tendon expansion with fascia lata in treatment of a-pattern strabismus due to superior oblique overaction

چکیده
b ackground: in 1991, wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. originally, this procedure has been performed with silicone band expander. the aim of this study was to report the results of treatment of a series of patients with a-pattern strabismus associated with overacting superior oblique muscle using the fascia lata tendon expander technique. methods: a total of 12 patients with bilateral overaction of the superior oblique muscle and a-pattern strabismus were treated with bilateral superior oblique lengthening with fascia lata according to the values recommended by wright. fascia lata was harvested through a lineal incision on the lateral aspect of the patients' thigh. results: the follow-up was 4 to 51 months (mean, 28.8 ± 20.7 months). mean superior oblique overaction improved from 3.5 ± 0.8 before surgery to 0.8 ± 0.9 after surgery (p<0.001). mean a-pattern improved from 26.4 ± 8.5 pd to 1.7 ± 7 pd (p<0.001), and subjective intorsion improved from 6 ± 0.7 degree to 0.3 ± 1.1 degree (p<0.001). one patient developed overcorrection. none of the patients developed recurrence. conclusion: the fascia lata tendon spacer is a useful procedure in the treatment of a-pattern strabismus due to superior oblique overaction. this technique may be superior to posterior tenectomy because of less incidence of superior oblique overaction recurrence; however, the operation time is longer.

متن کاملSuperior oblique tendon expansion in the management of superior oblique dysfunction.
Traditional superior oblique weakening procedures may be unpredictable and lead to superior oblique underaction. The use of 240 retinal band as a spacer to lengthen the superior oblique tendon has been proposed as a more controlled approach than superior oblique tenotomy and related procedures. The use of this technique is reported in a patient with diplopia following an orbital floor blow out ...
متن کاملSuperior oblique tendon lengthening for acquired superior oblique overactions.
Two patients who presented with compensatory head postures and diplopia are described. They both had marked unilateral superior oblique overaction, in one patient due to a large, incomitant skew deviation. Each underwent a superior oblique tendon lengthening procedure using a segment of silicone 240 retinal band as an expander, in combination with a contralateral superior rectus recession. Both...
