Atmospheric Plasma Lingual Frenectomy Followed by Post Operative Tongue Exercises: A Case Series

The lingual frenulum is a submucosal component significantly involved in the mobility of the tongue. In the case of short lingual frenulum, different surgical approaches have been proposed. Atmospheric plasma is a thermal technique of vaporization or sublimation of the superficial tissues, without going deep, and the resulting fine carbonized layer avoids bleeding. The aim of the present investigation was to evaluate the effectiveness of atmospheric plasma (voltaic arc dermabrasion) for the frenectomy of a short lingual frenulum. A total of 30 patients with an age range between 6-11 years old and a class III/IV Kotlow's ankyloglossia classification were included in the study. The Kotlow's free-tongue, maximal interincisal mouth opening (MIO, mm) and interincisal mouth opening with tongue tip to maxillary incisive papillae at roof of mouth (MOTTIP, mm) were calculated at the baseline, immediately postoperatively (T0), at one week (T1), one month (T2) and two months (T3). A significant increase of Kotlow's measurements, MOTTIP and MIO were detected when comparing the baseline and the T0 (p < 0.05). No significant difference was detected between the T0, T1 and T2 (p > 0.05). The atmospheric plasma demonstrated a very minimal invasive approach for frenectomy, without important or fibrotic complications and with very low recurrence rates.
