Lingual frenotomy for breastfeeding difficulties: indications, surgical techniques and multidisciplinary care in...

Over the last decade, the diagnosis of infant ankyloglossia and the number of lingual frenotomy procedures have increased markedly, particularly in the context of breastfeeding difficulties. Frenotomy is often perceived as a relatively simple solution to poor latch, nipple pain or suboptimal milk transfer, yet expert statements highlight substantial gaps in the evidence base, heterogeneous diagnostic criteria and concerns about overdiagnosis and unnecessary surgery in breastfeeding dyads. This creates important challenges for clinicians and lactation consultants who must distinguish infants with true tongue-tie-related breastfeeding dysfunction from those whose feeding problems are better explained by other factors.

To summarize current evidence on indications for lingual frenotomy in infants and young children with breastfeeding difficulties, to compare commonly used surgical techniques and peri-procedural analgesia strategies, and to outline a multidisciplinary, breastfeeding-centered model of care with a practical decision-making algorithm for clinicians working with breastfeeding dyads.

We performed a narrative review of clinical trials, observational studies, systematic reviews, umbrella reviews and expert consensus statements published in the last ten years. Sources were identified through database searches and reference screening, focusing on infant ankyloglossia, breastfeeding outcomes, frenotomy techniques, procedure-related complications and models of multidisciplinary care. Particular attention was paid to studies reporting breastfeeding-specific outcomes such as nipple pain, latch scores, milk transfer and breastfeeding continuation.

In symptomatic breastfeeding dyads with clearly documented tongue-tie-related breastfeeding dysfunction despite optimal lactation support, lingual frenotomy is associated with reductions in maternal nipple pain, improvements in latch and perceived feeding effectiveness, and modest short-term increases in breastfeeding continuation rates. Simple office-based scissors frenotomy remains the best-studied and most pragmatic technique, with high parental satisfaction and a very low rate of serious complications, whereas laser and electrosurgical methods have not demonstrated superior breastfeeding outcomes and may be associated with higher rates of postoperative oral aversion. Evidence for frenotomy performed primarily for speech issues, reflux-like symptoms or non-specific distress remains weak and heterogeneous, and routine use of the procedure for such indications is not supported. Complications and misdiagnoses are more likely when frenotomy is performed outside structured multidisciplinary care pathways and without comprehensive pre-procedural assessment by clinicians experienced in breastfeeding medicine.

Lingual frenotomy can provide meaningful short-term benefits for carefully selected breastfeeding dyads when substantial, well-documented breastfeeding difficulties persist despite high-quality lactation support and can be clearly linked to restricted tongue mobility. However, frenotomy is not a universal solution to breastfeeding or speech problems, and breastfeeding-centered assessment, optimization of conservative management and shared decision-making with families are essential. A multidisciplinary model involving family physicians, pediatricians, otolaryngologists, lactation consultants and speech and language therapists, supported by standardized assessment tools and a step-by-step algorithm, may help reduce misdiagnoses, unnecessary procedures and preventable complications in infants and young children with suspected ankyloglossia.
