Clinical study on endoscope-assisted repair of zygomatic arch fracture / 华西口腔医学杂志

<p><b>OBJECTIVE</b>A study was conducted to investigate the relevant applied technique and clinical value of endoscope-assisted repair of zygomatic arch fracture.</p><p><b>METHODS</b>A 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.</p><p><b>RESULTS</b>Symmetric 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.</p><p><b>CONCLUSION</b>Endoscope-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.</p>

Clinical application of transconjunctival approach to treat orbitozygomatic complex fractures / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the effective of transconjunctival approach in treating orbitozygomatic complex fractures.</p><p><b>METHODS</b>Fifty-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.</p><p><b>RESULTS</b>The 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.</p><p><b>CONCLUSION</b>The 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.</p>

Reconstruction of maxillary defect with vascularized bone graft and internal fixation of titanium plate / 中华医学美学美容杂志

Objective To study clinical effect of transplantation with vascularized ilium bone and free fibulae, and internal fixation of titanium plate on reconstruction of maxillary defect. Methods Nine cases of maxillary defect were repaired by 7 iliac muscle flaps with deep circumflex iliac artery and vein, 2 cases of fibulae muscle flap with peroneal artery and vein, meanwhile, fixed internally by titanium plate. The vessels were anastomosed with arteria and vena maxillaries externa. Results Nine patients were confirmed by 99m TcMDP 2-4 weeks after operation that the supply of blood was well and the graft bones were survival. By follow-up from 6 months to 3 years after operation, the fixations of graft bones were good. Conclusion Vascularized bone graft and internal fixation of titanium plate is one of the best ways for reconstruction of maxillary defect.
