Use of High-Power Diode Laser in Neonatal Lingual Frenulum Release Surgery: Clinical Approach and Assessment of Healing in a Case Series.

Ankyloglossia is a congenital condition characterized by restricted tongue mobility due to an abnormal lingual frenum, which may impair breastfeeding in newborns and infants. Early diagnosis and treatment are essential to prevent functional complications. This case series describes 35 newborns and infants with ankyloglossia who underwent frenectomy using a super-pulsed dual-wavelength diode laser. The procedures were performed using a diode laser operating at wavelengths of 810 nm (1.2 W) and 980 nm (1.4 W), delivering a final output power of 1.1 W, in super-pulsed mode (20 Hz frequency, 0.05 ms pulse width), with a 400-μm fiber optic tip. Healing and tongue mobility were evaluated immediately after surgery and at seven and 15 days. Most cases showed balanced tissue repair, absence of fibrosis, and improved tongue mobility, resulting in effective breastfeeding. Unfavorable outcomes were associated with external factors such as pathological healing history and poor adherence to postoperative care.
