慢性上颌骨肺不张（CMA）被认为是由继发于窦口鼻道复合体阻塞的上颌窦负压引起的。一位49岁的女性病人，第一次来我院主诉右鼻充血、溢鼻及脸颊疼痛。计算机断层扫描（CT）意外发现左上颌窦向内弯曲，这是CMA或沉默窦综合征的典型体征，尽管上颌窦口是有力的。我们没有考虑对CMA进行任何干预，因为她没有相关的症状。在6个月的随访中，临床或CT均未发现进展。我们病人的CMA的发病机制不能用公认的理论来解释。CT证实左侧上颌骨明显肥大，因此慢性鼻窦炎骨炎可能是开放性上颌窦CMA的潜在原因。
Chronic maxillary atelectasis (CMA) is assumed to be caused by negative pressure in the maxillary sinus secondary to the obstruction of the ostiomeatal complex. A 49-year-old female patient first presented to our hospital complaining of right nasal congestion, rhinorrhoea and cheek pain. Computed tomography (CT) accidentally revealed the inward bowing of the left maxillary sinus, which is a typical sign of CMA or silent sinus syndrome despite the maxillary ostium being potent. We did not consider any intervention for CMA because she had no symptoms related to it. No progression was noted clinically or on CT at the 6-month follow-up. The pathogenesis of CMA in our patient was not explainable by the commonly accepted theory. Apparent hypertrophy of the left maxillary bone was confirmed on CT, thus osteitis with chronic rhinosinusitis might be the potential cause of CMA in the open maxillary sinus.
