An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum.

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.
It was described by George Caldwell in 1893 and Henry Luc in 1897. They describe the operation of maxillary sinus diseases via canine fossa. Functional endoscopic sinus surgery is the standard surgery for maxillary sinusitis nowadays. [10]
Alveolar bone grafting can also bring about the following benefits: stabilisation of the maxillary arch; aid of eruption of the canine and sometimes lateral incisor eruption; offering bony support to the teeth lying next to the cleft; elevate the alar base of the nose; aid sealing of oro-nasal fistula; permit insertion of a titanium fixture in ...
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.

In the case of a dentigerous cyst, marsupialization may be performed to allow the growing tooth associated with the cyst to continue eruption into the oral cavity. [2] It is also in use in dacryocystorhinostomy surgery in which the lacrimal sac mucosa is connected to the nasal mucosa above the level of the mechanical obstruction at the ...
