The purpose of this study is to assess the safety and effectiveness of the Peregrine endoscope in patients in the office setting in terms of access into and visualization of the paranasal sinus anatomy, image quality, patient tolerability and clinical utility. Up to 30 participants who have had prior endoscopic sinus surgery (ESS) and are scheduled for nasal endoscopy in the office as part of a routine post-operative office visit or due to recurrence of symptoms, will be evaluated with the Peregrine Endoscope as well as a standard endoscope. This study aims to: * compare visualization success rates of the paranasal sinus anatomy by Peregrine and by a standard endoscope used in the office setting. * examine device related adverse events. * assess the adequacy of the image quality of Peregrine for endoscopy procedures in the office. * evaluate patient tolerability and pain
