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)

Gender effect on the preoperative cardiovascular responses in pediatric patients undergoing two-stage ear reconstruction surgery for microtia

BACKGROUND: The hemodynamic reactions to psychological stress were different between adult genders. Our aim was to investigate the hypothesis that preoperative cardiovascular responses in children undergoing ear reconstruction surgeries will be different according to gender. METHODS: We obtained data from children, aged 7-16 years, undergoing reconstruction surgeries for microtia during 2005-2009. Number of boys receiving primarily rib cartilage graft (RCG) surgery and secondarily ear elevation procedure was 121 and 83, respectively, and girls 48 and 28, respectively. Preoperative systolic (S), diastolic blood pressure (DBP) and heart rate (HR) on each surgery were compared between genders, and within genders. RESULTS: Boys were younger than girls by one year at first and second admission. Boys showed significantly lower preoperative DBP than girls (mean difference [MD]: -3.7 mmHg, 95%CI: -6.1 to -1.3, P = 0.032) before RCG, whereas significantly higher SBP (MD: 21.5 mmHg, 95%CI: 16.6 to 26.4, P < 0.001), and DBP (MD: 10.2 mmHg, 95%CI: 6.0 to 14.4, P < 0.001) before ear elevation. Comparison between the two surgeries within the same gender indicated that boys demonstrated significantly higher SBP (P < 0.001) and DBP (P < 0.001) before ear elevation than before RCG; however SBP was comparable and DBP was significantly lower (P = 0.035) before ear elevation than before RCG in girls. CONCLUSIONS: Gender impact on the preoperative cardiovascular reactions was evident in children undergoing microtia surgery.

Complications in the Recipient Sites of Autologous Rib Cartilage Grafts for Microtia

PURPOSE: Microtia is a congenital anomaly resulting from abnormal development of the branchial apparatus. Although significant modification and improvement of operative procedures for the reconstruction of the auricle with a natural appearance have been reported, postoperative complications, such as infection, flap necrosis and deformity, still remain serious problems in patients. Many studies with long-term results have focused mainly on operative procedures for an acceptable auricular shape without consideration of possible complications. METHODS: We conducted a retrospective study on postoperative complications at the recipient sites of 183 patients who underwent auricular reconstruction with autologous rib cartilage grafts from November 1987 to January 2007 at the Division of Pediatric Plastic Surgery, Seoul National University Children's Hospital. Patients were analyzed in terms of the kinds and incidences of complications, and their treatment options. RESULTS: Postoperative complications included wound dehiscence, flap necrosis, infection, hypertrophic scar, auricular deformity and absorption of rib cartilage grafts. The complications occurred in 47 patients with a complication rate of 25.7%. Fourteen patients were successfully managed with conservative treatment. However, surgical treatment was required in 51 reoperations(33 patients) of total 329 operations. CONCLUSION: Postoperative complications at the recipient sites of autologous rib cartilage grafts occurred with relatively high incidences and required long-term treatments and multiple surgeries. The results of this study may provide information on the causes and proper management of postoperative complications as well as safe procedures for the reconstruction of the auricle.

Correction of Constricted Ear

The constricted ear was suggested by Tanzer for the purpose of obviating the confusion involving lop ear, cup ear and prominent ear as defect whose helix turns down, and scapha and fossa triangularis are narrowed. The constricted ear has a spectrum of severity and therefore, requires a graded surgical approach. Tanzer has described the degree of deformities of the constricted ear as falling into three groups. For the correction of constricted ear, there are numerous techniques but we have had difficulties in adopting these techniques in various type. We also describe the various constricted ear as the Tanzer's classification and adopted three methods to each type, banner flap(group I), concha cartilage graft (group II) and rib cartilage graft(group III) for reducing postoperative deformity and confusion in correcting the ear deformities. Constricted ear repairs must be individualized to accomodate each specific deformity. We corrected 22 cases of constricted ear in 20 patients using each optimal method described above according to the degree of deformities. Mild deformities need only reshaping and adjusting of existing tissues, moderate deformities need additional skin and severe deformities require a cartilage graft. For correction of constricted ear, accurate identification of the severity of deformity is essential. The results were satisfactory and we report our experience with relative literatures.

Nasal deformities and their treatments in the leprosy patients (I) / 나학회지

Lepra bacilli invade the nasal mucosa from early stage. The infiltrated mucous membrane breaks down and ulcerates easily. Irritating crusts and ulcers occur, creating in perforation of the septum. When most of the septum and inner mucosal lining of the nose is destroyed, the nose is deprived of its support and it collapses. The nasal bones are typically intact, and the collapsed nose adheres to the facial skeleton, giving the characteristic 'sunken and short nose' deformities. We have operated on 25 patients with deformities such as short nose, sunken nose, collumela deformity and ala collapse since 1992. In short nose we operated with a paramedian forehead flap and rib cartilage graft in a cantilever pattern. In ala collapse we used a conchal cartilage graft. Lastly, in collumela deformity we used the local flap and a composite graft.
