Disorder Voice is a voice which is not capable of fulfilling its linguistic and paralinguistic functions. Among professional voice users teachers form the largest group seeking medical help for their voice problems. We aim to find the prevalence of voice disorder in teachers of Eastern Nepal and determine risk factors associated with voice disorder.307 teachers of various institutions of Morang and Sunsari district were selected after proportionate stratified sampling method from April 2012 to March 2013. They were filled with standard questionnaire and underwent basic clinical and otorhinolarynogological examinations. Flexible nasal endoscopy and 700 direct Endoscopy performed in the department. Out of 307 teachers, 190 (61.89%) had voice disorder out of which primary school teachers have more prevalence (67.4%) as compared to non-primary teachers (p<0.012) . Majority had Laryngopharyngeal Reflux (25.79%), Acute Laryngitis (23.16%), Vocal Cord Nodule (21.05%), Vocal Cord Polyp (17.37%), Vocal Cord Cyst (5.26%), Reinkes Oedema (3.68%), Leukoplakia (2.11%) and Functional Dysphonia (1.58%). Teachers with more than 20 years was weak statically significant (p=0.051) with voice disorder. Tobacco (p= 0.408) and Alcohol (p=0.96) was not statistical significant with voice disorder whereas smoking (p=0.039) and chalk user (p<0.001) was associated with voice disorder.
