A better understanding on the risk factors responsible for causing ORN and the underlying pathophysiology may improve our ability to prevent this complication and help to improve the prognosis for those being treated for osteoradionecrosis.

Although third molar extraction is a routinely carried out procedure in a dental set-up, yet it is feared both by the patient and the dentist due to an invariable set of complications associated with it, especially in the form of nerve injuries. Hence, prior to performing such procedures, it would be wise if the clinician thoroughly evaluates the case for any anticipated complications so that adequate preventive measures can be taken to minimize the traumatic outcomes of the procedure and provide maximum patient care, which would further save the clinician from any sort of litigation.

Malignant fibrous histiocytoma, the most frequent soft tissue sarcoma of adulthood, was first described as a new malignant tumour by O'Brian and Stout in the 1960s and the details of the histopathological features of MFH were first described by Kempson and Kyriakos. Despite the frequency of diagnosis, MFH has remained an enigma as no true cell of origin has ever been identified. Treatment consists of surgical excision and in some cases chemotherapy and radiation. Early and complete surgical removal using wide or radical resection is indicated because of the aggressive nature of the tumor. The combination of infrequent occurrence, varied pathologic features, uncertain histogenesis, numerous subtypes and the many potential sites of presentation makes these tumors a challenge for the diagnostician, surgeon and oncologist. Close follow-up after treatment is important, as local recurrence is common and early metastasis to the lungs is also frequent, which are the reasons for high mortality rate in MFH.

The collection in the maxillary sinus due to fracture of floor of orbit, blood and bony fragments collected in the maxillary sinus can be easily drained and removed after removal of anterior wall of maxillary sinus and through the same approach you can reduce the floor of orbit manually to the proper position which helps to decease the orbital floor defect.

This particular case may be the unique of its kind, as recent literature did not reveal any case where an ectopic mandibular third molar led to osteomyelitis of the condyle. Diagnosis and management in such cases deserve very special attention to rule out various local and systemic causes which can cause osteomyelitis to affect very unusual site like mandibular condyle. The aim of surgical intervention should be to cause minimum morbidity without affecting the functional efficiency of the mandibular condyle. In this report, we also have proposed the indications for surgical intervention to remove ectopically erupted teeth.
