Objectives: To evaluate the surgical treatments and results of the patients with superior oblique muscle palsy (SOMP).\udMaterials and Methods: Clinical charts of the patients with unilateral SOMP who were operated in our clinic between 1999 and\ud2009 were evaluated retrospectively. Patients’ demographics, preoperative signs, surgical procedure, complications, and final results\udwere recorded.\udResults: Thirty-seven patients were included in the study, [21 (59%) male, 15 (41%) female]. The mean age was 20.6 years at the\udtime of operation. The mean time interval between diagnosis and operation was 7.3 years. Postoperative follow-up period was 2.04\ud(ranging 1-10) years. Diplopia was determined in seven (18.9%) patients, and abnormal head position in 36 (97.3%) patients. Only\udinferior oblique tenotomy with distal muscle resection was performed in 25 patients. In addition, five patients had recession of the\udcontralateral inferior rectus muscle and two patients had recession of the ipsilateral superior rectus muscle additional to inferior oblique\udtenotomy. Abnormal head position was completely improved in all of the patients postoperatively. The preoperative average score of the\udinferior oblique muscle (IOM) overaction was +3.3±0.8, and postoperative overaction was found in only two patients (+1.5). There was\udstatistically significant difference between the two periods (p<0.001). The average score of the superior oblique muscle hypofunction\udwas -2.18 preoperatively, and in only three patients, the score was found -1.0 postoperatively. Difference between the two periods was\udstatistically significant (p<0.001). While the preoperative average vertical deviation was 22 PD in primary position, none of the patients\udhad hyperdeviation postoperatively. Diplopia was resolved in all seven affected patients postoperatively. Contralateral IOM hyperfunction\udwas the most common complication (13.5%). Adherence syndrome was seen in none of the patients.\udConclusion: It was found that to weaken the IOM solely was satisfactory in the patients with hyperdeviation secondary to unilateral\udSOMP in this study.
