The result of disinsertion(Tenotomy)+Distal myectomy at cases that primary inferior oblique overaction

There are several surgey thecniques of weakness primary or secondary inferior oblique overaction treatment. The most surgery thecniques are tenotomy, myotomy, ressesion, anterior transposition, and denervation-extirpation. Surgers choose one of these thecniques about effectiveness, easily perform and about complication.We observed disinsertion(tenotomy)+10 mm distal myectomy. Disinsertion (tenotomy) and 10 mm distal myectomy 45 eyes of 28 patients who were observed primary inferior oblique overaction. However, 22 patients who had primary inferior oblique overaction and horizantally strabismus we observed disinsertion(tenotomy) and 10 mm distal myectomy and horizantally strabismus surgery.The mean follow up time was 12.64+/-5.173 months(6-24 months)and during follow up time 40 eyes of 45 eyes(%88,8) perfect correction was gained and it was corelated with our succesful criteria. Seven eyes of 5 patients(%11,1) we observed residual inferior oblique overaction contrlaterale inferior oblique overaction was seen at 3th and 6th month folow up visit at 2 of 11 (%18) patients who undergone unilaterale surgery. inferior oblique hypofunction or asdherence syndrome was not seen at any patients.We believe that disinsertion(tenotomy) and 10 mm distal myectomy are effectiveness and safety surgery methods at primary inferior oblique overaction.
