Introduction: ANKYLOGLOSSIA characterized by mild to complete mucosal bands whereby the tongue is tied to the floor of the mouth. This oral anomaly can affect nutrition, speech and oral hygiene, and mechanical/social effects. Materials and Methods: This study was a randomized clinical trial conducted in Tabriz Children's Hospital. All patients were randomly divided into two groups, group A and B, each of which included 20 patients. The electrocautery frenectomy under local anesthesia and simple frenuluplasty under general anesthesia was performed for the patients of A and B groups, respectively. Results: The patients were evaluated on the first day after the operation in terms of inflammatory signs and symptoms, on the seventh day after the operation in terms of wound healing and any complications, and one month after the operation in terms of scarring and wound contraction. Nothing by mouth (NPO) time was only 1 hour for electrocautery frenectomy and no need for general anesthesia. There were no postoperative complications (e. g., erythema and eczema) in group A, and only one infant (i. e., 5% of the population) showed symptoms of fever in this group. In group B, on the other hand, 10% of the population showed signs of erythema, and 26% showed signs of eczema at the incision site after the surgery. Speech status was improved in all cases in the electrocautery group. Conclusion: It seems that the frenectomy with electrocautery has better results in terms of short surgery time and postoperative complications compared to the traditional surgical method.
