Postoperative Wound Infiltration with Local Anaesthetic after Enucleation of a Large Periapical Cystic Lesion: A Case Report

The periapical cyst arises from epithelial remnants stimulated to proliferate by an inflammatory process originating from pulpal necrosis of a non-vital tooth. This condition is usually asymptomatic but if the cyst does become large, symptoms such as swelling may be observed. Although small cystic lesions will typically heal with nonsurgical endodontic therapy, larger lesions may need surgical intervention. Effective postoperative analgesia is important in surgical enucleation of large periapical cysts from the patient’s viewpoint and can also improve clinical results. Pain free postoperative healing is desired by every patient. Wound infiltration with local anaesthetics is a simple, effective and inexpensive means of providing good analgesia for a variety of surgical procedures without any major side-effects. Continuous local anaesthetic infusion of a surgical wound using a catheter can provide a longer duration of analgesia.
