Larynx is an important organ of the body. The primary function of the larynx is to provide protection to the lower airway. It secondarily evolved to serve as a vocal generator of sound. The larynx produces sound which is the major medium of communication. Voice helps in expressing emotions even without the help of language. It expresses the mood and attitude. It is the tone of voice which gives meaning, while in verbal use, the quality of voice is very significant specially for professional voice users like singers. The spectrum of voice disorders is very wide and its impact on different individuals also varies. Benign lesions of the larynx include neoplastic and nonneoplastic lesions. They are broadly classified together because clinically they behave similarly. Any lesion affecting the larynx will cause a range of voice disorder. Voice disorders caused by benign lesions are correctable by surgery and voice rest and voice therapy in few cases. In the present study, 70 cases of benign lesions of the larynx were studied. All lesions presented with some kind of voice disorder. 90% of the cases presented with hoarseness, while another 42% had vocal fatigue. 42% had reduced vocal range and 4.4% had aphonia. Amongst the causative factors of vocal nodule, vocal abuse was a common constant cause. 57% of the affected patients were smokers while both the cases of vocal granuloma had a previous history of endotracheal intubation. The sex distribution of different lesions were different. Maximum patients presented were in the third decade (26.8). This was followed closely by patients in the second, fourth and fifth decade. Video laryngoscopy was the most specific modality of investigation. Computed Tomography, Magnetic Resonance Imaging and Electroglottogram were not considered necessary. Microlaryngeal excision was done for majority of the cases followed by voice rest and anti reflux medicines in some cases. Results were very good thereby saving substantial number of man days.
