Odontogenic Keratocyst/KCOT: Surgical Treatment Algorithm

Len Tolstunov, DDS, DMD

San Francisco, CA


Odontogenic keratocyst (OKC) has been one of the most controversial pathological entities in the maxillofacial region since it was first described by Philipsen in 1956. Various surgical techniques have been proposed for treating OKCs. These range from the more conservative procedures (eg, marsupialization, enucleation) to more aggressive approaches (eg, en bloc resection). Bases on the literature reports and clinical experience, the author proposes an algorithm for surgically treating OKC. This algorithm gives indications for the 3 main (marsupialization, enucleation, and resection) and 3 adjunctive (cryotherapy, Carnoy’s solution, and peripheral ostectomy) surgical techniques commonly used to treat OKC. A logical “decision tree” approach is emphasized. This presentation will be supported by a case report of combined treatment of OKC and mandibular defect with marsupialization, enucleation, iliac bone graft, and dental implants.

Learning Objectives

At the conclusion of this presentation, participants should be able to:

  1. Clear understanding of the position and classification of this lesion. Learn how and why
  2. Clear and logical understanding of the algorythm of treatment to get tid off the lesion
  3. How to treat a complex case and plan a multi-treatment modalities
