The sounds "ee" (/i:/) and "err" (/[see text]/) provide the best laryngeal visualization during indirect laryngoscopy. These vocalizations significantly improve diagnostic views compared to other tested sounds.

Area of Science:

Otolaryngology
Medical Imaging
Speech Science

Background:

Indirect laryngoscopy is a common diagnostic tool in otolaryngology.
Optimizing laryngeal visualization is crucial for accurate diagnosis.
The choice of vocalization can impact the quality of the laryngeal view.

Purpose of the Study:

To determine the optimal vocalization for achieving the best laryngeal view during indirect laryngoscopy.
To compare the efficacy of different vowel sounds in enhancing laryngeal visualization.

Main Methods:

A prospective study was conducted in an otolaryngology outpatient clinic.
Eighty-seven asymptomatic patients were included.
Views from indirect laryngoscopy using vocalizations /i:/ ('ee'), /ei/ ('ay'), /[see text]/ ('err'), /a:/ ('ah'), and /eă/ ('air') were graded.

Main Results:

The sounds /i:/ ('ee') and /[see text]/ ('err') yielded the highest number of adequate laryngeal views.
No significant difference was found between /i:/ and /[see text]/ (p = .740).
Significant differences were observed between /i:/ and /ei/ (p = .019), /i:/ and /a:/ (p = .00000), and /i:/ and /eă/ (p = .00013).

Conclusions:

The vocalizations /i:/ ('ee') and /[see text]/ ('err') are recommended for optimal laryngeal visualization during indirect laryngoscopy.
These sounds offer superior diagnostic clarity compared to /ei/, /a:/, and /eă/.
