Transoral videolaryngoscopic surgery （TOVS） for the parapharyngeal space and retropharyngeal space

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...

Transoral approach to the superomedial parapharyngeal space.

OBJECTIVES To present our early experience with the transoral approach to the superomedial parapharyngeal space (PPS) and describe our technique for removal of these neoplasms. STUDY DESIGN Consecutive case series by one author (Y.D.). METHODS Eight patients with various neoplasms of the superomedial PPS were retrospectively reviewed for type of neoplasm, size, success with the transoral ap...

Ultrasound-Guided Transoral Videolaryngoscopic Surgery for Retropharyngeal Lymph Node Metastasis of Papillary Thyroid Cancer

BACKGROUND Endoscopic-assisted transoral surgery, including transoral robotic surgery for metastatic retropharyngeal lymph node (RPN) from well-differentiated thyroid cancer, has been reported to reduce the complications resulting from transcervical and transmandibular approaches. However, the narrow working space and difficulty identifying RPN are problematic. To solve these issues, several st...

Transoral videolaryngoscopic surgery with a navigation system for excision of a metastatic retropharyngeal lymph node.

OBJECTIVES To report the utilization of a new transoral surgery system, i.e. transoral videolaryngoscopic surgery (TOVS) with a navigation system, for the removal of a metastatic retropharyngeal lymph node (RPLN). CASE REPORT An 86-year-old woman with tongue cancer (cT2N0M0) underwent partial glossectomy and left selective neck dissection. Three months postoperatively, a left metastatic RPLN ...
