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.
Oral–antral communication [ edit ] A variant of the Valsalva maneuver is used to aid diagnosis of oral–antral communication, i.e., the existence of a connection between the oral cavity and the maxillary sinus .
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.
The advantage of this technique is that the entire posterior pharyngeal wall can be visualized. Disadvantages include the following: 1. This procedure requires radiation, which is a particular concern for children. 2. It is not well tolerated by some children because it requires injection of barium into the nasopharynx through a nasal catheter. 3.
The patient’s pattern of VP closure is one aspect that is taken take into consideration by doctors in deciding whether pharyngeal flap surgery is the appropriate method of treatment (Armour et al., 2005). A variety of closure patterns have been found, and the pattern varies person to person.
The surgical procedure involves closure of the nasal cavity affected with atrophic rhinitis by creating mucocutaneous flaps. [3] These flaps are sutured together in two layers: first the mucosal layer, then the skin layer. The nasal cavity is kept closed for a period of 6 months/each; then an examination is done - if the crusts have disappeared ...
Antral lavage is a largely obsolete [citation needed] surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. [1] It is also called proof puncture, as the presence of an infection can be proven during the procedure.
Possible treatment options include speech therapy, prosthetics, augmentation of the posterior pharyngeal wall, lengthening of the palate, and surgical procedures. [ 10 ] Submucous cleft palate can also occur, which is a cleft of the soft palate with a split uvula , a furrow along the midline of the soft palate, and a notch in the back margin of ...
