Osteoma of the mandibular coronoid process. Report of a case

Pseudo-ankylosis caused by osteoma of the coronoid process

Osteoma of the coronoid process is a rare, slow-growing tumor that can lead to restrictive mandibular movements. This paper describes a case of osteoma of the right coronoid process in a 45-year-old woman who reported progressive facial asymmetry and the loss of mandibular movements. Aspects regarding the differential diagnosis, treatment, surgical access, possible complications and postoperative follow up of the case are also discussed. The osteoma of the coronoid process is a benign tumor that can reach a significant size, causing an increase in volume, facial asymmetry, limited mouth opening and fracture of the zygomatic complex in some cases. The combination of extraoral and intraoral accesses is useful in the case of large tumors of difficult access, such as in this case reported.

An unusual cause for trismus caused by mandibular coronoid osteoma: a case report

Osteoma is a dense bony proliferation of otherwise normal membranous bone. This tumor is essentially restricted to the craniofacial skeleton and is rarely diagnosed in other bones. The mandible and the paranasal sinuses are the most common sites, while the involvement of the coronoid process has been reported in only 6 cases so far. This report demonstrated a case of osteoma occurring at the mandibular coronoid process in a 26-year-old female patient. The patient was managed with surgical resection of the osteoma followed by physiotherapy.

Peripheral osteoma of the maxillofacial region diagnosis and management: a study of 06 cases

BACKGROUND

Osteomas are benign neoplasm often associated with facial asymmetry, pain and surface ulceration. Peripheral osteomas are more common in the cranio-maxillofacial region. It is prevalent at younger age but maximum seen in the sixth decade, with a female to male ratio is 1:2. The aim of this study was to review the clinical presentations and management protocol of such lesions in cranio-maxillofacial region.

MATERIALS AND METHODS

The study was conducted at Command Military Dental Centre (EC) during May 2004 to May 2007. Six serving soldiers and their families (four males, two females), age group ranging between 13 and 56 years, mean age 34.5 years were recruited in this study. The tumors were excised using extra oral, intra oral and combined approaches; no complications were reported during post op period.

RESULTS

All the cases were operated under GA through extra oral, intra oral and combined approaches with satisfactory results. HPE report was benign in all our cases with no post operative complications reported during follow up.

CONCLUSION

Cranio-maxillofacial osteomas are exclusively benign tumors and not very common entities. Proper diagnosis and precision management alleviates symptoms without any post surgical complications. In our series of six cases the tumors were diagnosed and managed as per standard surgical protocol with excellent result.

Peripheral osteoma of the mandible: case report and review of the literature

BACKGROUND

Osteoma is a benign often asymptomatic neoplasm, consisting of well-differentiated mature bone. This paper reports a case of peripheral osteoma located in the anterior mandibular region and provides a review of the literature about this lesion in the jaws.

PATIENT AND METHODS

A 43-year-old white woman presented with a swelling in the left mandible of 7 years duration. The English literature was reviewed over the past 76 years and data about location, histopathology and number of the peripheral osteomas, sex, and age of the patients were evaluated.

RESULTS

Data analysis showed 69 well-documented cases of peripheral osteoma. Peripheral osteomas are more frequent in the mandible than the maxilla and the cancellous type was most frequent; males and females are equally affected in the mandible; the age range was 9-85 years.

CONCLUSION

The peripheral type of osteoma is most common in the lower jaws, occurs at the surface of the cortical bone and is sessile or pedicled.

Osteoma of the zygomatic arch--report of a case

An osteoma of the zygomatic arch in a 55-year-old woman is reported. Surgical resection through a preauricular incision was easily performed. The lesion was very large, but pedicled.
