Orofacial rehabilitation after severe orofacial and neck burn: Experience in a Brazilian burn reference centre

To quantify the benefits of a functional oral rehabilitation program for impairment caused by full thickness orofacial and neck burns, comparing the effects of early and late intervention.

An observational cross-sectional study was conducted in a burn reference center over a two-year period. Patients with full thickness orofacial and neck burns were divided in two groups: Group 1 was composed by 14 patients who began the rehabilitation program 3-12 months after the burn injury; Group 2 was composed by 15 patients who began the rehabilitation program more than 12 months after the burn injury. Treatment was based on current strategies of non-surgical exercises for orofacial contracture management. Outcome measurements included an oral motor clinical evaluation and the assessment of the mandibular range of movement.

The functional rehabilitation program was effective in reestablishing the oral motor functions (i.e deficits reduced to approximately 15% when compared to the optimal possible scores) and in restoring horizontal mouth opening dimensions, with more than 70% of the patients presenting measurements within the expected normal limits at the end of treatment. Our results did not indicate differences in performance between the group of patients in neither set of assessments, i.e. pre and post treatment (p > 0.05).

The results of this study indicate that non-invasive orofacial contracture management is effective for patients with orofacial and neck burns, including those with long term sequelae.
