The endoscopic transnasal maxillary sinus approach is usually performed in resecting tumors located in the pterygopalatine fossa and infratemporal fossa, but is rarely used in the resection of lesions in the middle cranial fossa. Because of the complicated anatomical structure of the middle cranial fossa, trigeminal schwannomas (TSs) located in this region are usually dissected through conventional craniotomy surgical approaches; however, the endoscopic transnasal maxillary sinus approach can be used in resection of middle cranial fossa TSs. The current study presented the case of a 59-year-old man who suffered intermittent headaches for 2 years without other notable medical history and neurological abnormalities. The patient was diagnosed with a middle cranial fossa TS. After imaging and assessment of anatomical features, the tumor was totally resected through the transnasal maxillary sinus approach. Following surgery, the symptoms were relieved and the patient returned to a normal life. Light numbness was complained of in the distribution area of the maxillary nerve of the right side of the face, but this was gradually relieved. Combined with a literature review, the present case indicated that the endoscopic transnasal maxillary sinus approach may provide a safer and more direct option for resecting middle cranial fossa lesions, which is worthy of increased clinical application.
鼻内镜经鼻上颌窦入路通常用于切除位于翼腭窝和颞下窝的肿瘤，但很少用于切除中颅窝的病变。由于中颅窝解剖结构复杂，位于该区域的三叉神经鞘瘤（TSs）通常通过传统开颅手术方法进行切除；然而，鼻内镜经鼻上颌窦入路可用于中颅窝TSs的切除。本研究报告了一例59岁男性患者，该患者间歇性头痛2年，无其他明显病史及神经功能异常。患者被诊断为中颅窝TS。经影像学检查及解剖结构评估后，通过经鼻上颌窦入路将肿瘤完全切除。术后症状缓解，患者恢复正常生活。患者右侧面部上颌神经分布区有轻度麻木感，但逐渐缓解。结合文献复习，本病例表明鼻内镜经鼻上颌窦入路可能为切除中颅窝病变提供一种更安全、更直接的选择，值得临床更多应用。
