Surgical treatment of nasopalatine duct cysts. A follow-up study.
In a clinical-radiological study, 43 operated and histopathologically verified incisive canal cysts were subjected to follow-up investigation. The clinical investigation revealed no subjective symptoms. Abnormalities of the sensibility to the anterior part of the palate were noted in four cases, hyposensibility in three cases and hypersensibility in the fourth. The radiological investigation showed that bone regeneration occurred 1 year postoperatively at the earliest. After 3 years, two-thirds of the patients showed complete bone regeneration. Large cysts (diameter greater than 10 mm) showed the same tendency for bone regeneration as small cysts. The five patients in whom no bone regeneration had occurred were subjected to reoperation. The histologic investigation of these patients revealed scar tissue.
