Canal wall down and canal wall up mastoidectomy represent two surgical approaches to middle ear cleft pathology. Very few studies have examined the effects of these procedures both on the patients' well being and on the resources needed to maintain that state. In this study the authors report the outpatient attendance pattern of canal wall down mastoidectomy patients METHODS: This is a retrospective case-note review of 101 patients who underwent a CWD mastoidectomy at Derriford Hospital, Plymouth, UK. All surgery was performed by the senior author (PCW-T) between 1985 and 1997. The main outcome measures were the frequency of outpatients' visits, clinical problems at visit and the percentage of discharged patients. RESULTS: The studied patients made a total of 1341 outpatient visits between November 1985 and December 1998 with an average of 13.3 visits per patient (median of 11 visits). Almost two thirds of the group still attend for regular follow up. The greatest number of visits occurred in the first 24 months after surgery. The commonest reasons for outpatient visits were the removal of the clinical features of chronic cavity inflammation. Residual/recurrent cholesteatoma, residual perforations and structural cavity problems were infrequent. CONCLUSION: CWD mastoidectomy carries an intrinsic morbidity resulting in a long term attendance in the outpatients.
开放式乳突根治术和完壁式乳突根治术是针对中耳裂病变的两种手术方法。很少有研究探讨这些手术对患者健康状况以及维持该状态所需资源的影响。在本研究中，作者报告了开放式乳突根治术患者的门诊就诊模式。
这是一项对101例在英国普利茅斯德里福德医院接受开放式乳突根治术患者的回顾性病例记录研究。所有手术均由资深作者（PCW-T）在1985年至1997年间完成。主要观察指标为门诊就诊频率、就诊时的临床问题以及出院患者百分比。
研究患者在1985年11月至1998年12月期间共进行了1341次门诊就诊，平均每位患者就诊13.3次（中位数为11次）。该组中近三分之二的患者仍在定期随访。就诊次数最多的是在手术后的前24个月。门诊就诊最常见的原因是消除慢性术腔炎症的临床症状。残余/复发性胆脂瘤、残余穿孔和术腔结构问题并不常见。
开放式乳突根治术存在内在的发病率，导致患者长期在门诊就诊。
