Piezosurgery versus conventional osteotomy in orthognathic surgery: a paradigm shift in treatment.

The aim of the study was to compare in a randomized controlled clinical trial the use of the piezoelectric osteotomy as an alternative to the conventional approach in terms of surgery time, intraoperative blood loss, cut quality, nerve injury, and costs.One hundred ten patients who had orthognathic surgery procedures with bimaxillary osteotomy were divided into 2 groups: group A was treated with a piezosurgery device, and group B, with a reciprocating saw and bur.The piezosurgical bone osteotomy permitted individualized cut designs.

Bilateral pneumothorax after orthognatic surgery.

Among complications in orthognathic surgery, the insurgence of pneumothorax is very rare. Pneumothorax is the presence of air or gas in the pleural cavity and it is rare complications in the postoperative oral and maxillofacial surgery patient. The clinical results are dependent on the degree of collapse of the lung on the affected side.

Combined rhinoplasty and genioplasty: long-term follow-up.

Importance: Long-term follow-up reference for experienced clinicians dedicated to profileplasty.

Objective: To evaluate the long-term results and complications of combined rhinoplasty and genioplasty.

Design: Retrospective study including objective and subjective evaluation before and after 3 years of undergoing simultaneous open rhinoplasty and genioplasty among a cohort of 90 patients.
