Objectives: To investigate reasons for prolonged hospitalisation of children with tracheostomies once they are medically fit for discharge. Methods: Retrospective, cross-sectional study of 101 children undergoing tracheostomy between 2000 and 2010. Results: Of the study patients, 44.6 per cent did not spend any time in hospital once medically...
Article
Objectives: Hairy polyps are rare, congenital malformations of the oropharynx and nasopharynx. To date, approximately 145 cases have been reported. However, the histogenesis of these lesions remains unclear. Case report: We report the case of a 2-day-old neonate presenting with a hairy polyp attached to the left palate, who re-presented aged 16...
Article
Congenital laryngeal cysts are a rare cause of neonatal airway obstruction. Two varieties can be distinguished, ductal cysts and saccular cysts. Treatment remains controversial, particularly with regard to saccular cysts, with some believing that endoscopic procedures leave cysts more prone to recurrence. We reviewed our management of congenital la...
Article
The human papilloma virus (HPV) can cause laryngeal papillomatosis in childhood. The aetiology is thought to be vertical transmission. Clinically these children are usually asymptomatic for the first 6 months of life. As the papillomas develop locally, symptoms begin to develop. The symptoms range from voice change to frank hoarseness, and 'noisy'...
Article
To assess whether the use of ice-lollies after tonsillectomy with or without adenoidectomy in children aged 2-12 reduces pain in the immediate postoperative period. A prospective, randomised, single-blinded study design consisting of two groups with an intention to treat analysis. Tertiary referral centre. Children aged 2-12 undergoing tonsillectom...
Article
Hairy polyps are uncommon developmental malformations of the oropharynx. They are frequently pedunculated and can cause respiratory distress in the neonate. Hairy polyps are usually diagnosed with MRI but can be well seen at US. To our knowledge, the sonographic features have not been previously reported.

We present a case of a 43-year-old man who attended the ENT clinic complaining of bilateral hearing loss. He had multiple bony swellings in both ear canals that mimicked exostoses. An audiogram showed bilateral symmetrical mixed hearing loss. Excision was carried out to facilitate the use of a hearing aid. Intraoperatively, the swellings were confl...
Article
A wide range of lasers have been used in the larynx. Diode laser is a portable and relatively inexpensive laser which is delivered via a glass fibre hand-held probe. The objective of this study was to report our experience with the use of diode laser in a variety of paediatric airway pathologies. In this study, 90 diode laser laryngeal procedures w...
Article
To identify regional surgical referral patterns for adenotonsillectomy in children with obstructive sleep apnoea to our tertiary centre with paediatric intensive care unit facilities and to establish guidelines for elective paediatric intensive care unit referral and admission. Two methods were used. A questionnaire was sent to ENT consultants in f...

Article
Thyroid carcinoma is rare in children and adolescents but tends to behave in a more biologically aggressive manner when compared with the disease in adults. Despite this, the prognosis has been reported to be very good in several series. Papillary carcinoma is the commonest type encountered. We report and discuss a case of a 2-year-old child with p...
Article
Subglottic cysts are associated with prematurity and periods of early neonatal intubation and are a rare cause of infant stridor. In this study we analyse our experience of this rare but important problem. We discuss the aetiology, diagnosis and management of subglottic cysts. We carried out a retrospective review of all cases of subglottic cysts p...
Article
We describe a new nasal stent for the treatment of bilateral congenital choanal atresia. The stent is made up of reinforced endotracheal tube mounted on a portex carrier tube. It potentially causes less internal crusting and stent blockage and is secured without sutures. It remains patent for at least 4 weeks. We have used the stent successfully in...
Article
Bronchogenic cysts are rare, benign, congenital lesions that occur as a result of aberrant development of the tracheobronchial tree during embryogenesis. They usually present during the first decade of life and are encountered predominantly within the mediastinum or the lung parenchyma. In a few instances, they appear within the neck mimicking a ne...
Article
Most tonsillectomies are carried out by dissection. Only a small minority of otolaryngologists still routinely perform guillotine tonsillectomy. We carried out a prospective study on 86 children undergoing tonsillectomy utilising a standard anaesthetic and analgesic regimen to compare post-operative pain after dissection tonsillectomy and guillotin...
Article
The nasal mucosal pH is approximately 5.5-6.5, and increases in rhinitis to 7.2-8.3. This knowledge has not led to the widespread measurement of the nasal mucosal pH as an objective clinical parameter. The purpose of this study was to assess whether repeatable measures of nasal mucosal pH could be obtained in the clinical setting. Fifty-four adults...
Article
Lancefield group A streptococcal upper respiratory tract infections are well known to be precursors of a number of disease processes. That they frequently herald a first attack of guttate psoriasis or a reactivation of chronic plaque psoriasis is well recognized, though this is perhaps more true among dermatologists than otolaryngologists. This pap...
Article
This study was designed to determine the acceptance and effectiveness of a hearing aid in the management of children with persistent hearing loss due to glue ear (otitis media with effusion [OME]). Forty-eight children with OME, in whom the main symptom was deafness, were treated with a hearing aid instead of surgery and reviewed at 3-monthly inter...
Article
Light microscopic autoradiography were prepared of isolated guinea pig endolymphatic sac (ES) tissue incubated with iodine (I)-125-labeled insulin (insulin 1125). These demonstrated specific binding of the insulin 1125 to receptors in the ES. Receptor-mediated endocytosis of the insulin-receptor complex is postulated to occur, and the relevance of...
Article
A prospective study on the effect of grommet insertion on the passive Eustachian tube opening pressure was undertaken in children's ears with otitis media with effusion. After an initial immediate improvement following aspiration of the middle ear no further change in Eustachian tube function occurred over 4 subsequent weeks. Grommet insertion prob...
Article
Middle ear pressure and nasal airway resistance were measured over 7 1/2h in 8 subjects (age 18-32) with symptomatic acute upper respiratory tract infection. The mean middle ear pressure was -13 +/- 1.5 daPa (s.e.m.) with a range between 65 to -140 daPa. The mean total nasal resistance was 0.4 +/- 0.02 Pa/cm3/s (s.e.m.) with a range between 0.20 to...
Article
A pigmented lesion of the soft palate was excised to exclude melanoma. The histology suggested an amalgam tattoo which was confirmed on energy dispersive X-ray analysis by the detection of silver and copper. This represents a very rare mimic of melanoma of the soft palate.
Article
Middle ear pressure was recorded from 396 ears and aural symptoms enquired of 198 adult subjects with seasonal allergic rhinitis. Evidence of Eustachian tube dysfunction was found in 24% of subjects. Increased duration of exposure to pollen over a further 2 weeks increased the incidence of Eustachian tube dysfunction to 48%. The development of Eust...
Article
We present two cases of extra cranial arteriovenous malformations, which presented as pulsatile tinnitus. They were originally diagnosed by clinical examination and both lesions were subsequently confirmed by angiography and their feeding vessels defined. One case was managed by surgical excision, which produced relief of symptoms. The diagnosis an...
Article
Spontaneous changes in middle ear pressure were measured tympanometrically in 15 healthy adults over 7.5 h under basal conditions. Despite fluctuation of middle ear pressure no temporal pattern existed and there was no evidence of reciprocal changes in pressure between sides. When awake but at rest the middle ear pressure fluctuates around ambient...
Article
The relationship between unilateral changes in nasal airway resistance and the ipsilateral middle ear pressure were investigated in 8 otologically and rhinologically normal adults over the course of 7 1/2 h under laboratory conditions. Despite mean changes in unilateral nasal resistance of 0.75 Pa/cm3/s associated with the nasal cycle, no correlati...
Article
The accuracy of a computer-based recording system of operative procedures was audited at a major district general hospital. The system is supposed to provide accurate records of theatre activity, to allow for improved nursing resource allocation and provide surgeons with a basic record of their operations. Mistakes were present in the details of 27...
Article
A lingual abscess is a great rarity. Only two cases have ever been reported from the United Kingdom, and only three cases have been recorded outside of India in the past fifty years. The third British case is reported and the previous literature reviewed, along with discussion of the aetiology, presentation, bacteriology and management of this rare...
Article
The effect of a change in posture from sitting erect to lying supine and horizontal on middle ear pressure was investigated in 5 healthy adults and 5 adults with symptoms of an acute upper respiratory tract infection (URTI). The change in posture had no significant effect on middle ear pressure in the healthy subjects (p greater than 0.05). In thos...
Article
A prospective trial was carried out to assess whether mucociliary clearance (MCC) is either adversely affected or improved in the early weeks after nasal surgery. Three different subgroups of patients were studied: those having septoplasty, nasal polypectomy, or turbinectomy. MCC was assessed by the saccharine transport method. 40% of patients with...
Article
This study presents the results of a 20 year review of maxillary sinus wash-outs performed on children. The results show a decreasing incidence of purulent sinusitis over the study period. Only 17 per cent of antral wash-outs undertaken yielded pus, indicating that surgical practice has failed to adequately take account of the changing disease inci...
Article
Middle ear adenomas are rare epithelial tumours. Reports indicate that neuroendocrine (carcinoid) tumours may also occur at this site, often in association with an adenomatous component. The clinico-pathological findings (including C.T. scan appearances) of such a 'mixed' neoplasm are presented together with a brief review of the few previously des...
