ABSTRACT
Objective: To evaluate outcomes of the surgical and rehabilitative procedures devoted to release the tongue-tie in non-infants when implementing the most commonly used quantitative/qualitative structured tools for tongue and frenulum assessment. Methods: A scoping review and meta-analysis were conducted following the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis extension for scoping reviews. Results: The systematic search retrieved 603 (Pubmed), 893 (Scopus), and 739 (ISI Web of Science) articles from January 2011 to December 2021. A total of 50 articles were retrieved for full-text review of which 7 were selected and included based on inclusion criteria. The majority of treatment options have been found to significantly improve the anatomical limitation of the tongue with clear benefits on descending functionality. Conclusions: The review highlights an overall improvement in terms of clinical and functional outcomes when using validated tongue assessment tools both before and after frenulum release. This highlights the need for their rigorous implementation in research and clinical practice.
