An antral pseudocyst on the maxillary sinus has previously been a contraindication for sinus augmentation. The authors report the case of a patient with an antral pseudocyst (16.7 mm × 27.6 mm) in his left sinus, who was referred for dental implant treatment. The surgical plan was to perform the sinus augmentation after removing the cyst whilest simultaneously placing implants. During the operation the cyst could not be found in the left sinus. The sinus augmentation was carried out successfully without sinus membrane perforation and the implants were placed according to plan. Three mouths later, the cyst was still present and good osseointegration of the implants was achieved. After the implants had been in place for a year, a CT scan showed that the cyst had decreased in size. The authors conclude that it is may not be necessary to remove a sinus cyst before sinus augmentation or during the sinus augmentation operation if the patient does not have any symptoms and the cyst is not large. In cases with large lesions or an unclear diagnosis, further evaluation is needed before surgical intervention.
上颌窦内的窦腔假性囊肿先前被认为是鼻窦增高术的禁忌症。作者报告了一例左侧窦腔有窦腔假性囊肿（16.7mm×27.6mm）的患者，该患者因需要进行牙种植治疗而被转诊。手术计划是在切除囊肿的同时进行鼻窦增高术，并同时植入种植体。在手术过程中，左侧窦腔未发现囊肿。鼻窦增高术成功进行，没有出现鼻窦膜穿孔，并且按照计划植入了种植体。三个月后，囊肿仍然存在，种植体的骨整合良好。种植体植入一年后，CT 扫描显示囊肿体积减小。作者得出结论，如果患者没有任何症状且囊肿不大，则在鼻窦增高术前或术中不一定需要切除鼻窦囊肿。对于大病灶或诊断不明确的病例，在进行手术干预之前需要进一步评估。
