An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar ) which is closely related to the antral floor.
A modification obturator may be used in the short term to block a palatal fistula, for augmentation of the seal and to separate the oral and nasal cavities. An interim palatal obturator is used post-palatal surgery. This obturator aids in closing the remaining fistula and is used when no further surgical procedures are planned.
Fistulectomy is a surgical procedure where a surgeon completely removes a fistula, an abnormal tract (i.e. tube) that connects two hollow spaces of the body. [1] [2] In comparison to other procedural options of treating fistulae such as fistulotomies, where a fistula is cut open (i.e. unroofed) but not completely removed, and seton placement, where a rubber band seton is passed through the ...
In anatomy, a fistula (pl.: fistulas or fistulae /-l i,-l aɪ /; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other.
The fistula can communicate with the mouth (usually causing no symptoms), the paranasal sinuses (giving rhinorrhea) [1] or the facial skin (causing saliva to drain onto the skin). The usual cause is trauma, however salivary fistula can occur as a complication of surgery, or if the duct becomes obstructed with a calculus. [1]
In cleft palate patients bone grafting during the mixed dentition has been widely accepted since the mid-1960s. The goals of surgery are to stabilize the maxilla, facilitate the healthy eruption of teeth that are adjacent the cleft, improving the esthetics of the base of the nose, create a bone base for dental implants, and to close any oro-nasal fistulas.
Fibrous hyperplasia around a dental implant, caused by a broken denture clasp. [7] The cause is usually pressure from the flange of a denture which causes chronic irritation and a hyperplastic response in the soft tissues. [6] Women during pregnancy can also present with an epulis, which will resolve after birth.
Commonly known as a dental cyst, the periapical cyst is the most common odontogenic cyst. It may develop rapidly from a periapical granuloma , as a consequence of untreated chronic periapical periodontitis .
