Background: With the technological advances, microsurgery has evolved to the era of supermicrosurgery since its inception. With the popularization of these flaps, proficiency in using tools such as color Doppler ultrasound (CDU) has become crucial. Despite the increased interest, studies regarding the role of ultrasound in microsurgical reconstruction are scarce. Therefore, in this study, we discussed currently available imaging modalities for reconstructive surgeons, types of ultrasound, and the role of ultrasound in microsurgical reconstruction, and made recommendations for ultrasound use in reconstructive surgery.
Methods: We performed a computerized search of ultrasound in reconstructive surgery using the MEDLINE database. Data regarding ultrasound indications, usage, and outcomes were collected.
Results: Of the 115 articles identified, the majority was written on nonreconstructive ultrasound uses (51.4%). For the reconstructive uses, mapping of perforators was the most common usage (39.1%), followed by flap monitoring and volume measurement. In addition, we found that there are a limited number of literature on the role of CDU in reconstructive surgery, especially on its intraoperative and postoperative use.
Conclusion: CDU is a valuable and powerful tool for any reconstructive surgeons who are interested in performing microsurgery or supermicrosurgery. As the demand of customized flaps using superthin flaps, perforator-to-perforator anastomosis, and supermicrosurgery increases, understanding and becoming versatile in CDU will be critical. We hope our experience with using ultrasound and refinements that we made are helpful for those who would like to include it as a part of their armamentarium.
