北京读者李先生:我今年31岁,前两个月发现下嘴唇里面起了个泡,起初像绿豆大小,后来长到黄豆大小,反复破了又长,请问这是怎么回事?连线医生——北京大学口腔医院颌面外科副主任医师王洋根据这位读者描述,应该是下唇黏液囊肿。除了腮腺、颌下腺、舌下腺这3对大的唾液腺以外,还有一些小的唾液腺分布在腭部、嘴唇内侧以及舌部。这些腺体都能产生唾液,并由导管负责把唾液分泌到口腔里,如果导管损伤或堵塞了,唾液就可能外渗,从而在局部形成黏液囊肿。下唇是其好发部位,常表现为黄豆大小、边缘清晰的透明小泡,破溃后可流出乳白色黏稠液体,很容易复发,反复破溃后局部黏膜可形成瘢痕,表现为白色硬结。下唇黏液囊肿可用手术切除,手术较为简单,需要在局
