Hemifacial microsomia (HMF) is a morphological alteration characterized by facial deformities. These alterations are a consequence of a congenital anomalous development of the first and second branchial arches. It may present a genetic or environmental origin or a mixture of both and is considered mostly multifactorial. The clinical presentation varies; however, some characteristics are predominant such as unilateral mandible hypoplasia, agenesis or malformation of the auricular pavilion, and agenesis or malformation of the eye globe. The aim of this paper was to report a clinical case of a patient with late diagnosis of HMF which presented multiple deformities and received treatment with polymethyl methacrylate (PMMA) implant in different concentrations. Aiming for facial harmony, the PMMA implant occurred in the following regions: canine fossa, nasolabial sulcus, mandible, Bichat Ball, chin outline, lip contour, nose base, columella, nose tip, and dorsum. The treatment resulted in significant improvement in the facial symmetry.
Level of Evidence: 5
Background: Polymethyl methacrylate (PMMA) is a dermatologic filler commonly used in esthetic procedures. However, it can also be used in more severe cases such as reconstruction of facial traumas.
Aims:The aim of this report was to describe the use of PMMA in a nasal reconstruction of a patient victim of an automobilist accident which presented previous rejection of autograft.
Patient:A young female patient, 26 y, victim of automobilist accident, with no bone support due to trauma both in the mandibulum and maxilla, presented fracture of several facial bones. Presented rejection of a bone autograft from the skullcap implanted on the nose. In order to harmonize the facial aspect, a nasal fill with PMMA for the anatomic reconstruction of the nose was performed.
Results and conclusions:PMMA promoted the recovery of facial and nasal esthetic characteristics of the patient ensuring a satisfactory result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
