OBJECTIVE: The objective of the current study was to evaluate the outcome of decompression prior to enucleative protocol for the large cystic lesions treatment and to correlate the depletion rate of keratocyst odontogenic tumor, dentigerous cyst and ameloblastoma at specific times. (Preoperative and at six-month post-operative). There are relatively fewer studies and also a lack of literature on the topic at hand in Pakistan. This research lets us observe the shape of bones after decompression and the performance of surgical enucleation with less risk on vital anatomic elements.
METHODOLOGY: A comparative cross sectional study was conducted at Advance Dental Care Center LUMHS Hyderabad from the year 2016 to 2017. The study consists of 40 patients (out of which 23 were male and 17 were females). They were selected, using non-probability sampling technique, incorporated 40 subjects of mean age 31.22±8.78 years having massive mandibular lesions (>3cm). The use of decompression was to release the intraluminal pressure and to decrease the volume of lesion. Three-dimensional computed tomography scan was exercised to the patients at the stage of diagnosis and at six-months after decompression. Volumetric examination was executed using a software device for three-dimensional quantification of volumes.
The qualitative variable like gender and quantitative variables such as age and reduction rate were also calculated.
Results: There were notable variations in the rates of reduction between initial and 6-month volume of the lesion. No compelling differences were found in the statistical analysis between the groups about age, gender and histological type of lesion. (p>0.05).
CONCLUSION: Decompression prior to enucleation protocol for the large cystic lesions treatment accompanied by enucleation turns up to be a beneficial measure for managing massive mandibular cystic lesions and there is a correlation of the depletion rate of keratocystic odontogenic tumor, dentigerous cyst and ameloblastoma preoperative and at six-month post- operative.
