Based on our findings, the authors recommend against placing hypopharyngeal packs for the purpose of preventing postoperative nausea and vomiting.

Cadaveric temporal bone dissection in a temporal bone laboratory is a vital component in training safe, competent otorhinolaryngologists. Recent controversies pertaining to organ retention have resulted in a more limited supply of temporal bones. Consequently, current trainees are dissecting far fewer bones than their consultants. We discuss the establishment of a temporal bone laboratory in the Department of Anatomy in the University College Cork, from the timely preparation and preservation of the tissue to its disposal. Comparisons are drawn between our experience and that of the United States training schemes. The temporal bone laboratory in Cork is the only one in existence in Ireland. The exposure and experience obtained by registrars rotating through Cork, has resulted in noticeable improvements in their operative abilities. The temporal bone laboratory remains a core component to training. It is hoped that this article may facilitate other units overcoming obstacles to establish a temporal bone laboratory.

The effectiveness of topical peppermint oil added to barium sulphate suspension in relieving colonic muscle spasm during double contrast barium enema examination was assessed in a double blind study. 141 patients were randomized either to a control group (71 patients) examined with standard barium suspension or to the treatment group which received peppermint oil mixed with the barium preparation. No residual spasm was evident in a significant proportion of patients in the treated group (60%) compared with the control group (35%) (p < 0.001). The patients' acceptability of the procedure was good and there were no adverse effects on the overall quality of the examination. In conclusion, the addition of peppermint oil to the barium suspension seems to reduce the incidence of colonic spasm during the examination. The technique is simple, safe, cheap and it may lessen the need for intravenous administration of spasmolytic agents.

Cystic fibrosis (CF) is a common inherited disorder in Caucasians in Ireland having the highest reported incidence. CF has well-recognised clinical sequelae in several physiological systems. Its' impact on the sinonasal system is less well established. We evaluated symptoms, endoscopic and computerised tomographic (CT) findings in an Irish adult CF group with the aim of characterising the relationship between these clinical features in an Irish CF group. Adult CF patients attending a specialist clinic underwent prospective evaluation of sinonasal symptoms using a specifically designed questionnaire. They subsequently underwent nasoendoscopy and CT scanning of their paranasal sinuses. Abnormalities identified were quantified using established radiological (Lund-Mackay) and endoscopic (Lund-Kennedy) scoring systems. The relationship between symptoms of chronic rhinosinusitis (CRS), endoscopic findings and CT abnormalities were then compared. Sixty-three CF patients (n = 63) were studied. 29 patients had a CT scan. Thirty-three CF patients (52%) had no symptoms of CRS. Fifty CF patients (80% of CF group) had evidence of CRS on nasoendoscopy including thirteen patients (20%) with nasal polyposis. 98% of patients scanned have positive findings on CT scan. There was no significant difference between symptomatic and asymptomatic CF groups with respect to their Lund-Kennedy endoscopic score or their Lund-Mackay CT score. 86% demonstrated one or more hypoplastic sinus. There was no increased incidence of hypoplastic sinuses amongst Δf508 homozygotes than other mutation groups.
