Aim The aim of this study was to review the craniofacial growth impairment and different malfunctions associated with short lingual frenum and to assess the validity of lingual frenum surgery based on minimally invasive laser release with a myofunctional approach. Materials and methods Thirty patients, children and adolescents whose ages ranged from 8 years to 18 years, diagnosed with a short lingual frenum and concomitant orthodontic problems and/or presence of associated muscular or postural problems, were treated in this study. Pre-operative tongue assessment was performed following morphological and functional criteria, consisting of measurement of the free tongue, and of visual assessment of tongue protrusion out of the mouth and elevation to the incisive palatal papilla. Postural evaluation was assessed in frontal and lateral view. Laser surgery was completed with local anaesthesia, using Erbium YAG laser (2940 nm, LightWalker, ATFotona, Ljubljana, Slovenia) equipped with sapphire conical tip (600 micron), with energy ranging from 120 to 160 mJ, at 15 Hz frequency, and varying the adjustable pulse duration from 300 μs to 600 μs. Results Significant improvement was noted in 29 of 30 patients comparing preoperative scores to both three-week and twomonth post-op scores. Postural improvement was found in 18 of 30 patients, indicating the multifactorial involvement of different causes for correct body posture. Conclusion This study confirmed the validity of Erbium:YAG laser surgery as an effective technique in children and adolescents to release a short lingual frenum. The functional approach of the procedure performed with the Erbium:YAG laser, and the concomitant myofunctional therapy demonstrated to be simple and safe in children, and adolescents. Because of the multifactorial causes involved in correct body posture, an adequate osteopathic therapy is important to successfully complete the full body rehabilitation.
