耳郭血肿或血浆肿,多为外伤所致。若不治疗或治疗不当可造成外耳畸形。通过动物实验证实:耳郭击伤后,血液积聚在已剥离的软骨膜下,可导致机化、纤维化和新软骨形成。在处理上为防止畸形,曾有多种方法,如切开引流,抽吸后压迫或抽吸后以石膏模型压迫包扎,或从耳后切口,切除部分软骨,然后以棉枕或毡枕缝于外侧面作支撑。作者将Stuteville(1969)采用过的火棉胶与棉花作成耳模型的方法加以改进,即
Ear Guo hematoma or plasma swollen, mostly due to trauma. If not treated or improper treatment can cause the outer ear deformity. Animal experiments confirmed: After the auricle injury, blood accumulation in the stripped perichondrium, can lead to mechanization, fibrosis and new cartilage formation. In the treatment to prevent deformity, there have been a variety of methods, such as incision and drainage, aspiration or aspiration after suction gypsum model pressure dressing, or incision from the ear, remove part of the cartilage, and then cotton pillow or felt pillow seam On the outside for support. The authors improved the method of making ear models by using cotton collodants and cottons by Stuteville (1969), namely
