OBJECTIVE To investigate the incidence of abnormal findings on brain MRI in paediatric cochlear implantation candidates. METHODS Retrospective review of brain MRI scans of cochlear implant patients between 2000 and 2009 who underwent MRI brain as part of their pre-operative work-up. RESULTS MRI scans of 162 patients were reviewed (76 female patients and(More)
Neuroblastoma is the most common extra-cranial solid malignancy in children and the most common tumour occurring during infancy. This tumour arises from undifferentiated precursor cells of the sympathetic nervous system. The abdomen (65 per cent) is the most common site for these tumours, followed by the throat (15 per cent), pelvis (5 per cent) and(More)
OBJECTIVES Adenoidectomy and/or tonsillectomy are commonly performed in tertiary pediatric hospitals for the management of obstructive sleep apnea, often in children with significant comorbidities. This study examines the peri-operative course of a large series of complex patients undergoing such surgery at a major pediatric centre, reporting particularly(More)
OBJECTIVE To evaluate the effectiveness of lignocain 2% and oxymetazoline 0.025% compared to oxymetazoline 0.025% alone when administered prior to fibreoptic nasendoscopy in paediatric patients. STUDY DESIGN Prospective, randomized controlled, double-blind study. A group of 56 children, undergoing nasendoscopy to determine adenoidal size, were randomized(More)
OBJECTIVE To compare adenoidectomy using suction-diathermy ablation to curettage adenoidectomy with respect to operative time and adenoid regrowth at 6 months after surgery. STUDY DESIGN A prospective, randomized, single-blind, study to compare two methods of performing adenoidectomy. A group of 100 children, undergoing adenoidectomy alone or in(More)
OBJECTIVES Intracapsular tonsillectomy (tonsillotomy) has been used internationally, mainly in the management of obstructive sleep apnoea, rather than recurrent tonsillitis, with few published data evaluating its use for this latter indication. We present long-term prospective data from 500 paediatric cases undergoing Coblation® intracapsular tonsillectomy,(More)

He had been unable to remove them, and both magnetic parts of the ear studs were still present in his nose. Examination of the nose was difficult, as he was unco-operative and his nose was filled with mucus and crusts.(More)

The borders of the anterior triangles are the inferior border of the mandible, the sternocleidomastoid muscle and the midline. The borders of the posterior triangle are the sternocleidomastoid muscle, the trapezius muscle and the clavicle. The major structures that can be(More)
