目的探讨住院医师初学斜视手术时,结膜切口和直肌处理方法对术后并发症及眼位矫正成功率的影响。方法回顾性分析103例斜视手术的切口方式、直肌处理方法与术后并发症及眼位矫正成功率的关系。结果共同性斜视手术103例,采用传统梯形切口,直肌缝合于肌止端后巩膜处45例;穹窿结膜切口,直肌悬吊后徙术58例。两种手术方式最终术后斜视角<10△,欠矫和过矫者无明显差异(χ2=4.672,P>0.05)。传统切口及手术方式组2例行二次手术调整眼位。穹窿结膜切口术后瘢痕小,结膜愈合平整,眼部刺激症状轻。结论穹窿结膜切口愈合美观,可调节后徙缝线法方便对术后眼位的调整,避免二次手术,但操作比传统切口略有难度。 相似文献

临床上对大角度外斜视多采用外直肌超常量后徙。但在手术实践中我们感到,在超常量后徙外直肌时,无论是角膜缘结膜梯形切口还是跨肌肉结膜切口,切口较长,结膜损伤多;同时,由于向眼球后方过多分离眼球筋膜、肌间膜,易造成广泛粘连,而且手术操作较困难。有文献报道采用外直肌悬吊后徙术矫治大角度外斜视效果满意,手术操作简便、易行。改良Parks切口则有手术操作简单,术后瘢痕细小、隐蔽、无碍美容等优点。为减少组织损伤,我们在2006年采用改良Parks结膜切口联合外直肌悬吊后徙矫正大角度外斜视20例,取得满意临床效果,现报告如下。 相似文献

Use of adjustable sutures: a helpful modification 总被引:3,自引:0,他引:3
Adjustable suture surgery helps achieve visual axis alignment in special cases. We describe a modification of adjustable suture surgery that provides better patient comfort and easier assessment of the muscle function at the time of adjustment. These beneficial features are achieved by using the cul-de-sac approach and by delaying final adjustment up to one week postoperatively. We review our experience involving 52 cases and discuss the surgical methods and reasoning behind delayed suture adjustment through the cul-de-sac approach. 相似文献

PURPOSE: To compare the postoperative results of adjustable-suture strabismus surgery when suture adjustment was performed 8 hours (group 1) and 24 hours (group 2) after surgery. METHODS: A retrospective clinical study was conducted in two hospitals. Strabismus surgery and muscle adjustment were performed in 90 patients. All patients had horizontal strabismus (40 patients had esotropia and 50 patients had exotropia), and they underwent either primary surgery or reoperation. Mean age of the patients was 29.9 +/- 14.1 (range, 14 to 74) years. The angle of deviation was measured in all patients before surgery, after surgery both before and after adjustment, and at the final follow-up examination. The follow-up period was 6 to 40 months (mean, 19.6 months). RESULTS: Preoperative data were similar in the two groups. The mean angle of deviation immediately after muscle adjustment was 0.6 +/- 6. 1 prism diopters in group 1 and 0.4 +/- 6.3 prism diopters in group 2. This similar deviation in the two groups (P =.9) changed during the follow-up period, and at the final examination the measured angles in groups 1 and 2 were -1.0 +/- 7.9 and -2.5 +/- 10.3 prism diopters, respectively (P =.48). The most considerable outcome measure was the calculated drift values. At the last follow-up these values were -1.6 +/- 5.8 for group 1 and -2.9 +/- 11 prism diopters for group 2 (P =.5). Subdividing the patients on the basis of their deviation before surgery, a postoperative drift toward exotropia was found in most patients of group 1. In group 2, however, a greater tendency toward exotropia was shown only by those patients who had displayed exotropia preoperatively, whereas patients with preoperative esotropia showed a greater tendency toward esotropia after surgery. CONCLUSION: In patients undergoing horizontal extraocular muscle surgery with adjustable sutures, suture adjustment 8 hours or 24 hours after surgery did not produce significantly different results. 相似文献

PURPOSE: The use of adjustable sutures in strabismus surgery has increased the rate of surgical success. Little data are available on the optimum timing for postoperative adjustment after strabismus surgery. We wanted to compare 2 common practices of adjustable suture technique after strabismus surgery. METHODS: Two comparable groups of 40 patients each, who had strabismus surgery with adjustable suture technique, were prospectively studied. Group A had early adjustment the same day of the surgery about 6 hours after the operation, and group B had late adjustment the next day about 24 hours after the operation. Subjective scoring tables were used to evaluate the pain felt by the patient before, during, and after the adjustment and any difficulties of the adjustment process. Requirements of postoperative pain medications and final alignment 6 weeks after surgery were also compared. RESULTS: Despite adequate statistical power, no significant differences were found between the groups regarding pain before, during, and after adjustment, difficulties performing the adjustment, and final alignment after 6 weeks (P > .05). Both adjustment schedules were equally associated with mild to moderate pain before, during, and after the adjustment. In the first 24 hours after surgery, no overall difference in the use of pain medications was found. Nausea and vomiting in the first 24 postoperative hours were more common in the early adjustment group (P = .02). CONCLUSION: The surgeon can feel free to choose the timing for postoperative adjustment. However, when performing an early adjustment, the surgeon should be especially prepared to control nausea and vomiting. 相似文献

Purpose:To evaluate the outcomes of large-angle exotropia by single-stage adjustable strabismus surgery (SSASS) under monitored conscious anesthesia.Methods:A prospective study was done in 33 patients above 14 years with ≥40 prism diopters (PD) of exotropia. All patients underwent SSASS under monitored conscious anesthesia (topical anesthesia plus intravenous sedation). For deviations of ≤55 PD, two horizontal rectus muscles, and for >55 PD, three rectus muscles were operated and a decision on adjustment/operating on an additional rectus muscle was taken after assessing the alignment. Monitored conscious anesthesia allowed us to check our results after surgery and plan further surgery/adjustment to achieve the desired alignment.Results:Mean preoperative deviation for distance was 52 ± 11.1 PD. The target alignment was achieved with the initial surgical plan in 10/21 patients with <55 PD exotropia and 4/12 patients with >55 PD exotropia, and one patient in each group needed adjustment. The remaining patients needed additional rectus muscle surgery. One patient with >55 PD exotropia needed both adjustment and additional rectus surgery. The success rate for distance correction was 85% at 6 months and 1 year. The overall success rate was 71% at 6 months. Percentage of patients with binocular single vision improved from 31% preoperatively to 78% by 6 months. Incidence of oculocardiac reflex was 6.1%.Conclusion:SSASS under monitored conscious anesthesia is a viable option for large-angle strabismus correction with good patient comfort and safety. 相似文献

BACKGROUND AND OBJECTIVE: This study was conducted to analyze the efficacy of the adjustable suture technique for correction of strabismus in patients with different types of strabismus. PATIENTS AND METHODS: This was an observational case series of patients who underwent the adjustable suture technique for correction of strabismus. A total of 33 adult patients (16 males and 17 females) with a minimum postoperative follow-up period of 6 months were included in the study. Patients were analyzed in three groups (patients with exotropia, esotropia, and vertical deviations). Success criteria determined were percentage change in the angle of deviation for far and near fixation, need for reoperation, and relief of diplopia. RESULTS: The median percentage change in the angle of deviation for far and near fixation was 86.60% and 84%, 92.50% and 94.44%, and 100% and 100% in the exotropia, esotropia, and vertical deviation groups, respectively. There was no need for reoperation, and postoperative adjustment performed 24 hours after surgery was needed in 30.3% of patients due to diplopia. CONCLUSIONS: The adjustable suture technique seems to be an effective method in the correction of various types of strabismus. 相似文献

Purpose
To compare the success rates and stabilities of postoperative alignment between adjustable and the non-adjustable surgeries in the treatment of sensory exotropia.Methods
A retrospective analysis was performed on all patients with sensory exotropia who had undergone unilateral lateral rectus recession and medial rectus resection (R&R) between January 1998 and August 2005. Thirty-four patients underwent conventional R&R, and 20 patients underwent R&R with adjustable suture of the lateral rectus. The surgical results between the two groups were analyzed with regard to the preoperative and post-operative deviation angles and the postoperative drift. The postoperative deviation angle was measured on postoperative day 1 as well as at two weeks, three months, six months and the final visit after surgery.Results
There were no statistically significant differences in the mean preoperative and postoperative deviation angles between the two groups. In 30 (88%) patients in the non-adjustable group and 15 (75%) patients in the adjustable group, postoperative deviation was less than 15 prism diopters (PD) at the three month follow-up. There was no significant difference in the mean postoperative drift between the two groups.Conclusions
Strabismus surgery with adjustable sutures did not show a significantly better result than surgery without adjustable sutures in the treatment of sensory exotropia. Considering the amount of postoperative exodrift in both groups, we postulate that the immediate ocular alignment after surgery for sensory exotropia should be orthophoric or 5-6 PD of esodeviation. 相似文献19.
PURPOSE: Immediate postoperative adjustment after adjustable-suture strabismus surgery has been suggested as a viable alternative to the classic adjustment that is performed, usually within 6 to 24 hours after surgery. The purpose of this study was to compare the immediate postoperative eye measurements with those taken 24 hours postoperatively and to determine whether there was any significant difference between the 2 measurements. METHODS: This was a prospective study of strabismus patients who were candidates for muscle surgery using the adjustable-suture technique. All patients received a total intravenous general anesthesia, which allowed rapid recovery of consciousness. Measurements using the simultaneous prism cover test were obtained in the recovery room immediately after the patients regained consciousness and again 24 hours after surgery. Both measurements were taken before adjustment and were compared. RESULTS: A total of 25 patients were studied. The postoperative alignment changed significantly during the first 24 hours in 84% of our patients. The mean drift in alignment during the first 24 hours measured 7.2 +/- 4.3 prism diopters and was significantly different from 0 ( P < 0.001). CONCLUSION: The immediate postoperative ocular alignment after adjustable strabismus surgery is significantly different from the 24 hours postoperative alignment. This difference was noticed despite using an anesthesia protocol that allowed rapid recovery and full regaining of consciousness shortly after the conclusion of surgery. This early drift should be taken into consideration if adjustment is to be made in the immediate postoperative period. 相似文献
