[Diagnostic value of stroboscopy in early glottic carcinoma].
Stroboscopic evaluation was conducted on 34 cases with glottic T1 carcinomas, and the relationship was studied between the area, thickness and volume of the lesion and the amplitude as well as mucosal wave of vibration. In all cases the mucosal wave of the lesion (WAVL) was abolished. The amplitude of the lesion (AMPL) was decreased in 17 and abolished in another 17 cases. There were significant relationship between the area of the lesion and the mucosal wave of the entire vocal fold (WAVE), the thickness of the lesion and AMPL, and the volume of the lesion and WAVE, AMPL, and the amplitude of the entire vocal fold (AMPE). The present paper suggested that if WAVL is reserved, the lesion is not invasive carcinoma, nor is it if any one of AMPE, AMPL, WAVE or WAVL is normal (except for lesions confined to the cartigenous vocal fold).
