Extended Total Temporomandibular Joint Replacement - A Feasible Option for Functional and Aesthetic Reconstruction of Mandibular Defects Involving the Temporomandibular Joint.

Retrospective case series. Alloplastic temporomandibular joint replacement has been established as a standard technique for end- stage temporomandibular (TMJ) pathologies. Joint replacement when there are extensive mandibular defects remains a challenging clinical problem.

Silent sinus syndrome.

Silent sinus syndrome is defined as a spontaneous and progressive enophthalmos and hypoglobus with hypoplasia of the maxillary sinus and resorption of the orbital floor. It is caused by atelectasis of the maxillary sinus in the presence of ipsilateral chronic hypoventilation of the sinus. The problem may be idiopathic, but the term is now also used to describe cases that follow operation or trauma.

Mandibular fractures that have healed are not weakened permanently: series of nine patients who sustained mandibular fractures at different sites on two separate occasions.

Some patients are concerned that after satisfactory healing of a mandibular fracture the jaw will be weaker than it was before the injury, and will break readily at the same site after relatively minor injury. We aimed to find out if these concerns have any basis, and report the pattern of fracture in a series of nine patients who had sustained fractures of the jaw on two separate occasions. All fractures were at different sites from the original ones, and in only one case was the fracture adjacent to plates that had been placed previously.

A case of facial lymphoma mimicking dental infection.

Unlabelled: Infective and neoplastic swellings of the face are common. Often, the differential diagnosis is obvious, but sometimes it can be difficult to ascertain. We report the case of a cheek swelling thought to be infective in origin, but this unusual lesion turned out to be a diffuse large B-cell lymphoma.
