PURPOSE
We used superior oblique luxation and trochlear luxation as new surgical procedures to treat acquired Brown's syndrome and superior oblique muscle overaction.
METHODS
We studied nine patients (11 eyes) who underwent trochlear surgery between 1988 and 1993. Four patients had acquired Brown's syndrome and five had superior oblique muscle overaction. In five patients (six eyes) the trochlea was incised to luxate the superior oblique tendon out of the trochlea. In four patients (five eyes) the trochlea was luxated out of its fossa via a periosteal approach without opening the trochlea itself.
RESULTS
The mean follow-up was 18 months (range, nine to 33 months). Postoperatively, eight patients showed subjective and objective improvement. One patient with painful traumatic acquired Brown's syndrome had no objective improvement but obtained relief of pain.
CONCLUSIONS
These new techniques are a successful alternative in the treatment of acquired Brown's syndrome and superior oblique muscle overaction.
目的
我们采用上斜肌脱位术和滑车脱位术作为新的手术方法来治疗后天性布朗综合征和上斜肌亢进。
方法
我们研究了1988年至1993年间接受滑车手术的9例患者（11只眼）。4例患有后天性布朗综合征，5例患有上斜肌亢进。5例患者（6只眼）切开滑车以使上斜肌腱自滑车脱位。4例患者（5只眼）通过骨膜入路使滑车自其窝脱位，未打开滑车本身。
结果
平均随访18个月（范围9至33个月）。术后，8例患者主观和客观症状均有改善。1例患有疼痛性创伤性后天性布朗综合征的患者客观上无改善，但疼痛得到缓解。
结论
这些新技术是治疗后天性布朗综合征和上斜肌亢进的一种成功的替代方法。
