Cystic lesions of the jaws: a retrospective clinicopathologic study of 2030 cases

A retrospective multicentre study of cystic lesions and odontogenic tumours in older people

“…There are a variety of cysts in the oral and maxillofacial region which are classified into non‐odontogenic cysts, inflammatory odontogenic cysts, developmental odontogenic cysts and lesions that are not true cysts despite clinical similarity, denominated pseudocysts . In the present study, the incidence of odontogenic cysts was six times higher than that of non‐odontogenic cysts, in agreement with previous studies conducted on the general population …”

“…In our analysis, salivary duct cyst was the most frequent lesion in this group, followed by nasopalatine duct cyst. This finding differs from previous studies on general and elderly populations, where nasopalatine duct cyst was the most prevalent cyst . Regarding the anatomical location, most intraosseous cases occurred in the maxilla, in agreement with other studies, while in soft tissues, the lip, floor of the mouth and buccal mucosa were the most frequent sites .…”

“…Although non‐odontogenic cysts were uncommon, according to some authors, these are unusual lesions in all age groups . In our analysis, salivary duct cyst was the most frequent lesion in this group, followed by nasopalatine duct cyst.…”

“…Several studies have reported the prevalence and incidence of cystic lesions and odontogenic tumours in the maxillofacial complex. Nonetheless, few of them have characterised the lesions according to age group . This type of analysis facilitates the understanding of the features inherent to each age, considering that humans present physiological changes in each phase of life that guide the treatment and prognosis of the diseases.…”

Epidermal inclusion cyst of the maxillofacial region

“…Oral and pharyngeal epidermoid cysts of the inclusion cyst variety also occur, but are rare in adults and are frequently so small that they are not biopsied. Syndromes associated with multiple cutaneous epidermoid cysts, such as Gardner syndrome, Gorlin syndrome and pachyonychia congenita [12], do not demonstrate cysts of the oral mucosa, but facial cysts may occur. Epidemiologic investigation has determined a prevalence rate of 1 cyst per 2,000 adults.…”
