CT scan images after application of radioactive laced nasal steroids using long nozzle. Note the reach of the medication into the area where nasal polyps originate Endoscopic sinus surgery , advocated and popularized by Professor Stammberger, is often very effective for most people, providing rapid symptom relief.
Silent sinus syndrome is a spontaneous, asymptomatic collapse of an air sinus (usually the maxillary sinus and orbital floor) associated with negative sinus pressures. It can cause painless facial asymmetry, diplopia and enophthalmos. Diagnosis is suspected based on symptoms, and can be confirmed using a CT scan.
Surgery is often implemented in all stages of paranasal sinus and nasal cavity cancer. [1] The main goal of surgery is to remove cancerous tissue. [1] Surgery is typically followed by chemotherapy and radiation therapy, to kill off any remaining cancer cells. [1] The type of surgery performed depends on the extent to which cancerous tissue has ...
3) The ability to obtain cultures at the time of lavage, when clinically warranted or indicated by CT-scan evidence. 4) Avoiding the need for exposure to radiation, as fluorescence is used in its stead. 5) Lack of interference in anatomy. Functional Endoscopic Sinus Surgery (FESS) is one of the newer modalities in treatment of Chronic Sinusitis ...
Onodi cells typically extend back to lie superolateral to the sphenoid sinus and thus near the optic nerve and internal carotid artery. [9] Failure to recognize an Onodi cell on CT scan before surgery may put these structures at risk. One study found that an Onodi cell was present in 26.6% of males and 19.1% of females.
Before and after surgical restoration of the lateral wall (arrow in right-side image) to simulate the function of the missing inferior turbinate. A 2015 meta-analysis identified 128 people treated with surgery from eight studies that were useful to pool, with an age range of 18 to 64, most of whom had been experiencing ENS symptoms for many years.
Malignancies of the paranasal sinuses comprise approximately 0.2% of all malignancies. About 80% of these malignancies arise in the maxillary sinus. Men are much more often affected than women. They most often occur in the age group between 40 and 70 years. Carcinomas are more frequent than sarcomas. Metastases are rare.
CT images of the head are used to investigate and diagnose brain injuries and other neurological conditions, as well as other conditions involving the skull or sinuses; it used to guide some brain surgery procedures as well. [2] CT scans expose the person getting them to ionizing radiation which has a risk of eventually causing cancer; some ...
