Endoscopically Assisted, Intraorally Approached Corrective Rhinoplasty

Abstract

In the field of facial surgery, operations that require guesswork can result in unexpected complications. One example of such "blind" facial surgery is the lateral osteotomy procedure in corrective rhinoplasty. In most conventional corrective rhinoplasties, the postoperative results of a lateral osteotomy can be controlled by the surgeon's visual perception or manual dexterity; therefore, an experienced surgeon is indispensable in such elaborate operations. Until now, reports have focused on the endoscopic approach through the nasal dorsum or septum through the nostril. However, because of the difficulty in handling the endoscope with osteotomy instruments, it is considered difficult to perform a precise lateral osteotomy procedure using that approach. The authors think the intraoral endoscopic approach should be considered a viable alternative in corrective rhinoplasty. Through small, bilateral gingivobuccal incisions, both the piriform apertures and nasal bones can be easily exposed, and the exact level of the lateral osteotomy can be confirmed directly under the endoscope. The lateral osteotomy is made simply with a reciprocating saw, and symmetrical cutting can be ascertained during the operation. Sometimes, a particular osteotomy level or the proper repositioning of osteotomed segments can be readily evaluated with assistance from the endoscope during the operation. Eleven cases using this procedure were performed over the past 3 years. These endoscopic repairs for a deviated nose were quite helpful for visual confirmation and accurate correction. No complications occurred when using the endoscope with this procedure.
