Cysts of the Oral and Maxillofacial Regions
Chapter One
Classification and Frequency of Cysts of the Oral
and Maxillofacial Tissues
Kramer (1974) has defined a cyst as 'a pathological cavity
having fluid, semifluid or gaseous contents and which is
not created by the accumulation of pus'. Most cysts, but
not all, are lined by epithelium. Cysts of the oral and maxillofacial
tissues that are not lined by epithelium are the
mucous extravasation cyst of the salivary glands, the
aneurysmal bone cyst and the solitary bone cyst. Despite
these examples, most pathologists prefer to describe those
pathological cavities not lined by epithelium as 'pseudocysts'.
Reichart and Philipsen (2004) prefer to describe
these as 'cavities' rather than cysts; hence, for example,
'aneurysmal bone cavity'. The classification proposed in
this book divides the cysts of the oral regions into those
lined by epithelium, and those that are not. Epithelial-lined
cystic odontogenic neoplasms, such as the unicystic
ameloblastoma, are not included in this edition.
