Patients and methods
Six patients with vascular or suspected vascular anomalies seen in the Department of Oral and Maxillofacial Surgery of Thomas Jefferson University Hospital (TJUH) for consultation and/or treatment between 1997 and 1999 composed the study group. CT, MRI (4 of 6 patients), US, and Doppler imaging were performed in the Department of Radiology, TJUH. Angiography was performed in 2 patients. All imaging analyses were written or reviewed by 2 authors (L.N.N. and V.M.R.), and US and Doppler studies
Case 1
MRI showed a lobulated mass that did not involve bone; progressive enhancement on the dynamic injection of contrast was in favor of a venous malformation. US/Doppler findings were diagnostic. Accurate measurements of the anatomic position of the lesion in relation to skin surface and buccinator muscle were made. Multiple “cystic” spaces within the mass were seen to be venous spaces when compressed by the US probe and showed venous flow on spectral analysis. Color Doppler gave no evidence of
Discussion
Ultrasound clinical studies in the OMS literature of the 1980s and 1990s can roughly be divided into 4 regions: neoplastic and inflammatory processes in major salivary glands,5, 6, 7, 8, 9, 10 neoplastic and non-neoplastic neck masses,6, 7, 8 inflammatory and abscess localization in oral and facial soft tissues,8, 9, 11 and intraoral soft tissue neoplasms.12, 13
Among this group of reports, 2 studies7, 9 also critically examined the clinical applications and diagnostic limitations of US in OMS.

Parotid Lymphangioma of adult: A case report
2022, Annals of Medicine and SurgeryCitation Excerpt :FNAC is also used for the investigation. USG of Lymphangioma shows multicystic mass which is hypoechoic within thin walls [10]. A thin-walled, multicystic, homogenous mass with smooth septa can be appreciated on the CT scan of parotid lymphangioma [11].
Reverse blood flow in cervicofacial veins after venous ligations: Potential implications in microsurgery
2021, Journal of Plastic, Reconstructive and Aesthetic SurgeryCitation Excerpt :There is so far no gold standard on how to explore the cervicofacial venous system. We chose Doppler ultrasound as it is a non-invasive, readily available, reproducible and cost-effective technique for the examination of cervicofacial veins.12 We chose to study the STV, FV and IJV because these vessels are easy to explore with a Doppler ultrasound13,14 and frequently used as recipient vessels in microsurgical reconstruction of the head and neck.7

2017, Oral Surgery, Oral Medicine, Oral Pathology and Oral RadiologyCitation Excerpt :Ultrasonography is quick, easy, relatively inexpensive, and free of ionizing radiation; moreover, it is a painless, noninvasive, and nonthreatening method for the detection, evaluation, and follow-up of lesions. In addition, DUS can be used in deeply situated or large lesions and has Doppler capability.2,18,19 Exposure times are relatively short compared with MRI, which often requires sedation in children younger than 10 years of age and in patients with claustrophobia.18
Extensive arteriovenous malformation in the face of a pediatric patient - Case report
2014, Revista Portuguesa de Estomatologia, Medicina Dentaria e Cirurgia MaxilofacialCitation Excerpt :The proper diagnosis of these malformations should be initiated from an early history interview and a detailed clinical examination of the lesion. Imaging exams such as ultrasound, MRI, CT scan with contrast and angiography are crucial.11 The ultrasonography presents advantages such as low cost, easy availability and it spares the patient's exposure to ionizing radiation.
