Although approximately 13% of lipomatous tumors occur in the head and neck, most of these are found in the immediate subcutaneous tissues, and lipomas of the deep head and neck tissues are rare. Lipomas consist of adipose tissue separated by fine fibrous trabeculae; if the amount of fibrous tissue is appreciable, the designation of fibrolipoma is used. We describe an unusual case of a parapharyngeal fibrolipoma with airway narrowing and ipsilateral compromise of the carotid artery and internal jugular vein blood flow. Diagnosis of deep head and neck lipomata is facilitated by utilizing computed tomographic analysis and angiography. The transcervical approach to the skull base which allows complete resection of this lesion is described.
尽管约13%的脂肪瘤性肿瘤发生于头颈部，但其中大多数位于紧邻的皮下组织，而深部头颈部组织的脂肪瘤较为罕见。脂肪瘤由被纤细纤维小梁分隔的脂肪组织构成；如果纤维组织量可观，则称为纤维脂肪瘤。我们描述了1例罕见的咽旁纤维脂肪瘤病例，该肿瘤导致气道狭窄，并使同侧颈动脉和颈内静脉血流受到影响。利用计算机断层扫描分析和血管造影有助于诊断深部头颈部脂肪瘤。本文还描述了经颈部入路至颅底，从而能够完整切除该病变的方法。
