Hemifacial microsomia. A case report and review

Area of Science:

• Craniofacial surgery
• Plastic surgery
• Pediatric dentistry

Background:

• Hemifacial microsomia (HFM) is a congenital disorder characterized by underdevelopment of the first and second branchial arches, leading to asymmetric facial deformities.
• Treatment for HFM is highly individualized due to its variable presentation, ranging from functional appliances to complex reconstructive surgeries.
• Understanding the spectrum of HFM and its management is crucial for effective patient care.

Observation:

• A case of mild Hemifacial Microsomia (HFM) type I with unilateral hypoplasia was observed.
• The deformity involved underdeveloped structures derived from the first and second branchial arches.
• The patient presented with mild asymmetry, indicating a less severe form of the condition.

Findings:

• Onlay bone grafting was utilized as the primary treatment modality for this mild HFM case.
• The surgical intervention aimed to address the hypoplasia and improve facial contour and symmetry.
• Post-operative assessment indicated successful restoration of the affected facial structures.

Implications:

• Onlay bone grafting can be an effective treatment option for mild Hemifacial Microsomia (HFM) type I.
• This approach offers a less invasive alternative for managing specific craniofacial asymmetries.
• Further research into long-term outcomes of bone grafting in HFM is warranted.
