Upper airway changes after orthognathic surgery in patients with skeletal class III high-angle malocclusion and mandibular deviation.
Clin Oral Investig
January 2025
College of Stomatology, Dalian University, Dalian, Liaoning, 116622, China.
Objectives: This study analyzed the differences in the upper airway of patients with skeletal Class III high-angle malocclusion with and without mandibular deviation, and further investigated whether there are differences in the changes in upper airway space after orthognathic surgery between the two groups.
Materials And Methods: 15 patients with skeletal Class III high-angle malocclusion and mandibular deviation, and 15 patients without mandibular deviation were selected to explore the impact of mandibular deviation on the upper airway. Additionally, 16 patients with mandibular deviation undergoing orthodontic-orthognathic combined treatment, and 13 patients without mandibular deviation, were selected to investigate the differences in the changes in upper airway space after orthognathic surgery between the two groups.
Myelodysplastic syndromes (MDS) are age-related diseases characterized by bone marrow (BM) dysfunction and an increased risk of developing acute leukemia. While there is growing evidence highlighting the crucial role of the BM microenvironment (BMME) in MDS, the specific influence of inflammation on BMME changes, as well as the potential benefits of targeting cytokines therapeutically, remain to be elucidated. We previously found interleukin-1 (IL-1) to be a driver of aging phenotypes of BMME and hematopoietic stem and progenitor cells (HSPCs).

Stafne bone cavity, also known as static bone cavity, is a rare bony defect on the lingual side of the mandible. It rarely shows progressive changes, and requires only follow-up bservation. This article described a case of progressive enlargement of a Stafne bone cavity and analyzed the causes of its progress by reviewing relevant literature.

Dept. of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Bengbu Medical University, Bengbu 233004, China.
Objectives: This study aims to analyze the biomechanics of three kinds of rigid internal fixation methods for condylar head fractures.
Methods: A three dimensional finite element model of the normal mandible was constructed. It was then used to prepare condylar head fracture finite element model and three kinds of rigid internal fixation finite element model (unilateral tension screw, bilateral tension screw, tension screw+titanium plate).
A retrospective study of the effects of different surgical procedures on the mandibular nerve canal involved by odontogenic keratocyst.

Dept. of Stomatology, the First Affiliated Hospital of Bengbu Medical University, Bengbu 233004, China.
Objectives: This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment.
Methods: Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed.
