Assesment of recurrence of odontogenic keratocysts treated with different surgical modalities -nine years follow up of disease

ABSTRACT

The purpose of this study was to determine the Recurrence rate of odontogenic keratocysts [OKC] and association of recurrence with various surgical modalities. It was cohort analytical study. Eighty-two odontogenic keratocysts cases treated at Oral and Max illofac ial department Armed Forces Institute of Dentistry, Rawalpindi farmed the study subject, and were followed for a period of 9 years from 2004 to 2013. Recurrence ofOKCs were evaluated from 1-9 years after surgical treatment by clinical and ra-diographic means and correlated with various treatment modalities. The most frequent site affected by OKCs was the posterior mandible including body, angle and ramus. Patients were followed for recurrence. 16 patients were lost to follow up and this journal was 14 cases of recurrence out of 66 were treated with varying modalities [21.2%]. Patients treated conservatively with marsupialization or enucleation alone demonstrated higher recurrence rates [100% and 50% respectively]. Odontogenic keratocyst is an aggressive cyst associated with high recurrence. Surgeons should decide on various modalities as per requirement of the case. Although resection carries least risk of recurrence, it should be limited to recurrent and aggressive OKCs. The outcomes of enucleation combined with peripheral ostectomy and chemical cauterization is reasonably acceptable
