“…Wang et al have reported that although PPS tumors may be completely removed by both external and transoral endoscopic approaches, the latter has the advantages of reduced blood loss and postoperative pain level and preservation of facial cosmetic. Similar results have been reported by Fan et al Endoscope‐assisted transoral resection provides a wider view, reducing the risks of neurovascular injury or capsule rupture and allowing resection of large tumors; those tumors surrounded major vascular structures or with large lateral extension are not suitable. Endoscopy may also be used to overcome some of the limitations of external conventional approaches .…”

Contemporary management of primary parapharyngeal space tumors

The parapharyngeal space is a complex anatomical area. Primary parapharyngeal tumors are rare tumors and 80% of them are benign. A variety of tumor types can develop in this location; most common are salivary gland neoplasm and neurogenic tumors. The management of these tumors has improved greatly owing to the developments in imaging techniques, surgery, and radiotherapy. Most tumors can be removed with a low rate of complications and recurrence. The transcervical approach is the most frequently used. In some cases, minimally invasive approaches may be used alone or in combination with a limited transcervical route, allowing large tumors to be removed by reducing morbidity of expanded approaches. An adequate knowledge of the anatomy and a careful surgical plan is essential to tailor management according to the patient and the tumor. The purpose of the present review was to update current aspects of knowledge related to this more challenging area of tumor occurrence.

“…CT can clearly depict the bone destruction and the relationship between the tumor and the pterygoid process. However, MRI is more sensitive and specific for differentiating benign and malignant diseases than CT, and provides more information . The coronal image demonstrates the position of PPS neoplasms and the relationship between PPS neoplasms and the hard palate clearly.…”

Background: Surgery remains the mainstay of treatment for lesions in the parapharyngeal space. However, gaining access to the parapharyngeal space is o en challenging. In this study we aim to describe a minimally invasive technique of approaching the upper parapharyngeal space through an endoscopic transnasal retropterygoid approach, based on anatomic studies and surgeries. Methods:Six fresh human cadaver heads were prepared for anatomic study at the Surgical Neuroanatomy Laboratory of the Center for Cranial Base Surgery within the Department of Neurological Surgery at the University of Pi sburgh School of Medicine. Three clinical cases seen in the Department of Otolaryngology, Eye, Ear, Nose, and Throat Hospital, Shanghai Medical College of Fudan University, were used to illustrate the technique and feasibility of this approach and to assess its indications, advantages, and drawbacks. Results:The medial pterygoid plate is the primary landmark of the endoscopic transnasal retropterygoid approach to the upper parapharyngeal space. Access to the upper parapharyngeal space could be obtained by removing the mucosa on the medial pterygoid plate and the mucosa below the pharyngeal orifice of the Eustachian tube. The 3 patients in our study tolerated the procedure well and had no serious complications a er surgery. Conclusion:The anatomic data and clinical cases in this study confirm that an endoscopic transnasal retropterygoid approach is a feasible and effective surgical treatment for selected tumors in the upper parapharyngeal space.

“…The purely transoral/transpharyngeal approaches are well known and widely used, especially in the treatment of benign deep lobe parotid tumors. Some reports have also focused on the possibility of improving visualization of the transoral surgical field with endoscopic assistance, thus enabling better identification of anatomic structures and improvements in tumor dissection with reduced risk of neurovascular injury or capsular rupture . When dealing with malignancies, however, the exclusive transoral approach should be limited to very selected lesions of the prestyloid compartment without superior extension toward the skull base or lateral extension beyond a virtual sagittal plane passing through the parapharyngeal tract of the ICA.…”
