Analysis of the effect of repair materials for orbital blowout fracture on complications

引用

International Journal of Ophthalmology(English edition) 2019年第11期12卷 1746-1750页

作者： Qi-hua Xu Jin-Hai Yu yao-hua wang An-An wang Hong-Fei Liao Department of Ocular Trauma Orbital DiseaseAffiliated Eye Hospital of Nanchang UniversityNanchang 330006Jiangxi ProvinceChina Jiangxi Research Institute of Ophthalmology&Visual Sciences Nanchang 330006Jiangxi ProvinceChina

AIM: To investigate the effect of repair materials for orbital blowout fractures on the occurrence of postoperative complications. METHODS: The clinical data and follow-up data of 54 subjects with orbital blowout fractures were retrospectively analyzed. The study was divided into three groups according to the used repair materials: titanium mesh(16 cases), Medpor(12 cases), and Medpor titanium mesh(26 cases). All test data were analyzed using the SPSS version 23.0 statistical software. The mean age and duration of disease between the groups were compared through oneway analysis of variance. The Chi-square(χ~2) test was used to compare the number of males and females, different fracture types, and different surgical approaches among groups. The χ~2 test was used to compare the frequencies for complications in each ***: The baseline characteristics of age and gender in each group were matched(F=1.763, P=0.172;χ~2=0.026, P=0.987). In addition, there was no difference in the type of fracture and surgical approach(χ~2=0.460, P=0.977;χ~2=0.691, P=0.952), or the incidence of complications(χ~2=0.081, P=0.960) between the three groups. CONCLUSION: Although there is no difference in effect of various repair materials on the incidence of complications, the effect of repair materials on postoperative complications of orbital blowout fractures should not be ignored.

AIM: To evaluate the outcome of endoscopic dacryocystorhinostomy(En-DCR) with mucosal anastomosis in chronic dacryocystitis patients, with various categories of ethmoid ***: Between July 2015 and September 2019, 1439 adult patients, representing 1623 affected eyes, presented with chronic dacryocystitis and were scheduled for En-DCR. The categories of ethmoid sinuses were preoperatively determined, using computed tomographydacr yocystography(CT-DCG), and were classified as category 1(C1), category 2(C2), and category 3(C3). No sinuses anterior to the posterior lacrimal crest defined as C1. Sinuses found between the anterior edge of the lacrimal bone and the posterior lacrimal crest defined as C2. Sinuses found anterior to the lacrimal bone suture defined as C3. At the end of surgery, the dacryocyst and nasal mucosa were anastomosed in C1, and the dacryocyst mucosa and anterior ethmoid sinus were anastomosed in C2 and C3 ethmoid sinus patients. The surgical success rate and related complications, in patients with 3 categories of ethmoid cells, were monitored and ***: Postoperative data was obtained for 179 C1 affected eyes, 878 C2 affected eyes, and 432 C3 affected eyes. The overall success rate of En-DCR was 93.0%(1385/1489). Additionally, the success rates were comparable among the different ethmoid categories at 12mo post operation. We demonstrated that the major reason for surgical failure was intranasal ostial closure, due to granulation or scar ***: En-DCR is a feasible and highly effective primary treatment for chronic dacryocystitis. To ensure surgical success, the surgery protocol must be designed in accordance with the category of ethmoid sinuses present in individual patient.
