Parapharyngeal space (PPS) tumours, most of them benign, account for some 0.5% of tumours of the head and neck. The importance of these tumours lies mainly in two aspects: on the one hand, the difficulty of early diagnosis, due to the lack of symptoms in the initial stages and, on the other, the extreme complications of performing surgery in the parapharyngeal region. This article discusses two clinical cases of parapharyngeal space tumours: a 45 year old man and a 60 year old woman. We revise the scientific literature and analyse the diagnostic and therapeutic procedures used, placing special emphasis on describing the different surgical approaches to the parapharyngeal space: transcervical, transcervical-transparotid, transpalatal or transoral, transmandibular and orbitozygomatic, all of which, used alone or combined with others, allow for complete resection of these tumours with minimum morbidity.
咽旁间隙（PPS）肿瘤大多为良性，约占头颈部肿瘤的0.5%。这些肿瘤的重要性主要体现在两个方面：一方面，由于初期缺乏症状，早期诊断困难；另一方面，在咽旁区域进行手术会引发极其严重的并发症。本文讨论了两例咽旁间隙肿瘤的临床病例：一名45岁男性和一名60岁女性。我们查阅了科学文献并分析了所采用的诊断和治疗方法，特别着重描述了针对咽旁间隙的不同手术入路：经颈入路、经颈-腮腺入路、经腭或经口入路、经下颌入路和眶颧入路，所有这些入路单独使用或与其他入路联合使用，都能在将发病率降至最低的情况下完整切除这些肿瘤。
