Modest benefit of frenotomy for infants with ankyloglossia and breastfeeding difficulties

Speech Outcomes of Frenectomy for Tongue-Tie Release: A Systematic Review and Meta-Analysis

OBJECTIVE

Tongue-tie, which is also known as ankyloglossia, is a common condition where the lingual frenulum is unusually tight or short. While most literature investigates the impact of tongue-tie on breastfeeding, recent articles have examined its role in speech production in children. However, these have not previously been reviewed systematically. This study aims to determine the impact of tongue-tie on speech outcomes and assess whether frenectomy can improve speech function.

METHODS

In this systematic review, we conducted a comprehensive search of PubMed/MEDLINE, Cochrane Library, Embase, and speechBITE to analyze primary studies investigating the impact of frenectomy for tongue-tie on speech outcomes. We extracted data regarding patient age, male to female ratio, procedure type, follow-up time, and speech outcomes and ran statistical analyses to determine if frenectomy for tongue-tie leads to improvement in speech issues in pediatric patients. Speech outcomes extracted were subjectively measured based on the interpretation of a speech and language pathologist or parent.

RESULTS

Our analysis included 10 studies with an average patient age of 4.10 years, and average cohort size of 22.17 patients. Overall, frenectomy for tongue-tie was associated with an improvement in speech articulation (0.78; 95% CI: 0.64-0.87; P < .01). Increasing patient age was found to be negatively correlated with post-frenectomy speech outcomes (P = .01). However, this relationship disappeared in the adjusted model.

CONCLUSION

Overall, we conclude that frenectomy is a suitable treatment to correct speech issues in select patients with tongue-tie if caught early in childhood. Despite the limited investigations around speech outcomes post-frenectomy, these results are informative to providers treating tongue-tie.

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.

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

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

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

Background

In the past 10–15 years, there has been increased concern about ankyloglossia and its effect on infant breastfeeding. This has been associated with increased performance of frenotomy. Physicians and other healthcare professionals with expertise in breastfeeding have voiced concerns about complications related to the performance of infant frenotomy. Reviews of this topic have reported no significant complications after frenotomy. Other data on complications consist of case reports.

Methods

An online survey was developed by physicians with expertise in breastfeeding and e-mailed to physician and dentist members of Academy of Breastfeeding Medicine (ABM) between 11 November and 31 December 2019. It requested information from the respondents who cared for the mother/infant breastfeeding couple about their experiences personally caring for infants with complications or misdiagnoses related to referral for frenotomy or the performance of a frenotomy. Data were analyzed using chi square, Cramer’s V correlation, and binomial logistic regression.

Results

Of 211 eligible respondents, 129 (61%) had cared for an infant with a complication or misdiagnosis. Two hundred and nine (209) infants were reported to have a complication and 237 had a misdiagnosis. The most common misdiagnoses reported were 101 of 237 infants (43%) with neuromuscular dysfunction and 65 of 237 (27%) with inadequate breastfeeding support. The most common complications reported were a repeat procedure considered/requested/performed 65 of 203 (32%) and oral aversion 57 of 203 (28%). Parental report of infant pain was associated with performance of a posterior frenotomy (Chi Square p < .003). Bleeding was associated with using scissors/scalpel vs laser/bovie/electrosurgery (Chi Square p = .001). Oral aversion was associated with performance of frenotomy by laser/bovie/electrosurgery vs scissors/scalpel (adjusted Odds Ratio of 4.05; 95% CI 2.07, 7.93).

Conclusions

Complications and misdiagnoses are occurring after infant frenotomy. Physicians and dentists should work closely with lactation professionals to provide skilled breastfeeding support and to evaluate for other confounding problems that might impact infant breastfeeding before referral for frenotomy. Randomized controlled trials of optimized lactation support vs. frenotomy and of scissors vs laser in performance of frenotomy are needed.

A Retrospective Cohort Study of the Impact of Upper Lip Tie Release on Breastfeeding in Infants

Objectives: Lingual frenotomies for the purpose of improving infant breastfeeding remain controversial, whereas maxillary frenotomies are even more so given the scant data and differing opinions on the matter. This study aimed at further elucidating the effect that maxillary frenula have on breastfeeding difficulties in infants. Methods: A retrospective chart review was performed on infants approximately aged 0-3 months who presented to a tongue tie/breastfeeding clinic from January to December of 2019. All analyzed infants had both lip and tongue ties classified by a clinician. Data on pre-frenotomy pain scores, lingual Coryllos classification, maxillary Kotlow classification, post-frenotomy complications, and breastfeeding success were captured. Results: Of the 316 infants, 224 underwent their first procedure at the tongue tie/breastfeeding clinic. Two hundred eleven out of 224 infants received a lingual frenotomy only, whereas the remaining 13 (5.8%) underwent both lingual and maxillary frenotomy procedures. Of the group of 211, 207 (98.1%) had successful feeding after 1 procedure; the remaining 4 underwent revision procedures to achieve successful feeding. All maxillary frenulum releases (n = 13) led to successful feeding without the need for revision procedures. Coryllos and Kotlow classification scores were significantly higher in the infants receiving both a maxillary and lingual frenulum release as compared with those receiving solely a lingual frenulum release. Conclusions: The majority (98.1%) of infants receiving a lingual frenulum release alone had successful feeding after only one procedure, and only 5.8% of all infants receiving any intervention required a maxillary frenulum release for successful feeding, calling into question the relative necessity of performing maxillary frenulum releases for breastfeeding difficulties.

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.

Lingual Frenuloplasty for Ankyloglossia in Children: A Case Series

Tongue is an important oral structure that affects speech, position of teeth, periodontal tissue, nutrition, swallowing, nursing, and certain social activities. Tongue-tie or ankyloglossia is a developmental anomaly of the tongue, characterized by an abnormally short, thick lingual frenulum resulting in limited tongue movement. Diagnosis must include functional assessment of tongue mobility, in addition to the physical appearance of the frenulum. Tongue mobility and appearance associated with the insertion, as well as the attachment and the shortness of the lingual frenulum should be evaluated. Ankyloglossia management should be considered at any age considering the risk-benefit evaluation and because of the highest vascularization and mobility of the tongue. Lingual frenuloplasty for the management of ankyloglossia in children is being discussed in the form of case series.

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.
