Comparison Of Fenestration, Suction Drainage And Curettage For Odontogenic Jaws Cystic Lesion

Objective This study is recorded the image changes by periapical and panoramic radiographs, spiralCT, measured lesions’ changes and statistically analyzed before and after of odontogenic jaw cystic lesions’treatment. The difference of curative effect is preliminarily studied and contrasted between the differentsizes of the cysts taken different treatment methods. They are provided reliable reference for the clinicaltreatment of odontogenic jaw cystic lesions, and guided choice of treatments for different lesions.Methods They are chosen which are30cases of patients with odontogenic jaw cystic lesions, accordingto the size of the lesions which were divided into Group Ⅰ and Ⅱ. According to clinical situations andpatients’ will, group Ⅰ (large jaw cystic lesions, maximum diameter≥3.5cm) is divided into group A andB, respectively with simple fenestration decompression and fenestration decompression combined withsuction drainage. The area and clinical volume of intraoperative ago and postoperative the2,4,6months arerecorded, and all measured data is transferred to the percentage to reduce of area and volume. Group Ⅱ(small jaw cystic lesions, the maximum diameter <3.5cm) is divided into group A and B too, respectivelywith simple fenestration decompression and disposable curettage. The area of postoperative the3,6monthsare recorded, and all measured data is transferred to the effective rate. Resultant data were statisticallyanalyzed using SPSS11.0. Results (1) The percentage to reduce of cavity’s area and volume in GroupⅠB is respectively higher than group ⅠA at postoperative the2,4,6months, and the difference wasstatistically significant (P <0.05).(2) The effective rate to reduce in group ⅡB is higher than group ⅡA,and the difference was statistically significant (P <0.05). Conclusion (1) For the large odontogenicjaw cystic lesions, the curative effect in group fenestration decompression combined with suction drainageis more surpassing than group simple fenestration decompression.(2) For the small odontogenic jawcystic lesions, the curative effect in group disposable curettage is more surpassing than group simplefenestration decompression.
