“…In the case of lesions over 30 mm in size, with the displacement of adjacent structures or with buccal/lingual bone plate perforation (7-9), surgical decompression with or without extraction of the causal tooth is recommended. Surgical decompression was described by Brondum et al (12) as an alternative to the enucleation of large cysts, without the need for extensive mandibular resections. Some authors such as August et al (18) consider surgical decompression to favor a change in the histological architecture of KOTs, lessening their tendency towards recurrence.…”

“…The decrease in intracyst pressure achieved with surgical decompression allows a reduction in lesion volume and favors bone growth (12,18,19). This technique also affords information on the histological type of OC involved (12,18,19).…”

“…This technique also affords information on the histological type of OC involved (12,18,19). Surgical decompression moreover considerably reduces complications such as mandibular fracture, oroantral fistulas or damage to nerve structures (12,18,19). However, decompression has two important disadvantages.…”

Objectives: To determine the relative incidence of odontogenic cysts and to identify the main clinicopathological features among patients treated in the Oral Surgery Department of the Dental Clinic of the University of Barcelona (Spain). Study design: A retrospective observational study was made of 418 odontogenic cysts diagnosed in 380 patients included in the database of 1235 histopathological diagnoses. The subjects were treated in the Master degree program of Oral Surgery and Implantology of the University of Barcelona in the period 1997-2006. The following variables were recorded: gender, age, clinical characteristics of the lesions (size and location), radiological features, duration, treatment, complications and relapses. A descriptive analysis was made of the study variables, using the SPSS version 15.0. Results: The incidence of odontogenic cysts was 33.8%. The mean patient age at appearance of the lesion was 42 years (range 7-83). The cysts were slightly more prevalent in males (58.4%). The lesion size ranged from 2-60 mm, with a mean size of 18.4 mm. The most frequent diagnosis was radicular cyst (50.2%). The most common location of the odontogenic cysts was in the mandible (61.5%), particularly the lower third molar region (36.8%). Conclusions: The most frequently diagnosed lesion was the radicular cyst. Odontogenic cysts were seen to be slightly more prevalent in males, and showed a high mandibular incidence. Knowledge of the biological and histological behavior of odontogenic cysts and their frequency are key aspects for ensuring early detection and adequate treatment.

“…No recurrence was seen in the follow-ups in the first year. Brondum and Jensen [4] found 3% likelihood of recurrence in the first year following the operation. Forssell et al [8] also reached similar conclusions.…”

“…This rare lesion is significant due to its clinically and pathologically uncommon growth pattern and its high recurrence rate. [4] Recurrence is mostly seen within the first five years after the treatment. Recurrence rates can be as high as 62%.…”
