Özet

Introduction:
Odontogenic keratocysts are benign yet invasive lesions known for their aggressive growth potential and high recurrence rates. Treatment options include enucleation, marsupialization, resection, and the adjunctive application of Carnoy’s solution. However, when critical anatomical structures such as the sinus and nasal floor are involved, conservative approaches may be preferred.

Case Presentation:
A 60-year-old female patient was diagnosed with a large keratocyst extending from the anterior maxilla to the premolar-molar region, causing destruction in the nasal floor and maxillary sinus walls. A biopsy taken for preliminary diagnosis confirmed the lesion as an odontogenic keratocyst. The patient was scheduled for treatment under local anesthesia using a conservative surgical approach.

Treatment and Follow-up:
Three fenestrations were created in selected regions of the cyst, followed by enucleation. Carnoy’s solution was not used due to the exposure of the maxillary sinus and nasal floor. Postoperative follow-up with panoramic radiographs at 3, 6, and 12 months revealed a reduction in the cyst cavity and initiation of bone healing.

Conclusion:
Although aggressive surgical interventions and chemical agents can reduce recurrence rates in the management of keratocysts, conservative approaches can yield successful outcomes when critical anatomical structures are involved. This case demonstrates that enucleation performed with a minimally invasive technique provided satisfactory healing.
