Local anaesthesia in flexible nasendoscopy. A comparison between cocaine and co-phenylcaine
Authors: Lennox P. , Hern J. , Birchall M. , Lund V. 
Published: November 2007

AbstractFlexible nasendoscopy is now an integral part of the diagnostic process in Otorhinolaryngology. Topical local anaesthesia is generally recommended and cocaine is usually the drug of choice in view of its concurrent vasoconstrictor action. However, it is expensive, a controlled drug and serious side effects have been reported. Co-phenylcaine forte is a new preparation which also has both local anaesthetic and vasoconstrictor properties. This study compares the efficacy of cocaine and Co-phenylcaine in flexible nasendoscopy and concludes that they provide similar local anaesthesia and vasoconstriction of the nasal mucosa. Co-phenylcaine forte can therefore be used as an alternative to cocaine in flexible nasendoscopy.
Correlation between clinical response and injection quality in treatment of spasmodic dysphonia
Authors: Tewary A. K. 
Published: November 2007

AbstractBotulinum toxin injection is an effective treatment for spasmodic dysphonia. There are ethical difficulties in performing a controlled placebo trial to assess the effectiveness of this treatment. This paper shows a significantly decreased clinical response following technically poor injections given to patients who respond well to good quality injections.
Surgical management of the plunging ranula: a review of seven cases
Authors: Ichimura Keiichi , Ohta Yasushi , Tayama Niro 
Published: November 2007

AbstractWe have treated seven patients with a plunging ranula during the past 10 years. All patients underwent surgery via a cervical approach. In two, the ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle, while in the other five the plunging ranula passed posteriorly to the mylohyoid muscle. A pseudocyst was extirpated in each patient. Although total sublingual gland excision was not performed in two patients, no recurrence was observed in any patient. Incision of the pseudocyst facilitated subsequent procedures and decreased the incidence of transient facial paralysis. In the presence of a cervical mass without swelling of the oral floor, a cervical approach may still be the method of choice either for the first operation or for salvage surgery after recurrence subsequent to intraoral procedures. It is based on the fact that there may be ectopic sublingual glands residing on the inferior surface of the mylohyoid muscle.
Incidence of previously undetected disease in routine paediatric otolaryngology admissions
Authors: Zeitoun H. , Robinson P. 
Published: November 2007

AbstractThe process of clerking routine pre-operative admissions involves the house officer taking a full medical history and performing a full physical examination. The diagnostic yield is thought to be low, and the educational value to the house officer is also small. This study addresses the question as to whether routine physical examination is always indicated.One hundred and nine children admitted for routine Otolaryngology procedures were prospectively studied to identify the importance of examination in the pre-operative assessment of patients.The results showed that 51 per cent of the children admitted had risk factors. The medical history was sufficient to identify these risk factors in all patients with the exception of one cardiac condition.This study concludes that a suitable alternative to the current process of clerking such as a standardized nurse history could be safely and efficiently undertaken. Eliminating the tiny percentage of previously unrecognized disease would be a prerequisite for such a change.
Solitary fibrous tumour of the infratemporal fossa
Authors: Rayappa C. S. , McArthur P. D. , Gangopadhyay K. , Antonius J. I. 
Published: November 2007

AbstractSolitary fibrous tumour was first described as a pleural tumour. It has been reported in a number of extrapleural sites including the head and neck. We present the first case of solitary fibrous tumour of the infratemporal fossa described in the English literature. Complete excision was achieved using the orbitozygomatic infratemporal craniotomy approach.
Configuration of experimentally produced cholesteatoma by transplantation of a free skin graft
Authors: Gyo Kiyofumi , Sasaki Yasushi , Hinohira Yasuyuki 
Published: November 2007

AbstractResidual cholesteatoma was experimentally produced in guinea pigs by transplanting a free skin graft into the middle ear bulla. In group A, the graft was placed on the mucosa after scratching the surface with a pick, while in group B, it was placed on the bone surface following removal of the mucosa and drilling with a diamond burr. The group A procedure was conducted on the left ear and the group B procedure on the right ear in 12 guinea pigs. The animals were sacrificed at two, four and eight weeks after transplantation. In all 12 ears of group A, the graft kept its original flat shape, resembling an open type residue. In eight of 12 ears of group B, the graft grew forming a squamous pearl, while in the remaining four ears it retained a flat shape. The difference in configuration is thought to be due to the amount of granulation around the graft.

Authors: Al-Sader M. H. , Tait R. , Leader M. 
Published: November 2007

AbstractWe report a case of primary chondroblastoma presenting as a submucosal lump on the nasal bridge of a 15-yearold female. The lesion was curetted and the patient remains well after one year follow-up. This case report describes a primary chondroblastoma arising in an unusual site and in an unusual age group.
The history of percutaneous tracheotomy
Authors: Ernest van Heurn L. W. , Brink Peter R. G. 
Published: November 2007

AbstractPercutaneous tracheotomy is a surgical procedure for inserting a tracheal cannula into the tracheal lumen without a large incision, without extensive dissection of pretracheal tissue and without exposure of the trachea. Ciaglia's report on the procedure a decade ago led to this technique gaining popularity, although its origin is much older.
Maxillary antral lavage using inferior meatal cannula anaesthesia
Authors: Mochloulis G. , Hern J. D. , Hollis L. J. , Tolley N. S. 
Published: November 2007

AbstractAntral puncture and lavage through the inferior meatus is a minor but common otolaryngological procedure, usually performed under local anaesthesia. We describe a new method of introducing local anaesthetic into the inferior meatus, via the use of a soft intravenous cannula connected to a syringe containing 10 per cent cocaine paste. We have called this new technique inferior meatal cannula anaesthesia (IMCA).
Electrodissection tracheotomy
Authors: Alvi Aijaz , Stegnjajic Arsen 
Published: November 2007

AbstractThe acquired immune deficiency syndrome (AIDS) epidemic and other potentially fatal blood-borne infectious diseases have produced a heightened awareness for preventing accidental inoculation of surgeons and operating theatre staff. It is incumbent upon the head and neck surgeon to use safe and effective surgical technique in these patients to prevent such an event. We are seeing an increasing number of patients with AIDS and hepatitis undergoing tracheotomy. We present a sharps-free technique for tracheotomy which is safe for the hospital staff and the patient.
Bilingual hearing acquisition in Welsh and English following cochlear implantation
Authors: Osborne Jonathan , Jenkins Janet , Sparkes Clive 
Published: November 2007

AbstractA post lingually deafened adult equilingual in Welsh and English, received rehabilitation in both languages following cochlear implantation.Hearing acquisition was very similar in both languages, indicating that there is no need to vary the electrode coding strategy for different languages of Indo-European origin. The situation may be difficult for tonal languages such as Chinese.
Facial paralysis caused by a lymphoepithelial cyst located in the parotid gland
Authors: Watts S. J. , Turner N. O. , Juan J. San , Rockley T. J. 
Published: November 2007

AbstractWe report the case of an acute onset facial paralysis which was caused by a benign lymphoepithelial cyst found in the parotid, an association which is a rarity in the literature. The diagnosis and surgical management is discussed. This report emphasises the clinical principle that parotid masses causing an acute facial palsy are not necessarily malignant in nature. Intra-operative frozen section histology is helpful in saving the patient from unnecessarily radical surgery.
Isolated sphenoid sinus changes – history, CT and endoscopic finding
Authors: Hadar Tuvia , Yaniv Eitan , Shvero Jacob 
Published: November 2007

AbstractThis study reviews the records of 21 patients with isolated sphenoid sinus disease who were treated by rigid endoscopic sphenoidotomy at the Nose and Sinus Unit, Department of Otolaryngology of Beilinson Medical Center, Israel.Diagnosis was made on the basis of history, rigid nasal endoscopy and computed tomography (CT) scan. The most frequent symptom was headache; no instances of ‘pathognomonic’ headache were found. Sphenoidotomy was performed through the area of the natural ostium. The pathological finding was infection in 11 patients, cyst in four patients, polyps in three patients, mucocoele in two, and inverted papilloma in one patient.Surgical results were very good. Endoscopic sphenoidotomy proved to be safe, with minimal blood loss, reduced operating time, decreased morbidity, and short post-operative hospitalization.
Otoplasty: the problem of the deep conchal bowl
Authors: Beasley N. J. P. , Jones N. S. 
Published: November 2007

AbstractThe correction of prominent ears requires a logical approach to address each of the anatomical defects present while bearing in mind the overall shape of the ear. The two most common problems encountered are the lack of an antihelix and a deep conchal bowl.We describe a method of reducing the depth of the conchal bowl which avoids some of the problems previously encountered such as occlusion of the external auditory meatus and visible irregularity on the external surface of the pinna. Resection of the inferomedial part of the conchal bowl and thinning of the ponticulus allow realignment of the ear and prevent prominence of the antitragus. The ear is then secured with concha-mastoid sutures and the scapha-conchal angle can then be corrected to form an antihelix if necessary.
Hodgkin's disease of middle ear and mastoid
Authors: Solanellas J. , Esteban F. , Soldado L. , López-Lacomba D. , Hierro C. , Jimenez J. M. 
Published: November 2007

AbstractWe present a case of Hodgkin's disease of the mastoid associated with upper cervical lymph node involvement without disseminated disease. This patient was treated with chemotherapy alone and lesions responded rapidly. At present the patient is well, with no evidence of recurrence or extension of this disease. Hodgkin's disease of the middle ear and mastoid is an extremely rare disease. After a wide search in the literature no cases of Hodgkin's disease arising in the middle ear and mastoid have been found.
Dural metastasis at medulla oblongata: a rare cause of vocal fold paralysis
Authors: Pak Martin Wai , Mak Henry Ka Fung , Ku Peter Ka Ming , van HasseltS Charles Andrew 
Published: November 2007

AbstractMalignancy is a major cause of vocal fold paralysis. Nevertheless, metastatic disease at the brainstem leading to high vagal paralysis is rarely encountered. We illustrate an unusual case of unilateral vocal fold paralysis caused by dural metastasis directly compressing on the nucleus ambiguus. The median position of the paralysed vocal fold is inconsistent with the Wagner and Grossman theory predicting the location of the lesion.
Castleman's disease restricted to the infratemporal fossa
Authors: Rodrigo Juan P. , Fernandez Jose A. , Alvarez Juan C. , Gómez Justo , Suárez Carlos 
Published: November 2007

AbstractGiant lymph node hyperplasia (Castleman's disease) is usually reported as a solitary mediastinal tumour, although involvement of other anatomical sites and a multicentric form have been reported. We describe a rare case of Castleman's disease due to its localisation (the left infratemporal fossa) and histology (plasma-cell variant). A brief review of the main clinico-histological characteristics of Castleman's disease is also presented.
Increase in epithelial mast cell numbers in the nasal mucosa of patients with perennial allergic rhinitis
Authors: Slater A. , Smallman L. A. , Drake-Lee A. B. 
Published: November 2007

AbstractThe aim of the study was to compare the numbers and distribution of mast cells in the nasal mucosa of perennial allergic rhinitis (PAR) patients and controls, as demonstrated by different staining methods for light microscopy.Biopsies of inferior turbinate mucosa were taken from 10 patients with PAR and 10 patients undergoing septoplasty or septorhinoplasty (control group). Sections for light microscopy were stained with azure A, chloroacetate esterase and an ABC immunohistochemical technique using antibody to tryptase.Three times more mast cells were found in the epithelium of PAR patients compared to controls using the immunohistochemical technique (p= 0.0074). This method demonstrated considerably more mast cells than the other stains.The increase in epithelial mast cells is consistent with the migration of mast cells seen in seasonal allergic rhinitis, and this may be important in the phenomenon of nasal priming seen after repeated antigen exposure.

Published: November 2007

AbstractOur aim was to analyse the dynamics of healing processes in the nose and oesophagus by videoendoscopic examination and reconstruction of the natural dynamics and continuity of a process using modern computer technology and so-called morphing software. Thirteen patients were followed-up for six months after sinus surgery and three weeks after oesophagitis. Four overlapping and meshing phases of wound healing following sinus surgery with significant interindividual differences. Topical budesonide shortened the duration of wound healing phases. Healing of oesophagitis occurred approximately symmetrically from the wound edges to the centre with constant velocity. Computer-assisted morphing enables dynamic analysing of mucosal processes under the following preconditions: Availability of a valid imaging method for documentation and measurement with the generation of congruent images. The process under analysis must run without sudden leaps and there must be adequate choice of timing of single measurement procedures.
Arytenoidopexy for bilateral vocal fold paralysis in young children
Authors: Triglia Jean-Michel , Belus Jean-François , Nicollas Richard 
Published: November 2007

AbstractThe purpose of this retrospective study was to describe and evaluate the results of arytenoidopexy performed by the external laterocervical approach in 15 consecutive children presenting bilateral vocal fold paralysis causing life-threatening airway compromise. Mean age at the time of surgery was 20 months and mean follow-up was 42 months. At the end of follow-up all patients were in good health and did not need special care for breathing. No abduction movement has been observed on the opposite vocal fold since arytenoidopexy. One failure subsequently required arytenoidectomy. The findings of this study suggest that arytenoidopexy is an effective surgical treatment for life-threatening bilateral vocal fold paralysis in young children.
Are laryngeal papilloma virus-infected cells viable in the plume derived from a continuous mode carbon dioxide laser, and are they infectious? A preliminary report on one laser mode
Authors: Kunachak Somyos , Slthisarn Pranee , Kulapaditharom Boonchu 
Published: November 2007

AbstractThe purpose of this study was to determine the potential risk of transmitting viable viral infected cells as well as viral infectivity of laryngeal papilloma in the plume derived from a continuous mode carbon dioxide laser. Each of 10 juvenile recurrent laryngeal papilloma specimens was divided into two equal parts, and one part was irradiated with a carbon dioxide laser employing a continuous mode at the power setting of 10 watts with 0.5 mm spot size and a power density of 1667 W/cm2. The resultant laser plume was trapped and was cultured simultaneously with the other part of the specimen which served as the control. All irradiated specimens tested yielded negative culture results while all the control counterparts revealed viable cell growth. To detect the viral infectivity, laser plume was cultured with two separate cellsystems, one was the porcine PS clone D cell line and the other normal mucosal cells obtained from the same patient, and to control these systems both cell lines were also designed to be infected with polio virus. Both cell lines in the viral infectivity testing systems revealed no sign of viral infection. The results suggest that papilloma virus-infected cells cannot survive the continuous mode of carbon dioxide laser irradiation. We primarily conclude that, to avoid airborne transmission of plume containing laryngeal papilloma viral-infected cells and infectious viral particles, the carbon dioxide laser parameters should be in a continuous mode with the power density equal to, or more than, 1667 W/cm2.
Menière's disease: evolution of a definition
Authors: Beasley N. J. P. , Jones N. S. 
Published: November 2007

AbstractIn 1861 Prosper Menière separated patients with episodic vertigo, hearing loss and tinnitus from a group previously described as having apoplectiform cerebral congestion. He suggested the cause was disease within the semicircular canals (Menière, 1861). Over the years it becoame apparent that within this group there were a number of patients with characteristic signs and symptoms and in 1938 a pathological correlate was found in the form of endolympatic hydrops. Descriptions scuh as Menière's ‘Menière's ‘disease’, Menière's ‘syndrome’ and Menière' ‘symptom complex’ led to a confusing array of terms for this condition and monotoring of treatment results became difficult. In response to this in 1972 the American Academy of Ophthalmology and Otolaryngology and Otolaryngoly Committee on Hearing and Equillibrium published a clear definition of Menière's disease and criteria for the reporting of treatment results, it was updated in 1985 and again in 1995. We described the changes that have taken place as the definition of Menière's disease has evolved.
Nuclear DNA content using computerized image cytometry of squamous cell carcinomas of the head and neck

Published: November 2007

AbstractPloidy status using flow cytometry of head and neck cancers may be of prognostic value. We describe the use of image cytometry in ploidy measurement of squamous cell carcinomas of the head and neck (SCCHN). This technique allows only tumour cells to be measured, thereby rejecting debris, artefact and benign cells. Tissue sections were cut from tumours and then Feulgen stained. A total of 60 patients were included in this study, 23 females and 37 males. The data reveals a relationship between ploidy status and the histological differentiation. However, the ploidy status and histological differentiation do not appear to correlate to the clinical stage of the disease. This method of measuring ploidy may be more accurate than flow cytometry and may have a prognostic role in head and neck cancer patients. A study comparing both methods may demonstrate this and we aim to evaluate this in the future.
Primary branchial cleft carcinoma – a case report

Published: November 2007

AbstractPrimary branchial cleft carcinoma is a diagnostic challenge. The majority of cases have been shown, following the application of rigid criteria, to have developed from an occult metastasis elsewhere.We describe what we believe to be only the second reported case in a patient who fulfils all of the established criteria.

Published: November 2007

AbstractVagal paraganglioma is a rare usually benign tumour of neural crest origin. The malignant form of this tumour i s very uncommon and the diagnosis is made on the basis of its clinical behaviour rather than its histological appearance. We report a case of vagal paraganglioma metastatic to adjacent cervical nodes and discuss the diagnosis and management of this tumour.

Authors: Myatt H. M. , Remedios D. 
Published: November 2007

AbstractThe case of a 75-year-old lady with a large parapharyngeal pleomorphic adenoma excised via a transpalatal peroral technique is presented. This is a new approach to the parapharyngeal space not previously described. A laterally placed full thickness soft palate split from the superior pole of the tonsil to 1 cm proximal to the pterygoid hamulus provided good surgical access to the whole length of the parapharyngeal space and allowed complete tumour excision with minimal morbidity.

Published: November 2007

AbstractThe hearing function of 50 children with bacterial meningitis was evaluated at the second and 10th days, and eight weeks after admission with auditory brain system responses (ABR) to investigate whether meningitis causes hearing loss. Normal values were obtained in all tests from both ears of 24 patients (48 per cent). Twelve patients (24 per cent) had temporary, and seven (14 per cent) patients had persistent mild degree hearing loss. Severe hearing loss was detected bilaterally in five (10 per cent) patients and unilaterally in two (four per cent) patients. Patients with other complications such as subdural effusion, convulsion, brain oedema and paralysis were found to have a higher incidence of hearing loss. We observed that patients treated with dexamethasone had 7.7 per cent persistent hearing loss, 11.6 per cent mild hearing loss, 34.6 per cent transient hearing loss, but in the group who did not receive dexamethasone there was 19.2 per cent persistent hearing loss, 15.3 per cent mild hearing loss and 11.6 per cent transient hearing loss. There were other signficant differences between the two groups in restoration of normal body temperature, the CSF/plasma glucose concentration ratio was elevated, CSF (cerebro-spinal fluid) protein concentration was decreased and the cell count in the CSF was decreased in the dexamethasone group, significantly more than the group who were not receiving dexamethasone. The hearing loss tended to be more frequent among younger children.
