“…As our study shows, preoperative stage of PTR is not a predictor for long incus process defect. Some authors consider that the contact of a retracted PT with the promontory increases the hearing threshold, more than a retraction involving the incus, as has been shown in an endoscopic study (15). On the contrary, in combined retractions, both proved to not be a predictor of a long incus process defect, but they did both predict a long incus process+stapes suprastructure defect.…”
