Orofacial dysfunctions in infants and young children with acute leukemia

ABSTRACT

Purpose

To Identify the occurrence of orofacial dysfunctions in young children and adolescents with acute leukemia who are undergoing remission chemotherapy.

Methods

Over a period of 16 months, 40 three to eighteen year -old patients with acute leukemia were admitted to the Amazonas State Hemocenter. Of these, 23 were included in the cross-sectional study and submitted to the evaluation of orofacial functions using the Nordic Orofacial Test-Screening, between D30 and D33 of the remission induction phase. The presence of oral manifestations was also evaluated via clinical examination.

Results

Orofacial dysfunction was observed in approximately half of the evaluated cases (n=11). Of these patients, all had alterations in the Dryness of the Mouth (VI) domain and 81.8% (n=9) showed alterations in the Chewing and Swallowing (IV) domain. Mucosites on lips, tongue, floor of the mouth and the oropharynx were the most commonly found oral lesions after the remission induction phase. According to the NOT-S, there was an association between the occurrence of oral lesions in the evaluated patients and the presence of orofacial dysfunction (95% CI, p-value = 0.027).

Conclusion

It is suggested that orofacial dysfunction is frequent in the remission induction phase in children and adolescents with acute leukemia. Studies regarding these orofacial dysfunctions in this population, as well as their relationship with oral lesions, are needed in order to fully understand their functional impact.
