摘要

背景和目的乙状前动脉皮瓣（AEA）是一种常用于修复鼻中隔穿孔（SP）的有蒂鼻内皮瓣。后部切口的操作最为复杂。研究的主要目的是确定完全覆盖鼻中隔前部穿孔的 AEA 后方切口（PI）的最小高度。在 10、20、30 和 40 毫米的高度上逐步制作 AEA 皮瓣的 PI。结果根据 PI 的长度得出以下结果：PI=10毫米：SP被部分覆盖，AR为45º。PI = 20 毫米：PI = 30 毫米和 40 毫米：这项研究表明，乙状动脉前皮瓣包括鼻底和下肉眼黏膜，结合 20 毫米的后切口，可以充分覆盖前 SP 的所有边缘，直至鼻中隔的 1a 区域。

Enhancing the coverage and rotation of anterior ethmoidal artery flap for septal perforation closure: Insights from a flap design study

Background and objectives

The anterior ethmoidal artery flap (AEA) is a pedicle endonasal flap frequently used to repair septal perforations (SP). The posterior incision is the most complex to perform. The primary objective was to determine the minimum height of the posterior incision (PI) of an AEA completely cover an anterior septal perforation.

Materials and methods

A cadaveric specimen was sectioned in the sagittal plane and a SP of 1 cm was created anteriorly. The PI of the AEA flap was made progressively at a height of 10, 20, 30, and 40 mm. The complete closure of the SP and the angle of rotation (AR) of the flap were assessed.

Results

According to the length of the PI the following results were obtained: PI = 10 mm: The SP was covered partially, and the AR was 45º. PI = 20 mm: The SP was fully covered, and the AR was 63º.

PI = 30 mm and 40 mm: The SP was fully covered with redundant tissue.

This study shows that an anterior ethmoidal artery flap that includes the nasal floor and the inferior meatus mucosa combined with a posterior incision of 20 mm could result in adequate coverage of all margins of an anterior SP up to area 1a of the septum.
