Purpose:?Although papillary thyroid carcinoma metastases to the parapharyngeal space are rare, the high amount of fat tissue allows tumors to grow clinically undetectable until they invade most of the parapharyngeal space. We describe for the first time a combined endonasal and transcervical approach for a parapharyngeal metastasis from a papillary thyroid carcinoma. Materials and Methods:?A 51-year-old male with a previous history of papillary thyroid carcinoma presented with left ear fullness and left-sided facial numbness. Imaging revealed a 4x3 cm pre-styloid parapharyngeal space mass invading the foramen ovale and extending below the palate. Needle biopsy confirmed metastatic papillary thyroid carcinoma. Results:?The lesion was resected with a combined endoscopic endonasal and transcervical approach.?Postoperative MRI revealed gross total resection, and the patient recovered from his symptoms. Conclusion:?This novel approach provides access to pre-styloid parapharyngeal tumors with superior extension to the skull base, avoiding more extensive traditional open approaches.
