Reconstruction of facial hemiatrophy using calcium hydroxylapatite filler: report of a safe and minimally invasive technique

INTRODUCTION: Progressive Facial Hemiatrophy, also known as Parry Romberg Syndrome, is a rare form of linear scleroderma. The management of facial atrophy sequelae is challenging.
OBJECTIVE: This study aims to evaluate for the first time in literature the effectiveness of the calcium hydroxylapatite (CaHa) filler in the jawline reshaping of a patient with Parry Romberg Syndrome.
CASE REPORT: A 15-year-old woman with progressive atrophy of the right side of the face due to Parry Romberg Syndrome. After disease control, the patient’s main complaint was facial asymmetry, mainly in the jawline region.
DISCUSSION: CaHa is a biocompatible injectable filler that is gradually resorbed and replaced by fibrovascular stroma, mainly formed for new collagen, in a process that occurs without any immunological reaction. This safety profile makes CaHa a good choice for correcting stable scleroderma defects.
CONCLUSION: This report concludes that CaHa filler biocompatibility and suitability for the jawline correction are also applicable in reconstructive procedures for stable scleroderma, safely and minimally invasively, with optimal aesthetic results. The method must be programmed case-by-case, and a regular follow-up is also recommended.
