A multifaceted programme to reduce the rate of tongue-tie release surgery in newborn infants: Observational study

Posterior tongue tie: that is a thing?

PURPOSE OF REVIEW

The purpose of this review is to examine the current research of the posterior tongue tie and how it relates to breast feeding, solid feeding, and speech.

RECENT FINDINGS

Recent findings show that the posterior tongue tie may play a role in effective breast feeding.

SUMMARY

Ankyloglossia is the term used for the restriction of the movement of the tongue that impairs certain functions such as breastfeeding or bottle feeding, feeding with solids, and speech. Cadaver studies have shown that there can be a restriction of the tongue and oral tissues in some people relative to others. In some breast-feeding studies, releasing the posterior tie has been shown to improve certain aspects of tongue movement. There is little evidence for or against posterior tongue ties contributing to other problems such as speech and solid feeding. This article goes into depth about the current studies on posterior ankyloglossia.

Identification and Management of Ankyloglossia and Its Effect on Breastfeeding in Infants: Clinical Report

Ankyloglossia refers to a congenitally tight lingual frenulum that limits the motion of the tongue. Whether the release of a tight lingual frenulum in neonates improves breastfeeding is not clear. Because many of the symptoms of ankyloglossia overlap those of other breastfeeding difficulties, a team partnership is necessary.

Oral Structural Dysphagia in Children

Oral causes of dysphagia in infancy may involve the lips, the tongue, or the palate. Whereas ankyloglossia is commonly diagnosed in infants with dysphagia, assessment of the need for surgical intervention may be less straightforward. Tongue size (macroglossia) may be associated with dysphagia as it may cause limitation of movement of the food or milk bolus by the lips or cheeks. Congenital conditions such as cleft lip and palate, micrognathia, or craniofacial microsomia may also be associated with dysphagia. Diagnosis and treatment of these conditions can be improved with the engagement of lactation and feeding experts as well as multidisciplinary craniofacial teams.

A cross-sectional study of breastfed infants referred for tongue tie assessment and frenotomy in one Canadian health region

Importance

Tongue tie (TT) is a condition that can cause infant feeding difficulties due to restricted tongue movement. When TT presents as a significant barrier to breastfeeding, a frenotomy may be recommended. Universally accepted diagnostic criteria for TT are lacking and wide prevalence estimates are reported. New referral processes and a Frenotomy Assessment Tool were implemented in one Canadian health region to connect breastfeeding dyads with a provider for TT evaluation and frenotomy.

Objective

To determine the proportion of babies with TT as well as the frequency of frenotomy.

Methods

This cross-sectional study included infants who initiated breastfeeding at birth and were referred for TT evaluation over a 14-month period. Data were collected retrospectively by chart review and analyzed using SPSS. Factors associated with frenotomy were examined using logistic regression.

Results

Two hundred and forty-one babies were referred. Ninety-two percent (n = 222) were diagnosed with TT and 66.0% (n = 159) underwent frenotomy. In the multivariate model, nipple pain/trauma, inability to latch, inability to elevate tongue, and dimpling of tongue on extension were associated with frenotomy (P < 0.05). Most referrals in our region resulted in a diagnosis of TT; however, the number of referrals was lower than expected, and of these two-thirds underwent frenotomy.

Interpretation

TT is a relatively common finding among breastfed infants. Future research should examine whether a simplified assessment tool containing the four items associated with frenotomy in our multivariate model can identify breastfed infants with TT who require frenotomy.

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.

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.

Ankyloglossia in Central Australia: Prevalence, identification and management in infants

PURPOSE

To investigate the prevalence and management of ankyloglossia for infants in Central Australia.

METHOD

Retrospective chart review consisting of a medical file audit of infants (n = 493) <2 years old diagnosed with ankyloglossia from January 2013 to December 2018 in the primary hospital in Central Australia. Patient characteristics, reason for diagnosis, reason for procedure and outcomes of procedures routinely recorded in the patient clinical files were recorded.

RESULTS

The overall prevalence of ankyloglossia in this population was 10.2%. Frenotomy was performed in 97.9% of infants diagnosed with ankyloglossia. Infants with ankyloglossia were more likely to be male (58% vs 42%), diagnosed and managed with a frenotomy on the third day of life. Most ankyloglossia diagnoses were identified by a midwife (>92%). Most frenotomy procedures were completed by lactation consultants who were also midwives (99%) using blunt-ended scissors. More infants were classified with posterior ankyloglossia than anterior ankyloglossia (23% vs 15%). A frenotomy procedure resolved feeding issues in 54% of infants with ankyloglossia.

CONCLUSIONS

The prevalence of ankyloglossia and rate of frenotomy procedures were high when compared to previous reports in the general population. Frenotomy for ankyloglossia in infants with breastfeeding difficulties was found to be effective in more than half of the reported sample, improving breastfeeding and decreasing maternal nipple pain. A standardised approach and validated screening or comprehensive assessment tool for the identification of ankyloglossia is indicated. Guidelines and training for relevant health professionals on non-surgical management of the functional limitations of ankyloglossia are also recommended.

TikTok Influence on Rates of Tonsillectomies for Tonsil Stones

INTRODUCTION

Tonsillectomy is one of the most common otolaryngologic surgeries and is increasingly being performed for the management of tonsil stones or tonsilloliths. Incidentally, over the years, tonsilloliths have become a popular topic on the social media platform TikTok (ByteDance, Beijing, China) and we propose that this may be influencing the trends of tonsillectomies for tonsil stones.  Objectives: We aim to assess rates of outpatient visits and tonsillectomies for tonsil stones at our institution as well as analyze videos on TikTok regarding tonsil stones.

METHODS

A retrospective chart query was performed. Data including the number of patient encounters per month with a diagnosis code of tonsilloliths were collected from July 2016 to December 2021. The number of TikTok videos under the search result "tonsil stones" and the content of these videos were reviewed.

RESULTS

There were 126 patients seeking evaluation for tonsil stones with an average age of 33.4 years, and 76% were females. The number of patients who underwent a tonsillectomy for tonsil stones increased from two in the first full year of collection in 2017 to 13 in 2021. Similarly, the average number of patients presenting for tonsil stone evaluation per month increased steadily from 1.0 in 2017 to 3.3 in 2021. TikTok video content under the search result "tonsil stones" varied and the number of videos on this topic has increased in recent years.

CONCLUSION

Rates of patients seeking tonsillectomy for tonsil stones increased from 2016 to 2021 in conjunction with the rising popularity of TikTok. Given the numerous TikTok videos featuring tonsil stones, we believe that this social media platform may be influencing the number of patients seeking evaluation for tonsil stones. This data may be used to understand future influence patterns of social media posts on healthcare consumer behavior and patient care practices.

Tethered Oral Tissue Release Among Breastfed Infants: Maternal Sources of Information and Treatment

BACKGROUND

Despite limited clinical consensus regarding surgery for tethered oral tissues ("tongue-tie") for resolving breastfeeding-related issues, the procedure has been increasing in the United States. Greater understanding of maternal experiences with obtaining surgical release may help to improve breastfeeding outcomes.

RESEARCH AIM

To explore experiences of breastfeeding mothers with infants having undergone "tongue-tie" surgery.

METHOD

This online, cross-sectional, observational survey occurred between August and September 2020. Eligibility included being ≥ 18 years of age and previously or currently breastfeeding an infant with ≥ 1 tissue surgically released. Of 463 screens, 318 mothers were eligible and 115 consented. The final sample was 90.

RESULTS

The sample was predominantly white (n = 86; 95%), non-Hispanic (n = 84; 93%), married/cohabitating (n = 85; 94%), and currently providing their own milk (n = 81; 89%).Difficult latch was the primary reason for seeking help. Participants reported lingual (n = 84; 93%), labial (n = 79; 88%), and buccal (n = 16; 17%) tissue-release, with 80% (n = 73) reporting > 1 released. For each tissue released, > 80% (n = 72) of participants felt "very confident" in their ability to correctly identify it and 97% (n = 87) felt "very involved" and "strongly agreed" with surgical release. International Board Certified Lactation Consultants^® were the most frequently identified source of information (n = 45; 50%) and referrals (n = 38; 42%), while pediatric dentists most frequently performed interventions (n = 60; 67%).

CONCLUSIONS

Participants reported being confident, involved, and in agreement with surgical release and lactation support professionals were frequent information and referral sources.

Severity and prevalence of ankyloglossia-associated breastfeeding symptoms: A systematic review and meta-analysis

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.

Survey of Pediatric Otolaryngology Frenotomy Practice Patterns

OBJECTIVES

Assess current frenotomy practice patterns of pediatric otolaryngologists via a cross-sectional survey.

STUDY DESIGN

Survey study.

METHODS

A 31-question electronic survey assessing frenotomy practice patterns was distributed to all American Society of Pediatric Otolaryngology (ASPO) members. Descriptive statistics were used to summarize responses and demographics of respondents.

RESULTS

Of all ASPO members, 41% (240/588) completed the survey. Most respondents, 185 (77%), reported increased frenotomy referrals over the last 5 years and 144 (60%) described the current number of referrals as "too many." The two primary lingual frenotomy indications identified in infants were: breastfeeding/nipple pain (92%) and inability to latch (83%). For older children, speech difficulty (87%) was the primary indication. Maxillary frenotomy indications in infants varied amongst respondents. For analgesia during in-office frenotomy procedures, respondents used glucose/sucrose drops (48%), topical lidocaine (29%), or no pain control measure (27%). For post-procedure care, respondents recommended continuing lactation support (45%), massaging/stretching the wound (38%), or none (40%). Most respondents, 143 (60%), reported having seen a complication from frenotomy, and the most reported frenotomy complications were frenulum re-attachment and excessive bleeding.

CONCLUSIONS

In the last 5 years, otolaryngologists have seen an increase in referrals for frenotomy. Pediatric otolaryngologists have varying practice patterns with regards to ankyloglossia diagnosis and treatment. The reported indications for frenotomy varied amongst pediatric otolaryngologists especially with respect to maxillary frenotomy. Practice patterns also varied with respect to procedural pain control and frenotomy aftercare recommendations. More frenotomy research is needed to establish a standard of care for patients with ankyloglossia.

Upper lip tie: A novel classification scale with improved inter-rater reliability

Objectives

Upper lip tie (ULT) is a clinical condition with restrictive attachment of the superior labial frenulum (SLF), which may inhibit flanging of the lips. Objective outcome studies are lacking in part due to unreliable classification systems that rely solely upon a single attachment parameter of the SLF. This study's objectives are to describe a novel 3-point classification system for ULT and compare its inter-rater reliability to the Kotlow and Stanford systems.

Methods

Five raters used the Kotlow and Stanford systems, as well as our novel 3-point scale to score images of the SLF from 20 newborns seen at our institution between September 1, 2017 and April 1, 2018. Newborn birth weight, gestational age, and demographic data were collected from the infant's medical record. Fleiss's kappa was used to calculate inter-rater reliability for all classification systems.

Results

The parameters for our novel 3-point classification system for ULT were as follows: length from alveolar edge to frenulum gingival attachment, length of frenulum on stretch, and free-lip to total-lip length ratio. Our novel scale yielded the highest inter-rater reliability of 0.41, compared to 0.24 and 0.25 under the Kotlow and Stanford systems.

Conclusion

While the Kotlow and Stanford systems are based upon a single anatomical parameter, our novel 3-point classification scale uses three oral parameters that encompass anatomical points of attachment as well as the maximal length of the ULT on stretch. Our classification scheme is the first to incorporate a functional parameter of the SLF, and thereby more fully characterizes ULT.Level of Evidence: Level 4.

Effectiveness of Myofunctional Therapy in Ankyloglossia: A Systematic 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.

Post Frenotomy Massage for Ankyloglossia in Infants-Does It Improve Breastfeeding and Reduce Recurrence?

OBJECTIVES

Frenotomy is performed in breast fed infants who experience difficulty in latching after failed conservative management for ankyloglossia or tongue-tie. Though parents sometimes enquire about massage after frenotomy, neither published evidence nor clinical consensus supports this. The aim of our study was to assess if there was significant difference in breast feeding or recurrence rate between those infants who had post frenotomy massage and those who did not.

METHODS

A retrospective study was conducted in a tertiary Children's hospital from January 2018 to December 2018. The tongue-tie service consisted of five pediatric surgical consultants, three of whom routinely advice post frenotomy massage. As a result, we had two groups to compare -massage and non-massage group. Total sample size (n = 599) consisted of those who were advised massage (n = 282) and those who were not advised massage (n = 317).

RESULTS

Overall recurrence rate was 4/599 (0.66%) and this did not achieve statistical significance between the two groups. Breast feeding rates were also similar in both the groups. However, it is interesting to note that only 43.5% of those advised massage adhered to the massage regimen.

CONCLUSIONS

Improvement in breast feeding and recurrence after frenotomy were similar between massage and non-massage groups. This confirms the lack of any additional benefit of post frenotomy massage. This study assists clinicians with decision making not to advise massage as it is unlikely to benefit infants with tongue-tie.

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.

Systematic review of the evidence for resolution of common breastfeeding problems-Ankyloglossia (Tongue Tie)

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.

Controversy Over Tongue-Tie: Divisions in the Community of Healthcare Professionals

While recent decades have seen a rapid rise in cases of infant tongue-tie and in surgery to correct it, a controversy is now raging over the condition. Opinion is especially divided over so-called posterior tongue-tie, a variant which is detected based on the "feel" of the sub-lingual space. Drawing on ethnographic research with clinicians in England, we clarify the professional and personal commitments involved in the controversy. Our analysis is informed by Douglas' theory of cultural representations (grid-group theory), in which ideas of what is natural and unnatural constitute central metaphors.

Re-thinking lactation-related nipple pain and damage

Nipple pain is a common reason for premature cessation of breastfeeding. Despite the benefits of breastfeeding for both infant and mother, clinical support for problems such as maternal nipple pain remains a research frontier. Maternal pharmaceutical treatments, and infant surgery and bodywork interventions are commonly recommended for lactation-related nipple pain without evidence of benefit. The pain is frequently attributed to mammary dysbiosis, candidiasis, or infant anatomic anomaly (including to diagnoses of posterior or upper lip-tie, high palate, retrognathia, or subtle cranial nerve abnormalities). Although clinical protocols universally state that improved fit and hold is the mainstay of treatment of nipple pain and wounds, the biomechanical parameters of pain-free fit and hold remain an omitted variable bias in almost all clinical breastfeeding research. This article reviews the research literature concerning aetiology, classification, prevention, and management of lactation-related nipple-areolar complex (NAC) pain and damage. Evolutionary and complex systems perspectives are applied to develop a narrative synthesis of the heterogeneous and interdisciplinary evidence elucidating nipple pain in breastfeeding women. Lactation-related nipple pain is most commonly a symptom of inflammation due to repetitive application of excessive mechanical stretching and deformational forces to nipple epidermis, dermis and stroma during milk removal. Keratinocytes lock together when mechanical forces exceed desmosome yield points, but if mechanical loads continue to increase, desmosomes may rupture, resulting in inflammation and epithelial fracture. Mechanical stretching and deformation forces may cause stromal micro-haemorrhage and inflammation. Although the environment of the skin of the nipple-areolar complex is uniquely conducive to wound healing, it is also uniquely exposed to environmental risks. The two key factors that both prevent and treat nipple pain and inflammation are, first, elimination of conflicting vectors of force during suckling or mechanical milk removal, and second, elimination of overhydration of the epithelium which risks moisture-associated skin damage. There is urgent need for evaluation of evidence-based interventions for the elimination of conflicting intra-oral vectors of force during suckling.

The effect of frenotomy on long-term breastfeeding in infants with ankyloglossia

INTRODUCTION

The World Health Organization has issued guidelines suggesting exclusive breastfeeding for at least six months for all infants. However, one of the main factors interfering with successful breastfeeding is ankyloglossia. Frenotomy may help improve breastfeeding, but evidence on the long-term effects on breastfeeding is lacking. Therefore, this study was conducted to evaluate the effect of frenotomy on breastfeeding and identify factors associated with receiving exclusive breastfeeding for six months.

METHODS

This was a cross-sectional descriptive study conducted using retrospective chart review. Infants diagnosed with anterior ankyloglossia who underwent frenotomy at HRH Princess Maha Chakri Sirindhorn Medical Center between April 1, 2013 and March 31, 2019 were included. Data on both the mothers and the infants were collected. The length and types of feeding at 2, 4, 6, and 12 months were recorded.

RESULTS

In total, 526 infants were included in the study; 322 (61.22%) were male. Their median age on the day of surgery was 2 days (minimum 1 day, maximum 30 days). In total, 7.03% did not receive breastfeeding, whereas 17.96% and 75.01% had received breastfeeding for fewer than and more than six months, respectively. The prevalence of infants exclusively breastfed decreased over time from 81.37% to 55.70%, 33.46%, and 4.38% at 2, 4, 6, and 12 months, respectively. The study did not show any independent factors of neonatal and maternal characteristics associated with being exclusively breastfed for six months.

CONCLUSION

Among infants with anterior ankyloglossia who received frenotomy, 33.46% were exclusively breastfed for six months. The study did not show any independent factors of neonatal and maternal characteristics associated with being exclusively breastfed for six months.

Impact and outcome evaluation of HealthPathways: a scoping review of published methodologies

INTRODUCTION The HealthPathways programme is an online health information system used mainly in primary health care to promote a consistent and integrated approach to patient care. AIM The aim of this study is to perform a scoping review of the methodologies used in published impact and outcomes evaluations of HealthPathways programmes. METHODS The review included qualitative, quantitative or mixed-methods evaluations of the impact or outcome of HealthPathways. MEDLINE, Embase, CINAHL and Web of Science databases were searched. Seven programme aims were identified in the impact and outcome evaluation: (1) increased awareness and use of HealthPathways; (2) general practitioners are supported to adopt best practice, patient-centred care; (3) increased appropriate use of resources and services; (4) improved quality of referrals; (5) enhanced consistent care and management of health conditions; (6) improved patient journeys through the local health system; and (7) reduction in health-care cost and increased value for money. RESULTS Twenty-one studies were included in the final review; 15 were research papers and six were reports. 'Increased awareness and use of HealthPathways' was the most frequent programme aim evaluated (n = 12). Quantitative and qualitative research methodologies, as well as prospective and retrospective data collections, have been adopted to evaluate the impact and outcome of HealthPathways. DISCUSSION Assessing the impacts and outcomes of HealthPathways may be challenging due to limitations in primary data and the interconnectedness of change across the measured aims. Each aim may therefore require specific methodologies sensitive enough to capture the impact that HealthPathways are making over time.

Factors associated with frenotomy after a multidisciplinary assessment of infants with breastfeeding difficulties

OBJECTIVE

Frenotomy for ankyloglossia has increased nearly 10-fold over the past few decades despite insufficient evidence that the procedure improves breastfeeding outcomes. There is no universally accepted method for identifying patients who may benefit from the procedure. The objective of this study is to determine if comprehensive feeding evaluations and targeted interventions can identify children who should undergo procedures, and to identify factors associated with lip or tongue frenotomy to treat breastfeeding difficulties.

METHODS

This observational quality improvement study followed infant-mother dyads between March 2018 and December 2019 referred to our tertiary care center for breastfeeding difficulties. Speech and language pathologists performed comprehensive feeding evaluations on infants prior to surgical consultation for frenotomy. Infants' oral anatomy and function and their ability to breast and bottle feed were assessed, and techniques for mothers to address feeding difficulties without a procedure were offered prior to surgical consultation. Infants either found success over a short observation period or underwent procedures (lip and/or tongue frenotomy).

RESULTS

153 patients (mean age 47.0 days (stdev 39.0 days, 56.2% male) were referred for surgical division of the lingual frenulum. Following development of a program utilizing pediatric speech language pathologists to perform feeding evaluations prior to surgical consultation, 69.9% of patients subsequently did not undergo surgical procedures. 11 (23.9%) underwent labial frenotomy alone and 30 (65.2%) underwent both labial and lingual frenotomies. Frenotomy was associated with significantly increased worry subscale of the Feeding Swallow Impact Survey (FSIS) and decreased mean Breastfeeding Self Efficacy Scale score (p = 0.0001, p = 0.006, respectively). Tongue appearance was significantly associated with having a procedure, while lip appearance was not. The Bristol Breastfeeding Assessment Tool (BBAT) was lower in children undergoing tongue and/or lip frenotomy (p = 0.0006), while the Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) appearance and function scores were lower in children undergoing lingual frenotomy with or without lip frenotomy (p = 0.0008, p = 0.0009, respectively).

CONCLUSIONS

The majority of patients referred for ankyloglossia may benefit from nonsurgical intervention strategies based on findings from comprehensive feeding evaluation. Frenotomy is associated with higher maternal feeding-related worry and reduced breastfeeding self-efficacy scores. While tongue appearance is associated with frenotomy, functional assessment is critical for identifying patients who may also benefit from lip frenotomy.

Ankyloglossia: Update on Trends in Diagnosis and Management in the United States, 2012-2016

Ankyloglossia, or "tongue-tie," refers to limited tongue mobility caused by a restrictive lingual frenulum. Previous studies have demonstrated rapid increases in diagnosis and treatment of ankyloglossia in the United States up to 2012. We performed an updated retrospective review of data from the National Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality (AHRQ) to evaluate trends in diagnosis of ankyloglossia and use of lingual frenotomy in the hospital setting. From 2012 to 2016, there was an 110.4% increase in reported diagnosis of ankyloglossia in the inpatient setting with similar increases in lingual frenotomy procedures. As seen previously, sex, type of insurance, median income ZIP code, and geographic region were associated with diagnosis of ankyloglossia. The observed trends from prior to 2012 have continued to increase, while unanswered questions about diagnostic criteria and about which infants should undergo frenotomy remain.

Clinical Consensus Statement: Ankyloglossia in Children

OBJECTIVE

To identify and seek consensus on issues and controversies related to ankyloglossia and upper lip tie in children by using established methodology for American Academy of Otolaryngology-Head and Neck Surgery clinical consensus statements.

METHODS

An expert panel of pediatric otolaryngologists was assembled with nominated representatives of otolaryngology organizations. The target population was children aged 0 to 18 years, including breastfeeding infants. A modified Delphi method was used to distill expert opinion into clinical statements that met a standardized definition of consensus, per established methodology published by the American Academy of Otolaryngology-Head and Neck Surgery.

RESULTS

After 3 iterative Delphi method surveys of 89 total statements, 41 met the predefined criteria for consensus, 17 were near consensus, and 28 did not reach consensus. The clinical statements were grouped into several categories for the purposes of presentation and discussion: ankyloglossia (general), buccal tie, ankyloglossia and sleep apnea, ankyloglossia and breastfeeding, frenotomy indications and informed consent, frenotomy procedure, ankyloglossia in older children, and maxillary labial frenulum.

CONCLUSION

This expert panel reached consensus on several statements that clarify the diagnosis, management, and treatment of ankyloglossia in children 0 to 18 years of age. Lack of consensus on other statements likely reflects knowledge gaps and lack of evidence regarding the diagnosis, management, and treatment of ankyloglossia. Expert panel consensus may provide helpful information for otolaryngologists treating patients with ankyloglossia.

Complications following frenotomy for ankyloglossia: A 24-month prospective New Zealand Paediatric Surveillance Unit study

AIM

To investigate the incidence and characteristics of complications arising from frenotomy for ankyloglossia (tongue-tie) in New Zealand.

METHODS

Prospective surveillance among hospital-based paediatricians of complications arising from frenotomy for ankyloglossia to children <1 year old was conducted by the New Zealand Paediatric Surveillance Unit for 24 months, from August 2016 to July 2018, inclusive.

RESULTS

A total of 16 cases of complications arising from frenotomy were reported. The overall average annual incidence rate was 13.9/100 000. Geographic variation was noted with a peak of 85.6/100 000 in one region. Complications reported: poor feeding (44%), respiratory events (25%), pain (19%), bleeding (19%) and weight loss (19%). Three children (19%) also had delayed diagnosis of an underlying medical condition initially overlooked in favour of treating their ankyloglossia, this has not previously been reported. The majority (75%) of cases required admission to hospital. Treatments given included supplementary feeds (44%), surgical intervention (25%), breastfeeding support (19%), analgesia (13%) and blood products (13%). A total of 25% of children had one or more frenotomies; 50% were treated for two or more of: 'anterior' ankyloglossia, 'posterior' ankyloglossia or 'lip tie'; 50% had their frenotomies performed out of the hospital. Dentists were the most common performing practitioner (31%).

CONCLUSIONS

Frenotomy rates in New Zealand are unknown. Poor feeding, pain, bleeding, weight loss and delayed diagnosis of an alternative underlying medical condition are important complications that require hospital assessment and admission. Practitioners and parents/families need to be aware of these possibilities. Centralised guidelines with access to specialist second opinions should be developed.

Association of Feeding Evaluation With Frenotomy Rates in Infants With Breastfeeding Difficulties

Importance

Inpatient surgical release of lingual frenulums rose 10-fold between 1997 and 2012 despite insufficient evidence that frenotomy for ankyloglossia is associated with improvements in breastfeeding. Clear indications for surgical release remain murky, and best practice guidelines have yet to be developed.

Objective

To determine whether infants referred for frenotomy to treat breastfeeding difficulties should undergo procedures after comprehensive feeding examination, during which the primary cause of feeding issues was identified, and targeted intervention was provided.

Design, Setting, and Participants

This observational quality improvement study followed mother-infant dyads between March and December of 2018 who were referred to our tertiary care center for difficulty with breastfeeding. All infants underwent a comprehensive feeding evaluation by speech and language pathologists who examined the infants' ability to breastfeed prior to a surgical consultation for initial frenotomy. Data analysis was performed between January 2019 and May 2019.

Interventions

A multidisciplinary feeding evaluation that examined infants' oral structure and function and their ability to breastfeed and that offered techniques for mothers to address any feeding difficulties prior to surgical intervention was developed. Infants either found success in feeding and weight gain through this program or underwent procedures.

Main Outcomes and Measures

The primary outcome was the percentage of frenotomy procedures following implementation of a multidisciplinary feeding team evaluation. The secondary outcome was the percentage of infants referred for lingual frenotomy who later had either combined lingual and labial frenotomy or labial frenotomy alone.

Results

Included in the study were 115 patients (median age, 34 days [interquartile range, 19-56 days], 68 (59%) were male) referred for surgical division of the lingual frenum. Following the development of a program with feeding examination with a pediatric speech and language pathologist, 72 (62.6%) patients subsequently did not undergo surgical procedures. Although all of the referrals were for lingual frenotomy, 10 (8.7%) underwent labial frenotomy alone and 32 (27.8%) underwent both labial and lingual frenotomy.

Conclusions and Relevance

The majority of patients referred for ankyloglossia may benefit from alternative intervention strategies following comprehensive feeding evaluation. Close collaboration and formation of multidisciplinary teams are imperative for treating these children.

The development and evaluation of a picture tongue assessment tool for tongue-tie in breastfed babies (TABBY)

Background

The presence of a tongue-tie (ankyloglossia) in an infant may lead to breastfeeding difficulties, but debate continues about which babies should be treated with frenotomy. The Bristol Tongue Assessment Tool (BTAT), a clear and simple evaluation of the severity of tongue-tie, is being used worldwide and translated into different languages. We aimed to produce a simple picture version of the BTAT to aid and enhance consistent assessment of infants with tongue-tie.

Methods

The Tongue-tie and Breastfed Babies (TABBY) assessment tool was developed from the BTAT by a graphic designer, with iterative discussion with four practicing NHS midwives. The TABBY tool consists of 12 images demonstrating appearance of the infant tongue, its attachment to the gum and the limits of tongue mobility. The TABBY tool is scored from 0 to a maximum of 8.Two initial audits of the TABBY were undertaken at a large maternity unit in a secondary care NHS Trust, in Bristol UK from 2017 to 2019. TABBY was evaluated by five midwives on 262 babies with tongue-ties and experiencing breastfeeding difficulties who were referred for assessment to a tongue-tie assessment clinic using both BTAT and TABBY. Each pair of scores was recorded by one midwife at a time. A further training audit with 37 babies involved different assessors using BTAT and TABBY on each baby.

Results

All midwives found the TABBY easy to use, and both audits showed 97.7% agreement between the scores. We suggest that a score of 8 indicates normal tongue function; 6 or 7 is considered as borderline and 5 or below suggests an impairment of tongue function. Selection of infants for frenotomy required an additional breastfeeding assessment, but all infants with a score of 4 or less in the audits had a frenotomy, following parental consent.

Conclusions

The TABBY Assessment Tool is a simple addition to the assessment of tongue-tie in infants and can provide an objective score of tongue-tie severity. Together with a structured breastfeeding assessment it can inform selection of infants for frenotomy. It can be used by clinical staff following a short training and will facilitate translation into other languages.
