Portable Endoscopic Camera System Using Modified Action Camera for Endoscopic Sinunasal Examination
University of Arkansas
Summary
This study is designed to compare two methods for performing a nasal endoscopic examination used in the evaluation of excessive watering or tearing of the eyes. The purpose of the study is to determine whether a new, smaller, modified camera system can produce images of the inside of the nose that are as clear and useful as those produced by the standard endoscopic camera system currently used in clinics. The study seeks to answer the question of whether a compact, easy-to-store camera system can provide similar diagnostic image quality to the traditional, larger tower-based system. The clinical steps of the nasal examination remain the same; the only difference is the type of camera system used to capture the images.
Description
This study evaluates two imaging systems used during routine nasal endoscopy performed for assessment of epiphora and related nasolacrimal or sinonasal concerns. The protocol involves conducting a standard nasal endoscopic examination with the conventional full-size tower-mounted camera system typically utilized in ophthalmology and otolaryngology outpatient settings, followed by a second examination using a modified compact camera system. Both examinations use the same endoscope and follow identical clinical steps. The modified camera system attaches at the usual hand-position point on the e…

Inclusion Criteria: * Adult patients (18 years and older) presenting with tearing suggestive of nasolacrimal drainage obstruction * Adult patients presenting with sinunasal disease with clinical findings on endonasal examination. * Adult patients who require a clinically ordered nasal endoscopic exam. Exclusion Criteria: * Children (Under the age of 18) * Patients with over secretory tearing.
Interventions
- DeviceModified Portable Endoscopic Camera
The Sony Action Camera was modified to allow direct coupling with a standard rigid nasal endoscope: 1. The native 180° wide-angle lens was replaced with a narrow-field 31° lens, enabling full-frame capture of the endoscopic image without peripheral distortion. 2. The camera housing was adapted by attaching a ¾-inch water pipe end connector, serving as a secure and stable mount for the endoscope eyepiece. The modified system captures both video and still images.
