Metastatic seminoma of the sphenoid sinus
Authors: Andaz C. , Alsanjari N. , Garth R. J. N. , Dearnaley D. P. 
Published: November 2007

AbstractMetatastic tumour of the sphenoid sinus from distant primary sites are rare. If sphenoid involvement from adjacent structures is excluded there have been 26 reported cases of metastatic sphenoid sinus tumours. Seminoma metastatizing to other paranasal sinuses has been reported but a careful literature search did not reveal this occurring previously in the sphenoid sinus.
Cervical cord compression complicating tracheo-oesophageal puncture
Authors: Diver J. P. , Murty G. E. , Bradley P. J. 
Published: November 2007

AbstractTracheo-oesophageal puncture for voice restoration is now established as a common procedure in the postlaryngectomy patient. We present what we believe to be the first recorded case of osteomyelitic cervical cord compression following this technique. This is a potentially fatal complication, but diagnosis and active surgical intervention can result in recovery of full neurological function.
Tinnitus related to eyelid blinking
Authors: Rajah V. 
Published: November 2007

AbstractTinnitus due to muscular causes is rare. The commonest pathological muscular cause of tinnitus is palatal myoclonus.A case of bilateral tinnitus, related to eyelid blinking, is presented. This is the first case reported in the literature. Previous reported cases of tinnitus related to eyelid blinking have all been unilateral and associated with recovery from a VII nerve palsy. The treatment of the condition is discussed.

Published: November 2007

AbstractRhinocerebral mucormycosis is a rapidly fatal fungal disease which involves the nose, paranasal sinuses, orbit and central nervous system. The fungal infection is usually secondary to immunosuppression, diabetic acidosis, or antibiotic, steroid or cytotoxic therapy. It can also occur in patients suffering from burns, malignancy and haematological disorders. Current treatment consists of correction of the underlying disorder, repeated debridement of the wound in combination with intravenous amphotericin B.This paper describes our experience with a case of rhinocerebral mucormycosis. This is an unusual case in which mucormycosis was seen in a young female where no underlying cause was found. She responded to surgical debridement in combination with intravenous amphotericin B.
Ossifying pleomorphic adenoma of the maxillary antrum
Authors: Lee K. C. , Chan J. K. C. , Chong Y. W. 
Published: November 2007

AbstractAn unusual case of pleomorphic adenoma with exuberant bone formation, occurring in the maxillary antrum of a 21-year-old male and showing repeated recurrence, is reported. In contrast to the endochondral ossification in the previous reported cases of pleomorphic adenoma, direct deposition of osteoid by metaplastic myoepithehal cells is suggested to explain the bone formation. The difficulties of distinguishing this tumour from osteosarcoma during intraoperative diagnosis are discussed.
Pitfalls in the follow-up of cervical and mediastinal goitres: role of CT imaging
Authors: Cohen Ohad , Herskovitz Pearl , Shindell Bella , Leiba Sara , Hadar Herzlia 
Published: November 2007

AbstractFour patients with cervical and mediastinal goitres were described. Routine investigation in these patients, including chest X-rays, oesophageal and tracheal X-rays and scintigraphy of the thyroid gland, failed to show significant changes over the years, or underestimated the true extent of the goitres. Three of the goitres caused severe mediastinal compression, evident only on computed tomography (CT) imaging, and requiring urgent surgery. The pros and cons of different diagnostic modalities for imaging cervical and mediastinal gotires are discussed, stressing the importance of CT imaging as exemplified in the cases presented.
Unusually large mastoid antrum (‘mega antrum’)
Authors: Puranik K. R. , Murthy P. S. N. , Gopalakrishna Ramesh , Nayak D. R. 
Published: November 2007

AbstractPatients who present with a unilateral non-tender bony swelling in the mastoid region without any clinical evidence of middle ear infection could be diagnosed as having a fibrous or bony lesion affecting the temporal bone. In such cases, if there is radiological evidence of large lucent area in the mastoid antrum without any bony dehiscence one should keep in mind in the differential diagnosis a mega antrum in addition to congenital cholesteatoma and eosinophilic granuloma. A large lytic lesion in the mastoid segment of the temporal bone with an intact tympanic membrane therefore presents a diagnostic dilemma. A case of an unusually large mastoid antrum in an young adult with no middle ear suppuration and a cosmetically unacceptable swelling behind the ear is presented.
Multimodality treatment in stage IV squamous cell carcinoma of the head and neck. A long-term follow-up
Authors: Klima A. , Bergmann I. , Szepesi S. 
Published: November 2007

AbstractWe treated 114 patients with advanced inoperable head and neck cancer with a combined-modality protocol that included two cycles of chemotherapy followed by radiotherapy or three cycles of chemotherapy and in 18 patients with a radiosensitizing agent. At the beginning of the treatment all but one patient presented with a stage IV cancer. With a follow-up of 42–58 months, four patients are alive (three from the radiosensitizing group and one of the chemotherapy group). Complete response after the radiosensitizing agent correlated with superior prolonged disease-free survival in comparison to complete responses after chemotherapy at the level of p<0.009.
Eustachian tube function in sudden hearing loss and in healthy subjects
Authors: Maier Wolfgang , Hauser Rolf , Münker Gerd 
Published: November 2007

AbstractThe relationship between sudden hearing loss and an ipsilateral patulous tube was tested in ourEustachian tube laboratory. Fifty patients suffering from sudden hearing loss were examined by the pressure chamber impedance method, giving objective data on Eustachian tube function. Results were compared to those obtained from 56 healthy volunteers in a preceding investigation. Ourinvestigation did not show any associations between patulous tube syndrome and sudden hearing loss, as had been claimed by several authors previously. There was even indication of a decreased patency of Eustachian tube in our patients in active and passive tubal tests. We could demonstrate a high reproducibility of values obtained by our method, indicating that results are representative in healthy persons as well as in patients.In a case report the importance of objective diagnostic methods in differential diagnostics of Eustachian tube pathology is emphasized.
Temporal bone histopathological findings in campomelic dysplasia
Authors: Takahashi H. , Sando I. , Masutani H. 
Published: November 2007

AbstractBoth temporal bones of a newborn (35 gestational weeks old) with campomelic syndrome were studied histopathologically. This is to our knowledge the second temporal bone report (third case) of this syndrome. The findings included: abnormal cartilagenous and osseous tissues and abnormality in the globuli interossei in the otic capsule; deformities of the vestibule and semicircular canals, probably due to compression by the abnormal cartilaginous tissue; hypoplastic cochleaand semicircular canals; aberrant course of the facial nerve; wide dehiscence of the facial canal in the tympanic portion; slight hypoplasia of the malleus and anomalies in the incus and stapes; and large epitympanic space. These findings closely resembled those of the first report, and suggest that: 1) campomelic dysplasia is a definite disease entity with consistent pathogenesis, and 2) similar otologic manifestations may be expected in the majority of patients with this syndrome.
Prognosis in mouth cancer: host factors
Authors: Stell P. M. 
Published: November 2007

AbstractA personal series of 842 patients with a tumour of the oral cavity is presented. Five hundred and twelve of these patients had a histologically proven squamous cell carcinoma, and were previously untreated.Increasing age was associated with worsening performance status. Women were older at presentation than men, and tumours of the upper part of the mouth were more common in the elderly, but there was no relation between age and histological grade or stage grouping.Sex had no correlation with performance status or histological grade. However, men were more likely to have an advanced tumour, and tumours of the floor of the mouth and alveolus were much commoner in men.There was no correlation between performance status and site or histological grade, but patients in poor general condition were more likely to have stage III-IV tumours.Multivariate analysis showed that sex had no impact whatever on survival, but survival fell with increasing age and worsening performance status. The effect of age and performance status disappeared when the survival of treated patients was adjusted for deaths due to other causes.
The role of electron microscopy in the diagnosis of tumours of the Head and neck
Authors: Fisher C. , Flood L. M. , Ramsey A. D. 
Published: November 2007

AbstractA four-year study was undertaken to determine the value of electron microscopy in the diagnosis of head and neck tumours. During this period 80 samples were submitted for examination, of which 69 contained assessable tumour. Electron microscopy made a major contribution to the diagnosis in 25 cases (36 per cent). Areas in which ultrastructural examination was of diagnostic significance included the precise categorization of apparently undifferentiated carcinoma and the identification of melanomas. Little diagnostic benefit was gained from electron microscopic examination of thyroid, lymphoid or salivary gland neoplasms. The value of electron microscopy in relation to immunohistochemistry is discussed.

Published: November 2007

AbstractA 53-year-old male patient had been suffering from severe aural symptoms (pulsatile right-sided tinnitus and paroxysmal dizziness attacks with nausea) and right hemifacial spasm. Treatment had involved stellate ganglion block with lignocaine and the injection of intravenous sodium bicarbonate solution for attacks of Meniere's syndrome and facial nerve block with lidocaine for hemi-facial spasm. Despite these treatments, the dizzy attacks became more frequent, developing into the clustering state. Air CT cisternography and vertebral angiography demonstrated an enlarged and curved vertebral artery. Vascular cross-compression of the Vllth and VHIth cranial nerves was therefore suspected. Microvascular decompression was performed. After operation, the pulsatile tinnitus, dizziness and hemifacial spasm disappeared. From the present case and a review of the literature, we conclude that vascular cross-compression of the VHIth cranial nerve should be an indication for microvascular decompression only when symptoms of vascular cross-compression of the Vllth cranial nerve are also seen.
Combined internal maxillary and anterior ethmoidal arterial occlusion: the treatment of choice in intractable epistaxis
Authors: Singh Bharath , Med M. 
Published: November 2007

AbstractWhilst it is generally accepted that the standard management for anterior or benign epistaxis is either cautery or anterior nasal packing, that of posterior or intractable epistaxis remains controversial. Various modalities of treatment, ranging from posterior nasal packing to arterial ligation and embolization, have been advocated but none have been unanimously accepted as the treatment of choice.The purpose of this paper was to determine the efficacy of internal maxillary arterial ligation versus combined internal maxillary arterial ligation and anterior ethmoid arterial coagulation in intractable epistaxis.Over a six year period, from 1985 to 1990,454 patients were admitted and treated for epistaxis. Forty-seven patients were diagnosed as having intractable epistaxis on the basis that the epistaxis failed to settle on anterior nasal packing. They were moved to the next step in management, which was combined anterior and posterior nasal packing. There were 30 failures, one was found to have choriocarcinoma of the maxilla, and was treated wtih cytotoxics, and the other 29 were moved to the next step, which was arterial ligation. Fifteen patients had internal maxillary arterial ligation, and 14 combined internal maxillary arterial ligation and anterior ethmoidal arterial coagulation.Large windows were created in both the anterior and posterior walls of the maxillary sinuses and all identifiable branches of the internal maxillary artery were dissected out carefully and two medium size ligating clips were placed over the main trunk, the sphenopalatine and the descending palatine branches. Single clips were placed on all other identifiable branches. Coagulation of the anterior ethmoidal artery was performed with a bipolar cautery. There were three (20 per cent) failures in the internal maxillary arterial ligation group and none in the combined internal maxillary arterial ligation and anterior ethmoidal arterial coagulation group. Furthermore, the three failures were successfully treated with anterior ethmoidal arterial coagulation. The conclusion is that combined internal maxillary and anterior ethmoidal arterial occlusion is the treatment of choice in intractable epistaxis.
Audiological, vestibular and radiological abnormalities in Kallman's syndrome
Authors: Hill J. , Elliott C. , Colquhoun I. 
Published: November 2007

AbstractKallman's syndrome is a multifaceted congenital disorder with predominantly endocrine abnormalities. We have characterized the associated mixed hearing loss and identified consistent radiological evidence of abnormal temporal bone anatomy. Abnormal labyrinthine morphology is accompanied by a complete absence of response to vestibular stimulation with caloric or rotational chair testing.The endocrine abnormalities are correctable and Kallman's syndrome is a diagnosis worthy of consideration when assessing children with congenital hearing loss.
Granulomatous cutaneous T-cell lymphoma of the neck

Published: November 2007

AbstractA case of cutaneous T-cell lymphoma is presented in which the diagnosis was obscured by a concomitant granulomatous infiltrate. A working diagnosis of tuberculosis delayed appropriate treatment for several months over which time rapid progression of the disease was seen. Inclusion of overlying skin in the repeat biopsies yielded the histological information to establish the correct diagnosis and there was rapid regression on completion of a course of radiotherapy.
Experimental studies on the acoustic properties of mastoid cavities
Authors: Tolley N. S. , Ison K. , Mirza A. 
Published: November 2007

AbstractThis study investigated the effects of open-mastoid surgery upon ear canal resonance. In particular an attempt was made to alter resonant properties by obliterating each cavity with silastic foam. The results from this study showed that open-mastoid surgery significantly decreased resonant frequency without producing an effect upon either the peak amplitude or the quality of the resonant peak as defined by the Q-factor.Restoring the natural resonance properties of an operated ear, if indicated, is likely to be a difficult objective to achieve in surgical terms.
Treatment of tinnitus by intratympanic instillation of lignocaine (lidocaine) 2 per cent through ventilation tubes
Authors: Podoshin Ludwig , Fradis Milo , David Yacov Ben 
Published: November 2007

AbstractIdiopathic subjective tinnitus (1ST) is one of the most obscure otological pathologies. This paper presents the results of treating 1ST by intratympanic instillation of lignocaine (lidocaine) 2 per cent through a grommet, for five weekly courses. Fifty-two patients suffering from intractable tinnitus entered this therapeutic trial, but only nine finished all five courses. In one patient, the tinnitus was almost completely abolished, but in all the nine patients the decompensated tinnitus changed to a compensated one. We suggest this mode of treatment for patients that were previously treated by drugs, acupuncture and biofeedback, with disappointing results.Patients should be warned about the side effects of vertigo and vomiting, which subsides gradually with every new instillation, and that the tinnitus may not disappear but will be alleviated, enabling them to cope more easily with the disease and lead a more normal life.

Authors: Kimura Yasuyuki , Miwa Takaki , Furukawa Mituru 
Published: November 2007

AbstractCowden's disease is characterized by multiple hamartomas and neoplasias of ectodermal, mesodermal and endodermal origin. A case of a 22-year-old man suffering from nocturnal dyspnoea is reported. The patient had a large number of hyperkeratotic, lichenoid papules, scattered over the right side of the trunk, back and palm. In his oral cavity, papules were present on the gingiva and hard palate. The patient was operated on for tonsillar hypertrophy and for excluding the possibility of malignant lymphoma. An examination of immunophenotypes of the palatal tonsil lymphocytes revealed B-cell proliferation and poly-clonal immunoglobulin.
Long-term results of total ossicular chain reconstruction using autografts

Published: November 2007

AbstractThe long-term results of 63 total ossicular chain reconstructions using autografts is presented. The follow-up period ranged from 18 months to 18 years with an average of 8.5 years. The primary aims of the study were firstly to assess the long-term success rate and to find out if there were any hitherto unknown causes of bone graft failure. In the event, it was found that the recently described anatomical variation of the oval windowviz., the deep oval window, was the prime cause of failure in 32 per cent of unsuccessful cases. Some measures to help to mitigate this problem, are suggested. The result were assessed on the basis of:1. A minimum gain of 20 dB HL in air conduction (Technical success). The success rate was 55.5 per cent.2. Patients benefited using Smyth and Patterson's criteria in conjunction with the Glasgow Benefit Plot; 54 percent of the patients benefited significantly.
Ossiculoplasty with the use of autografts and synthetic prosthetic materials: A comparison ofresults in 165 cases

Published: November 2007

AbstractOne hundred and sixty-five cases of different kind of ossiculoplasty in patients suffering from chronic middle ear disease were performed at the ENT department of Papanikolaou Hospital in Thessaloniki, Greece, during the years 1988–1990. There were 40 cases of incus transposition, 47 cases in which polyethylene TORPs and PORPs were used and 77 cases of hydroxylapatite prostheses (41 TORPs and 37 double notch PORPs). Hearing success was defined as a post-operative air-bone gap of <20dB. According to this criterion 74 percent of the incus transposition cases were successful, 61 percent of the polyethylene TORPs, 65 percent of the hydroxylapatite TORPs, 40 percent of the polyethylene TORPs, and 89 percent of the double notch hydroxylpatite PORPs. It is obvious that ceramic PORPs produced the best results, while there was no statistical difference, regarding the hearing improvement, among the different kinds of TORPs which were used. Extrusion rate and other kinds of complications are also discussed, as well as a case of severely damaged ceramic TORP, within two years due to middle ear infection.
Radiological and endoscopic study of the maxillary sinus in primary atrophic rhinitis

Published: November 2007

AbstractThe maxillary sinuses of 40 patients suffering from primary atrophic rhinitis (ozaena) were studied radiologically, antroscopically and histopathologically. Sixty percent of the patients showed thick bony walls and a small cavity of the maxillary sinus on X-ray and on antroscopy. On the other hand, 25 percent of the cases revealed signs of infection including mucopurulent secretion on antroscopy associated with corresponding histopathological changes. It is concluded that poor pneumatization of the antrum plays a more important role in the pathogenesis of ozaena than infection.

Published: November 2007

AbstractForeign body aspiration is a very common problem in children and toddlers and still a serious and sometimes fatal condition. We are reporting on a 2-year-old white asthmatic male who choked on a chick pea and presented with subcutaneous emphysema, and on chest X-ray with an isolated pneumomediastinum but not pneumothorax. On review of the literature an isolated pneumomediastinum without pneumothorax was rarely reported. This presented a challenge in management mainly because of the technique that we had to use in order to undergo bronchoscopy and removal of the foreign body. Apnoeic diffusion oxygenation was used initially while the foreign body was removed piecemeal, and afterwards intermittent positive pressure ventilation was used. The child did very well, and his subcutaneous emphysema and pneumomediastinum remarkably improved immediately post surgery.

AbstractA 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.
Perforating injury of the neck and vertebral artery trauma
Authors: Farrell M. L. , Gray R. F. 
Published: November 2007

AbstractA 10-year-old schoolboy presented with a penetrating wound to the neck after a children's slide accident. A CT scan and endoscopy showed a traumatic oesophageal-cutaneous fistula. Neurologically the child deteriorated over a period of 34 hours and finally succumbed to a respiratory arrest.Post-mortem findings showed a hypoplastic right vertebral artery. In the left suboccipital triangle a venous clot had blocked the dominant artery thus leading to cerebellar and brainstem infarction.This extraluminal compression leading to obstruction of an otherwise non traumatized vertebral artery is unique in the literature.
