This relatively common dental procedure may be done with soft-tissue lasers, such as the CO2 laser.A frenotomy can be performed as a standalone procedure or as part of another surgery. The procedure is typically quick and is performed under local anesthesia. First, the area under the tongue is numbed with an injection. Once the patient is numb, a small incision is made in the tissue and the tongue is freed from its tether. The incision is then closed with dissolvable sutures. Recovery from a frenotomy is typically quick and most patients experience little to no pain or discomfort.According to Lalakea and Messner, surgery can be considered for patients of any age with a tight frenulum, as well as a history of speech, feeding, or mechanical/social difficulties. Adults with ankyloglossia may elect the procedure. Some of those who have done so report post-operative pain.Horton et al., have a classical belief that people with ankyloglossia can compensate in their speech for a limited tongue range of motion. For example, if the tip of the tongue is restricted for making sounds such as /n, t, d, l/, the tongue can compensate through dentalization; this is when the tongue tip moves forward and up. When producing /r/, the elevation of the mandible can compensate for restriction of tongue movement. Also, compensations can be made for /s/ and /z/ by using the dorsum of the tongue for contact against the palate rugae. Thus, Horton et al.
