Summary
Laryngologists show varied preferences for laryngoscopes in glottic, subglottic, and hypopharyngeal surgery. Surgeons suggested modifications like altering shape and adding ports for improved laryngoscopy innovation.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Medical Device Design
Background:
- Direct laryngoscopy has evolved significantly since the mid-1800s.
- Numerous variations of the direct laryngoscope exist.
- Surgeon practice patterns and preferences for specific laryngoscopes remain under-investigated.
Purpose of the Study:
- To evaluate surgeon preferences for direct laryngoscopy and suspension apparatus in glottic, subglottic, and hypopharyngeal surgery.
- To understand the rationale behind these preferences.
- To gather recommendations for future laryngoscope modifications and innovations.
Main Methods:
- An anonymous electronic survey was distributed to laryngologists worldwide.
- Respondents reported their preferred laryngoscopes, reasons for choice, and suggestions for innovation.
- Data were collected and aggregated for analysis.
Main Results:
- 128 laryngologists responded; 84% had completed a laryngology fellowship.
- Preferences varied by surgical site: Dedo and Universal Modular Glottiscope (UMG) for glottic; Weerda for hypopharyngeal; Dedo for subglottic.
- "Size of working space" and "favorable design for difficult exposures" were key rationale.
- Suggested modifications included altering laryngoscope shape and adding a port.
Conclusions:
- Surveys revealed variable agreement among laryngologists regarding instrument selection.
- Respondents proposed modifications indicating a need for continued innovation in laryngoscope design.
- Further research is warranted to explore these proposed changes and their impact.
