OBJECTIVE: To analyze normal and pathological glottal image quantitatively with computed image technique, and try to calculate the absolute value of the laryngeal parameter.
METHOD: The glottal image parameters of 60 normal adults, 60 cases of vocal polyps and 40 unilateral vocal fold paralysis(UVFP) patients were measured and analyzed, including the relative and absolute maximum or minimum glottal area, that is Amax(r), Amin(r), Amax(a) and Amin(a) respectively.
RESULT: Amin(r) of females was larger than that of males; and both were larger than zero. He and she were equal in Amin(a) and Amax(r), while Amax(a) of males was larger than that of females. Compared with normal adults, Amin(r) of the patients with vocal polyp increased, and Amax(r) of UVFP patients diminished, while their Amin(r) increased.
CONCLUSION: Laryngeal image could be analyzed quantitatively with computer assisted fibrolaryngoscopy. Normal adults have incomplete glottal closure to certain degree, and the level is different between sexes. The patients with vocal polyp and UVFP have relevant pathological glottal image.
