耳鼻咽喉科医师、肿瘤科医师以及外科医师们经常遇到颈部肿块的临床患者,由于颈部解剖复杂,虽然临床上表现为一个或数个肿块,但病变却大有差异,今将颈部肿块最多见的病变归纳如下。颈部三角分区的解剖将颈部划分为较小的三角单位,就能将比较复杂的解剖变得较为简单,今分述如下: 胸锁乳突肌把颈部分成前、后两大三角。颈前三角的边界是胸锁乳突肌前缘、颈正中线(从胸骨柄至下颌骨正中的联线)与下颌骨体部下缘;颈后三角的边界是胸锁乳突肌后缘、斜方肌 Otorhinolaryngologists, oncologists, and surgeons often encounter clinical patients with neck masses. Due to the complex anatomy of the neck, although clinically manifested as one or several masses, the lesions vary widely. The most common lesions are summarized below. The anatomy of the cervical triangulation divides the neck into smaller trigonometric units, which can make relatively complex anatomy easier. This is described as follows: The sternocleidomastoid muscle divides the neck into two major triangles, front and back. The border of the anterior cervical triangle is the anterior border of the sternocleidomastoid muscle, the midline of the neck (the midline from the sternal stem to the mandible) and the lower edge of the mandibular body; the border of the posterior triangle is the posterior border of the sternocleidomastoid muscle.
