“…The discoloration resembled findings of local lingual thrombosis and infarction following the progression of necrotic changes in previous human cases [16]. In addition, damage to both deep lingual arteries running parallel to the tongue is a possible cause of lingual necrosis in humans [15]. Unfortunately, it could not be concluded whether both deep lingual arteries were damaged, as it was not clear as to which of the two arteries was visualized on sagittal scanning, and both arteries could not be visualized on the same ultrasonogram.…”

“…The primary color-flow Doppler ultrasonographic characteristic of the affected tongue in this case was lack of blood flow in the deep lingual artery, which might have been caused by damage to the artery, resulting in extensive hemorrhage and local thrombosis of the lingual structures [15]. The decreased vascularity might have contributed to the well-defined discoloration in the cranial half of the tongue.…”

“…The venom causes increased capillary permeability, resulting in internal hemorrhages and thromboembolisms associated with damage to the vasculature [12]. Unilateral or bilateral changes to the vascularity of the deep lingual artery due to angiogenesis and changes of vessel width with vessel compression is characteristic of lingual tumors [8,15]. This leads to an imbalance of vascularity and vessel width between the two deep lingual arteries of the tongue [7].…”

Background: In cattle, the lingual diseases are primarily diagnosed postmortem by histopathological examination of the affected tongues obtained after the death or during necropsy. In humans, ultrasonography has been used to provide differential diagnoses, and for preoperative or intraoperative planning of glossectomy in various lingual diseases. This is a bovine clinical case report, in which ultrasonography for sudden swelling of the tongue, which was possibly caused by snake bite, was utilized as a preoperative indication to perform a glossectomy. Case presentation: An eight-month-old female Japanese black calf presented with sudden swelling of the tongue with well-defined discoloration in the cranial region. A 10-MHz linear probe on a portable-type ultrasound machine (MyLabOne VET, Esaote Co., Genova, Italy) was applied to the ventral surface of the tongues in the affected case, and also in five healthy calves under sedation to observe normal tongues. Ultrasonography of the swollen tongue in this case revealed that the ventral lingual muscular layers were severely thickened compared with those of normal tongues. However, the muscle layers were regularly aligned with the echogenic muscular fibers. This resembled the lingual muscular architectures of normal tongues. Color-flow Doppler ultrasonography revealed that blood flow was weakened in the small peripheral vessels in the spaces between the lingual muscular structures, and was lacking in the deep lingual artery between the apex and base of the tongue. This finding was very different than that of normal tongues, which exhibited weakened or rich blood flows. Based on ultrasonographic findings, this case was treated with glossectomy. After recovery, the calf grew up normally with a normal appetite and rumination, and did not exhibit mouth pain behavior. Histopathologically, hemorrhagic necrotic changes, together with focal formation of fibrin thrombus in the lingual blood vessels in the affected tongue, were noted. Conclusions: To the best of our knowledge, the present report is the first description of lingual ultrasonography performed in cattle. In this case, ultrasonography enabled visualization of decreased vascularity, which might be associated with hemorrhage or formation of fibrin thrombus in the suddenly swollen tongue presented.

Objectives: To determine the efficacy and incidence of complications in tumors and in other diseases involving the tongue base treated by transoral surgery with the assistance of endoscopes. Methods:Patients treated for pathologies that compromised the tongue base using a transoral approach with the assistance of endoscopes in the head and neck section of the Otorhinolaryngology service of the Hospital Italiano de Buenos Aires between March 2005 and April 2019 were selected.Central glossectomies and hemiglosectomies were performed with this technique, and through a ventral approach to the tongue, epidermal cysts that compromised the entire extension of the tongue were removed.Results: Three malignant tumors, one lingual thyroid, two epidermal cysts and a central resection of the tongue in a Down patient with severe sleep apnea were performed.In malignant tumors the resections were complete with free margins, and in the others the region could be exposed very well and the pathologies resolved. Conclusion:The use of endoscopes to perform transoral resections of tumors and other pathologies that compromised the tongue base allowed a good exposure of the posterior region of the tongue to the lingual aspect of the epiglottis and made it possible to perform complete resections or perform surgery according to preoperative planning without complications.

“…2 At this point it enters the inferior surface of the tongue and courses as far forward as its tip thus forming the chief source of blood to the structures located both in the floor of the mouth and the tongue. 3,4 However, this anatomy is subject to considerable variation and if not understood well, may pose difficulty in identifying the vessel during surgical, diagnostic or interventional procedures in the head and neck.…”

Study design: Descriptive cross-sectional study. Objective: To determine the variations in origin of the LA and its relationship to surgical landmarks. Background: The Lingual artery (LA) is a branch of the External Carotid Artery (ECA) that constitutes the principal supply to structures within the oral cavity and floor of the mouth. Knowledge of its variant anatomy is therefore vital during radiological and surgical procedures performed in the head and neck region since they may predispose it and other branches of the ECA to iatrogenic injury. There is, however, a dearth of regional data on the same. Materials and Methods: A total of 70 LA dissections were performed bilaterally on 35 human cadavers. The borders of the carotid triangle were identified after which the external carotid artery and its branches were exposed. The pattern of origin and the diameter of the LA was noted and distances from its origin to the CB, GCHB and the HN were measured. Similar measurements were carried out for any variant trunks. Data was collected and analyzed using SPSS (IBM version 27). A paired t-test was used to compare side differences. Representative photos of the vessel and its variations were taken. Results: The LA was found to be present in all cadavers dissected and was bilaterally symmetrical in 43% of cases. Four (4) types of branching patterns were encountered in the present study, the most commonly observed being the solitary LA followed by the LFT, TLT and finally the TLFT. The average diameter was least in the solitary pattern and greatest in the TLT. In relation to the CB, the solitary LA originated at a distance of 1.51 ± 0.89 cm while the LFT, TLT and TLFT originated at a distance of 1.80 ± 0.73 cm, 1.02 ± 0.64 cm and 1.25 ± 0.01 cm respectively from the CB. The mean distance from the origin of the LA to the GCHB was least in the TLT and greatest in the TLFT. With reference to the hypoglossal nerve, the LA was at an average, 0.82 ± 0.15 cm from the HN for the solitary pattern, 1.34 ± 0.86 cm for the LFT, 1.34 ± 0.90 cm for the TLT and 1.38 ± 0.93 cm for the TLFT. Conclusion: The LA in the Kenyan population exhibited a high frequency of variation in comparison to other populations regarding its pattern of origin and relationship to landmarks such as the CB, GCHB and HN. These findings may provide further insight into the understanding of the vascular anatomy to the radiologist and the surgeon to avert complications and improve overall treatment outcome.
