Sinus transillumination What is transillumination? Transillumination
Transillumination
Transillumination is the technique of sample illumination by transmission of light through the sample. Transillumination is used in a variety of methods of imaging. In microscopy transillumination refers to the illumination of a sample by transmitted light.
Paranasal sinuses
Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones in which they are located.

The frontal sinus can be examined in a similar manner by directing the light upward under the medial aspect of the eyebrow and observing the glow above the eye.

What is transillumination in medical terms?
Transillumination offers a quick and simple way to check your organs and body for abnormalities. Keep in mind that transillumination is a first step and is used in conjunction with other tests. If transillumination yields abnormal results, your doctor will order more tests to confirm a diagnosis.
What is a transillumination?
Transillumination is a test used to identify abnormalities in an organ or body cavity. The test is performed in a dark room, with a bright light shined at a specific body part to see the structures beneath the skin. The test is simple and easy, and offers a quick way for your doctor to check your body or organs.
What is the procedure for transillumination?

Can transillumination of teeth identify fractures?
Transillumination of teeth can identify fractures, especially after restorations are removed.
What is the purpose of transillumination?
Description: Use of a high-intensity light to help define normal from abnormal structures or functions. Using transillumination, the density and composition of tissue is assessed by its diffusion of light.
What is transillumination in a dark room?
Transillumination performed in a dark room is useful for diagnosing sinusitis, especially when combined with visualization of a purulent discharge, a patient's report of a poor response to decongestants or antihistamines, a maxillary toothache, and the presence of discolored rhinorrhea (Chapter 434).
Which is more accurate, transocular or trans-scleral?
This is less convenient than transpupillary transillumination but slightly more accurate. Trans-scleral, with the light source on the sclera over the tumor. This only determines whether or not the tumor transmits light.
Can transillumination be used to locate tumor margins?
Transillumination can be used to locate tumor margins. In general, pigmented tumors and intraocular hemorrhage would block the transmission of light. It must be realized that not all pigmented tumors are melanoma and, conversely, not all melanomas are pigmented.15 Different techniques are possible ( Fig. 31.3 ).
Is transillumination a plain film x-ray?
Transillumination is still ultimately restricted not only to fairly translu cent parts of the patient body but is – resembling conventional plain-film x-ray – displaying a summation of absorption and scattering of the whole specimen diameter and is, thus, insensitive to heterogeneity within the target volume. Detailed molecular composition and changes of tissue optical density under pathological circumstances are reflected – if detectable at all – in terms of increased (or reduced) overall absorption only.
What is transillumination in medical terms?

What is the purpose of transillumination?
Transillumination. Some have suggested that transillumination be used to identify the patient with occluded sinuses. For this technique to be performed properly, the patient must be in a room that can be darkened sufficiently. The examiner's eyes must be given time to adapt to the dark environment.
Why is MRI important for sinusitis?
It is especially useful when there is concern that the patient's symptoms might be related to a tumor or that the infection has spread beyond the sinuses. It is often less accurate than CT in the preoperative evaluation of patients. Because MRI is not readily available, is time-consuming, and in young children is likely to require sedation, it is likely to be of limited benefit to emergency physicians.

Is transillumination a radiograph?
Data regarding transillumination are limited, although three studies examined in a 1993 review article discussed transillumination in adults. In each study, transillumination was compared with radiographs, with evidence of sinus disease on radiograph being considered the gold standard.

What is the best test for sinusitis?
No laboratory tests are indicated in the emergency department for acute uncomplicated sinusitis because the diagnosis is usually clinical. A plain sinus x-ray is most accurate for the maxillary, frontal, or sphenoid disease but is not useful for evaluating the anterior ethmoid cells or the ostiomeatal complex from which most sinus disease originates. Positive findings on plain films are air-fluid levels, sinus opacity, or mucosal thickening of 6 mm or more. Coronal CT at a thickness of 3 mm to 4 mm is the modality of choice. The CT findings suggestive of sinusitis are sinus opacification, air-fluid levels, sinus wall displacement, and 4 mm or greater mucosal thickening[5]. Culture and biopsy are indicated for chronic bacterial and fungal sinusitis[6].

Can you use oxymetazoline for sinusitis?
Humidification, nasal wash, decongestants (topical or systemic) such as pseudoephedrine. Remember that oxymetazoline cannot be used for more than 3 days due to rebound congestion and that oral decongestants should be used with caution in hypertensive patients. Antihistamines have not been shown to be useful and can lead to impaired drainage. They are only of benefit in early allergic sinusitis. Topical steroids are used to diminish nasal mucosal edema but are more efficacious in chronic and allergic sinusitis. Only start antibiotics if you strongly suspect bacterial disease[7].
