Frenotomy

Frenotomy is a quick, minor surgical procedure that involves cutting a small band of tissue called a frenulum. It is most commonly performed on infants to release a tight band under the tongue (tongue-tie) or lip (lip-tie). The goal is often to improve breastfeeding difficulties by allowing for better movement of the tongue or lip.

What is Frenotomy?

Frenotomy is a simple surgical procedure to release a frenulum, which is a small fold of tissue that connects two parts of the body. The most common type is a lingual frenotomy, which addresses a tight band under the tongue (lingual frenulum). Another type is a labial frenotomy, which addresses a tight band under the upper lip (labial frenulum).

This procedure is often called a "tongue-tie release" or "lip-tie release." It involves a quick cut to the frenulum to allow for more movement of the tongue or lip. The procedure is typically performed by a trained clinician, such as a pediatrician, oral surgeon, or ENT (ear, nose, and throat) specialist. The frenulum is a normal part of anatomy, but sometimes it can be unusually short or tight. When this happens, it can restrict movement, leading to various issues. Frenotomy aims to correct this restriction by freeing the affected tissue.

Why it's done

Frenotomy is primarily performed to address conditions like ankyloglossia (tongue-tie) or a tight lip frenulum, especially when these conditions cause problems. In infants, the main reason for the procedure is to improve breastfeeding difficulties, such as poor latch, nipple pain for the mother, or slow weight gain for the baby.

Ankyloglossia, or tongue-tie, occurs when the lingual frenulum is unusually short, thick, or tight, tethering the bottom of the tongue to the floor of the mouth. This can limit the tongue's ability to move freely, making it hard for an infant to latch properly onto the breast. Mothers might experience significant nipple pain, and babies may struggle to get enough milk, leading to poor weight gain. While less common, a frenotomy may also be considered for older children or adults if a tight frenulum causes speech problems, difficulty eating certain foods, or issues with oral hygiene. However, the evidence for benefits in these cases is not as strong as for infant breastfeeding difficulties. A clinician will assess whether a frenotomy is appropriate based on the specific symptoms and their impact.

How to prepare

Preparing for a frenotomy is usually straightforward, especially for infants. Your clinician will provide specific instructions, but generally, there isn't much special preparation needed. For infants, it's often helpful to plan to feed the baby immediately after the procedure, as this can help with comfort and encourage proper tongue or lip movement.

Before the procedure, your clinician will examine your baby's mouth to confirm the presence and severity of the tongue-tie or lip-tie. They will discuss the potential benefits and risks with you and answer any questions you may have. It's important to share any concerns or your baby's medical history with the clinician. For older children or adults, preparation might involve discussing any medications you are taking or any allergies you have. In some cases, you might be advised to avoid eating or drinking for a short period before the procedure, especially if sedation is planned. Always follow your clinician's specific guidance.

What happens during

During a frenotomy, the clinician makes a quick, small incision to release the tight frenulum. For infants, the procedure is very fast, often lasting only a few seconds. It can be done in a doctor's office or clinic, sometimes without anesthesia or with a topical numbing gel.

The clinician will gently hold the baby's head to keep it still. Using sterile scissors or a laser, they will carefully snip the frenulum. When scissors are used, the cut is typically quick and precise. If a laser is used, it vaporizes the tissue, which can help to reduce bleeding and may not require stitches. Bleeding is usually minimal, often just a few drops, and can be controlled with gentle pressure. Many infants are able to breastfeed immediately after the procedure, which can be comforting and helps them practice using their newly freed tongue or lip. The entire process is generally well-tolerated by infants.

Recovery & timeline

Recovery from a frenotomy is typically very quick, with most infants able to resume normal feeding immediately after the procedure. Any discomfort is usually mild and short-lived, often managed by breastfeeding or comfort measures. Complete healing of the small incision site usually occurs within a few days to a week.

After the procedure, you might notice a small, diamond-shaped wound under the tongue or lip. This area will heal quickly. Your clinician may recommend gentle stretches or exercises for the tongue or lip to prevent the frenulum from reattaching as it heals. These exercises are simple and help maintain the increased range of motion. Pain relief, if needed, is usually minimal for infants and can often be achieved through feeding. For older children or adults, over-the-counter pain relievers might be suggested. It's important to keep the area clean and follow any specific post-procedure care instructions provided by your clinician to ensure proper healing and prevent complications.

Risks & side effects

Frenotomy is generally considered a safe procedure with a low risk of serious complications. The most common side effect is minor bleeding at the site of the incision, which usually stops quickly. Other risks, though rare, include infection, damage to surrounding structures, or the frenulum reattaching.

Minor bleeding is often just a few drops and can be managed with gentle pressure. While infection is possible with any surgical procedure, it is rare after a frenotomy due to the small size of the wound and good oral hygiene. Your clinician will advise you on signs of infection to watch for, such as increased redness, swelling, or pus. Very rarely, there could be damage to the tongue, salivary glands, or nerves. Another rare complication is reattachment, where the frenulum tissue grows back together, potentially requiring a second procedure. Your clinician will discuss these risks with you before the procedure and explain how they are minimized.

Success rate

Frenotomy has a moderate success rate, particularly for improving breastfeeding difficulties in infants with tongue-tie. Many mothers report a reduction in nipple pain and an improvement in their baby's latch immediately after the procedure. However, the evidence is less clear for long-term outcomes like sustained breastfeeding duration or infant weight gain.

Studies suggest that frenotomy can lead to small to moderate improvements in maternal nipple pain and the infant's ability to latch effectively. While many families experience positive changes, it's important to remember that breastfeeding success depends on many factors, and frenotomy is one tool that may help. For some infants, additional support from a lactation consultant may be beneficial after a frenotomy to help optimize feeding techniques. If the procedure is done for speech issues in older children, the success can vary depending on the individual and the underlying cause of the speech difficulty. Your clinician can provide a realistic expectation of outcomes based on your specific situation.

Frequently asked questions

Is frenotomy painful for a baby?

For infants, frenotomy is a very quick procedure, often causing only brief discomfort. Many babies cry for a short moment but are quickly comforted, especially when allowed to breastfeed immediately afterward. Sometimes, a topical numbing gel is used to minimize any pain.

How long does it take for a frenotomy to heal?

The small incision from a frenotomy typically heals very quickly. For most infants, the wound site will look much better within a few days, and complete healing usually occurs within one to two weeks. Your clinician may recommend gentle exercises to aid healing and prevent reattachment.

Can a frenulum grow back after a frenotomy?

While rare, it is possible for the frenulum to reattach or for scar tissue to form that restricts movement again. This is sometimes called reattachment or re-tethering. Following any post-procedure exercises recommended by your clinician can help reduce this risk.

Will my baby need stitches after a frenotomy?

No, stitches are typically not needed after a frenotomy. The incision is very small, and the tissue heals quickly on its own. If a laser is used, it often seals the tissue as it cuts, further reducing the need for stitches and minimizing bleeding.

What should I do if my baby is still having feeding problems after a frenotomy?

If your baby continues to experience feeding problems after a frenotomy, it's important to follow up with your clinician. They can assess the healing and provide further guidance. Consulting with a lactation consultant can also be very helpful, as they can offer additional support and strategies for breastfeeding.

Is frenotomy always necessary for tongue-tie or lip-tie?

No, frenotomy is not always necessary. The decision to perform a frenotomy depends on whether the tongue-tie or lip-tie is causing significant problems, such as breastfeeding difficulties, speech issues, or other functional limitations. Your clinician will evaluate your specific situation and discuss if the procedure is recommended.
