To evaluate the use of ear endoscopy in the postoperative management of open mastoidectomy cavities, and to test whether ear endoscopy improves inspection and cleaning compared with ear microscopy.
Prospective study. Thirty-two ears were divided into two groups: group 1, examination and cleaning of mastoid cavities under endoscopic visualization after microscopic standard ear cleaning; group 2, examination and cleaning of mastoid cavities under microscopic visualization after endoscope-assisted ear cleaning. We assessed the ability of each method to provide exposure and facilitate cleaning, comparing the benefits of microscopy and endoscopy when used sequentially and vice-versa.
Endoscopy provided additional benefits for exposure in 61.1% of cases and cleaning in 66.7%. Microscopy provided no additional benefits in terms of exposure in any case, and provided added benefit for cleaning in only 21.4% of cases.
For outpatient postoperative care of open mastoidectomy cavities, ear endoscopy provides greater benefit over ear microscopy than vice-versa. In over half of all cases, endoscopy was able to expose areas not visualized under the microscope. Furthermore, in two-thirds of cases, endoscopy enabled removal of material that could not be cleared under microscopy. Ear endoscopy was superior to microscopy in terms of enabling exposure and cleaning of hard-to-reach sites, due to its wider field of vision.
Ear endoscopy is a feasible technique for the postoperative management of open mastoidectomy cavities. Ear endoscopy provided superior advantages in terms of exposure and aural cleaning compared with microscopy.
评估耳内镜在开放式乳突切除术后术腔管理中的应用，并测试与耳显微镜相比，耳内镜是否能改善检查和清理效果。
前瞻性研究。32只耳朵被分为两组：第1组，在显微镜下进行标准耳部清理后，在内镜直视下检查和清理乳突腔；第2组，在内镜辅助耳部清理后，在显微镜直视下检查和清理乳突腔。我们评估了每种方法提供暴露和便于清理的能力，比较了依次使用显微镜和内镜的益处，反之亦然。
内镜在61.1%的病例中为暴露提供了额外益处，在66.7%的病例中为清理提供了额外益处。显微镜在任何情况下都未在暴露方面提供额外益处，仅在21.4%的病例中为清理提供了额外益处。
对于开放式乳突切除术后的门诊护理，耳内镜比耳显微镜提供了更大的益处。在超过一半的病例中，内镜能够暴露显微镜下无法看到的区域。此外，在三分之二的病例中，内镜能够清除显微镜下无法清理的物质。由于视野更宽，耳内镜在暴露和清理难以到达的部位方面优于显微镜。
耳内镜是开放式乳突切除术后术腔管理的一种可行技术。与显微镜相比，耳内镜在暴露和耳部清理方面具有明显优势。
