概括

在可活的骨上部结构中,部分骨置换假体 (PORP) 在先天中耳异常的非可活性病例中显示出比全骨置换假体 (TORP) 更好的气骨间隙闭合. 更精细的分类可能会改善外科手术的结果.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
手术创新在外科创新.
听力学听力学是指听力学.

背景情况:

生产中耳异常 (CMEA) 存在复杂的外科手术挑战,特别是III类病例.
斯泰普斯超结构完整性是影响骨造形结果的关键因素.
目前的分类可能不能完全指导在III类CMEAs中的假肢选择.

研究的目的:

在III类CMEAs中,评估部分骨置换假肢 (PORP) 与全骨置换假肢 (TORP) 的手术结果.
为了将结果与STAPES超级结构完整性相关联.
建议对III类CMEAs进行改进的Teunissen-Cremers分类.

主要方法:

对46名患有III类CMEAs的患者进行了49只耳朵的回顾性队列研究,这些患者接受了骨科整形 (2012-2024年).
患者分为可活性 (完好无损/轻微失塑性超结构;PORP) 和不可活性 (严重失塑性/缺失超结构;TORP) 的组.
排除标准:修复手术,其他CMEAs,<6个月的随访.

主要成果:

术前的人口统计和听力值在各组之间是可比的.
在可行的 (PORP) 组 (80.8%) 与不可行的 (TORP) 组 (52.2%;P=.033) 相比,在10dB以内显著更好的空气-骨隙 (ABG) 关闭.
术后并发症在各组之间是相似的.

结论:

使用PORP在可活的形上层结构中进行骨干整形,可以在不可活的情况下获得比TORP更好的ABG闭合.
一个精细的Teunissen-Cremers分类 (可行的IIIa1,不可行的IIIa2) 可以提高假肢选择和预后评估.
需要进一步的研究来澄清基线听力差异对结果的影响.

The Auditory Ossicles

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Anatomy of the Ear

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
