Orbital Cellulitis : Cellulitis

Penile CellulitesCellulitis is an acute spreading pyogenic inflammation. The causes of the celluilits are bacteria most ..... The septum is the pre-stage of a cellulitis. The orbital septum, thus, is a layer of fascia extending vertically from the periosteum of the orbital rim to the levator aponeurosis in the upper eyelid and to the inferior border of the tarsal plate in the lower eyelid. Orbital cellulitis and preseptal cellulitis are the primary infections of the ocular adnexal and orbital tissues. Orbital cellulitis is an infection of the soft tissues of the orbit posterior to the orbital septum, distinguishing it from preseptal cellulitis, which is an infection of the soft tissue of the eyelids and periocular region anterior to the orbital septum. Orbital cellulitis has several causes and may be associated with serious complications. Prompt diagnosis and proper management are necessary for curing the patient with orbital cellulitis.The orbital cellulitis takes place because of the three major causes. Firstly the orbital cellulitis is caused due to extension of the infection from the periorbital structures. It is also caused from the extension of paranasal sinuses. The other causes of the orbital cellulitis are the extension of face, globe, and lacrimal sac. Secondly, the orbital cellulitis is also caused sue to direct inoculation of the orbit from the trauma or the surgery. The orbital cellulitis is also because of the hematogenous spreading of the bacteremia. The medial orbital wall is thin and not only perforated by numerous blood vessels and nerves, but it also has several other defects. This combination of thin bone, foramina for neurovascular passage, and naturally occurring defects in the bone permits for easy communication of infectious material between the ethmoidal air cells and the subperiorbital space in the medial aspect of the orbit. The most common place of a subperiorbital abscess is along the medial orbital wall. The periorbita is adherent relatively loosely to the bone of the medial orbital wall, which permits abscess material to easily move laterally, superiorly, and inferiorly within the subperiorbital space.In addition, the lateral extensions of the sheaths of the extraocular muscles, the intermuscular septa, spreads from one rectus muscle to the next and from the insertions of the muscles to their origins at the annulus of Zinn posteriorly. Posteriorly in the orbit, the fascia between the rectus muscles is thin and frequently incomplete allowing easy extension between the extraconal and intraconal orbital spaces. Venous drainage from the middle third of the face, including the paranasal sinuses, is mainly via the orbital veins, which are without valves, permitting the passage of infection both anterograde and retrograde. Infectious material might be introduced into the orbit directly from accidental or surgical trauma.Cellulitis ContagiousCellulitis is a disease of the skin and underlying tissues. It might affect any area of the body.
