Effects of Ultrasound-guided Maxillary Nerve Block Performed After Bimaxillary Osteotomy in Adult Patients

Sponsor: Servei Central d'Anestesiologia

Summary

Bimaxillary osteotomy is a surgery procedure of the orthognathic surgery field for correction of dental and facial abnormalities, for both functional and aesthetic cases. The incidence of this abnormality is 5-10% of the population, and the etiology is unknown, with genetic, environmental and embryonic factors related. The surgery technic is complex, and requires osteotomy of the maxilla and jaw, which allows toward, forward, impact and rotation of these bones to fix the edges of the face. The anesthetic management of these patients is a challenge because of the difficult airway management and the perioperative pain control. Multimodal approach for pain control is a fact, and the use of local and regional anaesthesia is mandatory. The investigators propose bilateral ultrasound-guided suprazigomatic maxillary nerve block after bimaxillary osteotomy for a proper control of postoperative pain.
