Thirty-two patients with nasal dermal sinuses and cysts were treated during the 10-year period from 1978 to 1987. These patients presented with midline cysts (N = 18) or sinus ostia (N = 14). Only 6 of the 32 patients manifested intracranial extension (19 percent). All the patients with intracranial extension exhibited an intracranial mass on preoperative CT scans. Ten patients with no CT evidence of intracranial mass were noted to have only a fibrous cord extending to the base of the foramen cecum. In 4 of these 10 patients, craniotomy confirmed that there was no intracranial extension of the dermoid. Four other patients presented with sinus ostia at the base of the columella. None of these 4 patients had intracranial extension. Clinical examination and preoperative CT scans provide most of the information needed to determine the nature, course, and extent of these lesions.
1978年至1987年的10年间，对32例鼻皮样囊肿和鼻窦囊肿患者进行了治疗。这些患者表现为中线囊肿（n = 18）或鼻窦开口（n = 14）。32例患者中只有6例出现颅内扩展（19%）。所有出现颅内扩展的患者在术前CT扫描中均显示有颅内肿块。10例CT检查无颅内肿块证据的患者被发现只有一条纤维索延伸至盲孔底部。在这10例患者中的4例，开颅手术证实皮样囊肿没有颅内扩展。另外4例患者在小柱基部有鼻窦开口。这4例患者均无颅内扩展。临床检查和术前CT扫描提供了确定这些病变的性质、病程和范围所需的大部分信息。
