Acquired partial auricular defect rehabilitation aided by four-part mold technique and spectrophotometer.

Patients with auricular defects benefit greatly by an ear prosthesis. However, during the fabrication of auricular prosthesis, difficulties can be faced in obtaining a satisfactory outcome, such as tearing of the prosthesis, fracture of the mold and poor color matching. An 18 year old male lost part of his left auricle in an assault and battery because of which the patient was suffering from adverse psychosocial impact. Surgical reconstruction was ruled out because of patient's desire and financial constraints. Partial auricular prosthesis using four part mold technique and spectrophotometer was fabricated leading to a desirable outcome. Four part mold technique prevented fracture of mold and made retrieval of prosthesis easier. Spectrophotometer reduced the duration of patient visit and the artistic skill required for colour matching in tral and error method.

Reconstrucción de una pérdida parcial del pabellón auricular por trauma / Reconstruction of a partial traumatic auricular loss

La posición expuesta de la oreja la hace vulnerable a muchos tipos de lesiones, entre las que se encuentran los traumas. Nuestro propósito es presentar un caso clínico en el que se realizó la reconstrucción de una pérdida parcial del pabellón auricular por trauma. Acude al cuerpo de guardia del Hospital Universitario General Calixto García un paciente masculino de 42 años refiriendo haber perdido un fragmento de oreja en una riña. Se decide realizar hemostasia y fijación mediante puntos de sutura del pabellón auricular remanente a la región temporal, previa incisión en la zona. A los 3 meses del evento traumático se reevalúa con fines de realizar la planificación preoperatoria reconstructiva. Se decide la realizarla mediante injerto de cartílago costal colocado en forma de bolsillo en la región temporal. Al mes de esta última intervención quirúrgica se realiza, bajo anestesia local, la liberación de la región auricular, el avance de un colgajo temporal y la colocación de un injerto libre de piel en la cara posterior del área reconstruida. Se observa una excelente evolución posoperatoria. El paciente refirió una gran satisfacción por los resultados estéticos obtenidos. En este caso se empleó una secuencia diagnóstica y terapéutica, según elección de los cirujanos involucrados, ante un defecto traumático parcial del pabellón auricular en sus tercios superior y medio. Este tipo de secuela traumática requirió el empleo de procederes quirúrgicos en varios tiempos operatorios que garantizaran un buen aporte sanguíneo de los tejidos y adecuados resultados estéticos finales(AU)

The exposed position of the ear makes it vulnerable to many types of injuries, including traumas. It is our purpose to present a clinical case in which reconstruction was performed of a partial traumatic auricular loss. A 42-year-old male patient presents at the emergency service of General Calixto García University Hospital and reports having lost a piece of his ear in a fight. It was decided to perform hemostasis and fixation by stitching the remaining section of the auricle to the temporal region, after making an incision in the area. Three months after the traumatic event re-evaluation was conducted with a view to planning reconstructive surgery. It was decided to carry out the reconstruction placing a pocket-shaped rib cartilage graft in the temporal region. One month after the operation, auricular release, advancement of a temporary flap and placement of a free skin graft on the back of the reconstructed area were performed under local anesthesia. Excellent postoperative evolution was observed. The patient reported great satisfaction with the esthetic results obtained. The case herein presented was based on a diagnostic and therapeutic sequence of actions determined by the surgeons involved with a view to correcting a partial traumatic defect of the upper and middle thirds of the auricle. This type of traumatic sequel required the use of surgical procedures at several operative moments ensuring good blood supply to tissues and appropriate final esthetic results(AU)
