Which degenerative disorder is characterized by atrophy of deep facial structures (including fat, muscle, cartilage, and bone) restricted to one side of the face:
Show answer Hide answer
Answer: B. Parry Romberg syndrome
Explanation
Parry-Romberg syndrome involves progressive hemifacial atrophy restricted to one side of the face. The degenerative condition causes wasting of deep facial structures including fat and muscle. Cartilage and bone tissues on the affected side experience progressive developmental deterioration. The exact etiopathogenesis of Parry-Romberg syndrome remains poorly understood by medical researchers. Skin changes often include hyperpigmentation or localized areas of depressed dermal atrophy. Onset typically occurs during childhood or early adolescence before stabilizing spontaneously.
Plastic surgery and fat grafting are utilized to correct facial asymmetry in patients. Ophthalmologic complications can arise due to progressive orbital fat and tissue loss. Early diagnosis helps manage psychological impacts associated with progressive facial disfigurement. Scleroderma causes generalized or localized skin thickening and fibrosis rather than hemiatrophy. Miescher syndrome involves granulomatous cheilitis associated with Melkersson-Rosenthal clinical conditions. Peutz-Jeghers syndrome is characterized by gastrointestinal polyposis and mucocutaneous pigmentation spots.
