The maxillary sinuses are the largest of the paranasal sinuses, located one on each side as well as totally fill the bodies of the maxillae.

MAXILLARY SINUS. As the nerve runs along the roof of the maxillary sinus, it supplies the maxillary sinus itself and the anterior teeth of the upper jaw via the anterior and middle superior alveolar nerves. OF ORAL PATHOLOGY AND MICROBIOLOGY ,MRDC 16 DEPARTMENT OF ORAL PATHOLOGY AND MICROBIOLOGY MRDC. b) drains into the superior meatus of the nasal cavities. The nasal cavity has a diverse blood supply arising from . 1 Especially, fractures of the clivus as well as the sella turcica-sphenoid sinus complex are found to be associated with vascular injury. . These arteries are ultimate branches of the maxillary artery. Blood Supply and Lymphatics. The posterior and anterior superior alveolar branches of the maxillary and infraorbital arteries respectively supply blood to the sinus. Anatomy of the Maxillary Sinus sinus is primarily derived from the The procedure of choice to restore this The maxillary sinus is a pyramid- posterior superior alveolar artery and anatomic deficiency is maxillary sinus shaped cavity with its base adjacent to the infraorbital artery, both being floor elevation (sinus lift). The blood supply comes from the superior alveolar branches of the maxillary artery. Blood supply to the frontal sinuses comes through the supraorbital artery. It is the most significant paranasal sinus and appears pyramidal in shape. This article will discus the anatomy and course of the maxillary artery. READ MORE . The sinuses humidify the inhaled air and contain cells that participate in the immune system response. The lymphatics of the maxillary sinuses drain to the submandibular nodes. blood supply of maxillary sinus. The floor of the antrum is approximately 10mm below the nasal floor in adults. Nerve supply : Infra orbital, anterior, middle and post superior alveolar nerves. The nose and the paranasal sinuses provide resonance to the voice and humidify and warm inhaled air.

The blood supply to the maxillary sinus is derived primarily from the maxillary artery and to a lesser degree from the anterior ethmoidal and superior labial arteries. The paranasal sinuses are extensions of the nasal cavity into surrounding bones. Blood supply to the maxilla is via branches of the maxillary artery. .

2. The lateral maxilla is supplied by branches of the posterior superior alveolar artery (PSAA) and the infraorbital artery (IOA) that form an anastomosis in the bony lateral antral wall, which also supplies the Schneiderian membrane. a) is lined by stratified squamous epithelium. Venous drainage is via the supraorbital and superior ophthalmic veins. The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, and drains into the middle meatus of the nose. . The average dimensions of the adult maxillary sinus are 25-35mm in width, 36-45mm in height, and 38-45mm in length. Its primary function is sensory supply to the mid-third of the face. An Anatomic and Clinical Consideration, 2nd ed., Williams & Wilkins, Baltimore, 1951. The maxilla along with the portions of the inferior concha . There are significant anastomoses between these two arteries in the lateral antral wall. Part of the blood supply distribution to the face, neck, and brain is taken up by the maxillary artery. . It is from the maxillary artery that various branches arise, supplying the bones of the jaws, the teeth, and their supporting tissues. Luke warm water is irrigated through the sinus and this drains out through the osteum along with the sinus exudates. branches of internal maxillary artery-infraorbital artery-superior alveolar branches-greater palatine artery. Usually extends from the infraorbital canal to the lateral wall of the sinus. The blood supply to the maxillary sinus is derived primarily from the maxillary artery. The paranasal sinuses (maxillary, frontal, ethmoidal, sphenoid) are air-filled cavities within the bones of the skull that surround the nasal cavity. The Maxillary Artery Branches.

It is this artery that is of particular interest in dentistry. The blood supply to the maxillary sinus is principally derived from the posterior superior alveolar artery and the infraorbital artery, both being branches of the maxillary artery. Sixty to 70 percent of these types of tumors occur in the maxillary sinus in the cheek, while 20 to 30 . Introduction. lymphatic drainage for maxillary sinus is through . Both maxillary sinuses are located lateral to the nasal cavities and under the orbits. It is basically involves inserting a canula into the maxillary sinus trough the inferior meat us. Its primary function is to supply blood to the lower section of the body. The sphenoid sinuses are paired spaces formed within the body of the sphenoid bone, communicating with the roof of the nasal . The purpose of the present study was to assess the relationship between the posterior superior alveolar artery (PSAA), which plays an important role in the maxillary sinus blood supply, and maxillary sinus pathologic entities using cone-beam computed tomography (CBCT). The two maxillary sinuses are located below the cheeks, above the teeth and on the sides of the nose. The primary function is the protection of the organism which is achieved by different mechanisms. Blood Supply. MAXILLARY SINUS 1 ; 2. The goal of this study was to describe the arterial architecture of the maxillary sinus region in respect to sinus lift procedures. . The paranasal sinuses are air-filled extensions of the nasal cavity. The largest paranasal sinuses, maxillary sinuses, occupy the maxilla bone. ; After the development of paranasal sinuses the maxillary sinus are . The Maxillary sinus is rudimentary at birth and gradually expands. The anterior superior alveolar artery runs downward to supply the anterior teeth and the anterior part of the maxillary sinus. The average volume of the sinus is 15ml. It can be bony or fibrous septum . b. Venous Blood. Start studying Maxillary Sinus. 3. . Maxillary Sinus. In a few . It is a common problem and 70% of adult males have had experience epistaxis (nose bleeding) over the age of 60 years, it is also common in children. Blood supply of maxillary sinus. It is essential to determine the sites of the IOA and PSAA for surgical planning as they anastomose and form a double arterial arcade that surrounds the maxillary sinus and damage to these vessels can cause bleeding. The goal of this study was to describe the arterial architecture of the maxillary sinus region in respect to sinus lift procedures. They are named for the bone that encloses them: frontal, ethmoid, sphenoid, and maxillary sinuses. There are 3 arteries that supply the maxillary sinus (i.e., the posterior superior alveolar, infraorbital, and posterior lateral nasal arteries), any of which may be encountered during lateral approach sinus elevation surgery. These findings suggest the possibility that the sensory neurons and blood vessels in the anterior teeth are derived from .

As the maxilla is deemed part of the midface and the mandible part of the lower face respectively, it is logical to assume that they have separate neurovasculature. The average dimensions of the adult maxillary sinus are 25-35mm in width, 36-45mm in height, and 38-45mm in length. . The earliest phase of pneumatization is directed . Blood Supply and Lymphatics. Veins carry blood from the tissues of the body back to the heart, following the same general arrangement as the arteries. richly supply the residual ridge and, particularly, the mucoperiosteal tissues. As a branch of the trigeminal nerve, the maxillary nerve is often implicated in trigeminal neuralgia, a rare condition . This intraosseous anastomosis was found in all of the specimens. Cancerous nasal cavity or sinus tumors are rare, with only about 2,000 being diagnosed in the United States each year. This study deals with maxillary arteries relevant to sinus floor elevation surgery and examines the vascularization of the lateral maxilla . Both arteries give extra Therefore, any damage or infection to this rich vasculature necessitates the need for endodontic or surgical treatment to restore dental functionality and form. blood supply of maxillary sinus. . The arterial supplies are from the facial, infraorbital, and greater palatine arteries, and their venous drainage is into the facial, infraorbital, and greater palatine veins. The nose is the protruding structure at the center of the face that serves as the organ of smell and entrance of the respiratory system.
