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).References
