control group. The study concluded that ankyloglossia can adversely affect breastfeeding in certain infants. Infants with ankyologlossia do not, however, have such big difficulties when feeding from a bottle. . Limitations of this study include the small sample size and the fact that the quality of the mother’s breast feeding was not assessed.

Wallace and Clark also studied breastfeeding difficulties in infants with ankyloglossia. . They followed 10 infants with ankyloglossia who underwent surgical tongue tie division. Eight of the ten mothers experienced poor infant latching onto the breast, 6/10 experienced sore nipples and 5/10 experienced continual feeding cycles; 3/10 mothers were exclusively breastfeeding. Following a tongue tie division, 4/10 mothers noted immediate improvements in breastfeedings, 3/10 mothers did not notice any improvements and 6/10 mothers continued breastfeeding for at least four months after the surgery. The study concluded that tongue tie division may be a possible benefit for infants experiencing breastfeeding difficulties due to ankyloglossia and further investigation is warranted. The limitations of this study include that the sample size was small and that there was not a control group. In addition, the conclusions were based on subjective parent report as opposed to objective measures.

Speech

Messner and Lalakea studied speech in children with ankyloglossia. They noted that the phones likely to be affected due to ankyloglossia include sibilants and lingual sounds such as [t d z s θ ð n l]. In addition, the authors also state that it is uncertain as to which patients will have a speech disorder that can be linked to ankyloglossia and that there is no way to predict at a young age which patients will need treatment. The authors studied 30 children from one to 12 years of age with ankyloglossia, all of whom underwent frenuloplasty. Fifteen children underwent speech evaluation before and after surgery. Eleven patients were found to have abnormal articulation before surgery and nine of these patients were found to have improved

articulation after surgery. Based on the findings, the authors concluded that it is possible for children with ankyloglossia to have normal speech in spite of decreased tongue mobility. However, according to their study, a large percent of children with ankyloglossia will have articulation deficits that can be linked to tongue tie and these deficits may be improved with surgery. The authors also note that ankyloglossia does not cause a delay in speech or language but, at the most, problems with enunciation. Limitations of the study include a small sample size as well as a lack of blinding of the speech-language pathologists who evaluated the subjects’ speech.

Messner and Lalakea also examined speech and ankyloglossia in another study. They studied 15 patients and speech was grossly normal in all of the subjects. However, half of the subjects reported that they thought that their speech was more effortful than other peoples’ speech.

Horton et al. discussed the relationship between ankyloglossia and speech. The authors believe that tongue tie contributes to difficulty in range and rate of articulation and that compensation is needed. Compensation at its worst, the article states, may involve a Cupid's bow of the tongue.

While the tongue tie exists, and even years after removal, common speech abnormalities include mispronunciation of words. The most common is pronouncing Ls as Ws; for example the word "lemonade" would come out as "wemonade."

Mechanical/Social

Ankyloglossia can result in mechanical and social effects. Lalakea and Messner studied 15 people, aged 14 to 68 years. The subjects were given questionnaires in order to assess functional complaints associated with ankyloglossia. Eight subjects noted one or more mechanical limitations which included cuts or discomfort underneath the tongue and difficulties with kissing, licking one’s lips, eating an ice cream cone, keeping one’s tongue clean and performing tongue tricks.
