The aim of this study was to find out the common complications after Septoplasty and Septorhinoplasty in a series of 127 Saudi patients undergoing Septoplasty or Septorhinoplasty in Northern Saudi Arabia. Methodology: This study included a series of 127 patients presented with nasal blockage and subsequently undergone Septoplasty and /or Septorhinoplasty. Results: Complications were determined in 69/127 (54.3%) of the patients. The most common complication after three months of septoplasty or Septorhinoplasty was the change in the shape of the nose, which represented 57 (82.6%) out of 69 patients with complications. Bleeding was experienced in 8 patients of whom 5/8 (62.5%) were males and 3/8 (37.5%) were females. Conclusion: Nose deformities are the most common complication associated with Septoplasty or Septorhinoplasty in Northern Saudi Arabia. The risks for Septoplasty or Septorhinoplasty complications can be condensed with accumulative experience.展开更多
