Abstract
Aim: to determine the incidence and clinic-demographic profile of patients undergoing microlaryngeal surgery.
 Materials and Methods: this is a prospective study of 100 patients attending an outpatient department with laryngeal lesions evaluated irrespective of their age, sex, and occupation. Biopsy-confirmed malignant cases were excluded.
 Result: of the 100 patients, 84 of them exhibited benign lesions and rest 16 patients showed malignant pathology. Most commonly seen benign vocal lesion is vocal nodule (37.0%) followed by vocal polyp (28.0%). Along with hoarseness of voice, other symptoms reported were cough and throat pain, Dysphagia and fever. Improvement in symptoms was seen after the treatment.
 Conclusion: Microlaryngeal surgery is a good therapeutic tool in both benign and malignant lesions. The differentiation of benign from malignant lesions is vital. Microlaryngoscopic examination has proved to be the best modality for visualizing these lesions and arriving at a clinical diagnosis

Summary
Larynx is a vital body organ that functions as an airway and the organ of phonation. The benign laryngeal lesions occur in a ratio of 2:3 to the malignant lesions. Various studies opined that true benign neoplastic lesions are uncommon and occur in a ratio of 1:6 to the non-neoplastic lesions.[1] Some of these tumors may even undergo malignant changes like papilloma (4%), granular cell tumor (2%).[2,3]. Microlaryngeal surgery along with speech therapy is one of the most powerful techniques to address laryngeal and voice disorders in all age groups. Microlaryngeal surgery (MLS) is minimally invasive procedure to visualise magnified view of larynx through videolaryngoscope or operating microscope for diagnostic and therapeutic purpose using microlaryngeal instruments.[4]
