ABSTRACT
The parapharyngeal space is defined by fascial planes and very vulnerable to neoplastic extension. The schwannoma in parapharyngeal space is rare. It grows slowly, but can produce various symptoms and signs according to it’s origin and size.
Carotid angiography combined with CT scan and MRI provide crucial information for adequate surgical approaches. Antoni type A and B, Verocay body is shown in histologic examination.
The correct surgical approach depends upon the careful preoperative differentiation of parotid tumors from extraparotid pharyngeal tumors.
We experienced one case of schwannoma in the parapharyngeal space in 38-year-old woman.
This case was treated through cervicomandibular approach without osteotomy on mandible.
Keywords: Parapharyngeal space tumor; Schwannoma
