Odontogenic cysts are usually treated by enucleation (cystectomy). Limited cysts (less than 5 cm) are usually managed by primary excision (total cystectomy), whereas larger ones (exceeding 5 cm) are often decompressed or marsupialized. Because it consists only of opening a much smaller surgical window, decompression is regarded as a more conservative method of treatment: this method associates the creation of an opening (window) into the cystic cavity with the suturing of a decompressing device (plastic tube or stent) at the periphery of the cyst. Apart from releasing intraluminal pressure in the pathological cavity, this procedure helps the lesion to progressively decrease in volume "with a gradual increase in bone apposition" and preserves pulp vitality and periodontal integrity of the adjacent teeth. We are reporting a case of a mandibular radicular cyst that was treated by decompression, followed by enucleation, bone reconstruction, and restoration with two osseointegrated dental implants. The cystic cavity progressively decreased in volume and increased in bone density.
牙源性囊肿通常采用摘除术（囊肿切除术）治疗。较小的囊肿（小于5厘米）通常通过一期切除（全囊肿切除术）处理，而较大的囊肿（超过5厘米）则常进行减压或袋形缝合术。由于减压仅需打开一个小得多的手术窗口，因此被视为一种更为保守的治疗方法：该方法是在囊肿腔内开一个口（窗口），并在囊肿周边缝合减压装置（塑料管或支架）。除了释放病变腔内的腔内压力外，此操作有助于病变体积逐渐减小，“同时骨附着逐渐增加”，并保留相邻牙齿的牙髓活力和牙周完整性。我们报告一例下颌根端囊肿，先采用减压治疗，随后进行摘除、骨重建，并植入两颗骨结合式牙种植体进行修复。囊肿腔体积逐渐减小，骨密度增加。
