Routine radiological examination of the sinuses before septoplasty
Authors: Jensen Jørgen Hedegaard , Dommerby Hans 
Published: November 2007

AbstractRecords of septoplasties performed during the last five years were reviewed with the aim of evaluating the results of routine pre-operative radiological examination of the sinuses. A positive correlation was found between the information of sinusitis within the last two years and the radiological finding of complete density or fluid. The roentgenograms showed normal conditions in 73 per cent of the cases and various degrees of pathology in 27 per cent; no case showed signs of malignancy. Puncture and irrigation or sinoscopy had been performed in 52 per cent of the cases with pathological X-rays. Following this treatment, surgery was postponed in 12 patients, and in nine patients a drainage tube was placed in the maxillary sinus per-operatively. Complications developed post-operatively in five of these nine patients and it is concluded that septoplasty should have been postponed. We find that it is important to identify the four per cent (12+9) of patients in whom the radiological findings are so pronounced that operation ought to be postponed.
Auditory brainstem evoked potentials in asymptomatic lead-exposed subjects
Authors: Holdstein Y. , Pratt H. , Goldsher M. , Rosen G. , Shenhav R. , Linn S. , Mor A. , Barkai A. 
Published: November 2007

AbstractAuditory Brainstem Evoked Potentials (ABEP) were recorded from 29 adults and children, accidentally exposed to lead through food until approximately a year prior to this study. ABEP were recorded in response to 75 dBHL click presented at rates of 10/sec. and 55/sec. Average values were calculated for peak latency and for interpeak latency differences. Average values of the effect of increasing stimulus rate were calculated as well. Similar values were calculated for normative child and adult control groups.IPLD (I-III) showed the most significant and recurring results, with longer intervals in lead-exposed children compared with their control group. Increasing stimulus rate, on the other hand, affected the adult lead-exposed subjects more than the children. These results may imply an impairment of the auditory system with azonal and myelin involvement. ABEP is suggested as a sensitive detector of subclinical lead exposure effects on the nervous system.
Revision tympanoplasty
Authors: Tos Mirko , Lau Torben 
Published: November 2007

SummaryThe terms ‘planned two-stage operations’, ‘planned second-look operations’, ‘previous surgery’, and ‘revision surgery’ are discussed on the basis of our series of 2,303 ears operated upon from January 1965 to December 1980. We have not performed any planned two-stage operations. All operations prior to the first operation in our department are denoted ‘previous surgery’. ‘Revision surgery’ denotes all reoperations performed either in this department or elsewhere during the observation period until the end of 1984, and the revision rate is analysed in patients with different pathological conditions. ‘Revision surgery’ was performed in 15.6 percent of 740 ears with cholesteatoma (in 13.9 percent once, in 1.6 percent twice, and in 0.1 percent three times), and ‘previous surgery’ in 3 percent.Among 229 ears with chronic granulating otitis, revision surgery had been performed in 12.2 percent up to December 1982. By December 1984, this figure had risen to 16.1 percent. ‘Previous surgery’ had been performed in 18.3 percent. A total of 38.4 percent had at least two operations.The revision rate in other conditions varied from 10 percent (sequelae to chronic otitis) to 34 percent (post-inflammatory acquired atresia). These rates are discussed and the functional results presented.
Surgical management of labyrinthine fistula with cholesteatoma
Authors: Gormley Peter K. 
Published: November 2007

SummaryFrom 684 cases of ear surgery for cholesteatoma performed by one surgeon, 35 had labyrinthine fistulae (incidence 5.1 per cent). Of these fistulae, 79 percent involved the lateral semicircular canal only; the other sites involved were the other semicircular canals and the cochlea. The fistula test was positive in 54 per cent of cases overall, but in 80 per cent with an extended site fistula (ESF). Three surgical approaches were employed sequentially—staged combined approach tympanoplasty (CAT), open cavity tympanoplasty and attico-antrotomy. Surgically-induced deafness occurred in 3.3 per cent. All surgical groups showed similar hearing results, except for less conductive deafness in the CAT group. Surgical management is discussed with reference to current theories of the erosive effects of cholesteatoma.
Bronchial changes in airborne tularemia
Authors: Syrjälä Hannu , Sutinen Seppo , Jokinen Kalevi , Nieminen Pentti , Tuuponen Tuula , Salminen Aimo 
Published: November 2007

AbstractWe describe seven typhoidal tularemia patients without ulcers or lymphadenopa-thy, who underwent diagnostic bronchoscopy. Four patients had had obvious airborne exposure toF. tularensisduring farming activities, and the remaining three had respiratory symptoms also. Bronchoscopical findings were pathological in all cases, varying from local to diffuse haemorrhagic inflammation; in one case a granulomatous tumour was seen. Early histopathological changes in three biopsies consisted of haemorrhagic oedema progressing to a non-specific inflammatory reaction, which could still be found 45 days after the onset of symptoms. Granulomatous inflammation, indistinguishable from tuberculosis or sarcoidosis, was seen in four biopsies from two patients, three to seven months after the onset. Most patients had radiographic hilar enlargement. We conclude that transmission of typhoid tularemia usually occurs through inhalation leading to bronchial changes, which correspond skin ulcerations in ulcero-glandular tularemia, the hilar enlargement corresponding to the lymph node component. We emphasize that usage of the term ‘typhoidal’ tularemia should be discontinued. Instead, tularemia transmitted through inhalation should be called pulmonary or respiratory.
Vestibular effects of intravenous lidocaine used in the treatment of tinnitus
Authors: Merchant Saumil N. , Kirtane Milind V. 
Published: November 2007

AbstractIntravenous lidocaine is known to have an effect on the auditory system in that it is useful for suppressing tinnitus, albeit temporarily. We have used intravenously administered lidocaine as one of the treatment modalities for refractory, disturbing, tinnitus. Its effects on the vestibulo-ocular system were determined by elec-tronystagmography performed before and immediately after injecting lidocaine: smooth pendular stimulus tracking was unaffected; spontaneous and positional nystagmus tended to be suppressed; directional preponderance was reduced or reversed; and the difference between the nystagmus responses in the two directions during the pendular rotation chair test was also reduced or reversed. These changes in the caloric and rotation tests were statistically significant. Lidocaine also appeared to have altered the balance between the two sides in the vestibulo-spinal system as indicated by the results of the stepping test during craniocorpography. The results lend support to the hypothesis that intravenous lidocaine acts at the level of the central nervous system rather than at the periphery.
Early morphological and chemical changes induced by cisplatin in the guinea pig organ of Corti
Authors: Comis Spiro D. , Rhys-Evans Peter H. , Osborne Michel P. , Pickles James O. , Jeffries David J. R. , Pearse Henry A. C. 
Published: November 2007

AbstractGuinea pigs were treated with a single dose of Cisplatin (5 mg IP). After 2–4 days the cochleas were prepared for morphological analysis by scanning electron microscopy and chemical analysis by X-ray dispersive microanalysis. Following Cisplatin, the bundles of stereocilia on the hair cells were found to be rough, disarrayed, fused, and finally absorbed. Significant increases were found in the levels of calcium, sulphur, and phosporus in the abnormal hair cells. It is suggested that the high calcium levels might be due to the inhibition of enzymes which normally keep cytoplasmic calcium low, and that some of the changes in the stereocilia might be secondary to this.
Malignant external otitis versus acute external otitis
Authors: Cohen David , Friedman Peter , Eilon Amos 
Published: November 2007

AbstractMalignant External Otitis (MEO) and Acute External Otitis (AEO) are clinically very similar in their beginnings. It is important to differentiate between them very early. Bone scanning is the best diagnostic tool. Eight cases of AEO and MEO are herewith presented.
A technique of tongue reconstruction following near-total glossectomy
Authors: Robertson Malcolm S. , Robinson Jeffrey M. , Horsfall Ruth M. 
Published: November 2007

AbstractTotal glossectomy is the most crippling of all oral cavity resections. Speech problems are unavoidable and post-operative aspiration is often severe. Two patients are presented who have had tongue reconstructions following near-total glossectomies. In each case a quilted, split-skin grafted pectoralis major muscle flap was used. The speech and swallowing results of these two patients are compared with two patients who underwent a hemiglossectomy and total glossectomy respectively without tongue reconstruction. Only if the suprahyoid and extrinsic tongue muscles are preserved can an active oral phase of swallowing and usable speech be regained by tongue reconstruction.
Is otosclerosis a generalized connective tissue disorder?
Authors: Oxlund H. , Pedersen U. , Danielsen C. C. , Oxlund I. , Elbrønd O. 
Published: November 2007

AbstractIt has been suggested that otosclerosis might be caused by a generalized disorder in the connective tissue.The biophysical and biochemical properties of skin biopsies from twelve patients with otosclerosis and twelve age- and sex-matched controls were investigated. No differences were found in skin strength and extensibility, skin thickness, collagen content, the relationship between collagen type I and type III, reducible collagen cross-links and molecular stability of collagen type I of samples from patients with otosclerosis as compared with those from the controls. The present study does not support the suggestion that otosclerosis might be a generalized connective tissue disorder.
Submucous diathermy of the inferior turbinates in chronic hypertrophic rhinitis
Authors: Talaat Mamdouh , El-Sabawy Eshrak , Baky Fathy Abdel , Raheem Ahmed Abdel 
Published: November 2007

SummaryTwenty patients, 10 allergic and 10 non-allergic, with chronic hypertrophic rhinitis and presenting mainly with bilateral nasal obstruction were subjected to sub-mucosal diathermy of their inferior turbinates. There was significant post-operative improvement clinically, histopathologically and histochemically in the non-allergic group, while the improvement was less obvious in the allergic cases. The post-operative clinical improvement as regards rhinorrhea and sneezing was not as marked as that for nasal obstruction. Evaluation of the results showed that sub-mucous diathermy of inferior turbinates is a good line of treatment for cases of chronic hypertrophic rhinitis, with better results in the non-allergic group of patients.
Hearing loss in a uraemic patient: indications of involvement of the VIIIth nerve
Authors: Lucien J. C. Anteunis , Mooy M. V. Mooy 
Published: November 2007

A case of acute renal failure associated with severe uraemic hearing loss is presented. Audiometric site-of-lesion testing revealed cochlear as well as neural involvement.After therapy hearing recovered up to an almost normal level, with normal auditory nerve conduction velocities.This case report supports the suggestion that the improvement of hearing after renal transplantation or dialysis might be correlated with the influences of these forms of therapy upon the peripheral neuropathy.
Tonsillar leiomyoma
Authors: Greenberg E. , Shupak A. , Kelner Judith , Meyer W. S. 
Published: November 2007

AbstractTumors of smooth muscle origin are rare in the oral cavity. To date, only eighty-three cases of oral leiomyomas have been reported. A first case of tonsillar leiomyoma in a 73-year-old male is presented. The theories of origin and the various histologic types of oral leiomyomas are discussed. Leiomyoma can easily be confused with other spindle-cell tumours. Special stains are necessary to reach a correct diagnosis. It is sometimes difficult to differentiate benign leiomyoma from malignant leiomyosarcoma. The use of mitotic figure count to indicate malignant behaviour is not always reliable. The need for wide surgical excision of the tumour, complete sectioning and examination of the specimen and meticulous follow-up of the patient for evidence of recurrence are emphasized.

Authors: Fradis M. , Podoshin L. , Gertner R. 
Published: November 2007

SummaryThe object of this double-blind study was to assess the therapeutic effects of a combination of two per cent sodium cromoglycate and 0.025 per cent xylometazoline compared with a matched placebo. Forty patients were included in the two-week study.The treatment was found to be rapidly effective taking only a day to control symptoms in almost 80 per cent of the patients in the group receiving active treatment.No evidence of rebound effects due to the decongestant was observed during the study.
Hyponatraemia and hypothyroidism in a previously irradiated case of carcinoma of the tongue
Authors: Nasser N. A. , Lever E. G. 
Published: November 2007

AbstractA case of squamous cell carcinoma of the tongue was complicated by post operative hyponatraemia. The criteria for the syndrome of inappropriate secretion of anti diuretic hormone, [ADH] (SIADH) were met but the patient remained hyponatraemic despite adequate treatment. The patient had previously received radical external radiotherapy to the neck and was found to be profoundly hypothyroid. Correction of the hypothyroid state led to clinical and biochemical recovery. The frequency of post-irradiation hypothyroidism and the possible mechanisms of hypothyroid-induced hyponatraemia are discussed

Published: November 2007

A laryngocele is an air-filled dilatation of the saccule of the larynx. An in fected laryngocele is called a laryngopyocele. Our experience with two cases of laryngopyoceles are presented. Only 29 cases of laryngopyoceles have so far been reported in the literature (Illum and Nehen, 1980).Case one had a right-sided combined laryngopyocele and case two had a right-sided combined laryngopyocele and a left-sided combined laryngocele.Both our cases had their lesions excisedviaan external approach, as described by Yarington and Frazer (1966), with case two having a bilateral excision.
Phase variation in nasal airways resistance assessed by active anterior rhinomanometry
Authors: Kenyon G. S. 
Published: November 2007

AbstractMeasurements of nasal airways resistance in normal subjects have shown a significant difference between values obtained in the two respiratory phases. Higher overall values are found during expiration in both the unprepared and decongested nose but these differences fail to maintain statistical significance after application of a decongestant. This indicates that the phase of respiration in which measurement is made must be routinely recorded especially when measurement is made without decongestant, and comparisons of data made only with recordings from equivalent parts of the nasal cycle.
Aetiology of recurrent aphthous ulcers (RAU)
Authors: Maurice Monir , Mikhail Wadie , Aziz Medhat , Barsoum Maged 
Published: November 2007

AbstractA significant decrease in the pH of saliva has been detected in patients with recurrent aphthous ulcers (RAU). The decreae in pH was more prominent at night than between meals, and some persistent decrease was noticed even after recovery. The total proteins of saliva in RAU were also significantly decreased.These findings were similar to those observed in patients complaining of petic ulcers, so it is recommended that patients with RAU should be treated with antacids as well as anticholinergic drugs, and that the possibility of concomitant peptic ulceration should also be investigated.

Published: November 2007

AbstractA case of trigemino-facial zoster presenting as Superior Orbital Fissure Syndrome is reported. Geniculate ganglion involvement was limited to the vestibular branch of the cochleo-vestibular nerve, without any hearing impairment of facial palsy. this case clearly illustrates that herpes zoster cranialis is a polyneuropathy of multifocal asynchronous viral activity and can present in numerous forms.
Intratympanic ototoxicity: influence of post-injection survival period
Authors: Yung M. W. 
Published: November 2007

AbstractMany studies have been reported on the intratympanic ototoxicity of different drugs in animal models. The recovery periods of the animals following intratympanic drug applications varied among these studies. The present study compares the cochlear damage caused by intratympanic kanamycin following short (4 days) and long (30 days) post-injection survival periods, using the guinea pig as the animal model.The degree of cochlear damage 4 days after kanamycin injection was consistent among the tested animals. The degeneration was mainly confined to the outer hair cells and almost all inner hair were spared. The change 30 days after kanamycin injection was more variable among the animals and both inner and outer hair cells were damaged. This shows that, although the damage to the cochlea after intratympanic aminoglycoside injection is progressive, a short post-injection recovery period is suitable for comparative intratympanic ototoxicity studies.

Published: November 2007

AbstractOver the 27-year period from 1954–1981, 51 patients with non-Hodgkin's lymphoma arising in the tonsil were treated at the Regional Radiotherapy Centre, Mount Vernon Hospital. The original biopsy material was reviewed in each case and reclassified using the British National Lymphoma Investigation criteria. Grade 2 non-Hodgkin's lymphoma was reported in 80 per cent of cases. Ninety per cent of patients presented in stages IE or HE and were treated with radical local radiotherapy. A 5-year survival of 51 per cent was achieved and a 5-year relapse-free survival of 35 per cent. Stage IE patients had a statistically significant survival advantage compared to stage HE. Sixty-one per cent of patients relapsed, of whom 74 per cent died from active lymphoma. The abdomen was the most frequent site for relapse with involvement of both nodal and extranodal sites.
Laryngeal trauma vs length of intubation
Authors: Lesser T. H. J. , Lesser P. J. A 
Published: November 2007

SummaryThe frequency histograms of six patients' laryngographs were studied pre- and post-endotracheal intubation. The changes were correlated with the length of intubation. The post-operative hoarse voice was seen as an increase in the spread of the lower frequencies, and an increase in the fundamental frequency. The latter change was thought to be a subconscious compensation for the hoarseness. The increased lower frequency spread as measured by standard deviation was directly proportional to the length of intubation.

A short review of some earlier reports on congenital hearing loss in this syndrome is made.
Mucoepidermoid carcinoma in a minor salivary gland in childhood
Authors: Gustafsson Hans , Dahlqvist Åke , Anniko Matti , Carlsöö Bengt 
Published: November 2007

SummarySalivary gland neoplasms in childhood and adolescence are rare, especially in the minor salivary glands. Vasoformative tumours and pleomorphic adenomas appear to be the most common benign neoplastic salivary gland lesions in the pediatric age group. The distribution of various malignant histological types is not always consistent with that in the adult population, and they appear more often in girls than in boys. Only 17 cases have previously been documented. The clinical and histological picture of a case of palatal mucoepidermoid carcinoma in a 13-year-old girl is presented as well as a review of the literature on malignant salivary gland tumours in childhood.

The branchio-oto-renal syndrome
Authors: Raspino M. , Tarantino V. , Moni L. , Verrina E. , Ciardi M. R. , Gusmano R. 
Published: November 2007

SummaryThe major features of the Branchio-Oto-Renal syndrome (BOR syndrome), an autosomal dominant disorder, are branchial remnants, ear anomalies, deafness and renal dysplasia.We report two family groups affected by the BOR syndrome: in two-thirds of the affected children renal abnormalities led to severe renal insufficiency in early life. The necessity for a meticulous search for renal anomalies in individuals with aural and/or branchial abnormalities is emphasized. In affected families, genetic counselling is suggested.
Budesonide nasal spray as prophylactic treatment after polypectomy

Published: November 2007

SummaryThis double-blind parallel-group study compared the effect of budesonide with placebo, in the prophylaxis of nasal polyp recurrence after evulsion. Seventy-three patients with first time or recurrent polypectomy were enrolled. At revisits 3 and 6 months after evulsion, the budesonide-treated patients had significantly lower polyp scores than the placebo-treated patients. Only patients with recurrent nasal polyposis benefited from the budesonide treatment, whereas no effect was evident in patients with first time evulsion

SummaryThis study was undertaken to determine the incidence of unidagnosed apical disease in acute unilateral sinusitis and to evaluate the role of Orthopantomograms (OPGs).Our results, with an incidence of 10 per cent, are in agreement with the findings of Formby (1960) and we conclude that OPGs are not justified in the routine investigation of acute sinusities.
