Abstract

Background: Chronic suppurative otitis media (CSOM) is a common problem affecting middle ear and it’s commonly presented with chronic ear discharge and decreased hearing. Hearing problem in CSOM is primarily caused perforated tympanic membrane and in some cases by the presence of erosion of the ossicular chain. The study aimed to show the rate and site of ossicular chain erosion in patients with chronic suppurative otitis media underwent tympanomastoid surgery. Patient and methods: a cross sectional study conducted on 87 patients performed tympanomastoid surgery for chronic middle ear infection where their ossicular status has been assessed intraoperatively. Results: our study shows that 40% of the operated ears has at least a single bone erosion and the Incus bone was the most affected ossicle while the Malleus was the least one 54% and 14% respectively. No statistically significant difference was seen between bone erosion and gender as well as the side of operation. Conclusion: ossicular erosion is a common problem affecting patient with chronic suppurative otitis media and the surgeons should be aware about this pathology and they should have the proper skill to correct such problem.

鼓膜乳突手术患者听骨链侵蚀的部位和发生率

背景：慢性化脓性中耳炎（CSOM）是影响中耳的常见问题，通常表现为慢性耳部分泌物增多和听力下降。慢性化脓性中耳炎患者的听力问题主要是由鼓膜穿孔引起的，在某些病例中还会出现听骨链侵蚀。该研究旨在显示接受鼓室成形术的慢性化脓性中耳炎患者耳骨链受侵蚀的比例和部位。研究对象和方法：这是一项横断面研究，研究对象是 87 名因慢性中耳炎而接受鼓膜乳突手术的患者，术中对他们的听骨状况进行了评估。结果：我们的研究显示，40%的手术耳至少有一处骨侵蚀，其中受影响最大的听小骨是印骨，受影响最小的是耳郭，分别为 54% 和 14%。骨侵蚀与性别和手术侧之间没有明显的统计学差异。结论：听小骨糜烂是慢性化脓性中耳炎患者的常见问题，外科医生应了解这一病理现象，并掌握适当的技巧来纠正这一问题。
