Objective: To assess the effectiveness of the nasal airflow inducing manoeuvre or 'polite yawn' technique in improving olfaction and quality of life in laryngectomised patients. Methods: Using a prospective study design, 42 patients scheduled to undergo laryngectomy at a tertiary care centre were subjected to olfaction testing before surgery and two weeks following the surgery. The nasal airflow inducing manoeuvre was taught, and the olfaction test was repeated with the patient performing the nasal airflow inducing manoeuvre. Quality of life was assessed using the Appetite, Hunger and Sensory Perception questionnaire with calculation of scores after the patient had learnt the nasal airflow inducing manoeuvre. Results: There was a significant reduction in the composite olfaction score, from a mean (standard deviation) baseline value of 4.01 (1.39) to 0.44 (0.51), two weeks after surgery (p < 0.001). After practising the nasal airflow inducing manoeuvre, the olfaction scores increased to 3.05 (1.32) (p < 0.001). Appetite, Hunger and Sensory Perception questionnaire scores ranged from 52 to 110 (normal range, 29–145), suggesting an improvement in the quality of life of patients. Conclusion: The nasal airflow inducing manoeuvre, an inexpensive, simple, patient-friendly manoeuvre, can be used in the olfaction rehabilitation of patients undergoing laryngectomy.

Objective: To determine risk factors affecting mortality in acute invasive fungal sinusitis. Method: This observational cohort study was conducted over a five-year period. Results: Of 109 recruited patients, 90 (82.6 per cent) had diabetes mellitus. Predominant fungi were zygomycetes (72.6 per cent) with Rhizopus arrhizus being most common. Of the patients, 12.8 per cent showed a positive biopsy report from radiologically normal sinuses. Factors affecting mortality on multivariate analysis were: female sex (p = 0.022), less than two weeks between symptoms and first intervention (p = 0.01), and intracranial involvement (p = 0.034). Other factors significant on univariate analysis were: peri-orbital swelling (p = 0.016), restricted ocular movements (p = 0.053), intracranial symptoms (p = 0.008), posterior disease (p = 0.058), imaging showing ocular involvement (p = 0.041), fungus being zygomycetes (p = 0.050) and post-operative cavity infection (p = 0.032). Bilateral, palatal and retromaxillary involvement were not associated with poor prognosis. Conclusion: Diagnosis of acute invasive fungal sinusitis requires a high index of clinical suspicion. Recognition of factors associated with poor prognosis can help when counselling patients, and can help initiate urgent intervention by debridement and antifungal therapy. Post-operative nasal and sinus cavity care is important to reduce mortality. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study is to document the prevalence of MR findings suggestive of idiopathic intracranial hypertension (IIH) in patients undergoing endoscopic repair of spontaneous CSF rhinorrhea (SCSFR). Methods: In a retrospective study, MR images of 117 consecutive patients who had undergone endoscopic repair of SCSFR were evaluated for features suggestive of IIH (empty sella, widened optic nerve sheath, tortuous optic nerve, flattened posterior globe, and enlarged Meckel's cave). Pituitary height was used to diagnose partial and complete empty sella. MR images were independently evaluated by two of the authors without knowledge of the clinical findings. Consensus method was used to resolve differences between the two evaluators. Results: Empty or partially empty sella was diagnosed in the MR of 105 (89.7%) patients. In 38/105 (36.2%) patients with empty/partial empty sella, no additional MR findings were present. In 43/105 (41%) patients, one or more of the MR features with high specificity for diagnosis of IIH (flattened posterior globe and enlarged Meckel's cave) were seen. In the other 24 (22.9%) additional MR findings, less specific for IIH (widened optic nerve sheath, tortuous optic nerve) were noted. Papilledema was seen in 11 of 60 (18.3%) patients who underwent funduscopic examination. All patients with papilledema had empty/partial empty sella, and 9/11 (81.8%) had an additional MR finding suggestive of IIH. Conclusion: The majority of patients with SCSFR have MR imaging features of IIH. These imaging features should be a major component of previously published modified diagnostic criteria for IIH in patients with SCSFR. [ABSTRACT FROM AUTHOR]

Objective:To investigate differences in orbital involvement in patients with invasive versus non-invasive fungal sinusitis.Method:One hundred consecutive cases of fungal sinusitis were assessed clinically and by computed tomography scan to evaluate orbital involvement.Results:Clinical orbital involvement was more common in invasive (73.5 per cent) than non-invasive (12.1 per cent) fungal sinusitis (p = 0.000). Computed tomography scanning showed similar orbital involvement in both groups, except for erosion of the floor of the orbit, which was more common in patients with invasive fungal sinusitis (p = 0.01). Extra-ocular muscle enlargement (44.4 vs 4 per cent, p = 0.01) and optic atrophy (44.4 vs 0 per cent, p = 0.003) were more common in chronic than acute invasive fungal sinusitis. Four patients (16 per cent) with acute invasive fungal sinusitis had no evidence of orbital involvement on scanning, despite clinical evidence of optic atrophy.Conclusion:Orbital involvement is more common in invasive than non-invasive fungal sinusitis. The difference is more evident clinically than on computed tomography scanning. Patients with acute invasive fungal sinusitis may have limited evidence of orbital involvement on scanning, despite extensive clinical disease. [ABSTRACT FROM PUBLISHER]
