title: [CLINICAL STUDY ON ZYGOMATIC SPINDLE-SHAPED OSTEOTOMY AND INTERNAL PUSH OF TITANIUM SCREW ANCHOR IN TREATMENT OF PROMINENT MALAR].
abstract: OBJECTIVE
  To explore the effectiveness of the zygomatic spindle-shaped osteotomy and internal push of titanium screw anchor for prominent malar.
  
  
  METHODS
  Between July 2011 and January 2015, 58 patients with prominent malar underwent zygomatic spindle-shaped osteotomy and internal push of titanium screw anchor. There were 3 males and 55 females, aged 18-33 years (mean, 23 years). They had congenital bilateral prominent malar. Preoperative anteroposterior, lateral, supine position, 45" oblique photographs of the face were taken, three-dimensional CT reconstruction of face was performed. Simple prominent malar was observed in 30 cases, and prominent malar and zygomatic arch in 28 cases; zygomatic bone and zygomatic arch were symmetrical in 51 cases, and asymmetrical in 7 cases.
  
  
  RESULTS
  All patients obtained stage I incision healing after operation, without infection or hematoma. Numbness of the upper lip occurred in 2 cases, limitation of mouth opening in 1 case, and nasolabial fold deepening in 1 case, which recovered spontaneously after 3 months. Fifty-eight cases were followed up 6-12 months (mean, 10 months). Zygomatic narrow spacing was 10.6-13.9 mm (mean, 11.2 mm). No ptosis of facial soft tissue, zygomatic step, facial nerve injury, raising eyebrow, dysfunction of eyes closure, or temporomandibular joint disorder syndrome occurred. Good bone healing was obtained, zygomatic facial sensation had no obvious abnormality, all patients were satisfied with the improvement of appearance.
  
  
  CONCLUSIONS
  Zygomatic spindle-shaped osteotomy and internal push titanium screw anchor can effectively reduce the cheekbones, and maintain the natural curve of zygomatic body and zygomatic arch. Because of simple operation, less complications, and excellent results, it is an ideal plasty.
