The voice on congenital isolated growth hormone deficiency (IGHD) is commonly refered high pitched voice . However, vocal and laryngeal data are rare within literature. In Itabaianinha County, Northeast Brazil, it had been described the most extend kindred with severe IGHD due to a GH-realising hormone receptor (GHRHR) gene mutation. The aim of this descriptive transversal study was to evaluate vocal and laryngeal affections in this group. 23 subjects with IGHD were studied, being 6 males and 17 females They were submitted to an otorhinolaryngological evaluation and strobovideolaryngoscopic exam. Besides, a speech evaluation like hearing perception analysis (GRBAS scale) and objective voice evaluation (maximum phonatory time, s/z ratio and acoustic analysis) were also used. The results were performed using qui-square, exact Fisher and unpaired t test (p<0,05). The main vocal complaints were vocal fatigue (36,36%), hoarsenesses (31,81%), sore throat (27,27%), neckache (27,27%), phonatory pain (22,72%) and aphonia (18,18%). No male presented any complaint. Based on findings, vocal abuse (72,72%), etilism (45,45%) and smoking (36,36%) were considered like nocive habits to normal voice. 72,7% of the subjects presented abnormal voice and 27,3% were the normal ones. Amongst the abnormal voice, the mild/moderate grade was prevalent, with the presence of roughness, breathiness and strain. The strobovideoalaryngoscopic exam in 21 subjects showed laryngopharyngeal reflux signs (66,66%), functional dysphonia (52,38%), vocal nodules (23,80%) and vocal cysts (9,52%). There was significant association between vocal complaints and grade of abnormal voice. There weren t association between abnormal voice and laryngeal diseases; nocive habits and abnormal voice; nocive habits and laryngeal diseases; laryngopharyngeal reflux signs and functional dysphonia; vocal complaint and laryngeal diseases. The maximum phonatory time was lower than 10s and s/z ratio was 1,19. In acoustic analysis, fundamental frequency was 221,06 Hz in females and 204,67 Hz in males. There wasn t statistical dependency between genders showing high pitch and dominance IGHD effect above gender. There wasn t statistical dependency between normal and abnormal voice in acoustic analysis neither. Conclusions: Voice presents high pitch in both genders and the most commonly abnormalities were roughness, breathiness and strain. The mild/moderate grade was prevalent. Laryngopharyngeal reflux signs and functional dysphonia were the most reached diagnostics using strobovideolaryngoscopic exam.
