title: Ultrasonographic appearance of lipoma in the oral and maxillofacial region.
abstract: OBJECTIVE
  To summarize the clinical situation, ultrasonographic appearance, diagnosis, and treatment experience of lipoma in the oral and maxillofacial region.
  
  
  METHODS
  Twenty-two patients with lipoma in the oral and maxillofacial region were retrospectively investigated in regards to clinical appearance, ultrasonographic appearance, and treatment.
  
  
  RESULTS
  Among the 22 patients, the ratio between males and females was 2.67:1. The age ranged from 21 to 72 years with a mean age of 47 years. The most common location was the submandibular region. Ultrasonographic appearance of lipoma in the oral and maxillofacial region was round or elliptical in shape with intact or mostly intact capsule. The internal architecture in the majority of patients was hypoechoic with echogenic lines or spots. Complete surgical resection was performed, and no recurrence occurred during the follow-up period.
  
  
  CONCLUSIONS
  Diagnosis of lipoma in the oral and maxillofacial region can be made based on the clinical examination and ultrasonography. Complete surgical resection is the treatment of choice.
