Background: Craniofacial microsomia (CFM) is a complex, congenital, malformation, primarily involving structures
derived from the first and second branchial arches. There is limited information on its long-term management and outcomes.
Objective: To present the long-term management and outcome of a patient with CFM treated by early distraction osteogenesis
and a protocol of comprehensive care at the Tawanchai Center, Srinagarind Hospital, Khon Kaen University.
Material and Method: After reviewing the medical records for the clinical presentations, assessments, and long-term managements and outcomes of patients with CFM at Srinagarind Hospital, we focused on one patient, treated by early surgical reconstruction, mandibular distraction osteogenesis (DO), and comprehensive care according to the protocol developed at the Tawanchai Center.
Results: The patient presented normal speech, mouth breathing, normal swallowing, and normal temporomandibular joint function. He had an antimongoloid slant, left malar hypoplasia, a cross bite, occlusal plane canting and a slightly deviated chin to the right, a good mouth opening, and a normal bite pattern. The patient was completely satisfied according to overall satisfaction, nose, and upper lip; and moderately satisfied according to overall face, head shape, and occlusion.
Conclusion: Our study suggests that the use of DO in young children with CFM provides good long-term distraction on the
growth of the mandible and greater facial symmetry. The study addresses the comprehensive evaluation of the long-term,
interdisciplinary, comprehensive care of a patient with CMS. Consideration of the needs and expectations of the patient and
his/her family and other involved stakeholders is essential.
