Objective:
The aim of this study was to evaluate the effectiveness of decompression as the initial treatment for odontogenic cysts.
Study Design:
Pre- and postdecompression panoramic radiographs of 57 patients treated for 73 odontogenic cysts were reviewed for reduction parameters. Findings were evaluated against time of decompression and clinical and histopathologic data.
Results:
Decompression reduced lesion area by a mean of 79.3%. The reaction was good in 60% of cysts, moderate in 29%, and poor in 11%. Mean decompression time was 9.2 ± 5.2 months; it was 7.6 months in patients ≤18 years old and 10.2 months in older patients (P < .0001). Mean rate of reduction was 0.14 in cysts <10 cm(2) and 0.10 in cysts >20 cm(2) (P = .0884); by age, values were 0.14 in patients ≤18 years old and 0.09 in older patients (P < .05).
Conclusions:
Decompression is effective in reducing odontogenic cysts. A shorter decompression period is needed for young patients. For aggressive lesions, secondary definitive surgery is recommended.
