Introduction: Keratocystic odontogenic tumours (KCOTs) are benign lesions of the jaw that are characterised by expansive growth and high rates of recurrence. Herein, we present a novel minimally invasive method for the surgical treatment of KCOTs.
Case presentation: We present a 49-year-old woman with a rare, large KCOT of the mandible extending from tooth 37 to tooth 47. A single enucleation procedure was selected as the surgical technique combined with a titanium plate. Teeth interfering with the cystic lumen were preserved. The bone surrounding the cyst was partially removed and rinsed with Carnoy's solution. Recurrence was observed 1year later between teeth 43 and 45, and was treated by single enucleation with Carnoy's solution. After the second operation, the teeth interfering with the KCOT still elicited a positive response to dental pulp testing. No further signs of recurrence were observed after a total observation period of 7 years.
Discussion: Various surgical interventions have been described for KCOTs. However, a general guideline for a specific surgical intervention has not yet been established owing to the heterogeneity of these tumours.
Conclusion: Immediate enucleation in combination with a titanium plate offers an effective surgical approach for the treatment of large KCOTs of the mandible without the need for radical tooth removal or resection of the afflicted side.
