目的探讨改良带蒂眶骨膜锚定术治疗固定性内下斜视的方法。方法12例固定性内下斜视均采取内直肌大量后徙,下直肌后徙,联合带蒂眶骨膜外直肌附着点锚定手术矫正。结果术后8例眼位原在位正位,2例残余内斜视,2例残余下斜视。结论此改良术式远期效果稳定;且不行外直肌缩短术,为同期手术解决内下斜视创造条件,并大大降低发生眼前段缺血的危险性。
Objective To explore the method of modified orbital periosteal anchoring for the treatment of intra-articular hypothalamic fixation. Methods 12 cases of fixed inferior inferior oblique rectum were taken after a large number of posterior rectus, rectus and rectus, combined pedicle orbital periosteal rectus muscle anchoring surgery to correct. Results Eight patients had orthophoria, 2 residual esotropia and 2 residual strabismus. Conclusions This improved surgical procedure has a long-term effect of stabilization; and no shortening of the lateral rectus abdominis, which creates the conditions for surgical treatment of inferior oblique strabismus and greatly reduces the risk of anterior segment ischemia.
