SP-11 Decompression of Large Cystic Periapical Lesions: A Conventional Approach in the New Era

CE Hours: 0.75

Description: Managing large cystic periapical lesions presents significant challenges for clinicians, especially when non-surgical treatment or retreatment options prove ineffective. Surgical intervention involving debridement and apical resection may be deemed contraindicated due to factors such as the proximity to vital anatomical structures, the risk of damage to adjacent teeth, and compromised healing associated with significant bony defects. Despite these challenges, decompression offers a minimally invasive treatment alternative that is frequently overlooked in modern dentistry. This presentation aims to explore the indications and advantages of decompression in treating large cystic periapical lesions. Through clinical case studies and follow-ups, we will demonstrate essential steps, including pre-operative assessment using cone-beam computed tomography (CBCT) scans, needle aspiration-irrigation techniques, and the placement of a Penrose drain. Furthermore, we will review pertinent literature to highlight the biological principles, clinical efficacy, and long-term outcomes associated with decompression.

Learning Objectives:  

• Describe the clinical indications for decompression and conduct a preoperative assessment using conebeam computed tomography (CBCT) scans.
• Perform aspiration irrigation techniques and utilize a Penrose drain for decompression.
• Evaluate the outcome of decompression in treating large cystic periapical lesions.
