Odontogenic cysts represent a common form of pathology of the jaws, and the natural history, clinicopathologic findings, and appropriate management strategies are important to the oral and maxillofacial surgeon. Odontogenic cysts in the pediatric populations are important pathologic entities given their potential impact on the growth and development of the maxillofacial complex. Inappropriate management strategies can severely affect the form and function of the growing child. Categorizing pediatric odontogenic cysts into inflammatory or developmental causes provides a convenient way of conceptualizing these various entities and helps facilitate the appropriate diagnosis and the subsequent management., (Copyright © 2016 Elsevier Inc.

Purpose: This study describes the technique of lesion enucleation without capsule disruption combined with liquid nitrogen cryotherapy in the surgical treatment of keratocystic odontogenic tumors (KOTs)., Patients and Methods: Eight patients (9 KOTs) were included in the study. After enucleation, liquid nitrogen was applied twice for 1 minute, with 5-minute intervals between applications. The patients were followed up for 3 to 9 years., Results: There were no recurrences during the follow-up of 9 KOTs for up to 9 years. Only 1 patient had temporary reversible loss of lip sensation after treatment. There were no pathologic fractures. In all cases bone height at the surgical site was restored, and no patients needed bone reconstruction for post-treatment rehabilitation., Conclusions: This study confirmed the efficiency of KOT treatment enucleation without fragmentation combined with liquid nitrogen cryotherapy at the surgical site., (Copyright © 2011 American Association of Oral and Maxillofacial Surgeons.

Purpose: To analyze and discuss the demographic, clinical, and surgical aspects of 261 surgically treated keratocystic odontogenic tumors., Patients and Methods: A retrospective review was performed of all cases of treated keratocystic odontogenic tumors. Statistical analysis was used to search for associations among age, presenting symptoms, location, dimension, and locularity., Results: Keratocystic odontogenic tumors most commonly occurred in patients in the third and fourth decades of life. The ratio of males to females was 2:1. The mandibular angle region was the most frequently involved site. Significant associations were found between multilocular lesions and lesions larger than 31 mm (P < .00000005), a mandibular site and larger lesions (P < .05), patients younger than 41 years old and multilocular lesions (P < .05), and younger patients and larger lesions (P < .00005)., Conclusion: It is likely that most multilocular, larger (and probably aggressive) lesions are found in patients younger than 41 years of age., (Copyright © 2010 American Association of Oral and Maxillofacial Surgeons.
