OBJECTIVE: The purpose of this study was to report our
experience with surgical treatment of 31 mandibular odontogenic
keratocysts, with special reference to their recurrence, and to
review the literature on this subject.
STUDY DESIGN: A retrospective analysis was conducted of
all odontogenic cysts treated in the Department of Oral Surgery
and Oral Medicine at Jordan University of Science and Technology
between 1989 and 1995. Of a total of 227 odontogenic cysts, 31
odontogenic keratocysts were histopathologically diagnosed
preoperatively. They were surgically treated through an
intraoral approach by resection without continuity defects. The
lower border of the mandible and/or the posterior border of the
ramus was left intact. In cases where teeth were in continuity
with the lesion, they were extracted. In cases where cortical
perforation occurred, any associated overlying mucoperiosteum
was excised. All patients were reviewed annually for a follow-up
period of 2 to 8 years.
RESULTS: All odontogenic keratocysts were found in the
mandible. Of these, 23 were in the ramus and angular region
(74.2%) and 8 were located in the body of the mandible. No
recurrences of the operated odontogenic keratocysts were
observed during the follow-up period.
CONCLUSION: Our findings indicate that removal of
odontogenic keratocysts by resection without continuity defects
is a satisfactory method of treatment. [References: 47]
