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.
[5] [6] The fluid is usually a clear yellow, and contains amylase (in contrast to fluid from a seroma). [6] Pressure dressings do not tend to be used. [6] They are rarely chronic, however if persistent a surgical drain may be required. [6] Botulinum toxin injections have also been used to manage this condition. [3]
commissural pits, which are small pits near the labial commissure of the mouth, [3] a pit in the upper lip, in which case it may be called a midline sinus of the upper lip, [2] and; pits in the lower lip, in which case it may be called a congenital sinus of the lower lip. [2]
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.
Sip on clear bone broth. Along with tea, sipping on clear hot bone broth can also help to moisturize your mucous membranes and promote better mucus flow, says Dr. Mercola. Broths are rich with ...
Initially, eating and drinking by mouth is not permitted and fluids are delivered intravenously for a few days. [24] Progression to a regular diet can be accomplished, starting with the consumption of clear fluids. [24] After the surgery, a tube is placed in the newly created channel to keep it open while it heals. [25]
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]
