The accessory submaxillary gland is a very uncommon anatomical variant, and incidence in the general population has not yet been quantified. The presence of pathology in these glands is rarer still, thus often going unnoticed.
We describe two accessory submaxillary gland cases, one asymptomatic and the other with chronic sialadenitis in the main and accessory gland caused by sialolithiasis. Although our diagnosis was by computerized tomography, magnetic resonance sialography is helpful to understand and describe this entity with greater precision.
The first case report is an incidental finding and no intervention was required. However, case report number two had clinical symptoms and required a first intervention in which the main submaxillary gland was resected, and a second intervention in which the accessory submaxillary gland was removed. Both patients are asymptomatic to date.
Awareness of the possible presence of accessory submaxillary glands and of potential variations of the excretory ducts is useful in diagnosis, as well as leading to more precise treatment for salivary pathology, and allowing surgeons to avoid complications or injuries during surgery.

副颌下腺是一种非常罕见的解剖变异，普通人群中的发病率尚未量化。这些腺体出现病变的情况更为罕见，因此常常未被注意到。
我们描述了两例副颌下腺病例，一例无症状，另一例因涎石病导致主副腺体均患有慢性涎腺炎。尽管我们的诊断是通过计算机断层扫描，但磁共振涎管造影有助于更精确地了解和描述这一实体。
第一例病例报告是偶然发现，无需干预。然而，第二例病例有临床症状，需要进行首次干预，切除主颌下腺，第二次干预则切除副颌下腺。两名患者至今均无症状。
了解副颌下腺可能存在以及排泄导管的潜在变异，有助于诊断，也能为涎腺病变带来更精确的治疗，并使外科医生在手术中避免并发症或损伤。副颌下腺、颌下腺、唾液腺、涎石病、头颈部病变。
