Cartilaginous myringoplasty: the endoscopic transcanal procedure.

The objectives of the study are to evaluate the feasibility, results and complications of the endoscopic transcanal cartilaginous myringoplasty. Thirty patients with a tympanic membrane perforation underwent a transcanal endoscopic cartilaginous myringoplasty, between June 2008 and January 2010. Three patients had a residual perforation at 2 months after surgery. At 1 year, the perforation was closed for 29 patients (96 %). There was no case of blunting, lateralization of the tympanic membrane or ossicular injury. Two patients had an iatrogenic superficial cholesteatoma in the tympanic membrane. There was no significant postoperative worsening of sensorineural hearing loss. The preoperative Air Bone Gap (ABG) was not correlated with the size or site of TMP. The evolution of ABG postoperatively was not significant. The statistical analysis was performed by the Student's t test. The endoscopic transcanal cartilaginous myringoplasty is a minimally invasive, effective and reliable procedure in the management of the tympanic membrane perforations.
