Comparison of the Prevalence of Body Dysmorphic Disorder in Rhinoplasty Patients and its Influence on its Surgical Outcomes.

Introduction: Body dysmorphic disorder (BDD) in the Diagnostic and Statistical Manual of Mental Disorders 5th Edition, is defined as one of pseudo-obsessive disorders; a class of obsessive-compulsive disorders. Whereas BDD has been weakly investigated among the Middle east population and there are little data about the prevalence of BDD in Iran especially in the northern part, in this study we tend to investigate the prevalence rate of BDD and its relationship with demographic factors and post-operative satisfaction in a sample of candidates for cosmetic and non-cosmetic surgery in Rasht. Method: During an analytical cross-sectional study, we investigated the prevalence of BDD in 100 applicants for cosmetic surgery (rhinoplasty) and 100 applicants for non-cosmetic surgery (including septoplasty and FESS) who were referred to Amir Al-Momenin Hospital in 2022. The modified Yale-Brown Obsessive Compulsive Questionnaire was used to examine BDD. Also, postoperative satisfaction (3 months later) was evaluated and compared in these two groups through telephone calls. SPSS software version 22, Fisher's test, chi-square test, independent t-test, and multiple logistic regression analysis were used for statistical analysis of the collected data. Results: The frequency of BDD in rhinoplasty applicants is significantly higher than the non-cosmetic surgery applicants (P-value = 0.005). The chance of BDD in rhinoplasty applicants is 4 times more than in non-cosmetic surgery applicants (P-value = 0.001, OR = 4.03). There is no significant difference in post-operative satisfaction between cosmetic and non-cosmetic surgery applicants (P-value = 0.975). Conclusion: It is recommended that all applicants for cosmetic surgeries be examined with appropriate tools in terms of mental health before being accepted by surgeons so that they can be referred to psychiatrists if needed and unnecessary cosmetic surgery should be avoided.
