RESUMEN
OBJECTIVE: The main objective of this pediatric study of otologic surgery was to analyze factors for success of outpatient management. The secondary objective was to study unscheduled postoperative consultations and readmissions. MATERIALS AND METHODS: This retrospective observational study analyzed clinical characteristics and procedures in consecutive children undergoing major ear surgery over a 3-year period in a teaching hospital. The study followed STROBE recommendations. RESULTS: We included 214 day-cases from a total population of 271 children. Median age was 109±44months (9years) [range: 8-196months (16years)]. In 57% of cases, the procedure was performed without mastoidectomy: 84 myringoplasties and 37 tympanoplasties. In 43% of cases, mastoidectomy was associated: 47 cochlear implants and 46 closed tympanoplasties for cholesteatoma. Ninety-five percent of day-surgeries were successful; in 5%, there was crossover to pediatric ENT department admission, for the following symptoms: postoperative nausea and vomiting in 3 cases, pain in 3, and late awakening in 5. Univariate analysis showed a relationship between failure and age under 36months (P=0.002). There were no readmissions. There were unscheduled consultations in 3% of cases: for minor otorrhagia in 5 cases and uncomplicated otorrhea in 2. CONCLUSION: Major otologic surgery in children is compatible with day-surgery. Younger patients, usually candidates for cochlear implantation, had greater risk of crossover to conventional admission. In this age group, scheduling should be earlier in the morning, with rigorous postoperative nausea and vomiting prophylaxis.

Acquiring surgical experience in the operating room is increasingly difficult. Simulation of temporal bone drilling is therefore essential, and more and more widely used. The aim of this review is to clarify the limitations of classical surgical training, and to describe the different types of simulation available for temporal bone drilling. Systematic Medline search used the terms: "temporal bone" and training and surgery; "temporal bone" and training and drilling. Seventy-one of the 467 articles identified were relevant for this review. Various temporal bone simulators have been created to get around the limitations (ethical, financial, cultural, working time) of temporal bone drilling. They can be classified as cadaver, animal, physical or virtual models. The main advantages of physical and virtual prototyping are their ease of access, the possibility of repeating gestures on a standardised model, and the absence of ethical issues. Validation is essential before these simulators can be included in the curriculum, to ensure efficacy and thus improve patient safety in the operating room.

OBJECTIVE: Perception of emotion plays a major role in social interaction. Studies have shown that hearing loss and aging degrade emotional recognition. The main aim of the present study was to evaluate the benefit of first-time hearing aids (HA) for emotional prosody perception in presbycusis patients. Secondary objectives comprised comparison with normal-hearing subjects, and assessment of the impact of demographic and audiologic factors. METHODS: To assess HA impact, 29 subjects with presbycusis were included. They were tested without HA and 1 month after starting to use HA. A test with emotional hearing stimuli (Montreal Affective Voice test: MAV) was performed at various intensities (50, 65 and 80dB SPL). Patients' experience was evaluated on the Profile of Emotional Competence questionnaire, before and after HA fitting. Results were compared with those of 29 normal-hearing subjects. RESULTS: Auditory rehabilitation did not significantly improve MAV results (P>0.005), or subjective questionnaire results (P>0.005). Scores remained lower than those of normal-hearing subjects (P<0.001). MAV results, before and after HA, showed significant correlation with pure-tone average (r=-0.88, P<0.001) and age (r=0.44, P=0.018). The older the presbycusis patient and the more severe the hearing loss, the greater the difficulty in recognising emotional prosody. CONCLUSION: Despite hearing rehabilitation, presbycusis patients' results remained poorer than in normal-hearing subjects.

OBJECTIVE: Compared to canal wall up (CWU) tympanoplasty, canal wall reconstruction (CWR) allows better visualization of cholesteatoma extension. The canal wall up approach provides good functional outcomes, but with higher rates of residual cholesteatoma. The aim of this study was to compare residual cholesteatoma prevalence and location between the two approaches. METHOD: Subjects were adult patients with residual cholesteatoma following CWU or CWR surgery between January 1, 2010 and December 31, 2015. During this period, 94 patients underwent CWU and 71 CWR; 22 presented with residual cholesteatoma: 16 after CWU (R-CWU group) and 6 after CWR (R-CWR group). RESULTS: There was no significant inter-group difference in residual cholesteatoma prevalence: 17% after CWU, 8.4% after CWR. Locations comprised: 13 (81%) in the attic, 9 (56%) in the tympanic cavity and 4 (25%) in the mastoid in the R-CWU group, and 6 (100%) in the attic in the R-CWR group. There were significantly fewer tympanic cavity locations after CWR compared to CWU (P=0.046). CONCLUSION: Residual cholesteatoma prevalence did not significantly differ between the CWU and CWR approaches. The most frequent location was the attic; significantly more locations were in the tympanic cavity with the CWU approach. These findings are important for surgeons and neuro-radiologists during follow-up.

INTRODUCTION: General practitioners (GPs) play an essential role in the management of ear disease, but their diagnosis of pathologic eardrums is inadequate. The aim of this study was to compare the quality of otoscopic diagnosis by GPs using a conventional otoscope versus a video-otoscope. Subjects and method Eleven GPs included 124 patients with ear complaints (193 otoscopies). Examination successively used conventional otoscopy and video-otoscopy. After each type of examination, a 10-criterion assessment questionnaire was filled out and a diagnosis was proposed. Two blinded ENT specialists reviewed the video-otoscopy images and filled out the same grid questionnaire to make their diagnosis. GPs also completed a Likert-scale satisfaction questionnaire on video-otoscopy. RESULTS: There were no significant differences in overall examination results between the three groups (GP conventional otoscopy, GP video-otoscopy and ENT specialist). However, focusing exclusively on pathologic eardrums, there was a significant difference in results between ENT specialists and GPs using a conventional otoscope (P=0.0032); this was not the case when GPs used video-otoscopy (P=0.0754). All GPs expressed enthusiastic interest in video-otoscopy, even when not convinced to make the purchase. CONCLUSION: Video-otoscopy showed superiority over conventional otoscopy in assessing pathological eardrums.

Hearing loss can impair auditory discrimination, especially in noisy environments, requiring greater listening effort, which can impact socio-occupational life. To assess the impact of hearing loss in noisy environments, clinicians may use subjective or objective methods. Subjective methods, such as speech audiometry in noise, are used in clinical practice to assess reported discomfort. Objective methods, such as cortical auditory evoked potentials (CAEPs), are mainly used in research. Subjective methods mainly comprise speech audiometry in noise, in which the signal-to-noise ratio can be varied so as to determine the individual speech recognition threshold, with and without hearing rehabilitation, the aim being to highlight any improvement in auditory performance. Frequency discrimination analysis is also possible. Objective methods assess auditory discrimination without the patient's active participation. One technique used for patients with auditory rehabilitation is the study of auditory responses by CAEPs. This electrophysiological examination studies cortical auditory rehabilitation oddball paradigms, enabling wave recordings such as mismatch negativity, P300 or N400, and analysis of neurophysiological markers according to auditory performance. The present article reviews all these methods, in order to better understand and evaluate the impact of hearing loss in everyday life.

OBJECTIVE: Hearing loss subsequent to a unilateral vestibular schwannoma (VS) has an impact on the social life of non-operated patients. We investigated the utility of auditory brainstem responses (ABRs) for predicting the results of auditory rehabilitation in such patients. DESIGN: Prospective study. SETTING: University tertiary medical centre. PARTICIPANTS: We collected the demographic, audiometric, ABR and imaging data of non-operated patients with unilateral VS. A hearing aid trial was performed over 1 month. We assessed auditory performance following the auditory rehabilitation according to the ABR results. Patients with distinct waves (I, III and V) were included in the "distinct ABR" group and patients with no ABR were included in the "desynchronised ABR" group. MAIN OUTCOME MEASURES: Following the trial, audiometric performance and quality of life were evaluated with the Glasgow Benefit Inventory (GBI). SUBJECTS AND METHOD: We collected the demographic, audiometric, ABR and imaging data of non-operated patients with unilateral VS. A hearing aid trial was performed over 1 month. Following the trial, audiometric performance and quality of life were evaluated with the Glasgow Benefit Inventory (GBI). We assessed auditory performance following the auditory rehabilitation according to the ABR results. Patients with distinct waves (I, III and V) were included in the "distinct ABR" group and patients with no ABR were included in the "desynchronised ABR" group. RESULTS: In total, 25 patients were included in this prospective study; 15 in the "distinct ABR" group and 10 in the "desynchronised ABR" group. The speech recognition threshold (SRT, P < .0001; W = -120) and speech discrimination score (P = .0005; W = 78) were significantly improved in the aided vs unaided conditions. These improvements were not observed in the "desynchronised ABR" group for the SRT (P = .48; W = -10) and word recognition score (P = .06; W = 15). Ninety-three per cent of the patients in the "distinct ABR" group kept significantly (P = .04) the hearing aids following the trial compared to 20% in the "desynchronised ABR" group. CONCLUSIONS: Auditory brainstem responses can help to predict the auditory performance following auditory rehabilitation in unilateral non-operated VS patients.
RESUMEN
INTRODUCTION: Temporal bone fractures are frequently associated with ossicular dislocations or fractures, most commonly involving the incus. To our knowledge, isolated fracture of the posterior crus of the stapes has not been previously reported. CASE REPORT: A 20-year-old man consulted for persistent left hypoacusis several months after a head injury. Initial computed tomography of the temporal bone showed a simple temporal bone fracture with no other associated abnormalities. The diagnosis of stapes fracture was suggested by increased compliance on tympanometry, leading to a second thin-section temporal bone computed tomography, which suggested a fracture of the posterior crus of the stapes. Endaural surgical exploration confirmed the diagnosis and allowed placement of ionomer cement in the posterior crus. DISCUSSION: The possibility of ossicular dislocation or fracture must be considered in patients with persistent conductive hearing loss associated with increased compliance on tympanometry, even when computed tomography of the temporal bone does not show dislocation of the ossicular chain or ossicular fracture. Hearing rehabilitation can be performed by hearing aid or surgical reconstruction of the ossicles.

OBJECTIVES: Dissection of cadaveric temporal bones (TBs) is considered the gold standard for surgical training in otology. For many reasons, access to the anatomical laboratory and cadaveric TBs is difficult for some facilities. The aim of this prospective and comparative study was to evaluate the usefulness of a physical TB prototype for drilling training in residency. DESIGN: Prospective study. SETTING: Tertiary referral centre. PARTICIPANTS: Thirty-four residents were included. Seventeen residents (mean age 26.7±1.6) drilled on only cadaveric TBs ("traditional" group), in the traditional training method, while seventeen residents (mean age 26.5±1.7) drilled first on a prototype and then on a cadaveric TB ("prototype" group). MAIN OUTCOME MEASURES: Drilling performance was assessed using a validated scale. Residents completed a mastoid image before and after each drilling to enable evaluation of mental representations of the mastoidectomy. RESULTS: No differences were observed between the groups with respect to age, drilling experience and level of residency. Regarding drilling performance, we found a significant difference across the groups, with a better score in the prototype group (P=.0007). For mental representation, the score was statistically improved (P=.0003) after drilling in both groups, suggesting that TB drilling improves the mental representation of the mastoidectomy whether prototype or cadaveric TB is used. CONCLUSION: The TB prototype improves the drilling performance and mental representation of the mastoidectomy in the young resident population. A drilling simulation with virtual or physical systems seems to be a beneficial tool to improve TB drilling.
