Fibrous histiocytoma of the larynx
Authors: Saleem M. , McArthur P. D. , Hainau B. , Velagapudi S. B. 
Published: November 2007

AbstractWe present a case of fibrous histiocytoma of the larynx in a young female who presented eight years ago and is still alive and well with no evidence of any regional invasion or distant metastasis. This rare lesion has been described in 30 cases previously of which 26 were malignant and four benign. Our case is unusual in a sense that histologically it has not been possible to determine its exact biological behaviour and growth potential. However, clinically it behaved as a low-grade malignant tumour.
Evaluation of the dizzy patient: experience from a multidisciplinary neurotology clinic
Authors: Heaton Judith M. , Barton Jason , Ranalli Paul , Tyndel Felix , Mai Ryan , Rutka John A. 
Published: November 2007

AbstractIn 1993 a multidisciplinary neurotology clinic was established at the Toronto Hospital, University of Toronto, Where patients with symptoms of dizziness were assessed by both otolaryngologists and neurologists. The results from the first 400 patients seen in consultation are described. The disease pathologies identified in this patient population with dizziness showed some significant differences from other published series, which we believe reflects the specialized tertiary nature of referrals to this clinic. A model for the collaborative investigation of the dizzy patient is provided consistent with the current trend towards multidisciplinary approaches in medicine.
Microbiology of the middle meatus in children requiring adenotonsillectomy
Authors: Gordts Frans , Nasser Ibrahim Abu , Pierard Denis , Meyvisch Paul , Clement Peter A. R. 
Published: November 2007

AbstractMiddle meatus samples were cultured in 120 children undergoing adenotonsillectomy with, or without, insertion of ventilation tubes. Every child (except one) had positive cultures. Haemophilus influenzae (62 per cent of the children), Moraxella catarrhalis (53 per cent) and Streptococcus pneumoniae (48 per cent) were the most commonly isolated bacteria. The presence of Moraxella catarrhalis and (to a lesser extent) Streptococcus pneumoniae was higher in younger children, while Haemophilus influenzae was cultured independently of age.Culture results of these middle meatal samples, carefully taken in order to avoid any contamination, probably reflect some ongoing sinus infection in these children requiring adenotonsillectomy. The problems inherent in the interpretation of surface cultures are addressed.
Acoustic evaluation of Isshiki type III thyroplasty for treatment of mutational voice disorders
Authors: Li Guo-Dong , Mu Liancai , Yang Shilin 
Published: November 2007

AbstractThe goal of this study was to determine if there are acoustical differences between pre- and post-surgical voices and to evaluate the effectiveness of Isshiki type III thyroplasty in 11 male patients with mutational voice disorders. Acoustic measures were obtained both pre- and post-operatively. A comparison of pre-and post-operative fundamental frequency (Fo), voice frequencies, and vocal intensity obtained from a sustained vowel /i/ during different phonatory tasks was made. The results from the present study demonstrated that after operation the voice frequencies were significantly decreased (p<0.05). The vocal intensity tended to reduce slightly as the voice frequency lowered. However, there were no statistically significant differences in the pre- and post-operative measures of vocal intensity (p>0.5). The preoperative high pitched voices of all the male patients were lowered up to the normal value by the type III thyroplasty.

This article reviews those now available and the situations in which they are useful. A sizing chart is included for easy reference.
Access to the traumatized vertebral artery: an unusual approach
Authors: Lloyd R. V. , O'Flynn P. E. , Jones N. S. 
Published: November 2007

AbstractAlthough injuries to the vertebral arteries are relatively uncommon, there are several different methods used to gain access to these vessels, and to control any bleeding arising from them. We describe a case of torrential oropharyngeal bleeding following a stab wound to the neck in which rapid access to the vertebral artery was gained using a paramedian mandibulotomy; this approach has not previously been documented. The other approaches are discussed.
Auditory rehabilitation in neurofibromatosis type 2: a case for cochlear implantation
Authors: Temple Robert H. , Axon Patrick R. , Ramsden Richard T. , Keles Nesil , Deger Kemal , Yücel Emre 
Published: November 2007

AbstractCochlear implantation has a limited but definite role in the rehabilitation of certain neurofibromatosis type 2 (NF2) patients. The presence of a dead ear either before, or after, tumour removal does not necessarily imply loss of function in the eighth nerve; in some instances the hearing loss will be cochlear. Promontory or round window electrical stimulation may help to identify those individuals with surviving eighth nerve function. In such patients multichannel cochlear implantation promises a better level of audition than the auditory brain stem implant. This paper highlights such a case and the management problems are discussed.
Pharyngo-oesophageal haemangioma with a positive cough impulse
Authors: Hollis L. J. , El-Alami M. , Pyke R. 
Published: November 2007

AbstractBenign tumours of both the pharynx and oesophagus are rarely seen, cavernous haemangiomas even less so. We present a case in which a large lesion was the cause of non-specific symptoms but which only appeared intermittently on nasendoscopic examination of the pharynx.
Tympanostomy in young children with recurrent otitis media. A long-term follow-up study
Authors: Valtonen Hannu , Qvarnberg Yrjö , Nuutinen Juhani 
Published: November 2007

AbstractA total of 305 children, five to 16 months of age, were treated from 1983–1984 with ventilation tubes – Shah vent Teflon tube – inserted under local anaesthesia for recurrent acute otitis media (RAOM) or otitis media with effusion (OME). The final study group comprised 281 children (92.1 per cent) monitored prospectively for five years, 185 in the OME-group and 96 in the RAOM-group. For the first insertion of tubes the average ventilation period was 15.4 months. Re-tympanostomy, with adenoidectomy simultaneously at the first time was performed in 99 ears (35.2 per cent); once in 27.0 per cent, twice in five per cent, and three times in 3.2 per cent. Mastoidectomy due to otorrhoea was performed in three ears (1.1 per cent). The children in the OME-group were at higher risk of repeated post-tympanostomy otorrhoea episodes than children in the RAOM-group. These episodes of otorrhoea during the first insertion of ventilation tubes significantly increased both the tube extrusion rate and the need for subsequent re-tympanostomies. No major complications were caused by the tympanostomy procedure as such. It is concluded that early tympanostomy is a safe procedure in young children with RAOM or OME. However, parents should be carefully informed of risks of post-tympanostomy otorrhoea and recurrent disease after insertion of ventilation tubes necessitating subsequent tube insertion, especially in children with OME.
Temporal bone tumours in patients irradiated for nasopharyngeal neoplasm
Authors: Goh Yau Hong , Chong Vincent F. H. , Low Wong Kein 
Published: November 2007

AbstractRadiation-associated tumours are rare complications of radiotherapy. This study seeks to highlight and discuss the clinically challenging problem of radiation-associated tumours (RATs) in the temporal bones of seven patients previously irradiated for nasopharyngeal neoplasm.Seven patients (six males and one female) with radiation-associated temporal bone tumours are presented (five squamous cell carcinomas, one osteogenic sarcoma and one chondrosarcoma). The initial nasopharyngeal disease for which radiotherapy was indicated was nasopharyngeal carcinoma (six patients) and nasopharyngeal lymphoma (one patient). The latency period between radiotherapy and presentation of temporal bone tumours ranged from five years to 30 years with a mean of 12.9 years. All the patients underwent surgical tumour resection. Three patients had post-operative radiotherapy and one patient underwent pre- and post-perative chemotherapy. Two patients died from the disease within three months of treatment with one patient surviving 36 months at the time of writing. One patient died from an unrelated medical condition three months after surgery.With refinement in radiotherapy techniques and the resultant increase in patient survival, there may be more patients with radiation-associated tumours in the future. It remains imperative for clinicians to be vigilant when patients previously irradiated for nasopharyngeal carcinoma present with otological symptoms as the key to the successful management of this condition lies in the early detection and expedient treatment of this difficult disease.
Diagnosis of peritonsillar infections: a prospective study of ultrasound, computerized tomography and clinical diagnosis
Authors: Scott P. M. J. , Loftus W. K. , Kew J. , Ahuja A. , Yue V. , Van Hasselt C. A. 
Published: November 2007

AbstractPeritonsillar infections include cellulitis and abscess (quinsy). Clinical diagnosis is often supplemented by diagnostic drainage (aspiration or incision) in an effort to distinguish abscess from cellulitis. In a prospective study of 14 patients we have shown that clinical impression alone is unreliable (sensitivity 78 per cent, specificity 50 per cent). Computerized tomography (CT) (sensitivity 100 per cent, specificity 75 per cent) and intraoral ultrasound (sensitivity 89 per cent, specificity 100 per cent) are much more reliable. We propose that intraoral ultrasound could play a useful role in the clinical assessment of peritonsillar infections helping to improve accuracy in distinguishing abscesses from cellulitis.
A third decade's experience with the gastric pull-up operation for hypopharyngeal carcinoma: changing patterns of use
Authors: Hartley B. E. J. , Bottrill I. D. , Howard D. J. 
Published: November 2007

AbstractGastric transposition has been used extensively in this department since 1965 for reconstruction following pharyngolaryngoesophagectomy (PLO). A previous report by Harrison and Thompson in 1986 detailed our experience with 101 cases dating back to 1965. Here we review our experience between 1986–1996.Medical records of 41 cases were examined. The primary site and stage of tumour and associated lymph nodes, patient demographics, complications, in-patient mortality and survival as demonstrated by the Kaplan-Meier method were recorded.Gastric transposition is now used for more extensive tumours: 70 per cent T4 (83 per cent pathologically T4) compared to 21 per cent in the previous report. A high proportion of ‘radiation failures’ remains (54 per cent). The in-hospital mortality has fallen from 11 per cent to seven per cent. The five-year-survival calculated using the Kaplan-Meier method is 11 per cent.This procedure is increasingly being used as a palliative procedure aiming to restore swallowing in the relatively young patient who has very extensive hypopharyngeal carcinoma. Long-term survival rates specific to this operation have fallen. This is attributed to patient selection for the procedure with the vast majority having disease extending into bone, cartilage or soft tissues (T4). The defect created by the resection of less extensive tumours are now increasingly reconstructed with jejunal free flaps and musculocutaneous flaps.
Bilateral synchronous tonsillar carcinoma
Authors: Rajenderkumar D. , Chan K. K. K. , Hayward K. A. , McRae R. D. R. 
Published: November 2007

AbstractSynchronous cancers occur in four per cent of patients with head and neck malignancies but no bilateral synchronous tonsillar carcinomas have been described in the English literature. We describe the first such case and discuss the prognostic aspect of this carcinoma. In the presence of contralateral neck nodes in patients with head and neck malignancies, a careful search should be made for a second head and neck primary.
A review of heterotopia and associated salivary gland neoplasms of the head and neck
Authors: Ferlito Alfio , Bertino Giulia , Rinaldo Alessandra , Mannarà Giacinto M. , Devaney Kenneth O. 
Published: November 2007

AbstractSalivary tissue neoplasms may involve normal, accessory and heterotopic salivary gland tissue. A case of Warthin's tumour originating from heterotopic salivary gland tissue of the upper neck is reported. The radioactive uptake of131I, evidenced in the neck mass in its pre-diagnostic assessment, suggested a diagnosis of cervical node involvement from a primary malignant thyroid neoplasm. A critical review of the literature on heterotopic salivary gland tissue neoplasms of the head and neck is also presented.
Clarion® cochlear implants: surgical implications
Authors: Filipo R. , Barbara M. , Monini S. , Mancini P. 
Published: November 2007

AbstractThe surgical aspects of 34 Clarion® cochlear implants, positioned during a five-year period on 31 profoundly-deaf subjects as primary (11 children, 20 adults) and revision surgery (one child, three adults) were taken into consideration. Intra-and post-operative complications related to the specific structure of this device were considered along with the benefits obtained by update of the hardware and surgical approach. A smaller thickness of the internal receiver as well as the shifting from a retro-auricular/subtemporal (RA-ST) to an endaural-retromastoid (EA-RM) approach have contributed to a dramatic drop in post-operative complications, such as skin defect or device extrusion. Special care should, however, be taken when cochlear implantation is planned in ears with chronic otitis or its surgical sequelae. From the two revised cases (hardware failure, electrode displacement) in whom re-implantation in the same side was performed, it has been demonstrated that the helicoidal shape of the electrode carrier is not inducing any additional trauma to the cohlear structure.

Published: November 2007

AbstractAn unusual case of encephalocele causing obstruction of the upper airway in a neonate is described. The patient presented with a large mass in the neck, which extended from the base of the skull to the level of the larynx. Although there was no evidence of a defect of the skull base, subsequent excision and histological examination confirmed an encephalocele.
Primary osteogenic sarcoma of the tongue
Authors: Dubey S. P. , Murthy D. P. , Cooke R. A. , Chaudhuri D. 
Published: November 2007

AbstractA 56-year-old man presented with the difficulty of swallowing and respiratory distress due to a large tumour arising from the tongue and occupying the entire oral cavity. Histological examination revealed it to be an extraskeletal osteogenic sarcoma. The tumour was excised. After six weeks, he came back with massive local recurrence and bleeding from the tumour, but died despite chemotherapy. Review of the literature revealed only four other such cases of this rare tumour. A brief review of these four cases is also made.
Factors affecting hearing results after stapes surgery

Published: November 2007

AbstractFactors affecting auditory improvement after stapes surgery were investigated retrospectively on a study group of 106 otosclerotic ears (86 subjects). While the closure of the air-bone (A-B) gap after surgery was good at 2 kHz and 4 kHz, it was poor at 8 kHz and at frequencies lower than 1 kHz. Under 1 kHz, the lower the frequency, the worse the A-B gap after surgery. Stapedotomy and partial stapedectomy showed better post-operative hearing gain at 4 kHz than total stapedectomy. Total stapedectomy scored significantly better at 250 Hz and 500 Hz than stapedotomy. There was a close relationship between the pre-operative and post-operative A-B gap at frequencies under 1 kHz. The smaller the pre-operative A-B gap, the better the closure of the post-operative A-B gap at frequencies under 1 kHz. The smaller the pre-operative A-B gap, the better the closure of the post-operative A-B gap at these frequencies. It was speculated that otosclerotic ears with a larger pre-operative airbone gap might have another lesion in the middle ear other than the oval window.
Vocal fold paralysis following carotid endarterectomy

Published: November 2007

AbstractInjury to the vagus nerve or one of its branches during carotid endarterectomy (CEA) can result in vocal fold paralysis (VFP). This study assessed prospectively 73 patients undergoing CEA. A total of 76 procedures were performed in these patients over a one-year period. All patients underwent preoperative and post-operative assessment of vocal fold mobility by indirect laryngoscopy and/or flexible nasendoscopy. All patients had normal vocal fold mobility pre-operatively. Eight patients (10 per cent) complained of hoarseness after surgery and in three patients (four per cent) examination confirmed an ipsilateral VFP. This persists in all three patients at six-month follow-up. Vocal fold assessment is important in patients undergoing CEA, particularly when performing second side surgery. We recommend that patients should be informed of the risk of VFP following CEA when obtaining consent.

Authors: Srinivasan V. , Deans J. A. J. , Nicol A. 
Published: November 2007

AbstractSchwannomas, arising from the Schwann cells of the nerve sheath, occur very rarely in the sino-nasal tract and histological diagnosis can, sometimes, be difficult. We describe a case of schwannoma of the sphenoidal sinus occurring in a 71-year-old man, who underwent complete excision of the tumour endoscopically. To our knowledge, this is the third case of sphenoid sinus schwannoma reported in the English literature.
Tracheo-oesophageal puncture by retrograde passage of a gastroscope via mini-laparotomy and gastrotomy
Authors: Loughran S. , McKee G. , Carding P. 
Published: November 2007

AbstractSecondary tracheo-oesophageal puncture is frequently used for voice restoration after laryngectomy. A method utilizing a flexible gastroscope passed via a mini-laparotomy and gastrotomy in a retrograde manner is described in a patient where extensive pharyngeal resection made it impossible to cannulate the upper aerodigestive tract. The patient suffered minimal morbidity and produced reasonable speech.

Published: November 2007

AbstractA case of melanotic neuroectodermal tumour of infancy is decribed. The pre-operative diagnosis was made on cytological material obtained by fine needle aspiration. The patient was a three-month-old male infant with a rapidly growing maxillary tumour mass that also involved the pterygomaxillary fossae and the floor of the orbit. In addition to the typical clinical presentation, the cytology is also distinctive showing a dual population of small neuroblastic cells and large melanin-containing epithelial cells. Histological, immunohistochemical and electron microscopic examination of the excised mass confirmed the initial diagnosis. The pre-operative distinction of this tumour from other small round cell tumours of infancy (rhabdomyosarcoma, neuroblastoma, melanoma and lymphoma), is essential in order to plan the most complete resection therefore reducing the possibilities of tumour recurrence. This tumour belongs to a field of pathology with which many otolaryngologists may not be familiar.
CO2and KTP-532 laser cordectomy for bilateral vocal fold paralysis
Authors: Manolopoulos L. , Stavroulaki P. , Yiotakis J. , Segas J. , Adamopoulos G. 
Published: November 2007

AbstractLaryngeal obstruction due to bilateral vocal fold paralysis has been treated in many different ways. The CO2laser or KTP-532 laser endoscopic cordectomy described in this report is a slight modification of the posterior partial cordectomy proposed by Dennis and Kashima. This technique was used in 18 patients (14 with the CO2and four with the KTP-532 laser). Prophylactic tracheostomy was performed preoperatively. Post-operative results were excellent in nine cases, good in seven cases and poor in two cases who had to remain with a permanent tracheostomy tube with a speaking valve. The main complications noted were the formation of a granuloma (seven cases) and arytenoid oedema (six cases). Revision surgery was performed in the seven cases with granuloma formation and in the two with persistent oedema. The results and the post-operative findings from the use of the two lasers were similar.
Paediatric tracheostomy: an analysis of 40 cases
Authors: Dubey S. P. , Garap J. P. 
Published: November 2007

AbstractTracheostomy in the paediatric patient has been associated with significant morbidity and mortality compared to that in the adult. A retrospective analysis was made of 40 patients up to the age of 12 years having tracheostomies. Upper airway obstruction made up the commonest (32 patients, or 80 per cent) indication for paediatric tracheostomy in our series where males slightly outnumbered females. The majority (31 patients, or 77.5 per cent) underwent the operation under general anaesthesia with endotracheal intubation. Thirty-four (85 per cent) patients underwent ‘planned’ tracheostomies and six (15 per cent) underwent ‘crash’ procedures. Thirteen (32.5 per cent) patients were under the age of one year when tracheostomies were performed. The maximum duration of tracheostomies was between one week to within a month and after one month to within three months; each containing 11 (27.5 per cent) patients.Sixty-four different surgical procedures were performed on these patients in which laryngoscopy and bronchoscopy were the commonest procedures. Nine (22.5 per cent) had early post-operative and 14 (35 per cent) had late post-operative complications. Among these 40 children with tracheostomies, one (2.5 per cent) died due to a tracheostomy-related cause and 10 (25 per cent) due to the primary disease process itself. Tracheostomies performed to provide access for general anaesthesia for other surgical procedures were associated with a better prognosis.
