A retrospective study was carried out to determine the prevalence of abnormality in the paranasal sinuses in a British population having magnetic resonance imaging (MRI) scans for neurological signs and symptoms. The T2-weighted scans of 130 patients were studied. Abnormalities in the paranasal sinuses show as high signal on the T2-weighted scans and thus(More)
Pharyngo-cutaneous fistula following laryngectomy is a serious complication. The incidence worldwide varies from 7.6 to 50 per cent. The value of prophylactic antibiotics in preventing fistulae is well recognized but the type of antibiotics and the length of administration of the antibiotics is variable depending on the individual surgeon. Below we present(More)
OBJECTIVE The purpose of this study was to evaluate the accuracy of sonographically guided core biopsy in the evaluation of parotid masses. SUBJECTS AND METHODS Between 1998 and 2004, 135 patients consecutively presenting with a parotid mass were prospectively enrolled into this study. A single operator performed initial diagnostic sonography and then(More)
We describe the technique of ultrasound-guided 18 gauge (1.2 mm) needle biopsy in 16 patients with parotid gland lesions. This provides material suitable for histological analysis and can be performed quickly and safely under local anaesthesia. Thirteen of the patients had non-diagnostic blind fine-needle aspiration cytology (FNAC) with a 21 gauge (0.8 mm)(More)
Some 497 of 3085 patients with squamous cell carcinoma of the head and neck treated between 1963 and 1990 had a later radical neck dissection at some time after initial treatment. The histological slides were all reviewed, firstly to confirm the presence of squamous cell carcinoma within the neck, and secondly to ascertain whether the metastasis was to soft(More)
We describe the technique of ultrasound-guided core biopsy with a spring-loaded device in 54 patients who presented with palpable lesions of the parotid gland. Biopsy provided a sample suitable for histological analysis in all patients and was done quickly and safely under local anaesthesia. Initial diagnostic ultrasound confirmed the presence of focal(More)
Aneurysms of the extracranial portion of the internal carotid artery are rare, particularly in young patients. They usually develop following trauma, or secondary to infection involving the parapharyngeal space that extends to the vessel wall. This is a case of an internal carotid artery aneurysm presenting acutely following chiropractic neck manipulation(More)
Sinus-induced intracranial sepsis can represent a genuine medical and surgical emergency. We review 12 cases presenting to our hospitals over a five-year period. Nine were male and three were female with an age range of 16 to 74 years (mean 35.5 years). Four patients had their sinusitis diagnosed prior to admission and eight did not. Nine patients had(More)
A double blind controlled prospective trial investigated the analgesic effect of topical Bupivacaine in 15 adult patients undergoing bilateral tonsillectomy. Each patient had one tonsillar fossa exposed to Bupivacaine 0.5 per cent solution and the other to normal saline. When visited four to six hours post-operatively, 12 out of 15 patients (80 per cent)(More)
We describe a case of a malignant change in a calcified pleomorphic adenoma of the deep lobe of the parotid gland in a patient whose initial symptom was facial pain. We also discuss the relative merits of the different imaging modalities as they apply to the parotid gland.
