Middle ear aeration is a predictive indicator of myringoplasty's successful outcome and tympanometric ear canal volume is a novel investigation that can estimate the volume of middle ear cleft and mastoid air cells. Our aim of this study is to determine the role of tympanometric ear canal volume on myringoplasty outcome in Chronic Suppurative Otitis Media Patients. Prospective analysis involving 50 patients of CSOM was performed on patients undergoing myringoplasty from April 2022 to December 2023. Smokers, Patients with squamosal COM, Bilateral COM, Otitis Externa, and Revision surgery were excluded from the study. The successful outcome of surgery was defined as no tympanic membrane perforation on postoperative follow-up. Analysis was carried out using SPSS. V. 25 and P-value less than 0.05 was considered significant. A total of 50 patients were included in the study with a mean age of 24.4 ± 8.965 and male predominance. Overall graft uptake was 64%. Graft uptake had no significant statistical correlation with age, gender, type, location, or size of perforation. However, there is a significant effect of tympanometric ear canal volume of pathological ear and interaural tympanometric ear canal volume difference on graft uptake with p-values of 0.023 and 0.033 respectively. Tympanometric ear canal volume can predict middle ear aeration and the higher the interaural tympanometric canal difference more are the chances of successful graft uptake.
中耳通气是鼓膜成形术成功结果的预测指标，鼓室导纳测量法测量的耳道容积是一种新型检查方法，可估计中耳裂和乳突气房的容积。本研究的目的是确定鼓室导纳测量法测量的耳道容积在慢性化脓性中耳炎患者鼓膜成形术结果中的作用。对2022年4月至2023年12月接受鼓膜成形术的50例慢性化脓性中耳炎患者进行了前瞻性分析。吸烟者、鳞状上皮性慢性化脓性中耳炎患者、双侧慢性化脓性中耳炎患者、外耳道炎患者和翻修手术患者被排除在研究之外。手术成功的结果定义为术后随访时无鼓膜穿孔。使用SPSS v.25进行分析，P值小于0.05被认为具有统计学意义。共有50例患者纳入研究，平均年龄为24.4±8.965岁，男性占主导。总体移植物吸收率为64%。移植物吸收率与年龄、性别、穿孔类型、位置或大小无显著统计学相关性。然而，患耳的鼓室导纳测量法测量的耳道容积和双耳鼓室导纳测量法测量的耳道容积差异对移植物吸收率有显著影响，P值分别为0.023和0.033。鼓室导纳测量法测量的耳道容积可以预测中耳通气，双耳鼓室导纳测量法测量的耳道容积差异越大，移植物成功吸收的机会就越大。
