ABSTRACT
Purpose: To explore straight incision technique in terms of efficacy for intraocular pressure (IOP) lowering by small-incision cataract surgery (SICS) trab versus modified 揻rown� incision with triangular scleral flap technique. Methods: This study was done at a tertiary health center. It included 44 eyes diagnosed with cataract and coexisting primary glaucoma that underwent SICS with trabeculectomy using modified 揻rown� incision with triangular scleral flap technique and straight incision in group A (n = 22) and B (n = 22), respectively. Postoperative evaluation was done at first postoperative day, then at the end of first week, third week, and 6 weeks; at the end of third month and finally at the end of sixth months. Data were entered and analyzed via Microsoft Excel sheet and SPSS software using Mann朩hitney U test for averages and Chi-square test for categorical values. Results: Mean preoperative IOP in groups A and B were 38.6 and 29.1 mm Hg respectively, by applanation tonometry. After 6-month follow-up, mean of difference in IOP (preoperative � postoperative) for group A was 20.8 � 8.3 mm Hg and that for group B was 17.2 � 13.5 mm Hg. Conclusion: Capacity of IOP reduction of both techniques was found to be comparable and did not show much difference up to the end of 6 months. Mastering technique of group A (modified 揻rown� incision with triangular scleral flap technique) requires more expertise; the simpler straight incision technique provided in group B may be effectively used by the novice and current era Ophthalmologists to combat glaucoma coexistant with cataract.
ABSTRACT
Purpose: To calculate the surgically induced astigmatism (SIA) in MSICS through a superiorly placed straight scleral incision closed with a single, central, perpendicular 10?0 polyamide suture and to document any suture?related complaints and complications. Methods: A retrospective, hospital?based study was carried out in 50 cases of uncomplicated senile cataract (>50 year) with nuclear sclerosis ? grade 4, 搘ith the rule� astigmatism who underwent MSICS through a superior, straight incision with a single, central, perpendicular 10?0 nylon suture. Patients with 揳gainst the rule� astigmatism, keratoconus, pre?existing corneal opacity, astigmatism >2D, distorted or oblique mires, and previous ocular surgeries and unwilling to participate were excluded. Results: The mean age of the patients was 64.81 + 2.824 years, with a male: female ratio of 1.38:1. The mean SIA at day 7, week 6, and 12 weeks was 0.539 + 0.118, 0.529 + 0.134, and 0.524 + 0.129, respectively. Only 6 patients (12%) complained of foreign body sensation. No patient developed any suture?related complications. Conclusion: SIA is significantly reduced in straight incision by applying a single, central, and perpendicular 10?0 polyamide suture, as compared to a straight incision without a suture.
ABSTRACT
Objective To evaluate the clinical effect of straight incision in the treatment of scapular neck and body fractures .Methods 62 cases with scapular neck and body fractures were randomly divided into the obser -vation group (30 cases) and control group (32 cases).The control group was given the traditional Judet approach operation,the observation group was given the straight incision operation .The general situation of operation ,fracture healing time ,clinical efficacy and postoperative complications were observed .The improvement of joint function after operation was evaluated .Results The operation incision ,operation time and intraoperative blood loss of the observa-tion group were significantly better than those of the control group (t=9.599,9.506,21.297,P<0.01).The fracture healing time between two groups had no statistically significant difference (t=0.922,P=0.35).The effective rate of fracture healing in the observation group was 93.3%,which was significantly higher than 71.9%of the control group (χ2 =4.885,P<0.05).The incidence rate of complication in observation group was 13.3%,which was lower than 37.5%in the control group(χ2 =4.723,P<0.05).The score of daily activities in observation group was better than the control group(t=3.761,P<0.01).Conclusion The straight incision operation is more minimally invasive in the treatment of scapular neck and body fractures compared with Judet approach ,and it has better prognosis .
ABSTRACT
Objective To evaluate the effect of surgical treatment of hypertensive intracerebral hemorrhage (HICH) through a straight incision and keyhole minimally invasive craniotomy. Methods According to the location of the hematoma revealed by preoperative CT scans, a straight skin incision was made 4～5 cm in length, and then a keyhole craniotomy 2 cm in diameter was performed. The underlying cortex was incised the hematoma was exposed and removed under microscope. Results The hematomas were thoroughly cleared in 17 cases. The clearance rate was 90% in 18 cases and 80% in 4 cases. Re-hemorrhage occurred in 2 cases after operation. A total of 35 cases was followed for 0.5～3 years (mean, 2.1 years). The quality of life was assessed by activity of daily living (ADL) classification, which revealed 9 cases of grade 1, 12 cases of grade 2, 9 cases of grade 3, 4 cases of grade 4, and 1 case of grade 5 at the 6th postoperative month. The mortality of this series was 10.3% (4/39). Conclusions Straight incision keyhole minimally invasive craniotomy is a rapid, effective, and safe technique for the removal of hypertensive cerebral hemorrhage. The method herein provides an effective decompression of hematoma, with low recurrence rate and good prognosis compared with conventional surgery.
ABSTRACT
PURPOSE: This investigation was performed to evaluate the surgically induced astigmatism of no-stitch frown incision with 4.0 mm chord length, which was compared with no-stitch 3.2 mm straight incision. METHODS: Sixty eyes, which could be observed for 3 months, were divided into two groups. Both groups were composed of 30 eyes. Group 1 - a semicircular frown incision with 4.0 mm chord length was made 1 mm posterior and most convex to limbus. Group 2 - a 3.2 mm straight incision was made 2 mm posterior to limbus. No-stitch was done in both groups. The corneal astigmatism was evaluated at postoperative 1st day, 1st week, 2nd week, 1st month, 2nd month and 3rd month with Bausch & Lomb keratometry, calculated by values derived from Cravy's vector method and statistically analyzed by Student t-test. RESULTS: The change of surgically induced astigmatism in group 1 was 0.52 D, 0.45 D, 0.43 D, 0.38 D, 0.40 D, and 0.39 D at 1st day, 1st week, 2nd week, 1st month, 2nd month, and 3rd month, respectively. In group 2, it was 0.83 D, 0.72 D, 0.65 D, 0.52 D, 0.50 D, and 0.49 D at the same intervals. These differences of astigmatic change were not statistically significant(p>0.05). CONCLUSION: The astigmatic change in a no-stitch frown incision with 4.0 mm chord length was not enough to comparable with that of a no-stitch 3.2 mm straight incision. We could safely use PMMA intraocular lens by no-stitch frown incision. So, this method has some advantages over small incision with foldable intraocular lens.
