Abstract

Benign enlargement of the parotid gland hypertrophy results in a bulky lateral facial contour and esthetic appearance. This study aimed to determine the depth from the skin surface to the parotid fascia, which encompasses the parotid gland. The anatomical properties of the parotid glands were evaluated in 40 patients using ultrasonography. An up-to-date understanding of the localization of botulinum neurotoxin (BoNT) injection based on anatomy could lead to better localization of the injection into the parotid gland through morphological measurements using data previously published from cadaveric studies. Measurement using the otobasion inferius as a landmark revealed parotideomasseteric fascia thickness averaging 4-6 mm from the skin surface, with the parotid gland extending approximately 15 mm anteriorly. Analysis showed a 3-7 mm thickness range, indicating an optimal injection depth for safety and efficacy in BoNT procedures. Utilizing the otobasion inferius as an anatomical landmark offers a practical approach for measuring parotideomasseteric fascia thickness, addressing cadaveric study limitations. These guidelines aim to maximize the effects of BoNT therapy, which can be useful in clinical settings, by minimizing its deleterious effects.

腮腺注射肉毒杆菌神经毒素的超声研究和解剖学指南。
腮腺肥大的良性增生会导致面部侧面轮廓臃肿,影响美观。本研究旨在确定从皮肤表面到包裹腮腺的腮腺筋膜的深度。研究人员使用超声波造影术对 40 名患者的腮腺解剖特性进行了评估。根据解剖学对肉毒杆菌神经毒素(BoNT)注射定位的最新理解,可以通过使用以前发表的尸体研究数据进行形态测量,从而更好地确定腮腺的注射定位。以腮腺下缘为地标进行的测量显示,腮腺肌筋膜厚度平均为距皮肤表面 4-6 毫米,腮腺向前方延伸约 15 毫米。分析显示厚度范围为 3-7 毫米,这表明注射深度是 BoNT 手术安全性和有效性的最佳选择。利用腮腺下缘作为解剖标志为测量腮腺肌筋膜厚度提供了一种实用的方法,解决了尸体研究的局限性。这些指南旨在最大限度地提高 BoNT 疗法的效果,将其有害影响降至最低,从而使其在临床环境中发挥作用。
