Is ankyloglossia associated with obstructive sleep apnea? This article is part of the master's thesis of the Surgery Sciences Program at the Faculty of Medical Sciences of the State University of Campinas (UNICAMP).

HIGHLIGHTS

An untreated shortened lingual frenulum at birth is associated with sleep apnea.

A shortened lingual frenulum alters the craniofacial growth with respiratory consequences.

Lingual frenuloplasty associated with myofunctional therapy is effective in the treatment of snoring.

In addition to improved sleep, there was an improvement in the speech and deglutition functions.

Abstract

Objectives

To investigate the evidence on the association between ankyloglossia and obstructive sleep apnea.

Methods

An integrative literature review was carried out in the databases. Observational and interventional studies that assessed the lingual frenulum in children with sleep-disordered breathing were included. As exclusion criteria: studies in animals, in vitro, letters to the editor, expert opinions, other reviews. The selected articles were analyzed regarding the study design, sample, characterization of the lingual frenulum and sleep assessment, in addition to the main results and conclusions.

Results

Ninety-seven articles were identified, but only 4 met the inclusion criteria. Two retrospective studies concluded that the untreated shortened lingual frenulum at birth is associated with obstructive sleep apnea. A prospective study concluded that there was an improvement in speech and deglutition after lingual frenectomy, in addition to improved sleep. A retrospective cohort concluded that lingual frenuloplasty combined with myofunctional therapy is effective in the treatment of snoring and mouth breathing.

Conclusion

The studies included in this review contribute to corroborate the association between ankyloglossia and obstructive sleep apnea.
