[Odontogenic and nonodontogenic jaw cysts: experience in 25 cases]

We retrospectively evaluated the patients with jaw cysts treated at our center.

The study included 25 patients (14 males, 11 females; mean age 33+/-19 years; range 7 to 69 years) who underwent surgery for odontogenic or nonodontogenic jaw cysts.

The most common presentation was a swelling in the jaw with or without dental problems. Involvement was in the mandible in 18 patients, and in the maxilla in seven patients. The lesions consisted of eight radicular, six dentigerous, two nasoalveolar, two globulomaxillary cysts, and three keratocysts. Four patients had gingival, nasopalatine, residual, and median mandibular cysts, respectively. Marsupialization, curettage, extensive burring, enucleation, or marginal resection were performed depending on pre- and intraoperative findings. The defects were repaired with a corticocancellous iliac bone block graft in three patients and cancellous iliac bone chips in five patients. During a mean follow-up of 14 months (range 12 to 46 months), recurrence was seen in only one patient with a keratocyst.

A good preoperative assessment, complete removal of the cystic lesion, and close radiographic follow-up are essential for a successful outcome in jaw cysts. In selected cases, reconstruction of the defects with autogenous corticocancellous iliac bone graft yields highly satisfactory results.
