Abstract：
Objectives: A mucous retention cyst is a common, asymptomatic lesion that may cause complications during or after the sinus lift procedure. The goal of this study is to assess the effectiveness of the Croco Eye Technique (CET), which allows simultaneous excision of the cyst and sinus floor elevation. Methods: The technique was thoroughly described in two versions, and the group of 33 patients was analyzed. Patients who qualified for this procedure had insufficient alveolar ridge height, and their CBCT showed radiological images typical for retention cysts. Analyzed parameters included the version of CET, demographic data, anatomical parameters, intraoperative complications, recurrence of the cyst, success rate of the sinus lift and implants, and the follow-up period. Results: Out of the 33 cases, 9 were of the primary version (27.27%) and 24 of the final version (72.73%). The average height of a retention cyst was 24.05 mm, with the average alveolar ridge height of 1.86 mm. In three cases (9.09%), implants were placed immediately. The prevalence of uncontrolled Schneiderian membrane perforation was reduced from 55.56% to 4.17% between the primary and final versions. The cyst\'s recurrence rate was 3.13%. The implant survival rate was 100%. The mean follow-up period was 48.625 months (max 110 months). Conclusions: The Croco Eye Technique, despite the perforation of the Schneiderian membrane, enables successful sinus lift and implantation with a success rate of 100%. Excision of the retention cyst, which is the cause of perforation, allows for limiting the risk of the cyst\'s recurrence.
摘要：
目的：黏液潴留囊肿是常见的，无症状性病变，可能在鼻窦提升术期间或之后引起并发症。这项研究的目的是评估Croco眼科技术（CET）的有效性，可以同时切除囊肿和窦底抬高。方法：该技术在两个版本中进行了全面描述，并对该组33例患者进行分析。符合此手术资格的患者牙槽脊高度不足，他们的CBCT显示了典型的保留囊肿的放射学图像。分析的参数包括CET的版本，人口统计数据，解剖参数,术中并发症,囊肿复发,鼻窦提升和植入物的成功率，以及后续期。结果:33例患者中,9个是主要版本（27.27％），24个是最终版本（72.73％）。保留囊肿的平均高度为24.05mm，平均牙槽脊高度为1.86mm。在三个案例中（9.09%），立即放置植入物。在主要版本和最终版本之间，不受控制的施耐德膜穿孔的患病率从55.56％降低到4.17％。囊肿复发率为3.13%。种植体成活率为100%。平均随访时间为48.625个月（最大110个月）。结论：Croco眼科技术，尽管Schneiderian膜穿孔,能够成功地抬起和植入鼻窦，成功率为100％。保留囊肿切除术，这是穿孔的原因，允许限制囊肿复发的风险。
