Temporal hollowing, which is a depression in the temple region, often results from trauma, surgical interventions, or neurological conditions. This condition is frequently observed after the resection of encephaloceles, where it can cause esthetic and functional challenges due to temporalis muscle atrophy and nerve palsy. We present a case of a 21-year-old female patient who developed temporal hollowing and complete atrophy of the right temporalis muscle following an encephalocele resection in childhood. The patient also suffered from right-sided frontal nerve branch palsy. To address this complex deformity, a patient-specific implant (PSI) made of hydroxyapatite (HA) was digitally designed and produced using 3D printing technology. The postoperative course was uneventful, with the implant securely positioned and the esthetic result highly satisfactory. This case highlights the potential of 3D printed PSIs in craniofacial reconstruction, offering an optimal solution for both functional restoration and esthetic enhancement. HA further ensures the long-term stability and integration of the implant, providing a promising approach for addressing complex craniofacial defects.
颞部凹陷，即颞区的凹陷，通常由外伤、手术干预或神经疾病引起。这种情况在脑膨出切除术后经常出现，由于颞肌萎缩和神经麻痹，会导致美观和功能方面的问题。我们报告一例21岁女性患者，她在童年时期接受脑膨出切除术后出现了颞部凹陷和右侧颞肌完全萎缩。该患者还患有右侧额神经分支麻痹。为了解决这种复杂的畸形，使用3D打印技术对由羟基磷灰石（HA）制成的定制植入物（PSI）进行了数字化设计和制作。术后过程顺利，植入物位置固定，美观效果非常令人满意。该病例突出了3D打印PSI在颅面重建中的潜力，为功能恢复和美观改善提供了最佳解决方案。HA进一步确保了植入物的长期稳定性和整合性，为解决复杂的颅面缺陷提供了一种有前景的方法。
