OBJECTIVEA study was conducted to investigate the relevant applied technique and clinical value of endoscope-assisted repair of zygomatic arch fracture.

METHODSA total of 10 cases of unilateral zygomatic arch fracture and 8 cases ofunilateral zygomatic fracture were included. Reduction and fixation of the zygomatic arch in all cases were performed via asmall face incision by an endoscope. Endoscope-assisted repair allowed exposure of zygomatic arch fracture and ended the anatomy of the reset. Zygomatic arch was stabilized with titanium plates.

RESULTSSymmetric malar was achieved in allcases after operation. Patients did not show difficulty in opening the mouth. No chewing problems or severe complicationswere evident. This method had the advantage of hidden incision, and it did not leave scars on the face. Postoperative CT examination showed excellent reduction of zygomatic arch fracture and good fixed position of titanium plate.

CONCLUSIONEndoscope-assisted repair of zygomatic arch fracture via a small face incision can be an alternative operation for zygomaticarch fracture. Patients are less traumatized. There are fewer complications. A good reduction of fracture is achieved.

OBJECTIVETo evaluate the effective of transconjunctival approach in treating orbitozygomatic complex fractures.

METHODSFifty-four transconjunctival incisions were applied to correct enophthalmos and face collapse in 46 patients who suffered by orbitozygomatic complex fractures. All operative procedures were performed with an additional lateral canthotomy (5-10 mm) and 43 of them with gingivobuccal sulcus incisions simultaneously. The infraorbital rim and lateral orbital wall were stabilized with titanium plates. Titanium nets were used to reconstruct the comminuted orbit floor fractures.

RESULTSThe bilateral zygomaticas of 46 cases with orbitozygomatic complex fractures were basically symmetric, and the eyeball positions were reset anatomically. The treatment effectiveness were satisfactory. There were no obvious postoperative complications, except one corneal epithelium stripped on the right side and one overtime swelling of conjunctiva which cured after relevant treatments.

CONCLUSIONThe transconjunctival approach has good exposure to the orbital floor without visible scar and injury to facial nerve branches, it is a preferable procedure to reconstruct orbitozygomatic fractures.

Objective:To establish the "1+3" management module of high-value consumables in Operation Room and verify its application, so as to provide new ideas for cost management of consumables in Operation Room.Methods:The Operating Room team of Shenzhen Hospital of Southern Medical University designed a "1+3" management module in 2022, where "1" referred to the management process of high-value consumables in Operation Room, and "3" referred to the precise management of consumables in Operation Room warehouse, the management of closed-loop use of Operation Room consumables and adverse event management of consumables. Surgeries using high-value consumables in the Thoracic Surgery Department, Gastrointestinal Surgery Department, and Urology Department of the hospital were selected as the research objects. The surgeries using conventional consumables from January to June 2022 were set as the control group, and the surgeries implementing the "1+3" management module from July to December 2022 were set as the observation group. The number of consumables received by the itinerant nurses before the operation and the number of high-value consumables returned after the operation were compared between the two groups. And the number of missed and error charges for high-value consumables in the two groups were counted and compared.Results:The number of consumables received before operation in the control group was higher than that in the observation group, and the difference was statistically significant ( P<0.05). The number of high-value consumables returned in the observation group was less than that in the control group, and the difference was statistically significant ( P<0.01). The proportion of missed charges for consumables in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.01), but there was no statistically significant difference in the proportion of incorrect charges between the two groups ( P>0.05) . Conclusions:The "1+3" management module for high-value consumables in Operation Room makes the process of receiving, returning, and charging high-value consumables clear, with traceable data, achieving refined management of high-value consumables in Operation Room, reducing the number of high-value consumables returned to the warehouse and reducing the proportion of missed consumables, which is conducive to effective cost control in Operation Room.
