Ankyloglossia and Breastfeeding Duration: A Multicenter Birth Cohort Study.

Background and Objective: The prevalence of ankyloglossia and its impact on breastfeeding practices may be overestimated, leading to surgical overtreatment in newborns. The study was conducted to estimate the prevalence of ankyloglossia in the first year of life and investigate the association with exclusive and total breastfeeding duration in different regions of Brazil. Materials and Methods: This multicenter prospective cohort study involved the recruitment of mother-infant pairs soon after childbirth in public hospitals in three state capitals in Brazil. Interviews were held with the mothers after birth, at 6 and 12 months to collect sociodemographic variables and data on exclusive and total breastfeeding duration. At 12 months of age, the children were submitted to a dental examination for classification of the lingual frenulum using the Bristol Tongue Assessment Tool. Data analysis involved Poisson regression with robust variance, with the calculation of unadjusted and adjusted relative risk (RR). Results: The final sample was composed of 293 children. The prevalence of defined and suspected ankyloglossia was 1% and 4.8%, respectively, totaling 5.8% (confidence interval [95% CI]: 3.1-8.5). No significant difference was found in the prevalence of exclusive and total breastfeeding at 1, 4, and 6 months between children with defined/suspected ankyloglossia and those without ankyloglossia. The multivariable analysis showed that the probability of the child achieving 6 months of breastfeeding did not differ between groups (RR = 0.98; 95% CI: 0.79-1.23; p = 0.907). Conclusion: The prevalence of defined ankyloglossia was very low and defined/suspected ankyloglossia was not associated with exclusive or total breastfeeding duration. Clinical Trial Registration: Registered with clinicaltrials.gov (n° NCT03841123).

The development of a specialist tongue tie assessment clinic for neonates.

OBJECTIVES: Ankyloglossia or tongue tie is a condition where the lingual frenulum restricts tongue movement, negatively impacting breastfeeding. An increasing number of infants diagnosed with ankyloglossia may lead to unnecessary procedures. To limit the overtreatment of this problem, we established a specialist clinic to provide the best available evidence-based care to the mother-infant dyad. METHODS: We discuss the development of a specialist tongue tie assessment clinic in our unit. RESULTS: From January to October 2023, there were 162 visits to the clinic by 157 patients. During this time, there were 96 frenotomies performed. CONCLUSIONS: The mother-infant dyad is a vulnerable patient group. Establishing a specialist tongue tie assessment clinic with otolaryngology and lactation expertise provides the best available evidence-based care.

Caso clínico: Se presenta un paciente varón de 6 años diagnosticado de anquiloglosia severa que acude por dificultad en la pronunciación del fonema “RR”. Se realiza el tratamiento quirúrgico del frenillo mediante electrobisturí y su seguimiento por un logopeda. Conclusiones: El diagnóstico de la patología y la planificación quirúrgica y miofuncional deben tener en cuenta la clasificación del frenillo, la edad del paciente y la anatomía de la región. El tratamiento de la patología asociada al frenillo lingual corto requiere de un equipo multidisciplinar para evitar la recidiva. (AU)

Introduction: The short lingual frenulum can cause breastfeeding difficulties during the first months of life in the neonate. From language development they can be the cause of inadequate phonetics. Surgical treatment of the frenulum must be accompanied by adequate multidisciplinary treatment to improve the correction of pronunciation difficulties. The objective of this article is to present a representative clinical case of the diagnosis, surgical treatment and myofunctional rehabilitation of the short lingual frenulum, as well as to update the available scientific evidence. Case Report: A 6-year-old male patient is presented, diagnosed with severe ankyloglossia who came due to difficulty in pronouncing the phoneme “RR”. Surgical treatment of the frenulum was performed using electrocautery and its follow-up by a speech therapist. Conclusions: The diagnosis of the pathology and the surgical and myofunctional planning must take into account the classification of the frenulum, the age of the patient and the anatomy of the region. The treatment of the pathology associated with short lingual frenulum requires a multidisciplinary team to avoid recurrence. (AU)

Ankyloglossia: Typical Characteristics, Effects on Function, and Clinical Implications.

The purpose of this article is to (1) define the diagnostic characteristics of ankyloglossia, (2) identify potential problems associated with ankyloglossia, and (3) discuss treatment options, when treatment is appropriate. This article is based on a review of the literature, including recent systematic reviews, and the author's experience as a cleft and orofacial specialist. Ankyloglossia is a common congenital condition characterized by an anterior attachment of the lingual frenulum on the tongue. This causes difficulty elevating and/or protruding the tongue tip. As such, ankyloglossia has been thought to affect neonatal feeding, speech, and other functions. Although systematic reviews have concluded that most infants with ankyloglossia can be fed normally, a small percentage of affected infants will show improved efficiency of feeding post-frenotomy. They also concluded that frenotomy may relieve nipple pain in the breastfeeding mothers of affected infants. Regarding speech, the systematic reviews concluded that there is no evidence that ankyloglossia causes speech disorders. This may be because simple compensations will result in normal acoustics of the sounds. Therefore, frenotomy should be recommended sparingly for newborn infants, and it should rarely, if ever, be recommended for speech disorders.

The effect of frenectomy for tongue-tie, lip-tie, or cheek-tie on breastfeeding outcomes: A systematic review of articles over time and suggestions for management.

OBJECTIVE: Tongue-tie, or ankyloglossia, is a common condition characterized by an abnormally short or tight lingual frenulum and is known to cause breastfeeding difficulties, leading to damage to the nipple, early discontinuation of breastfeeding, and delayed infant growth. In addition to tongue-tie, abnormal frenulums such as the labial frenulum and buccal frenulum can cause lip-tie and cheek-tie, respectively. While both of these conditions have been reported to potentially cause similar issues related to breastfeeding as tongue-tie, limited research has been conducted to understand their effects and how we should treat these conditions. METHODS: In this systematic review, we conducted a comprehensive search of MEDLINE to analyze the trend in publications of all three of these conditions and their impact on breastfeeding for the past 36 years. Keywords included, "tongue-tie", "lip-tie", "cheek-tie", and "breastfeeding outcomes". RESULTS: We found that publications describing the effect of only tongue-ties on breastfeeding have increased exponentially over time while less focus has been on other oral ties. It was also discovered that the majority of studies describing only lip-tie or tongue-tie were editorials, commentary, perspectives, or consensus statements. Finally, we found that articles describing more than one abnormal frenulum were more likely to be cited and articles describing tongue-tie only were published in the highest impact factor journals. CONCLUSION: This study revealed a significant increase in publications discussing tongue-tie and a lack of research on lip-tie and cheek-tie in relation to breastfeeding. The findings highlight the need for more comprehensive research and attention to lip-tie and cheek-tie, as well as standardized diagnostic criteria. Ongoing debate surrounding management of these conditions stem from the lack of investigations on the impact of these abnormal frenulums and outcomes post-frenectomy. Future high-quality studies, specifically prospective cohort studies and randomized controlled trials, are necessary to provide more robust evidence and guide clinical practice.

Ankyloglossia: Clinical and Sociodemographic Predictors of Diagnosis and Management in the United States, 2004 to 2019.

OBJECTIVE: The past 2 decades have seen a rapid increase in the diagnosis of ankyloglossia. Patients are often managed by lingual frenotomy. The objective is to define the clinical and socioeconomic factors that determine which patients receive frenotomy. STUDY DESIGN: A retrospective analysis of commercially insured children. SETTING: Optum Data Mart database. METHODS: Trends in frenotomy including provider and setting were described. Multiple logistic regression was used to determine predictors of frenotomy. RESULTS: Diagnosis of ankyloglossia increased from 2004 to 2019 (from 3377 in 2004 to 13,200 in 2019), while lingual frenotomy similarly increased from 1483 in 2004 to 6213 in 2019. The proportion of inpatient frenotomy procedures increased from 6.2% to 16.6% from 2004 to 2019, with pediatricians having the highest odds of performing inpatient frenotomies (odds ratio: 4.32, 95% confidence interval: 4.08, 4.57). Additionally, during the study period, the proportion of frenotomies performed by pediatricians increased from 13.01% in 2004 to 28.38% in 2019. In multivariate regression analyses, frenotomy was significantly associated with the male sex, white non-Hispanic ethnicity, higher parental income and education, and a greater number of siblings. CONCLUSION: Ankyloglossia has been increasingly diagnosed in the past 2 decades, and among patients with ankyloglossia, frenotomy is increasingly performed. This trend was driven at least in part due to increasing rates of pediatricians as proceduralists. After accounting for maternal and patient-level clinical factors, socioeconomic differences in the management of ankyloglossia were observed.

Anquiloglossia em bebês: da embriologia ao tratamento - uma revisão de literatura / Ankyloglossia in babies: from embryology to treatment - a literature review

Objetivo: o objetivo do presente estudo foi realizar uma revisão narrativa de literatura sobre a anquiloglossia em bebês, apresentando os critérios para diagnóstico, implicações na amamentação e formas de tratamentos. Fontes dos dados: foram realizadas, em abril de 2022, buscas nas bases de dados PubMed e Scielo, considerando artigos publicados entre os anos 1990 e 2022. Foram utilizadas como palavras-chave: frenectomy; babies; ankyloglossia; breastfeeding. A seleção dos trabalhos foi realizada através da leitura dos títulos e dos resumos. Após a aplicação dos critérios de inclusão e exclusão, 27 artigos foram selecionados, sendo eles pesquisas originais, relatos de caso e revisões de literatura. Livros textos nacionais também foram utilizados. Síntese dos dados: apesar de não existir um teste para diagnóstico considerado padrão-ouro, a triagem neonatal para investigação de anquiloglossia é uma obrigatoriedade nas maternidades de todo o país. Os testes para diagnóstico mais utilizados no Brasil são "Teste da Linguinha" e de Bristol. Não foram encontradas evidências científicas que relacionem a frenotomia e/ou frenectomia à melhora da amamentação. A abordagem multidisciplinar abrangendo dentistas, fonoaudiólogos, pediatras, consultores de amamentação, otorrinolaringologistas, cirurgiões e outros profissionais capacitados, deve ser considerada para delinear a melhor conduta clínica. Dentre as técnicas cirúrgicas, a frenotomia em bebês mostra-se como sendo a mais segura por apresentar menos riscos de complicações transoperatórios e pós-cirúrgica. Conclusão: faz-se necessário a realização de estudos controlados e com baixo viés metodológico sobre diagnóstico, tratamento e impactos da anquiloglossia na amamentação para padronizar e nortear a conduta clínica da equipe multidisciplinar responsável pelo binômio mãe-bebê no período puerperal.

Objective: the aim was to conduct a narrative literature review on ankyloglossia in infants, presenting the criteria for diagnosis, implications on breastfeeding, and treatment options. Sources of data: a search was conducted in PubMed and Scielo databases, considering articles published between 1990 and 2022 in April 2022. The key words used were: frenectomy; babies; ankyloglossia; breastfeeding. The selection of the papers was made through the title and by reading the abstracts. After applying the inclusion and exclusion criteria, 27 articles were selected, which were original research, case reports and literature reviews. National textbooks were also used. Synthesis of data: there is no test for diagnosis considered gold standard, neonatal screening for ankyloglossia investigation is a mandatory in maternity hospitals all over the country. The most used diagnostic tests in Brazil are the "Martinelli Test" and the "Bristol test". No scientific evidence was found relating frenotomy and/or frenectomy to improve breastfeeding. A multidisciplinary approach including dentists, speech therapists, pediatricians, breastfeeding consultants, otorhinolaryngologists, surgeons, and other trained professionals must be considered to outline the best clinical management. Among the surgical techniques, frenotomy in infants is the safest because it presents fewer risks of transoperative and post-surgical complications. Conclusion: it is necessary to carry out controlled studies with low methodological bias on diagnosis, treatment, and the impact of ankyloglossia on breastfeeding, to standardize and guide the clinical management of the multidisciplinary team responsible for the mother-baby binomial during the puerperal period.

Prevalence of ankyloglossia according to different assessment tools: A meta-analysis.

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.

Effectiveness of tongue-tie assessment tools in diagnosing and fulfilling lingual frenectomy criteria: a systematic 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.

Complications and misdiagnoses associated with infant frenotomy: results of a healthcare professional survey.

BACKGROUND: In the past 10-15 years, there has been increased concern about ankyloglossia and its effect on infant breastfeeding. This has been associated with increased performance of frenotomy. Physicians and other healthcare professionals with expertise in breastfeeding have voiced concerns about complications related to the performance of infant frenotomy. Reviews of this topic have reported no significant complications after frenotomy. Other data on complications consist of case reports. METHODS: An online survey was developed by physicians with expertise in breastfeeding and e-mailed to physician and dentist members of Academy of Breastfeeding Medicine (ABM) between 11 November and 31 December 2019. It requested information from the respondents who cared for the mother/infant breastfeeding couple about their experiences personally caring for infants with complications or misdiagnoses related to referral for frenotomy or the performance of a frenotomy. Data were analyzed using chi square, Cramer's V correlation, and binomial logistic regression. RESULTS: Of 211 eligible respondents, 129 (61%) had cared for an infant with a complication or misdiagnosis. Two hundred and nine (209) infants were reported to have a complication and 237 had a misdiagnosis. The most common misdiagnoses reported were 101 of 237 infants (43%) with neuromuscular dysfunction and 65 of 237 (27%) with inadequate breastfeeding support. The most common complications reported were a repeat procedure considered/requested/performed 65 of 203 (32%) and oral aversion 57 of 203 (28%). Parental report of infant pain was associated with performance of a posterior frenotomy (Chi Square p < .003). Bleeding was associated with using scissors/scalpel vs laser/bovie/electrosurgery (Chi Square p = .001). Oral aversion was associated with performance of frenotomy by laser/bovie/electrosurgery vs scissors/scalpel (adjusted Odds Ratio of 4.05; 95% CI 2.07, 7.93). CONCLUSIONS: Complications and misdiagnoses are occurring after infant frenotomy. Physicians and dentists should work closely with lactation professionals to provide skilled breastfeeding support and to evaluate for other confounding problems that might impact infant breastfeeding before referral for frenotomy. Randomized controlled trials of optimized lactation support vs. frenotomy and of scissors vs laser in performance of frenotomy are needed.

Relationship between short lingual frenulum and malocclusion. A multicentre study

Objective: Ankyloglossia is characterized by an abnormally short lingual frenulum, which impairs tongue movement. Ankyloglossia has been related to craniofacial growth disturbances and dental malocclusion. But even though there is a clear biological plausibility for this hypothesis, available evidence is scarce. Methods: A case–control design was followed. Patients between 4 and 14 years old were routinely screened for short lingual frenulum and recruited from the pediatric Otolaryngology consultation of 3 Spanish tertiary referral hospitals. Lingual frenulum was assessed with the Marchesan system. A cohort of cases with short lingual frenulum and a cohort of healthy controls matched for sex and age were included. Both cases and controls had pictures of occlusion. Occlusion was evaluated by an expert in orthodontics, blinded for the frenulum assessment. Results: A total of 100 participants were included, 70 males and 30 females. The proportion of malocclusion in the short lingual frenulum group was 48%, while it was 24% in the normal frenulum group. The odds ratio of malocclusion for the short lingual frenulum patients was 2.92 (CI 95% 1.15–7.56). The difference was statistically significant (p=.012). This difference was significant for patients with class III occlusion (p=.029). There was no difference for patients with class II (p=.317). Conclusions: This work supports the hypothesis that relates class III malocclusion with a short lingual frenulum.(AU)

Objetivo: La anquiloglosia se caracteriza por un frenillo lingual anormalmente corto que dificulta la movilidad de la lengua. La anquiloglosia ha sido relacionada con alteraciones del desarrollo facial y maloclusión dentaria. Sin embargo, a pesar de una clara plausibilidad biológica para esta hipótesis, la evidencia disponible es escasa. Métodos: Siguiendo un diseño de casos y controles se incluyeron pacientes entre 4-14 años atendidos en las consultas de otorrinolaringología pediátrica de 3 hospitales de tercer nivel en España. El frenillo lingual se evaluó mediante el sistema de Marchesan. Se incluyó una cohorte de casos con frenillo lingual corto, y una cohorte de controles sanos apareados por sexo y edad. A todos los participantes se les tomó fotografía dentaria en oclusión. La oclusión se evaluó mediante un odontólogo experto en ortodoncia, ciego a la evaluación del frenillo lingual. Resultados: Se incluyeron un total de 100 participantes, 70 hombres y 30 mujeres. La proporción de maloclusión en la cohorte con frenillo lingual corto fue del 48% y del 24% en la cohorte de controles. La odds ratio de maloclusión fue 2,92 (IC 95%: 1,15-7,56). La diferencia entre grupos fue estadísticamente significativa (p=0,012). Por subgrupos, la diferencia fue estadísticamente significativa para los pacientes con maloclusión clase iii (p=0,029), pero no para aquellos con maloclusión clase ii (p=0,317). Conclusiones: Este trabajo apoya la hipótesis que relaciona la maloclusión de clase iii con el frenillo lingual corto.(AU)

Comparison Between Two Protocols for Ankyloglossia Diagnosis in Newborn Babies.

Purpose: Ankyloglossia is a congenital anomaly that restricts tongue movements and can interfere in breastfeeding. The purpose of this study was to compare two protocols for ankyloglossia diagnosis: (1) the Neonatal Tongue Screening Test (NTST); and (2) the Bristol Tongue Assessment Tool (BTAT). Methods: This was a cohort study involving live births at the University Hospital of Brasilia, Brasilia, Brazil, from August 2017 to July 2018. The gathered data were based on clinical examinations and interviews with mothers. The Stata software program was applied to conduct the analyses using the chi-square test, Spearman's correlation and the receiver operating characteristic (ROC) curve, and sensitivity, specificity, and positive and negative predictive values. Results: A total of 972 mother-baby dyads were evaluated. The protocols showed agreement (P ≤ 0.001) for an ankyloglossia diagnosis, according to Spearman's correlation. The prevalence of ankyloglossia was 5.5 percent (NTST) and 5.1 percent (BTAT) and was greater in the male gender in both protocols. According to the ROC curve, the four cutoff point showed better sensitivity and specificity (98.4 percent and 64.2 percent, respectively). The BTAT was highly accurate in comparison with the NTST. Conclusions: Both protocols showed similar low ankyloglossia prevalence. The Bristol Tongue Assessment Tool protocol is potentially more viable as a screening instrument than the Neonatal Tongue Screening Test protocol because it is simpler and more concise.

Tongue-Tie children with a severe Hazelbaker score or difficult breastfeeding greatly benefit from frenotomy or frenuloplasty with/without anaesthesia - First do or do no harm?

Tongue-tie (ankyloglossia) is a relatively common congenital anomaly characterised by an abnormally short lingual fraenulum, causing limitation of tongue mobility. There have been immense controversies regarding diagnosis, clinical significance and management of such condition hitherto. Although most tongue-tie babies are asymptomatic without feeding difficulties, operative corrections may be necessary in some cases to improve their breastfeeding. Using a meta-narrative reviewing study design, the aim of this concise review was to demonstrate the current evidences for surgical indications, optimal type and timing, and functional improvement from tongue-tie surgery. We reviewed and discussed the included evidences based on five topics: (1) basic sciences, (2) clinical equipoise, (3) anaesthesia during childhood, (4) evidence-based practice and surgical meta-analyses, and (5) appropriate patient assessment in routine paediatric practice.

Anquiloglosia en el lactante amamantado. Puesta al día / Ankyloglossia in breastfeeding infants. An update

El frenillo lingual corto, o anquiloglosia, puede generar problemas durante la lactancia con repercusión en el desarrollo del lactante, daño en el pezón de la madre y abandono precoz de la lactancia. Actualmente no existe homogeneidad en los criterios diagnósticos, lo que ocasiona tanto sobrediagnóstico como infradiagnóstico de esta alteración, con las consecuencias clínicas que ello conlleva. La dificultad en el abordaje radica en saber cuándo se trata de variantes anatómicas normales o de un frenillo lingual sin repercusión funcional, y cuándo los problemas de lactancia, que clásicamente se le atribuyen se deben realmente al frenillo. Alrededor del 50 % de los niños con frenillo lingual corto no presenta problemas de lactancia o estos se resuelven con apoyo y asesoramiento. En el resto de casos se puede recurrir a tratamiento quirúrgico. En este artículo se ha realizado una actualización de la clasificación y tratamiento de la anquiloglosia que permitirá a los profesionales un manejo adecuado de estos pacientes

Short frenulum, or ankyloglossia, may lead to breastfeeding problems, with an impact on infant development, nipple damage, and early abandonment of breastfeeding. There are currently no homogeneous diagnostic criteria, thus leading to both overdiagnosis and underdiagnosis and associated clinical consequences. The challenge to approach this condition lies in establishing whether it is a normal anatomical variation or a lingual frenulum without a functional impact and when breastfeeding difficulties which are typically attributed to it are actually caused by the frenulum. Approximately 50 % of ankyloglossia cases do not result in breastfeeding problems or these can be resolved with support and advice. Surgery may be proposed for the rest of the cases. This article offers an update on the classification and treatment of ankyloglossia, which will help health care providers to provide an adequate management to these patients

Upper Lip Tie: Anatomy, Effect on Breastfeeding, and Correlation With Ankyloglossia.

OBJECTIVES: There is debate among otolaryngologists and other practitioners about whether upper lip tie contributes to difficulty with breastfeeding and whether upper lip tie and ankyloglossia are linked. Our objectives were to evaluate the anatomy of the upper lip (maxillary) frenulum, to determine if the visual anatomy of the upper lip has an effect on breastfeeding, and to determine whether the occurrence of lip tie and tongue tie are correlated. METHODS: A prospective cohort study of 100 healthy newborns was examined between day of life 3-7. Surveys were completed by the mother at the time of the initial exam and 2 weeks later. The maxillary frenulum was graded based on the Stanford and Kotlow classifications by two independent reviewers. Inter-rater reliability and relationships between tongue tie, lip tie, and the infant breastfeeding assessment tool (IBFAT) were calculated. RESULTS: Inter-rater reliability showed fair agreement (κ = 0.302) using the Kotlow scale and better agreement using the Stanford classification (κ = 0.458). There was no correlation between the upper lip tie classification and breastfeeding success score. Lastly, there was a modest inverse correlation in the degree of tethering for the tongue and lip. CONCLUSIONS: There was no correlation between maxillary frenulum grade and comfort with breastfeeding, pain scores, or latch. There was also no relationship between tip to frenulum length (tongue tie) and visualized lip anatomy, suggesting that tongue tie and lip tie may not cluster together in infants.
