作者用保存于0.5％福尔马林溶液中的牛胚胎软骨和角膜作为乳突和鼓室乳突成形术的移植物。共观察60例患者:上鼓室炎和上中鼓室炎56例,急性化脓性中耳乳突炎4例。用牛胚胎软骨填塞乳突术腔,其中51例为一期成形术,4例为术后1个月的延期成形术,5例为后期乳突成形术。14例同时施行了鼓室乳突成形术,并甩劈开的角膜移植片覆盖乳突腔内的软骨以形成鼓窦,保证新鼓室的含气量。术后55例伤口一期愈合;5例化脓,与过早去除引流有关。1例施行手术,4例保守治疗使化脓消失。术后5年间未发现生物学组织排斥现象。55例干耳,5例出现一次咽鼓管性中鼓室炎急性变,用保守治疗而缓解。听力学和前庭功能检查未发现胚胎软骨移植物对内耳有不良影响。14例鼓室乳突成形术患者,术
The authors used bovine embryonic cartilage and cornea preserved in 0.5% formalin solution as mastoid and tympanoplasty implants. A total of 60 patients were observed: upper tympanitis and upper middle tympanitis in 56 cases, acute suppurative otitis media in 4 cases. Cattle embryo cartilage stuffed mastoid cavity, of which 51 cases of a plastic surgery, 4 cases of postoperative 1 month postoperative plastic deformation, 5 cases of mastoid process. In 14 cases, tympanoplasty was performed at the same time, and the split corneal graft covered the cartilage in the mastoid cavity to form the sinuses to ensure the gas content of the new tympanic cavity. 55 cases of wound healing after a period of 5 cases of suppuration, and premature removal of drainage related. One patient underwent surgery and 4 patients were cured by conservative treatment. No rejection of biological tissue was found after 5 years. 55 cases of dry ears, 5 cases of a case of eustachian tube acute tympanitis, with conservative treatment and ease. Audiography and vestibular function tests found no adverse effects of embryonic cartilage grafts on the inner ear. 14 cases of tympanoplasty patients, surgery
