Figure 3. The schematic representations of the treatment options for pharyngolaryngeal hemangioma. (A) Sagittal image and (B) Coronal image. The mucosa at the margin of the hemangioma in the pre-epiglottic space, laryngeal surface of the epiglottis, pharyngoepiglottic fold, aryepiglottic fold, and arytenoid was incised (yellow dotted line). Next, the margin and hemangioma abutting epiglottis and arytenoid was dissected using the CO2 laser (yellow solid line). The hemangioma in the pharyngoepiglottic fold and aryepiglottic fold was excised using an ultrasonic scalpel (black solid line). The hemangioma in the ventricle, false vocal fold, and paraglottic space was treated by KTP laser photocoagulation until it was no longer visible under the microscope (green solid line). A – arytenoid; E – epiglottis; F – false vocal fold; T – true vocal fold; V – ventricle.
