Cephalometric measures correlate with polysomnography parameters in individuals with midface deficiency

Area of Science:

• Orthodontics and Dental Surgery
• Sleep Medicine
• Medical Imaging

Background:

• Midface deficiency can impact craniofacial structure and potentially affect respiratory function during sleep.
• Understanding the relationship between skeletal morphology and sleep disorders is crucial for comprehensive patient care.

Purpose of the Study:

• To investigate the association between cephalometric measurements and polysomnographic parameters in Brazilian patients with midface deficiency.
• To explore how different surgical interventions for midface deficiency relate to sleep quality.

Main Methods:

• A retrospective, observational study involving 48 patients with midface deficiency.
• Patients were grouped based on treatment: surgically assisted rapid palatal expansion (SARME) or maxillary advancement (MA).
• Pre- and post-operative cephalometric and polysomnography data were collected and analyzed using Pearson's correlation.

Main Results:

• Significant associations were found between Body Mass Index (BMI) and Apnea Hypopnea Index (AHI), as well as arousals.
• In the SARME group, correlations were observed between AHI and specific cephalometric points (SNA, MP-H), and arousals and SNA.
• In the MA group, associations were noted between AHI and Co-A, arousals and UAS, and oxygen saturation with SNA, SNB, and Co-A.

Conclusions:

• Cephalometric alterations in the midface are associated with sleep disturbances in patients with midface deficiency.
• Specific cephalometric measurements correlate with polysomnographic parameters, indicating a link between craniofacial structure and sleep quality.
• Findings highlight the importance of considering sleep health in the management of midface deformities.
