Introduction: Ankyloglossia is commonly known as tongue tie. It is a congenital anomaly that causes feeding and speech problems. Treatment options include frenotomy, frenectomy and frenuloplasty. In this case report, we present the treatment of a male patient with ankyloglossia with frenectomy. Case Presentation: A 6-year-old male, without any systemic disease, presented to our clinic with the complaint of restricted speech and tongue movements and was diagnosed with ankyloglossia. The patient was planned to undergo lingual frenectomy under local anesthesia. Bilateral lingula nerve block anesthesia was applied for surgical treatment. The lower part of the tongue adhering to the floor of the mouth and the frenulum adhering to the tip of the tongue were held with a hemostat. After incision was made with the help of a scalpel, blunt dissection was performed during surgery. After it was determined that the tongue was completely freed, the wound ends formed under the tongue and on the floor of the mouth were sutured with 4.0 vicryl sutures. After the operation, it was observed that the patient could easily stick out her tongue. No postoperative complications were encountered. Conclusion: Ankyloglossia is a clinical picture that causes speech difficulties by restricting tongue movements and may also cause gingival inflammation and mandibular diastema. Lingual frenectomy in the mixed dentition period will prevent these problems and their psychological complications. Keywords: Ankyloglossia, Tongue tie, Frenectomy
