Maxillary Diseases

The use of zygomatic implants is a technique that is becoming more and more widespread in daily clinical practice, however, few professionals feel safe and confident in performing this type of procedure. We therefore believe that a line of research focused on simplifying this technique will have an extraordinary impact on the safety of both patients and surgeons. Currently, new surgical guides have emerged that guarantee greater precision in the placement of zygomatic implants. However, no comparative clinical studies have yet been performed to evaluate the degree of accuracy of guided implant placement compared to the conventional freehand technique.

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.
