In Brazil, the teaching profession is considered at high risk for the presence of the voice disorder. Among the different pathological factors responsible for this, laryngopharyngeal reflux (LPR) has been registered teachers with voice disorders. Objective: To analyze the relationship between the presence of videolaryngoscopic signs suggestive of laryngopharyngeal reflux and voice disorders in teachers looking for care. Method: research, transversal, convenience sample that had as inclusion criteria, be 18 years old, seeking care in a sector of Otorhinolaryngology of a public hospital in São Paulo, in the period from August 2013 to May 2014 (total of 10 months), being a teacher female (once women seek a greater number said Sector) with voice disorders (VD) or LPR. The exclusion criteria were: smoking, and provide respiratory changes. In this sense, the initial sample of 158 teachers and after exclusion of subjects, 121 teachers were included in the final sample. All subjects underwent the following instruments: Vocal Production Condition - Teacher (VPC-T), including the Screening Index for Voice Disorder (SIVD); and Voice Handicap Index (VHI). Sample collection was made speech for assessing voice quality, made by speech therapists through the GRBASI scale. All participants underwent otorhinolaryngologic medical evaluation. Descriptive analysis and analysis of mean differences was performed. The relationship between the independent variables to the variable LPR outcome we used the chi-square or Fisher's exact test. Results: A total of 121 teachers, mean age of 43 years and a mean of 7.8 hours / class per day. Only 24.0% (n = 29) of the teachers no lesions on the vocal folds and 42.1% (n = 51) had videolaryngoscopic signs suggestive of LPR. In total, it was found that the symptom of hoarseness SIVD got higher occurrence record. In the group with presence of LPR signals, the most common symptoms were: dry throat, hoarseness and throat clearing; VHI and mean was 17.9. In the group of teachers who did not show signs suggestive of LPR symptoms were hoarseness, failure in voice and vocal fatigue; VHI and mean was 16.4. There was no association between LPR signals and voice disorder. In the multiple binary logistic regression analysis, the independent factors for the LPR were age, presence of vocal slot and VHI score (13-20). Conclusion: The presence of videolaryngoscopic signs suggestive of LPR registered in almost half of the studied teachers was not associated with presence of VD. The relationship was recorded in teachers: older; in presenting the presence of vocal slot; and those who were self-reference vocal handicap VHI score
