Abstract
UNLABELLED: PUPPOSE: To evaluate the effect of decompression for large mandibular odontogenic keratocystic tumours in adolescents. METHODS: Fifteen cases of large odontogenic keratocystic tumours in mandible underwent decompression from Feb.2005 to Feb.2011, the average age of the patients was 19.3 years. Patients were follow-up by X-ray every 2-3 months, and every 6-12 months by CT. Subsequent curettage was given when the remaining tumours were less than 2cm in diameter. RESULTS: The decompression period lasted from 12 to 18 months, with an average time of 13.6 months. After decompression, bone regeneration was noticed on radiographs, the average decrement percentage of the tumour size was 41.5% at 6-month, 61.5% at 12-month and 81.8% at 18-month after operation. All patients were followed up for 1-5 years after secondary surgical curettage, no recurrence was observed. CONCLUSION: Decompression is a preferred treatment for large mandibular odontogenic keratocystic tumours in adolescents.
