Upper: pictures before any interventions. Massive bilateral similar arytenoid edema (in respiratory position) causing dyspnea. Bottom: 30 months after the last surgery with erbium laser (in same respiratory position as preoperatively). No contact between anterior parts of the arytenoid area (in comparison to preoperatively) after treatment of both arytenoid areas with the erbium laser. Obvious difference in the edema of the anterior-posterior axis of the arytenoid area in comparison to preoperatively
