Insights
Congenital Hemifacial Hyperplasia (CHH) causes unilateral facial overgrowth, often noticeable at birth and worsening during puberty. This case highlights diagnostic approaches and multidisciplinary management for this rare condition.
Area of Science:
- Craniofacial anomalies
- Developmental biology
- Genetics
Background:
- Congenital Hemifacial Hyperplasia (CHH) is a rare condition causing unilateral facial overgrowth.
- Facial asymmetry is typically evident at birth and progresses during puberty.
- Etiological factors include genetic, chromosomal, environmental, and endocrine influences.
Purpose of the Study:
- To present a case of CHH with detailed orofacial features.
- To supplement existing clinical knowledge on this rare condition.
- To emphasize diagnostic and management strategies.
Main Methods:
- Clinical case presentation.
- Detailed orofacial examination.
- Diagnostic investigation procedures.
Main Results:
- The case presented typical features of CHH, including progressive unilateral facial enlargement.
- Diagnostic investigations confirmed the diagnosis.
- The importance of a multidisciplinary approach was highlighted.
Conclusions:
- CHH requires a periodic and multidisciplinary approach for accurate diagnosis and management.
- Early recognition and intervention are crucial for optimal outcomes.
- This case contributes to the understanding of CHH's clinical presentation and management.
Abstract:
Hemifacial hyperplasia is a rare congenital malformation characterized by noticeable unilateral excess development of hard and soft tissues of the face. Asymmetry in Congenital Hemifacial Hyperplasia (CHH) is usually evident at birth and accentuated at the age of puberty. The affected side grows exponentially as compared to the unaffected side. Multiple tissue involvement has resulted due to etiological heterogeneity like heredity, chromosomal abnormalities, altered intrauterine environment, and endocrine dysfunctions. As this lesion is rarely seen in our routine clinical practice, we present a case of hemifacial hyperplasia with reported orofacial features that supplement existing clinical knowledge. This paper also adds knowledge to the readers regarding detailed investigation procedures which has complemented our diagnosis. Further emphasis has been placed on periodic approach to its diagnosis and multidisciplinary management following correct diagnosis.
