Classification


Here we explain potential causes of palatal perforation and demonstrate some features.
1.Developmental:
During the sixth week of prenatal period, palatal shelve coalesce to form the hard palate. Failure to this integration results in cleft palate.(Illustration 1) Some syndromes, maternal alcohol consumption and cigarette smoking, folic acid deficiency, corticosteroid use and anticonvulsant therapy are some causative agents for this abnormality. (1)Sometimes an elderly edentoulous denture wearer complaines of a perforation in his/her palate. Due to bone resorption a previously impacted canine may emerge in the form of a palatal perforation. An orthopantomograph can easily reveal the impacted tooth.(Illustration 2)
2. Infectious:
There are some infections resulting in palatal perforation. In leprosy, tertiary syphilis, tuberculosis, rhinoscleroderma, naso-oral blastomycosis, leishmaniasis, actinomycosis, histoplasmosis, coccidiomycosis and diphtheria The palatal roof may be perforated.(2-3) (Illustration 3)
3. Autoimmune:
There are some autoimmune diseases which results in palatal perforation. Examples are lupus erythematous, sarcoidosis, Crohn's disease and Wegener granulomatosis.(4)
4. Neoplastic:
differenttumors can extend from maxillary sinus or nasal cavity and perforate the palate. Although these neoplasms usually form a mass, but in advance cases perforation of palate may occur in course of disease or following treatment(5)
5. Drug related:
palatal perforation due to cocaine abuse is a well-known situation. Other drugs (heroine, narcotics) can be responsible for palatal perforation.(6-7)(Illustration 4)
6. Iatrogenic:
Sometimes following a tooth extraction an oro-antral fistula remains.(Illustration 5). Other procedures such as tumor surgery(maxillectomy), corrective surgeries(e.g.septoplasty) or intubation can cause palatal perforation.(8)
7. Rare causes:
Rhinolithcan result in palatal perforation. Patients with psychologic problems may present with a fictitiouspalatal perforation.(Illustration 6)
