Aesthetic Management of an Atypical Lip Malformation - Report of Two Cases

Double lip deformity is a rare congenital or acquired anomaly characterized by the presence of redundant mucosal folds in the upper or lower lip, often more pronounced in the upper lip. This condition may manifest as a cosmetic concern rather than a functional impairment. Though typically asymptomatic, the deformity becomes evident during smiling or speaking, leading to patient discomfort or self-consciousness. The etiology of double lip deformity can be congenital, linked to developmental anomalies of the lips, or acquired, often associated with habits such as lip sucking, trauma, or conditions such as Ascher syndrome. The clinical presentation involves excess lip tissue appearing as a fold or double layer, particularly in the upper lip. Diagnosis is primarily clinical, based on visual examination and patient history, with no additional imaging typically required. This case report reviews multiple patients who presented with double lip deformity, focusing on its clinical characteristics, psychosocial impacts, and treatment approaches. Surgical excision is the preferred treatment for those seeking correction, especially for aesthetic reasons. This procedure is minimally invasive and generally yields excellent cosmetic results with low recurrence rates.
