中耳胆脂瘤手术ICD-9-CM-3编码分析

手术治疗特别是中耳病变切除联合鼓室成形术是目前根治中耳胆脂瘤最主要的方法,依据2012年版的中耳炎手术分型指南内容,按照手术对外耳道后壁和鼓窦上鼓室侧壁处理方式不同,中耳病变切除具体类型和对应ICD-9-CM-3编码为:完壁式乳突根治术20.4900x009、开放式乳突根治术20.4900x008、完桥式乳突根治术20.49和上鼓室鼓窦切开术20.4900x007等,为避免上述手术编码的混淆,编码员应掌握每种术式的具体内涵。同时对于重要的其它手术操作如鼓室成形术19.4~19.5、耳甲腔成形术18.79、外耳道后壁重建术18.6和乳突缩窄术20.92等也不能漏编和多编。编码员应加强中耳结构和手术知识的学习,当不能确定手术具体类型时,应与耳鼻喉医师沟通,确定正确手术类型和内容时方可编码。

Endoscopic cartilage tympanoplasty: full thickness and partial thickness tragal graft

IntroductionCartilage is the grafting material of choice for certain disorders of the middle ear. The indications for its routine use remain controversial due to the possible detrimental effect on post-operative hearing.ObjectiveThe present study was carried out to report a personal experience with “tragal cartilage shield” tympanoplasty to compare the results, in terms of graft uptake and hearing improvement, of endoscopic cartilage shield technique using either partial thickness or full thickness tragal cartilage for type 1 tympanoplasty and to highlight the tips for single-handed endoscopic ear surgery.MethodsFifty patients with safe chronic suppurative otitis media, assisted at out-patient department from February 2014 to September 2015 were selected. They were randomly allocated into two groups, 25 patients were included in group A where a full thickness tragal cartilage was used and 25 patients included in group B where a partial thickness tragal cartilage was used. Audiometry was performed 2 months after the surgery in all cases and the patients were followed for one year.ResultsOut of the total of 50 patients 39 (78%) had a successful graft take up, amongst these 22 belonged to group A and 17 belonged to the group B. The hearing improvement was similar in both groups.ConclusionThis study reveals that endoscopic tragal cartilage shield tympanoplasty is a reliable technique; with a high degree of graft take and good hearing results, irrespective of the thickness. Furthermore, the tragal cartilage is easily accessible, adaptable, resistant to resorption and single-handed endoscopic ear surgery is minimally invasive, sutureless and provides a panoramic view of the middle ear.     

Type I Tympanoplasty: surgical success and prognostic factors

ObjectivesTo evaluate success rate of type I tympanoplasty in adults and to investigate the importance of selected prognostic factors on graft uptake.Material and methodsRetrospective medical chart review of 155 patients who underwent Type I Tympanoplasty, in our department, from January 2013 to December 2017. Graft uptake rate was evaluated and the effects of prognostic factors on surgical outcome such as sex, smoking and otological surgery history, status of the contralateral ear, size and location of the perforation, middle ear mucosa status, surgical approach and graft material. Preoperative and postoperative audiometric data were collected, and the functional success was determined.ResultsThe overall surgical anatomical success rate was 75%. Analysis of the selected variables, identified as independent prognostic factors of anatomical unsuccess (95% CI): smoking (OR = 3.29, p < .01), middle ear tympanosclerosis (OR = 2.96; p = .04). Perforations above 50% of the tympanic membrane area had a borderline effect on graft uptake (p = .05). There was a significative improvement in the average air conduction thresholds of 7.44 dB and an ABG closure rate at 10 dB and 20 dB was achieved in 47% and 84.5%, respectively. Patients who received temporalis fascia graft had similar hearing gain compared to patients who underwent cartilage tympanoplasty (7.7 vs. 7.3 dB, p = .79).ConclusionType I tympanoplasty is an effective and safe procedure with a high anatomical success rate in the treatment of mucosal COM. Poorer outcomes were found in patients with smoking habits, in those with tympanosclerosis of middle ear mucosa and in larger perforations. These prognostic factors should be considered in surgical planning and patients should be advised to quit smoking. Tympanoplasty with cartilage graft had a hearing outcome comparable to temporalis fascia graft and should be considered in high-risk patients.     

持续灌流模式耳内镜下Ⅲ、Ⅳ型鼓室硬化症手术疗效分析

目的探讨采用持续灌流耳内镜手术模式(CIM-EES)一期鼓室成形术治疗Ⅲ、Ⅳ型鼓室硬化症的临床疗效。方法2019.3-2020.9对17例(21耳)Ⅲ、Ⅳ型鼓室硬化症患者,在持续灌流模式耳内镜下采用外嵌法,一期行Ⅱ型鼓室成形术,观察分析手术时间,鼓膜愈合成功率,并比较术前及术后6个月平均气、骨导听阈(PTA)及气骨导差(A-B gap)。结果17例患者(21耳)术后鼓膜均一期完全愈合。手术时间平均为60.6±7.0min,术前平均气导听阈54.70±10.38 dB HL,术后6个月平均气导听阈35.24±11.66 dB HL,差异具有统计学意义(P<0.001)。术前及术后6个月平均气骨导差分别为34.93±9.30 dBHL和15.65±7.07 dB,差异具有统计学意义(P<0.001)。术前、术后骨导平均听阈差异无统计学意义(P>0.05),术后无患者出现皮瓣缺血坏死及外耳道狭窄。未出现感音神经性耳聋、面瘫及眩晕并发症。结论CIM-EES可以针对性解决传统耳内镜手术出血起雾污染镜头、热损伤等缺陷,提高手术流畅性及安全性。尤其对于Ⅲ、Ⅳ型鼓室硬化症手术,在持续灌流模式下可以抵近观察并精细清理镫骨周围硬化灶,有助于一期完成听骨链重建。近期疗效满意,远期疗效尚有待进一步随访观察。相对于内植法和外植法,外嵌法是一种新的技术改良,可以最大程度维持鼓室腔容积,减少粘连及听骨链移位的发生。     

Comparison of endoscopic transcanal and microscopic approach in Type 1 tympanoplasty

IntroductionEndoscopic tympanoplasty is a minimally invasive surgery that may be performed via a solely transcanal approach. The use of endoscopes in otologic procedures has been increasing worldwide. The endoscopic approach facilitates the transcanal tympanoplasty, even in patients having the narrow external ear canal with an anterior wall protrusion.ObjectivesThe present study aimed to compare the surgical and audiological outcomes of endoscopic transcanal and conventional microscopic approach in Type 1 tympanoplasty.MethodsThe graft success rates, hearing outcomes, complications, and duration of surgery in patients who underwent endoscopic and microscopic tympanoplasty between October 2015 and April 2018 were retrospectively analysed.ResultsGraft success rates were 94.8 per cent and 92.9 per cent for the endoscopic and microscopic group, respectively (p > 0.05). Postoperative air-bone gap values were improved significantly in both groups (p < 0.001). The average duration of surgery was significantly shorter in the endoscopic group (mean 34.9 min) relative to the microscopic group (mean 52.7 min) (p < 0.05). The average hospitalization period was 5.2 h (range 3–6 h) in Group I whereas it was 26.1 h (range 18–36 h) in Group II (p < 0.05).ConclusionThe endoscopic transcanal tympanoplasty approach is a reasonable alternative to conventional microscopic tympanoplasty in the treatment of chronic otitis media, with comparable graft success rates and hearing outcomes.
