BACKGROUND Head and Neck Parapharyngeal space tumors are rare. Pleomorphic Adenomas are the most common Parapharyngeal space tumors. The purpose of this study was to define preoperative criteria for enabling full extirpation of parapharyngeal space pleomorphic adenomas via the transcervical approach while minimizing functional and cosmetic morbidity. METHODS The surgical records and medical c...
BACKGROUND Conventional approaches for removing parapharyngeal space tumors require a cervical skin incision and resection of soft tissues between the skin and parapharyngeal space. The surgical visual field for this conventional approach is limited. METHODS To decrease invasiveness during removal of benign parapharyngeal space tumors and to enhance the visual field, we devised a new approach...
Parapharyngeal tumors are relatively rare tumors of head and neck. In general, pleomorphic adenoma is one of the most common benign tumor of the parapharyngeal region. Various approaches have been described in the literature for removal of parapharyngeal tumor with mandibulotomy generally carried out for large tumors. Here, we describe removal of a large parapharyngeal pleomorphic adenoma trans...
Tumors of the parapharyngeal space account for 0.5% of head and neck neoplasms. The parapharyngeal space is actually a potential space located lateral to the upper pharvnx. This bilateral fat containing region extends from the skull base to the hyoid bone. The parapharyngeal space is further compartmentalized by thick fascial layers that direct tumor growth. Among the salivary gland neoplasms, ...
BACKGROUND Preliminary case series have reported clinical feasibility and safety of a transoral minimally invasive technique to approach parapharyngeal space masses. With the assistance of the surgical robotic system, tumors within the parapharyngeal space can now be excised safely without neck incisions. A detailed technical description is included. METHODS After developing compressive sympt...
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 ...
Fig, 1,-25-year-old man with parapharyngeal angiofibroma. A, Unenhanced axial CT scan shows a mass (arrows) in parapharyngeal space, with anterior displacement and splaying of pterygoid plates. B, Enhanced coronal CT scan shows an enhancing left-sided parapharyngeal mass (arrows) displacing pharynx toward right. C, Angiogram of left common carotid artery shows a hypervascular mass (arrows) supp...
PURPOSE To subclassify parapharyngeal extension in nasopharyngeal carcinoma (NPC) and investigate its prognostic value and staging categories based on magnetic resonance imaging (MRI). METHODS AND MATERIALS Data from 1504 consecutive NPC patients treated with definitive-intent radiotherapy were analyzed retrospectively. Sites of parapharyngeal extension were defined by MRI. Overall survival (...
Parapharyngeal pleomorphic adenoma (PA) is a benign tumor of the salivary glands. We report a rare case of giant benign parapharyngeal PA with intracranial extension in a 69-year-old male who presented with aural fullness. Magnetic resonance imaging (MRI) showed a large, lobulated, well-defined mass in parapharyngeal space with erosion of the base of the middle cranial fossa and extension to th...
This report presents a 55-year-old woman who underwent 2 Teflon injections in 1971 for a patulous eustachian tube. The patient returned in 2006 with a bloody left otorrhea. A positron-emission tomography-CT scan demonstrated a 2-cm hypermetabolic parapharyngeal mass, initially interpreted as a skull base tumor. Repeat neck CT confirmed a 2-cm hyperattenuated left parapharyngeal granulomatous ma...
