Abstract:
Objective:The thickness of subcutaneous fat of the chest wall treated with vacuum bell can cover up the true depression in patients with pectus excavatum, when measured only from the body surface. The purpose of this study was to investigate the impact of this thickness of fat on treatment evaluation.Methods:Patients treated with vacuum bell from January to June 2022 in our center were retrospectively analyzed. The Haller index(HI), anterior chest wall fat thickness(A), lateral chest wall fat thickness(L), depth of body surface depression(SD), and depth of bone depression(BD) were measured by CT at the beginning of treatment and 1 year after treatment. The influence rate of vacuum bell was calculated by measuring the change of fat thickness before and after treatment to reflect the influence of vacuum bell on the growth of fat.Results:A total of 41 patients were enrolled, with a median age of 6.4 years old(1-14 years old). The mean HI before and after treatment was 3.6±0.7 and 3.2±0.5, and the Haller index of 10 cases was still aggravated after treatment, and the effective rate of real suction cup treatment was 75.6%. The subcutaneous fat of the anterior chest wall was thickened in 95.1%(39 cases) patients, and A before and after treatment was(4.0±1.9)mm and(7.5±3.2)mm respectively. The average influence rate of vacuum bell was 100%(33%-267%). The mean improvement of BD and SD before and after treatment was(1.7±3.9)mm and(4.0±3.3)mm respectively.Conclusion:The use of vacuum bell will thicken the fat of chest wall, and only evaluating by measuring the body surface will cover up the true depression. Compared to the lift of the sternum and ribs, the increase of the fat in depression area will give an additional improvement in appearance.
