The posterior wall of external auditory canal, mastoid cavity and chain of ossicles were reconstructed by homologous costal cartilage. Results: 66 ears of 71 cases are near normal structure followed up 6 months to 5 years after operations.
结果：71耳术后经6个月～5年随访，66耳重建中耳腔接近正常生理结构，听力提高15dB以上或达应用水平55耳，占775%（55/71）；
Cholesteatomas was found in 12 cases with chronic otitis media, that 3D images exhibited varying degrees of destruction of the auditory ossicles, and the display ability of SSD 3D image was slightly better than that of MIP 3D image.
18例中耳炎患者中12例胆脂瘤形成，3D重建显示有不同程度的听小骨破坏，SSD3D的显示效果略好于MIP3D。
External auditory canal and mastoid process were involved in 10 cases, squamous and petrous parts in 8 cases, and middle ear in 7 cases on CT scans. Destruction of ossicles and bony labyrinth were detected in 2 cases, respectively.
CT发现10例都累及外耳道和乳突，8例并累及岩部和鳞部，7例累及中耳，听小骨及内耳骨迷路破坏各2例。
The common complications were inflammation and cholesteatoma. Secondary cholesteatoma occurred in 3 cases (18.75%), which were respectively located at external auditory canal, mastoid process and attic-mastoid sinus with bony destruction of adjacent ossicles and superior semicircular canal.
常见并发症为炎症、胆脂瘤，3例（18.75%）继发胆脂瘤分别位于外耳道、乳突及上鼓室乳突窦，其中上鼓室乳突窦胆脂瘤破坏邻近听小骨、上半规管。
Methods: 71 ears of post- mastoidectomy (discharging 53 ears and dried up 18 ears) were undergone with reconstruction of middle ear. The posterior wall of external auditory canal, mastoid cavity and chain of ossicles were reconstructed by homologous costal cartilage.
用同种异体肋软骨为外耳道后壁重建材料、乳突充填材料、听骨链重建材料，对71例乳突根治术后耳(流脓53耳，干耳18耳)作了中耳重建术。
Twenty-four ears treated by canaloplasty of external auditory meatus and tympanoplasty, hammer and incus hypoplasia in 19 ears, stapes abnormity were demonstrated in 11 ears, ossicles absence in 3 ears, vestibular window clausura in 1 ears.
24耳行手术治疗，术中发现锤、砧骨发育不全19耳，镫骨畸形11耳，镫骨缺失3耳，前庭窗闭锁1耳。
In the operation, temporal fascia was used to repair the drum and self cortex of mastoid bone or artificial porcelain auditory ossicles were used to reconstruct the ossicular chain.
采用颞肌筋膜修补鼓膜，以自体乳突骨皮质或陶瓷人工听骨重建听骨链。
