Astigmatic Changes in Sutureless Small Incision Cataract Surgery

Introduction: Cataract is the main cause of bilateral blindness in Nepal. Surgery is the accepted treatment option for cataract with Small incision Cataract Surgery (SICS) and Phacoemusification being the common procedures being performed with comparable results. Corneal astigmatism has been a byproduct of cataract surgery since the first limbal incision was made with improved techniques. Self-sealing scleral pocket incisions are stable and provides early healing, faster visual restoration and more importantly superior astigmatism control. A variety of scleral incisions are being used in manual SICS, with the aim of keeping the post-operative astigmatism to a minimum. Despite having many techniques of scleral incision, there have been only few studies which compares surgical induced astigmatism (SIA) between them Objective: To determine surgical induced astigmatism following frown, chevron and straight incision forms in suture-less small incision cataract surgery(SICS). Methodology: A prospective study was done on a total of 120 patients aged 40years and above with senile cataract. The patients were randomly divided into three groups where each group received specific incision- Straight, Frown and Chevron. SICS with intraocular lens (IOL) implantation was performed. The patients were compared on 2 weeks and 6 weeks post operatively for uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) and keratometric reading. Surgical induced astigmatism (SIA) was calculated using the SIA calculator version 2.0. The study was analysed using SPSS version 20.0. Results: At 6 weeks UCVA of 6/18-6/6 was attained by 63.41%, 78.94% and 84.61% of patients in group straight, frown and chevron. However about 97% of patients attained BCVA of 6/18-6/6 in all three groups. Mean SIA was least in Chevron group (0.30 D ± 0.16) and was most in the straight group (1.22 D ±0.36) which was statistically significant. Conclusion: Chevron incision induces the least astigmatism compared to frown and straight incision.

COMPARISON OF POST OPERATIVE CORNEALASTIGMATISM FOLLOWING FROWN VERSUS CHEVRON INCISION IN MANUAL SMALL INCISION CATARACT SURGERY

Introduction: To study the comparison of post operative corneal astigmatism following frown versus chevron incision in manual small incison in manual small incision cataract surgery. Material and Methods:The study was conducted at govt. medical college jammu over a period of one year. The study includes a total of 100 pts. With age related cataract and were divided into two groups of 50 each. Detailed ocular examination of the cases with calculation of preoperative astigmatism were carried out in eye OPD. Results: st rd th th st All cases were assessed postoperatively at 1 , 3 , 6 and 12 week for surgical induced astigmatism .At the end of 1 week surgical induced astigmatism of more than 1D was seen in 72% pts. of group 1 with frown incision as compared to 48 % in group 2 with chevron incision. At the end of 12 weeks 54% of cases in group 1 with frown incision and only 8% in group 2 with chevron incision had astigmatism of more than 1 D. The difference between the two groups was statistically signicant. Conclusion: It is possible to reduce the amount of postoperative astigmatism signicantly by choosing the incision shape .Surgical induced astigmatism is less seen in patients with chevron incision as compared to patients with frown incision.

Midline Incision versus Chevron Incision in Open Radical Nephrectomy: Quality of Life Differences

Objective: Open radical nephrectomy can be performed through midline or chevron incision. This study aims to compare the quality of life between midline and chevron incision in open radical the nephrectomy since comparison studies between these approach focused on quality life are still lacking. Methods: This study includes total 31 patients that underwent open radical nephrectomy in Cipto Mangunkusumo Hospital Indonesia. The subjects were divided into midline and chevron groups using simple random sampling. Modified WHOQOL BREF and VAS pain score were compared between these groups. Results: Total 31 subjects included, with a male: female ratio 2.33:1 and age mean 49.81±13.1 with the incidence are highest at 41-60 years old. In our study, most subjects were diagnosed in T3-T4 with 58,07% overall. Clear cell renal cell carcinoma is the most frequent pathology result with 41,93% followed by Paper Renal cell Carcinoma 12.90%. VAS score is higher in Chevron group with result 2,47±1,40 compare to Midline group with 2,13±1,99. Match to the VAS score result, The Modified WHOQOL BREF Chevron group with mean 71,80±10,24 is lower than Midline group with 77,69±13,65. However, these differences are not statistically significant. The midline group was recorded two complications (IVC and spleen injury), whereas one complication (IVC injury) recorded in chevron group. Conclusion: Both chevron and the midline are safe methods for open nephrectomy. Even the midline incision show better VAS score and quality of life, and there are no significant differences between midline or chevron incision in postoperative quality of life, VAS scores and intraoperative bleeding.

Dorsal Approach Rhinoplasty

ABSTRACT Direct dorsal excision of skin and subcutaneous tissue is employed in rhinoplasty cases characterized by thick rigid skin to achieve satisfactory esthetic results, in which attempted repair by more conventional means would most likely frustrate both surgeon and patient. This historical review reminds us of the lesson: ‘History repeats itself.’ Built on a foundation of reconstructive rhinoplasty, modern cosmetic and corrective rhinoplasty have seen the parallel development of both open and closed techniques as ‘new’ methods are introduced and reintroduced again. It is from the perspective of constant evolution in the art of rhinoplasty surgery that the author presents, in Part II, his unique ‘eagle wing’ chevron incision technique of dorsal approach rhinoplasty, to overcome the problems posed by the rigid skin nose.

Surgical treatment of big splenic artery aneurysm: Case report

An aneurysm has been defined as a permanent local dilatation of the diameter of an artery by at least 50% of its normal value. A splenic artery aneurysm is most frequently a visceral artery aneurysm and clinically it is usually asymptomatic but potentially life-threatening at the same time, with the incidence of its rupturing being 2-10% and then the mortality rate ranges from 20 to 36%. A 51-year-old female patient was admitted to the Department of Vascular and Transplantation Surgery in Novi Sad having been found to have a big splenic artery aneurysm during the ultrasound examination of her abdomen after cholecystectomy. The additional diagnostic procedure - computerized tomography of the abdomen with i.v contrast subtraction angiography-confirmed the splenic artery aneurysm to have the diameter of 5 cm and therefore the elective surgical treatment was indicated after the preoperative preparation and risk assessment. The aneurysm was exposed through Chevron incision, and the detailed surgical exploration was done after the omental bursa had been opened. The aneurysmectomy and the reconstruction of the splenic artery by the termino-terminal anastomosis were performed after the weakening of the wall had been verified. The biopsies of the liver and the aneurysmal sac were done during the surgery. The pathohistological finding confirmed the atherosclerotic etiology of the aneurysm. Since the postoperative course was normal, the patient was discharged on the eighth postoperative day.
