Coronal incision for treating zygomatic complex fractures.

OBJECTIVES: To study the value of coronal incisions for treating zygomatic complex fractures. PATIENTS AND METHODS: A retrospective study was conducted on 69 out of 83 patients regarding the indications and complications of scalp incisions for treating zygomatic complex fractures (the other 14 patients were treated by local incisions and approaches). RESULTS: In the early postoperative period, 5 patients suffered from haemorrhage, 2 had infections, 24 patients reported immediate postoperative anaesthesia and paraesthesia affecting the supraorbital region. Six had symptoms and signs of facial nerve injury: difficulty with wrinkling the forehead or to closing the eyes. After a follow-up of 3-5 years, 6 cases suffered from a scar wider than 0.5 cm, paraesthesia in 2 cases (parietal region and temporal region), depression of the temporal fossa in 2 and 1 patient had (persistent) palsy of the temporal branch of the facial nerve. CONCLUSION: On one hand, coronal incisions offer advantages such as: extensive exposure to ensure exact anatomical reduction. On the other hand, this incision has disadvantages such as obvious scars, long operating time, infections, haemorrhage, paraesthesia in the operative region, palsy of the facial nerve and depression of the temporal fossa. Therefore, the indications for coronal incisions should be strictly applied, and this incision should not be overused.

[Function of disk reposition in the treatment of traumatogenic temporomandibular joint ankylosis].

OBJECTIVE: To investigate the method and results of disk reposition in the treatment of traumatogenic TMJ ankylosis. METHODS: In 19 cases of traumatogenic ankylosis of TMJ, the dislocated disks were repositioned during anthroplasty. In the operation, the dissection of dislocated disk was performed carefully around the TMJ. The disk was repositioned to its anatomic location over the top of condylar stump, then the lateral aspect of the disk was sutured to the soft tissue of zygomatic root. RESULTS: At the last follow-up examination, interincisal opening distance ranged from 24 to 43 mm in all cases (mean 32.63 mm), which approached or reached the normal level. No recurrence and TMJ symptom were found during the period of follow-up. CONCLUSIONS: The disk repositioning in treatment of traumatogenic TMJ ankylosis is a feasible and effective approach to reconstruct the structure and function and prevent recurrence.

[A clinical investigation on the surgical approach and fixation in operative treatment zygomatic fractures].

OBJECTIVE: To investigate the effect of soft tissue incision and rigid internal fixation in the treatment of zygomatic fracture. METHODS: 70 cases with zygomatic fracture were entered into the study. The clinical data of 65 patients who were performed operations in the treatment were analyzed. The study focused on the incision, number and locations of Titanium plate. The facial contour, reduction,fixation, healing of incision, facial bisymmetry and complications of the operation were followed up 3 - 24 months after surgery. RESULTS: All the incisions were primary healing. Clinical and radiologic assessment of reduction was symmetric and stable in 91.5% of all cases, asymmetric in 8.5% of all cases. Subcutaneous hematoma happened in 5 cases, Ti plate exposure 1 in case, scalp scar width was more than 0.5 cm in 6 cases, frontal part or scalp paresthesia 8 cases. CONCLUSIONS: Coronal scalp incision has advantages such as good exposure, precise removal of the bone block and good symmetry of both sides. RIF can improve the stability of fracture, promotes fracture healing and guarantees the rehabilitation of zygomatic complex. direct reduction and rigid internal fixation with Titanium microplate or miniplate are satisfactory in zygomatic fracture.
