Treatment of Keratocystic Odontogenic Tumours: A Prospective Study of 30 Cases
- 201 Downloads
This prospective study aimed at presenting different treatment modalities and its association with the recurrence rate of KCOT.
Material and Method
The study was conducted on 30 patients diagnosed with KCOT between March 2009 and 2012. The patients were followed up for a period of at least 1 year. The clinical, radiographic and demographic data were recorded and four different treatment modalities were followed to assess the recurrence of the tumour.
In the study, KCOT showed male predominance with a male: female ratio of 23:7. Of the total cases, 26 (86.67 %) patients had parakeratinised KCOT and the rest 4 (13.3 %) patients had orthokeratnised KCOT. Nine (30 %) patients were reported with recurrence of the tumour within 1–2 years of surgery—all these patients had parakeratinised cyst. Recurrence was observed in four (50 %) out of eight cases of marsupialisation and four (44.44 %) out of nine cases of treatment using the enucleation process. No recurrence was seen in patients treated with resection; however only one out of three patients treated with enucleation, followed by fixation with Carnoy’s solution showed signs of recurrence. The histopathological examination determined the aggressive nature of KCOT and its association with the recurrence rate as well. The findings of our study indicate that more aggressive treatment can aid in reducing the chances of recurrence.
