Background/objectives: Continuous positive airway pressure (CPAP) is efficacious in the treatment of obstructive sleep apnea syndrome (OSAS) in patients with Parkinson's disease (PD). However, this treatment is often not well tolerated in this disabled population. We explored, in a pilot study, the efficacy, observance, and usability of mandibular advancement device (MAD) for the treatment of OSAS in this peculiar population.
Patients/methods: Twenty patients with PD and moderate or severe OSAS were included in the study. Ten patients had refused or not tolerated the validated treatment with CPAP so that they were treated with MAD. The patients treated with MAD were matched for sex, age and body mass index (BMI) to 10 patients with PD treated with CPAP. We explored the efficacy of MAD on sleep disorders complaints (PDSS-2) and on sleep recordings. We compared adherence, tolerance and usability with MAD and with CPAP.
Results: MAD improved sleep complaints increasing PDSS-2 scores (85 [55-106] vs 106 [88-126], p < 0.005), and sleep respiratory measures reducing apnea/hypopnea index (AHI) (50.8 [30.0-76.4] vs 9.4 [5.0-45.2], <0.001) and oxygen desaturation index (22.9 [2.1-92.0] vs 3.8 [0.2-34.2], p < 0.05). Observance was higher with MAD than with CPAP. Usability and caregiver satisfaction were higher with MAD than with CPAP whereas side effects were similarly reported.
Conclusion: Mandibular advancement device may be an noteworthy alternative treatment of OSAS in patients with PD.

Division of Oral and Maxillofacial Surgery, Faculty of Dentistry, The University of Hong Kong.
This novel hybrid single-double-single barrel (1-2-1) design for fibula free flap reconstruction addresses the unique challenges presented by Brown Class III mandibular defects, which involve long-span defects at both bodies of the mandible and the chin. The importance of this design lies in its ability to overcome the limitations of traditional approaches in terms of mandible height and pedicle length, while optimizing both functional and esthetic outcomes.The technique utilizes a combination of single-double-single barrel fibula segments to achieve ideal esthetics and support for dental prosthesis across different areas of the mandible.

Background And Objective: Skeletal Class II malocclusion patients frequently exhibit an extended craniocervical position. The study's objective was to evaluate how the craniocervical posture has changed following skeletal class II correction using the Forsus fatigue-resistant device (FFRD).
Methodology: A retrospective analysis was undertaken using the pre- and post-treatment records of 35 skeletal class II patients who used the FFRD to achieve class II correction.

One prior study revealed that a newly developed auto-titrating mandibular advancement device (AMAD) could potentially enhance polysomnographic outcomes in individuals with obstructive sleep apnea (OSA). However, evidence regarding its impact on autonomic nervous system dysregulation in OSA remains limited. In this study, we aimed to compare the effects of conventional mandibular advancement devices (MADs) and AMDA on autonomic function.
