CONCLUSION: Satisfied results have been received for treatment of benign laryngeal changes by laser under fibrotic laryngoscope and it was better than median laryngotomy and excision under direct and indirect laryngoscope. For those who are difficult under indirect laryngoscope, fibrotic laryngoscope is especially useful.
