Oral and Maxillofacial SurgeryAppropriate surgical margin for odontogenic myxoma: a review of 12 cases
Section snippets
MATERIAL AND METHODS
We retrospectively reviewed the records of 12 patients with a histologic diagnosis of OM treated at the Department of Oral and Maxillofacial Surgery, Tokyo Medical and Dental University, between April 2001 and March 2015. Clinical, radiologic, and histopathologic findings, treatment provided, and clinical course of these patients were evaluated. Osteotomy or bone shaving with enucleation was performed with 5-mm bony margins from the radiologic extent of the tumor based on the report that a 1-cm
Clinical characteristics
Six hundred and thirty-four patients with histopathologically diagnosed odontogenic tumors were treated at our institution during the study period. OM accounted for 1.9% of all cases of odontogenic tumors treated during this time. OM cases comprised 4 men and 8 women with a median age of 41.5 (range 27–65) years at the first visit (Table 1). These patients presented from 1 month to 10 years (median 2.5 years) after they first noticed symptoms or after the lesion had been identified at another
DISCUSSION
OM is a rare benign but locally aggressive tumor of the jaw. This tumor has been reported to account for 0.5–20% of all odontogenic tumors in adults and 8.5–11.6% of those in children.1 There seems to be a regional difference in prevalence, in that OM is more common in African and Caucasian populations than in the population of the Far East.5 In this report, we describe 12 cases (1.9%) of OM out of 634 odontogenic tumors treated at our department over a period of 14 years.

2022, Annals of Medicine and SurgeryCitation Excerpt :Radical surgical resection includes a 1.5–2 cm of healthy bone margin, to reduce the risk of recurrence [7]. Some authors, however, have suggested that a margin of healthy bone tissue might not be necessary to avoid recurrence [30]. Conservative treatment by enucleation and curettage is recommended for tumors with a diameter less than 3 cm, but since myxomas are not encapsulated and tend to infiltrate the surrounding bone, a more extensive resection than curettage and peripheral osteotomy is often required for larger lesions [6,8,10].
Conservative surgical treatment of odontogenic myxoma with preservation of the inferior alveolar nerve
2022, Journal of Oral and Maxillofacial Surgery, Medicine, and PathologyCitation Excerpt :Several reports recommend radical methods that ensure a safety margin of ≥1 cm around the tumor [3,6,10,14,15]. In our previous clinical investigation of patients with OM, we observed a mean distance of 5.4 mm (range, 3.4–7.0 mm) between the tumor and the bone margin using radiographs of surgical specimen in segmental mandibulectomy cases; notably, no recurrent cases were observed [16]. Therefore, we reported that the conventional safety margin of ≥1 cm for OM, a benign tumor, might not be necessary.
Navigation-assisted transoral resection of a large maxillary odontogenic myxofibroma using rigid endoscopy
2020, Journal of Oral and Maxillofacial Surgery, Medicine, and PathologyCitation Excerpt :Clinically, odontogenic myxoma is characterized by slow growth and bony invasion, resulting in a painless facial deformity [3,8–10]. Although the only treatment available for odontogenic myxoma is surgery, there is no consensus regarding the best surgical technique for odontogenic myxoma [8,9,11,12]. This report describes the case of a 36-year-old man with a maxillary odontogenic myxofibroma that was resected transorally by navigation-assisted surgery and by using a rigid endoscopy and discusses the usefulness of this system for the surgery of maxillary benign tumors.
Primordial odontogenic tumour: A systematic review of the common but also unusual features of this novel entity
2020, Journal of Stomatology, Oral and Maxillofacial SurgeryCitation Excerpt :The aim of this systematic review is to update all available data on POT published in the literature and to identify those features of the neoplasm that require further investigation in future studies. It is fundamental that clinicians worldwide increase their awareness of the existence of this neoplasm in the pediatric population since it can be surgically enucleated without the use of more aggressive approaches, such as those required for ameloblastoma or odontogenic myxoma [8,9]. This study followed the guidelines of the PRISMA statement [10].
