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.

Tongue-tie: incidence and outcomes in breastfeeding after lingual frenotomy in 2333 newborns

AIM

To determine the prevalence of ankyloglossia in newborns with breastfeeding problems and to assess the effectiveness of frenotomy in the maintenance of exclusive breastfeeding at 1 month, 3 months and 6 months in newborns at an Andorran Hospital.

STUDY DESIGN

A descriptive, cross-sectional, population-based, retrospective study of newborns over a 5-year period (2016-2020) was performed. Nine medical history variables (presence or absence of ankyloglossia and type of frenulum, surgical intervention or not, first degree hereditary component, gender, Rh and blood group, type of breastfeeding, causes of cessation and duration of breastfeeding) related to perinatal and feeding history were collected confidentially and anonymously. The Coryllos classification was used for the diagnosis of ankyloglossia. Descriptive analysis of the data, Chi-square test and prevalence ratios were calculated.

RESULTS

A total of 2333 newborns were included in the study (50.02% males and 49.98% females). The prevalence of ankyloglossia was 7.84% (n = 183). Of the infants examined, 136 underwent lingual frenotomy. The number of infants who maintained exclusive breastfeeding, both surgically and non-surgically treated, was no statistically significant differences at 1 month (p = 0.65), 3 months (p = 0.61) and 6 months (p = 0.49).

CONCLUSIONS

Lingual frenotomy was only performed on patients with ankyloglossia associated with ineffective suction that causes BF difficulties. The realization or not of frenotomy was not a determining factor for the maintenance of breastfeeding at 1 month, 3 months and 6 months. On the contrary, it was a determining factor for the prolongation of mixed feeding. Ankyloglossia related to breastfeeding difficulties should be treated by a multidisciplinary team.

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.

Association between superior labial frenum and maxillary midline diastema - a systematic review

BACKGROUND

Pediatric otolaryngologists have seen an increased focus on upper lip frenum as a possible culprit for feeding difficulties and the development of maxillary midline diastema (MMD). This increase may be encouraged by parents' exposure to medical advice over the internet about breastfeeding and potential long-term aesthetic concerns for their children. Subsequently, there has been increased pressure on pediatric otolaryngologists to perform superior labial frenectomies. There has been a reported 10-fold increase in frenectomies since the year 2000. However, there is no consensus within the literature regarding the benefit of superior labial frenectomy in preventing midline diastema.

OBJECTIVE

To provide physicians and parents with the most updated information by systematically reviewing the available literature for the association between superior labial frenum and midline diastema.

METHODS

A literature search was performed in MEDLINE (PubMed), EMBASE, Web of Science, the Cochrane Library and Dental and Oral Sciences Source (DOSS). Using the Covidence platform, a systematic review was conducted. The initial 314 articles identified underwent systematic review and 11 studies were included in the final review.

RESULTS/DISCUSSION

Available data, primarily from the dental literature, showed that two subtypes of frenum: papillary and papillary penetrating frenum, are associated with maxillary midline diastema. Superior labial frenectomy should be delayed until permanent lateral incisors have erupted, as this can spontaneously close the physiological MMD. Current literature recommends against frenectomy before addressing the diastema with orthodontics, which helps to prevent diastema relapse. It is also imperative to rule out other odontogenic and oral cavity causes of diastema, such as thumb sucking, dental agenesis, and other causes. Online information may not always be fully representative and should be interpreted in the full context of the patient's medical history before referral for surgical intervention.

Comparison of the analgesic effect of inhaled lavender vs vanilla essential oil for neonatal frenotomy: a randomized clinical trial (NCT04867824)

It is necessary to treat neonatal pain because it may have short- and long-term adverse effects. Frenotomy is a painful procedure where sucking, a common strategy to relieve pain, cannot be used because the technique is performed on the tongue. In a previous randomized clinical trial, we demonstrated that inhaled lavender essential oil (LEO) reduced the signs of pain during neonatal frenotomy. We aimed to find out whether inhaled vanilla essential oil (VEO) is more effective in reducing pain during frenotomy than LEO. Randomized clinical trial with neonates who underwent a frenotomy for type 3 tongue-ties between May and October 2021. Pain was assessed using pre and post-procedure heart rate (HR) and oxygen saturation (SatO2), crying time, and NIPS score. Neonates were randomized into "experimental" and "control" group. In both groups, we performed swaddling, administered oral sucrose, and let the newborn suck for 2 min. We placed a gauze pad with one drop of LEO (control group) or of VEO (experimental group) under the neonate's nose for 2 min prior to and during the frenotomy. We enrolled 142 neonates (71 per group). Both groups showed similar NIPS scores (2.02 vs 2.38) and crying times (15.3 vs 18.7 s). We observed no differences in HR increase or in SatO2 decrease between both groups. We observed no side effects in either of the groups.

CONCLUSIONS

We observed no appreciable difference between LEO and VEO; therefore, we cannot conclude which of them was more effective in treating pain in neonates who underwent a frenotomy.

TRIAL REGISTRATION

CLINICALTRIALS

gov with NCT04867824.

WHAT IS KNOWN

• Pain management is one of the most important goals of neonatal care as it can have long-term neurodevelopmental effects. • Lavender essential oil can help relieve pain due to its sedative, antispasmodic, and anticolic properties.

WHAT IS NEW

• Lavender and vanilla essential oils are safe, beneficial, easy to use, and cheap in relieving pain in neonates who undergo a frenotomy for type 3 tongue-ties.

Analgesic effect of inhaled lavender essential oil for frenotomy in healthy neonates: a randomized clinical trial

BACKGROUND

Neonatal pain may affect long-term neurodevelopment and must be treated. Frenotomy is a painful procedure wherein a common strategy to relieve pain (sucking) cannot be used because the technique is performed on the tongue. Lavender essential oil (LEO) has sedative and antispasmodic properties and has been successfully used to treat pain during heel puncture and vaccination. Our aim was to demonstrate if the use of inhaled LEO is effective in reducing pain during frenotomy in healthy, full-term neonates.

METHODS

We conducted a randomized clinical trial in neonates who underwent a frenotomy between August 2020 and April 2021. We assessed pain using pre and post-procedure heart rate and oxygen saturation, crying time and Neonatal Infant Pain Scale (NIPS) score. Patients with type 3 tongue tie were randomized into the "experimental group" and "control group". In both groups, we performed swaddling, administered oral sucrose, and let the newborn suck for two minutes. In the experimental group, we also placed a gauze pad with one drop of LEO under the neonate's nose for two minutes prior to and during the frenotomy.

RESULTS

We enrolled 142 patients (71 per group). The experimental group showed significantly lower NIPS scores (1.88 vs 2.92) and cried almost half the amount of time (14.8 vs. 24.6 seconds, P = 0.006). Comparing with the control group, we observed no side effects in either of the groups.

CONCLUSIONS

We observed a significant decrease in crying time and lower NIPS scores in the neonates who received inhaled LEO and underwent a frenotomy for type 3 tongue-ties. Thus, we recommend using inhaled LEO during neonatal frenotomies.

Pediatric Office Procedures

Pediatric patients are frequently evaluated in primary care clinics. Thus, there exists a need to understand common pediatric problems and to acquire a degree of familiarity with pediatric procedures. This article will review techniques and the current evidence for frequently performed pediatric procedures, including umbilical granuloma chemocautery, frenotomy, suture ligation of type B postaxial polydactyly, reduction of nursemaid's elbow, hair tourniquet removal, and tympanometry.

Prevalence of ankyloglossia in newborns and impact of frenotomy in a Baby-Friendly Hospital

Background

Ankyloglossia is a condition present in some newborns and can be associated with breastfeeding difficulties, leading to symptoms in the child and the mother. This study aimed to analyze the characteristics of newborns with tongue-tie and the symptoms reported by their mothers, and the short and long-term outcomes of frenotomy.

Methods

We conducted a prospective and observational 7-month study in a Baby-Friendly Hospital (BFH). We included all the breastfed newborns without comorbidities that underwent a frenotomy.

Results

A total of 33 frenotomies were performed. The most common findings before the procedure were maternal breastfeeding pain (29/33), ineffective latch (18/33), and maternal nipple lesions (18/33). We observed that newborns surgically intervened later showed a high incidence of jaundice (p = 0.03), weight loss greater than 10% at hospital discharge (p = 0.004), and their mothers experienced pain more often (p = 0.004). At one month of age, there was an improvement in breastfeeding-related pain (p = 0.012) and its intensity (p = 0.016), the presence of maternal cracked nipples (p < 0.01), and latching on (p < 0.01).

Conclusions

Ankyloglossia can prevent the correct establishment of breastfeeding. Frenotomy is associated with few complications, and when appropriately indicated, may have a positive impact on breastfeeding, reducing maternal pain, the presence of nipple lesions, and latching problems.

Parental and provider perspectives on social media about ankyloglossia

OBJECTIVES

To investigate and identify the concerns and opinions expressed in both parental and provider posts on social media about ankyloglossia.

METHODS

In this study, posts on Twitter between 1/1/2008 and 12/31/2018 were collected using search terms and hashtags specific to pediatric ankyloglossia. The search terms included a primary phrase to indicate ankyloglossia along with a pediatric identifier. Tweets that met inclusion criteria were analyzed qualitatively via conventional content analysis. After all tweets were categorized, descriptive statistics were completed to determine frequency of each theme.

RESULTS

In total, 5951 tweets were retrieved. Parents authored 982 (16.5%) of tweets, and 782 (13.1%) were by providers. The remaining 4187 tweets did not fit criteria for either the parent or provider groups. Amongst parents, the most common themes mentioned were feeding problems (309 tweets [32.4%]), followed by lip tie (215 [22.5%]), anxiety or emotion (207 [21.7%]), and maternal breastfeeding complications (127 [13.3%]). The number of tweets about ankyloglossia and frenotomy in 2018 had increased by 2395% since 2009. Amongst providers, 215 tweets were judged by the coders to provide an opinion on ankyloglossia, of which 94.4% had a pro-frenotomy sentiment. When a specialty was identified, tweets were most often by dentists (250 [31.9%]), followed by lactation consultants and International Board Certified Lactation Consultants (IBCLCs) (157 [29.7%]) and non-otolaryngologist physicians (79 [10.1%]). Otolaryngologists accounted for 8.7% (68 tweets) of posts about ankyloglossia.

CONCLUSION

Our findings demonstrate the spectrum of opinions that exist among both parents and providers about ankyloglossia. This can aid in shared-decision making by enabling the counseling provider to guide recommendations based on medical evidence with the understanding that there is a large amount of non-scientific information and opinions disseminated that may be shaping decisions.

Tongue function characteristics in infants experiencing breastfeeding difficulties and changes in breastfeeding after frenotomy procedures

OBJECTIVES

The aims of the study were to describe tongue function in infants experiencing breastfeeding difficulties and to examine changes in breastfeeding after frenotomy procedures.

MATERIALS AND METHODS

Mothers, and their infants, facing difficulties in breastfeeding were referred to the Vilnius University hospital Žalgirio clinic after assessment of breastfeeding quality by a lactation specialist. Anatomy evaluations included the type of ankyloglossia, tongue function, and the need for a frenotomy. All mothers completed the breastfeeding questionnaire twice, once during the referral consultation and 1 month later. The total breastfeeding hindrance score was calculated before and after the frenotomy.

RESULTS

Fifty infants were included in the study and their mean age was 29.6 days (min age 1 day and max 78 days). The male to female ratio was 1.8:1.0. Of all infants, 70% had severe lingual function alterations and their mothers were facing issues in breastfeeding. After the frenotomy, there was a significant reduction in breastfeeding hindrance in infants who had disturbed function and aberrant anatomic characteristics. It was found that for type II ankyloglossia, the frenotomy procedure was significant more (p = 0.002) beneficial, than for type I ankyloglossia. After the frenotomy, there was a significant improvement in nine out of 14 criteria of breastfeeding (p = 0.001).

CONCLUSIONS

Frenotomy procedures had a positive effect on improving breastfeeding.

CLINICAL RELEVANCE

Current study analyses issues with breastfeeding. Dental practitioners and pediatricians should be familiar with this topic, as early and timely minimal invasive surgical intervention has a significant impact for better comfort of the mothers and continuation of breastfeeding.

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.

Major complications after tongue-tie release: A case report and systematic review

INTRODUCTION

The diagnosis of ankyloglossia, or tongue-tie, and the number of frenotomies performed has increased over 10-fold from 1997 to 2012 in the United States. The sharpest increase has been in neonates. For parents considering frenotomy for their breastfeeding newborn, there is controversy surrounding the evaluation of tongue-tie and the benefit of a frenotomy. Complications from tongue-tie procedures are thought to be low, though it is not well reported nor studied.

OBJECTIVES

The aim of this study is to describe a case of a sublingual mucocele after laser frenotomy in a neonate with tongue-tie and to investigate major complications reported after tongue-tie release in pediatric patients through a systematic review of the literature.

CASE REPORT

We present a 6-week-old female who underwent a laser frenotomy procedure performed by a dentist who presented with a new cyst under her tongue.

MATERIAL AND METHODS

A systematic literature search of articles published from 1965 to April 2020 was conducted in Ovid MEDLINE(R), Ovid EMBASE, and Scopus. Citations were uploaded into a systematic review software program (DistillerSR, Ottawa, ON, Canada), followed by full text screening.

RESULTS

47 major complications were reported in 34 patients, including our patient. Most of the cases were located in the United States and Europe. The most frequent indications for the procedure were breastfeeding problems (n = 18) and speech impediment (n = 4). The procedure was performed by dentists (n = 6), lactation consultants (n = 5), and otolaryngologists (n = 4). The bulk of the major complications after frenotomy included poor feeding (n = 7), hypovolemic shock (n = 4), apnea (n = 4), acute airway obstruction (n = 4), and Ludwig angina (n = 2).

CONCLUSIONS

Reporting of complications after frenotomy is lacking. Risks to neonates may be different than risks to older children and adults. Practitioners across different specialties should be monitoring and studying this more rigorously to better guide patients and families on the risks and benefits of this procedure.

Trends in outpatient intervention for pediatric ankyloglossia

OBJECTIVES

Anecdotally, there has been an increase in ankyloglossia referrals and frenotomy procedures performed in recent years. Many studies have characterized frenotomy indications and outcomes, but none have quantified how the frequency of referrals and interventions have changed over time in the outpatient setting. This study analyzes temporal trends in the diagnosis and intervention of ankyloglossia in a pediatric otolaryngology practice to further clarify how patterns of management of this condition have changed over time.

METHODS

This study was a retrospective chart review of patients evaluated for ankyloglossia in an outpatient pediatric otolaryngology clinic between 2008 and 2018. The chi-square test for trend was used to assess yearly changes in the referral numbers, surgical interventions, and procedure indication prevalence proportions of interest.

RESULTS

Referral numbers and frenotomy procedures increased as a percentage of total office visits from 2008 to 2018 (P = 0.0026, P < 0.0001). The trend in frenotomies was especially pronounced in the 0 to 2-month age group (P < 0.0001) but was not observed in the 2 months to 1-year (P = 0.30) or 1- to 4-year (P = 0.40) age groups. Frenotomy performed for concerns of feeding (P < 0.0001) increased over the study period, but there was no significant increase in procedures performed for speech concerns (P = 0.13).

CONCLUSION

Significant increases in referrals for frenotomy and number of frenotomy procedures performed are demonstrated, especially in young infants for feeding concerns. It is unlikely representative of a true increase in the incidence of ankyloglossia, but rather the result of cultural and clinical factors driving referrals and intervention.

Comparison of simple frenotomy with 4-flap Z-frenuloplasty in treatment for ankyloglossia with articulation difficulty: A prospective randomized study

OBJECTIVE

To compare the surgical outcomes of simple frenotomy and the 4-flap Z-frenuloplasty according to the articulation test values and tongue-tie classification in patients with ankyloglossia with articulation difficulty.

STUDY DESIGN

prospective randomized study.

SETTING

Tertiary academic center.

SUBJECTS

and methods: Children with ankyloglossia with articulation difficulty were randomly divided into 2 groups for surgical treatment. Patients were evaluated for the tongue-tie classification and articulation test before surgery. Three months after the operation, the frenulum classification and articulation test were re-evaluated to compare the differences in surgical outcome between the two surgical methods.

RESULTS

Out of 37 patients, 19 underwent the 4-flap Z-frenuloplasty and 18, the simple frenotomy. No differences were observed in the baseline characteristics of the patients assigned to both groups. Changes in the tongue-tie classification and improvement in the articulation test results were observed with both the surgical methods. Both surgical groups had significant improvement in the speech articulation test (consonants) but there was no difference in the speech outcomes between the surgical groups.

CONCLUSION

Although there was no significant difference in the surgical outcome between the two surgical methods, ankyloglossia patients showed improvement in a Korean speech articulation test 3 months after undergoing surgery to release the lingual frenulum.

Modest benefit of frenotomy for infants with ankyloglossia and breastfeeding difficulties

INTRODUCTION

With nationwide effort to increase breastfeeding rates in newborns and infants in recent years, there has been a dramatic increase in the diagnosis of ankyloglossia, and the resultant otolaryngology referral for frenotomy. Overall, there is a paucity of data on the expected benefit of frenotomy in this population and the subsequent breastfeeding rate. The objectives of this study were to assess the effect of office-based frenotomy on improving breastfeeding difficulties among infants with ankyloglossia from a patient-centered perspective and examine associated effects of frenotomy and ankyloglossia type on breastfeeding.

METHODS

Maternal-infant dyads were referred to a tertiary care otolaryngology practice for assessment of ankyloglossia. A prospective cohort study was conducted in this population from January 2017 to September 2018. Mothers completed questionnaires regarding the quality of breastfeeding before the frenotomy procedure in the office and were subsequently contacted by phone to complete the same questionnaires 1 week and 3 months after the initial encounter. Treating physicians reported ankyloglossia type and expected improvement at the time of the procedure. Descriptive statistics and paired analyses were used to analyze post-frenotomy breastfeeding outcomes and ascertain likelihood of improvement.

RESULTS

During the study period, the mothers of 343 infants agreed to participate in the study by completing the initial questionnaire. Of these infants, 314 (91.5%) underwent frenotomy. Most infants were classified as having either type I (35.3%) or type II (45.2%) ankyloglossia with 16.9% having posterior ankyloglossia and 2.6% with no ankyloglossia. At 1-week post-frenotomy the largest group of patients (35%) had mild improvement in breastfeeding abilities compared to baseline with 14% and 7% reporting moderate or marked improvement respectively. At 3 months after the initial consultation, significantly more patients reported moderate (27%) or marked (17%) improvement when compared to baseline although the exclusively breastfeeding rate at 3 months was low at 20.3% for this cohort.

CONCLUSIONS

This prospective study demonstrated that frenotomy had a modestly positive effect on breastfeeding ability from the mother's perspective in infants referred for ankyloglossia. It is important to educate patients on the multi-factorial nature of breastfeeding and to set realistic expectations prior to recommending the procedure.

Characteristics and considerations for children with ankyloglossia undergoing frenulectomy for dysphagia and aspiration

OBJECTIVE

The purpose of this study is to analyze the basic demographics of patients who underwent frenulectomy at our institution as well as additional considerations regarding age, location of procedure, and possible effects on aspiration.

METHODS

A retrospective chart review was performed based on CPT codes for frenulectomy and basic demographic data was collected. Other information such as presenting symptoms, type of ankyloglossia, location of the procedure, and modified barium swallow study (MBSS) information were also obtained.

RESULTS

A total of 226 (66.4% male) patients underwent frenulectomy in the study time frame. Younger patients underwent frenulectomy for feeding symptoms (average age 6.5 months) and older children typically presented with speech related symptoms (average age 3.8 years). Of patients who had MBSS before and after the procedure, 5/11 (43%) had improvement of their aspiration after frenulectomy.

CONCLUSIONS

Symptomatic ankyloglossia is more common in boys. Two age groups typically present for frenulectomy, infants for feeding difficulties and toddlers/preschoolers for speech related difficulties. Children with aspiration may benefit from frenulectomy, though aspiration is unlikely to resolve if other comorbidities are present. Proper evaluation and documentation of anatomy and functional tongue movement is important for future studies and decision-making regarding frenulectomy.

Ankyloglossia: Last three-years of outpatient care at a tertiary referral center

INTRODUCTION

Ankyloglossia is an oral anomaly characterized by a shortened, thickened lingual frenulum that may cause reduced tongue mobility. However, the diagnosis and management of this condition has long been a debated topic. Given the paucity of high level evidence, management can be frustrating for both families and clinicians. Our study aims to examine differences in the management of ankyloglossia and investigate influencing factors at a single tertiary pediatric referral center.

METHODS

A retrospective chart review was completed of children less than one year of age seen in the outpatient otolaryngology clinic. Billing records were searched for ICD-9 code 750.0 (ankyloglossia) between January 2, 2015 and October 9, 2017 and data extracted from the charts of those meeting inclusion criteria.

RESULTS

A total of 266 charts were reviewed that met the inclusion criteria during the study period. 100 (38%) were female with a mean age of 2.9 months. In the final multivariate regression model, children seen by providers in Group 1 (providers with high rates of frenotomies) had 4.4 times the odds of having a frenotomy as those seen by a provider in Group 2 (providers with low rates of frenotomies) (p < 0.001, 95%CI: 2.2, 8.9), and male children had 2.5 times the odds of having a frenotomy as female children (p = 0.002, 95%CI: 1.4, 4.5).

CONCLUSION

In this study we identify additional variables that may influence the decision to perform a frenotomy in children with ankyloglossia. The significant impact of clinician biases in the management of ankyloglossia suggests arbitrary differences in the way these patients are managed, highlighting the lack of consensus amongst otolaryngologists and the need for clear indications and diagnostic criteria.

Frenotomy for tongue-tie (frenulum linguae breve) showed improved symptoms in the short- and long-term follow-up

AIM

To evaluate clinical manifestations of tongue-tie as well as short-term and long-term outcomes following frenotomy.

METHODS

In this retrospective study, for 329 patients (295 infants and 34 children) who underwent frenotomy between 2011 and 2017, symptoms, short-term and long-term outcomes were evaluated.

RESULTS

Of the 295 infants (median age six weeks), 199 (=60%) showed inadequate breastfeeding. Symptoms were painful or sore maternal nipples, poor weight gain, dribbling milk from the corner of the mouth, reduced milk supply, inadequate latch during bottle-feeding and maternal mastitis. In the 34 children, predominant symptoms were articulation disorders, misaligned teeth and problems with swallowing solid food. Of the 141 patients with short-term feedback, 86% reported improvement, 13% an unchanged situation. In a former premature, the reported worsening of symptoms ('breath spells') are likely related to prematurity. Of the 164 patients where the questionnaire for long-term outcome was provided, 82% reported improvement, 16% an unchanged situation. For two infants worsening was reported, referring to refusal to drink from breast or bottle for two hours after the procedure and fever for one day, respectively.

CONCLUSION

Frenulum breve is a potential cause of breastfeeding difficulties and can be treated safely and efficiently by frenotomy.

Upper lip frenotomy for neonatal breastfeeding problems

OBJECTIVES

Upper lip tie, without concomitant tongue tie, can prevent proper flanging of the upper lip during breastfeeding, resulting in a poor seal and suck for the infant with nipple pain and maternal dissatisfaction. Due to the lack of published studies on this subject, we report our technique and outcomes for in-office release of isolated upper lip tie.

METHODS

Using CPT Code 40,806 for 'incision of labial frenulum', 22 mother-infant dyads with infant age under 60 days with breastfeeding problems and a restrictive upper lip frenum were identified. These infants underwent in-office release of upper lip tie as detailed below. Outcomes of the procedure were assessed by a telephone survey to mothers within the 4-week period post-procedure.

RESULTS

82% of mothers reported an improved latch and 73% noted increased satisfaction with breastfeeding. Lip pain, if present, resolved within 24 h for most children. Recurrence was reported by 9% of mothers; no infection or other complications occurred.

CONCLUSION

Upper lip frenotomy, in properly selected infants, has favorable short-term outcomes with mild transient discomfort and a low rate of recurrence. Since our study was short-term and did not include a control group, we are unable to comment on procedure efficacy or long-term impact.

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.

Breastfeeding problems should be the only relevant criteria for deciding whether to carry out a frenotomy in infancy

Performing a frenotomy on tongue-tied infants is controversial, particularly with regard to breastfeeding issues. This paper reviews the literature to bring together clinical experiences and scientific evidence in this field. I found that some tongue-tied babies may exhibit breastfeeding problems, while others may feed perfectly. The literature suggests that medical breastfeeding-related problems should be the only relevant criteria to guide the decision-making for a frenotomy in infancy. The advantages and disadvantages of either a wait and see position or surgical approach are addressed.

CONCLUSION

The cornerstones for best practice are the meticulous examination, correct diagnosis and classification of tongue-tied infants.

A Randomized Trial to Evaluate the Effect of Two Topical Anesthetics on Pain Response During Frenotomy in Young Infants

Objective

To examine the comparative effectiveness of two topical anesthetics in controlling the pain associated with tongue-tie release (frenotomy) in young infants.

Design

Randomized trial.

Setting

A Pediatric Craniofacial Clinic.

Subjects

Forty-two infants who were referred for frenotomy were randomly allocated to receive the topical anesthetic gel 2% tetracaine or 20% benzocaine applied prior to frenotomy. Frenotomies were videotaped. The primary outcome measure was the Neonatal Facial Coding System (NFCS) score. Secondary outcome measures included cry duration and a visual analog scale (VAS) assessed by the parents.

Results

The two groups were comparable with regard to weight, age, gender, previous painful experience, and last feeding time. Median NFCS scores prior to frenotomy in the tetracaine and the benzocaine groups were 4.5 (IQR: 0.75–10.2) and 3.5 (IQR: 0–9.5), respectively (P = 0.89, 95% CI −3 to 4). During frenotomy, median NFCS score increased to 28 (IQR: 24.5–30.25) in the tetracaine group (P < 0.0001, median difference −22, 95% CI −24.5 to −19), and to 28 (IQR: 26–30) in the benzocaine group (P < 0.0001, median difference −23, 95% CI −27 to −17). Mean cry durations in the tetracaine and the benzocaine groups were 69.4 seconds and 63.9 seconds, respectively (P = 0.32, 95% CI −47 to 15), and mean VAS scores were 57.2 and 58.2, respectively (P = 0.89, 95% CI −15.2 to 13.4).

Conclusions

These topical anesthetics seem ineffective in controlling the pain associated with frenotomy. Clinicians should continue to search for an effective treatment for this procedure.

Long-term efficacy of a tongue tie service in improving breast feeding rates: A prospective study

BACKGROUND

Breast feeding rates in England at 3months of age are approximately 17% for exclusive breast-feeding and 55% for breast-feeds supplemented with formula. Tongue-tie (TT) in infants is cited as a significant cause of difficulty with maintaining breast-feeding. Early treatment and support can improve breast-feeding and allow infants to benefit from the many long-term benefits of breast-feeding. Our aim was to determine BF rates in infants 3months after attending our tongue-tie clinic (TTC).

METHODS

Institutional ethical approval and study approval were obtained. Patients attending the TTC from May to July 2016 were included. Telephone contact was made 3months postprocedure to establish current behaviour. Symptom resolution was recorded as complete resolution (CR), moderate resolution (MoR), or minimal resolution (MiR). Feeding pattern was either exclusively BF or combined breast and formula feeds or exclusively formula fed.

RESULTS

100 infants were included with complete follow-up data on 87 (87% response rate). Median age at release of TT was 17 (2-88) days without any recurrence. Status at 3months was CR (n=70, 80%); MoR (n=13, 15%), and MiR (n=4, 5%). 43 (49%) were exclusively BF, 36 (41%) were supplementing BF with some formula (2/3 by choice and 1/3 owing to insufficient milk production), and 8 (10%) were using only formula milk (7 by choice and 2 owing to ongoing feeding difficulties). Of the 17 mothers still experiencing symptoms, 5 were exclusively breast-feeding, and 8 were persisting with combined feeds.

CONCLUSION

Infants attending our tongue-tie clinic achieved both higher exclusive breastfeeding and combined breast and bottle-feeding when compared to national breast-feeding data at 3months of age. This can facilitate the achievement of long-term breastfeeding, exposing infants and mothers to many of the associated benefits.

Effect of frenotomy on breastfeeding variables in infants with ankyloglossia (tongue-tie): a prospective before and after cohort study

BACKGROUND

Controversy exists regarding ankyloglossia (tongue-tie) and its clinical impact on breastfeeding, including the benefits, or otherwise, of tongue-tie release (frenotomy). As exclusive breastfeeding rates in Ireland are already considerably low (46% on discharge home from the maternity unit following birth in 2014), it is imperative to protect and support breastfeeding, including identifying the associated effects that frenotomy might have on breastfeeding variables.

OBJECTIVE

To determine the associated effects of frenotomy on breastfeeding variables in infants with ankyloglossia.

METHODS

A prospective before and after cohort study was conducted. Following ethical approval, two self-reported questionnaires were administered to women whose infants were undergoing frenotomy at seven healthcare clinics in the Republic of Ireland. Data on breastfeeding variables prior to the frenotomy procedure and at 1-month post-frenotomy were collected and compared. Descriptive statistics (frequencies and proportions) were used to analyse, separately, the pre- and post-frenotomy data. Inferential statistics (z-test scores for differences between proportions (alpha <0.05) and mean differences (MD) with 95% confidence intervals (CI)) were used for pre- and post-frenotomy comparative analyses.

RESULTS

Ninety-eight women returned the baseline questionnaire, and, of these, 89 returned the follow-up questionnaire. The most common reason for seeking a frenotomy was difficulty with latch (38%). Private lactation consultants were the main person recommending a frenotomy (31%). Rates of exclusive breastfeeding remained similar pre- and post-frenotomy (58% versus 58%), although rates of formula feeding increased two-fold at follow-up. Infants' ability to extend their tongues to the lower lip after frenotomy was significantly increased (p < 0.0001). Almost all participants (91%) reported an overall improvement in breastfeeding post-frenotomy. Pain on breastfeeding was significantly reduced post-frenotomy (MD 2.90, 95% CI 3.75 to 2.05) and overall LATCH scale scores were significantly increased (MD -0.50, 95% CI -0.67 to -0.33).

CONCLUSIONS

This study supports the hypothesis that frenotomy has a positive effect on breastfeeding variables in infants with ankyloglossia. These findings, however, are based on a relatively small number of participants from one country only where breastfeeding rates are low. Further, larger studies are required to substantiate these findings.

Changes in the incidence and surgical treatment of ankyloglossia in Canada

BACKGROUND

Recent reports show increases in rates of ankyloglossia and frenotomy in British Columbia. We carried out a study to determine temporal trends and regional variations in ankyloglossia and frenotomy in Canada.

METHODS

The study included all hospital-based live births in Canada (excluding Quebec) between April 2002 and March 2015, with information obtained from the Canadian Institute for Health Information. Information on ankyloglossia and frenotomy was obtained from records of hospital admission for childbirth. Temporal trends and provincial/territorial variations were quantified using rate ratios (RR) and 95% confidence intervals (CI).

RESULTS

Ankyloglossia rates increased from 6.86 in 2002 to 22.6 per 1000 live births in 2014 (P for trend < 0.001), while frenotomy rates increased from 3.76 in 2002 to 14.7 per 1000 live births in 2014 (P for trend < 0.001). Frenotomy rates among infants with ankyloglossia increased from 54.7% in 2002 to 63.9% in 2014 (RR: 1.18, 95% CI: 1.13-1.24). Compared with British Columbia, rates of ankyloglossia were over three-fold higher in Saskatchewan (RR: 3.40, 95% CI: 3.16-3.67), Alberta (RR: 3.50, 95% CI: 3.29-3.72) and the Yukon (RR: 3.62, 95% CI: 2.67-4.92), while rates of frenotomy were three- to four-fold higher in the Yukon (RR: 3.41, 95% CI: 2.28-5.10), Alberta (RR: 4.01, 95% CI: 3.71-4.33) and Saskatchewan (RR: 4.12, 95% CI: 3.76-4.52).

CONCLUSION

A desire to increase rates of breast feeding initiation and absence of standardized criteria for the diagnosis of ankyloglossia have resulted in runaway rates of frenotomy for newborn infants in some parts of Canada.

Management of posterior ankyloglossia and upper lip ties in a tertiary otolaryngology outpatient clinic

OBJECTIVES

Recent studies have shown an association between ankyloglossia (tongue tie) and upper-lip ties to breastfeeding difficulties. Treatment is commonly multidisciplinary involving lactation consultants and surgical management with tongue tie and upper lip tie release. There is currently limited data looking at posterior ankyloglossia and upper lip ties.

METHODS

Consecutive patients seen at an ENT outpatient clinic for ankyloglossia and upper-lip ties from May 2014-August 2015 were assessed for an outpatient frenotomy. Breastfeeding outcomes were assessed following the procedure.

RESULTS

43 babies were seen and 34 patients had a procedure carried out. Babies ranged from 2 to 20 weeks old with the median age being 6.6 weeks. The most common presenting complaint was latching issues (85%) with mothers' painful nipples being the second (65%). 21 patients (62%) had a tongue tie release, 10 (29%) had both a tongue tie and upper lip tie divided, whereas 3 (9%) had an upper-lip tie alone divided. 29 (85%) of the patients who had a procedure carried out had an immediate improvement in breastfeeding, while 28 (82%) had a continued improvement at 2 weeks follow up.

CONCLUSIONS

Frenotomy for posterior ankyloglossia and upper lip ties is a simple procedure that can be carried out in an outpatient setting with apparent immediate benefit. Otolaryngologists are likely to have an increasing role to play in the evaluation and management of ankyloglossia and upper lip ties in babies with breastfeeding difficulties.

Breastfeeding difficulties and oral cavity anomalies: The influence of posterior ankyloglossia and upper-lip ties

OBJECTIVE

Oral cavity anomalies may contribute to breastfeeding problems. The objective of this study was to describe our experience in a high-volume breastfeeding difficulty clinic with a focus on posterior ankyloglossia and upper-lip ties.

METHODS

A retrospective review of patients from a dedicated breastfeeding difficulty clinic from January 2014 to December 2014 was performed. Those identified to have ankyloglossia and/or upper-lip ties underwent release procedures. Subjective breastfeeding changes were documented afterwards.

RESULTS

Of the 618 total patients, 290 (47%) had anterior ankyloglossia, 120 (19%) had posterior ankyloglossia, and 14 (2%) had upper-lip tie. Some patients had both anterior ankyloglossia and upper lip-tie (6%), or posterior ankyloglossia and upper-lip tie (5%). For those with anterior ankyloglossia, 78% reported some degree of improvement in breastfeeding after frenotomy. For those with posterior ankyloglossia, 91% reported some degree of improvement in breastfeeding after frenotomy. Upper lip-tie release also led to improved breastfeeding (100%).

CONCLUSIONS

Anterior and posterior ankyloglossia and upper-lip tie, or combinations thereof, were commonly recognized in our study population. Many newborns, however, also had no oral cavity anomalies. Although causation cannot be implied, these oral cavity anomalies may contribute to breastfeeding difficulties in some cases.

[Diagnosis and management of ankyloglossia in young children]

Ankyloglossia is a common condition. Its prevalence is between 3.2% and 4.8% depending on the series and is largely underestimated given the fact of non-diagnosis when the symptoms are limited. It is defined as a short lingual frenulum resulting in a limitation of the lingual mobility. It is due to a defect in cellular apoptosis embryogenesis between the floor of the mouth and tongue. The result is a fibrous and short lingual frenulum. Several classifications were used to make the diagnosis. However, these are the clinical implications, particularly on food and primarily breastfeeding in the baby and phonation in older children that will motivate the management. This is surgical and different techniques are available: infants before the age of 6 months and when the lingual frenulum is still a fine cellular membrane, frenotomy is recommended. Frenectomy with or without frenoplasty is indicated for the older child. The surgery is simple, the results are good and rapidly improving grievances. Complications are rare. Finally, speech therapy is important when there are implications for phonation.

Ankyloglossia and breastfeeding

Ankyloglossia ('tongue-tie') is a relatively common congenital anomaly characterized by an abnormally short lingual frenulum, which may restrict tongue tip mobility. There is considerable controversy regarding its diagnosis, clinical significance and management, and there is wide variation in practice in this regard. Most infants with ankyloglossia are asymptomatic and do not exhibit feeding problems. Based on available evidence, frenotomy cannot be recommended for all infants with ankyloglossia. There may be an association between ankyloglossia and significant breastfeeding difficulties in some infants. This subset of infants may benefit from frenotomy (the surgical division of the lingual frenulum). When an association between significant tongue-tie and major breastfeeding problems is clearly identified and surgical intervention is deemed to be necessary, frenotomy should be performed by a clinician experienced with the procedure and using appropriate analgesia. More definitive recommendations regarding the management of tongue-tie in infants await clear diagnostic criteria and appropriately designed trials.

Tongue-tie and frenotomy in infants with breastfeeding difficulties: achieving a balance

AIMS

Currently there is debate on how best to manage young infants with tongue-tie who have breastfeeding problems. One of the challenges is the subjectivity of the outcome variables used to assess efficacy of tongue-tie division. This structured review documents how the argument has evolved. It proposes how best to assess, inform and manage mothers and their babies who present with tongue-tie related breastfeeding problems.

METHODS

Databases were searched for relevant papers including Pubmed, Medline, and the Cochrane Library. Professionals in the field were personally contacted regarding the provision of additional data. Inclusion criteria were: infants less than 3 months old with tongue-tie and/or feeding problems. The exclusion criteria were infants with oral anomalies and neuromuscular disorders.

RESULTS

There is wide variation in prevalence rates reported in different series, from 0.02 to 10.7%. The most comprehensive clinical assessment is the Hazelbaker Assessment Tool for lingual frenulum function. The most recently published systematic review of the effect of tongue-tie release on breastfeeding concludes that there were a limited number of studies with quality evidence. There have been 316 infants enrolled in frenotomy RCTs across five studies. No major complications from surgical division were reported. The complications of frenotomy may be minimised with a check list before embarking on the procedure.

CONCLUSIONS

Good assessment and selection are important because 50% of breastfeeding babies with ankyloglossia will not encounter any problems. We recommend 2 to 3 weeks as reasonable timing for intervention. Frenotomy appears to improve breastfeeding in infants with tongue-tie, but the placebo effect is difficult to quantify. Complications are rare, but it is important that it is carried out by a trained professional.

Tongue tie: the evidence for frenotomy

Tongue tie or ankyloglossia is a congenital variation characterised by a short lingual frenulum which may result in restriction of tongue movement and thus impact on function. Tongue tie division (frenotomy) in affected infants with breastfeeding problems yields objective improvements in milk production and breastfeeding characteristics, including objective scoring measures, weight gain and reductions in maternal pain. For the majority of mothers, frenotomy appears to enhance maintenance of breastfeeding. Tongue tie division is a safe procedure with minimal complications. The commonest complication is minor bleeding. Recurrence leading to redivision occurs with rates of 0.003-13% reported; this appears to be more common with posterior than anterior ties. There are limited reports indicating that prophylactic frenotomy may promote subsequent speech development; however, evidence is currently insufficient to condone this practice and further good quality research into this area is warranted.

The development of a new breast feeding assessment tool and the relationship with breast feeding self-efficacy

OBJECTIVE

to develop a breast feeding assessment tool to facilitate improved targeting of optimum positioning and attachment advice and to describe the changes seen following the release of a tongue-tie.

DESIGN

development and validation of the Bristol Breastfeeding Assessment Tool (BBAT) and correlation with breast feeding self-efficacy.

SETTING

maternity hospital in South West England.

PARTICIPANTS

218 breast feeds (160 mother-infant dyads); seven midwife assessors.

FINDINGS

the tool has more explanation than other tools to remind those supporting breast-feeding women about the components of an efficient breast feed. There was good internal reliability for the final 4-item BBAT (Cronbach's alpha=0.668) and the midwives who used it showed a high correlation in the consistency of its use (ICC=0.782). Midwives were able to score a breast feed consistently using the BBAT and felt that it helped them with advice to mothers about improving positioning and attachment to make breast feeding less painful, particularly with a tongue-tied infant. The tool showed strong correlation with breast feeding self-efficacy, indicating that more efficient breast feeding technique is associated with increased confidence in breast feeding an infant.

CONCLUSIONS

the BBAT is a concise breast feeding assessment tool facilitating accurate, rapid breast feeding appraisal, and targeting breast feeding advice to mothers acquiring early breast feeding skills or for those experiencing problems with an older infant. Accurate assessment is essential to ensure enhanced breast feeding efficiency and increased maternal self-confidence.

IMPLICATIONS FOR PRACTICE

the BBAT could be used both clinically and in research to target advice to improve breast feeding efficacy. Further research is needed to establish its wider usefulness.
