This is often done with a combination of a CT scan of the sinuses without contrast and an endoscopic evaluation by an Ear Nose and Throat doctor. Once dimensions are obtained the surgeon will decide if it is possible to close the perforation. Multiple approaches to access the septum have been described in the literature. While sublabial and midfacial degloving approaches have been described, the most popular today is the rhinoplasty approach. This can include both open and closed methods. The open method results in a scar on the columella, however, it allows for more visibility to the surgeon. The closed method utilizes an incision all on the inside of the nose. The concept behind closure includes bringing together the edges of mucosa on each side of the perforation with minimal tension. An interposition graft is also often used. The interposition graft provides extended stability and also structure to the area of the perforation. Classically, a graft from the scalp utilizing temporalis fascia was used. Kridel, et al., first described the usage of acellular dermis so that no further incisions are required; they reported an excellent closure rate of over 90 percent. Overall perforation closure rates are variable and often determined by the skill of the surgeon and technique used. Often surgeons who claim a high rate of closure choose perforations that are easier to close. An open rhinoplasty approach also allows for better access to the nose to repair any concurrent nasal deformities, such as saddle nose deformity, that occur with a septal perforation.
Diagnosis
The best diagnostic tool to confirm adrenal insufficiency is the ACTH stimulation test; however, if a patient is suspected to be experiencing an acute adrenal crisis, immediate treatment with IV corticosteroids is imperative and should not be delayed for any testing, as the patients health can deteriorate rapidly and result in death without replacing the corticosteroids.Dexamethasone should be used as the corticosteroid if the plan is to do the ACTH stimulation test at a later time as it is the only corticosteroid that will not affect the test results.If not performed during crisis, then labs to be run should include: random cortisol, serum ACTH, aldosterone, renin, potassium and sodium. A CT of the adrenal glands can be used to check for structural abnormalities of the adrenal glands. An MRI of the pituitary can be used to check for structural abnormalities of the pituitary. However, in order to check the functionality of the Hypothalamic Pituitary Adrenal (HPA) Axis the entire axis must be tested by way of ACTH stimulation test, CRH stimulation test and perhaps an Insulin Tolerance Test (ITT). In order to check for Addisons Disease, the auto-immune type of primary adrenal insufficiency, labs should be drawn to check 21-hydroxylase autoantibodies.
