Odontogenic keratocysts (OKC) are aggressive cysts with a high recurrence potential. Treating them with surgical enucleation procedures alone is associated with high recurrence rates; therefore, additional or supportive treatment approaches, such as peripheral osteotomy, cryotherapy, and chemical solutions, are warranted. The objective of the present review was to evaluate the existing literature on the efficacy of chemical approaches, such as Carnoy’s solution (CS), in preventing recurrence after the enucleation of OKC. An electronic search was conducted on PubMed, Scopus, and Google Scholar databases to find articles published from January 2010 to December 2022 by using the Medical Subject Headings (MeSH) terms “Odontogenic Keratocyst” “Carnoy’s Solution,” “Treatment,” and “Enucleation.” Articles published in the English language were selected for the study. The PICOS criteria (population: patients with non-syndromic OKC with histopathological diagnosis and a minimum follow-up of six months; intervention and comparison: enucleation followed by adjunctive chemical therapy and standard procedure; outcome: recurrence rates; study design: retrospective and prospective studies, randomized controlled trials, and case series involving at least 10 cases of OKC) were employed. Studies involving syndromic (nevoid basal cell carcinoma) cases were excluded from the search. Seventeen studies fulfilled the inclusion criteria and the majority of them were retrospective studies, with a few case series. OKC was found more frequently in the mandible, with a recurrence rate of 11%, when treated with CS following enucleation after four years of follow-up. Modified Carnoy’s solution (MC) was used in two studies. The mean follow-up period was 44 months. Based on our findings, adjuvant therapy using a chemical approach following enucleation is a more effective and beneficial modality for the treatment of OKC.

Objectives:Evaluation of clinical presentation of cystic lesions of the maxillofacial region, their relation to radiological picture, and treatment planning so as to plan and execute a patient need based treatment modality after co-relating it to the eventual histopathological diagnosis.Methods:25 cases with clinico-radiological diagnosis of a cyst were selected and treated, and the diagnosis was co-related to the eventual histopathological diagnosis. The patients were followed up for at least 3 months (3-12 months). An attempt was made to underline patient and lesion related variables having a bearing on the choice of treatment modality in each case.Results:Out of 25 patients, 28% were females and 72% males. Commonly affected age groups were 11-20 (40%) and 31-40 years (24%). 76% of 25 patients complained of swelling on the first visit. 96% lesions were related to jaws, of which 15 were in the mandible and 9 were in the maxilla. 58.33% bone lesions had cortical expansion. 92% lesions were confirmed to be cysts histopathologically. Two were ameloblastomas. 80% patients underwent enucleation with various adjunctive procedures. 32% patients faced temporary post operative complications. No recurrences were observed. Radiological presentation of lesions and patient's age were found to be the two most important radiological and clinical variables affecting treatment planning.Conclusions:A comprehensive patient need based treatment plan can be reached only after taking various patient and lesion related variables (which may manifest as clinical, radiological or histological parameters) into consideration.
