Transoral Robotic Surgery in Retrostyloid Parapharyngeal Space Schwannomas
Parapharyngeal space (PPS) tumors are very rare, representing about 0.5% of head and neck neoplasms. An external surgical approach is mainly used. Several recent papers show how transoral robotic surgery (TORS) excision could be a prospective tool to remove mainly benign lesions in PPS; no cases of neurogenic tumors from the retrostyloid space treated with TORS have been reported. We present tw...
متن کاملParapharyngeal Neck Schwannomas with Unusual Vascular Displacement
This case report illustrates two unusual cases of parapharyngeal schwannomas mimicking carotid body tumors in terms of characteristic vascular displacement. Carotid body tumors classically cause splaying of internal and external carotid arteries demonstrating the Lyre sign on imaging. Also interestingly, both of these cases were seen in younger ages and include cervical sympathetic chain schwan...

متن کاملParapharyngeal space synovial sarcoma.
Synovial sarcoma is a rare soft tissue sarcoma that commonly involves the lower extremities and occurs predominantly in young adults. It very rarely occurs in the head and neck region and carries a poor prognosis. The tumor demonstrates both a loco-regional and a systemic pattern of spread that makes management challenging. Combined modality therapy of this aggressive tumor yields better result...
