[Ultrasonographic features of Castleman disease in the head and neck: a report of 7 cases].

Purpose: To summarize the ultrasonographic features of head and neck Castleman disease (CD), and to clarify its diagnostic key points.

Methods: Seven patients with head and neck CD confirmed by histopathology were collected from Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. The clinical features and ultrasound findings of the patients were evaluated.

Perforator navigation using color Doppler ultrasound and three-dimensional reconstruction for preoperative planning of optimal lateral circumflex femoral artery system perforator flaps in head and neck reconstruction.

Background: The authors introduce an algorithm for preoperative planning of optimal lateral circumflex femoral artery system perforator flap (LCFAPF) supplied by the best quality and the easiest dissection of the perforators and the source vessels for simplified and customized strategies in head and neck reconstruction with perforator navigation using color Doppler ultrasound and three-dimensional reconstruction (3D-CDUS PN).

Methods: Between June 2011 and September 2015, a prospective cohort study was performed with an algorithm based on defect site, perforator type, and pedicle length using 3D-CDUS PN to select optimal perforators arising from the different branches of LCFA in 108 patients. The optimal perforator and flap were determined by perforator caliber and quality, difficulty in flap dissection, and length of the source vessels.

Clinical features and treatment outcomes of immunoglobulin g4-related sclerosing sialadenitis.

Idiopathic enlargement of salivary glands used to be confusing in diagnosis until immunoglobulin G4 (IgG4)-related sclerosing sialadenitis was proposed as a possible answer. In this case series, we reported the clinical features and management outcomes in 16 patients with IgG4-related sclerosing sialadenitis. We retrospectively studied 16 patients in clinical examination, serology, pathology, and sonography features.

[Ultrasonographic study on the relationship between the thickness of squamous cell carcinoma of tongue and cervical lymph node metastasis].

Purpose: This study aims to investigate the correlation between the thickness of the tongue carcinoma and cervical lymph node metastasis obtained with ultrasonography.

Methods: The tumor thickness of 37 primary tongue cancers were measured in the sonogram by the intraoral ultrasonography. The cervical lymph nodes were scanned, and the number, size, internal echo, and blood stream were measured to evaluate the nature.
