Abstract
The surgical removal of the wisdom teeth is obligate when forceps extraction fails or when the wisdom teeth are impacted. The surgical removal of impacted maxillary third molars is a commonly performed procedure usually associated with few
complications
& little morbidity. The most frequent complications are tooth root fracture, maxillary tuberosity fracture, tooth displacement into the maxillary sinus & oroantral fistula formation. A rarely reported complication in the displacement of a tooth
into the
infratemporal fossa.
The method of prevention of this complication is by the placement of either a finger or periosteal elevator posterior to the tooth during extraction. To remove the disploaced upper third molar is very difficult & has many complications, e.g.,
persistent
bleeding & nerve damage.
When the wisdom teeth is displaced, it is initially necessary to gain access to bone by developing a mucoperiosteal flap. Adequate access to the tooth is then achieved by conservative removal of bone. Finally, an unimpeded path of delivery is
developed
by additional bone removal or, preferably planned sectioning of the tooth, There are many approaching techniques to remove the displaced upper third molar.
This following report describes the surgical technique of displaced upper third molar in the pterygopalatine fossa by the midpalatal & transpharyngeal approach.
