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.
耳部缺损患者使用耳部假体可受益匪浅。然而，在耳部假体制作过程中，可能会面临一些困难，难以获得满意的效果，比如假体撕裂、模具断裂以及颜色匹配不佳等问题。一名18岁男性在一次袭击事件中失去了部分左耳廓，这给他带来了不良的心理社会影响。由于患者的意愿和经济限制，手术重建被排除在外。采用四部分模具技术和分光光度计制作了部分耳部假体，取得了理想的效果。四部分模具技术防止了模具断裂，使假体取出更容易。分光光度计减少了患者就诊时间以及试错法进行颜色匹配所需的艺术技巧。
