A major risk of a<unk>  augmentation is that the<unk>  membrane could be pierced or ripped. Remedies, should this occur, include stitching the tear or placing a patch over it; in some cases, the surgery is stopped altogether and the tear is given time to heal, usually three to six months. Often, the<unk>  membrane grows back thicker and stronger, making success more likely on the second operation. Although rarely reported, such secondary intervention can also be successful when the primary surgery is limited to elevation of the membrane without the insertion of additional material. Besides tearing of the<unk>  membrane, there are other risks involved in<unk>  augmentation surgery. Most notably, the close relationship of the augmentation site with the sinonasal complex can induce<unk> itis, which may chronicize and cause severe symptoms.<unk> itis resulting from maxillary<unk>  augmentation is considered a Class 1 sinonasal complication according to Felisati classification and should be addressed surgically with a combined endoscopic endonasal and endoral approach. Beside<unk> itis, among other procedure related-risks include: infection, inflammation, pain, itching, allergic reaction, tissue or nerve damage, scar formation, hematoma, graft failure, oro-antral communication / oro-antral fistula, tilting or loosening of implants, or bleeding,
