Mandibular osteotomy complicated by styloid pain.

Although temporomandibular joint pain is not a rare complication of mandibular surgery, styloid pain syndrome has not been recognized heretofore as a complication of mandibular osteotomy. Usually styloid pain syndrome occurs following tonsillectomy or de novo. Most styloid syndromes involve the styloid process, the stylohyoid attachments, or the carotid artery. This article presents a case of stylohyoid pain syndrome caused by stretching of the stylomandibular ligament following mandibular osteotomy. Additional surgical intervention was required to relieve the symptoms in this case. Styloid process pain syndromes are reviewed.

Phantom limb phenomenon in patients with leprosy.

The phantom limb phenomenon (PLP) was studied in 42 patients with leprosy who had limb amputation and/or digital shortening; some of the patients also had another type of limb deformity, such as claw-hand or foot-drop, which did not involve significant loss of tissue. Thirty-eight (90 per cent) of the patients reported having at least one phantom limb (PL) for a missing or deformed part. Associated with each of the three types of limb defects, two descriptively and experientially distinct types of PLs were found: the paresthetic or typical (TPL) and the painless or natural (NPL). Descriptions of the TPL and the NPL are given. The findings were compared to various reports, particularly those of Stetter and Frederiks. The leprosy TPL was similar both to the PL of amputees as frequently described in the literature, and to what Stetter and Frederiks termed the PL sensations. A close correspondence, if not identity, was noted between the NPL of leprosy patients and the equivalent categories of Stetter's PL experience and Frederiks' PL as such. Included in these three designations are aspects of the PLP that are associated with the normal, intact limb; these aspects are thought to be usual concomitants of the PLP and to constitute manifestations of the persistence of the normal body image. From our findings, we conclude that for the appearance of a PLP, the actual loss of a part of a limb, whether slow or sudden, is not required, but the loss of its sensorimotor functions is sufficient.

Evaluation of nondistended pyriform sinus without respiratory maneuvers.

Detection of a nondistended pyriform sinus on cross-sectional imaging studies represents a diagnostic dilemma. The finding may be an inconstant physiologic phenomenon without clinical significance, or it may be due to tissue thickening and lack of pliability related to neoplasia or inflammation. Rescanning during respiratory maneuvers may clarify the anatomy, but full patient cooperation is needed. We demonstrate a method (turning the patient's head away from the side of the nondistended sinus) that induces distention of the pyriform sinus but does not require active patient participation.

MR angiography of peripheral posterior inferior cerebellar artery aneurysms.

OBJECTIVE: A small subset of posterior inferior cerebellar artery (PICA) aneurysms arise distal to the vertebral artery origin of the PICA. We present two such cases seen on conventional angiography and MR angiography (MRA). MATERIALS AND METHODS: The findings in two patients are presented. In one the aneurysm presented with subarachnoid hemorrhage. The second was found incidentally but later ruptured. RESULTS: There was good agreement between the appearance of the aneurysms on MRA and conventional angiography. CONCLUSION: Awareness of the possibility of peripheral PICA aneurysms and their features is important. The positioning of the volume of excitation for MRA may have to be adjusted to include a very low PICA caudal loop.

The sacrum: pathologic spectrum, multimodality imaging, and subspecialty approach.

The sacrum is a structure that is imaged by both general and subspecialty radiologists. A wide variety of disease processes can involve the sacrum either focally or as part of a systemic process. Plain radiographs, although limited in evaluation of the sacrum, should be carefully examined when abnormalities of the sacrum are suspected. Cross-sectional imaging, particularly computed tomography and magnetic resonance (MR) imaging, plays a crucial role in identification, localization, and characterization of sacral lesions. Congenital lesions of the sacrum, including sacral agenesis and meningocele, are optimally imaged with MR. The most common sacral neoplasm is metastatic disease. Primary neoplasms of the sacrum, which include giant cell tumor, chordoma, and teratoma, are infrequent. Infection of the sacrum or sacroiliac joint is most often due to contiguous spread from a suppurative focus. A wide variety of arthritic disorders such as ankylosing spondylitis and osteoarthritis can involve the sacroiliac joints as part of a localized or systemic process. Sacral fractures related to acute trauma or repetitive stress are difficult to diagnose and treat. Knowledge of these abnormalities and familiarity with the imaging of these processes will allow radiologists of all subspecialties to contribute to the diagnosis and management of sacral disorders.

Handling and acceptability of the Easi-Breathe device compared with a conventional metered dose inhaler by patients and practice nurses.

This study compared the handling and acceptability of the Easi-Breathe, a breath-actuated metered dose inhaler (MDI), with that of a conventional MDI. A total of 104 patients and 14 practice nurses took part in interviews at a central location. An additional 100 practice nurses were interviewed in a telephone study. Significantly more patients (86%) found Easi-Breathe easier than a conventional MDI to use correctly (p < or = 0.001). Overall, more patients preferred Easi-Breathe (82% vs 18%; p < or = 0.001), ease of use and confidence in successful dose delivery being the main reasons for their preference. Nurses thought that Easi-Breathe was easier for the vast majority of patients (97%) to use correctly, as well as being easier to teach and to use correctly in a crisis (p < or = 0.001). Overall, 79% of nurses preferred the Easi-Breathe to the conventional MDI (p < or = 0.001), ease of use and ease of teaching being the main reasons for their preference.
