Abstract:
For the nasal anatomic structure and characteristics of endoscopic sinus surgery, nasal packing is the main method for nasal hemostasis.At present, there are two kinds of nasal packing biomaterials:absorbable and non-absorbable materials.Each kind of materials has their own characteristics.Merocel highly expansive sponge is a kind of non-absorbable material.It is made of polymeric material and has a high hydrophilicity.It is expansive uniformly in the nasal cavity, and gives the same pressure to all parts, especially the lacunae.Its texture is flexible, and it has small damage to the nasal mucosa.The texture of calcium alginate dressing is soft, and it has no toxicity.It has little stimulation to the nasal cavity and small damage to the nasal mucosa.It has slight local reaction and no obviously pain response after packing.Its efficacy on hemostasis is good.Gelatin sponge is a kind of absorbable material.It has high efficiency on hemostasis and few side reactions.It has protection and promotion of mucosa healing, as well as anti-inflammation.Besides those mentioned above, there are many other common materials, including vaseline gauze and Rhine haemostatic materials.By understanding the characteristics of the packing materials, we should select the different kinds of materials in accordance with the type of hemorrhage and range of operation.
