Cysts of the Oro-Facial region: A clinico-pathologic review of 403 Nigerian cases
Abstract
Objectives: To review the types, frequency, distribution, treatment, and treatment outcome oforo-facial cysts seen at four tertiary health centres in southwestern Nigeria and to categorise the cases using Lucas (1966), Killey and Kay (1968) and World Health Organization (WHO) (2005) classification protocols.
Design: A decriptive retrospective study
Setting: Tertiary hospitals across the south west zone of Nigeria.
Main outcome measures: Treatment outcome of oro-facial cysts seen at four tertiary health centres in southwestern Nigeria and categorisation of the cases using Lucas (1966), Killey and Kay (1968) and World Health Organization (WHO) (2005) classification protocols.
Results: The treatment modalities included marsupialisation, enucleation, enucleation with peripheral osteotomy and surgical excision of non-epithelial cyst of the jaws. The follow-up period ranged from a minimum of six month to five years. Such follow-up consisted of examination and periapical or panoramic radiographs. All patients were without evidence of disease during the follow-up period and many of them were lost to follow up due to absence of diseased condition. Lucas classification and WHO classification showed that inflammatory cysts were the most common accounting for 36%, developmental cysts represented 27%, 4% were non-epithelial while, 32.8% were unclassifiable.
Conclusion: The inflammatory jaw cyst is the most common type in southwest Nigeria, occurs more in males compared to females and is more common in the mandible compared to the maxilla.
