Mucocoeles of the maxillary antrum extensive enough to cause local bone destruction appear to be extremely rare. Such a case is reported with the appropriate pathological and radiological findings. Perusal of the literature suggests that this condition, unlike mucocoeles arising in other sinuses, may closely mimic a carcinoma and all authors stress the necessity for Caldwell-Luc surgery to be certain of the diagnosis. Som and Shugar (1980) describe features visible on CT scanning which may help to differentiate between mucocoeles, pyocoeles and carcinomata. In spite of the relatively high incidence of cysts of the antrum, it is thought unlikely that mucocoeles in this location would arise from such a cyst; indeed it is likely that all mucocoeles arise from blockage of the outflow tract of the appropriate sinus. There is a high incidence of maxillary sinus mucocoele in Japan following Caldwell-Luc surgery (Hasegawa et al., 1979). Noyek and Zizmor (1976) suggest that compartmentalization of the antrum after operation may leave islands of mucosa without drainage; such a collection may give rise to a mucocoele.
上颌窦黏液囊肿广泛到足以引起局部骨质破坏的情况似乎极为罕见。本文报告了这样一例病例，并给出了相应的病理和放射学检查结果。查阅文献表明，与其他鼻窦发生的黏液囊肿不同，这种情况可能酷似癌肿，所有作者都强调必须进行柯-陆氏手术以明确诊断。索姆和舒加（1980年）描述了CT扫描可见的特征，这些特征可能有助于区分黏液囊肿、脓性囊肿和癌肿。尽管上颌窦囊肿的发病率相对较高，但一般认为该部位的黏液囊肿不太可能由这样的囊肿演变而来；实际上，所有黏液囊肿可能都是由于相应鼻窦流出道阻塞所致。在日本，柯-陆氏手术后上颌窦黏液囊肿的发病率较高（长谷川等人，1979年）。诺耶克和齐兹莫尔（1976年）认为，手术后上颌窦的分隔可能会使黏膜岛失去引流；这样的积液可能会引发黏液囊肿。
