“…Although OM is a benign tumor, radical treatment is needed because the rate of local recurrence ranges from 10% - 33% [3-5]. Surgical resection with a minimum bone margin of 1 cm has been advocated [6-9], but emerging evidence suggests that a more conservative surgical approach will result in acceptable recurrence rates with less patient morbidity if follow-up can be over the long term [7, 10-12]. However, little has been reported about the actual long-term follow-up of patients with OM after conservative surgery.…”

Odontogenic myxoma (OM) is a relatively rare, benign odontogenic tumor with locally aggressive behavior, but it is a nonmetastasizing neoplasm of the jaw bones. Although radical resection with an appropriate surgical margin is recommended, emerging evidence has suggested that a more conservative approach will result in acceptable recurrence rates with less morbidity if careful long-term follow-up is provided. A 56-year-old Japanese man with odontogenic myxoma of the left mandible was conservatively treated by surgical enucleation and curettage because he desired functional and cosmetic preservation. During a follow-up period of 100 months, the patient has remained clinically and radiologically free of recurrence. As far as we can ascertain, 20 reports published after 1990 described 37 patients with mandibular OM that had been treated by conservative surgery. Tumors recurred during a mean follow-up of 49.2±42.8 months in 7 (18.9%) patients, and only one of five patients who were followed up for over 100 months developed recurrence. The rate of recurrence decreased from 24.0% to 8.3% when follow-up exceeded 60 months. Although enucleation and curettage have proven effective, the risk of recurrence remains considerable and long-term follow-up is indispensable. More evidence of long-term outcomes after conservative surgery for OM is needed.

“…Recently, Zanetti, et al strongly suggested conservative treatment should involve enucleation of the lesion with a wide curettage of normal tissue or a generous amount of apparently uninvolved surrounding tissue, or even peripheral osteotomy, as this has the advantage of preserving vital structures and maintaining oral function [24].…”

mor, incidence rate is approximately 0.07 new cases per million people per year [7,8].All reports generally agree that the tumour frequently presents in the second or third decades of life [8][9][10].Most common clinical characteristics of odontogenic myxoma are swelling of the jaws with only few patients complaining of pain, paraesthesia and ulceration, 28% for pain and 56% for swelling [11].Several studies indicating that there is a higher rate of tumour incidence in the mandible than the maxilla [12][13][14][15], and almost occurring in the premolar and molar region of both jaws and rarely crosses the midline [12,16,17].Cortical expansion and perforation are common findings; however, maxillary myxomas often extend into the sinus [18]. The adequate management of Odontogenic myxoma (OM) is a challenging problem against the high risk of recurrence.The aim of this paper is to report a case of odontogenic myxoma that affected the left maxilla focusing especially on surgical management. Case ReportA 42-year-old female was referred to our department with a complaint of a growing swelling in the area of the canin and premolar molar in his left maxilla that had been noticed a few weeks before. Upon admission, she noticed a swelling measuring about the size of a peanut in the gingiva of upper premolar tooth. That lesion had been excised by a dentist and the histopathologist con- AbstractOdontogenic myxoma (OM) is a benign, locally invasive and aggressive, non-metastasizing neoplasm of the jaw bones. This article presents a rare case of odontogenic myxoma occurring in the maxilla of a 42-year-old female patient with review of the literature emphasizing a huge controversy regarding the surgical management.

“…The above case illustrates the merits of a less than fully radical approach to treatment. In the absence of an evidence-based solution, it is best to follow Zanetti et al in using a conservative approach initially and progressing to peripheral osteotomy if recurrence occurs 11. Resections could perhaps be attempted following a recurrence subsequent to a conservative surgery.…”

Odontogenic myxomas: what is the ideal treatment?

There is no consensus regarding the ideal treatment for odontogenic myxomas, an odontogenic mesenchymal neoplasm. Various authors have suggested en bloc resection due to a concern regarding inadequate clearance while others have suggested more conservative treatment. We present a case managed by buccal cortical resection and an iliac crest bone graft. The patient had no recurrence for over 7 years.
