Endoscopic Endonasal Surgery for Radicular Cyst

Abstract

We report three cases of large radicular cyst, successfully resected by endoscopic endonasal surgery. Radicular cysts were opend by partial resection from the medial wall of the maxillary sinus in the inferior meatus. This procedure is similar to the surgery for postoperative maxillary sinus cyst, therefore it is a simple technique for oto-rhino-laryngologists. This approach is very useful for large radicular cyst because it is less invasive to the patient than a conventional approach. Surgeons should pay attention to the residual cystic cavities and residual cyst walls, when performing this procedure.
