The histologically benign hypopharyngeal lipoma is a potentially fatal tumour because of the risk of upper airway obstruction. It may be asymptomatic or present with symptoms ranging from vague foreign-body sensation to sore throat, dysphagia or dysphonia. The diagnosis may be suggested by indirect or fibreoptic laryngoscopy. Lateral neck soft tissue X-ray and barium swallow may help but CT imaging of the pharynx enables a more precise preoperative diagnosis. Treatment is by surgical excision of the lesion either perorally, endoscopically or via a lateral pharyngotomy. Long-term follow-up is recommended due to the possibility of recurrence and metachronous lesions.
组织学上为良性的下咽脂肪瘤是一种潜在的致命肿瘤，因为存在上呼吸道梗阻的风险。它可能无症状，或表现出从模糊的异物感至咽痛、吞咽困难或声音嘶哑等症状。间接喉镜检查或纤维喉镜检查可能提示诊断。颈部侧位软组织X线检查和吞钡检查可能有帮助，但咽部CT成像能实现更精确的术前诊断。治疗方法是经口、内镜或通过咽侧切开术对病变进行手术切除。鉴于存在复发和异时性病变的可能性，建议进行长期随访。
