CURRENT APPROACHES TO MANAGING MICROTIA

Abstract

Microtia, a developmental anomaly of the external ear resulting in a deformed auricle, affects 1 to 5 individuals per 10,000. Literature suggests a male predominance, with nearly 2.5 times more male patients affected than females. Additionally, there is a notable right-sided predilection, leading to pronounced asymmetry, observed in approximately 83% of cases. Surgical reconstruction is the primary treatment for microtia, albeit a technically demanding procedure with challenges in achieving optimal aesthetic outcomes. Reconstruction typically involves autologous costal cartilage, known for its effectiveness but requiring advanced surgical skills. Complications, including pneumothorax, postoperative pain, chest wall deformity, and pathological scarring, are common with this approach. In recent years, surgeons have increasingly adopted modern techniques utilizing porous high-density polyethylene implants for reconstruction. This approach is gaining popularity due to the challenges associated with achieving satisfactory cosmetic results using autologous costal cartilage reconstruction. Based on the bibliosemantic and analytical methods employed to analyze the literature, we posit that this topic necessitates further investigation and a multidisciplinary approach. The involvement of otolaryngologists and maxillofacial surgeons is imperative for the comprehensive treatment of this pathology.
