Thirty-one patients with endochondral pseudocysts of the auricle were seen over a four-year period in the Department of Surgery at the University of Hong Kong. The lesions chiefly affected Chinese males (90.3%); 80.6% involved the scaphoid fossa on the anterior surface of the pinna. They were usually asymptomatic and static in size. Excision of the anterior wall, followed by contour pressure dressing, gave cosmetically satisfactory results in 90% of the patients, and there were no recurrences. Pathologic studies revealed the absence of an epithelial lining as well as multiple cystic spaces that contained abundant glycosaminoglycans (acid mucopolysaccharides). We postulate that the overproduction of glycosaminoglycans engendered by repeated minor trauma to the cartilage was the primary cause of the pseudocysts.
在香港大学外科，四年期间共诊治了31例耳廓软骨内假囊肿患者。这些病变主要累及中国男性（90.3%）；80.6%累及耳廓前表面的舟状窝。它们通常无症状，大小稳定。切除前壁，随后进行塑形加压包扎，90%的患者获得了满意的美容效果，且无复发。病理研究显示无上皮内衬以及多个含有丰富糖胺聚糖（酸性粘多糖）的囊性间隙。我们推测，软骨反复轻微创伤导致糖胺聚糖过度产生是假囊肿的主要原因。
