Efficacy of rapid maxillary expansion in children with obstructive sleep apnea syndrome: 36 months of follow-up

Evaluation and management of pediatric obstructive sleep apnea beyond tonsillectomy and adenoidectomy

PURPOSE OF REVIEW

There is an increasing percentage of children with persistent obstructive sleep apnea (OSA) after removal of the tonsils and adenoids (T&A). Although sleep apnea has been an active area of research and treatment in the adult population, our awareness of this problem in children is still in its initial stages. In addition, therapies to successfully treat this residual OSA are still not fully established. It is important to develop evaluation and management protocols for these children.

RECENT FINDINGS

This review will discuss risk factors associated with persistent OSA after T&A and techniques to evaluate the pediatric airway in order to identify the site, or sites, of obstruction. Various medical and surgical options are presented.

SUMMARY

Clinicians need to be aware of the potential for persistent sleep disordered breathing and OSA in children, despite previous T&A. Evaluation protocols and techniques will differ in children, due to limitations in their cooperation during the physical examination. Alternative methods, such as airway endoscopy and cine MRI, are presented. Medical and surgical options are presented. Outcomes data for pediatric populations are rare. Multilevel, single stage surgery has a higher risk for oropharyngeal stenosis in children compared with adults and conservative, multistage approaches may be more appropriate.

Effectiveness and outcome of oral appliance therapy

Oral appliances (OAs) are a primary treatment option for snoring and mild to moderate obstructive sleep apnea (OSA) and are implemented as a noninvasive alternative for patients with severe OSA who are unwilling or unable to tolerate continuous positive airway pressure for the management of their disease. Studies have demonstrated the ability of OAs to eliminate or significantly reduce the symptoms of OSA and produce a measurable influence on the long-term health effects of the disease. Most studies have evaluated one type of OAs, the mandibular advancement splints. This article describes the effectiveness and outcomes of mandibular advancement splints.

Mandibular advancement devices are an alternative and valid treatment for pediatric obstructive sleep apnea syndrome

BACKGROUND

Orthodontic and craniofacial abnormalities have often been reported in pediatric sleep-disordered breathing (SDB). While the reversibility of these craniofacial abnormalities by means of adenotonsillectomy has yet to be established, orthodontic treatment based on oral appliances is considered to be a potential additional treatment for pediatric SDB.

DISCUSSION

Oral appliances may help improve upper airway patency during sleep by enlarging the upper airway and/or by decreasing upper airway collapsibility, thereby enhancing upper airway muscle tone. Orthodontic therapy should be encouraged in pediatric OSAS, and an early approach may permanently modify nasal breathing and respiration, thereby preventing obstruction of the upper airway.
