COMPARATIVE ANALYSIS OF ANESTHETIC TECHNIQUES IN LINGUAL FRENOTOMIES THROUGH INFANT CRYING: A RANDOMIZED CLINICAL TRIAL IN CHILDREN
Abstract - Ankyloglossia is considered a congenital anomaly characterized by the short insertion of the lingual brake. Babies with this anomaly may present restrict tongue mobility, providing swallowing difficulties, deficiency in breastfeeding, and even early weaning. This study was to compare anesthetic techniques for frenotomy through the analysis of infant crying. This randomized clinical trial (UTNU111112483748) consisted of 24 children aged 2 to 3 months, indicated for frenotomy from May to October 2019, performed by the pediatric dentistry team of the Health Unit Service (HUS), in Gurupi, Tocantins State, Brazil. Three anesthetics commonly used for this surgical intervention were tested. The children were evaluated by sound recording at two moments of the surgical act by a mobile device with a calibrated "decibel meter" application. The mean intensities of infant crying in surgery with phenylephrine/tetracaine topical were significantly lower than the mean intensities when lidocaine injection (p = 0.0096) was used, but the same statistical procedure applied, comparing topical Benzocaine versus lidocaine injection, showed no significant difference (p = 0.35). The methods of noninvasive topical applications were better than invasive ones, the sound analysis showed that topical application of ophthalmic eye drops of tetracaine/phenylephrine proved to be the best analgesia in frenotomies.
