<\/span><\/h2>\nA fistula is an abnormal channel that leads between two cavities or surfaces that can drain a fluid material such as saliva or pus. An example would be from the mouth (oral cavity) to the surface of the skin, usually the face or neck, and this specific type is called an orocutaneous fistula.<\/p>\n
One sinus has an open draining end and the channel ends in a blind end. An example would be a dental drain from a dental sinus. abscess<\/span> either inside the mouth or on the skin.<\/p>\nHowever, the words are often used interchangeably.<\/p>\n
<\/span>\nfistulas<\/span> and sinuses for the neck and face: classification<\/span><\/h2>\nFistulas and paranasal sinuses of the neck and face can be classified by cause.<\/p>\n
<\/span>Developmental<\/span><\/h3>\nFistulas and sinuses due to developmental causes are usually present at birth.<\/p>\n
\n- thyroglossal duct cyst<\/span> \u2013 The most common development cyst in the neck. The cyst characteristically moves upwards when the tongue is stuck out or when swallowing. It may burst to form a sinus that usually opens just below the hyoid bone at the middle line<\/span> from the neck Drains bugger<\/span>. Treatment is surgical (Sistrunk procedure) but 10% recurs.<\/li>\n
- Branchial cleft<\/span> cystside<\/span> branchial arch cyst): the most common developmental cyst on the side of the neck. A sinus may drain mucus or pus after an abscess ruptures. It usually opens on the side of the neck, just above the junction of the clavicle and breastbone (sternoclavicular joint), in front of the sternocleidomastoid muscle. There may also be an associated sinus that drains into the pharynx.<\/li>\n
- Preauricular fossae and paranasal sinuses: These are common and affect the 1% population, especially Asians and blacks. 25% are bilateral<\/span> in front of both ears The sinus opening (pit) is usually located just in front of the top of the ear, where the ear rim cartilage (helix) meets the facial skin. Are asymptomatic<\/span> unless infected (rare), when they turn red, they hurt and may download<\/span> pus.<\/li>\n<\/ul>\n\n

<\/span>How is a fistula or sinus diagnosed?<\/span><\/h2>\nIn addition to a careful history and examination, one or more of the following tests will usually be required to confirm the diagnosis and determine the cause:<\/p>\n
\n- passing a probe in the channel<\/li>\n
- radiology: may include plain x-rays, x-rays with contrast medium, Connecticut<\/span> or Magnetic resonance<\/span> scans<\/li>\n
