Simple decompression of odontogenic cyst

Abstract

Marsupialization or decompression can be performed, especially to decrease complications when the cyst size is too large or there is risk of injury to the adjacent structures. In this study, we attempt to evaluate the change in the cystic lesion after decompression with a silicone tube through dental panoramic radiographs at regular time intervals. All 7 patients, who had been diagnosed and treated for an odontogenic cyst in the jaws with decompression from January 2007 to January 2014, were included in the study. Differences between pre-operative panoramic radiographs and post-operative panoramic radiographs were analyzed for evaluating the size of each cyst, and the calculation of reduction rate was used. The average period was 426.6 days between decompression and secondary enucleation. The average reduction rate of the cyst was 67.68%. During the treatment, the average reduction rate per day was 0.178 %. Histologic examination after final enucleation showed no signs of cystic remnants. No recurrence occurred during the 2-year follow-up period. Decompression with a silicone tube causes less bone defects since it is necessary to remove only the upper bone as wide as the tube diameter. It can be considered as an effective treatment method because it causes no significant changes after healing and it can be applied easily.
