INTRODUCTION: Treacher Collins Syndrome (TCS) is a congenital craniofacial malformation, characterized by zygomatic and mandibular hypoplasia, that may lead to impaired masticatory function.
OBJECTIVE: To characterize the masticatory function of children and adults with TCS in comparison to a control group (CON).
MATERIALS AND METHODS: Fifty-four participants were divided into two age- and sex-matched groups: 1) CON: 27 non-syndromic participants (13 children and 14 adults); and 2) TCS: 27 participants with TCS (13 children and 14 adults). Masticatory function was assessed using two tests: 1) Bite Force (BF): using a gnathodynamometer; and 2) Granulometry (GM): size of food particles after 20 masticatory cycles of standardized samples.
RESULTS: The mean BF in children with TCS (108.87 ± 48.64 N) was significantly lower than that observed in the CON group (343.97 ± 156.06 N). Similarly, among adults, the BF in the TCS group (233.28 ± 136.83 N) was significantly lower than that of the CON group (412.07 ± 227.62 N). Within the TCS group, children exhibited significantly lower BF than adults, a pattern not observed in the CON group. Children with TCS presented significantly larger particle sizes (0.83 ± 0.86 mm2) than controls (0.26 ± 0.13 mm2). Among adults, no significant differences were observed between groups. Comparisons between age groups showed that children with TCS produced significantly larger particles than adults with TCS.
CONCLUSION: Masticatory function is impaired in participants with TCS, particularly in the pediatric population. The findings underscore the importance of ongoing multidisciplinary clinical and therapeutic care for this population.
