A Huge Benign Laryngeal Fibrolipoma Causing Airway Compromise

在所有頭頸部腫瘤中，變大的腫瘤都具惡性的可能，巨大良性腫瘤是非常少見的，約有0.5%是長在咽喉旁的空腔內。脂肪瘤生長在咽喉旁空腔內非常少見，目前在醫學文獻中只有出現少數病例報告。本篇報告描述用開刀的方式來移除一個從右側咽喉空腔內生出的巨大脂肪瘤，此腫瘤從會厭的高度向下延伸至甲狀腺，因此在44歲的女性患者造成了呼吸、發聲、及吞嚥的困難，但卻沒有造成任何外觀的異常。當病人第一次來求診時，由喉頭鏡觀察到完整平滑的咽喉側壁有腫瘤壓迫的現象。核磁共振的檢查證實一個位於喉頭深部的巨大纖維脂肪瘤從會厭延伸至甲狀腺，因此造成了臨床上觀察到的呼吸道壓迫。此位置生出的良性巨大脂肪瘤非常少見。經過各項檢查後，決定用經頸切開的方式來切除腫瘤。手術中經由胸鎖乳突肌的前緣來分離側壁，而小部分的咽喉壁也一併切除以確保完整腫瘤的移除。術後追蹤病人6個月，並無觀察到任何復發及臨床併發症。

The majority of expanding neck masses have malignant potentials and, generally oversized benign tumors in this region are seldom seen. The incidence of tumors in the parapharyngeal space is about 0.5% of all head and neck tumors. Furthermore, only a few isolated cases have been published in the literature. In this case, a 44 year-old female patient with a normal external neck appearance was found to have, a neck fibrolipoma that had originated from the right parapharyngeal space, and then extended down to the upper tip of the thyroid capsule. The presence of the parapharyngeal tumor had produced clinical symptoms of dysphagia and dysphonia prior to its surgical removal. MRI confirmed that the fibrolipoma was embedded deeply in the parapharyngeal space and had caused compression of both pharyngeal and laryngeal wall. A transcervical approach operation from the anterior border of sternocleidomastoid muscle was performed and the operation included partial pharyngeal wall excision to ensure complete removal. The post-operative course was uneventful over a six month follow up period.
