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.
For example, the Valsalva maneuver (phase II) increases the intensity of hypertrophic cardiomyopathy murmurs, namely those of dynamic subvalvular left ventricular outflow obstruction. This is due to the decreased preload in this phase, worsening the obstruction and thus accentuating the murmur. [ 3 ]
The approach is mainly from the anterior wall of the maxilla bone. It was introduced by George Caldwell (1893)and Henry Luc (1897). The maxillary sinus is entered from two separate openings, one in the canine fossa to gain access to the antrum and other in the naso antral wall for drainage. [1]
Oro-antral fistula if associated with sinusitis. [7] Acute Bacterial Rhinosinusitis. Though it is indicated only in severe cases not as a regular treatment. [8] It can be also used as diagnostic procedure for: Carrying out culture and sensitivity test if the returning fluid is mucopurulent or purulent in Chronic Sinusitis. [9]
Alveolar cleft grafting is used primarily to allow the eruption of the maxillary canines into the mouth between the ages of 8 and 13 years old. It is also used to close oranasal fistulas, stop fluid reflux into the nose, improve speech, support the maxillary lateral teeth, and stabilize the jaw for orthodontics or orthognathic surgery.
Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
Negative pressure wound therapy device. Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
Advanced airway management is the subset of airway management that involves advanced training, skill, and invasiveness.It encompasses various techniques performed to create an open or patent airway – a clear path between a patient's lungs and the outside world.
