What is a fistula and a sinus? A fistula is an abnormal channel leading between two cavities or surfaces which may drain a fluid material such as saliva or pus. An example would be from the mouth (oral cavity) to the skin surface, usually of the face or neck, and this specific type is called an orocutaneous fistula.

fistula is defined as “an abnormal communication pathway between two internal organs or from one epithelial lined surface to another epithelial-lined surface; it is not a sinus tract.”

A fistula is an abnormal passage between a hollow organ and the skin surface, or between two hollow organs¹. “A wound sinus is a discharging bli nd-ended tract that extends from the surface of an organ to an underlying area or abscess cavity”. The cause of a sinus must always be determined by in-depth assessment.

Oroantral fistula (OAF), an unnatural communication between the oral cavity and maxillary sinus with epithelialization in the fistula tract, is among the most common causes of CMSDO, accounting for approximately 60% of odontogenic sinusitis cases [4,5].

Oro-antral communication and fistula can occur as a result of inadequate and improper treatment. Inadvertent communication with the maxillary sinus can occur during certain surgical procedures in the maxillary posterior region.

2023年12月20日 · The primary difference between the two is the number of anatomic spaces or openings involved. There is often confusion regarding the lining of a sinus tract and of a fistula. This article will review the clinical and histological features of …

2020年8月6日 · A fistula is a communication between two epithelialized surfaces – usually between one hollow viscus and another or between a viscus and the skin. A sinus is an abnormal blind‐ending track which communicates with the skin. IN this chapter we describe urological fistulas and sinuses.

2018年8月29日 · There are three types of fistulas: blind, or sinus tracts (with only one open end), complete (with both external and internal openings) and incomplete (with an external skin opening, which does not connect to any internal organ).

Sinus fistula repair is a surgical procedure aimed at closing abnormal connections between the sinus cavity and the skin surface. This condition can lead to recurrent infections and discomfort, making surgery the most effective treatment option.

2024年3月29日 · A fistula is an abnormal connection between two body parts, such as organs or vessels, that normally do not connect, while a sinus is a cavity, channel, or passageway that is intended to drain fluid or pus, often leading to or from an area of infection.
