A Near-Peer Teaching Module to Supplement Current Undergraduate Teaching in ENT Surgery

BACKGROUND

Near-peer teaching (NPT) has been successfully used in other medical specialties but not in ear, nose and throat surgery (ENT). Historically, undergraduates receive limited ENT exposure and subsequently report low confidence in ENT competencies. This has been a posited cause of high referral rates to the specialty. This study aimed to see if NPT could be implemented as an adjunct to traditional ENT teaching.

ACTIVITY

Learners received a short NPT module that was focused on clinical ENT. Pre- and post-module questionnaires collected data on students' confidence and knowledge.

RESULTS AND DISCUSSION

One hundred twenty-five undergraduate learners received the intervention. There was a significant percentage increase in both confidence (24.2%, p = < 0.001) and knowledge (35.9%, p = < 0.001) of learners. In a supervised setting, NPT could be a valuable adjunct to traditional undergraduate ENT education.

Is it safe to inject local anaesthetic with adrenaline into the pinna and external nose?

Adrenaline containing lidocaine preparations such as lignospan are routinely used in ear, nose and throat (ENT) care. Despite this, textbooks and internet resources warn against their use in peripheries, including the nose and ear. As a result, they are commonly avoided by other specialties, such as emergency medicine. This article reports on the findings of a review undertaken to assess the evidence of harm associated with using lignospan in the pinna and external nose. A literature search was carried out, and retrospective data were collected on all elective facial skin lesion surgery in the ENT department at the Great Western Hospital in Swindon between 2005 and 2015. Cases using lignospan in the pinna and nose were included. The literature search revealed no reports of ischaemic complications of the pinna or nose following use of lignospan, or similar preparation. Of the 1,409 cases collected, no ischaemic complications were recorded. The article concludes that adrenaline containing lidocaine preparations such as lignospan are safe for use in the pinna and nose, and should be considered for use in emergency departments.

Interventions for children with ear discharge occurring at least two weeks following grommet (ventilation tube) insertion

BACKGROUND

Ear discharge (otorrhoea) is common in children with grommets (ventilation/tympanostomy tubes); the proportion of children developing discharge ranges from 25% to 75%. The most common treatment strategies include oral broad-spectrum antibiotics, antibiotic eardrops or those containing a combination of antibiotic(s) and a corticosteroid, and initial observation. Important drivers for one strategy over the other are concerns over the side effects of oral antibiotics and the potential ototoxicity of antibiotic eardrops.

OBJECTIVES

To assess the benefits and harms of current treatment strategies for children with ear discharge occurring at least two weeks following grommet (ventilation tube) insertion.

SEARCH METHODS

The Cochrane ENT Information Specialist searched the ENT Trials Register, CENTRAL (2016, Issue 5), multiple databases and additional sources for published and unpublished trials (search date 23 June 2016).

SELECTION CRITERIA

Randomised controlled trials comparing at least two of the following: oral antibiotics, oral corticosteroids, antibiotic eardrops (with or without corticosteroid), corticosteroid eardrops, microsuction cleaning of the ear canal, saline rinsing of the ear canal, placebo or no treatment. The main comparison of interest was antibiotic eardrops (with or without corticosteroid) versus oral antibiotics.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. Primary outcomes were: proportion of children with resolution of ear discharge at short-term follow-up (less than two weeks), adverse events and serious complications. Secondary outcomes were: proportion of children with resolution of ear discharge at intermediate- (two to four weeks) and long-term (four to 12 weeks) follow-up, proportion of children with resolution of ear pain and fever at short-term follow-up, duration of ear discharge, proportion of children with chronic ear discharge, ear discharge recurrences, tube blockage, tube extrusion, health-related quality of life and hearing. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics.

MAIN RESULTS

We included nine studies, evaluating a range of treatments, with 2132 children who developed acute ear discharge beyond the immediate postoperative period. We judged the risk of bias to be low to moderate in most studies. Antibiotic eardrops (with or without corticosteroid) versus oral antibioticsAntibiotic eardrops with or without corticosteroid were more effective than oral antibiotics in terms of:- resolution of discharge at one week (one study, 42 children, ciprofloxacin eardrops versus amoxicillin: 77% versus 30%; risk ratio (RR) 2.58, 95% confidence interval (CI) 1.27 to 5.22; moderate-quality evidence);- resolution of discharge at two weeks (one study, 153 children, bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: 95% versus 56%; RR 1.70, 95% CI 1.38 to 2.08; moderate-quality evidence);- duration of discharge (two studies, 233 children, ciprofloxacin eardrops versus amoxicillin: median 4 days versus 7 days and bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: 4 days versus 5 days; moderate-quality evidence);- ear discharge recurrences (one study, 148 children, bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: 0 versus 1 episode at six months; low-quality evidence); and- disease-specific quality of life (one study, 153 children, bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: difference in change in median Otitis Media-6 total score (range 6 to 42) at two weeks: -2; low-quality evidence).We found no evidence that antibiotic eardrops were more effective in terms of the proportion of children developing chronic ear discharge or tube blockage, generic quality of life or hearing.Adverse events occurred at similar rates in children treated with antibiotic eardrops and those treated with oral antibiotics, while no serious complications occurred in either of the groups. Other comparisons(a) Antibiotic eardrops with or without corticosteroid were more effective thancorticosteroid eardrops in terms of:- duration of ear discharge (one study, 331 children, ciprofloxacin versus ciprofloxacin-fluocinolone acetonide versus fluocinolone acetonide eardrops: median 5 days versus 7 days versus 22 days; moderate-quality evidence).(b) Antibiotic eardrops were more effective than saline rinsing of the ear canal in terms of:- resolution of ear discharge at one week (one study, 48 children, ciprofloxacin eardrops versus saline rinsing: 77% versus 46%; RR 1.67, 95% CI 1.04 to 2.69; moderate-quality evidence);but not in terms of tube blockage. Since the lower limit of the 95% CI for the effect size for resolution of ear discharge at one week approaches unity, a trivial or clinically irrelevant difference cannot be excluded.(c) Eardrops containing two antibiotics and a corticosteroid (bacitracin-colistin-hydrocortisone) were more effective than no treatment in terms of:- resolution of discharge at two weeks (one study; 151 children: 95% versus 45%; RR 2.09, 95% CI 1.62 to 2.69; moderate-quality evidence);- duration of discharge (one study; 147 children, median 4 days versus 12 days; moderate-quality evidence);- chronic discharge (one study; 147 children; RR 0.08, 95% CI 0.01 to 0.62; low-quality evidence); and- disease-specific quality of life (one study, 153 children, difference in change in median Otitis Media-6 total score (range 6 to 42) between groups at two weeks: -1.5; low-quality evidence).We found no evidence that antibiotic eardrops were more effective in terms of ear discharge recurrences or generic quality of life.(d) Eardrops containing a combination of an antibiotic and a corticosteroid were more effective than eardrops containing antibiotics (low-quality evidence) in terms of:- resolution of ear discharge at short-term follow-up (two studies, 590 children: 35% versus 20%; RR 1.76, 95% CI 1.33 to 2.31); and- duration of discharge (three studies, 813 children);but not in terms of resolution of discharge at intermediate-term follow-up or proportion of children with tube blockage. However, there is a substantial risk of publication bias, therefore these findings should be interpreted with caution.

AUTHORS' CONCLUSIONS

We found moderate to low-quality evidence that antibiotic eardrops (with or without corticosteroid) are more effective than oral antibiotics, corticosteroid eardrops and no treatment in children with ear discharge occurring at least two weeks following grommet insertion. There is some limited, inconclusive evidence that antibiotic eardrops are more effective than saline rinsing. There is uncertainty whether antibiotic-corticosteroid eardrops are more effective than eardrops containing antibiotics only.

WITHDRAWN: Interventions for ear discharge associated with grommets (ventilation tubes)

BACKGROUND

The insertion of grommets (also known as ventilation or tympanostomy tubes) is one of the most common surgical procedures performed on children. Postoperative otorrhoea (discharge) is the most common complication with a reported incidence ranging from 10% to 50%. In the UK, many ENT surgeons treat with topical antibiotics/steroid combinations, but general practitioners, mainly through fears of ototoxicity, are unlikely to prescribe these and choose systemic broad-spectrum antibiotics.

OBJECTIVES

1. To identify the most effective non-surgical management of discharge from ears with grommets in place.2. To identify the risks of non-surgical management for this condition (e.g. ototoxicity), and to set benefits of treatment against these risks.

SEARCH METHODS

We searched the Cochrane Ear, Nose and Throat Disorders Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2005), MEDLINE (1966 to 2005) and EMBASE (1974 to 2005). We also searched the CINAHL, AMED, LILACS, ISI WEB OF KNOWLEDGE, ISI PROCEEDINGS, mRCT, NNR, ZETOC, KOREAMED, CSA, MEDCARIB, INDMED and SAMED databases. The date of the last search was February 2005.

SELECTION CRITERIA

Randomised controlled trials of adults or children, with any type of grommet and an ear with discharge were included. The trials compared treatment with placebo or one treatment with another. The primary outcome measure was the duration of the discharge.

DATA COLLECTION AND ANALYSIS

The trials were selected independently according to the above criteria by the four reviewers. Differences in opinion over the inclusion of studies were resolved by discussion. The studies were graded using the CASP critical appraisal tool. Analyses were based on the presence of discharge seven days from the onset of treatment.

MAIN RESULTS

There was very little good quality evidence. Four studies were included, all of them investigating different interventions and therefore a meta-analysis was not possible.Only one study demonstrated a significant difference. Oral amoxicillin clavulanate was compared to placebo in 79 patients. The odds of having a discharge persisting eight days after starting treatment was 0.19 (95% CI 0.07 to 0.49) . The number needed to treat to achieve that benefit is 2.5. Participants in both arms of this study also received daily aural toilet. The results will therefore not be applicable to most settings including primary care. No significant benefit was shown in the two studies investigating steroids (oral prednisolone with oral amoxicillin clavulanate and topical dexamethasone with topical ciprofloxacin ear drops), or the one study comparing an antibiotic-steroid combination (Otosporin®) drops versus spray (Otomize®) (although more patients preferred the spray form).

AUTHORS' CONCLUSIONS

The authors of this review have been unable to identify the most effective intervention or to assess the associated risks. Research is urgently needed into the effectiveness of oral versus topical antibiotics in this group of patients. Clinicians considering antibiotic treatment need to balance any potential benefit against the risks of side effects and antibiotic resistance.

A review of the diagnosis and management of sudden hearing loss in the military population

Sudden hearing loss can be both an immediately debilitating and long-term career-threatening condition within the military population. Careful assessment is key, particularly in an environment where heightened occupational risk factors may contribute to or confound diagnoses, and where access to basic investigation may be limited. This article looks at the patient with a new presentation of sudden hearing loss in a military setting and, by providing key features and a structured approach to examination and basic investigation, how to consider key diagnoses through clinical assessment alone. The acute management of sudden sensorineural hearing loss (SNHL) remains a difficult issue, particularly regarding the efficacy of treatment regimes to restore hearing. We have reviewed the evidence to help military medical personnel make well-informed decisions when treating and making occupational assessment of those they have diagnosed with sudden hearing loss.

Tinnitus

INTRODUCTION

Up to 18% of people in industrialised societies are mildly affected by chronic tinnitus, and 0.5% report tinnitus having a severe effect on their daily life. Tinnitus can be associated with hearing loss, acoustic neuromas, drug toxicity, ear diseases, and depression. Tinnitus can last for many years, and can interfere with sleep and concentration.

METHODS AND OUTCOMES

We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for chronic tinnitus? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found 33 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review, we present information relating to the effectiveness and safety of the following interventions: acamprosate, acupuncture, antidepressant drugs, benzodiazepines, carbamazepine, electromagnetic stimulation, ginkgo biloba, hearing aids, hypnosis, psychotherapy, tinnitus-masking devices, and cognitive behavioural therapy plus tinnitus-masking device (tinnitus retraining therapy).

Corticosteroids for the treatment of idiopathic acute vestibular dysfunction (vestibular neuritis)

BACKGROUND

Idiopathic acute vestibular dysfunction (vestibular neuritis) is the second most common cause of peripheral vertigo after benign paroxysmal positional vertigo (BPPV) and accounts for 7% of the patients who present at outpatient clinics specialising in the treatment of dizziness. The exact aetiology of the condition is unknown and the effects of corticosteroids on the condition and its recovery are uncertain.

OBJECTIVES

To assess the effectiveness of corticosteroids in the management of patients with idiopathic acute vestibular dysfunction (vestibular neuritis).

SEARCH STRATEGY

We searched the Cochrane ENT Group Trials Register; CENTRAL; PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 28 December 2010.

SELECTION CRITERIA

Randomised controlled trials comparing corticosteroids with placebo, no treatment or other active treatments, for adults diagnosed with idiopathic acute vestibular dysfunction.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies from the search results and extracted data. Three authors independently assessed risk of bias.

MAIN RESULTS

Four trials, involving a total of 149 participants, compared the effectiveness of oral corticosteroids against placebo. All the trials were small and of low methodological quality. Although there was an overall significant effect of corticosteroids compared with placebo medication on complete caloric recovery at one month (risk ratio (RR) of 2.81; 95% confidence interval (CI) 1.32 to 6.00, P = 0.007), no significant effect was seen on complete caloric recovery at 12 months (RR 1.58; 95% CI 0.45 to 5.62, P = 0.48), or on the extent of caloric recovery at either one month (mean difference (MD) 9.60%; 95% CI -20.66 to 39.86, P = 0.53) or at 12 months (MD 6.83%; 95% CI -27.69 to 41.36, P = 0.70). In addition, there was no significant difference between corticosteroids and placebo medication in the symptomatic recovery of vestibular function following idiopathic acute vestibular dysfunction with respect to vertigo at 24 hours (RR 0.39; 95% CI 0.04 to 3.57, P = 0.40) and use of the Dizziness Handicap Inventory score at one, three, six and 12 months.

AUTHORS' CONCLUSIONS

Overall, there is currently insufficient evidence from these trials to support the administration of corticosteroids to patients with idiopathic acute vestibular dysfunction. We found no trials with a low risk of methodological bias that used the highest level of diagnostic criteria and outcome measures. We recommend that future studies should include health-related quality of life and symptom-based outcome measures, in addition to objective measures of vestibular improvement, such as caloric testing and electronystagmography.

Cognitive behavioural therapy for tinnitus

BACKGROUND

This is an update of a Cochrane Review originally published in Issue 1, 2007 of The Cochrane Library.Tinnitus is an auditory perception that can be described as the experience of sound, in the ear or in the head, in the absence of external acoustic stimulation. Cognitive behavioural therapy (CBT) uses relaxation, cognitive restructuring of the thoughts and exposure to exacerbating situations in order to promote habituation and may benefit tinnitus patients, as may the treatment of associated psychological conditions.

OBJECTIVES

To assess whether CBT is effective in the management of patients suffering from tinnitus.

SEARCH STRATEGY

We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; PsycINFO; ISRCTN and additional sources for published and unpublished trials. The date of the most recent search was 6 May 2010.

SELECTION CRITERIA

Randomised controlled trials in which patients with unilateral or bilateral tinnitus as their main symptom received cognitive behavioural treatment.

DATA COLLECTION AND ANALYSIS

One review author (PMD) assessed every report identified by the search strategy. Three authors (PMD, AW and MT) assessed the methodological quality and applied inclusion/exclusion criteria. Two authors (PMD and RP) extracted data and conducted the meta-analysis. The four authors contributed to the final text of the review.

MAIN RESULTS

Eight trials comprising 468 participants were included.For the primary outcome of subjective tinnitus loudness we found no evidence of a difference between CBT and no treatment or another intervention (yoga, education and 'minimal contact - education').In the secondary outcomes we found evidence that quality of life scores were improved in participants who had tinnitus when comparing CBT to no treatment or another intervention (education and 'minimal contact education'). We also found evidence that depression scores improved when comparing CBT to no treatment. We found no evidence of benefit in depression scores when comparing CBT to other treatments (yoga, education and 'minimal contact - education').There were no adverse/side effects reported in any trial.

AUTHORS' CONCLUSIONS

In six studies we found no evidence of a significant difference in the subjective loudness of tinnitus.However, we found a significant improvement in depression score (in six studies) and quality of life (decrease of global tinnitus severity) in another five studies, suggesting that CBT has a positive effect on the management of tinnitus.

Noise levels generated within the external auditory canal during microsuction aural toilet and the effect on hearing: a prospective controlled series

OBJECTIVES

To measure the noise generated during suction aural toilet and to determine whether there is any clinically measureable effect on audiometric thresholds.

STUDY DESIGN

Prospective, controlled study with 14 patients.

SETTING

The study was conducted in an aural toilet clinic in a district general ENT department.

PARTICIPANTS

Fourteen patients who attend regularly for suction aural toilet to clear cerumen.

MAIN OUTCOME MEASURES

Live direct measurement of noise levels during treatment. Pre-treatment and post-treatment pure tone audiometry.

RESULTS

Microsuction generated a broadband sound with a peak at 2 kHz. Sound levels peaked at over 120 dB(A) in two patients. We found no evidence of any shift in audiometric thresholds following microsuction aural toilet.

CONCLUSIONS

Microsuction is a noisy procedure that is uncomfortable for some patients. However, it does not appear to be sufficiently noisy to produce a clinically detectable threshold shift. We would suggest that it is safe but that the use of non-suction methods or a fine end may on occasion be preferable to improve patient comfort.

Management of upper airway obstruction secondary to warfarin therapy: the conservative approach

Airway obstruction secondary to bleeding from warfarin therapy is difficult to manage and uncommon but has been previously described. Previous reports have emphasized the need for reversal of therapy using vitamin K and fresh frozen plasma (FFP). Where a definitive airway has been required, cricothyroidotomy or tracheostomy seem to have been favoured. Several authors have reported failed attempts at endotracheal intubation due to the obstructive effects of a sublingual haematoma. We report here a case which illustrates how endotracheal intubation can be used successfully under the right conditions. It also highlights the superiority of prothrombin complex concentrate over FFP in achieving rapid reversal of abnormal international normalized ratio in the emergency situation.

Accurate consent for insertion and later removal of grommets

Each year in the UK over 30 000 patients undergo insertion of grommets. The grommet insertion may cause many problems like persistent otorrhoea, scarred drum, retraction pockets and retention. The grommets may be extruded from the middle ears by the normal epithelial migration mechanism once they have served their purpose. These may become infected and require removal. We have analysed the Department of Health Hospital Episode Statistics relating to the insertion and removal of grommets (ventilation tubes). We have shown that 7.6 per cent of patients who have grommets inserted will have grommets removed.

Cognitive behavioural therapy for tinnitus

BACKGROUND

Tinnitus is an auditory perception that can be described as the experience of sound, in the ear or in the head, in the absence of external acoustic stimulation (not usually audible to anyone else). At present no specific therapy for tinnitus is acknowledged to be satisfactory in all patients. Cognitive behavioural therapy (CBT) uses relaxation, cognitive restructuring of the thoughts and exposure to exacerbating situations in order to promote habituation and may benefit tinnitus patients, as may the treatment of associated psychological conditions.

OBJECTIVES

To assess whether cognitive behavioural therapy is effective in the management of patients suffering from tinnitus.

SEARCH STRATEGY

Our search included the Cochrane ENT Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2006), MEDLINE and EMBASE. The last search date was June 2006.

SELECTION CRITERIA

Randomised controlled trials in which patients with unilateral or bilateral tinnitus as main symptom received cognitive behavioural treatment.

DATA COLLECTION AND ANALYSIS

One review author (PMD) assessed every report identified by the search strategy. The four review authors assessed the methodological quality, applied inclusion/exclusion criteria and extracted data.

MAIN RESULTS

Six trials comprising 285 participants were included. 1.

PRIMARY OUTCOME

subjective tinnitus loudness. CBT compared to a waiting list control group: we found no significant difference (Standardised Mean Difference (SMD) 0.06 (95% CI -0.25 to 0.37)). CBT compared to another intervention (Yoga, Education, Minimal Contact - Education and Education): we found no significant difference (SMD 0.1 (95% CI -0.22 to 0.42)).2.

SECONDARY OUTCOMES

a) Depression. CBT compared to a waiting list control group: we found no significant difference in either group (SMD 0.29 (95%CI -0.04 to 0.63)). CBT compared to another intervention (Yoga, Education and Minimal Contact - Education): we found no significant difference (SMD 0.01 (95% CI -0.43 to 0.45)). b) Quality of life: CBT compared to a waiting list control group: we found a significant difference in favour of CBT versus the waiting list group (SMD 0.7 (95% CI 0.33 to 1.08)). CBT compared to another intervention (Education, Minimal Contact - Education and Education): we also found a significant difference between CBT and the other intervention control group (SMD 0.64 (95% CI 0.29 to 1.00)). There were no adverse/side effects reported in any trial.

AUTHORS' CONCLUSIONS

We did not find a significant difference in the subjective loudness of tinnitus, or in the associated depression. However we found a significant improvement in the quality of life (decrease of global tinnitus severity) of the participants, thus suggesting that cognitive behavioural therapy has an effect on the qualitative aspects of tinnitus and contributes positively to the management of tinnitus.
