“…45,46 These malformations are usually present at birth and can range from being asymptomatic to having significant manifestations. 46,50,51 The sequelae of these shunts can be quite serious with cases of pharyngeal abscess secondary to lymphovenous malformations reported in the literature. 11 Cardiac lymphovenous malformations, though extremely rare, have also been reported with significant effects on cardiac physiology.…”

The lymphatic system is a vast network of vessels that functions to return excess fluid from the interstitial space to the blood stream. 1 Excess interstitial fluid is drained by lymphatic capillaries, which are composed of a single layer of lymphatic endothelial cells that overlap with each other. The overlapping cells are thought to act as primary valves allowing flow of interstitial fluid into lymphatic vessels but limiting outflow. [2][3][4] Lymph then flows from these capillaries into collecting lymphatics 5 which have a layer of lymphatic muscle cells (LMCs) that work to transport lymph through rhythmic contraction. 6,7 This intrinsic force from LMCs occurs in conjunction with extrinsic compressive force from surrounding tissue to propel lymph through the lymphatic system. 6,8 A secondary system of intraluminal valves within the lymphatic collecting ducts themselves prevents backflow of lymphatic fluid toward the capillaries. 6,8,9 Lymph then travels through lymph nodes into post-nodal lymphatic ducts which converge into either the thoracic duct or the right lymphatic duct; these are classically described as emptying into the junction of the subclavian veins and internal jugular veins on the left and right side, respectively. 9,10 These connections are the body's two major anatomic lymphovenous shunts, a term which refers to the anastomoses, be it natural or surgical, between the lymphatic system and the venous system. 11 | ANATOMIC ALLY NORMAL LYMPHOVENOUS S HUNTS | Thoracic duct and right lymphatic ductThe natural anastomosis between the thoracic duct and the subclavian vein represents a well-known anatomic lymphovenous shunt. 12 The thoracic duct (TD) most commonly originates from the cisterna

Objective This study aimed to investigate the normal volumetric space and variations in the measurements of different landmarks in adults with different skeletal relations of the maxilla and the mandible based on CBCT data. The study also analyses these landmarks to locate any correlations. Background Numerous studies in orthodontics have found a relationship between orthodontic treatment and changes in the anatomy and function of the airway. Severe changes in airway morphology can cause breathing difficulties, lower quality of life, and even result in life-threatening conditions such as obstructive sleep apnoea. Consequently, orthodontic diagnosis and treatment planning require a thorough understanding of the airway space and its function. Methods The present retrospective study was conducted using CBCT records of 120 adult patients, containing 40 samples of each skeletal class (20 males and 20 females). The boundaries were defined for the 3 major regions: the nasopharynx, the oropharynx, and the hypopharynx. Various measurements were recorded across these regions, as well as selective cephalometric landmarks. The obtained data was used to calculate average and standard deviation, while regression analysis was used to evaluate correlations and t-test was used to test statistical significance of gender differences. Results The results demonstrate that skeletal Class III individuals exhibit a reduced airway volume in the nasopharynx compared to other groups, whereas skeletal Class II individuals displayed a diminished airway volume in the hypopharynx. A strong correlation was observed for Sella turcica parameters. There were no significant differences in skeletal parameters across genders. Nasopharynx cavity volume demonstrated significant differences between skeletal Class I–Class III as well as between skeletal Class II–Class III. Hypopharynx cavity volume also demonstrated significant differences between skeletal Class I–Class II and between skeletal Class II–Class III. Conclusion The major findings are the presence of a reduced nasopharyngeal volume in skeletal Class III malocclusions while skeletal Class II individuals displayed a diminished hypopharyngeal volume, making these critical areas to consider during the diagnostic and orthodontic treatment planning stages. This study also revealed a consistent correlation between Sella turcica parameters across various facial skeletal profiles, with skeletal Class II patients exhibiting a distinct pattern and skeletal Class I and Class III demonstrating an average relationship.
