As patients pursue surgical interventions abroad, concerns about the elevated complication rates in AMT have emerged.

The study included 3367 patients, of whom 26% were international patients. Sociodemographic and clinical variables, flight details, and surgical complications were analyzed. Statistical analyses involved descriptive statistics, odds ratios, and multiple regression analyses.</p><p><strong>Results: </strong>Of the 865 AMT patients, 75 exhibited complications. Infection and wound dehiscence were the most prevalent; no severe complications or mortality was reported. The study revealed that AMT patients have a higher risk of complications compared to those locally treated (adjusted odds ratio = 4.6; 95% confidence interval = 2.6-8.2). Flight time exceeding 4 h was a factor associated with nonaesthetic complications.</p><p><strong>Discussion: </strong>This study reveals that AMT is linked to a higher risk of nonaesthetic complications, with flight duration being a significant contributing factor. Despite the increased risk, complication rates for AMT patients did not surpass thresholds reported in the literature; this may be attributed to the safety protocols implemented.
