Oral and maxillofacial surgery requires an extensive 4-6 year surgical residency training covering the U.S. specialty's scope of practice: surgery of the oral cavity, dental implant surgery, dentoalveolar surgery, surgery of the temporomandibular joint, general surgery, reconstructive surgery of the face, head and neck, mouth, and jaws, facial ...
Although it was originally postulated that the cyst formed from trapped epithelial cells during embryonic fusion of the palatal bones, [3] it is now thought that it forms from oronasal ducts present within the incisive canals. [4] [5] As a cyst, the nasopalatine duct cyst requires histological analysis for a definitive diagnosis.

Recurrence is likely when treated by simple enucleation. Contributing causes include thin and fragile epithelium leading to incomplete removal, cyst extensions extending into cancellous bone, satellite cysts found in the wall, experience of the surgeon, formation of further new cysts from other remnants of the dental epithelium.
About 90% of pilar cysts occur on the scalp, with the remaining sometimes occurring on the face, trunk, and extremities. [7]: 1477 Pilar cysts are significantly more common in females, and a tendency to develop these cysts is often inherited in an autosomal dominant pattern. [7]: 1477 In most cases, multiple pilar cysts appear at once.
Symptomatic (producing or showing symptoms) cysts may require surgical removal if they are present in areas where brain damage is unavoidable, or if they produce chronic symptoms disruptive to the quality of life of the patient. Some examples of cyst removal procedures include: permanent drainage, fenestration, and endoscopic cyst fenestration. [3]
A ganglion cyst is a fluid-filled bump associated with a joint or tendon sheath. [3] It most often occurs at the back of the wrist , followed by the front of the wrist. [ 3 ] [ 4 ]
Treatment to remove these tumors always involve radical surgery. The reported recurrence rate for a subtotal removal is 30% after a mean interval period of 8.1 years. [4] Surgery is the primary treatment for removal of the brain tumor. Use of an endoscope may assist on obtaining a more complete surgical removal from hidden recesses. [5]
