Summary
Stroboscopic evaluation of the vocal fold mucosal wave aids in distinguishing true vocal fold (TVF) cysts from polyps. Providing clinical details to pathologists is crucial for accurate histopathology, refining diagnoses.
Area of Science:
- Otolaryngology
- Laryngology
- Vocal Fold Pathology
Background:
- Differentiating benign vocal fold lesions like cysts, polyps, and nodules is crucial for surgical decision-making.
- Stroboscopic examination offers a non-invasive method to assess vocal fold vibratory characteristics.
Purpose of the Study:
- To evaluate the efficacy of stroboscopic parameters, particularly mucosal wave, in differentiating true vocal fold (TVF) cysts and polyps.
- To assess the impact of clinical information on histopathologic diagnosis accuracy.
Main Methods:
- Retrospective analysis of 32 patients over 31 months.
- Stroboscopic examinations assessed symmetry, amplitude, periodicity, mucosal wave, and closure.
- Preoperative diagnoses were confirmed by operative findings and histology.
Main Results:
- Absence or diminished mucosal wave was observed in 100% of TVF cysts.
- Present or increased mucosal wave was noted in 80% of TVF polyps (P < .05).
- Histopathologic diagnoses were revised in 31% of cases after clinicians provided relevant clinical information.
Conclusions:
- Stroboscopic evaluation of the mucosal wave is a valuable tool for preoperative differentiation between TVF cysts and polyps.
- Sharing clinical information with pathologists is essential for accurate and reliable histopathologic diagnoses.
