A utilização de um dispositivo para a localização e padronização de imagens ultrassonográficas do coxim adiposo bucal no planejamento cirúrgico de bichectomia

Abstract

Objective: To locate the Buccal Fat Pad using the UStransfer device for anatomical study and the development of an ultrasonic mapping protocol to assist in the surgical planning of Bichectomy. Methodology: Sixteen patients of both genders, with no prior aesthetic procedures and with the presence of the Buccal Fat Pad, were evaluated. The UStransfer device was used to locate and demarcate the study area, which was subsequently analyzed by ultrasonography (Siemens ACUSON S3000™, HELX™ ultrasound model) on both the right and left sides, using a linear dermatological transducer (Siemens 18L6 HD with a frequency of 6.0 MHz - 18.0 MHz) positioned transversely and longitudinally. Volume measurements were taken at two different times, with a 15-day interval, by the same operator. Additionally, the accuracy rate in identifying the anatomical structure, a descriptive analysis of the volume measurements, and the intraclass correlation (evaluator) were assessed. The BioEstat 5.2 software was used for data analysis, followed by a literature review to deepen the study on the topic. Results: The Buccal Fat Pad was identified in 100% of patients, on both sides and at both time points. The intraclass correlation demonstrated excellent replicability (p<0.0001). There was no significant variation in the volume measurements between the two moments, both on the right side (standard deviation time 1: 0.39; time 2: 0.39) and on the left side (standard deviation time 1: 0.32; time 2: 0.29). An ultrasonic protocol for the Buccal Fat Pad was established to aid in the surgical planning of Bichectomy, using the UStransfer device as a localization method. Conclusion: The mapping using the UStransfer device facilitated the identification of Buccal Fat Pad in ultrasonography, providing an alternative that offers greater safety for the professional performing the surgical intervention and more efficiency for the radiologist in conducting the ultrasound examination.
