RESUMEN

INTRODUCTION: To determine the impact of a head-referenced cochlear implant (CI) stimulation system, BalanCI, on balance and postural control in children with bilateral cochleovestibular loss (BCVL) who use bilateral CI. METHODS: Prospective, blinded case-control study. Balance and postural control testing occurred in two settings: (1) quiet clinical setting and (2) immersive realistic virtual environment (Challenging Environment Assessment Laboratory [CEAL], Toronto Rehabilitation Institute). Postural control was assessed in 16 and balance in 10 children with BCVL who use bilateral CI, along with 10 typically developing children. Children with neuromotor, cognitive, or visual deficits that would prevent them from performing the tests were excluded. Children wore the BalanCI, which is a head-mounted device that couples with their CIs through the audio port and provides head-referenced spatial information delivered via the intracochlear electrode array. Postural control was measured by center of pressure (COP) and time to fall using the WiiTM (Nintendo, WA, USA) Balance Board for feet and the BalanCI for head, during the administration of the Modified Clinical Test of Sensory Interaction in Balance (CTSIB-M). The COP of the head and feet were assessed for change by deviation, measured as root mean square around the COP (COP-RMS), rate of deviation (COP-RMS/duration), and rate of path length change from center (COP-velocity). Balance was assessed by the Bruininks-Oseretsky Test of Motor Proficiency 2, balance subtest (BOT-2), specifically, BOT-2 score as well as time to fall/fault. RESULTS: In the virtual environment, children demonstrated more stable balance when using BalanCI as measured by an improvement in BOT-2 scores. In a quiet clinical setting, the use of BalanCI led to improved postural control as demonstrated by significant reductions in COP-RMS and COP-velocity. With the use of BalanCI, the number of falls/faults was significantly reduced and time to fall increased. CONCLUSIONS: BalanCI is a simple and effective means of improving postural control and balance in children with BCVL who use bilateral CI. BalanCI could potentially improve the safety of these children, reduce the effort they expend maintaining balance and allow them to take part in more complex balance tasks where sensory information may be limited and/or noisy.

RESUMEN

The round window region is a critical area of the middle ear; the aim of this paper is to describe its anatomy from an endoscopic perspective, emphasizing some structures, the knowledge of which could have important implications during surgery, as well as to evaluate what involvement cholesteatoma may have with these structures. Retrospective review of video recordings of endoscopic ear surgeries and retrospective database review were conducted in Tertiary university referral center. Videos from endoscopic middle ear procedures carried out between June 2010 and September 2012 and stored in a shared database were reviewed retrospectively. Surgeries in which an endoscopic magnification of the round window region and the inferior retrotympanum area was performed intraoperatively were included in the study. Involvement by cholesteatoma of those regions was also documented based on information obtained from the surgical database. Conformation of the tegmen of the round window niche may influence the surgical view of round window membrane. A structure connecting the round window area to the petrous apex, named the subcochlear canaliculus, is described. Cholesteatoma can invade the round window areas in some patients. Endoscopic approaches can guarantee a very detailed view and allow the exploration of the round window region. Exact anatomical knowledge of this region can have important advantages during surgery, since some pathology can invade inside cavities or tunnels otherwise not seen by instrumentation that produces a straight-line view (e.g. microscope).

RESUMEN

BACKGROUND: Idiopathic sudden sensorineural hearing loss (ISSHL) is characterised by sudden loss of hearing of cochlear or retro-cochlear origin without an identifiable cause. Antivirals are commonly prescribed, but there is no consensus on the treatment regimen or their effectiveness. OBJECTIVES: To determine the effectiveness and side effect profile of antivirals in the treatment of ISSHL. SEARCH METHODS: We systematically searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 5), PubMed, EMBASE, CINAHL and other databases to 12 June 2012. We also scanned the reference lists of identified studies for further trials. SELECTION CRITERIA: Randomised controlled trials comparing different antivirals versus placebo (both with or without other treatment). DATA COLLECTION AND ANALYSIS: Two authors independently extracted data, met to resolve disagreements and contacted study authors for further information. We assessed study risk of bias independently. We considered meta-analysis inappropriate and ultimately not possible due to differing treatment protocols of varying dose and duration, together with differing inclusion criteria and outcome measures between studies. The results of each study are reported individually. MAIN RESULTS: We included four randomised trials (257 participants). The overall risk of bias in the included studies was low. Two trials compared the addition of intravenous acyclovir to a steroid (prednisolone). One included 43 participants, the other 70 patients. Neither demonstrated any hearing improvement with ISSHL. Another (84 patients) did not show any statistically significant difference between groups with the addition of valacyclovir to prednisolone (compared to steroid plus placebo) with respect to change in pure-tone audiogram. Comparing the addition of intravenous acyclovir to hydrocortisone with hydrocortisone alone, the final trial did not show any statistically significant difference between groups (60 patients). No trial documented any serious adverse effects related to the use of antiviral treatment. One study reported slight to moderate nausea equally in the acyclovir and placebo groups (one patient in each). Another reported insomnia, nervousness and weight gain with valacyclovir (number not specified). Even though no meta-analysis was possible, evidence from the four RCTs has demonstrated no statistically significant advantage in the use of antivirals in the treatment of ISSHL. AUTHORS' CONCLUSIONS: There is currently no evidence to support the use of antiviral drugs in the treatment of ISSHL. The four trials included in this review were, however, small and with a low risk of bias. Further randomised controlled trials with larger patient populations, using standardised inclusion criteria, antiviral regimes and outcome measures, are needed in order for adequate meta-analysis to be performed to reach definitive conclusions. A uniform definition of ISSHL should also be established, together with what constitutes adequate recovery.

RESUMEN

BACKGROUND: Tympanic membrane retractions are commonly managed by ENT surgeons. There is currently no consensus as to the indications, timing and options for management of this condition. OBJECTIVES: To study the effectiveness of different surgical options in the management of tympanic membrane retractions. SEARCH STRATEGY: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2010 Issue 1); PubMed (1950 to 2010); EMBASE (1974 to 2010); CINAHL (1982 to 2010); BIOSIS Previews; ISI Web of Science; CAB Abstracts; LILACS; KoreaMed; IndMed; PakMediNet; China National Knowledge Infrastructure; ISCTRN; UKCRN; ICTRP and Google. The date of the search was 17 March 2010. SELECTION CRITERIA: Randomised controlled trials (RCTs) of the surgical management of tympanic membrane retraction pockets in adults or children. Staging of the retraction using a known system must have been performed. Studies of cholesteatoma or perforations were excluded. DATA COLLECTION AND ANALYSIS: Two authors independently collected and analysed data to minimise the effects of selection and reporting bias. MAIN RESULTS: Two RCTs were included, involving 71 participants. The first study showed no statistically significant benefit of cartilage graft tympanoplasty over a watch and wait policy for either disease progression or hearing outcome. The second showed no additional benefit from the insertion of ventilation tubes over cartilage tympanoplasty alone with regards to hearing outcome. AUTHORS' CONCLUSIONS: No evidence currently exists to either support or refute the role of surgery in the management of tympanic membrane retractions. Higher quality studies are much needed to ascertain this.

RESUMEN

OBJECTIVE: To review insights gained from a 21-year experience with gentamicin-induced vestibulotoxicity including differences in vestibulotoxicity between single daily dosing (SDD) and multiple daily dosing (MDD) regimens. STUDY DESIGN: Retrospective case series. SETTING: Tertiary care center. PATIENTS: Patients with gentamicin vestibulotoxicity referred to the Hertz Multidisciplinary Neurotology Clinic between January 1993 and September 2014. INTERVENTION: None. MAIN OUTCOME MEASURES: Spectrum of vestibular dysfunction measured using videonystagmography, vestibular evoked myogenic potentials, video head impulse testing, and magnetic scleral search coil testing. RESULTS: Of 53 patients with gentamicin-induced vestibulotoxicity, 24 received SDD and 29 received MDD treatment. The most common indications for treatment were sepsis, endocarditis, and osteomyelitis. Angular acceleration receptor function (semicircular canals) was more commonly affected than linear acceleration receptor function (otolithic organ of the saccule; 100% vs. 62%). A significant proportion of patients (53%) developed vestibulotoxicity in the absence of nephrotoxicity and 40% experienced vestibulotoxicity in a delayed fashion up to 10 days posttreatment cessation (mean 3.9 ±â€Š0.7). Therapeutic monitoring did not necessarily prevent delayed vestibulotoxicity. Nephrotoxicity was less common for SDD compared with MDD (60% vs. 35%, p = 0.01). However, the SDD group experienced vestibulotoxicity at a lower cumulative dose (6.3 vs. 7.0 g, p = 0.04) and shorter duration of therapy (20.7 vs 29.4 d, p = 0.02). CONCLUSIONS: Our study further highlights important insights regarding gentamicin-induced vestibulotoxicity. While SDD is associated with decreased risk for nephrotoxicity compared with MDD, it confers a higher risk for vestibulotoxicity.

RESUMEN

OBJECTIVES/HYPOTHESIS: The traditional medical care model of "assess and refer" in a sequential fashion fails to recognize the complexities that arise due to overlapping physical and psychiatric comorbidities experienced by patients with chronic dizziness or imbalance, thus resulting in inadequate treatment outcomes. We aimed to evaluate the impact of a novel interdisciplinary approach to care that integrates nursing and psychiatry (INaP) on dizziness-related disability. STUDY DESIGN: Retrospective cohort study. METHODS: We compared the change in clinical assessment scores (i.e., Dizziness Handicap Inventory [DHI], Dizziness Catastrophizing Scale) at approximately 8 months follow-up between those who did (INaP+) and did not receive INaP (INaP-). Data from 229 patients with dizziness or imbalance referred to an interdisciplinary neurotology clinic in Toronto, Ontario, Canada were acquired from August 2012 to December 2016 and January 2011 to December 2013 for the INaP+ and INaP- groups, respectively. RESULTS: A mean group difference in the percentage change in DHI scores was found, with greater reductions in dizziness-related disability in the INaP+ group (n = 121) versus the INaP- group (n = 108). This remained significant after controlling for age, gender, baseline illness severity, and duration between baseline and follow-up visits. CONCLUSIONS: The novel interdisciplinary approach of incorporating INaP appears to be more effective than interdisciplinary care without INaP in reducing dizziness-related disability in patients with chronic dizziness or imbalance. Clinical settings should consider the addition of INaP to achieve better patient outcomes. Future studies are required to test the hypothesis that INaP is more efficient and cost-effective than the traditional model of care. LEVEL OF EVIDENCE: 3 Laryngoscope, 130:1800-1804, 2020.

RESUMEN

OBJECTIVES: The traditional medical care model of "assess and refer" requires revamping to address the multifaceted needs of patients with chronic dizziness and imbalance by adopting an interdisciplinary approach to care that integrates nursing and psychiatry (INaP). We aim to present a novel interdisciplinary approach that incorporates INaP in the care of patients with chronic dizziness and imbalance. METHODS: Presentation of an interdisciplinary model of care that incorporates INaP provided at the Toronto General Hospital in Toronto, Canada. RESULTS: Interdisciplinary care incorporating INaP, which includes the provision of support from an interdisciplinary health care team (ie, neurotologist, neurologist, psychiatrist, physiotherapist, and nurse clinician), psychoeducation about the interaction between chronic dizziness and psychiatric comorbidities, and ongoing access to medical and psychosocial assessment and intervention, addresses the physical and emotional aspects of patients' experience with chronic dizziness. CONCLUSIONS: The novel comprehensive interdisciplinary approach incorporating INaP may be more effective than interdisciplinary care without INaP in improving clinical outcomes in patients with chronic dizziness. In the subsequent study, we present data comparing patients treated for chronic dizziness and imbalance with and without the integration of INaP in an interdisciplinary setting. LEVEL OF EVIDENCE: 5 Laryngoscope, 130:1792-1799, 2020.

RESUMEN

BACKGROUND: Idiopathic sudden sensorineural hearing loss (ISSHL) is sudden hearing loss where clinical assessment fails to reveal a cause. The most widely used therapeutic agents for ISSHL are antivirals, steroids, hyperbaric oxygen, vasodilators and rheological/vasoactive substances. There is currently conflicting evidence for vasodilator and vasoactive substances in the treatment of ISSHL. OBJECTIVES: 1. To determine the effectiveness of vasodilators and other vasoactive substances in improving hearing in patients with ISSHL. 2. To determine the adverse effects of these medications. 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; Cambridge Scientific Abstracts; mRCT and additional sources for published and unpublished trials. The date of the most recent search was 16 September 2008. SELECTION CRITERIA: Randomised controlled trials (RCTs) of vasodilators/vasoactive substance versus placebo in the treatment of ISSHL. Trials were assessed for methodological quality. DATA COLLECTION AND ANALYSIS: The authors assessed trials and extracted data independently. We contacted investigators to obtain additional information where necessary. Meta-analysis was neither possible nor considered appropriate due to the differences in the type of vasodilators used, dosage and duration of treatment. The quality and the result of each study was analysed and reported individually. MAIN RESULTS: Only three trials, involving 189 participants, satisfied the inclusion criteria and these were of low methodological quality. One study showed a significant difference in hearing recovery in the vasodilator group (carbogen combined with a course of several other drugs) compared to the control group (a course of several other drugs alone). Another study only showed a significant improvement in higher frequencies in the vasodilator group (prostaglandin E1 + steroid) compared with the control group (placebo and steroid), no difference having been shown in overall hearing gain. In the third study the vasodilator group (naftidrofuryl and low-molecular weight dextran) showed an improvement only in lower frequencies over the control group (placebo and low-molecular weight dextran).Two of the studies reported adverse effects from vasodilator treatment, whereas there was no mention of any side effects in the third. Five patients in one study developed a sensation of heaviness in the head which settled spontaneously and did not interfere with treatment. In the other study one patient developed an allergic reaction and had to be excluded from the study. AUTHORS' CONCLUSIONS: The effectiveness of vasodilators in the treatment of ISSHL remains unproven. The included studies were of relatively poor quality and the number of patients included was small. Moreover, there were differences in the type, dosage and duration of vasodilator used in each study. Due to the degree of heterogeneity the results could not be combined to reach a conclusion.

RESUMEN

OBJECTIVE: General Practitioners (GPs) are required to diagnose a number of common ear pathologies on a regular basis. In particular, otitis media with effusion (OME) can be well managed in primary care if a reliable diagnosis can be made. We set out to assess the confidence and ability of GPs to diagnose otopathology, as well as the access that they had to tympanometry and pneumatic otoscopy to assist in making their diagnoses. METHODS: Twenty GPs were shown a series of forty slides, half with OME and half with normal tympanic membranes; they were then asked to state whether each image represented an ear with OME or not. The same GPs were then shown 20 slides, half of which were ears with a common pathology and half were normal; the participants were asked to state whether the slide was of a normal ear or make a diagnosis of the pathology. Access to equipment and previous training were assessed via a short questionnaire. RESULTS: The median score for the correct diagnosis of OME was 53% (range 30-67.5%), only slightly higher than chance. The participants correctly identified that an ear was abnormal for a mean of 80% of the time (range 65-95%), but were only able to make a correct diagnosis of the pathology for a mean of 41% of the ears (range 20-80%). No participant had access to pneumatic otoscopy or tympanometry in their practices. CONCLUSIONS: GPs have difficulty in correctly diagnosing OME from otoscopy alone, but are able to determine the presence of other otopathology. They were less able to diagnose specific abnormalities.

RESUMEN

BACKGROUND: Information leaflets are commonly used in Speech and Language Therapy Departments. Despite widespread use, they can be of variable quality. AIMS: To revise current departmental leaflets using the National Health Service (NHS) Toolkit for Producing Patient Information and to test the effect that this has on the readability scores of the text. METHODS & PROCEDURES: Twenty existing leaflets were revised with the help of the NHS Toolkit for Producing Patient Information. Readability statistics were calculated for each leaflet before and after revision. OUTCOMES & RESULTS: The mean Flesch Reading Ease (FRE) score and the Flesch-Kincaid Reading Grade Level (FKRGL) were significantly better in the revised leaflets (p<0.01 and <0.01, respectively). The variability of readability outcome measures was lower in the revised group. Only 25% of the original leaflets met recommended levels of readability, while 75% of the revised leaflets met these standards. CONCLUSIONS: Readability is a vital component to consider in the production of information leaflets. Following simple guidelines on the production of leaflets for patients considerably improves their quality.

RESUMEN

BACKGROUND: An analysis of the scope of practice of recent Otolaryngology - Head and Neck Surgery (OHNS) graduates working as general otolaryngologists has not been previously performed. As Canadian OHNS residency programs implement competency-based training strategies, this data may be used to align residency curricula with the clinical and surgical practice of recent graduates. METHODS: Ontario billing data were used to identify the most common diagnostic and procedure codes used by general otolaryngologists issued a billing number between 2006 and 2012. The codes were categorized by OHNS subspecialty. Practitioners with a narrow range of procedure codes or a high rate of complex procedure codes, were deemed subspecialists and therefore excluded. RESULTS: There were 108 recent graduates in a general practice identified. The most common diagnostic codes assigned to consultation billings were categorized as 'otology' (42%), 'general otolaryngology' (35%), 'rhinology' (17%) and 'head and neck' (4%). The most common procedure codes were categorized as 'general otolaryngology' (45%), 'otology' (23%), 'head and neck' (13%) and 'rhinology' (9%). The top 5 procedures were nasolaryngoscopy, ear microdebridement, myringotomy with insertion of ventilation tube, tonsillectomy, and turbinate reduction. Although otology encompassed a large proportion of procedures billed, tympanoplasty and mastoidectomy were surprisingly uncommon. CONCLUSION: This is the first study to analyze the nature of the clinical and surgical cases managed by recent OHNS graduates. The findings demonstrated a prominent representation of 'otology', 'general' and 'rhinology' based consultation diagnoses and procedures. The data derived from the study needs to be considered as residency curricula are modified to satisfy competency-based requirements.

RESUMEN

Importance: Catastrophizing is a maladaptive thought process that involves irrational fear and worry about anticipated or actual symptoms. Although clinically relevant, the role of catastrophizing in patients with chronic dizziness or imbalance has not yet been explored to our knowledge. Objectives: To validate a measure of dizziness catastrophizing and to assess its association with dizziness-related disability compared with other negative affect constructs (eg, anxiety and depression). Design, Setting, and Participants: For this retrospective medical record review, the Dizziness Catastrophizing Scale (DCS), a dizziness-specific catastrophizing assessment tool, was adapted from the previously validated Pain Catastrophizing Scale. Psychometric evaluation of the DCS was performed. In addition, the associations of dizziness catastrophizing and positive and negative affectivity with dizziness-related disability were assessed using structural equation modeling and regression analyses. Data were collected using a retrospective medical record review from April 27, 2010, to June 25, 2014. The dates of analysis were June 3 to August 15, 2017. The setting was the Multidisciplinary Neurotology Clinic at the Toronto General Hospital (Toronto, Ontario, Canada). Participants were 457 adult outpatients with dizziness or imbalance who were referred to the clinic. Main Outcomes and Measures: Psychometric properties of the DCS and its association with dizziness-related disability, as measured with the Dizziness Handicap Inventory. Results: Among 457 patients (mean [SD] age, 53.4 [15.4] years; 154 [33.7%] male), the DCS demonstrated good convergent (r = 0.78, P < .001) and discriminant validity (r = -0.40, P < .001) with the negative and positive affectivity, respectively; internal consistency (α = .95); and test-retest reliability (intraclass correlation coefficient, 0.92; P < .001 at the 95% CI). An exploratory dimension reduction analysis revealed a single latent component of the DCS. The results of the structural equation modeling and regression analyses revealed that dizziness catastrophizing, although associated with negative affectivity (eg, symptoms of anxiety and depression), was independently associated with dizziness-related disability (standardized ß = 0.378; P < .001). Furthermore, a strong association was found between catastrophizing and dizziness-related disability across different dizziness-related diagnoses (r ≥ 0.6; P < .001). Conclusions and Relevance: In this study, the DCS was a valid and reliable measure for evaluating catastrophic thinking in patients with dizziness, which was independently associated with dizziness-related disability. Future studies should investigate the influence of alleviating symptoms of catastrophizing on functional outcomes in patients with dizziness or imbalance, the results of which will help guide novel approaches to the clinical care of patients with chronic dizziness.

RESUMEN

Impaired insight into illness (IMP-INS) is common among individuals with schizophrenia spectrum disorders (SSD), contributing to medication nonadherence and poor clinical outcomes. Caloric vestibular simulation (CVS) is typically used to assess peripheral vestibular system function. Left cold CVS is also a transiently effective treatment for IMP-INS and hemineglect secondary to right brain hemisphere stroke, and possibly for IMP-INS and mood stabilization in patients with SSD. Participants with SSD and moderate-to-severe IMP-INS participated in an exploratory double blind, crossover, randomized controlled study of the effects of CVS on IMP-INS. Participants sequentially received all experimental conditions-left cold (4°C), right cold, and body temperature/sham CVS-in a random order. Repeated measures ANOVA were performed to compare changes in IMP-INS, mood and positive symptom severity pre and 30min post CVS. A significant interaction was found between CVS condition, time, and body temperature nystagmus peak slow phase velocity (PSPV) for IMP-INS, indicating that single session left cold CVS transiently improved IMP-INS while right cold CVS may have worsened IMP-INS, particularly in participants with greater vestibular reactivity (i.e. higher PSPV) to body temperature CVS. The procedure's effectiveness is attributed to stimulation of underactive right hemisphere circuits via vestibular nuclei projections to the contralateral hemisphere.

RESUMEN

OBJECTIVES: 'Choose and Book' is a UK government initiative devised to allow a greater freedom of choice for National Health Service patients. The system is designed to give patients a choice of hospitals and appointment times, as well as giving their general practitioner (GP) more responsibility for appropriate prioritization. We set out to determine the attitudes of UK GPs to the new Choose and Book project and to assess the impact that these changes are likely to have on ENT practice. DESIGN: Postal questionnaire survey. METHODS: Five hundred GPs were sent a questionnaire about the planned Choose and Book referral project. RESULTS: Three hundred and eighty GPs (76 per cent) replied to the questionnaire after reminders were sent. Most were aware of the project and had been sent information about it. Of those who had heard of it, 61.5 per cent did not think it was a good thing. Most stated that both they and their patients were satisfied with current prioritization practices. Many GPs would be willing to delegate responsibility for prioritization to non-clinical staff. Important time and responsibility issues were identified. CONCLUSIONS: The majority of GPs were not in favour of Choose and Book. Many cited difficulties with time constraints and an inflexible system as factors that made Choose and Book unacceptable.

RESUMEN

The use of suction drains following thyroid and parathyroid surgery is controversial. Although there have been several prospective and retrospective studies carried out on this subject, no paper had sufficient power to provide a suitable answer to whether or not drains should be used routinely. We present the first formal meta-analysis of the data from eight randomized controlled trials on this subject. The result of the meta-analysis showed that there is no difference in complication rates between patients in whom drains have been used routinely and those in whom they have not.

RESUMEN

OBJECTIVES: To determine the levels of intra- and inter-grade variability of the vetting of general practice (GP) letters as well as the intra-rater reliability of letter prioritization. DESIGN: Prospective assessment of letter vetting and questionnaire survey. SETTING: Three otolaryngology secondary referral centres in Bristol and Bath, UK. PARTICIPANTS: Twelve consultants, nine registrars, four staff and associate specialists (SAS) and 16 senior house officers (SHOs) in otolaryngology. METHODS: Fifty GP letters (not including 'fast-track' referrals) addressed to one of the ENT departments were chosen sequentially. These were anonymized, photocopied and included in the questionnaire to all participating staff. Participants were asked to vet the letters as 'urgent', 'soon' or 'routine' according to supplied waiting time criteria. The same letters were sent out again six weeks later. RESULTS: There was no significant difference between grades for the mean number of letters vetted into each category. Intra-grade variability was high; the number of letters vetted urgent varied from one out of 50 to 15 out of 50 for the consultants. The intra-rater reliability was high. CONCLUSION: The grade of trainee seems to make little difference with regard to ability to prioritize referrals, but within grades there is little agreement on what constitutes an urgent referral. We suggest further research, looking at the final outcome of patients, needs to be done to try to establish evidence-based guidelines to assist with letter vetting.

RESUMEN

Epistaxis is a common problem. Most patients presenting to hospital will stop bleeding with simple first-aid measures or with nasal packing. Those who do not stop will usually require surgical management. For persistent posterior epistaxis, the sphenopalatine artery may be ligated as the artery leaves the sphenopalatine foramen to enter the nasal mucosa of the lateral wall of the nose. This may be performed endoscopically. We describe the anatomy of the area and the surgical technique. We also present a brief review of the literature on this technique.

RESUMEN

OBJECTIVE: To evaluate the evidence and trends in published literature on the treatment of Ménière's syndrome or disease (MS/D) by comparing studies published in the last two decades. DATA SOURCES: A literature search was performed on AMED, EMBASE, HMIC, MEDLINE, PsycINFO, BNI, CINAHL, HEALTH BUSINESS ELITE, CENTRAL and Cochrane Ear, Nose and Throat disorders groups trials register using a combination of MeSH. The date of last search was October 2014. STUDY SELECTION AND DATA EXTRACTION: Two hundred five studies (104 in decade I and 101 in decade II) were evaluated to report trends in the management of this condition, the differing levels of evidence published for each treatment modality, evaluate whether the guidelines published by the AAOHNS-Committee on Hearing and Equilibrium had been correctly employed, and whether the randomized controlled trials (RCTs) were compliant with the CONSORT guidelines. RESULTS: The number of published RCTs almost tripled from decade I (1994-2003) to decade II (2004-2103). There was a significant decline in the use of surgical intervention (p = 0.013); however, the number of studies involving the use of intratympanic injection remained largely unchanged. There was a shift in the level of evidence in published studies; studies with level 1 evidence tripled from decade I to II (4.8 to 17.8%, respectively) (p = 0.03); however, compliance with the AAOHNS-CHE criteria for reporting treatment outcomes and the CONSORT checklist was still poor. CONCLUSION: Although the evidence base on published literature on MS/D has improved over the last decade with an increase in emphasis on RCTs and quality of life (QoL) studies, a significant number of studies failed to follow AAOHNS-CHE criteria for reporting treatment outcome and the CONSORT criteria for reporting RCTs.

RESUMEN

OBJECTIVES/HYPOTHESIS: An analysis of the frequency and intensity of postoperative aftercare required for modified radical mastoidectomy (MRM) and patterns of healing in the postoperative period. STUDY DESIGN: A retrospective review of all primary modified radical mastoidectomies carried out for cholesteatoma under the care of the senior author between the years of 2004 and 2009 with minimum follow-up of 2 years. METHODS: The time and number of interventions required to achieve a stable and dry mastoid cavity were collected. Cross-sectional and longitudinal analysis of the behavior of the cavities was carried out. RESULTS: Overall, 73 cases (71 patients) were identified. Patients were followed up for a median of 45.7 months (interquartile range, 31.8-70.5). After initial debridement, most cavities settled rapidly, but this was not always predictable, with a large proportion requiring further clinical intervention after the cavity was stable, sometimes for prolonged periods of time. At the time of analysis, 73% had achieved a stable cavity, 17 (23%) still required attention (nine for wax removal and eight for debridement); two were lost to follow-up. No revision surgeries were required. At 6 months, 36% of cavities were settled, 42% at 1 year, 53% at 18 months, and 62% at 2 years. After two standard postoperative visits, a total of 632 visits were made by these patients. CONCLUSIONS: Following MRM, the majority of patients achieve a dry, self-cleaning mastoid cavity. This might require periods of intense care interspersed with periods of quiescence. These results allow the benefits of this procedure to be put in the context of the entire patient journey.

RESUMEN

OBJECTIVE: Conventional computed tomography (CT) imaging is the standard imaging technique for temporal bone diseases, whereas cone-beam CT (CBCT) imaging is a very fast imaging tool with a significant less radiation dose compared with conventional CT. We hypothesize that a system for intraoperative cone-beam CT provides comparable image quality to diagnostic CT for identifying temporal bone anatomical landmarks in cadaveric specimens. STUDY DESIGN: Cross-sectional study. SETTING: University tertiary care facility. SUBJECTS AND METHODS: Twenty cadaveric temporal bones were affixed into a head phantom and scanned with both a prototype cone-beam CT C-arm and multislice helical CT. Imaging performance was evaluated by 3 otologic surgeons and 1 head and neck radiologist. Participants were presented images in a randomized order and completed landmark identification questionnaires covering 21 structures. RESULTS: CBCT and multislice CT have comparable performance in identifying temporal structures. Three otologic surgeons indicated that CBCT provided statistically equivalent performance for 19 of 21 landmarks, with CBCT superior to CT for the chorda tympani and inferior for the crura of the stapes. Subgroup analysis showed that CBCT performed superiorly for temporal bone structures compared with CT. The radiologist rated CBCT and CT as statistically equivalent for 18 of 21 landmarks, with CT superior to CBCT for the crura of stapes, chorda tympani, and sigmoid sinus. CONCLUSION: CBCT provides comparable image quality to conventional CT for temporal bone anatomical sites in cadaveric specimens. Clinical applications of low-dose CBCT imaging in surgical planning, intraoperative guidance, and postoperative assessment are promising but require further investigation.
