Context:
Marsupialization and decompression are treatments designed to reduce hydrostatic pressure which results in reducing the cystic size and increasing the bone density of the lesion.
Aims:
To compare the percentage of cystic size reduction and the percentage of change in radiographic density from marsupialisation and two types of decompression: tube drain and stent.
Settings And Design:
Retrospective analysis of panoramic films was conducted to evaluate cystic size and intralesional density.
Materials And Methods:
Data were analysed from 40 cases, including 31 cases of odontogenic cyst and 9 cases of cyst-like tumour, treated at Chulalongkorn University's Faculty of Dentistry from 2009 to 2019. The percentage of cystic size reduction and percentage of change in radiographic density were analysed before the procedure and three months after treatment. The density and size of the odontogenic cysts were determined using Image J software version 1.43.
Statistical Analysis:
Data were analysed using Kruskal-Wallis test.
Results:
The percentage of cystic size reductions when using marsupialisation, decompression with a tube drain and decompression with a stent were 31.49 ± 7.43, 35.42 ± 10.58 and 30.99 ± 7.16, respectively (P = 0.366). The percentage of change in radiographic density was 25.21 ± 7.04, 27.09 ± 7.96 and 24.94 ± 5.35, respectively (P = 0.661). There was no statistically significant difference in outcomes between the groups.
Conclusions:
Decompression with a tube drain yielded both the highest percentage of size reduction and the highest percentage of change in radiographic density in the cyst, although this better performance was not statistically significant. We recommend decompression with a tube drain, as it effectively maintains an open drainage pathway and prevents collapse of the cyst opening. This continuous release of hydrostatic pressure is beneficial in promoting gradual bone healing and regeneration.
