This systematic review was conducted to assess if there are changes in gastroesophageal reflux (GER) outcomes after frenotomy in infants with ankyloglossia. Systematic Review. CINAHL, Cochrane, EMBASE, Pubmed, and Scopus were searched from inception to May 20, 2023. Inclusion criteria consisted of all study designs, infants ≤12 months of age with ankyloglossia, and use of quantitative GER measures (esophageal pH manometry (pH) or multi-channel intraluminal impedance (MII), and/or patient-reported symptom scores) pre- and post-frenotomy. Quality assessment and data extraction were performed in duplicate. Of 37 articles screened, 7 met inclusion criteria (6 prospective cohort studies and 1 RCT). No studies utilized objective measures to quantify reflux, that is MII or pH. The number of infants with ankyloglossia ranged from 47 to 237 (mean age of 4.4-8.3 weeks). Qualitative analysis included all 7 studies which used the GIGER, I-GERQ-R, and GSQ-I scales to assess GER. Parent-reported GER scores decreased post-frenotomy. However, the lack of control groups in the prospective cohort studies precludes conclusive findings that changes are related to frenotomy. Meta-analysis was not possible due to the high risk of bias from limited sample sizes, poor methodology, and lack of adequate control groups. Limited work has been conducted on the relationship between frenotomy and GER in infants with ankyloglossia. The lack of high-quality studies precludes definitive conclusions, as GER symptoms are known to improve spontaneously with time. Future RCT studies are warranted to further elucidate the effect of frenotomy on symptoms of GER in infants with ankyloglossia. III.
