Transnasal endoscopic marsupialization for a large midline maxillary odontogenic keratocyst in a 6-year-old child

An odontogenic keratocyst is a histologically distinct lesion that is thought to arise from basal cells of the oral epithelium, usually occurring in the posterior portion of the mandible or the mandibular ramus. We report on a large odontogenic keratocyst that presented as nasal airway obstruction in a 6-year-old boy. To our knowledge, this is the youngest patient for whom a midline odontogenic keratocyst in the anterior maxillary region has been documented in the English literature. We designed a less-invasive surgical approach for transnasal endoscopic marsupialization instead of enucleation of this large pediatric odontogenic keratocyst.
