Summary
Aneurysmal bone cysts in the jaw are similar to those in other bones. Surgical excision with clear margins is more effective than curettage for preventing recurrence of primary jaw cysts.
Area of Science:
- Oral and Maxillofacial Surgery
- Skeletal Pathology
- Oncology
Background:
- Aneurysmal bone cysts (ABCs) are benign, expansile, and often locally destructive bone lesions.
- Histologically, jaw ABCs are identical to those in other skeletal sites.
- ABCs can be primary or secondary to other bone pathologies.
Purpose of the Study:
- To compare the recurrence rates of aneurysmal bone cysts of the jaws treated with different surgical methods.
- To evaluate the efficacy of curettage versus surgical excision for primary jaw ABCs.
Main Methods:
- Review of cases of aneurysmal bone cysts of the jaws.
- Analysis of treatment modalities including curettage and surgical excision.
- Assessment of recurrence rates based on treatment type and margin status.
Main Results:
- Aneurysmal bone cysts of the jaws show a 2:1 to 3:1 predilection for the mandible over the maxilla.
- Curettage is associated with a high rate of lesion recurrence.
- Surgical excision with negative margins significantly reduces the recurrence incidence of primary jaw ABCs.
Conclusions:
- Surgical excision with clear margins is the preferred treatment for primary aneurysmal bone cysts of the jaws.
- Histological similarity underscores the importance of consistent diagnostic criteria across different anatomical sites.
- Understanding the primary versus secondary nature of jaw ABCs is crucial for tailoring treatment and predicting outcomes.
