Abstract

BACKGROUND

Blepharoptosis operations are performed under local anaesthesia, and it is necessary to determine the location where the levator aponeurosis is fixed to the tarsus by checking opening and closing of the eyelids during surgery. Changes in posture during the operation affect the facial condition in various ways. This study was performed to clarify the differences in palpebral fissure height according to intraoperative head position.

METHODS

Sixty subjects (48 women and 12 men aged 20-76 years) were enrolled in the study. The palpebral fissure height of the dominant eye was measured in the head-neutral position and 30° head-down position.

RESULTS

The total fissure height in the 30° head-down position was lower than that in the head-neutral position.

CONCLUSIONS

The head-down position affects the patient's fissure height and may mislead the operator. Blepharoptosis operation under local anaesthesia should be performed with the patient in the head-neutral position.

摘要

背景

睑下垂手术在局部麻醉下进行，手术过程中需要通过检查眼睑的开合来确定提上睑肌腱膜固定于睑板的位置。手术过程中姿势的改变会以多种方式影响面部状况。本研究旨在阐明术中头部位置不同时睑裂高度的差异。

方法

60名受试者（48名女性和12名男性，年龄20 - 76岁）纳入本研究。在头部中立位和头部向下倾斜30°位测量优势眼的睑裂高度。

结果

头部向下倾斜30°位时的睑裂总高度低于头部中立位时。

结论

头部向下倾斜位会影响患者的睑裂高度，可能会误导手术操作者。局部麻醉下的睑下垂手术应在患者头部处于中立位时进行。
