canalplasty
The three most common indications for Thiersch grafting are for skin repair following (1) a canalplasty
for the treatment of congenital external auditory canal atresia or intractable otitis externa, (2) a canal-wall-down mastoidectomy, and (3) a tympanoplasty with a moderate to large canalplasty
In cases of severe canal stenosis, wide canalplasty
can be performed.
