CT of intact but nonfunctioning temporomandibular joints following temporal bone fracture.

Six patients were examined by CT following head trauma, with bleeding from the ear and trismus. The mandibular condyles were normal and MRI in two patients demonstrated a normally located meniscus. An unilateral comminuted temporal bone fracture (TBF) with multiple fracture lines and one or more fragments detached from the petrous bone was demonstrated by CT in every patient. On physical examination there was trismus, inability to chew and local pain in the temporomandibular joint (TMJ) without tenderness and swelling. Measurements of vertical and horizontal mandibular movement unequivocally demonstrated TMJ malfunction in comparison with 10 controls. The malfunction was presumably due to instability of the fractured petrous bone, base of the TMJ. Immobilising one TMJ results in blocking of both joints. Clinical improvement in 6-8 months and absence of symptoms of joint derangement on repeated physical examination were thought to be explained by restored petrous bone stability following healing of the fractures. The phenomenon of trismus following TBF with normal TMJ is rare and not yet reported.

Primary Ewing's sarcoma of the temporal bone.

Primary cranial Ewing's sarcoma is exceptionally rare. Only ten cases of such a tumor had been reported heretofore in the literature. We describe a case of primary Ewing's sarcoma occurring in the temporal bone. The tumor was surgically excised, and the patient underwent radiation and chemotherapy. Neither recurrence nor distant metastasis was noted at 12 months after surgery. Although the prognosis of Ewing's sarcoma in general is often poor because of early metastasis to the lungs and/or to other bones, a review of the literature suggested that the same tumor occurring in the cranium can often be successfully managed by intensive therapy with radical excision and radiochemotherapy. This inference was supported by the case reported here.

Rheumatoid nodule of the temporal bone.

A 69-year-old woman with severe rheumatoid arthritis presented with a history of chronic otitis and a facial nerve paralysis. She was found to have a rheumatoid nodule involving the mastoid and mesotympanum. This is believed to be the first reported case of a rheumatoid nodule involving the temporal bone.

Cryptococcal infection of the temporal bone.

Cryptococcus neoformans is a yeast-like organism which, after inhalation, may cause pulmonary disease or a systemic fungemia associated with numerous extrapulmonary sites of infection, but most notably affecting the central nervous system. Despite this frequent involvement of the leptomeninges, only three cases of infection of the temporal bones have been previously described. We describe an additional case with comments on the possible significance of infection of this site.

Electrophysiologic monitoring of facial nerve during temporal bone surgery.

Monitoring of peripheral nerves during surgical procedures decreases trauma to the nerve, which may preserve function. During 1984, electrophysiologic monitoring of the facial nerve was used during 32 operative procedures in and around the temporal bone. The largest group were for cerebellopontine angle tumors. Clinically, monitoring appeared to be helpful by providing objective evidence of trauma to the facial nerve and a method of demonstrating integrity of the nerve. However, review of this series did not reveal objective evidence of improved facial nerve preservation compared to results in a similar group of patients operated on without monitoring. We think that the monitoring is best done by personnel experienced with the technique.

Cerebrospinal fluid fistula: the identification and management in pediatric temporal bone fractures.

Cerebrospinal fluid (CSF) fistula represents a potentially lethal complication and requires a high index of suspicion to make the diagnosis. A 12-year retrospective study of pediatric basilar skull fractures identified 147 patients with temporal bone fractures, of which 37 patients exhibited evidence of CSF fistula. The diagnosis is made from a combination of clinical, radiographic, and chemical evaluation. The evolution of diagnostic techniques are reviewed, and the more recent and sensitive tests, such as beta-2 transferrin, are emphasized. Treatment of CSF fistula is nonsurgical in most cases. Surgical exploration and mastoid obliteration were required in two patients, and the indications for surgical treatment are explored. The use of antibiotic prophylaxis is controversial and not routinely indicated.

Juvenile xanthogranuloma of temporal bone--a case report.

Juvenile xanthogranuloma is an unusual condition of childhood. It commonly presents as cutaneous lesions normally localized to the dermis and is benign. A case report of a two-year-old girl with juvenile xanthogranuloma involving the right temporal bone (petro-mastoid region) which was locally destructive, is presented.

Temporal bone pathology of leukemia and malignant lymphoma with middle ear effusion.

This report describes the histopathological findings of the middle ear in patients with leukemia and malignant lymphoma whose middle ear effusion (MEE) was observed from temporal bone specimens. There were 19 patients (35 ears) with leukemia and 8 patients (16 ears) with malignant lymphoma. MEE was observed in 8 of 35 ears with leukemia, and 5 of 16 ears with malignant lymphoma. In 8 ears with leukemia with MEE, pathological changes included effusion containing floating tumor cells in 4 and tumor infiltration around the Eustachian tube in 3. In 1 of 5 ears with malignant lymphoma with MEE, MEE was accompanied by tumor infiltration. Infection was present in 13 ears of patients with leukemia and malignant lymphoma. It is suggested that there are various causes, including infection, obstruction of the Eustachian tube with tumor infiltration and a tendency to bleed, of MEE in leukemia and malignant lymphoma.

MR imaging of facial nerve enhancement in Bell palsy or after temporal bone surgery.

The authors evaluated magnetic resonance (MR) images obtained with intravenously administered gadolinium in ten patients who had facial paralysis and no facial nerve tumor. In patients with either Bell palsy (four patients) or facial paralysis after temporal bone surgery (six patients), intratemporal facial nerve enhancement was seen. Facial nerve enhancement on MR images proved to be a nonspecific finding.
