| Popis: | Background:. Profound variations in facial nerve branching, combined with the severe impact of facial palsy on the patient’s quality of life, make surgery in this region challenging. Recent advancements in ultrasound (US) technology, including the improved visualization of small structures, have led to a sharp increase in its medical indications in various medical disciplines. We aimed to prove the feasibility of using ultra-high–frequency (UHF) US to visualize the facial nerve and to guide surgeons during surgery on and around the facial nerve. Methods:. A cadaveric study was performed on one hemi-face with a UHF US imaging system and state-of-the-art transducers. Firstly, a transcutaneous US was performed, and the facial nerve branches of interest (zygomatic, buccal, and marginal mandibular branches) were marked using US-guided color-injections of filler mixed with methylene blue. Skin and subcutaneous fat were then removed to simulate the intraoperative field. Secondly, an “intraoperative” US examination was performed, and the same branches were marked by US-guided color-injections of filler mixed with indocyanine green. Anterograde facial nerve dissection was performed, and the distance between the nerve branches and the injected filler was measured. Results:. All color-injections (mixed with both methylene blue and indocyanine green) were positioned right next to the nerve branches ( |
