Inicial nasal mucosa detachment using piezoelectric device in the Le Fort I osteotomy: A technical note.

In maxillary Le Fort I type osteotomy the detachment of the nasal mucosa should be done carefully. Piezoelectric surgery contributed much to increase the safety of osteotomies, despite the initial advantage of minimizing the risk of injury in nervous tissue, mainly in bilateral sagittal split osteotomy; we use the piezoelectric device for the initial detachment of the nasal mucosa in the maxillary osteotomy.

Introduction

In maxillary osteotomy Le Fort I type the detachment of the nasal mucosa should be done carefully, because mucosa tears can produce postoperative bleeding after restoration of blood pressure. Piezoelectric surgery contributed much to increase the safety of osteotomies,[12] despite the initial advantage of minimizing the risk of injury in nervous tissue mainly in bilateral sagittal split osteotomy; we use the piezoelectric device for the initial detachment of the nasal mucosa in the maxillary osteotomy.

Technique

After exposure of the nasal mucosa [Figure 1], we use the tips that were originally developed for sinus lift (Mectron PiezosurgeryR) and completed the detachment of the nasal mucosa [Figure 2] using a conventional form. We recommend that you experiment and different that was found in the literature[3] in our cases when the piezosurgery device is used to complete the maxillary Le Fort I osteotomy, we find increase around 20% in total operative time.
