Ligature fistula

A ligature fistula is a tubular or cystic drainage channel in the oral cavity that connects a tooth to the affected root canal. This canal can cause pain and inflammation around the tooth. A fistula can be detected both during initial diagnosis by dentists and during longer observation of the patient. Treatment of a fistula involves removing the infected tooth, eliminating the root canal and any cysts or fistulas that may be caused by the infection.

Fistulas can occur for a variety of reasons, ranging from infection, improper dental implantation or heredity, to infection after botched surgery. Any interference with the root system of the tooth will create potential risks for the development of fistulas. They also appear in children when teeth

Ligature fistula - (lat. fistula labialis) belongs to the category of diseases accompanied by the formation of pathological pathways that ensure the outflow of the contents of the oral cavity and nose into the oral cavity.

Ligature fistulas are formed more often after tooth extraction in up to six months. When pus or discharge accumulates in a non-expandable canal, it is possible to create access to the tooth cavity (as far as possible) and eliminate the inflammatory process. Then, by applying filler to the cyst and wedging it into the bone tissue, the formation of a fistula begins, which is called a ligature fistula.

In this case, muscle tissue and fascia are briefly involved in the pathological process. The cavity gradually expands. The pathological process of ligature fistulas tends to self-destruct. As the size of the external tract increases, bone tissue resorption occurs. Their mass decreases, after which the stroke volume returns to its original value. This characterizes the relative stability of the foci of formation of “internal fistulas”.

As a result of the inflammatory process occurring against the background of teething, proliferation of the mucous membrane and hardening of the formed bone tissue of the interradicular partitions of the canals, as well as at the level of the frontal part of the teeth, deterioration of oxygenation of the bone marrow and myelin fibers in the epileptic sutures occurs. Inflammation of the periapical tissues develops, which is complicated by suppuration. This can lead to a local or systemic pathological process due to disruption of the blood supply to the alveolar vessels.
