Odontogenic tumor, benign

Last edited: 4/16/2026

Overview

Keratocystic odontogenic tumor (KCOT) is a benign odontogenic neoplasm characterized by its aggressive behavior, frequent recurrence, and potential for local invasion, particularly into structures like the maxillary sinus 1.

Diagnosis

  • Cystic lesion with a bony capsule often found in the mandible or maxilla 1.
  • Radiographic features include well-defined borders, multilocular appearance, and association with impacted teeth 1.
  • Histopathological confirmation required, showing palisading basaloid cells surrounding ghost cells 1.
  • Management

  • Surgical excision: Radical surgical removal is recommended to minimize recurrence, often requiring multidisciplinary collaboration between oral surgeons and otorhinolaryngologists for complex cases 1.
  • Endoscopic techniques: Consideration of endoscopic approaches by oral surgeons to achieve minimally invasive yet radical treatment 1.
  • Recurrent cases: Previous conservative surgeries may necessitate more extensive approaches, such as bidirectional surgical access 1.
  • Special Populations

  • No specific guidance: The provided abstracts do not offer detailed recommendations for management in pregnancy, pediatrics, elderly patients, or those with comorbidities 1.
  • Key Recommendations

  • Multidisciplinary surgical approach for KCOT invading critical structures like the maxillary sinus to ensure radical removal and minimize invasiveness (Evidence: Expert opinion 1).
  • Consider endoscopic techniques in the surgical management of KCOT by oral surgeons to enhance minimally invasive outcomes (Evidence: Expert opinion 1).
  • Radical excision is crucial for reducing recurrence rates, especially in recurrent cases requiring comprehensive surgical strategies (Evidence: Expert opinion 1).
