Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Medical Devices

Background:

  • Endoscopic endonasal surgery requires specialized instruments for tissue manipulation.
  • Traditional retractors can be cumbersome in the restricted nasal passages.

Purpose of the Study:

  • To introduce a novel, practical alternative for gentle tissue retraction in endoscopic endonasal procedures.
  • To evaluate the utility of a common household item as a surgical tool.

Main Methods:

  • A cotton swab (Q-tip) was utilized for tissue retraction in 100 endoscopic endonasal procedures.
  • The Q-tip's design allows it to share space with endoscopes and other instruments.
  • Surgeons actively controlled the Q-tip for precise retraction force and direction.

Published on: May 23, 2021

Main Results:

  • The Q-tip facilitated gentle retraction without causing injury to critical neurovascular structures.
  • Its shape and flexibility allowed for maneuverability within the nasal cavity.
  • The tool proved effective in reaching deep surgical areas.

Conclusions:

  • The Q-tip cotton swab is a suitable and cost-effective alternative for retraction in endoscopic endonasal surgery.
  • Its thin, long, and soft characteristics meet the requirements for safe retraction in confined surgical spaces.
