Nasal mucosal melanoma (NMM) is a rare tumor with a poor prognosis. Although an endoscopic resection of malignant nasal tumor now becomes a treatment of choice when the surgical margin can be secured, it is still controversial. We report three cases of NMM that was successfully removed en bloc with clear margins by endoscopic surgery with temporal transseptal access. Cases of a 78-year-old woman, an 83-year-old man, and an 81-year-old man with NMM arising from the inferior turbinate who underwent endoscopic resection of the tumor are discussed in detail. We made temporal transseptal access using septal mucosal flaps. We moved the nasal cavity-occupying tumor to the contralateral side to create a working space to perform endoscopic en bloc resections. This technique is simple yet effective and less invasive than open craniofacial resections for removing malignancies arising from the inferior turbinate.
鼻黏膜黑色素瘤（NMM）是一种预后较差的罕见肿瘤。尽管当手术切缘能够确保时，内镜下切除鼻腔恶性肿瘤目前已成为一种治疗选择，但仍存在争议。我们报告了3例通过经颞中隔入路的内镜手术成功整块切除且切缘清晰的NMM病例。详细讨论了1例78岁女性、1例83岁男性和1例81岁男性因下鼻甲发生NMM而接受肿瘤内镜切除术的病例。我们使用鼻中隔黏膜瓣进行经颞中隔入路。我们将占据鼻腔的肿瘤移至对侧，以创造一个工作空间来进行内镜下整块切除。该技术简单有效，与开放性颅面切除术相比，对于切除下鼻甲来源的恶性肿瘤侵袭性更小。
