Van Zele T, et al. - The efficacy of a novel, drivable endoscope (the Peregrine Drivable ENT Scope) vs standard rigid endoscopes in the access, visualization, and irrigation of the paranasal sinus anatomy was determined. In this prospective, multi-center, feasibility study of 17 patients who underwent primary functional endoscopic sinus surgery, evaluation was performed with the drivable endoscope and standard, rigid endoscopes (0°, 30° and 70°, as applicable). In visualizing all paranasal sinus anatomic landmarks, 55.6% better success rate was reported for the drivable endoscope vs the standard rigid endoscopes: 98.3% (178/181) vs 42.7% (76/178). For the usability of the drivable endoscope to enter the maxillary, frontal and sphenoid sinuses, surgeons rated scores of over 4 (on a 1–5 scale). A mean score of 4.3 and a mean score of 3.4, were accrued for its utility in irrigating the sinuses, and for its image quality, respectively. Postoperative evaluation of three patients suggests low pain and high tolerability scores with the drivable endoscope. As per these results, the drivable endoscope seems to an effective, easy to use and highly tolerable in sinonasal endoscopy.
