Non-occupational recurrent bilateral pneumoparotitis in an adolescent
Authors: Ferlito Alfio , Andretta Marilisa , Baldan Marco , Candiani Francesco 
Published: November 2007

AbstractThis is a case report of recurrent bilateral parotid swelling with intraglandular gaseous bubbles in a 14-year-old boy, together with a review of the literature on this condition, which is usually called pneumoparotitis. The disorder has been reported as an occupational hazard in wind instrument players and glass-blowers and also as a rare non-occupational disease, mainly in adolescents and often associated with psychological problems.
Cystic lymphangioma in the adult parotid
Authors: Livesey J. R. , Soames J. V. 
Published: November 2007

AbstractCystic lymphangioma is a congenital lesion which rarely presents in adult life and even less commonly arises within salivary tissue. We report the sudden appearance of a large cystic lymphangioma within the parotid gland of a young man and discuss the management of this rare condition.
The Welch Allyn Audioscope and Microtymp: their accuracy and that of pneumatic otoscopy, tympanometry and pure tone audiometry as predictors of otitis media with effusion
Authors: Vaughan-Jones R. , Mills R. P. 
Published: November 2007

AbstractResults of standard audiometry and tympanometry were compared with the Welch Allyn ‘Audioscope’ and ‘Microtymp’, in the diagnosis of secretory otitis media, in 100 children.Standard pure tone audiometry had a specificity of 92 per cent and sensitivity of 51.6 per cent. The Welch Allyn ‘Audioscope’ a specificity of 84.2 per cent and sensitivity of 57.5 per cent; standard tympanometry a specificity of 71 per cent and sensitivity of 88 per cent; the Welch Allyn ‘Microtymp’ a specificity of 63 per cent and sensitivity of 90 per cent.In view of cost, portability, and speed of testing the Welch Allyn instruments would be particularly suitable for community screening.Pure tone audiometry with a pass threshold of 25 dB, at 2 and 4 kHz is a poor indicator of effusion.

Authors: Derias N. W. , Chong W. H. , O'Connor A. F. Fitzgerald 
Published: November 2007

AbstractA 12-year-old boy presented with a three-month history of a painful parotid swelling. Fine needle aspiration cytology indicated a pleomorphic adenoma—an uncommon lesion in a child. This diagnostic technique plays a useful role in the investigation of head and neck swellings.
An unusual prevalence of complications of chronic suppurative otitis media in young adults
Authors: Shamboul K. M. 
Published: November 2007

AbstractThe complications of chronic suppurative otitis media as seen in 117 patients are presented. Fifty per cent of the patients had cholesteatoma, and 28 per cent revealed complications. Two-thirds of these complications, especially the serious intracranial ones, were encountered in young females. This female predominance was attributed to late presentation because of social reasons, or to undue susceptibility to the destructive effect of cholesteatoma.Radical and modified radical operations were recommended to render the ears safe, as most of the patients came from distant rural areas and were judged to have poor compliance to report for regular checks.
Computer simulation of human tympanic membrane
Authors: Bhide Avinash 
Published: November 2007

AbstractBecause of the difficulties in studying the mechanical properties of the human tympanic membrane in situ, structural data from the cadaveric tympanic membrane samples is used for simulation of the surface structure of the tympanic membrane with the help of a computer. The hitherto poorly understood contour of the tympanic membrane is available for the development of a tympanic membrane and middle ear model.
The use of pyriform sinus mucosa for reconstruction after vertical partial laryngectomy
Authors: Salam M. A. , El-Kahky M. , El-Mehiry H. 
Published: November 2007

AbstractThis prospective study included 30 patients with glottic carcinoma of the larynx who were treated primarily by vertical partial laryngectomy. The pyriform sinus mucosa was used to reconstruct the new laryngeal wall and to form a pseudo-vocal fold at the side of resection. Our results showed that 90 per cent of patients were decannulated, 80 per cent were able to eat a normal diet, 70 per cent developed excellent voice quality after surgery and a 97 per cent three-year survival was achieved. The pyriform sinus mucosa proved to be a reliable material for reconstruction after vertical partial laryngectomy.
New methods of dealing with the complications of panendoscopy
Authors: Mendel Paul , Anaes F. C. , Bristow Aubrey 
Published: November 2007

AbstractA 70-year-old man with chronic obstructive airways disease was scheduled to undergo panendoscopy following a course of radiotherapy for carcinoma of the larynx. He was anaesthetized using a propofol infusion and high frequency jet ventilation (HFJV). The jet ventilation catheter was left in situ at the end of the procedure. This enabled oxygenation to be maintained in the presence of post-operative laryngospasm by re-attaching the jet ventilator. Subsequently he developed respiratory failure, and a Bullard laryngoscope was used to visualize the vocal folds despite oedema of the tumour which made direct laryngoscopy impossible.A catheter was passed through the biopsy channel of the Bullard, enabling HFJV to be commenced. A conventional endotracheal tube was then railroaded over the catheter to facilitate conventional ventilation.
Ionomeric bone cement in neuro-otological surgery
Authors: Ramsden Richard T. , Herdman Rory C. D. , Lye Richard H. 
Published: November 2007

AbstractThe use of a polymaleinate glass ionomer cement in 80 neuro-otology cases is described. It has pf oved of great value in translabyrinthine acoustic neuroma surgery, reducing the incidence of CSF fistula to nil. It is the method of choice for fixation of the Nucleus cochlear implant, and has many other applications in the field of otology and neuro-otology. It is easy to use and appears to have no side effects.
Cochlear implants for congenital deformities
Authors: Phelps P. D. 
Published: November 2007

AbstractThere have been few accounts of multi-channel cochlear implants in patients with congenital structural deformities of the inner ear which are associated with severe and sometimes progressive deafness. These malformations can now be recognized easily on 2 plane thin section high resolution CT studies which are mandatory for the pre-implantation assessment. However, no attempt seems to have been made to describe which of these malformations would be suitable for an implant or for which would this procedure be contra-indicated. True Mondini deformity of both the cochlea and dilated vestibular aqueduct type would appear suitable for a multi channel implant, but this type of implant should not be used for a primitive otocyst, severe labyrinthine dysplasia or the characteristic X-linked deformity.
Draffin and his rods
Authors: Courtnay Bennett J. D. , Young J. Riddington 
Published: November 2007

AbstractDraffin's rods or bipods are now a well-known, internationally accepted ENT instrument. Before their invention in 1951, the attendant anaesthetist or nurse was obliged to support the mouthgag during tonsillectomy.Research into the life of their originator, David Alexander Draffin, reveals that in addition to his evident design skills, he was a surgeon of courage, wit and great charm.

Familial stapes superstructure fixation
Authors: Kinsella J. B. , Kerr A. G. 
Published: November 2007

AbstractCongenital stapes superstructure fixation was found in a mother in both ears and her daughter in one ear. The head of the stapes was fixed to the pyramid by a bony bar which lay immediately superior to a normal stapedius muscle. Removal of the bony bar resulted in normal hearing, which has been maintained. We believe that these are the first reported cases of this abnormality.
Idiopathic spontaneous tonsillar haemorrhage
Authors: Vaughan M. M. , Parker A. J. 
Published: November 2007

AbstractSince the advent of antibiotics major spontaneous tonsillar haemorrhage is extremely rare. The causes are usually ascribed to vessel wall erosion secondary to bacterial infection or infectious mononucleosis. We report the case of a 20-year-old female, presenting to the ENT department with tonsillar bleeding in the absence of any identifiable infective or traumatic process.
The use of balloon catheters in the treatement of epistaxis
Authors: McFerran D. J. , Edmonds S. E. 
Published: November 2007

Inflatable balloon catheters are widely used in the treatment of severe epistaxis and are designed to be filled either with air or liquid. A postal survery revealed that 87 per cent of respondents used an inflantant which was deemed inappropriate by the manufacaturer. When ballons designed for water or saline were filled with air, they defalted rapidly, in some cases beings virtually empty after 24 hours. Better and more accessible instruction leaflets are required if the balloons are to be used as intended.Foley catheters are frwquently used as nasopharyngeal packs, in conjunction with anterior nasal packs. Paraffin in the commonly used anterior packs damages the rubber of the catheter, resulting in the balolon bursting. This should be recognized by clinicans as a possible cause of rebleeding.
A randomized study of the surgical management of children with persistent otitis media with effusion associated with a hearing impairment
Authors: Dempster J. H. , Browning G. G. , Gatehouse S. G. 
Published: November 2007

The object of this study was to compare the effect on the hearing of the insertion of a grommet, with or without adenoidectomy, against a non–surgically managed control ear in children with persistent hearing impairment due to otitis media with effusion.Seventy–eight children (44 boys, 34 girls, mean age 5.8 years) with documented bilateral otitis media with effusion associated with a bilateral hearing impairment (pure tone average air conduction thresholds over 0.5, 1 and 2 kHz of ≥25 dB HL) over a three month period were admitted to a randomized, controlled trial. Each child was randomized to have or not to have an adenoidectomy. The ears in each child were then randomly allocated to have a grommet (tympanostomy tube) inserted. The children's hearing status was reviewed six and 12 months post–operatively. During follow–up, should a child redevelop a persistent bilateral hearing impairment (as defined above) for three months they were managed with a hearing aid. Thus no child had repeat insertion of a grommet.Surgery of each type had an effect on the hearing and the presence of otitis media with effusion at six months post–operatively but not at 12 months when it was no different from natural resolution.If resolution of the otitis media with effusion is the outcome measure, then adenoidectomy alone is significantly better than no surgery but only in boys rather than in girls. Even in boys it only resolves about 60 per cent of effusions. However, when combined with a grommet (one insertion) adenoidectomy gives no greater resolution (89 per cent compared with 86 per cent).If improvement in hearing is the outcome measure, the overall results are similar. Adenoidectomy alone has an effect but if a grommet is inserted, adenoidectomy in addition does not improve the overall effect. However, these findings are not the case when analysed regarding the sex of the subject mainly because of the higher natural resolution rate in girls. In them, at six months surgery of any type or combination has no effect whereas in boys there is an additive effect of adenoidectomy on grommet insertion. Hopefully further studies can be conducted in larger numbers to investigate the differing effect in boys and girls suggested in this study.

Published: November 2007

AbstarctWe investigated the DNA ploidy patten in thirteen primary and four recurrent rhabdomyosarcomas of teh head and neck from thirteen adult patients and conrrelated the findings with other clinicopathological factors and clinical outcome. Twelve (92.7 per cent) of the primary neoplasms manifested an aneuploid DNA pattern. All recurrent lesions were DNA aneuploid with DNA indices (DIs) Corresponding to their primary neoplasms. No correlation beteween the ploidy pattern and histological subtypes, tumours location, clinical stage and patient's clinical course was found. In this study, only two patients were long-term, survivors. Both patients had stage I neoplasms that were located in non-parameninigeal sites which manifested an alvellar histological pattern. Our data indicate that adult rhabdoyosarcomas of adult and neck are preponderantly DNA aneuploid and are highly aggressive malignant neoplasms. Our results alson suggest that tumours which are low stage and in a non-parameningeal location may pursue a less aggressive course.
Severe cochlear dysplasia causing recurrent meningitis: a surgical lesson
Authors: Stevenson D. S. , Proops D. W. , Phelps P. D. 
Published: November 2007

AbstarctMeningitis may be the sole presenting sign of a cerebrospinal fluid (CSF) fistula of the temporal bone. An eight-year-old boy suffering from recurrent meningits was found to hav ebilateral severe cochlear dysplasia. Bilateral tympanotomies were performed, planning to obliterate each vestibule. In the right ear a stapedectomy was oerfirned, resulting in terrntial ‘CSF gusher’ and difficulty in packing the vestibule. CSF rhinorrhoea requiring revision surgery and twon episodes of gram-negative bacterial meningtis complicated the post-operative management, resulting in a prolonged hospital stay. Subsequently, the left ear was managed in a different fasion, leaving the stapes in situ, with grafts placed to seal the oval window nche. We would recommended this alternative procedure in cases of severe cochlear dysplasia, where abnormalities of the vestibule and basal turn of the cochela mean that performing a stapeddectomy to pack the vestibule may result in a severe ‘CSF gusher’, by opening directly into the subarachnoid space.
Salivary neoplasms of the palate: a flow cytometric and clinicopathological analysis
Authors: Carrillo Rosario , Batsakis John G. , Weber Randal , Luna Mario A. , El-Naggar Adel K. 
Published: November 2007

AbstractIn order to test the clinical and prognostic significance of flow cytometrically assessed DNA content in minor salivary gland tumours we evaluated 75 neoplasms of the palate, 55 of which were carcinomas. Benign neoplasms were exclusively DNA diploid with low S-phase fractions while 22 per cent of malignant tumours manifested a DNA aneuploidy and 23.5 per cent high S-phase fractions (>5 per cent). Significant statistical correlations between DNA content and tumour size, histological grade, lymph node metastasis and lethality were observed. Our findings suggest a potentially important role for flow-cytometry in the evaluation of these neoplasms.
What causes acute otitis externa?
Authors: Russell J. D. , Donnelly M. , Mcshane D.P. , Alun-Jones T. , Walsh M. 
Published: November 2007

AbstractExternal otitis is an extremely common condition and can affect between five to twenty per cent of the patients attending ENT clinics (Hawke et al., 1984).Its precise pathogenesis remains unclear, despite several aetiological classifications in the literature. The aim of this study was to investigate the relationship between infection, water exposure and trauma and the development of acute otitis externa. The study comprised 100 patients with their first attack of otitis externa and 150 age and sex matched controls. In only 40 per cent of cases could a primary microbiological cause be found.There was no significant statistical difference found between the two groups regarding the use of agents capable of traumatizing the external canal. Regular swimming, showering and hair washing were significantly more common in patients with acute otitis externa. Allergic disorders were nearly three times more common in the external otitis group suggesting a possible immunological aetiology.

When is a decibel not a decibel?: The application of decibel scales and calibration in clinical audiology
Authors: Beynon Graham 
Published: November 2007

AbstractDecibel scales are a very important but potentially confusing subject for the clinician. Misunderstanding can, at worst, lead to inappropriate management which is detrimental to the patient. This paper sets out, from the viewpoint of an acoustician, the calibration and meaning of the various decibel scales in common use, shows how they are applied to the clinical setting, and explains their limitations.
Prevalence and aetiology of profound deafness in the general population of Sichuan, China
Authors: Liu Xuezhong , Xu Lirong , Zhang Silig , Xu Yin 
Published: November 2007

AbstractPeople with profound deafness were surveyed in the general population of Sichuan. The results showed that the overall prevalence in Sichuan was 0.186 per cent (236/126 876) of the general population, males 0.2 12 per cent (135/63 741), females 0.159 per cent (101/63 135) (p 0.05). Two hundred and fifteen (92 per cent) cases were older than 10 years, but 227 (96 per cent) lost their hearing under the age of 10 years, 192 (80 per cent) under five years, and 104 (44 per entwere congenital). There was no significant difference in prevalence of deafness between the population located in urban and rural areas. However, the population living in the flat area and mountain area had a much higher prevalence than that of the hill people (p 0.05). Amongst the nationalities investigated, there existed significant differences in prevalence. Both the population of the Hui and the Lisu presented a significantly higher prevalence of profound deafness than that of the others. In aetiology, genetic factors may account for 43 per cent (101/236) of the cases, amongst which, autosomal recessive (AR) deafness is 92 per cent (95/104) and autosomal dominant (AD) 5.4 per cent. Environmental factors were thought to be responsible for 35.6 per cent (84/236) of cases, including infectious diseases (31 per cent), ototoxic antibiotics (2.6 per cent), injury (1.7 per cent), and asphyxia (0.4 per cent). The number of cases of unknown origin were 20.3 per cent. It is suggested that, in China, the importance of genetic factors in hearing impairment should be emphasized. In addition, infectious diseases and ototoxicity play an important role in causing deafness.

MRI features in a malignant glomus jugulare tumour
Authors: Athanassopoulou Alexandra C. , Vlahos Labros L. , Gouliamos Athanassios D. , Kailidou Eliana D. , Papailiou John G. , Angeli Smaragde S. 
Published: November 2007

AbstractMagnetic resonance imaging (MRI) features in a case of malignant glomus jugulare tumour are reported. Chemodectomas are benign in 95 per cent of cases and malignant in five per cent. Only one case report of CT findings in this unusual CP angle tumour with pulmonary metastases has been cited in the literature.It is concluded that MRI can provide useful information about the nature of chemodectomas although it cannot dislinguish between benign and malignant tumours, except when regional lymph nodes are involved or when distant metastases exist.

The nasopharynx, eustachian tube and otitis media
Authors: Sadé Jacob 
Published: November 2007

AbstractIt has been classically hypothesized that a mass in the nasopharynx causes an obstacle to air flow through the eustachian tube, thereby creating a negative pressure in the middle ear followed by an effusion. However, examination of the relevant data concerning the supposed obstruction of the eustachian tube by nasopharyngeal carcinomas, choanal polyps and adenoids does not seem to support this cause and effect relationship. Evidence points to other more sophisticated mechanisms which cause negative pressure and an effusion in pathological middle ear conditions. While the hypothesis of a nasopharyngeal mass as the usual obstructive cause of middle ear effusion is hard to maintain, evidence does exist to support the origin of middle ear infection, as seen in acute and secretory otitis media, as being associated, at times, with an ascending infection from the nasopharynx.
