Objectives: Tinnitus can adversely affect patients' quality of life. Transcutaneous electrical nerve stimulation (TENS) may be effective in the management of tinnitus. No study has investigated the efficacy of TENS for the management of tinnitus by means of quality of life measures. In this study, we evaluated the efficacy of TENS for the management of tinnitus symptoms by using the visual analogue scale (VAS), tinnitus handicap inventory test, Nottingham health profile (NHP) and short form-36 (SF-36) questionnaires.

Methods: Twenty-two patients were included in this study (male/female, 16/6; mean age, 48.04 ± 15.57 years). Nine patients had unilateral and 13 patients had bilateral tinnitus.

Results: After TENS, improvement measured by VAS was only marginally significant (p = 0.059). However, after TENS, there were statistically significant improvements regarding tinnitus severity scores, tinnitus handicap inventory scores, NHP fatigue, social isolation and emotional problems scores, and many parameters measured by the SF-36 (physical functioning, general health, vitality, social functioning, role limitations due to emotional problems, and mental health)(p < 0.05).

Conclusion: Transcutaneous electrical nerve stimulation is a useful method to improve the quality of life of patients with tinnitus.

Objective: To assess the association between the habitual head position during bedrest and the affected ear in benign paroxysmal positional vertigo (BPPV).

Study design: Prospective trial of patients with active BPPV of the posterior semicircular canal, confirmed on physical examination.

Methods: Seventy-five patients were asked to explain the head position and lying side they were accustomed to before falling asleep in bed.

Results: Fifty patients (67 per cent) habitually adopted a lateral head position during bedrest. The ear affected by BPPV was found to be consistent with the head-lying side during bedrest in 43 cases (86 per cent) (29 cases for the right ear and 14 cases for the left ear).

Conclusion: Habitual lateral head-positioning during bedrest can be a major factor leading to the development of BPPV in the ipsilateral ear.

The purpose of this study was to compare the prevalence of ear, nose and particularly voice problems in groups of children with cleft palate (CP) and with unilateral cleft lip, alveolus and palate (UCLP). On the basis of history, regular otorhinolaryngological examinations and hearing tests, the prevalence of different pathologies was assessed in 80 CP children (35 boys and 45 girls) and 73 UCLP children (47 boys and 26 girls). Ear pathology was reported in 53.8 per cent of CP children and in 58.9 per cent of UCLP children. Nasal breathing was impaired in 14 CP (17.5 per cent) and 36 UCLP (49.3 per cent) children. Dysphonia was detected in 12.5 per cent of CP and 12.3 per cent of UCLP children. In 9.2 per cent of all cleft children, functional voice disorder caused a hoarse voice. Two-thirds of cleft children with functional dysphonia had protracted hearing loss. Therefore, ENT specialists must take an active role early in the treatment of children with clefts.

The pathogenesis of Ménière's disease is associated with a disorder of ionic homeostasis, with the pathologic correlate being endolymphatic hydrops. Despite uncertainty as to its particular mode of action, it is accepted wisdom that intra-tympanic gentamicin has a definite therapeutic role in the control of symptoms in patients who fail to respond to medical therapy. This study reports an evaluation of the efficacy of intra-tympanic gentamicin in the treatment of Ménière's disease and also presents a simple, reliable, safe method of administering gentamicin for this purpose.

A retrospective review of 56 patients undergoing intra-tympanic gentamicin treatment for Ménière's disease was conducted. Response to treatment was analysed using a patient survey and examination of pure-tone averages. An overall significant improvement in vertigo symptoms of 81.3 per cent was found. There was a 21.4 per cent rate of significant hearing loss, defined as greater than 10 dB, with an average loss in this group of 18.5 dB. A single dose of gentamicin applied directly to the round window resulted in a high rate of control of vertigo, with acceptably low rates of hearing loss.

Objective: The aim of this study was to identify the distribution of parotid tumours within the gland in relation to the facial nerve branches. Documentation revealing such a relationship has not been reported previously.

Method: A prospective study involving 111 patients was carried out over a period of 18 years in a specialist otolaryngology unit within a district general hospital. The relationship of the facial nerve to the tumour was graded into six types. The grading system was then employed to categorize each case.

Results: More than two-thirds of the tumours were pleomorphic adenomas. The majority of these were located in the body and not in the tail of the parotid gland. In 50 per cent of these cases, the tumour was in close association with the two major divisions of the facial nerve. In the case of Warthin's tumours, 47 per cent were located in the tail, below the lower division of the facial nerve.

Within the last 10 to 15 years, a significant amount of research in tonsil surgery has focused on reduction of post-operative pain and recovery time. In order to minimize or avoid morbidity, a number of otolaryngologists in the United States and Europe have revived a historical procedure, previously known as ‘tonsillotomy’, specifically for those patients with obstructive sleep-disordered breathing (OSDB) due to adenotonsillar hypertrophy. More recently, surgeons have used terms such as partial tonsillectomy, partial intracapsular tonsillectomy or subtotal tonsillectomy to describe their procedure and have employed a variety of modern instrumentation. This return to a ‘partial’ procedure has generated a debate similar to that which occurred amongst tonsil surgeons about 100 years ago, when tonsillotomy was the most commonly performed procedure. Today, concerns about regrowth and problems with infection of the remaining tonsillar tissue have been raised. Such concerns, combined with an incomplete understanding of why the ‘partial’ procedure was abandoned in the early twentieth century, may explain why tonsil surgeons hesitate to change their approach to patients with OSDB due to adenotonsillar hypertrophy. These issues can be addressed in a meaningful way only through a detailed review of the evolution of tonsil surgery, which is presented here. This information, along with a summary of the last 10 years' experience with these techniques, supports the use of a ‘partial’ procedure in children with OSDB due to adenotonsillar hypertrophy. Future areas of research are also discussed.

Objective: To investigate the location of the scala media in relation to the round window niche in human temporal bones.

Design: Ten human temporal bones were investigated by radical mastoidectomy and promontory drill-out.

Setting: Temporal bone laboratory.

Outcome measures: The distance from the scala media to the anterior edge of the round window niche, measured by Fisch's stapedectomy measuring cylinders.

Results: The scala media was identified at the transection point of a vertical line 1.6 to 2.2 mm (mean=1.8 mm; standard deviation=0.2) anterior to the anterior edge of the round window niche and a horizontal line 0.2 mm inferior to the lower border of the oval window.

Conclusion: This report demonstrates the point of entry into the scala media via the promontory in fixed temporal bone models, which may provide a site of entry for stem cells and gene therapy insertion.

Objective: The aim of this study was to assess the experiences and outcomes of patients receiving intratympanic gentamicin treatment for Ménière's disease in Norfolk, UK.

Design: This study was based on a retrospective questionnaire survey and a review of patients' medical records.

Setting: Two district hospitals.

Participants: All 29 patients treated between 1999 and 2001, with a minimum follow up of two years post-treatment, were included in the study. Twenty-three patients completed the questionnaires (79 per cent response rate).

Main outcome measures: Glasgow benefit inventory (GBI) and vertigo symptom scale (VSS) scores, plus change in hearing thresholds.

Results: The mean GBI total score was +36, indicating substantial improvement in patients' overall quality of life following gentamicin treatment. The VSS scores demonstrated low levels of vertigo or unsteadiness in treated patients. Three patients suffered deterioration in their hearing thresholds following a single injection of gentamicin. However, 96 per cent of responders stated that they would be willing to have such treatment again, if necessary.

Conclusion: Intratympanic gentamicin treatment ought to be offered to Ménière's patients suffering from disabling vertigo, with the proviso that they be made aware of the possibility of hearing deterioration.

Aim: To evaluate the reliability of infrared tympanic thermometry in children who have undergone myringotomy with grommet insertion.

Method: Forty children who had undergone myringotomy with at least one grommet insertion had the tympanic temperature of each ear and the axillary temperature measured on admission and 30 minutes post-operatively.

Result: No difference was found between the pre- and post-operative temperatures measured by either method (p > 0.05, paired t-test, hypothesized difference of 0).

Conclusion: Infrared tympanic thermometry is reliable in monitoring body temperature in children who have had minor ear surgery.

In recent years, near-infrared spectroscopy (NIRS) has been used to study functional activation of various areas of the brain. This is based on the assumption that an increase in the recorded oxygenated haemoglobin (HbO2) concentration represents an increase in blood flow, which in turn reflects neuronal activation. The aim of this preliminary study was to use NIRS to monitor the activity of the olfactory cortex, as mirrored by the haemodynamic response, when subjects were exposed to olfactory stimuli.

A NIRO 300 (Hamamatsu Photonics, Hamamatsu, Japan) device was used. The optodes were placed on the right forehead and right temporal, parietal and occipital regions. Changes in the concentration of HbO2 and deoxygenated haemoglobin during olfactory stimulation were monitored. Olfactory stimulation was performed with vanilla essence, strawberry essence and scatol.

During olfactory stimulation, cerebral HbO2 concentration increased over the frontal region. However, in the temporal, parietal and occipital regions, little or no HbO2 changes were recorded.

This study shows that human brain cortical activation following olfactory stimulation can be recorded by NIRS. This NIRS analysis may therefore provide the basis for future development of an objective olfactory test in humans.

Mobile telephones are now an integral part of modern telecommunications. The widespread use of mobile telephones has given rise to concern about the potential influences of electromagnetic fields (EMFs) on human health. The effects of EMFs on human beings are under investigation. Anatomically, the ear is in close proximity to the mobile telephone during use. The effect of mobile phones on auditory function has rarely been studied. The aim of this review is to determine if there is evidence that mobile phones have a detrimental effect on auditory function.

This study was conducted with an aim to assess the prevalence and profile of ear diseases in children from the higher and lower socioeconomic strata of society. Two groups of schools within Delhi were selected. Group A comprised of government schools located in slum areas with an average parental income of INR (Indian National Rupees) 1050 per month and group B of elite private schools with an average family income of TNR 35 000 per month. Three thousand children between the ages of 5–12 years were screened with the help of a written proforma and ear examination. Tympanometry and audiometry were done, where required. 19.6 per cent of children of group A were found to be suffering from ear diseases compared to 2.13 per cent of group B children. The two groups were also compared for number of family members, status of hygiene and parental education.

Bilateral abductor vocal fold paralysis (BAVFP) is a rare but life-threatening condition which may require an emergency tracheotomy procedure. The ideal surgical technique for this condition should improve quality of life by relieving the airway obstruction while preserving laryngeal functions such as phonation and deglutition. Posterior transverse laser cordotomy (PTLC) was first described by Dennis and Kashima as a technique for providing an airway at the posterior glottis without pre-operative tracheotomy; they reported it as a successful method with satisfactory functional results. The aim of this prospective study was to evaluate long term acoustic, aerodynamic and functional results of the primary bilateral PTLC technique in 22 BAVFP patients. Severity of dyspnoea was evaluated using a five-level subjective symptom scale graded according to the limitation in daily activity and level of respiratory difficulty. Aerodynamic and acoustic analyses were performed pre-operatively and prospective changes in aerodynamic and acoustic parameters were collected after one post-operative year.

Objective: To identify any prospective, controlled trials providing objective evidence of a reduction in nasal airway resistance following nasal septal surgery, and to undertake a meta-analysis of available data.

Methods: A systematic review with meta-analysis of data was undertaken. A systematic review of the literature using a defined search strategy was conducted to identify papers that used objective methods of airway assessment to evaluate the benefit of septal surgery. Accepted techniques for objective airway assessment included acoustic rhinometry, active anterior rhinomanometry and peak nasal inspiratory airflow. Papers were included based on pre-defined criteria, which included standardization of techniques as outlined in the guidelines of the 1984 committee report on the standardization of rhinomanometry.

Results: We identified 942 articles, of which 13 were prospective studies evaluating the objective benefit of nasal septal surgery. Only three of these studies conformed to the inclusion criteria. A meta-analysis on these papers was performed using the Mantel–Haenszel method, and this demonstrated an overall reduction in nasal airway resistance following septal surgery for nasal obstruction (p=0.018).

Conclusions: The majority of studies evaluating the objective benefit of septal surgery did not conform to the recommendations of the committee report on the standardization of rhinomanometry. Only three prospective controlled trials, with pooled data from 141 cases, were identified for meta-analysis. The conclusions that can be drawn concerning objective improvement in airway function following nasal septal surgery are therefore limited. More long-term studies, adhering to standardized techniques, are needed to provide more convincing data.

Objectives: To report the clinical results of a bone-anchored hearing aid (BAHA) programme in a district general hospital, compared with those in an established, large, university teaching hospital centre.

Design: A retrospective postal questionnaire sent to BAHA patients, with two month waiting time and one reminder, combined with case note analysis. Results compared by appropriate statistical tests with published outcomes data from the largest UK series.

Setting: Public sector (National Health Service) district general hospital, England. Catchment population: 300 000 (mixed rural and small towns).

Participants: Case note analysis of sixty-three patients implanted between 1994 and 2003 (age range, six to 88 years). The commonest indication was chronic otitis media, with inability to wear a conventional hearing aid. Otitis externa, otosclerosis and sensorineural hearing loss were other indications. The questionnaire was sent to 59 patients who had worn their aid for at least six months; it was returned by 41 (69 per cent).

Main outcome measures: Glasgow benefit inventory (GBI, change in health status following otolaryngological intervention); incidence of complications.

Results: Bone-anchored hearing aid implantation significantly improved quality of life as measured by the GBI (p < 0.001). The degree of improvement was similar to that achieved in Birmingham by Proops et al. (p > 0.05, chi-squared test). Minor temporary skin infection was common (33 per cent). Thickening of the skin around the implant occurred in 17 per cent. One implant (2 per cent) failed. There were no serious complications.

Conclusion: The BAHA is a safe, reliable and effective treatment for selected patients. A successful BAHA programme can be run in a district general hospital.

Objective: To note the incidence of middle-ear barotrauma following standard and slow compression during hyperbaric oxygen therapy (HBOT). The standards used were: (1) less than 40 per cent of the cohort should develop barotraumas, and (2) the incidence of barotrauma following the slow technique should be less than that caused by the standard technique.

Design: Prospective clinical audit.

Material and methods: Forty-two consecutive patients who received either standard compression or slow compression HBOT were included. Pre- and post-treatment otoscopy (graded according to a modified Teed's scale), tympanometry, audiometry and subjective ear complaints were compared between the groups and also compared with the set standard.

Results: Significantly less middle-ear barotrauma was noted when using the slow compression technique compared with the standard compression technique (p < 0.05). The incidence of barotrauma when using standard compression failed to meet the set standard of less than 40 per cent.

Conclusion: The slow compression method of HBOT proved to be both safe and superior to the standard compression technique.

The aim of this study was to investigate otoacoustic emissions in young adults who had a history of otitis media (OM) in childhood and to assess whether a history of OM had an irreversible effect on hearing. We studied 116 cases between 15 and 25 years of age, divided into three groups. Each subject underwent a single examination comprising otoscopy, pure-tone audiometry (PTA), tympanometry, and transient evoked otoacoustic emission (TEOAE) and distortion product otoacoustic emission (DPOAE) testing. Subjects in the first and second groups had normal audiometric hearing thresholds and type A tympanograms. The only difference between the first and second group was the presence or absence of a history of OM. The third group consisted of patients diagnosed as having active OM; these patients had poorer hearing thresholds and type B or C tympanograms. After statistical analysis of TEOAE and DPOAE results (one-way analysis of variance test), significant differences were noted between groups. Otoacoustic emission levels were, unsurprisingly, lowest in the third group, as expected. However, the most striking result in the study was that significantly fewer otoacoustic emissions were detected in subjects with a history of OM than in subjects without a history of OM. These findings suggest that OM in childhood may cause minor but irreversible damage to the middle ear or cochlea. Otoacoustic emissions testing can be used to detect this sub-clinical damage.

Background: Seeking to identify where litigious claims against otolaryngologists are targeted (i.e. areas of highest risk) within the NHS and private sector would have positive implications in risk management and limiting the amount of litigation against otolaryngologists.

Method: The National Health Service Litigation Authority (NHSLA) and Medical Defence Union (MDU) were contacted and anonymous data obtained on claims within ENT.

Results: 887 claims were notified – 457 NHSLA and 430 MDU. The commonest claim in both groups was failure or delay in diagnosis (12 per cent NHSLA, 23 per cent MDU). The other commonest claims were all related to complications (nerve damage 10 per cent, deafness 8 per cent and dental damage 5 per cent). Dissatisfaction with results was 8 per cent total and, within the private sector, was almost exclusively in rhinology.

Conclusions: This study once again emphasizes the need for thorough clinical assessment, record keeping and good communication with patients. Recognising these areas of highest risk may limit future claims.

Previously, the hypoglossal nerve has not undergone intra-operative monitoring during neck operations in which the nerve is at risk. As society becomes increasingly litigious, this may change. This study describes the technique and the microvoltages used in 10 patients for intra-operative stimulation of the hypoglossal nerve with the Magstim nerve stimulator. We confirm that the technique is possible, simple and safe, with minimal disturbance to the patient, anaesthetist and surgeon.

Tympanoplasty is often a necessary part of middle-ear surgery, the most common defect being that between an intact, mobile stapes and the malleus handle. The most readily available tissue is the patient's incus, reshaped to bridge the space between an intact stapes and the malleus. When the incus cannot be used, the hydroxyapatite Wehrs incus prosthesis® can be used as an alternative.

Twenty-six patients had an autograft incus ossiculoplasty and 20 patients underwent modified Wehrs incus prosthesis ossiculoplasty. The average post-operative air–bone gaps (ABGs) were 16.2 dB hearing loss (dBHL) and 17.2 dBHL, respectively. Air–bone gap closure to within 15 dBHL was achieved for 48 per cent of incus autografts and for 57 per cent of Wehrs prostheses, and to within 20 dBHL for 77 per cent and 62 per cent, respectively. Over four years follow up, the reconstruction was stable for each group, the ABGs being 17.7 dBHL and 17.1 dBHL, respectively.
