Abstract

Purpose

To compare high-speed videolaryngoscopy (HSV) findings, like open quotient (OQ), vocal fold vibratory onset delay (VFVOD), amplitude symmetry index (ASI) and phase symmetry index (PSI), after 6 months of cordectomy with that after 1 year, and to compare later with the control group.

Methods

Retrospective analysis of HSV recordings of 33 patients of early glottic carcinoma after cordectomy was performed after 6 months and 1 year of cordectomy with the help of videokymogram and digital kymogram. The control group of ten individuals was selected from patients who came to hospital with complaints other than larynx. The comparison was done for different types of cordectomy separately.

Results

The mean of OQ, VFVOD, ASI and PSI was found to be significantly higher after 6-month follow-up than after 1-year follow-up, the later was in turn found to be significantly higher than that of the control group, for type II and III cordectomy. The mean of OQ, VFVOD, ASI and PSI for other types of cordectomy also showed similar results, but the significance was not calculated due to less sample size.

Conclusion

There was significant improvement in OQ, VFVOD, PSI and ASI following CO2 LASER cordectomy after 1 year of follow-up, making it a good management option for early glottic carcinoma. The ability of the HSV to measure variations in the vocal cord vibration, following cordectomy, was well established by this study.
