The number of perioperative complications encountered in this series confirms the difficulty of performing surgery in this complex area, even in benign cases. Of such external approaches, transcervical and cervical/transparotid are the most often used in benign forms. Surgery is the mainstay treatment and external approaches offer the potential for satisfactory tumour resection. In conclusion, neurogenic tumours may be the most common of PPS masses. Follow-up, extended to a maximum of 11 years, did not reveal any recurrences. There was no operative mortality, though neurologic morbidity was significant. Four different approaches were adopted for tumour removal: transcervical, transcervical/transparotid, cervical-transparotid-transmandibular and infratemporal fossa approach. Most of the surgeries were planned through imaging alone, as preoperative fine needle aspiration (FNA) biopsy was performed only in six cases. Most contrast-enhanced masses were submitted to some type of angiography. Patients underwent preoperative computed tomography (CT) scan or magnetic resonance imaging (MRI) or both. All the tumours were benign in nature and gave rise to few signs or symptoms. There were 14 paragangliomas (7 originating from carotid glomus, 5 from vagal and 2 from tympanicum), 1 sympathetic chain schwannoma and 6 pleomorphic adenomas. The most common tumours found were neurogenic neoplasms, while those of salivary origin were the next most common. The retrospective review included 20 patients, 11 male and 9 female, average age of 41 years operated on for 21 primary PPS tumours. The diagnostic and therapeutic procedures performed in a series of patients with primary parapharyngeal space (PPS) tumours treated at the ENT Departments of San Giovanni Bosco Hospital, Turin, and of the Pugliese-Ciaccio Hospital, Catanzaro, Italy, in the period 2001-2010 are evaluated.
