Association between the Obstructive Sleep Apnea and Cephalometric Parameters in Teenagers.

Area of Science:

• Orthodontics
• Pediatric Sleep Medicine
• Craniofacial Biology

Background:

• Obstructive sleep apnea (OSA) is prevalent in children and adolescents.
• Class II malocclusion and vertical growth patterns can reduce oral airway volume, increasing OSA risk.
• Understanding the link between dental occlusion and OSA is crucial for effective management.

Purpose of the Study:

• To investigate the relationship between cephalometric parameters and OSA indicators in adolescents.
• To explore collaborative strategies between orthodontists and somnologists for treating OSA in this age group.
• To identify specific orthodontic factors associated with OSA in adolescents.

Main Methods:

• Analysis of data from 41 adolescents diagnosed with OSA.
• Orthodontic assessments including cephalometric analysis were performed.
• Polysomnography was used to evaluate sleep patterns and breathing events.

Main Results:

• Distal occlusion was frequently associated with dental development discrepancies.
• Palatal inclination of upper incisors was observed in 60.98% of patients with distal occlusion.
• Cephalometric analysis indicated a distal mandibular position (SNB 79.4±3.1°) and potential mandibular retrognathia (SNA > normal, ANB 4.3±1.9°).
• High prevalence of tonsillar and/or adenoid hypertrophy was noted (30 patients).
• Masticatory muscle activity during sleep occurred in 22.0% of patients.

Conclusions:

• A multidisciplinary approach is essential for improving OSA diagnosis and treatment in children.
• Correction of growth and development processes is key in managing pediatric OSA.
• Integrating orthodontic and sleep medicine expertise can enhance patient outcomes.
