Abstract

OBJECTIVES

The lateral meatoplasty is a well-described technique for widening the lateral external auditory meatus. After bony canalplasty, the external auditory meatus may need to be enlarged to accommodate an expanded tympanic ring. In this study, we introduce a novel meatoplasty technique for use during canalplasty and describe its efficacy in widening the external auditory meatus.

METHODS

Patients undergoing at least 180-degree bony canalplasty and mini-meatoplasty at a tertiary care facility were enrolled. Meatus diameter was measured before and after mini-meatoplasty using Shea aural speculums and Hegar dilators.

RESULTS

Nineteen patients were enrolled. Mean preoperative speculum size was 6.1 mm (range 3.5-7.5 mm). All postoperative speculum sizes were 8 mm (P < .0001). Mean preoperative and postoperative Hegar dilator sizes were 10.6 mm (range 7-14 mm) and 16.2 mm (range 13-19 mm), respectively (P < .0001). The mean increase in aural speculum and Hegar dilator sizes were 1.9 mm (range 0.5-3.5 mm) and 5.7 mm (range 3-10 mm), respectively (P < .0001).

CONCLUSIONS

The mini-meatoplasty is a novel and effective technique for widening the external auditory meatus after bony canalplasty.

摘要

目的

外侧皮瓣成形术是一种广泛应用于扩宽外侧外耳道的技术。完成骨性耳道成形术后，可能需要进一步扩大外耳道以容纳扩张后的鼓膜环。本研究中，我们介绍了一种新的皮瓣成形术，用于骨性耳道成形术，并描述了其扩宽外耳道的效果。

方法

在一家三级护理机构，我们招募了至少接受 180 度骨性耳道成形术和微型皮瓣成形术的患者。在微型皮瓣成形术前和术后，使用 Shea 耳镜和 Hegar 扩张器测量外耳道直径。

结果

共纳入 19 名患者。术前耳镜平均尺寸为 6.1mm（范围 3.5-7.5mm）。所有术后耳镜尺寸均为 8mm（P<0.0001）。术前和术后 Hegar 扩张器的平均尺寸分别为 10.6mm（范围 7-14mm）和 16.2mm（范围 13-19mm）（P<0.0001）。耳镜和 Hegar 扩张器的平均增大尺寸分别为 1.9mm（范围 0.5-3.5mm）和 5.7mm（范围 3-10mm）（P<0.0001）。
