Sequential treatment for a patient with hemifacial microsomia: 10 year-long term follow up.

Seo JS, Roh YC, Song JM, Song WW, Seong HS, Kim SY, Hwang DS, Kim UK - Maxillofac Plast Reconstr Surg (2015)

Bottom Line: In patients with HFM, the management of the asymmetries requires a series of treatment phases that focus on their interception and correction, such as distraction osteogenesis or functional appliance treatment during growth and presurgical orthodontic treatment followed by mandibular and maxillary surgery.At the age of 19, genioplasty and mandible body augmentation with a porous polyethylene implant (PPE, Medpor®, Porex) was sequentially performed for the functional and esthetic reconstruction of the face.We report a case of HFM with a review of the literature.

ABSTRACT

Hemifacial microsomia (HFM) is the most common craniofacial anomaly after cleft lip and cleft palate; this deformity primarily involves the facial skeleton and ear, with either underdevelopment or absence of both components. In patients with HFM, the management of the asymmetries requires a series of treatment phases that focus on their interception and correction, such as distraction osteogenesis or functional appliance treatment during growth and presurgical orthodontic treatment followed by mandibular and maxillary surgery. Satisfactory results were obtained in a 9-year-old girl with HFM who was treated with distraction osteogenesis. At the age of 19, genioplasty and mandible body augmentation with a porous polyethylene implant (PPE, Medpor®, Porex) was sequentially performed for the functional and esthetic reconstruction of the face. We report a case of HFM with a review of the literature.

Fig2: Pre-operative model surgery with DO device.

Mentions: Preoperative orthodontic treatment was administered at the age of 10 years to correct posterior openbite at the Department of Orthodontics. DO was initiated when the patient was 12 years old. The amount of horizontal and vertical DO was measured on an RP model prior to the procedure (Figure 2). From the model analysis, the required horizontal and vertical bony lengths measured were 3 mm and 16 mm, respectively. The estimated vector angle for DO was 12° from the mandibular angle. The operation included an incision on the left mandibular posterior vestibule; the lateral surface of the left mandibular body and ramus were also exposed. Furthermore, a lateral and medial corticotomy was performed at the lateral angle of the mandible, in order to create a complete greenstick fracture. An extraoral mandibular distraction device was also installed on both segments of the ramus, with the aid of screws (Leibinger, Multi-guide 2®, Switzerland) (Figure 3).Figure 2
