RESUMEN
INTRODUCTION: Patulous Eustachian tube (PET) is a condition affecting approximately 0.3% to 6.6% of the population, with autophony being the predominant complain. The management of PET lacks a well-defined standard in the literature as no effective medical treatments have been documented but various surgical options are available. This study aims to report mid-term outcomes following surgical management of PET. MATERIALS AND METHODS: All patients who underwent surgical intervention for PET between September 2017 and June 2022 were enrolled. Data encompassing general demographics, quality of life (GBI), and procedure-specific data were collected. RESULTS: A total of 30 PET cases (in 19 patients) underwent surgical intervention including 9 injections of hyaluronic acid, 13 fat injections, 6 endoscopic shim insertions, 1 cartilage graft, and 1 injection of hydroxy apatite. After an average follow-up of 22 ± 14 months, 16 cases (53%) achieved complete symptom relief, while 8 cases (26.6%) reported partial relief. Additionally, 11(36%) cases required multiple surgeries. No specific surgical technique demonstrated superiority. Quality of life improved in 77% of cases based on 10 out of 13 GBI collected. Recurrence of PET symptoms occurred on average 10.6 ± 9.7 months after initial surgery, with an estimated global risk of 75% at 3 years. Transient serous otitis media was observed in only 4 cases (13.3%). CONCLUSION: Surgical intervention for PET was found to be effective, achieving complete symptom relief in 53% of cases and significantly improving quality of life 2 years post-surgery. However, a substantial portion of cases necessitated one or more re-interventions. The durability of effectiveness appears to diminish over time.

BACKGROUND: Post-COVID-19 Olfactory impairment has a negative impact on quality of life. The Sniffin Sticks test 12 items (SST-12) can be used in quick olfactory disorders screening. Its evaluation in a post-covid-19 situation was the main objective of this work. METHODS: All patient impaired with a post-COVID olfactory loss were included while consulting to the ENT department. The clinical examination included an olfaction recovery self-assessment (VAS), a nasofibroscopy, a quality of life (QoL) assessment, the complete Sniffin' Sticks Test (SST), and the SST-12. RESULTS: Among the 54 patients included, 92% (n = 50) were correctly screened as olfactory impaired by SST-12. We report excellent correlations between SST-12 and SST (rho (52) = 0.98, p < 0.001), QoL(rho(52) = 0.33 p = 0.016), or VAS (rho(52) = 0.49, p < 0.001) assessments. CONCLUSIONS: SST-12 is a quick and reliable tool to screen large-scale population of post-COVID-19 olfactory impaired patients and could be used in a general daily clinical practice.

ABSTRACT: Aibar-Almazán, A, Martínez-Amat, A, Cruz-Díaz, D, Jesús de la Torre-Cruz, M, Jiménez-García, JD, Zagalaz-Anula, N, Redecillas-Peiró, MT, Mendoza-Ladrón de Guevara, N, and Hita-Contreras, F. The influence of Pilates exercises on body composition, muscle strength, and gait speed in community-dwelling older women: a randomized controlled trial. J Strength Cond Res 36(8): 2298-2305, 2022-Population aging is a global phenomenon that has wide-ranging consequences for the health of individuals, including age-related obesity, muscle loss, and a decline in muscle strength and gait speed. These alterations are associated with disability, functional decline, and mortality in older adults. The objective of this study was to analyze the effects of Pilates exercises on body composition, handgrip strength, and physical performance among community-dwelling Spanish women aged 60 and older. A randomized controlled trial of a 12-week Pilates training program was conducted. A total of 109 women were randomly allocated to either a control ( n = 54) or a Pilates ( n = 55) group. Body composition was evaluated by bioelectrical impedance. Body mass index (BMI), percentage of body fat, and height-adjusted skeletal muscle mass index (SMI) were assessed before and immediately after the intervention, as were physical performance, estimated by gait speed (timed up-and-go test), and handgrip strength. Statistically significant improvements ( p < 0.05) were observed both within and between groups for handgrip strength (Cohen's d = 0.40 and 0.52 respectively) and gait speed (Cohen's d = 0.86 and 0.87 respectively). After 12 weeks, BMI significantly decreased (Cohen's d = 0.07) only in the Pilates group. No significant differences were observed regarding SMI. In conclusion, a 12-week Pilates exercise intervention on community dwelling women over 60 years old shows beneficial effects on muscle strength, physical performance, and BMI, but failed to induce any changes on body composition.

The aim of this study was to assess the validity of ultrasound carried out within seven days prior to birth at term for the calculation of full term estimated foetal weight (EFW) in order to diagnose extreme foetal weight, performed using a single-center retrospective cohort study of 2500 pregnant women. Ultrasound calculations of EFW with a standard error of less than 10% showed an accuracy ratio of 75.1% for the total sample. This percentage was similar for appropriate for gestational age (78.6%) and normal foetal weights (77.5%) but decreased significantly (p < .01) in the case of extreme foetal weights. The simple error increased in both the high and low EFWs, taking on positive values for the low weights and negative values for the high weights. As for the percentage error values, there was a tendency for positive errors for low weights and negative errors for high weights; this led to a tendency to overestimate low foetal weights and underestimate high foetal weights.IMPACT STATEMENTWhat is already known on this subject? Two-dimensional ultrasound is currently the principal tool used in obstetrics to evaluate foetal growth, mainly through the calculation of EFW. Foetal weight represents an important prognostic factor in perinatal results, with a greater risk of adverse effects in cases of extreme foetal weights. In this sense, there are few studies that assess the validity of EFW calculations focussing on extreme foetal weights to term.What do the results of this study add? The ultrasound estimates of EFW with an error lower than 10% in the seven days prior to birth showed an accuracy ratio of 75.1% for the total sample. This percentage was similar to appropriate for gestational age weights (78.6%) and of normal weights (77.5%), but decreased significantly (p < .01) in the case of extreme foetal weights: small for gestational age (52.1%), large for gestational age (68.2%), microsomia (49.1%), and macrosomia (61%). Likewise, we found high specificity and low sensitivity for ultrasound diagnosis of extreme foetal weights.What are the implications of these findings for clinical practice and/or future research? The validity of ultrasound EFW is influenced by extreme foetal weights, with a tendency to overestimate low weights and underestimate high weights, which represents a clinically important finding.

RESEARCH QUESTION: The semen harbours a diverse range of microorganisms. The origin of the seminal microbes, however, has not yet been established. Do testicular spermatozoa harbour microbes and could they potentially contribute to the seminal microbiome composition? DESIGN: The study included 24 samples, comprising a total of 307 testicular maturing spermatozoa. A high-throughput sequencing method targeting V3 and V4 regions of 16S rRNA gene was applied. A series of negative controls together with stringent in-silico decontamination methods were analysed. RESULTS: Between 50 and 70% of all the detected bacterial reads accounted for contamination in the testicular sperm samples. After stringent decontamination, Blautia (Pâ¯=â¯0.04), Cellulosibacter (Pâ¯=â¯0.02), Clostridium XIVa (Pâ¯=â¯0.01), Clostridium XIVb (Pâ¯=â¯0.04), Clostridium XVIII (Pâ¯=â¯0.02), Collinsella (Pâ¯=â¯0.005), Prevotella (Pâ¯=â¯0.04), Prolixibacter (Pâ¯=â¯0.02), Robinsoniella (Pâ¯=â¯0.04), and Wandonia (Pâ¯=â¯0.04) genera demonstrated statistically significant abundance among immature spermatozoa. CONCLUSIONS: Our results indicate that the human testicle harbours potential bacterial signature, though in a low-biomass, and could contribute to the seminal microbiome composition. Further, applying stringent decontamination methods is crucial for analysing microbiome in low-biomass site.

OBJECTIVE: To study knowledge regarding genitourinary syndrome of menopause (GSM) and the treatments for it and to analyze treatment adherence during the COVID-19 confinement. METHODS: Multi-center observational study including women between 35 and 75 years. An extension study of treatment adherence was conducted during the coronavirus pandemic between March and April 2020. RESULTS: A sample of 2355 women were included. Vaginal dryness was the most frequently identified symptom (74.3%). Lubricants were the best-known treatments (69.6%), followed by local estrogens (25.7%); 66% of the women did not speak to their gynecologist about sexuality. Comparative analyses were conducted according to age, menopausal status, type of menopause, place of residence, type of health care received and level of education. During the coronavirus confinement period, adherence to treatments for vulvovaginal atrophy was poor in 72.5% asked (n = 204). Reduced sexual activity (p > 0.001) and coronavirus diagnosis (p = 0.003) were significantly associated with poorer treatment compliance. CONCLUSIONS: There is great lack of knowledge of the treatments used for GSM. Most women do not talk to their gynecologist about sexuality. Adherence to treatments during the coronavirus confinement has been worryingly low.

Objective: This study evaluated the outcomes of the Oticon Medical Neuro Zti cochlear implant and the Neuro 2 sound processor.Design: Neuro One users were upgraded to Neuro 2. Monosyllabic word identification was evaluated in adults with Neuro One after ≥5 months, with Neuro 2 at upgrade, and with Neuro 2 after 3 months. Self-reported listening ability, satisfaction, and usability were measured in adults and children.Study sample: Participants were 44 adults and 26 children.Results: Speech identification scores in quiet and noise were 58% and 45% with Neuro One and 67% and 55% with Neuro 2 after 3 months, respectively. Hearing impairment duration and number of active electrodes significantly predicted speech identification in noise with Neuro 2. Significantly higher questionnaire ratings were obtained for Neuro 2 than Neuro One regarding listening ability in complex listening situations, comfort and music, as well as nine aspects of satisfaction and usability.Conclusion: This study demonstrates the clinical superiority of the Neuro 2 sound processor over Neuro One in terms of speech identification in quiet and in noise and reported patient benefit and satisfaction. Given the study design, sources of improvement may include factors unrelated to the sound processor itself.

INTRODUCTION: Resections of cutaneous tumors in the medial orbitonasal region can be transfixing. Repairs using a single local flap run the risk of failure and that of secondary sinonasal fistula, especially in cases of surgery on a radiated field. We propose an original and reliable repair procedure using two pedicled regional flaps vascularized by two distinct arterial systems clinched together to reconstruct the mucosal and cutaneous planes. MATERIALS AND METHODS: A first melolabial propeller flap (MPF) with a superior perforating pedicle was elevated and the cutaneous side was sutured to the deep plane of the loss of substance (mucosal lining). A second homolateral or contralateral paramedian forehead flap (PFF) was then lifted and sutured over the first flap (superficial plane). The forehead pedicle flap was divided at 1 month. RESULTS: No trophic complication or failure was recorded on two patients. The 7-year carcinologic, aesthetic, and functional results were satisfying. CONCLUSION: This technique involving the superimposition of two local flaps, vascularized by two different arterial systems, appears to offer a simple and reliable repair technique for transfixing cutaneous losses of substance in the medial orbitonasal region. It could be used in the first-line treatment, particularly if an additional radiotherapy is to be performed.

BACKGROUND: Presbycusis has a direct influence on autonomy of the elderly but hearing aids lack of affordability. Moreover a recent review demonstrate that electroacoustic characteristics of OTC hearing aids were generally not suitable for the elderly people. In our study, we assessed the clinical value of a new over-the-counter (OTC) hearing aid device (TEO First®) in the elderly. METHOD: This prospective monocentric open label study included patients over 60 years of age with a mild to moderate presbycusis. Patients were assessed with acceptable noise level test (ANL), pure tone (PTA) and speech (SA) audiometry in silent and noisy environment, with and without TEO First®. A Glasgow Hearing Aid Benefit Profile, acceptability and satisfaction surveys were completed after one month of using the device. RESULTS: Thirty one patients were included. There was an improvement of hearing with TEO First® in silence (SA: +39.2 %, p < 0.01; PTA: -9.04 dB, p < 0.01) or in noise (SA +47.7 %, p < 0.01; PTA: -5.23 dB, p < 0.05). After one month of use of the device, quality of life has improved with regards to the following parameters: decrease of perceived hearing difficulties during conversation without background noise (-9.6 % p = 0.018), in conversation with several people (-16.2 % p = 0.0076), decrease of negative emotions while watching TV (-18.5 % p = 0.011), during conversation without background noise (-16.5 % p = 0.0024), during conversation in noisy background (-17.1 % p = 0.027) and during conversation with several people (-20 % p = 0.014). The acceptability of the device was low to moderate. CONCLUSION: TEO First® is an effective OTC hearing aid that improves the patient's quality of life. TRIAL REGISTRATION: Current Controlled Trials NCT01815788.

The goal of this study was to evaluate, in the hands of an inexperienced surgeon, the cochleostomy location of an endaural approach (MINV) compared to the conventional posterior tympanotomy (MPT) approach. Since 2010, we use in the ENT department of Nice a new surgical endaural approach to perform cochlear implantation. In the hands of an inexperienced surgeon, the position of the cochleostomy has not yet been studied in detail for this technique. This is a prospective study of 24 human heads. Straight electrode arrays were implanted by an inexperienced surgeon: on one side using MPT and on the other side using MINV. The cochleostomies were all antero-inferior, but they were performed through an endaural approach with the MINV or a posterior tympanotomy approach with the MPT. The positioning of the cochleostomies into the scala tympani was evaluated by microdissection. Cochleostomies performed through the endaural approach were well placed into the scala tympani more frequently than those performed through the posterior tympanotomy approach (87.5 and 16.7 %, respectively, p ≤ 0.001). This study highlights the biggest challenge for an inexperienced surgeon to achieve a reliable cochleostomy through a posterior tympanotomy, which requires years of experience. In case of an uncomfortable view through a posterior tympanotomy, an inexperienced surgeon might be able to successfully perform a cochleostomy through an endaural (combined approach) or an extended round window approach in order to avoid opening the scala vestibuli.

Technological advances in the domain of digital signal processing adapted to cochlear implants (CI) are partially responsible for the ever-improving outcomes observed with this neural prosthesis. The goal of the present study was to evaluate audiometric outcomes with a new signal processing strategy implemented in Oticon Medical-Neurelec cochlear implant systems, the xDP strategy. The core of this approach is a preset-based back-end output compression system, modulating a multi-channel transfer function depending on the intensity and information content of input sounds. Twenty adult CI patients, matched for age and CI experience, were included in this study. Pure-tone thresholds and vocal audiometry scores were measured with their former signal processing strategy and with xDP. Speech perception was assessed using dissyllabic words presented in quiet, at different intensity levels: 40, 55, 70, and 85 dB SPL, and in a cocktail party noise at a signal-to-noise ratio of +10 dB. Results with the xDP strategy showed, as awaited, no major modification of pure-tone thresholds. A global increase of speech perception scores was observed after a 1-month habituation period, with significant improvements for speech perception in quiet for moderate (55 dB SPL), loud speech sounds (85 dB SPL), and speech-in-noise comprehension. Subjective signal quality assessment showed a preference for Crystalis(xDP) over the former strategy. These results allow the quantification of improvements provided by the xDP signal processing strategy.

OBJECTIVE: The aim of this study was to evaluate the potential improvements of speech perception and sound quality provided by a multiband single channel noise-reduction algorithm based on the modified Wiener-filter adapted to cochlear implant sound processing. DESIGN: This study was a longitudinal trial with a repeated-measures design. Outcome measures were performed on the first day when the noise reduction feature was provided and after a one month habituation period. Objective measures included pure-tone thresholds and vocal audiometry assessments. Speech perception was measured in quiet and in the presence of two types of noise: a stationary speech shaped noise and a two-talker cocktail noise. Subjective sound quality was assessed using a ten item questionnaire. STUDY SAMPLE: Thirteen post-lingual deaf adults, experienced users of a cochlear implant system, took part in this study. RESULTS: The noise-reduction algorithm provided a benefit for the perception of speech presented in a stationary speech shaped noise and an overall improvement in subjective sound quality ratings. CONCLUSIONS: It was shown that a single channel noise reduction system based on a modified Wiener-filter approach can improve speech in noise perception performance and subjective sound quality in cochlear implant patients.

The aim of this study was to assess dose attenuation by a Digisonic SP cochlear implant (CI) and evaluate its impact on treatment planning. The Digisonic CI was irradiated with 6 MV photons. Overall dose attenuation was assessed with MOSFET dosimeters and Gafchromic films. In addition, we evaluated the attenuation of separate CI components. Dose attenuation was also calculated using different radiation treatment planning systems (TPS) softwares and dose calculation algorithms. The CI was placed on a head phantom. Single-beam and multiple-beam plans were evaluated for dose attenuation using two radiation techniques (Conformal and Stereotactic radiotherapy) and four different algorithms (Clarkson, Point Kernel-Superposition, Ray Tracing and Monte Carlo). MOSFET and Gafchromics film showed maximal 6-7.5% radiation dose attenuation, at the center of the CI. Computerized TPS-based dose attenuation by the implant was 4-8.1%, using a single ipsilateral field. No clinically meaningful dose attenuation was found in multiple field plans owing to the contribution of various beam paths with only a couple going through the implant using either conventional conformal or stereotactic treatment plans. Dose attenuation induced by a Digisonic SP CI is about 6%, for single 6 MV photon field. This dose reduction is unlikely to be clinically significant, as single-field radiotherapy plans to this anatomic region are uncommon.

OBJECTIVE: To evaluate taste disorders after middle ear surgery, their modifying factors especially chorda tympani nerve injury or underlying otologic disease. We investigated consequences of taste disorders on quality of life. STUDY DESIGN: Prospective cohort study. SETTING: Monocentric study in tertiary care center. METHODS: A total of 214 patients who underwent middle ear surgery were included. Data regarding taste disorders were collected by questionnaires over a 1-year follow-up period. RESULTS: Taste disorders were reported in 42.7% at 10 days, in 23.3% at 4 months, and in 9.2% 1 year postoperatively. When the chorda tympani nerve was initially healthy, taste disorders were more frequent after its transection throughout the follow-up period. When it was involved in a cholesteatoma or inflammatory process, postoperative taste disorders were more frequent after nerve stretching. Postoperative discomfort in daily life was rated on the Likert scale at 3.5 out of 10. Dietary modifications were reported by 25.8% of patients, and mood alterations by 15% of patients. CONCLUSION: Taste disorders are frequent after middle ear surgery although they mostly improve in the first months. When the CTN is healthy, cutting it leads to more taste disorders than stretching it, thus advocating its preservation to prevent these symptoms. However, in cases of pathological CTN, cutting this nerve, which is sometimes necessary to control the disease, is less likely to cause taste disorders than stretching it. These taste disorders are a source of discomfort and may present risks of dietary modifications and emotional impact.
RESUMEN
Over the past decade, the adoption of universal hearing screening in newborns has led to earlier detection of hearing problems and significant lowering of the age of first cochlear implantation. As a consequence, recipients are now expected to keep their cochlear implants (CIs) for a longer period of time. Comprehensive longitudinal information on CI reliability is essential for device choice. The aim of this study was to assess the reliability (in children and adults) of the latest generation of the Digisonic(®) SP CI launched in 2006 by Neurelec. Failure rate (FR) and cumulative survival rate (CSR) for a 5-year period were calculated. This survey is a multicenter retrospective study. A questionnaire was sent to nine CI centers requesting information about patients implanted with Neurelec Digisonic(®) SP CIs. FR and CSR over a 5-year period were calculated on this group. Collaborating centers collected data on 672 patients (362 children and 310 adults) implanted between March 2006 and March 2011. The overall rate of explantation was 2.23 % (15 cases): six devices were explanted due to device failure (0.89 %) and nine were explanted for medical reasons (1.34 %). Four patients were lost to follow-up. The CSR at 5 years was 98.51 % on all patients, 98.48 % for children and 98.57 % for adults. FR was 0.97 % for adults and 0.83 % for children. This first independent study that assesses FR and CSR on the current generation of Digisonic(®) SP CI represents an important resource that can help clinicians and patients during their device choice.

The present study investigates how electrically evoked Auditory Brainstem Responses (eABRs) can be used to measure local channel interactions along cochlear implant (CI) electrode arrays. eABRs were recorded from 16 experienced CI patients in response to electrical pulse trains delivered using three stimulation configurations: (1) single electrode stimulations (E11 or E13); (2) simultaneous stimulation from two electrodes separated by one (En and En+2, E11 and E13); and (3) stimulations from three consecutive electrodes (E11, E12, and E13). Stimulation level was kept constant at 70% electrical dynamic range (EDR) on the two flanking electrodes (E11 and E13) and was varied from 0 to 100% EDR on the middle electrode (E12). We hypothesized that increasing the middle electrode stimulation level would cause increasing local electrical interactions, reflected in characteristics of the evoked compound eABR. Results show that group averaged eABR wave III and V latency and amplitude were reduced when stimulation level at the middle electrode was increased, in particular when stimulation level on E12 reached 40, 70, and 100% EDR. Compound eABRs can provide a detailed individual quantification of electrical interactions occurring at specific electrodes along the CI electrode array. This approach allows a fine determination of interactions at the single electrode level potentially informing audiological decisions regarding mapping of CI systems.
RESUMEN
Hearing loss is a major public health problem with significant evidence correlating it with cognitive performance. Verbal fluency tests are commonly used to assess lexical access. They provide a great deal of information about a subject's cognitive function. The aim of our study was to evaluate phonemic and semantic lexical access abilities in adults with bilateral severe to profound hearing loss and then to re-evaluate a cohort after cochlear implantation. 103 adult subjects underwent phonemic and semantic fluency tests during a cochlear implant candidacy evaluation. Of the total 103 subjects, 43 subjects underwent the same tests at 3 months post-implantation. Our results showed superior performance in phonemic fluency compared to semantic fluency in subjects prior to implantation. Phonemic fluency was positively correlated with semantic fluency. Similarly, individuals with congenital deafness had better semantic lexical access than individuals with acquired deafness. Results at 3 months post-implantation showed an improvement in phonemic fluency. No correlation was found between the evolution of pre- and post-implant fluency and the auditory gain of the cochlear implant, and we found no significant difference between congenital and acquired deafness. Our study shows an improvement in global cognitive function after cochlear implantation without differentiation of the phonemic-semantic pathway.
RESUMEN
Understanding cochlear anatomy is crucial for developing less traumatic electrode arrays and insertion guidance for cochlear implantation. The human cochlea shows considerable variability in size and morphology. This study analyses 1000+ clinical temporal bone CT images using a web-based image analysis tool. Cochlear size and shape parameters were obtained to determine population statistics and perform regression and correlation analysis. The analysis revealed that cochlear morphology follows Gaussian distribution, while cochlear dimensions A and B are not well-correlated to each other. Additionally, dimension B is more correlated to duct lengths, the wrapping factor and volume than dimension A. The scala tympani size varies considerably among the population, with the size generally decreasing along insertion depth with dimensional jumps through the trajectory. The mean scala tympani radius was 0.32 mm near the 720° insertion angle. Inter-individual variability was four times that of intra-individual variation. On average, the dimensions of both ears are similar. However, statistically significant differences in clinical dimensions were observed between ears of the same patient, suggesting that size and shape are not the same. Harnessing deep learning-based, automated image analysis tools, our results yielded important insights into cochlear morphology and implant development, helping to reduce insertion trauma and preserving residual hearing.
RESUMEN
BACKGROUND: One of the most common complaints among menopausal women concerns changes in sexual function. This is attributed to various factors, including anatomical defects in the genital tract, with pelvic organ prolapse (POP) being one of the most prevalent problems affecting women during this stage of their lives. Additionally, symptoms resulting from gonadal hypofunction can also contribute to the development of sexual dysfunction during menopause. This research aimed to explore the way in which postmenopausal patients with POP experienced their sexuality in our setting. METHODS: To achieve the proposed objective, we conducted a descriptive, cross-sectional study involving a total of 133 postmenopausal women with POP. RESULTS: The results of our series are consistent with the scarce literature available in our setting and suggest a high rate of sexual dysfunction in postmenopausal patients with POP. CONCLUSIONS: We can conclude that POP is associated with the presence of female sexual dysfunction.
