[Cyst and pseudocyst of oral maxillo-facial region. Clinical and therapeutical considerations].

Oral and maxillo-facial cysts are very common lesions that show different clinical and pathological aspects. The surgical treatment of these lesions is conditioned by many factors such as the lesion dimension, the involvement of vascular and neurological structures, the presence of recoverable teeth into the cyctic area, the conditions of the patient. For these reasons surgical treatment guidelines may greatly diverge in the various cases. There are three different kinds of treatment: cystotomy (Partsch I), cystectomy (Partsch II) and a combination of the two reported surgical treatments: at first Partsch I and in a second time Partsch II. The authors present two cases of maxillo-facial cysts that are characterized by different clinical aspects: a follicular cyst in a male, nine years old, and a retention cyst located in the tongue of a young female. Follicular cyst is a very common lesion of maxillary bones related to an impacted tooth; retention cyst is a rare soft tissue pathology. The analysis of these so different cases permits to formulate many interesting observations about the main aspects of diagnosis, treatment and management of patients affected by maxillo-facial cysts.
