The document discusses congenital lesions of the larynx that can occur during development. It describes how the larynx forms from the pharyngeal region between 4-10 weeks of gestation. Common congenital lesions include laryngomalacia (60%), vocal cord paralysis (20%), and subglottic stenosis (15%). Supraglottic lesions include laryngomalacia, laryngocoele, and cysts. Glottic lesions comprise vocal cord palsy, webs, and stenosis. Subglottic abnormalities are stenosis, hemangioma, and webs. Clinical features, diagnosis, and management are outlined for each condition. Flexible laryngoscopy is important for diagnosis while treatment
