Transoral robotic resection of selected parapharyngeal space tumors.
Currently, transoral robotic surgery (TORS) with the daVinci robot is mainly used for squamous cell carcinoma of the oropharynx and supraglottic larynx. The safety, efficacy, and functional outcomes regarding this approach have previously been described. In addition to transoral resection of squamous cell carcinoma, we have found use for this technique in removing selected tumors of the parapharyngeal space. Three patients with benign or malignant tumors of the parapharyngeal space who underwent successful transoral resection using the daVinci robot were included in the study. In all three cases, complete tumor excision was achieved without any complication. None required conversion to an open procedure. Mean TORS operative time and intraoperative blood loss were 16.3 min and 4.7 mL, respectively. Inadequate oral exposure, involvement of the internal carotid artery, limited cervical spine mobility and large tumor size are the main limitations of this approach. Result indicates that magnified view, 3D visualization with the combination of the transoral robotic experience, allow en bloc resection of selected parapharyngeal space tumors located medial to the carotid sheath.
