PURPOSE: to check the result of s/z ratio and types of voice in patients with diagnosis of organic-functional dysphonias (DOF) and functional dysphonias by incorrect use of voice (DFUIV), as well as the occurrence of the various pathologies within the DOF. METHODS: 70 subjects of both genders, between 5 and 65 years old, seen in a clinic-school, registered in a data bank from 1998 to 2006, with DOF and DFUIV, both classified in three sub-groups: cases in which the s/z ratio indicated hypercontraction, normality and lack of coaptation of the vocal folds during phonation. According to the occurrence, the types of voice were classified in: without alteration; noisy; compressed and/or presenting alteration of f0h; noisy and/or with alteration of f0h; and compressed. RESULTS: significant presence of DOF and DOF with vocal nodules; in DOF and DFUIV, significant presence of the normal s/z ratio with isolated times of /s/ and /z/ below the normal and noisy voice. CONCLUSIONS: the result of the s/z ratio was statistically significant in favor of the range of established normalcy, both in patients with a diagnosis of DOF, as well as with those with DFUIV, and that, in both groups of patients, the noisy voice was the most frequent. Within the DOF, the vocal nodules were significantly more frequent than the other pathologies.
