When oozing is unsufficient to swell the packing , water is applied directly using a narrow - gauge hyperdermic needle 當(dāng)分泌物不足以使填塞物膨脹時(shí)可以用細(xì)針向內(nèi)注入少許水。
Due to the size of the defect , a fragment of bone is introduced to support the mucosal graft . strength of the repair is verified by increasing intercranial pressure with the valsalva maneuver , and it is seen to be watertight . rapid - setting fibrin glue is applied , and a second layer of mucosa is applied over this 由于瘺孔較大,置入一些骨的碎片以支持填塞物,通過valsalva法咽鼓管吹氣法增加顱內(nèi)壓可以觀察修補(bǔ)的牢固性,可以看到?jīng)]有泄漏,利用可以快速固定的纖維蛋白膠進(jìn)行固定,其上鋪上一層粘膜,然后再用膠水進(jìn)行固定。
