“…This provided a lateral view of the tongue body, submental musculature, and mandible. Similar images of the tongue have been described in previous work on US imaging of the tongue during speech (50 -52), measurement of GG depth (9,19), and clinical imaging of upper airway (40).…”

“…Computed tomographic imaging also involves exposure to radiation. Ultrasound (US) imaging offers potential advantages for clinical imaging of the upper airway (40) and has previously been used to demonstrate dynamic upper airway movements during swallowing and speech assessments (50,51). It is noninvasive, does not emit radiation, can resolve soft tissue structures, and can display cross-sectional anatomy and tissue motion in real time (52).…”

Upper airway muscles are important in maintaining airway patency. Visualization of their dynamic motion should allow measurement, comparison, and further understanding of their roles in healthy subjects and those with upper airway disorders. Currently, there are few clinically feasible real-time imaging methods. Methods such as tagged magnetic resonance imaging have documented movement of genioglossus (GG), the largest upper airway dilator. Inspiratory movement was largest in the posterior region of GG. This study aimed to develop a novel ultrasound (US) method to measure GG movement in real time. We tested 20 healthy, awake subjects (21-38 yr) breathing quietly in the supine posture with the head in a neutral position. US images were collected using a transducer positioned submentally. Image correlation analysis measured regional displacement of GG within a grid of points in the midsagittal plane throughout the respiratory cycle. Typically, motion began before inspiratory flow in an anteroinferior direction and peaked in midinspiration. Average peak displacements of the anterior, posterior, superior, and inferior grid points were 0.44 ± 0.23 (mean ± SD), 0.57 ± 0.35, 0.38 ± 0.20, and 0.62 ± 0.41 mm, respectively. Largest displacements occurred in the most inferoposterior part (0.70 ± 0.48 mm). This method had good intrarater repeatability within the same testing session, as well as across sessions. We have devised a simple noninvasive US method, which should be a useful tool to assess GG movement in normal subjects and those with sleep-disordered breathing.

“…41 Lack of mobile venous valves is also one of the thrombosis signs. 7 CONTRAST VS NON-CONTRAST CT Similar to conclusion of Avsenik et al about noncontrast CT in case of cerebral venous sinus thrombosis, our case clearly proves that non-contrast multislice CT as an emergency examination has a high value for diagnosis of IJV thrombosis. 43 Simultaneously with that statement, Leci-Tahiri et al and Tannenbaum et al insist on a need to perform contrast enhanced CT as it improves evaluation for acute bleeding and osseous injury and for additional pathologic conditions such as: 1) infection, 2) neoplasm, and 3) vascular dissection or thrombosis.…”

“…19 Rhys and Tajima et al applied the word "acute" describing a symptomatic IJV thrombosis. 7,20 And it is very common in English-language publications to divide DVT into acute (first 27 days) and chronic (28 days or longer) (synonym: post-thrombotic syndrome) form according to the clinical course. 21 The authors and practitioners from some East-European countries categorize vein thrombosis into three forms: 1) acute…”

This report documents a first unilateral and then bilateral internal jugular vein (IJV) thrombosis as a result of repeated injections of heroin, which is rare in a practice of oral and maxillofacial surgeon. The patient was a 21-year-old male who was referred to a hospital with the diagnosis of phlegmon of the right neck. Emergency non-contrast computed tomography (5 images and 1 Supplemental Video are presented) revealed a hyperattenuating content in the lumen of expanded right IJV which fills its entire length. The patient received initial treatment according to the protocol. Ultrasound (US) (2 images and 2 Supplemental Videos are presented) in a first 24 hours supported the diagnosis describing a case as occlusive acute thrombosis. After 4 days of a positive dynamic the patient was transferred to outpatient mode. In a 10 day US examination (2 images and 2 Supplemental Videos are presented) simultaneously with positive changes in the lumen of a right IJV (partial clot lysis) an appearance of a left IJV thrombosis was noted. Analysis of thrombotic conditions of the neck, diagnostics methods, treatment options, and complications are performed.

The three pairs of major salivary glands include the parotid, submandibular, and sublingual. The minor salivary glands are numerous and are located in the mouth and oropharynx.All salivary glands are exocrine and have serous or mucous acini and excretory ducts. Serous acini have basally located nuclei, granular basophilic cytoplasm, and cytoplasmic zymogen PAS+ diastase-resistant granules, and they secrete amylase (Fig. 5.1 ). Mucous acini have basally located nuclei, clear vacuolated cytoplasm, and cytoplasmic sialomucin vacuoles, and they secrete mucin. The ductal system begins distally in the intercalated ducts, which are lined with cuboidal epithelium. The cells have central nuclei in communication with the larger striated ducts which are lined by mitochondria-rich columnar eosinophilic cells. The more proximal interlobular ducts are lined by pseudostratified columnar epithelium with scattered mucinous cells. Myoepithelial cells surround the secretory acini and the intercalated ducts.
