Summary
Lateral manual compression testing offers a noninvasive method to assess vocal fold function before medialization laryngoplasty. This technique helps determine if surgical intervention is appropriate for effective glottic closure.
Area of Science:
- Otolaryngology
- Speech and Language Pathology
Background:
- Manual compression of laryngeal cartilages alters vocal fold characteristics.
- Laryngeal manual compression tests are used for preoperative assessment of medialization laryngoplasty.
Purpose of the Study:
- To objectively evaluate the lateral manual compression test using videostroboscopic, aerodynamic, and acoustic analysis.
- To assess the efficacy of this technique in patients undergoing medialization laryngoplasty.
Main Methods:
- Description of the lateral manual compression technique.
- Objective analysis using videostroboscopy, aerodynamic, and acoustic measures.
- Evaluation in a cohort of 10 patients.
Main Results:
- Preliminary findings in 4 patients suggest the test's utility.
- Effective glottic closure is indicated by conclusive test results.
- Comparison of advantages and disadvantages of the technique.
Conclusions:
- Lateral manual compression is a valuable, noninvasive adjunctive examination.
- The test aids in determining the need for medialization laryngoplasty.
- Further data collection will augment preliminary findings.
