OBJECTIVE
To see the relationship of the lingual frenum with speech and other oral functions, evaluating the surgical indications and the results of frenectomy.
MATERIAL AND METHODS
In 1997 we operated 72 children with sublingual frenulum, a telephone questionnaire to the mothers of these patients was done, obtaining data about: age at surgery, professional reasons for referral, preoperative findings, pre-post operative speech therapy, place of surgery and type of anesthesia and mother's impression about the final result.
RESULTS
Fifty valid questionnaires were obtained, the mean age at frenectomy was 3.03 years, 38% of children were sent due to speech problems, 60% due to some degree of tongue-tie and 2% due to dentofacial developmental anomalies. In 70% the patients were sent by a pediatrician and in 14% by a speech therapist. In 20% preoperative speech therapy was done and postoperatively in 30%. In 48% of cases, aged less than 2 years, speech was not possible to be evaluated. In the 11 cases with questionable results, a multidisciplinary reevaluation showed 7 cases with lingual dysfunction and poor tongue control, 4 cases with deglutitory anomalies and 3 cases with orofacial occlusal problems secondary to lingual dysfunction or altered oral habits.
CONCLUSIONS
The presence of a nondisturbing lingual frenulum does not justify its surgical section, the frenectomy is indicated only in presence of altered oro-lingual functions caused by the tongue-tie such as: speech problems, errors of bite and deglutition, lingual dysfunction and anomalous oral habits.
