Progressive hemifacial atrophy (Parry-Romberg's disease), principally involving bone
Authors: Goldhammer Yochanan , Kronenberg Jona , Tadmor Rina , Braham Jackson , Leventon George 
Published: November 2007

AbstractA case of progressive hemifacial atrophy (PHA) with extensive atrophy of the walls of the maxillary sinus is reported. Prolapse of subcutaneous tissue and orbital fat through the bony defect simulated the presence of a tumour and led to surgical exploration. Such a severe degree of bony involvement with relatively mild soft tissue atrophy is exceptional. Radiological evaluation by hypocycloidal tomography contributed greatly to the diagnosis in this case.Unilateral progressive atrophy of the face was first described by Parry (1825) and by Romberg (1846). Eulenberg (1871) coined the name ‘progressive facial hemiatrophy’, but ‘progressive hemifacial atrophy’ (PHA) is a more appropriate term (Gorlin and Pindborg, 1964; Kabir and Halprin, 1964). The disease commences usually in the first or second decade of life, and is more common in females. Over several years there is a slowly progressive atrophy of the face on one side, with involvement of the skin and subcutaneous fat, and on rare occasions also of the muscles and bones (Gorlin and Pindborg, 1964; Finesilver and Rosow, 1938; Bramley and Forbes, 1960; Singh and Bajpai, 1969; Crikelair et al., 1962). The etiology of the disease is unknown.We report an unusual case in which the hemifacial atrophy affected the bone much more than the soft tissues and which presented as a mass in the maxillary sinus.
Hidradenoma papilliferum of the external auditory canal
Authors: Nissim Florence , Czernobilsky B. , Ostfeld E. 
Published: November 2007

AbstractThis is a report of a 32-year-old woman who presented with a hidradenoma papilliferum of the external auditory canal. The lesion bears a marked histologic resemblance to vulvar hidradenoma papilliferum and to intraductal papillioma of the breast and, as in the latter neoplasm it may malignancy. However, these are benign tumours and warrant only local resection. Clinical symptoms related to obstructure of the external ear and some hearing loss.This report emphasizes again the variety of neoplasms which occur under the generic name of ceruminoma. It is recommended that each of these tumours be classified according to its characteristic histologic features and that the term ceruminoma, as used at present, be abandoned.Adenomas of the ceruminous glands located in the external auditory canal are rare tumours (Batsakis et al., 1967; Cankar and Crowley, 1964; Pluec, 1977). About forty cases have so far been reported in the literature (Dehner and Chen, 1980). The histological classification of these benign ceruminous tumours is similar to that used for sweat gland tumours in other locations (Neldner, 1968; Pahor and O'Hara, 1975; Wetli et al., 1978).The most common type demonstrates features of glandular or tubular adenoma with epithelial structures which are similar to those of normal apocrine glands (Althaus and Ross, 1970; Anagnostou et al., 1974; Leitner, 1952; Camkar and Crowley, 1964). The second type of benign ceruminoma is the pleomorphic adenoma (Mark and Rothberg, 1951; Smith and Duarte, 1962; Pahor and O'Hara, 1975). Its histogenesis from ceruminous or ectopic salivary glands is still debated.The purpose of this paper is to report still another type of benign ceruminoma, namely the hidradenoma papilliferum which so far has only been mentioned as a theoretical possibility (Dehner and Chen, 1980).
Late post-operative hearing results correlated with the severity of tissue changes in ears with chronic otitis media
Authors: Ojala Kauko , Sorri Martti 
Published: November 2007

AbstractLate hearing results in 627 ears (574 patients) operated on radically for chronic otitis media are presented. Clinically, the ears were followed-up annually for 5–14 years. The results are correlated with the severity of histopathological changes in the tympanic cavity and in the mastoid air-cell system and also with the management of the tympanic mucosa and ossicular chain at operation.The mean post-operative air-bone gap was significatly better in ears with mild histopathological changes than in ears with sever histopathological changes in the middle ear (17.0 db./33.1 db.; p<0.001) or mastoid (29.0 db./34.2 db.; p<0.01) at operation. The difference in hearing results in favour of the former group was more significant in ears in which the tympanic mucosa had been saved at operation (p<0.01/p<0.001) than in ears in which the mucosa had been removed (p<0.05).
Long-term results of dermatoplasty in the treatment of hereditary haemorrhagic telangiectasia
Authors: Ulsø C. , Vase P. , Stoksted P. 
Published: November 2007

SummaryDematoplasty for the treatment of epistaxis caused by HHT has become well established. A modification of Saunders's (1960) original dermatoplastic technique is described, which permits the nasolabial incision to be avoided.This retrospective study of the long-term effect on epistaxis caused by HHT demonstrates, in contrast to those with a short period of observation, that epistaxis can be partially controlled by means of dermatoplasty and, further, that it is impossible to eliminate completely the need for blood transfusion.In two of the patients it was found that newly formed telangiectases had occurred in the transplant 15 and 18 years post-operatively.
Laryngeal tuberculosis in Tanzania
Authors: Manni Hans 
Published: November 2007

AbstractThe incidence of laryngeal tuberculosis in 341 patients with pulmonary tuberculosis was assessed in Dar es Salaam, Tanzania. Laryngeal involvement was present in 26.7 per cent of previously untreated cases. The clinical presentation corresponds to classical descriptions of the disease found in previous accounts. It is suggested that laryngeal tuberculosis is a common complication of pulmonary tuberculosis in developing countries. It should be the first differential diagnostic consideration in patients suffering from hoarseness, and pulmonary tuberculosis should be ruled out before a diagnostic direct laryngoscopy and biopsy are attempted.
Otomycosis—A continuing problem
Authors: Mugliston T. , O'Donoghue G. 
Published: November 2007

AbstractThe microbiology of 12, 174 symptomatic ears presenting over an eingt-year period to one hospital was examined in detail. 1, 061 cases of fungal infection were found. The incidence and pattern of these fungi and the accompanying bacteria, in case of mixed infection, do not appear to have been affected by the widespread use of powerful topically-applied autibiotic/steroid preparations over more than two decades. Otomycosis remains an uncommon, often overlooked but important cause of morbidity in a temperate climate.
Experimental investigation of temperature gradients in the inner ear following Argon laser exposure
Authors: Ricci T. , Mazzoni M. 
Published: November 2007

Abstract In microsurgery of the middle ear using argon laser, heat is produced on the sensorineural structures adjacent to the irradiated bones.Thermal gradients following laser applications have been measured by means of special thermocouples.The footplate was perforated by a 50 msec. ray applied both at 380 m Watt and at 460 m Watt. The maximum temperature increase registered in the labyrinthine spaces was respectively 2oc. and 3.5oC.Coagulation of the promontory mucosa was performed using 100 msec. impulses at 200 m Watt. At the end of a series of 12 applications the temperature increase at the level of the basal coil was 1.4oc.From the above results the authors conclude the no damage is induced during laser microsurgery and that, considering the power and time values relative to impulses, the use of laser in routine clinical practice should be relatively safe.

Published: November 2007

AbstractWe have studied 47 children (58 ears) with external and middle-ear malformations. Tomography was useful and effective in the pre-operative evaluation of anatomical patterns. We have divided our cases into four groups and described the most characteristic tomographic findings in each. We also discuss problems concerning patients immobilization and X-ray protection.

Published: November 2007

Abstract Eighty-eight patients from 16 to 79 years old, with acute purulent otitis media, were bacteriologically examined at the Otorhinolaryngology Department of a primary care hospital in Tokyo from July 1979 to May 1983. Fifty-six patients underwent paracentesis, and 32 patients exhibited otorrhea due to previous spontaneous perforation of the tympanic membrane.Bacteriologic cultures revealed the presence ofStreptococcus pneumoniae(62.5 per cent), includingS. pneumoniae Type III(28.1 per cent),Haemophilus influenzae(10.5 per cent),Staphylococcus aureus(11.5 per cent), andStreptococcus pyogenes(7.3 per cent).S. pneumoniae Type IIIhad a notably high detection rate in patients from 50 to 79 years old (50–75 per cent). BecauseHaemophilus influenzaewas detected at a relatively high rate in patients of all ages, if can be considered as a was detected at a relatively high rate in patients of all ages, if can be considered as a major causative pathogen of AOM.In 44 patients, selected mainly from those who underwent paracentesis, a comparative study of bacteria found in middle ear fluid and naso-pharyngeal mucus revealed the same nacteria in 43 out of 44 cases. (97.7 per cent), indicating the presence of bacterial infection through the auditory canal.Antibiotics were selected according to an Expected Efficiacy Index (EEI), the antibiotic of first choice being Ampicillin or Cefaclor.
A comparison of the effects of eighth nerve section with lidocaine on tinnitus
Authors: Jackson P. 
Published: November 2007

AbstractThe success rate of eighth nerve section in abolishing tinnitus is disappointing and the results generally unpredictable. A comparison of the effects of a bolus intravenous injection of lidocaine with the effects of nerve section is reported: it presents some evidence that the response to lidocaine may be of value in selecting patients for nerve section, and further it may shed some light on the site of action of lidocaine in suppressing tinnitus.
Electrocochleographic findings and the effects of lidocaine on tinnitus in non-hearing ears.
Authors: Jackson P. 
Published: November 2007

AbstractIn the preceeding report (Jackson, 1985) the author produced evidence which brought into question the widely held view that, in abolishing tinnitus, lidocaine was acting ‘centrally’. This present investigation is another approach to attempt to narrow the site of action of lidocaine in abolishing tinnitus.During a four-year period, patients suffering from strictly unilateral tinnitus which was referred to, and therefore apparently arising from, an ipsilateral ‘dead’ ear, underwent electrocochleography. Additionally, the subjective effect on the tinnitus of a bolus injection of lidocaine was recorded. Nine patients were available for this study, which appears to show a correlation of the results of the elec-trocochleogram and the effects of the lidocaine injection, although the numbers are small.
Brain stem auditory evoked potentials and blink reflexes in multiple sclerosis
Authors: Ferguson I. T. , Ramsden R. T. , Lythgoe M. 
Published: November 2007

SummaryBrain stem auditory evoked potentials (BAEP) and the blink reflex (BR) were recorded from 50 patients with a wide spectrum of multiple sclerosis, to determine whether the combination of the two tests of brain stem function would yield a higher rate of abnormality than each test performed alone. Sixty-four per cent of patients had a BAEP abnormality and fifty-two per cent had an abnormal BR, but when the results were combined, seventy-six per cent were abnormal. The blink reflex was abnormal in all patients with symptoms suggestive of trigemino-facial pathology.
The role of fibreoptic nasopharyngoscopy in nasopharyngeal carcinoma (NPC)
Authors: Shanmugham M. S. 
Published: November 2007

AbstractWith the introduction of the flexible fibreoptic nasopharyngo-laryngoscope, we have a sophisticated instrument for examination of the nasopharynx and larynx. It is also useful for obtaining biopsies from the nasopharynx and has many advantages over other methods. The most important is that it is possible to take biopsies from selected sites under direct visualization and the biopsy results are therefore more reliable.
Relationships between acoustic reflex patterns elicited by unfiltered white noise and narrow band white noise stimuli of different duration but of the same intensity
Authors: Rossi Giovanni , Solero Paolo , Rolando M. 
Published: November 2007

AbstractFor the purpose of this study, acoustic signals were generated by an Amplaid MK VI. An Amplaid 702 impedence meter was connected to its averaging section and to its computer. The stimuli were bursts of unfiltered white noise (UWN) and of narrow band white noise (NBWN; 30 db./oct/slope; central frequencies 1,000, 2,000, 4,000 Hz.) lasting 3–1,000 msec, at intensity of 105 db. SPL p.e. The following parameters were evaluated: stapedius contraction latency, amplitude, duration and recruitment time. It was found that latency was independent of the spectrum of the stimulus and its duration. Amplitude and recruitment time, on the other hand, were related to spectrum and duration, while duration of contraction was directly related to the duration of the stimulus only.
Squamous odontogenic tumour: Review of the literature and a new case
Authors: Kristensen S. , Andersen J. , Jacobsen P. 
Published: November 2007

AbstractSquamous odontogenic tumour (SOT) is a rare benign odontogenic neoplasm, apparently arising from rests of Malassez. It was first described in 1975 and since then only 17 cases have been recorded in the literature.A new, not previously reported, characteristic case of SOT is presented in connection with a review of the literature.It is concluded that the lesion occurs with equal frequency in the maxilla and mandible and now and then multifocally. Maxillary lesions seem to grow more aggressively than do mandibular ones. The symptoms are modest.SOT has a characteristic pathologic picture which differs decisively from ameloblastoma and which, in connection with its benign nature, warrants the classification of SOT. Although most cases have been treated by conservative surgical therapy without recurrence, there are cases, especially in the maxilla with diffuse lesions, which have required en bloc resection or hemimaxillectomy.The diagnostic problems are stressed and recommendations are made for the pathologist and the surgeon to pay attention to this rare but benign tumour.
Aural tuberculosis: a series of 25 patients
Authors: Ramages L. J. , Gertler R. 
Published: November 2007

AbstractTwenty-five patients with thirty ears affected by tuberculosis of the middle ear cleft were diagnosed and treated at Groote Schuur Hospital, Cape Town, during the years 1972 to 1983. This series is a sequel to the series of 1967 to 1971 and reported by Sellars and Seid (1973). The classical disease presentation will be reviewed and compared to that found in our patients. The modern trends in diagnosis and management will be discussed. The emphasis is on early diagnosis and treatment in an eminently curable disease.
Scanning electronic mircroscopy of sialit-preserved total middle-ear grafts
Authors: Zeneva I. , Betow C.H. 
Published: November 2007

SummaryTwelve middle ears from human cadavers, prepared for total grafting and preserved in sialit (1:5000) for more than 10–12 months, were studied with the aid of a scanning microscope. Such investigations have not been reported before in the medical literature.The observed de-epithelialization of most of the membrance and of the ossicles and the distortion of the joints in the transmission apparatus are considered to be results of the prolonged preservation in sialit. The mesenchymal structures are well preserved and this may indicated that, after grafting, revasuclarization occurs along the lumina of the ‘empty’ vessels.Becuase of this finding it might be considered that the maximum duration of preservation in sialit should be no longer than 10–12 months.

The migration theory of cholesteatoma formation. Some experimental observations
Authors: O'Donoghue Gerard M. 
Published: November 2007

AbstractThe migration theory of cholesteatoma formation considers that stratified squamous epithelium from the external auditory meatus migrates into the middle ear, giving rise to cholesteatoma. To test the ability of squamous epithelium to migrate in this manner, 73 stains were placed in relation to 23 chronic perforations. In no instance did epithelium migrate into the middle ear cleft. The limitations of the migration theory are discussed.
Middle ear adenoma: A case report with ultrastructural findings
Authors: Bailey Quentin R. , Weiner John M. 
Published: November 2007

AbstractA 56-year-old woman presented with unilateral tinnitus and hearing loss for 18 months. A middle ear mass was detected clinically. At operation, the tumour was found to have eroded the stapes. The light and electron microscopic features of the tumour were those of a middle ear adenoma. This rare benign tumour has an excellent prognosis. Erosion of an ossicle has not been previously associated with this tumour.Benign adenomatous tumours arising from middle ear mucosa are rare (Mills and Fechner, 1984). The term adenoma of middle ear was proposed by Hyams and Michales (1976), and their review of 20 cases emphasized the benign behaviour of these tumours. We report a case of middle ear adenoma in which ossicular erosion occurred.
Serum phosphohexose isomerase levels in patients with head and neck cancer

Published: November 2007

AbstractSerum phosphohexose isomerase (PHI) levels were estimated in 28 patients with head and neck cancer. The mean value was significantly higher when compared to the controls. There was no difference in mean PHI value with respect to the character of the lesion or with the histopathological type of growth. The activity was increased with the advancement of the stage of cancer.With radiotherapy, a gradual and significant decrease in serum PHI activity was observed.

Published: November 2007

SummaryThe process of development of the crista ampullaris has been investigated in the mouse using SEM.Cristae ampullaris of the CBA/CBA mice, from the 13.5th gestational day to the day 2 weeks by were studied.On the 13.5th gestational day, there were numerous microvilli and a primary cilium on the crista ampullaris. Sensory hairs first appeared on the 14.5th gestational day. The kinocilium and stereocilia were short and the length of the stereocilia was almost constant. The formation of the cupula, which had fine networklike structures, started on the 14.5th gestational day.
Vestibular nerve section and saccus decompression: An evaluation of long-term results

Published: November 2007

AbstractThe 1972 AAOO committee (Alford, 1972) guidelines brought some uniformity into the evaluation of therapy for Meniere's Disease. We have adhered to its recommendations in this long-term follow-up report of 21 saccus decompressions and 29 vestibular nerve sections performed on 46 patients between 1968 and 1977. Comparisons between these and other groups have been possible with regard to: 1. control of vertigo; 2. hearing; 3. tinnitus; and 4. development of hydrops in the contralateral ear. All the vestibular nerve section group have enjoyed sustained relief from vertigo. Class D results (recurrent vertigo) account for 14 per cent of the saccus decompression group at one year and 29 per cent at eight to 10-year follow-up. Hearing levels in both groups deteriorated in parallel as time progressed but tinnitus became less noticeable. Nineteen per cent of the long-term review patients showed evidence of developing cochlear hydrops in the contralateral ear. Conservative surgical procedures should be employed whilst any useful hearing exists, though the emphasis remains on controlling vertigo. Saccus decompression, despite its controversial therapeutic basis, will remain the first-line surgical procedure for many otologists. However, in the fit young Meniere's cripple or saccus decompression failure with serviceable hearing, vestibular nerve section remains the treatment of choice.
The role of radiography in the management of nasal fractures
Authors: Clayton M. I. , Lesser T. H. J. 
Published: November 2007

AbstractThe role of radiographs in the management of nasal fractures is assessed. The inj ury is common and the total cost of radiographs significant. A retrospective study concluded that radiographs were not definitive in the management of nasal fractures. This prompted a prospective study, in which 54 patients were assessed clinically, radiologically and under anaesthesia. At each stage they were grouped into treatment and pathological categories and the contribution of each type of assessment studied. Radiographs were not found to be useful in the routine management of nasal fractures.
