National and international tendencies to avoid nasal packing after FESS are closed related to the surgical surgery (atraumatic endoscopic surgery, avoidance of resection of turbinates, meticulose coagulation). At the end of each operation a benefit-risk-analysis should be performed, whether nasal packing is indicated and which one. In endonasal surgery only those conventional nasal packing materials should be used - if necessary - which have a smooth surface and minimize mucosal damage, potential worsening of wound healing and negative impact on patient comfort. So called hemostatic/resorbable materials are a first step to these direction. But they are critical, because these materials cause increased synechiae and sometimes foreign body reactions because of incorporation into the mucosa. Occlusion of the nose via simple taping of the nasal entrance is a simple and very effective method to create a moist environment to optimize endonasal wound healing or management of a dry nose.

Disturbed wound healing following dentoalveolar procedures may be due to various causes. Necrotizing inflammations with epitheloid cells may easily be mistaken for specific inflammations. Atypical granulomas represent a response to foreign body material (e.g., gelatin sponges). The possibility of sensitization with Gelastypt was tested using immunologic methods.
