Schneider Membrane Preservation With In Situ Osteogenesis: A Modified Maxillary Resection Study

This case series study aimed to find out if a new surgical technique that preserves the sinus membrane during upper jaw removal can help patients regenerate bone and recover function better after surgery. The study included two female patients with jaw tumors who were not suitable for or did not want complex reconstruction with tissue flaps. The main questions the study tried to answer were: Can the preserved sinus membrane help new bone grow spontaneously in the jaw defect area after surgery? Can this new method reduce common complications seen with traditional surgery, such as oronasal fistula and empty nose syndrome? How well can patients recover in terms of chewing, swallowing, speech, and quality of life after the procedure? In the study, during surgery, the surgeon carefully separated and preserved the sinus membrane from the bone that needed to be removed. After surgery, patients were followed with regular CT scans to check new bone growth. They also underwent tests to measure chewing force, swallowing ability, speech function, and quality of life to evaluate the long-term outcomes of this technique.

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

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.
