Nowadays, computed tomography(CT) is frequently used in the evaluation of patients with paranasal
It is shown that there is a significant correlation between the prevalence of incidental paranasal
sinus abnormalities (IPSA) detected in MRI and the presence of clinical symptoms associated with paranasal
Invasive fungal rhinosinusitis (IFRS) is a fatal disease of the nose and paranasal
sinuses that typically affects immunocompromised patients.
sinuses are hollow spaces in few bones of the skull.
Divided into brief study units, this textbook introduces the main concepts in otorhinolaryngology, covering the anatomy, physiology, and immunology of the nose, paranasal
sinuses, and face, diagnostic evaluation of the nose and paranasal
sinuses, and specific diseases; the anatomy, physiology, examination, and conditions of the oral cavity and pharynx, ear, facial nerve, lateral skull base, external neck, larynx, and trachea; and hearing, voice, and speech and language disorders.
Small cell neuroendocrine carcinoma (SCNEC) is a rare disease of nose and paranasal
sinus cancer represents a small portion of the head and neck cancer, approximately 5% of all head and neck tumors .
sinus foreign bodies (PNS FBs) are commonly secondary to gunshots and accidental sharp materials [1-3].
Acquired orbital respiratory cysts are caused by extension of paranasal
sinus mucosa either by herniation because of trauma or by pressure erosion of the thin intervening bone by an expanding mucocele .
It could be commonly caused by air escaping into the intracranial space after head traumas or during some surgical managements, such posterior fossa surgeries in the sitting position, evacuation of a subdural hematoma, anesthesia with nitrous oxide, ventriculoperitoneal (V/P) shunt application, paranasal
sinus surgery, and lumbar drainage (1, 2).
sinus mucoceles are mucus-containing cystic structures with an epithelial lining that completely fills in the paranasal
sinus osteomas are benign osteogenic lesions, often diagnosed incidentally on computed tomography (CT).
