Schwannoma of the parapharyngeal space.
A schwannoma (or neurilemmoma) of the parapharyngeal space is a rare tumor in the head and neck region arising from the sheath of cranial nerves and/or the sympathetic chain. In the early stages of growth, there is usually a lack of symptoms because of the anatomical localization and slow growth of the tumor. The large dimension of the mass at presentation makes it difficult to perform a functional surgery, and in many cases the operation worsens the nerve status. The choice of surgical approach is of paramount importance in both preserving nerve function and achieving vascular control. The authors report a case and discuss the English literature.
