Objective To assess the effect of surgical repair of medial orbital wall combined with orbital floor fracture via lower lid subciliary approach. Design Retrospective case series. Participants 18 cases of medial orbital wall combined with orbital floor fracture. Methods All patients underwent the reconstruction of orbital wall via lower lid subciliary approach. The composite hydroxyapatite was implanted into the surface of medial orbital wall and orbital floor after lacriminal cyst was completely dissected and protected during the operation. Orbital axial and coronal CT, three-dimension CT scan have been used in all the cases preoperalively and postoperatively. Preoperative CT was compared with postoperative CT. Main Outcome Measures Clinical symptoms and complications. Results All patients were followed up for 3 to 18 months. The postoperative scar of infracillary skin was not obvious. The composite hydroxyapatite was not rejected and dislocated in all cases postoperatively. No postoperative epiphora was found in either case. Preoperative diplopia and enophthalmos were corrected. Conclusion The treatment of medial orbital wall combined with orbital floor fracture via an isolated lower lid subciliary approach was feasible. But the incision was only used in the treatment of inferior medial orbital wall combined with orbital floor fracture, especially the transition area fracture between the orbital floor and medial orbital wall.

Background Orbital fracture in children has its own characteristics.Choosing the suitable plastic materials is the effective measurement to improve the successful rate of surgery.Absorbable plate filling provides a new material for children with orbital fracture.However,few studies compare the effectivity and safety between absorbable plate filling and conventional filling.Objective The aim of this study was to compare the longterm efficacy and safety between absorbable plate and Medpor implants in the repair of pediatric orbital fracture.Methods Clinical data of 72 eyes of 72 pediatric patients with orbital fracture who received surgicals reconstruction in Beijing Tongren Eye Center from 2008 April to 2014 August were respectively analyzed,including 28 patients with absorbable plates filling and 44 patients with Medpor implants.Demography and preoperative clinical signs were matched between the two groups.Operative procedure was same except the implanted materials.The functional training of extraocular muscle was performed since the second day after surgery in both groups.The imaging findings of the orbit were evaluated by computed tomography (CT) before and after surgery.The patients were followed-up for avarage 12.7 months after operation.The therapeutic effectiveness and safety were compared between the different implants,such as incidence of enophthalmos,extraocular movement impairment and diplopia,and the sensory deficit of skin and complications were documented.Results Extraocular muscle movement improved and diplopia alleviated or disappeared in 92.9％ (26/28) in the absorbable plate group and 90.9％ (40/44) in the Medporgroup,without significant difference between the two groups (P=0.57).The sensory deficit of skin was found in 13 eyes (46.4％) and 20 eyes (45.5％ in the absorbable plate group and Medpor group,respectively,and there was no significant difference between the two groups (P =0.56).CT revealed that the anatomical reconstruction of orbits could be achieved in all patients in both groups without the shifting of implants and extrusion.No enophthalmos and postoperative infection were found in absorbable plate group,however,the residual enophthalmos or late infection was found in I eye for each in the Medpor group.Conclusions Both the absorbable plate and Medpor implants show good results for reconstruction of pediatric orbital fracture.Absorbable plate is an ideal material for pediatric orbital blowout fracture because of fewer postoperative complications.

Objective:To explore the effect of nursing interventions based on systematic concept in elderly patients with type 2 diabetes.Methods:From May 2018 to August 2019, 120 elderly patients with type 2 diabetes in Hangzhou Red Cross Hospital were selected by convenience sampling. The patients were randomly divided into observation group and control group with 60 cases each. Patients in each group were given nursing interventions based on systematic concept and routine nursing respectively. The anxiety, depression, benefit finding and coping modes of the two groups were compared before and after the intervention.Results:Before the intervention, there was no statistical difference between the two groups in the scores of anxiety, depression, benefit finding and behavior pattern ( P>0.05) . After intervention, the scores of anxiety and depression in the two groups decreased, and the scores in the observation group were lower than those in the control group, with statistically significant differences ( P<0.05) . After the intervention, the scores of benefit finding of the two groups increased, and that of the observation group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . After intervention, the scores of confronting of the two groups increased, and that of observation group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . After intervention, the scores of avoidance and resignation in the two groups decreased, and the scores in the observation group were lower than those in the control group, with statistically significant differences ( P<0.05) .
