Objective: To compare pharyngeal airway dimensions and hyoid bone position in different craniofacial growth patterns.
Methods: In total, 611 patients divided into 9 subgroups were compared according to malocclusion classification and vertical growth pattern, and these subgroups were compared in terms of pharyngeal airway and hyoid measurements. A two-way ANOVA test was used to compare the findings of the subgroups.
Results: No significant difference was found for the pharyngeal measurements between the groups (p>0.05). The vertical airway length (PNS-Ep) was significantly shorter in the Class III malocclusion group (p<0.05) and in the hypodivergent group (p<0.05). No statistically significant difference was found between any subgroups in any measurements of the position of the hyoid bone (p>0.05).
Conclusion: The pharyngeal airway dimensions and hyoid bone position are similar among individuals in the sagittal direction. The vertical airway length is significantly shorter in Class III and hypodivergent individuals.

Risk factors and prognosis analysis of dysphagia after occipitocervical fusion surgery: a retrospective study of 43 cases.
J Orthop Surg Res
January 2025
Department of Spine Surgery, The First Affiliated Hospital of Fujian Medical University, Fuzhou, 350004, China.
Objectives: To analyze the risk factors for developing dysphagia after occipitocervical fusion (OCF) and investigate possible mechanisms and prognosis.
Methods: The case data of 43 patients who underwent OCF were retrospectively reviewed. Patients were divided into group A (dysphagia group) and group B (non-dysphagia group) based on Bazaz scoring criteria.

To explore the changes of atlantoaxial joint spaces and pharyngeal airway after combined orthodontic-orthognathic treatment in skeletal class Ⅲ patients with mandibular deviation. A total of 34 adult skeletal class Ⅲ patients (10 males and 24 females) with mandibular deviation who received combined orthodontic-orthognathic treatment at the Department of Orthodontics and the Department of Orthognathic Surgery in the Stomatological Hospital of Chongqing Medical University from August 2014 to October 2021 were retrospectively selected. The patients were 22 (5) years old (18-33 years).

Objective: To determine whether folded-flap palatoplasty (FFP) results in improved respiratory outcomes compared to standard staphylectomy (SS).
Methods: English Bulldogs were randomized to receive FFP or SS in a parallel, equal-allocation, prospective study design at a single institution. Exercise-tolerance testing (ETT), arterial blood gas, head CT, and an owner survey were completed preoperatively and at recheck (approx 30 days postoperatively).
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.

Objectives: This study aims to compare the effects of two orthodontic treatment modalities for skeletal class Ⅲ malocclusion on specific changes in airway volume, morphology, palatal angle, mandibular rotation, and bone displacement. Results provide scientific evidence for the selection of orthodontic treatment plans and reduce the risk of developing obstructive sleep apnea hypopnea syndrome (OSAHS).
Methods: Thirty-six patients diagnosed with skeletal class Ⅲ malocclusion at the Department of Orthodontics, the Affiliated Stomatological Hospital of Nanjing Medical University from September 2018 to December 2023 were divided into two groups: orthodontic-orthognathic treatment group (18 patients) and camouflage orthodontic treatment group (18 patients).
