The parapharyngeal space is a complex and well-defined anatomical zone lying lateral to the pharynx and medial to the ramus of the mandible. Although tumors of this space are rare, the parapharyngeal space is difficult to examine clinically; and diagnostic modalities of computerized tomographic scanning and magnetic resonance imaging are primarily used in the evaluation of parapharyngeal space lesions. We present a case report of a second branchial cleft sinus of the parapharyngeal space diagnosed with the assistance of fine needle aspiration (FNA), and we recommend FNA of parapharyngeal masses to provide definitive preoperative diagnoses.
咽旁间隙是一个位于咽腔外侧和下颌骨升支内侧的复杂而明确的解剖区域。尽管该区域的肿瘤较为罕见，但临床上很难对其进行检查；因此，计算机断层扫描和磁共振成像等诊断方法主要用于评估咽旁间隙病变。我们报告了一例在细针抽吸（FNA）协助下诊断的咽旁间隙第二鳃裂窦，并建议对咽旁肿块进行 FNA，以提供明确的术前诊断。
