ABSTRACT
PURPOSE:
To investigate the utility of a hand-held digital otoscope for nasal endoscopy and as a pedagogy tool for residents and fellows in patients undergoing external dacryocystorhinostomy (DCR) surgery.METHODS:
A digital otoscope (MS450-NTE, Teslong Inc., USA) comprising a digital screen device and a connectible camera probe was used for performing nasal endoscopy. Inspection of nasal cavities was performed pre-, intra-, and post-operatively in sequential patients with nasolacrimal duct obstruction, who underwent DCR or lacrimal probing. Images (1920 × 1080 pixels) and videos (1280 × 720 pixels) were captured. The device was also used for training residents and fellows in performing nasal endoscopy, and to teach basic concepts.RESULTS:
The digital otoscope could be used for routine outpatient nasal examination and for performing minor procedures. 53.8% (n = 13) of ophthalmology trainees had never observed nasal endoscopy and 84.6% could not identify more than one major structure correctly prior to the current training. Post-training, all trainees could independently perform nasal endoscopy with the device and 76.9% identified all structures correctly.CONCLUSION:
A digital otoscope with a camera probe is a handy tool for nasal endoscopy and pedagogy. Low-cost gadgets such as this device can effectively be used for performing outpatient nasal endoscopy when expensive endoscopes are unavailable and in peripheral healthcare centers.Key words
