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.
Luma Wire Transillumination: This technique has a number of advantages [19] over antral Lavage, such as: 1) Discovery of the location of the Maxillary Sinus with greater accuracy. 2) A general improvement in safety of the procedure. 3) The ability to obtain cultures at the time of lavage, when clinically warranted or indicated by CT-scan evidence.
Also, surgical procedures with chronic sinus infections are now changing with the direct removal of the mucus, which is loaded with toxins from the inflammatory cells [citation needed], rather than the inflamed tissue during surgery. Leaving the mucus behind might predispose early recurrence of the chronic sinus infection.
In some types of fistulae, a seton may be tied with more tension and tightened periodically. In this case, the seton loop will slowly cut through tissue inside the loop while scarring behind the loop, essentially "pulling out" the fistula without surgery. This is the Kshar-Sutra method mentioned by Sushruta in ancient Indian surgical practice.
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 ...
Crown lengthening is a technique for increasing crown height of teeth by flap surgery with or without bone surgery. [3] There are two main types: Aesthetic crown lengthening which is performed when a "gummy" smile is an issue for the patient [3] Functional crown lengthening is used to make an unrestorable tooth restorable.
A tracheo-esophageal puncture (or tracheoesophageal puncture) is a surgically created hole between the trachea (windpipe) and the esophagus (food pipe) in a person who has had a total laryngectomy, a surgery where the larynx (voice box) is removed. The purpose of the puncture is to restore a person’s ability to speak after the vocal cords ...
