Chronic sinusitis is defined clinically as a sinonasal infection lasting more than 12 weeks. patients may present with symptoms of sinusitis such as nasal obstruction, nasal discharge, facial pain, headache, halitosis, anosmia, etc. it is worth noting is no definite correlation between symptoms and imaging findings of chronic sinusitis and that endoscopic chronic sinusitis may have no imaging correlation as the mucosa is best appreciated on the former 11.

Computed tomography (ct) scanning is the examination of choice in sinusitis, particularly in cases of chronic sinus disease, providing excellent detail of sinus anatomy. however, ct is usually not useful in acute sinusitis, as penaksiran in acute cases is primarily based on clinical findings. good anatomic definition is desirable before surgical intervention. [14, 15, 16, 17, 18, 19] coronal ct imaging is the preferred initial procedure. bone-window views provide excellent resolution and good definition of the complete ostiomeatal complex and other anatomic details that play a role in sinusitis. in addition, the coronal view is best correlated with findings from sinus surgery, with anatomy and pathology visualized in a plane almost identical to that seen by the endoscopist. ct provides an excellent anatomic display of soft-tissue attenuation. this depiction includes fluid levels and polypoid masses within the normally air-filled cavities of the sinuses, nasal cavity, and postnasal spa X-ray film of the face frontal, nose-chin and lateral projection. volume formation of the right maxillary sinus. marker. negativ. a images of the x-ray face. A characteristic feature on ct sinuses is sclerotic thickened bone (hyperostosis) involving the sinus wall from a prolonged mucoperiosteal reaction. intrasinus calcificationmay be present. the presence of opacification is not a good discriminator from an acute sinus infection. there are five main patterns x images ray sinusitis of chronic inflammatory disease that classify the disease into distinct anatomical/pathological groups and are dependent on the drainage pathways affected. this classification helps the surgeon to select the type of surgery needed 12: 1. ostiomeatal complex pattern: maxillary sinus, anterior ethmoid air cells, and frontal sinuses are affected due to obstruction of the ostiomeatal complex dua. infundibular pattern: isolated obstruction to the ethmoid infundibulum and/or maxillary sinus ostium tiga. sphenoethmoidal recess pattern: inflammatory changes in the sphenoethmoidal recess obstruct the sphenoid sinus in isolation or in conjunction with the posterior ethmoidal air cells 4. sinonasa

Computed tomography (ct) scanning is the examination of choice in sinusitis, particularly in cases of chronic sinus disease, providing excellent lebih jelasnya of sinus anatomy. x images ray sinusitis the ostiomeatal units are brilliantly shown on ct scans, which provide greater definition of the pathology than do other images, especially within the sphenoid and ethmoid sinuses.
To evaluate the pattern of sinusitis, one must understand the drainage of various sinuses. the anatomy of drainage revolves around the ostiomeatal unit, which is not a single morphologic structure but a combination of the following structures: 1. middle turbinate 2. ethmoid bulla 3. uncinate process 4. maxillary infundibulum lima. hiatus semilunaris (ie, space beneath the middle turbinate) 6. maxillary os the hiatus semilunaris is a space between the uncinate process (anteroinferiorly) and the ethmoid bulla (posterosuperiorly). the anterior group of ethmoid air cells drains into the anterior aspect of the hiatus semilunaris through the frontonasal duct. the middle group drains into the hiatus semilunaris on or above the ethmoidal bulla. the frontal sinus drains through the frontonasal duct or through the anterior ethmoidal cells into the hiatus semilunaris. the maxillary infundibulum drains into the posterior part of the hiatus semilunaris. the frontal, maxillary, anterior, and middle See full list on emedicine. medscape. com.

The american college of radiology (acr) regards noncontrast ct scanning as the examination of choice in recurrent or chronic sinus disease. all imaging findings are interpreted in conjunction with clinical and endoscopic findings. mri is a complementary study when aggressive disease is being evaluated with ophthalmic/intracranial complications, especially in fungal disease in immunocompromised patients and in characterization of a sinus mass. [28] the acr recommendations for sinusitis in children include the following[29] : 1. imaging studies are not recommended for uncomplicated acute sinusitis: 2. ct of the paranasal sinuses without iv contrast is recommended for persistent sinusitis (worsening course or severe presentation, or not responding to treatment), recurrent sinusitis, or chronic sinusitis, or to define paranasal sinus anatomy before functional endoscopic sinus surgery. 3. ct or mri of the head and paranasal sinuses with iv contrast is recommended for sinusitis with clinic
