Orthognathic surgery involves manipulation of the jaws and skeletal structure to overcome inherited or acquired skeletal abnormalities. The psychological and social effect on these patients is recognized in many literatures. The aim of current study is to compare the quality of life in psychological, social and economic changes after orthognathic surgeries of single jaws vs. double jaws. Methods: A questioner was distributed to 40 patients in a recall visit that underwent orthognathic surgery from January 2015 to December 2017. The questioner included 27 questions divided into 7 sections out of which 3 questions related to demographic parameters such as age, gender and education level, 2 were about etiology of surgery, 3 were about orthognathic treatment plan, 12 questions were about facial changes reflecting psychological outcome of the surgery, 5 about social effect and 2 were about economical outcome of the surgery. Result: Total number of the patients in the current study was 40 out of which, 27 had a double jaw surgery while 13 had a single jaw surgery. The result was divided into four sections, including general information, physiological, social and economic section. The participant scored the highest percentage for improvement of beauty where double vs. single was 20 (64.5%) vs. 11 (35.5%). In regards to gummy smile improvement the participant reported 8 (29.6%) vs. 4 (30.8%) in double vs. single jaw. Lip fullness was significant in single jaw surgeries with P-value 0.015. Mandibular angle changes reported in 12 out of 27 (44.4%) in double jaw comparing to 1 out of 13 (7.7%) in single jaw with a significance of 0.029. In documenting post-op TMJ clicking, double jaw surgeries reported having 12 (44.4%) clicking while it was only 5 (38.5%) in single jaw where all patient did not experienced TMJ clicking pre surgery. Conclusion: Generally orthognathic surgery has a positive influence on the psychological, social and economic status of patients with jaw deformities. Unexpectedly there was no difference in between double and single jaw surgeries in psychological, social and economic status except in lip fullness and mandibular angle. In the current study patient with single jaw surgeries reported increases in lip foulness while double jaw surgeries reported significant increases in the mandibular angle improvement.
