Emprego de marsupialização para tratamento de cisto odontogênico ortoceratinizado extenso em mandíbula: relato de caso

Abstract

The orthokeratinized odontogenic cyst (OOC) is a cyst of unusual development of the jaws and which were considered a distinct entity of odontogenic keratocysts (OKs), since they present a less aggressive behavior. The recommended form of treatment for OOC usually involvesconservative measures in view of its lower recurrence rate in relation to odontogenic keratocysts. Histologically, OOCs are developmental cysts coated with orthoceratinized epithelium and consist of a uniform layer of regular stratified squamous epithelium, with the basal layer exhibiting cells in palisades or flat, with nuclear hyperchromatism. The purpose ofthis study is to report a clinical case of a patient attended at the Bucomaxillofacial and Stomatology Clinic of the Hospital Metropolitano Odilon Behrens (HMOB), with an extensive OOC in the mandible, treated by marsupialization and clinical and radiographic follow-up in theperiod of 07 years. The relevant literature on the pathological clinical features of OOC has been reviewed. In the literature, no study was found that used OOC marsupialization as the only treatment technique. Therefore, this is an unprecedented study that has been successfulin treatment.Keywords: Odontogenic cysts. Orthokeratinized odontogenic cyst. Odontogenic keratocyst.Orthokeratinization.
