Abstract
Abstract Background: Laryngeal disorders are often multifactorial in etiology. There are 4 main causes of voice disorders which are inflammatory, structural or neoplastic, neuromuscular and muscle tension imbalance. Visual inspection of the larynx is mandatory for diagnosis or exclusion of laryngeal disease. This is usually performed in the clinic. The method of laryngeal examinations varies from indirect mirror laryngoscopy to the use of rigid and flexible endoscopes. Laryngoscopy can be supplemented with stroboscopy, laryngography or digital acoustic voice analysis. Objective: To compare the accessibility and convenience of videolaryngoscopy using 70 - degree rigid sinuscope with flexible fiberoptic laryngoscopy in assessment of laryngeal lesions. Method: This study incorporated 67 patients with predominant laryngeal symptoms. All of them had been examined by videolaryngoscopy using 70 – degree rigid sinuscope and flexible laryngoscope. Six parameters had been evaluated and compared between the two procedures including: time of examination, successfulness, acceptance for the examination, no. of trials needed for optimum information, complications and discomfort level. Results: Successfulness was 95.5% in rigid videolaryngoscopy and 100% in flexible laryngoscopy. Patient's acceptance for examination revealed no significant differences between both procedures, however the average time spent during rigid videolaryngoscopy was significantly shorter than that spent by flexible laryngoscopy. No significant differences between both procedures regarding the no. of trials required for optimum examination but negligible level of discomfort was significantly less during rigid videolaryngoscopy. Failure of examination by rigid videolaryngoscopy was not significantly different than by flexible laryngoscopy. Conclusion: Using rigid videolaryngoscopy was significantly better regarding the average time spent by examination and the negligible level of discomfort felt by the patient.
