In early infancy (up to 4 months), the procedure may be performed without anaesthesia with little discomfort to the infant. The infant is placed supine with the elbows held flexed securely close to the face. The tongue is lifted gently with gloved finger and thumb so as to expose the frenulum. With sterile scissors, the frenulum is released by approximately 2 to 3 mm at its thinnest portion, between the tongue and the alveolar ridge, into the sulcus just proximal to the genioglossus muscle. Care is taken not to incise any vascular tissue (the base of the tongue, the genioglossus muscle, or the gingival mucosa). There should be minimal blood loss, i.e., no more than a drop or 2, collected on sterile gauze. (Ballard JL, Auer CE, and Khoury JC)
