Review
AIM
Ankyloglossia is a common congenital malformation characterized by a short, thick, or tight tongue frenulum, and its effect on speech articulation remains controversial. This study aimed to evaluate (a) the association between ankyloglossia and speech disorders, and (b) the effectiveness of surgical interventions on the articulation of patients with ankyloglossia.
MATERIAL AND METHODS
A comprehensive search of PubMed was conducted. Randomized control trials (RCTs), cohort studies, case-control studies, and case series with more than five cases were included.
RESULT
Of the 16 included studies, except for one cross-sectional study, all studies were small in sample size. The evidence quality was generally low, with an average of 3.88 in a 7-point system. Three studies investigated the occurrence of speech disorders in the ankyloglossia population and obtained different results. Fifteen studies assessed the effectiveness of surgery, among which eight self-control studies observed significant postoperative improvement, whereas three of four cohort studies with untreated controls reported no significant differences. Three RCTs compared surgical techniques and one pointed out the advantage of frenuloplasty over frenulotomy.
CONCLUSION
There was no clear connection between ankyloglossia and speech disorders. More widely accepted uniform grading systems and well-designed clinical studies are needed.

Review
Ankyloglossia is a pathology of the tongue in which the frenulum appears anchored to the floor of the mouth. The treatment of choice for this pathology is frenectomy, but myofunctional therapy is emerging in recent years as a complement to surgical intervention. This systematic review aims to synthesize the scientific evidence and assess its quality regarding the use of myofunctional therapy in ankyloglossia. The Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, Pubmed, Web of Science and Scopus were searched. Study quality was determined using the PEDro scale, STROBE statement and single-case experimental design scale. Eleven studies were selected. Based on the studies included in this review, surgery is more effective than myofunctional therapy, although better results are achieved if both are combined. Improvements have been found in maternal pain, weight gain of babies, duration of breastfeeding, tongue mobility, strength and endurance, sleep apnea, mouth breathing and snoring, quality of life, clenching teeth, myofascial tension, pain after surgery and speech sound production. These findings must be taken with caution because of the small number of articles and their quality. Future clinical trials using larger sample sizes and with higher methodological quality are needed.

Meta-Analysis Review
AIM
To evaluate breastfeeding symptoms associated with ankyloglossia/tongue-tie.
METHODS
Databases included PubMed, Embase, CINAHL, PsycINFO, Web of Science, and Google Scholar. Eligible studies reported baseline breastfeeding symptoms/severity from tongue-tied infants. Two reviewers independently screened studies, extracted data, and assessed quality. Low-quality studies were excluded. Main outcomes were weighted mean severity scores for dyads with ankyloglossia relative to reference values for successful breastfeeding. Meta-analyses used inverse-variance-weighted random-effects models.
RESULTS
Of 1328 screened studies, 39 were included (5730 infants with ankyloglossia). The mean LATCH score for patients with untreated ankyloglossia, 7.1 (95% CI: 6.7-7.4), was significantly below the good-breastfeeding threshold. The mean Infant Breastfeeding Assessment Tool score, 10.0 (8.2-11.7), was not significantly below the good-breastfeeding threshold. The mean Infant-Gastroesophageal Reflux Questionnaire-Revised score, 18.2 (10.5-26.0), was consistent with gastroesophageal reflux disease. The mean Breastfeeding Self-Efficacy Scale-Short Form score, 43.7 (39.3-48.1), indicated significant risk of cessation of exclusive breastfeeding within 1-3 months. Mean nipple pain was 4.9 (4.1-5.7) on a 0-10 scale, greater than typical scores for breastfeeding mothers without nipple damage. Total prevalence of breastfeeding difficulties was 49.3% (95% CI: 47.3-51.4%). Early, undesired weaning occurred in 20.3% (18.5-22.2%) of cases before intervention.
CONCLUSION
Ankyloglossia is adversely associated with breastfeeding success and maternal well-being.

Meta-Analysis Review
AIM
Tongue tie is a common problem affecting breastfeeding due to poor infant latch and/or maternal pain. Evidence of whether treatment improves breastfeeding outcomes is conflicting. We conducted a systematic review and meta-analysis to examine the effectiveness of tongue-tie treatment on breastfeeding difficulties.
METHODS
We searched peer-reviewed and grey literature in MEDLINE (OVID), PubMed, CINAHL Plus, EMBASE and PsycINFO, from 01/1970 to 09/2019.
INCLUSION
randomised and non-randomised clinical trials, and quasi-experimental study designs, involving breastfeeding interventions for full-term singleton infants, using standardised measure of breastfeeding difficulty.
EXCLUSION
qualitative and purely observational studies, lacked operational definition of breastfeeding difficulty, lacked control/comparison group. We assessed risk of bias, summarised study quality and results and conducted meta-analysis using random effects modelling.
RESULTS
Six studies on tongue-tie division were included (4 randomised and 2 non-randomised). Meta-analysis of standardised mean differences in breastfeeding difficulty scores in four studies showed statistically significant differences in favour of frenotomy (Pooled SMD +2.12, CI:(0.17-4.08)p = 0.03). Similarly, a statistically significant difference in favour of frenotomy was observed for pain (Pooled SMD -1.68, 95% CI: (-2.87- -0.48).
CONCLUSION
Results support that infant frenotomy is effective for improving standardised scores on breastfeeding difficulty and maternal pain scales and could improve breastfeeding outcomes.

Meta-Analysis Review
BACKGROUND
Prevalence of ankyloglossia may vary depending on the assessment tool. This systematic review aimed to evaluate the prevalence of ankyloglossia in distinct age groups according to different assessment tools.
TYPES OF STUDIES REVIEWED
Nine electronic databases were searched from inception through November 2021 without restrictions of language or year of publication. Paired independent reviewers selected cross-sectional and cohort studies reporting the diagnosis of ankyloglossia, extracted data, and assessed methodological quality. The number of patients with ankyloglossia and the sample were extracted to calculate the overall prevalence of ankyloglossia and 95% CI. The authors calculated the prevalence of ankyloglossia per assessment tool, age group, and sex. They assessed the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach.
RESULTS
Seventy-one studies were included. Seven different diagnostic tools were used. The overall prevalence of ankyloglossia was 5% (95% CI, 4.0% to 5.0%) and ranged from 2% (using an unspecific tool) to 20% (Coryllos classification). The prevalence per age group was higher in infants (7%). The prevalence ratio was 1.34 (95% CI, 1.17 to 1.54) for boys, with very low certainty of evidence.
PRACTICAL IMPLICATIONS
The prevalence of ankyloglossia is higher among infants and differs depending on the assessment tool used for the diagnosis. It is uncertain whether boys are more affected by ankyloglossia than girls.

Review
It is unclear how effective tongue-tie classification assessment tools are in diagnosing symptomatic tongue-tie and fulfilling lingual frenectomy criteria. The purpose of this systematic review is to determine and evaluate any association between tongue-tie severity, as measured by pre-treatment assessment tools, and post-operative outcome following tongue-tie division. PubMed, EMBASE, and the Cochrane search engines were used to retrieve articles published between 1947 and 2021. Included studies consisted of patients with symptomatic tongue-tie, assessment by either the Coryllos, Kotlow, or Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) classification tool, and tongue-tie division. A total of 205 abstracts were identified; 31 studies met the criteria for a full-text review, of which, only 14 studies met the criteria for data extraction and analysis. Six studies used the HATLFF, 2 studies used the Kotlow, 5 studies used the Coryllos, and 1 study used a combination of both Kotlow and Coryllos methods. Significant heterogeneity was evident across all studies. No statistical correlation between the two variables could be determined. Although tongue-tie division procedures appear to provide benefits in breastfeeding and speech, there are no data to suggest a statistically significant association between the severity of tongue-tie, and the correct identification of patients who would benefit from tongue-tie division. © 2022 Australian Dental Association.

Review
OBJECTIVE
The purpose of this study was to evaluate the spectrum of pediatric quality-of-life sequelae associated with ankyloglossia that may affect children who do not undergo tongue-tie release (frenotomy) during infancy.
DATA SOURCES
This study contains data from PubMed, Embase, CINAHL, PsycINFO, Web of Science, and Google Scholar (1961-January 2023).
REVIEW METHOD
The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews reporting guidelines. Experimental and observational studies were eligible if they reported baseline outcomes associated with ankyloglossia in children above a year of age. Two reviewers independently screened studies, extracted data, and assessed quality. Low-quality studies were excluded.
CONCLUSIONS
Twenty-six of 1,568 screened studies (> 1,228 patients) were included. Six studies were high quality and 20 were medium quality. Studies identified various symptoms that may be partially attributable to ankyloglossia after infancy, including speech/articulation difficulties, eating difficulties, dysphagia, sleep-disordered breathing symptoms, dental malocclusion, and social embarrassment such as oral hygiene issues. Multiple comparative studies found associations between ankyloglossia and risk factors for obstructive sleep apnea; a randomized controlled trial found that frenotomy may attenuate apnea severity. Ankyloglossia may also promote dental crowding.
IMPLICATIONS FOR PRACTICE
Ankyloglossia may be associated with myriad effects on children's quality of life that extend beyond breastfeeding, but current data regarding the impact are inconclusive. This review provides a map of symptoms that providers may want to evaluate as we continue to debate the decision to proceed with frenotomy or nonsurgical therapies in children with ankyloglossia. A continuing need exists for controlled efficacy research on frenotomy for symptoms in older children and on possible longitudinal benefits of early frenotomy for maxillofacial development.

Meta-Analysis
BACKGROUND
Symptoms related to infant ankyloglossia/tongue-tie may deter mothers from breastfeeding, yet frenotomy is controversial.
METHODS
Databases included PubMed, Embase, CINAHL, PsycINFO, Web of Science, and Google Scholar from 1961-2023. Controlled trials and cohort studies with validated measures of surgical efficacy for breastfeeding outcomes were eligible. Meta-analyses synthesized data with inverse-variance weighting to determine standardized mean differences (SMD) between pre-/postoperative scores.
RESULTS
Twenty-one of 1568 screened studies were included. Breastfeeding self-efficacy improved significantly post-frenotomy: medium effect after 5-10 days (SMD 0.60 [95% CI: 0.48, 0.71; P < 0.001]), large effect after 1 month (SMD 0.91 [CI: 0.79, 1.04; P < 0.001]). Nipple pain decreased significantly post-frenotomy: large effect after 5-15 days (SMD -1.10 [CI: -1.49, -0.70; P < 0.001]) and 1 month (SMD -1.23 [CI: -1.79, -0.67; P = 0.002]). Frenotomy had a medium effect on infant gastroesophageal reflux severity at 1-week follow-up (SMD -0.63 [CI: -0.95, -0.31; P = 0.008]), with continued improvement at 1 month (SMD -0.41 [CI: -0.78, -0.05; P = 0.04]). From LATCH scores, breastfeeding quality improved after 5-7 days by a large SMD of 1.28 (CI: 0.56, 2.00; P = 0.01).
CONCLUSIONS
Providers should offer frenotomy to improve outcomes in dyads with ankyloglossia-associated breastfeeding difficulties.
PROTOCOL REGISTRATION
PROSPERO identifier CRD42022303838 .
IMPACT
This systematic review and meta-analysis showed that breastfeeding self-efficacy, maternal pain, infant latch, and infant gastroesophageal reflux significantly improve after frenotomy in mother-infant dyads with breastfeeding difficulties and ankyloglossia. Providers should offer frenotomy to improve breastfeeding outcomes in symptomatic mother-infant dyads who face challenges associated with ankyloglossia.

Meta-Analysis Review
BACKGROUND
Tongue-tie, or ankyloglossia, is a condition whereby the lingual frenulum attaches near the tip of the tongue and may be short, tight and thick. Tongue-tie is present in 4% to 11% of newborns. Tongue-tie has been cited as a cause of poor breastfeeding and maternal nipple pain. Frenotomy, which is commonly performed, may correct the restriction to tongue movement and allow more effective breastfeeding with less maternal nipple pain.
OBJECTIVES
To determine whether frenotomy is safe and effective in improving ability to feed orally among infants younger than three months of age with tongue-tie (and problems feeding).Also, to perform subgroup analysis to determine the following.• Severity of tongue-tie before frenotomy as measured by a validated tool (e.g. Hazelbaker Assessment Tool for Lingual Frenulum Function (ATLFF) scores < 11; scores ≥ 11) (Hazelbaker 1993).• Gestational age at birth (< 37 weeks' gestation; 37 weeks' gestation and above).• Method of feeding (breast or bottle).• Age at frenotomy (≤ 10 days of age; > 10 days to three months of age).• Severity of feeding difficulty (infants with feeding difficulty affecting weight gain (as assessed by infant's not regaining birth weight by day 14 or falling off centiles); infants with symptomatic feeding difficulty but thriving (greater than birth weight by day 14 and tracking centiles).
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and CINAHL up to January 2017, as well as previous reviews including cross-references, expert informants and journal handsearching. We searched clinical trials databases for ongoing and recently completed trials. We applied no language restrictions.
SELECTION CRITERIA
Randomised, quasi-randomised controlled trials or cluster-randomised trials that compared frenotomy versus no frenotomy or frenotomy versus sham procedure in newborn infants.
DATA COLLECTION AND ANALYSIS
Review authors extracted from the reports of clinical trials data regarding clinical outcomes including infant feeding, maternal nipple pain, duration of breastfeeding, cessation of breastfeeding, infant pain, excessive bleeding, infection at the site of frenotomy, ulceration at the site of frenotomy, damage to the tongue and/or submandibular ducts and recurrence of tongue-tie. We used the GRADE approach to assess the quality of evidence.
MAIN RESULTS
Five randomised trials met our inclusion criteria (n = 302). Three studies objectively measured infant breastfeeding using standardised assessment tools. Pooled analysis of two studies (n = 155) showed no change on a 10-point feeding scale following frenotomy (mean difference (MD) -0.1, 95% confidence interval (CI) -0.6 to 0.5 units on a 10-point feeding scale). A third study (n = 58) showed objective improvement on a 12-point feeding scale (MD 3.5, 95% CI 3.1 to 4.0 units of a 12-point feeding scale). Four studies objectively assessed maternal pain. Pooled analysis of three studies (n = 212) based on a 10-point pain scale showed a reduction in maternal pain scores following frenotomy (MD -0.7, 95% CI -1.4 to -0.1 units on a 10-point pain scale). A fourth study (n = 58) also showed a reduction in pain scores on a 50-point pain scale (MD -8.6, 95% CI -9.4 to -7.8 units on a 50-point pain scale). All studies reported no adverse effects following frenotomy. These studies had serious methodological shortcomings. They included small sample sizes, and only two studies blinded both mothers and assessors; one did not attempt blinding for mothers nor for assessors. All studies offered frenotomy to controls, and most controls underwent the procedure, suggesting lack of equipoise. No study was able to report whether frenotomy led to long-term successful breastfeeding.
AUTHORS' CONCLUSIONS
Frenotomy reduced breastfeeding mothers' nipple pain in the short term. Investigators did not find a consistent positive effect on infant breastfeeding. Researchers reported no serious complications, but the total number of infants studied was small. The small number of trials along with methodological shortcomings limits the certainty of these findings. Further randomised controlled trials of high methodological quality are necessary to determine the effects of frenotomy.

Meta-Analysis Review
BACKGROUND
Ankyloglossia is a congenital alteration that affects the tongue's mobility, influencing craniofacial development; however, its association with malocclusion is still unclear. This systematic review and meta-analysis investigated the association between ankyloglossia and malocclusion in patients.
TYPES OF STUDIES REVIEWED
The authors conducted a systematic review and meta-analysis of observational studies that investigated the association between malocclusion and the presence of ankyloglossia in any age group, used any assessment tool to diagnose ankyloglossia, and considered all types of malocclusion. The authors conducted searches in 8 electronic databases through July 1, 2022. They used Joanna Briggs Institute appraisal tools to assess the methodological quality and the Grading of Recommendations, Assessment, Development and Evaluations approach to assess the certainty of the evidence.
RESULTS
Eleven studies (5 cross-sectional, 6 case-control) included 2,904 patients and over 13 occlusal alterations. The certainty of the evidence ranged from low through very low. Patients with Angle Class III malocclusion had similar or more inserted lingual frenula than patients with Class I malocclusion (standard mean difference, 0.37; 95% CI, -0.50 to 1.25) and Class II malocclusion (standard mean difference, 0.55; 95% CI, -0.52 to 1.63). Patients with Class III malocclusion had clinically significant increased mouth opening reduction compared with patients with Class I malocclusion (mean difference, 6.67; 95% CI, 4.01 to 9.33) and Class II malocclusion (mean difference, 5.04; 95% CI, 2.35 to 7.72) patients.
PRACTICAL IMPLICATIONS
There is uncertain evidence that ankyloglossia may be associated with the development of occlusal alterations. Ankyloglossia did not influence the Angle classification. Clinicians should closely follow children with ankyloglossia to evaluate whether this condition interferes with the occlusion. Future research should prospectively follow up on the long-term association between ankyloglossia and malocclusion. The protocol was registered a priori in the PROSPERO database (CRD42021248034). No amendments were deemed necessary after the registration of the protocol. Some subgroup analyses planned a priori were not possible, such as the severity of ankyloglossia, sex, and age, due to the lack of studies reporting data for these subgroups.
