Clinical and imaging research on decompression of mandibular odontogenic cyst
摘要
Abstract
Objective:To explore the differences between decompression and curettage on the treatment of mandibular odontogenic cyst. Methods:A total of 28 patients with mandibular odontogenic cyst over 3 teeth involvement in diameter (D≥6 cm) were selected and divided into the decompression group and the curettage group. The operation time and postoperative recovery were compared between the two groups. The preoperative and postoperative cone-beam CT (CBCT) data after 3, 6, 9 and 12 months were collected and reconstructed in three-dimension. The changes of bone volume fraction of the lesion and the newly regenerated bone were measured, while the relative position between cyst and the neural tube was also observed. Results:Mean operation time of the decompression group was significantly shorter than that of the curettage group (P＜ 0. 05). The class-A healing rate of the decompression group was significantly higher than that of the curettage group (P＜ 0. 05). The average cyst volume decreased more in the decompression group than in the curettage group in 3, 6, 9 and 12 months after the operation (P＜ 0. 05). The bone volume fraction of newly regenerated bone was significantly higher in the curettage group than the decompression group after 3 and 6 months (P＜ 0. 05). However, there was no significant difference after 9 months (P＞ 0. 05). It was significantly lower in the curettage group after 12 months (P＜ 0. 05). Ten cases with neurothlipsis preoperatively all had a recovery of neural tube in CT images after the decompression. Conclusion:Decompression can be a better choice for the treatment of mandibular odontogenic cyst.关键词
