Baseline and follow-up MRI of the internal auditory canal after suboccipital resection of acoustic schwannoma: appearances and clinical correlations.

Prospective baseline MRI was obtained on 31 patients who had "total" removal of acoustic schwannoma 6 months to 9 years previously. Follow-up MRI was performed after 1-2 years on patients with questionable abnormalities. We found four patterns (1) internal auditory canals (IAC) with nonenhancing soft-tissue strands, possibly scars or distorted residual nerves (8); (2) IAC with marginal enhancement-reactive dura mater (16); (3) IAC with contrast-enhancing globular tissues suggesting residual or recurrent tumour (5); (4) high-signal intensity in the IAC before contrast medium administration, probably related to graft with fat/fascia/muscle (2). Prospective 1-to 2-year follow-up studies were available in 8, 5, and 1 patients in groups 2, 3, and 4 respectively. In group 2, dural enhancement remained unchanged in 5 patients and decreased in 3. In group 3 follow-up showed 1 tumour recurrence (surgically confirmed) and 4 stable abnormalities. In group 4, follow-up in 1 of the 2 patients was stable. In groups 1 and 2, the MRI features correlate well with complete tumor removal. Whether follow-up in these groups is indicated needs to be determined. In group 3 residual or recurrent tumor cannot be excluded. In group 4, grafts may prevent adequate visualization of the IAC.

High fractional dose irradiation of advanced head and neck cancer. Implications for combined radiotherapy and surgery.

Short-course, high fractional dose radiation therapy was compared with the conventional protracted radiation schedule in the treatment of advanced (stages III and IV) head and neck cancer. Sixty-four patients with surgically unresectable squamous cell carcinoma were randomized to receive either 6,000 to 7,000 rad in six to seven weeks or 4,000 to 4,800 rad in two to three weeks. The palliative benefits of irradiation were comparable in the two treatment arms, and complete tumor regression was observed in the majority of patients in both groups. There was no difference between the groups with regard to either short-term normal tissue radiation reaction or long-term complications. High fractional dose irradiation appears to yield results equivalent to those of conventionally fractionated radiation therapy in advanced head and neck cancer and deserves further study both as primary treatment and in combination with surgery.

Temporal bone disease: a comparison between high resolution computed tomography and pluridirectional tomography.

Sixty-five patients with suspected ear disease were examined with CT, and abnormalities were detected in 42 of them; 58 of these patients also had pluridirectional tomographic examinations. Eighteen of the patients in whom abnormalities were detected underwent exploratory surgery. CT was useful in the diagnosis of tympanic membrane swelling, fluid in the middle ear, cholesteatoma, granulation tissue, and adhesions. The superior contrast resolution of CT allowed for the visualization of ossicles when they were surrounded by an inflammatory mass or by blood. In trauma cases, axial images facilitated visualization of longitudinal fractures, which frequently pass through the geniculate ganglion of the facial nerve. CT and pluridirectional tomography were comparable in the demonstration of disease that involved the mastoid air cells, although fluid in air cells was more easily demonstrated by CT. Pluridirectional tomography was superior to CT in the demonstration of bone destruction; CT, however, was more sensitive in the diagnosis of lateral semicircular canal fistula. Based on this analysis, we recommend that these two modalities be used in a complementary fashion to evaluate suspected middle ear disease.
