Abstract. In the last decades, rhinology has developed in a great manner concerning new surgical techniques and extending the use of compatible biomaterials in order to achieve normal morphology and normal functional aspect after surgery (endoscopic or open approach). Since biomaterials are integrated in biological active organs and systems, they have to be easily accepted by the receiver with no toxicity, inflammation or other side effects. The authors try to review all biocompatible materials used in several rhinological pathologies in order to obtain the best results after functional or reconstructive surgery. In rhinological surgery there are usually used homograft's but the use of biomaterials like alloplastics (silicone, high density polyethylene, polytetrafluoroethylene, etc.) has widely increased. The authors present their experience in endoscopic approach of choanal atresia using nasal stents, closure techniques for septal perforation using nasal splints, endoscopic drainage and sinus ventilation using balloon sinuplasty, lacrimal pathway obstruction using double margin stent and some materials used in cosmetic and reconstructive rhinoplasty.
