Abstract

Objectives/Hypothesis:

Parapharyngeal space (PS) tumors are surrounded by critical anatomical structures. Resection is often challenging due to limited surgical exposure. Herein, we report a novel transcervical, minimally invasive, video-assisted technique that facilitates the resection of PS lesions.

Study Design:

Case series and review of literature.

Methods:

Description of surgical technique with analysis of four cases and literature review.

Results:

The technique combines a transcervical approach to the PS and skull base with video-assisted and image-guided dissection of tumor. Four cases of benign PS tumors resected with this technique are reported. The size of the tumor excised varied between 0.9 cm and 5 cm. Estimated blood losses were minimal. The average length of hospital stay was 1.5 days. No permanent complications were encountered.

Conclusions:

Excision of PS tumor abutting the skull base using a novel minimally invasive, video-assisted, image-guided, transcervical approach is feasible and safe. The short hospitalization stay and low morbidity makes it well suited for the resection of benign PS lesions.
