Sonographic assessment of the Submandibular Space
Clinical radiology, 2004Co-Authors: David C. Howlett, F. Alyas, K.t. Wong, Khari Lewis, Michael Williams, A.b. Moody, Anil T. AhujaAbstract:There is a wide variety of pathological processes which may present with swelling in the Submandibular Space. Although the Submandibular gland is the most important structure in this region, there are a number of extraglandular causes of swelling which frequently mimic Submandibular gland enlargement. In this review the use of high-resolution ultrasound in the assessment of the Submandibular gland and adjacent structures is discussed and illustrated.

High-resolution sonography of the Submandibular Space: anatomy and abnormalities.
AJR. American journal of roentgenology, 2002Co-Authors: A. S. C. Ching, Anil T. AhujaAbstract:703 e attempted to provide a framework to understand the normal anatomy and to outline the features of lesions in the Submandibular Space. Techniques In most cases, a high-resolution (7-12– MHz) linear transducer is useful, although a higher frequency (>12-MHz) transducer with a small contact surface area may be necessary in a smaller or angular region. The images were obtained mainly in an axial plane using a Submandibular view with oblique or coronal High-Resolution Sonography of the Submandibular Space: Anatomy and Abnormalities A. S. C.

Severe Soft Tissue Infections of the Head and Neck: A Primer for Critical Care Physicians
Lung, 2009Co-Authors: Steven C. Reynolds, Anthony W. ChowAbstract:Patients with severe infections of the potential Spaces of the head and neck are commonly managed in the ICU. These infections may present with devastating complications such as airway obstruction, jugular septic thrombophlebitis, lung abscess, upper airway abscess rupture with asphyxiation, mediastinitis, pericarditis, and septic shock. A thorough understanding of the anatomy and microbiology of these infections is essential for proper management of these patients. Retropharyngeal, danger, prevertebral, lateral pharyngeal, and Submandibular Space infections and their site-specific clinical manifestations, complications, and therapeutic interventions are discussed.

Odontogenic Infection Pathway to the Parapharyngeal Space: CT Imaging Assessment
Journal of Maxillofacial and Oral Surgery, 2020Co-Authors: Ichiro Ogura, Yoshiyuki Minami, Yoshihiro Sugawara, Ryo Mizuhashi, Fumi Mizuhashi, Makoto Oohashi, Hisato SaegusaAbstract:Parapharyngeal Space infection may lead to severe and potentially life-threatening complications. The aim of this study was to assess the odontogenic infection pathway to the parapharyngeal Space using CT imaging. Nineteen patients in mandibular odontogenic infections with abscess who underwent contrast-enhanced CT were evaluated in this study. We reviewed the location of abscess and spread of odontogenic infections to the different components of the buccal Space, Submandibular Space, sublingual Space, masticator Space and parapharyngeal Space using CT imaging. The location of abscess and spread of odontogenic infections were analyzed with the Pearson Chi-square test. Regarding the odontogenic infection pathway to parapharyngeal Space, the masticator Space (100%) was the most frequent, followed by the buccal Space (85.7%), Submandibular Space (85.7%) and sublingual Space (57.1%), while those without parapharyngeal Space, the Submandibular Space (83.3%) was the most frequent, followed by the buccal Space (75.0%), masticator Space (58.3%) and sublingual Space (33.3%). The masticator Space was significant Space in patients with/without parapharyngeal Space infection (P = 0.047). CT imaging could be an effective method in assessment of odontogenic infection pathway to the parapharyngeal Space. The odontogenic infection in masticator Space tends to display spread of parapharyngeal Space.

Spread of odontogenic infections in the elderly: Prevalence and characteristic multidetector CT findings
International Journal of Diagnostic Imaging, 2017Co-Authors: Ichiro Ogura, Norihito Iizuka, Marie Ishida, Eri Sawada, Takashi KanedaAbstract:Purpose: To analyze spread of odontogenic infections in the elderly, especially the prevalence and characteristic multidetector computed tomography (MDCT) findings. Materials and methods: Ninety-seven patients with odontogenic infection who underwent 64-row MDCT were evaluated in this study. The study patients comprised 31 elderly patients (60 years) and 66 adults (< 60 years). Age, gender, location of causal tooth, and spread of odontogenic infections with MDCT were analyzed. Results: The elderly patients (74.2%) had higher ratio with female compared to the adults (57.6%). The buccal Space (93.5%) was the most common spread of odontogenic infections for the elderly patients, followed by the masticator Space (54.8%) and Submandibular Space (45.2%), whereas the buccal Space (97.0%) was the most common spread of odontogenic infections for the adults, followed by Submandibular Space (65.2%) and masticator Space (51.5%). Logistic multivariate regression analysis for odontogenic infections in the elderly demonstrated that the gender (odds ratio = 3.462, P = .024) and Submandibular Space (odds ratio = 0.168, P = .013) were significant variable. Conclusions: The study showed the prevalence and characteristic MDCT findings of spread of odontogenic infections in the elderly.

Double thyroid ectopia (with incidental papillary thyroid microcarcinoma) (2010: 8b)
European Radiology, 2010Co-Authors: Alexandra Borges, Mariluz Martins, Saudade AndréAbstract:We present the case of a 45-year-old man with a long-standing history of a slow-growing left Submandibular mass. Imaging was diagnostic as it disclosed an absent orthotopic thyroid gland and heterogeneous masses, with both solid and cystic components, as well as calcifications in the left sublingual/Submandibular Space and in the left paramedian aspect of the tongue base, consistent with double thyroid ectopia, originating from central and lateral thyroid anlages, respectively. Pathology confirmed an ectopic thyroid goiter in the left Submandibular Space with an incidental papillary microcarcinoma. Scintigraphy also demonstrated ectopic thyroid tissue in the left tongue base.
