Anestésico oftálmico em frenotomia lingual: Uma avaliação randomizada:

This study aimed to verify the effect of anesthetic with ophthalmic eye drops tetracaine hydrochloride 1% and phenylephrine hydrochloride 0.1% in frenotomy in ankyloglossia in infants. The sample consisted of 24 children aged 2 to 6 months, indicated for frenotomy from February to August 2019, performed by the pediatric dentistry team of the Health Unit Service (SUS), in the city of Gurupi, Tocantins State, Brazil. We chose to compare the ophthalmic anesthetic with two anesthetics commonly used in frenotomies. 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.
