title: Unilateral zygomatic hypoplasia correction by L-shaped zygomatic osteotomy with natural coral.
abstract: OBJECTIVE
  Zygomatic osteotomy is a common method of zygomatic hypoplasia correction. Natural coral is considered to be a good bone substitute. Few studies on unilateral zygomatic hypoplasia correction by zygomatic osteotomy with natural coral have been reported. This study was performed to evaluate the clinical morphological results and surgical outcomes of unilateral zygomatic hypoplasia correction by L-shaped zygomatic osteotomy with natural coral.
  
  
  METHODS
  From 1996 to 2012, a total of 42 patients with hypoplastic zygomas treated by L-shaped zygomatic osteotomy with natural coral were included in this study. Based on facial analysis results and x-ray and CT measurements, the degradation of natural coral, new bone formation, and clinical outcomes were observed and recorded.
  
  
  RESULTS
  All surgical procedures achieved satisfactory results without complications. During the stabilization period of about 12 to 15 months, all natural coral blocks were completely degraded and replaced by new bone. Good mechanical strength and continuity of the new bone and good zygomatic asymmetry were achieved in each patient. No recurrence was observed during the follow-up period.
  
  
  CONCLUSIONS
  L-shaped zygomatic osteotomy with natural coral is an effective method of unilateral zygomatic hypoplasia correction.
