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:\n\nCan 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?\n\nIn 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.",[27],"Maxillary Diseases","RECRUITING","2026-01-23",{"date":31,"type":32},"2026-01-27","ACTUAL",{"date":34,"type":32},"2025-05-01",{"date":36,"type":21},"2026-06-10",{"name":38,"class":39},"Wenzhao Guan","OTHER",1,{"id":42,"slug":43,"hasResults":11,"nctId":44,"briefTitle":45,"officialTitle":46,"acronym":4,"eligibilityCriteria":47,"healthyVolunteers":11,"sex":16,"minAge":48,"maxAge":49,"enrollmentInfo":50,"targetDuration":4,"studyType":22,"phases":52,"briefSummary":53,"conditions":54,"keywords":4,"overallStatus":28,"whyStopped":4,"lastUpdateSubmitDate":55,"lastUpdatePostDateStruct":56,"startDateStruct":58,"completionDateStruct":60,"leadSponsor":62,"locationsCount":40},"100587912","patient-satisfaction--abutment-teeth-health-in-maxillectomy-patients-100587912","NCT06934551","Patient Satisfaction & Abutment Teeth Health in Maxillectomy Patients","Patient Satisfaction & Abutment Teeth Health in Maxillectomy Patients Rehabilitated With Laser CAD CAM & Conventionally Constructed Obturators","Inclusion Criteria\n\n* Patients with hemi maxillectomy\n* Sufficient number of natural teeth not less than 5 teeth\n* Age between 30 and 60 years\n* Intact soft palate\n\nExclusion Criteria\n\n* Cognitive impairment\n* Heavy smokers\n* Patients exposed to radiotherapy","30 Years","60 Years",{"count":51,"type":21},20,[24],"randomized controlled trial in maxillectomy patients with two types of obturators with different manufacturing techniques",[27],"2025-04-11",{"date":57,"type":32},"2025-04-18",{"date":59,"type":32},"2024-12-10",{"date":61,"type":21},"2026-12",{"name":63,"class":39},"Cairo University",{"id":65,"slug":66,"hasResults":11,"nctId":67,"briefTitle":68,"officialTitle":68,"acronym":4,"eligibilityCriteria":69,"healthyVolunteers":70,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":71,"targetDuration":4,"studyType":22,"phases":73,"briefSummary":74,"conditions":75,"keywords":78,"overallStatus":84,"whyStopped":4,"lastUpdateSubmitDate":85,"lastUpdatePostDateStruct":86,"startDateStruct":88,"completionDateStruct":90,"leadSponsor":92,"locationsCount":40},"100551435","effects-of-ultrasound-guided-maxillary-nerve-block-performed-after-bimaxillary-osteotomy-in-adult-patients-100551435","NCT06460051","Effects of Ultrasound-guided Maxillary Nerve Block Performed After Bimaxillary Osteotomy in Adult Patients","Inclusion Criteria:\n\n* Patients undergoing scheduled bimaxillary surgery\n\nExclusion Criteria:\n\n* refusal to participate in the study\n* patients scheduled for bimaxillary surgery together with another complementary surgical procedure (such as rhinoplasty, blepharoplasty)\n* age \\\u003C 18 years\n* reinterventions\n* urgent surgeries\n* allergies to local anesthetics\n* allergies to anti-inflammatories\n* allergies to opioids\n* ASA ≥3.",true,{"count":72,"type":21},50,[24],"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.
