    ABSTRACT: Treatment of frontal sinus fractures has been controversial for years. The aim of treatment, besides cosmetic restoration, is to create a “safe” sinus especially in those with evidence of injury to the frontal sinus outflow tract. Early and late complications include acute and chronic sinusitis, mucocoele and mucopyocoele formation, brain abscess and osteomyelitis. Osteoplastic flap with frontal sinus obliteration or cranialisation is most commonly performed. With the advent of modern endoscopic and advanced imaging techniques, endoscopic sinus surgery for treatment of diseases of the frontal sinus is ever increasing. In this paper, we describe our successful experience using a single-stage, combined open and transnasal endoscopic technique in management of patients with anterior table frontal sinus fractures involving the frontal sinus outflow tract.

    ABSTRACT: To assess the correlation between clinical symptoms and examination findings with severity of obstructive sleep apnea (OSA). Prospective observational study. Otorhinolaryngology sleep clinic in a tertiary referral centre. Consecutive patients referred to the sleep clinic with a suspected diagnosis of OSA. Body mass index (BMI), Epworth Sleepiness Scale (ESS) score, tonsil size, modified Mallampati index (MMP), Müller manoeuvre, reflux finding score (RFS), apnea-hypopnea index (AHI), lowest oxygen saturation, and percentage of rapid eye movement sleep. Eighty patients (14 female, 66 male), with a mean age of 42.9 years (range 22-66), were included in the study. The mean BMI was 27.6 (range 20-39). A correlation was found between ESS score and anteroposterior pharyngeal wall collapse at the level of the soft palate during Müller manoeuvre (r=.3, p=.02). BMI was significantly associated with a history of hypertension (r=.3, p=.01), MMP (r=.3, p=.001), and lateral wall collapse at the level of the soft palate during Müller manoeuvre (r=.4, p=.0001). OSA severity correlated significantly with male gender (p=.02), history of hypertension (r=.5, p<.0001), BMI (r=.2, p=.03), MMP (r=.3, p=.003), and upper airway collapse during Müller manoeuvre. Clinical findings in patients with OSA do correlate with the severity of OSA and polysomnographic findings. The degree of upper airway collapse during Müller manoeuvre does correlate with AHI severity. Accuracy in predicting the presence and severity of OSA allows for greater cost-effectiveness in screening patients prior to polysomnography.

    ABSTRACT: Mucosal haemangiomas are unusual and typically involve frequently traumatised areas such as the lip, buccal mucosa and lateral borders of the tongue. Uvular haemangioma is rare and to our knowledge, has never been reported to cause obstructive sleep apnoea (OSA). We report an unusual case of uvular haemangioma causing loud habitual snoring and symptoms suggestive of OSA. This case report illustrates a rare cause of OSA and demonstrates the efficacy of surgery for obvious obstructive lesions of the pharynx.

    ABSTRACT: The Epstein-Barr virus-associated smooth muscle tumour (EBV-SMT) is a rare entity that has only recently been recognised. Since its first description in 1993, it has been reported only in immunocompromised patients, and generally presents as one or more non-specific mass lesions which may arise almost anywhere within the body. Because of its sporadic occurrence, non-specific presenting features and frequently unusual sites of occurrence, it often presents a diagnostic challenge for the clinician. We describe an interesting patient with an EBV-SMT which masqueraded as nasopharyngeal carcinoma, presenting with serous otitis media, nasopharyngeal mass and raised Epstein-Barr virus (EBV) serology.

    ABSTRACT: To examine the effects of oral diazepam on blood pressure and anxiety in patients with acute epistaxis. A prospective comparative study in an otorhinolaryngology tertiary referral centre. Patients with acute epistaxis requiring hospital admission. Oral diazepam. Anxiety and blood pressure levels. 32 patients received diazepam and 45 did not (control). On average, patients were hypertensive on admission (mean [standard deviation (SD)] systolic blood pressure diazepam group=157 mmHg [26], control=152 mmHg [23]; diastolic blood pressure diazepam group=87 mmHg [16], control=87 mmHg [18]). Both groups showed significant blood pressure reduction on discharge (p<0.0001) but the difference in mean blood pressure reduction between the two groups was insignificant (systolic blood pressure p=0.16, 95% confidence interval [CI]=-5 to +19 mmHg; diastolic blood pressure p=0.43, 95% CI=-8 to +10 mmHg). Anxiety was significantly lower on discharge (p<0.0001) but the difference in mean fall in anxiety scores between the two groups was insignificant (p=0.08, 95% CI=0 to +2). There was no significant correlation between total diazepam and changes in blood pressure (systolic blood pressure p=0.32; diastolic blood pressure p=0.65) or anxiety (p=0.73), nor between blood pressure and anxiety on admission (systolic blood pressure p=0.45; diastolic blood pressure p=0.72). Elevated blood pressure and anxiety in acute epistaxis patients reduced on epistaxis resolution irrespective of oral diazepam use. The elevated blood pressure does not appear to be directly related to anxiety.
