Ankyloglossia or tongue-tie refers to an abnormally short lingual frenulum. Ankyloglossia is a recognized but poorly defined condition and has been reported to cause feeding difficulties, dysarthria, dyspnea, and social or mechanical problems in childhood and adolescence. This article reports a simple, safe, and effective way for management of ankyloglossia associated with restricted movement of the tongue. The treatment involved a diode laser for removal of the lingual frenum, which healed uneventfully. A marked improvement in the movement of the tongue was observed at follow-up visits in the treated case.

Ankyloglossia, also known as tongue-tie, is a congenital anomaly characterized by an abnormally short lingual frenulum.[1] Clinically, the term has been used to describe different situations, such as a tongue that is fused to the floor of the mouth as well as a tongue with impaired mobility due to a short and thick lingual frenulum.[2]

There is continuing controversy over the diagnostic criteria and treatment of ankyloglossia.[3] Several studies establish diagnostic criteria based on the length of the lingual frenulum,[4] amplitude of tongue movement,[5],[6],[7],[8] heart-shaped look when the tongue is protruded and thickness of the fibrous membrane.[9],[10],[11]

Based on the length of the free tongue,[12] ankyloglossia can be classified as follows:

Clinically acceptable: Normal >16 mm Class I: Mild ankyloglossia 12–16 mm Class II: Moderate ankyloglossia 8–11 mm Class III: Severe ankyloglossia 3–7 mm Class IV: Complete ankyloglossia: Less than 3 mm.

In children, ankyloglossia can lead to breastfeeding difficulties, speech disorders, poor oral hygiene and bullying during childhood and adolescence. Nowadays, several surgical techniques have been described to correct an abnormal frenulum.[6],[9],[11],[13],[14],[15],[16]

Laser has several advantages over conventional surgical treatment modalities which include bloodless operating field, no postoperative infection or pain and no suturing required. The case report discusses successful management of ankyloglossia or tongue tie with diode laser.

 Case Report

A 12-year-old male patient reported with a chief complaint of not being able to talk clearly and difficulty in protruding his tongue completely. Medical history was Non-contributory. On oral examination, the patient was found to have short lingual frenum with restricted tongue movements. It was observed that when the mouth was open, it was impossible for the patient to protrude his tongue. This clinical condition was diagnosed as Class IV ankyloglossia according to kotlows classification [Figure 1] and [Figure 2].{Figure 1}{Figure 2}


Frenectomy of the lingual frenum was planned using a 980 nm diode laser [Figure 3]. After obtaining informed consent, topical anesthetic was applied to the underside of the tongue and local anesthetic infiltration was administered into the frenum area. After the anesthesia had been found to be effective, tongue was elevated using a clamp to stabilize it. As the frenum became prominent, the diode laser which was activated at 2 W in continuous mode was applied using initiated tip of 300 µm in contact mode from the apex of the frenum to the base in a brushing stroke thereby cutting the frenum. The ablated tissue was mopped continuously using wet gauze piece. This takes care of the charred tissues and prevents excessive thermal damage to the underlying tissue. Protrusive tongue movement was checked to access complete elimination of frenum [Figure 4] and [Figure 5]. No bleeding was observed, and no suturing was done. Patient was prescribed analgesics and postoperative exercises and reviewed after 1-week [Figure 6]. Healing was uneventful. Patient reported increased tongue mobility following surgery and was at ease.{Figure 3}{Figure 4}{Figure 5}{Figure 6}


Diode lasers can be used in continuous wave or gated-pulse modes in contact or out of contact with the tissue. The benefits of using laser in oral surgical procedures are significant for the clinician as well as the patient. Laser light is monochromatic, coherent and collimated therefore it delivers a precise burst of energy to the targeted area. There is more efficient incision of the tissues by laser when compared to the scalpel, laser generates complete vaporization and coagulates the blood vessels. Laser has a hemostatic effect that eliminates excessive bleeding which creates clean surgical field allowing increased precision and accuracy and greatly improving visualization of surgical site. Laser wound causes less bleeding due to sealing of capillaries by protein denaturation and stimulation of clotting factor VII. The thermal effect of laser seals the capillaries and lymphatics which reduces the postoperative bleeding and edema.[17] Because of improved healing and hemostasis laser wounds can often be left without sutures. Laser assisted frenectomy is believed to provide better postoperative perception of pain and function than with the scalpel technique.[18] Laser assisted lingual frenectomy is easy, showing excellent precision and less discomfort compared to the conventional technique. High level of sterilization is maintained in diode treatment which reduces the need for postoperative care and antibiotics.


Ankyloglossia or tongue-tie is a congenital condition for which treatment can be made simple and safe. In the present case report, lingual frenectomy was done by diode laser technique which provided the practical benefit to the patient by reducing bleeding, increasing asepsis, decreasing operative and postoperative pain, swelling and no requirement of suture.
