The etiology of PSDB is multifactorial, with adenoid and palatal tonsil enlargement being the most common cause. While adenotonsillectomy is recommended as the primary treatment, residual SDB may result in craniofacial skeletal deformities contributing to upper airway constriction. Typical craniofacial phenotypes of SDB include excessive vertical growth and constriction of the maxilla, a retruded mandible, and posterior rotation, known as a Class II hyperdivergent pattern. Conversely, Class III with an underdeveloped maxilla shows a relatively lower risk for SDB due to reduced nasal cavity and nasopharyngeal airway volumes. Transverse maxillary constriction with a high, deep palatal vault is a significant risk factor. Additionally, nasal obstruction and low tongue posture, with or without a short lingual frenulum, are identified as craniofacial risk factors for SDB development in children.</p><p><strong>Conclusion: </strong>Early diagnosis and intervention are critical in managing PSDB.
