Exclusive endoscopic tympanoplasty efficacy in the treatment of cholesteatoma without mastoid involvement.

PURPOSE: The purpose of this study is to determine the recurrence rate of cholesteatoma in patients who have undergone exclusive endoscopic tympanoplasty at our tertiary referral institution. A secondary objective is to analyze different clinical aspects that could be considered risk factors for recurrence to establish if it is possible to determine when a second-look procedure is indicated instead of a clinical follow-up. METHODS: A retrospective study was performed on patients who had undergone exclusive endoscopic tympanoplasty for cholesteatoma in the last eight years and who were followed up for at least one year. The efficacy of the treatment performed only with the exclusive endoscopic technique was analyzed. Then, the anamnestic and intraoperative data were studied to identify possible factors that could increase the risk of recurrence. RESULTS: The recurrence rate (14.5%) in patients (164) who underwent primary surgery with the exclusive endoscopic technique between January 2014 and January 2022 was similar to that in patients who underwent the microscopic technique with mastoidectomy in literature. In addition, we analyzed several clinical factors such as age, ossicular chain erosion, extension and localization of the cholesteatoma finding that only the last one could potentially be a risk factor for recurrence in this selected population. CONCLUSION: Exclusive endoscopic tympanoplasty has been shown to be effective in removing cholesteatoma in patients without evidence of mastoid involvement, with recurrence rates comparable to traditional microscopic technique and a minimally invasive approach, even considering the patient's age, ossicular chain erosion and extension of the disease.

Updates on Larynx Cancer: Risk Factors and Oncogenesis.

Laryngeal cancer is a very common tumor in the upper aero-digestive tract. Understanding its biological mechanisms has garnered significant interest in recent years. The development of laryngeal squamous cell carcinoma (LSCC) follows a multistep process starting from precursor lesions in the epithelium. Various risk factors have been associated with laryngeal tumors, including smoking, alcohol consumption, opium use, as well as infections with HPV and EBV viruses, among others. Cancer development involves multiple steps, and genetic alterations play a crucial role. Tumor suppressor genes can be inactivated, and proto-oncogenes may become activated through mechanisms like deletions, point mutations, promoter methylation, and gene amplification. Epigenetic modifications, driven by miRNAs, have been proven to contribute to LSCC development. Despite advances in molecular medicine, there are still aspects of laryngeal cancer that remain poorly understood, and the underlying biological mechanisms have not been fully elucidated. In this narrative review, we examined the literature to analyze and summarize the main steps of carcinogenesis and the risk factors associated with laryngeal cancer.

Monoclonal Antibodies Targeting CGRP: A Novel Treatment in Vestibular Migraine.

Background. Monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP) or its receptor represented the first targeted and specialized approach to migraine prophylaxis. Nevertheless, they have been rarely considered in the treatment of vestibular migraine (VM). Our aim was to evaluate the effectiveness of anti-CGRP mAbs in VM patients who did not respond to conventional migraine treatments. Methods. Consecutive VM patients treated with erenumab were considered. As a comparison, we considered the same VM patients during conventional migraine treatments (i.e., propranolol, flunarizine, or valproic acid), which were tried before mAbs therapy. Videonystagmography, the Italian version of the Dizziness Handicap Inventory (DHI) questionnaire, and migraine days over the last 3 months were evaluated in all patients before and after treatments. Results. In the present retrospective study, we included 21 female and 2 male VM patients, mean age 45.2 years. All patients underwent contrast-enhanced magnetic resonance imaging that ruled out other causes of vertigo. The DHI questionnaire significantly improved after mAb therapy (p < 0.0001). Mean migraine days over the last 3 months were significantly reduced after treatment (p = 0.001). Videonystagmography was altered in 11 (48%) patients prior to monoclonal antibodies. We found vertical positional nystagmus in 9 patients and horizontal positional nystagmus in 2 patients. After the treatment, we found vertical positional nystagmus only in 1 patient (p = 0.002). When patients were treated with conventional therapies, there was no significant reduction in DHI, and instrumental vestibular examinations remained altered. Conclusions. VM patients using anti-CGRP mAbs experienced a reduction in the dizziness-derived handicap, as reported in the DHI questionnaire. Furthermore, these treatments were significantly associated with a normalization of vestibular instrumental analysis. These findings were not seen with conventional treatments. Treatment with anti-CGRP mAbs may be effective in VM patients who did not respond to conventional migraine treatments. These findings should be tested in large, randomized clinical trials.

Negative Outcome of Temporalis Fascia Graft in Tympanoplasty with Excessive Bleeding: A Retrospective Study.

Background and Objectives: Non-autologous graft materials hold promise for tympanic membrane (TM) perforation closure. In the present manuscript, we aimed to evaluate the influence of clinical and surgical (i.e., graft materials) characteristics on tympanoplasty outcome in chronic otitis media (COM). Materials and Methods: We retrospectively reviewed clinical and surgical characteristics of COM patients with TM perforation treated with tympanoplasty and mastoidectomy. Univariate and multivariate appropriate tests were applied. Results: We used xenograft (porcine submucosal collagen) in 163 patients, and temporalis fascia in 210. The mean follow-up time was 37.2 months. Postoperative TM perforation (i.e., negative outcome) was detected in 11.6% of cases with xenograft, and in 12.8% with temporalis fascia. Performing uni- and multivariate analysis, we determined that large (three or all quadrants) TM perforation (p = 0.04) and moderate-to-severe intraoperative bleeding (p = 0.03) were independent prognostic factors of negative outcome. Considering the 197 patients with moderate-to-severe intraoperative bleeding, we disclosed that the use of temporalis fascia (p = 0.03) was an independent risk factor of postoperative TM perforation. Conclusions: According to our results, large TM perforation and moderate-to-severe intraoperative bleeding were independent prognostic factors of negative outcome in adult COM patients treated with tympanoplasty. In the sub-group of COM patients with excessive intraoperative bleeding, use of temporalis fascia was associated with negative outcome; these patients could benefit from xenograft materials. These findings should be tested in large randomized clinical trials.

The Role of Primary Mitochondrial Disorders in Hearing Impairment: An Overview.

Background. Defects of mitochondrial DNA (mtDNA) involved in the function of the mitochondrial electron transport chain can result in primary mitochondrial diseases (PMDs). Various features can influence the phenotypes of different PMDs, with relevant consequences on clinical presentation, including the presence of hearing impairment. This paper aims to describe the hearing loss related to different PMDs, and when possible, their phenotype. Methods. A systematic review was performed according to PRISMA guidelines, searching Medline until December 2022. A total of 485 papers were identified, and based on specified criteria, 7 were included in this study. Results. A total of 759 patients affected by PMDs and hearing loss were included. The age of patients ranged from 2 days to 78 years old, and the male-to-female ratio was 1.3:1. The percentage of subjects affected by hearing loss was 40.8%, (310/759), and in most cases, hearing impairment was described as sensorineural, bilateral, symmetrical, and progressive, with different presentations depending on age and syndrome severity. Conclusions. PMDs are challenging conditions with different clinical phenotypes. Hearing loss, especially when bilateral and progressive, may represent a red flag; its association with other systemic disorders (particularly neuromuscular, ocular, and endocrine) should alert clinicians, and confirmation via genetic testing is mandatory nowadays.

The Role of Fibrinogen, Homocysteine and Metabolic Syndrome's Alterations in Sudden Sensorineural Hearing Loss (SSHL): A Narrative Review.

Fibrinogen and homocysteine (HCY) are molecules known to play a role in vascular homeostasis, and their blood levels are often elevated in patients with metabolic syndrome. Recent evidence suggests that sudden sensorineural hearing loss (SSHL) may have a vascular origin. This has led many authors to advocate that fibrinogen, homocysteine, and metabolic syndrome (MetS) may play a direct role in SSHL. The aim of this brief review is to examine the role and influence of these molecules and MetS on the mechanisms of SSHL. Elevated fibrinogen levels have been associated with a worse prognosis in SSHL, possibly due to increased blood viscosity and decreased blood flow. Similarly, HCY has been associated with vascular damage, particularly in hyperhomocysteinemia, although the exact association with SSHL remains controversial. MetS has been demonstrated to function both as a causative factor and as a contributor to poorer recovery in cases of SSHL. However, although some studies suggest a possible role for these biomarkers and MetS in the prognosis and treatment of SSHL, specific therapeutic and preventive strategies based solely on these factors have yet to be developed. Given their potential role in prognosis and treatment and the global epidemic of metabolic syndrome, this issue needs to be analyzed comprehensively. Thus, further quality studies need to be conducted, even though it is difficult to determine the actual impact of MetS on the development of SSHL, as it is a multifactorial disease affecting multiple organs.

Polyphenols in Inner Ear Neurobiology, Health and Disease: From Bench to Clinics.

There is substantial experimental and clinical interest in providing effective ways to both prevent and slow the onset of hearing loss. Auditory hair cells, which occur along the basilar membrane of the cochlea, often lose functionality due to age-related biological alterations, as well as from exposure to high decibel sounds affecting a diminished/damaged auditory sensitivity. Hearing loss is also seen to take place due to neuronal degeneration before or following hair cell destruction/loss. A strategy is necessary to protect hair cells and XIII cranial/auditory nerve cells prior to injury and throughout aging. Within this context, it was proposed that cochlea neural stem cells may be protected from such aging and environmental/noise insults via the ingestion of protective dietary supplements. Of particular importance is that these studies typically display a hormetic-like biphasic dose-response pattern that prevents the occurrence of auditory cell damage induced by various model chemical toxins, such as cisplatin. Likewise, the hormetic dose-response also enhances the occurrence of cochlear neural cell viability, proliferation, and differentiation. These findings are particularly important since they confirmed a strong dose dependency of the significant beneficial effects (which is biphasic), whilst having a low-dose beneficial response, whereas extensive exposures may become ineffective and/or potentially harmful. According to hormesis, phytochemicals including polyphenols exhibit biphasic dose-response effects activating low-dose antioxidant signaling pathways, resulting in the upregulation of vitagenes, a group of genes involved in preserving cellular homeostasis during stressful conditions. Modulation of the vitagene network through polyphenols increases cellular resilience mechanisms, thus impacting neurological disorder pathophysiology. Here, we aimed to explore polyphenols targeting the NF-E2-related factor 2 (Nrf2) pathway to neuroprotective and therapeutic strategies that can potentially reduce oxidative stress and inflammation, thus preventing auditory hair cell and XIII cranial/auditory nerve cell degeneration. Furthermore, we explored techniques to enhance their bioavailability and efficacy.

A case-control study of visually evoked postural responses in childhood with primary headaches.

BACKGROUND: Disorientation, nausea, confusion, dizziness, and displacement are frequently complained by headache-suffering children. Anyhow, the cause of these symptoms is still unclear, and a dysfunction of vestibular pathways or their alteration due to central pain pathways hyper-activation, has been proposed. The aim of this study is to use posturography to explore the balance function of headache-suffering children during pain-free periods. METHODS: Posturography was performed on 19 migraineurs, 11 tension-type headache sufferers, and 20 healthy controls. Posturographic measures were performed during headache-free periods under different conditions: with eyes opened, eyes closed, and during right and left optokinetic stimulation. The last 2 conditions were used to mimic unreliable visual signals that can confound vestibular system. RESULTS: During eyes-closed conditions, headache-suffering children displayed higher displacements than healthy controls, since statokinesiogram surface was higher in tension-type headache sufferers and migraineurs compared with controls (P value = 0.0095). Romberg's index, indicating the overall stability of the subject, was lower in healthy controls than in headache sufferers (P = 0.0139), thus suggesting a vestibular impairment in the seconds. Moreover, both during right and left optokinetic stimulation, the statokinesiogram length was higher in headache-suffering children (P < 0.0001). Thereafter, statokinesiogram surface was higher in migraineurs during right optokinetic stimulation (P = 0.0388) than in tension-type headache sufferers when stimulation was directed on the opposite side (P = 0.0249). CONCLUSIONS: These results suggest a central alteration of vestibular pathways in headache-suffering children, that makes balance function more dependent from visual inputs than healthy subjects, even in inter-ictal phases.

The Atopy Index Inventory: A Brief and Simple Tool to Identify Atopic Patients.

INTRODUCTION: Atopy and ear, nose and throat (ENT) diseases are frequently associated; however, no clinical tool has been proposed so far to discriminate which patients could be atopic and therefore deserving of a further immunoallergological evaluation. OBJECTIVE: The aim of this study was to assess and validate a set of dichotomous responses suitable for predicting the presence of atopy in adult patients. METHODS: An 11-item questionnaire, i.e., the Atopy Index Inventory (AII), comprised of 4 questions regarding the clinical history for allergic disease and 7 questions evaluating the presence of the most frequent clinical signs affecting allergic patients, was developed and administered to 226 adult subjects (124 atopic subjects and 102 healthy, not atopic subjects). The atopic condition was proven by an immunoallergological evaluation according to the diagnostic criteria of the EAACI guidelines. Internal consistency and clinical validity were tested. RESULTS: In healthy subjects, the first 4 variables of the AII returned a 100% correct response (all answered "no") and were defined as "decisive" responses. In the logistic regression analysis, when decisive items were negative, the atopic condition was confirmed when answering "yes" to at least 3 "probability" items (cut-off = 2.69). The difference in AII scores between allergic and healthy group was significant using the Mann-Whitney U test (p < 0.0001). The sensitivity and specificity of the AII were 0.97 and 0.91, respectively, with a true predictive value of 0.92 and a false predictive value of 0.97. The ROC curve showed an area of 0.94, with an OR of 0.88 (95% CI 0.87-0.97, p = 0.0001). The internal consistency as determined by the Cronbach α coefficient was 0.88. CONCLUSION: The AII has been proven to be a brief, simple and sufficiently accurate tool for screening ENT patients in search of atopic individuals and to allow their clinical management.

Acquired Hearing Loss, Anger, and Emotional Distress: The Mediating Role of Perceived Disability.

The aim of the study was to test whether acquired hearing loss (AHL)-related perceived disability mediates the association between AHL and psychological outcomes, including anger. Two-hundred ninety-seven consecutive outpatients with AHL assessed by pure tone average (PTA) loss completed the following: Hearing Handicap Inventory for Adults (HHIA), State-Trait Anger Expression Inventory-2 (STAXI-2), Brief Symptom Inventory (BSI), Diagnostic Criteria for Use in Psychosomatic Research (DCPR), and Social Functioning Questionnaire. In the sample, composed of 44.5% males with a mean age of 53.8 and a mean PTA of 30.7, AHL was associated to perceived hearing handicap, also correlating to all psychological measures except DCPR demoralization. Associations were stronger between the HHIA-Emotional Subscale, STAXI-2 State Anger and Feeling Angry, and BSI-Somatization, Interpersonal Sensitivity, Depression, and Psychoticism. Perceived disability predicted the presence of almost all psychosocial outcomes and confirms to be the most significant target of clinical action.

Gusher in stapes surgery: a systematic review.

OBJECTIVE: The aim of this study is to perform a systematic literature review on the occurrence of gusher during stapes surgery, to understand its surgical management and outcomes. METHODS: The PRISMA standard was applied to identify English, Italian or French-language studies, related to stapes surgery and mentioning gusher or perilymphatic leak. Full-texts lacking information on the management of gusher and/or the post-operative hearing outcome were excluded. RESULTS: Twenty-four articles were eventually included. Seventy-six patients were involved in the qualitative synthesis. The management of gusher mostly consisted in covering the oval window and/or filling the tympanic cavity, with absorbable and autologous graft materials. Packing of the external auditory canal was reported in 51 patients (67%). Gusher was related to complete/profound loss of hearing in 25% of the cases and to a worsening of hearing function in 31% of patients. In 19% of patients an improvement in hearing tests was reported; in 28% the hearing function was unchanged. Post-operative vestibular symptoms were reported in 7 patients, and were mainly mild and transient. The absence of vestibular symptoms was underlined in 9 cases, while in 79% of the patients the authors did not provide information. CONCLUSION: The unexpected occurrence of gusher during stapes surgery represents a relevant issue for the otologic surgeon. Its management most commonly consists in plugging the oval window and the tympanic cavity. In most of the cases, a stapes prosthesis could be positioned. The results on hearing and vestibular functions are widely variable.

Are periodontal outcomes affected by personality patterns? A 18-month follow-up study.

OBJECTIVES: This research aims to study the relationship between personality traits and periodontal clinical outcomes by taking into account the level of anxiety and depression, periodontal health and oral hygiene behaviour of patients affected with gingivitis or moderate periodontitis requiring periodontal therapy. MATERIAL AND METHODS: The periodontal data of 40 systemically healthy patients affected by gingivitis or moderate periodontitis were collected at baseline and 18 months later. The psychological variables, dental awareness and adherence intent of the patients were assessed through questionnaires, and only those patients that exhibited a higher degree of compliance were included in the study. The personality traits (cluster A: paranoid, schizoid, schizotypal; cluster B: borderline, antisocial, narcissistic, and histrionic; cluster C: avoidant, dependent, and obsessive-compulsive) and the level of anxiety and depression of the patients were assessed. Patients were instructed with oral hygiene measures and were treated with periodontal therapy. RESULTS: Clusters A and B showed a consistent tendency for reduced levels of oral hygiene (increased full-mouth plaque score - FMPS). The results from cluster B were found to be significantly related to deep periodontal pockets at baseline. On the contrary, cluster C seemed to be linked to clinically better indices, particularly in terms of full-mouth-bleeding-score and pocket depth, both at baseline and 18 months later. The results collected from clusters B and C were directly correlated with anxiety, depression and FMPS. Moreover, anxiety was directly correlated with the patient's need for professional oral-care. CONCLUSIONS: Personality traits appear to play a significant role in determining the therapeutic outcomes of periodontal therapy in themselves. Thus, it is ideal for several important psychological, affective or behavioural factors to be associated with various personality traits so as to orient the outcome of periodontal therapy.

Vertigo "in the pink": The impact of female gender on psychiatric-psychosomatic comorbidity in benign paroxysmal positional vertigo patients.

BACKGROUND: Comorbidity between vestibular and psychiatric disorders in predisposed individuals is underestimated, untreated, and may result in chronicization and poor quality of life. There are few studies concerning the type and the prevalence of psychiatric-psychosomatic distress in patients with benign paroxysmal positional vertigo (BPPV). OBJECTIVE: The aim of this study was to evaluate psychiatric-psychosomatic comorbidities, in particular anxiety, depression, somatization symptoms, and alexithymia, in a group of BPPV patients compared with healthy subjects, and according to gender. METHODS: Case-control study comparing 92 BPPV patients recruited at the ENT Unit of Modena General Hospital between November 2007 and December 2010, and 141 healthy controls. The Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Diagnostic Criteria for Psychosomatic Research (DCPR), Brief Symptom Inventory (BSI), and Toronto Alexithymia Scale (TAS-20) were used to perform psychometric assessment. RESULTS: BPPV patients scored higher than controls, with statistical significance, at BDI, BSI somatization, anxiety, and phobic anxiety subscales, and STAI state anxiety; a larger proportion of BPPV patients suffered from clinically significant BDI depressive symptomatology; DCPR disease phobia, functional somatic symptoms secondary to a psychiatric disorder, and demoralization were more common among BPPV subjects. High levels of symptomatology were still found among BPPV female patients, but not among males, even after controlling for symptom severity. CONCLUSIONS: Affective symptomatology, such as depression, demoralization, phobia and anxiety, and somatization, were significantly prevalent in BPPV patients, and female gender may be a predisposing factor.

Acute Onset of Peripheral Facial Nerve Palsy in Children: An Overview.

Background The facial nerve (FN) plays a pivotal role in human life; apart from its sensory and parasympathetic functions, it innervates the facial muscles, and it is therefore involved in non-verbal communication, allowing us to express emotions and reactions. Especially in the case of childhood onset, FN dysfunction can severely affect the quality of life. Methods The aim of this review is to analyze the most recent literature, focusing on the acute onset of peripheral FN palsy among pediatric patients, discussing the different etiologies, prognoses, and management strategies. A total of 882 papers were initially identified, but only 7 met the selection criteria. Therefore, data on 974 children in total were pooled and analyzed. Results According to the findings of this review, FN palsy is idiopathic in most cases, while an infective etiology was identified as the second most common. The main pathogen agents identified were Borrelia Burgdorferi, especially in endemic areas, and Herpesviridae. Respiratory tract infections and/or ear infections were also described. Head trauma or direct injury of the FN accounted for 2% of all cases. Conclusions The overall FN recovery rate is high, even though the etiology remains unknown for most patients. Therapeutic indications are still lacking, especially in the case of non-recovering FN palsy. In our opinion, large, prospective studies are necessary for improving our knowledge of this disorder and establishing evidence-based approaches.

Congenital deafness and vestibular disorders: a systematic literature review.

Introduction: Congenital deafness is a pathological entity that represents an economical and social burden, affecting up to 0.2% of newborns in Europe. Sensorineural hearing loss (SHL) is caused by a variety of factors, including congenital abnormalities, perinatal infectious diseases and genetic syndromes. The inner ear's vestibular system, nestled alongside the auditory organs, is crucial for balance maintenance. Its close connection with the auditory system means that disturbances in one often coincide with disturbances in the other, highlighting their intertwined functions. With this review we aim to describe objective vestibular tests found in literature and to study their use for diagnosis of vestibular disturbances in patients affected by congenital deafness. Methods: The review is conducted with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. The search string used was: [(congenital deafness) OR (congenital hearing loss) OR (congenital hypoacusia)] AND [(vestibular disorders) OR (vertigo)]. An initial abstract reading selection was made, and a subsequent comprehensive full-text reading. For each article, we identified the type of vestibular test utilized and its corresponding outcome. Results: Out of the initial-papers identified through the search string-articles met the eligibility criteria for further analysis through abstract and full-text reading. After further selection-articles were chosen for detailed examination, focusing on the data of patients. Conclusion: Congenital hearing loss profoundly affects a child's development, especially in language and communication skills, and it is frequently associated with a pathological vestibular system. Early identification allows timely intervention with personalized therapies. In current literature, there is still no gold standard test to identify balance disorders in patients with congenital hearing loss. There is considerable variability on the subject due to the inclusion of diverse patients with various diagnoses, alongside a wide range of available technologies. Managing such conditions necessitates collaboration among healthcare providers, ensuring comprehensive care through prompt diagnosis and personalized treatment plans. Ongoing research aims to further improve screening methods and develop precision medicine approaches tailored to individual needs.

The role of artificial intelligence in training ENT residents: a survey on ChatGPT, a new method of investigation.

Objective: The primary focus of this study was to analyze the adoption of ChatGPT among Ear, Nose, and Throat (ENT) trainees, encompassing its role in scientific research and personal study. We examined in which year ENT trainees become involved in clinical research and how many scientific investigations they have been engaged in. Methods: An online survey was distributed to ENT residents employed in Italian University Hospitals. Results: Out of 609 Italian ENT trainees, 181 (29.7%) responded to the survey. Among these, 67.4% were familiar with ChatGPT, and 18.9% of them used artificial intelligence as a tool for research and study. In all, 32.6% were not familiar with ChatGPT and its functions. Within our sample, there was an increasing trend of participation by ENT trainees in scientific publications throughout their training. Conclusions: ChatGPT remains relatively unfamiliar and underutilised in Italy, even though it could be a valuable and efficient tool for ENT trainees, providing quick access for study and research through both personal computers and smartphones.

The Efficacy of Wireless Auditory Training in Unilateral Hearing Loss Rehabilitation.

PURPOSE: The purpose of this study was to evaluate the efficacy of auditory training (AT) in patients with unilateral hearing loss (UHL) using hearing aids (HAs), comparing traditional methods with a new approach involving a wireless remote microphone. METHODS: The study included 96 participants, divided into two groups, with ages ranging from 42 to 64 years, comprising both male and female subjects. A clinical trial including consecutive moderate UHL patients was performed at our institution. For the study group, a Roger Pen was used during AT with patients inside a sound-attenuating cabin. Controls followed conventional sessions. Professional speech and language pathologists performed the rehabilitation. Audiological outcomes were measured, including word recognition at signal-to-noise ratios (SNRs) of 0 dB, +5 dB, and +10 dB, to determine the effectiveness of the training. Measurements also included the Speech, Spatial, and Qualities of Hearing Scale to assess perceived auditory abilities. RESULTS: A total of 46 and 50 UHL patients were randomly included in the study and control groups, respectively. No differences were found in terms of sex, age, presence of tinnitus, duration of hearing loss, pure tone average, and speech-in-noise perception without an HA. Following HA fitting and AT, a notable enhancement in the ability to identify speech in noisy environments was observed in the study group. This improvement was significant at SNRs of +5 and +10. When comparing the ability to identify speech in noise using HAs across both groups, it was observed that hearing capabilities post-wireless AT showed a significant improvement at an SNR of +5. Only the study group had a significant improvement in the total Speech, Spatial, and Qualities of Hearing Scale score after the training. CONCLUSIONS: In our group of UHL patients, we found significantly better speech-in-noise perception when HA fitting was followed by wireless AT. Wireless AT may facilitate usage of HAs, leading to binaural hearing in UHL patients. Our findings suggest that future interventions might benefit from incorporating wireless technology in AT programs.

Subtotal Petrosectomy: Pictorial Review of Clinical Indications and Surgical Approach.

Subtotal petrosectomy (STP) is characterized by obliteration of the middle ear and occlusion of the external auditory canal. The advent of the endoscope has allowed a reduction in morbidity for some conditions such as cholesteatoma and other middle ear disorders, but STP still plays an important role. A retrospective review of medical records and videos of patients who had undergone STP was performed. Perioperative data and images were collected from various clinical cases who had undergone subtotal petrosectomy at our tertiary referral university hospital in Verona. We confronted our experience with a review of the literature to present the main indications for this type of procedure. STP allows a variety of diseases to be managed effectively as it offers the possibility of a definitive healing with radical clearance of temporal bone. Moreover, it can be safely combined with other procedures with a very low complication rate. Although the endoscope represents a revolution in ear surgery, STP, when indicated, is nowadays a surgical option that should be included in the otosurgeon's portfolio.

Unilateral Hearing Loss and Auditory Asymmetry in Mitochondrial Disease: A Scoping Review.

Background/Objectives: Mitochondrial transfer RNA mutations are one of the most important causes of hereditary hearing loss in humans. In most cases, its presentation is bilateral and symmetrical; however, there are numerous cases of single-sided presentation or asymmetrical onset described in the literature that may represent a diagnostic challenge. The aim of this review is to present the evidence of auditory asymmetry in mitochondrial diseases, highlighting the possible presence of cases with atypical presentation. Methods: A review of the English literature to date on hearing loss and mitochondrial diseases was performed using PubMed, Scopus, and Google Scholar databases. The literature review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines for scoping review. Results: A total of 10 full-text articles were included in this review, comprising 25 patients with single-sided or asymmetrical hearing loss associated with mitochondrial disease. Conclusions: Sensorineural hearing loss due to mitochondrial disease can represent a complex diagnostic challenge in cases of asymmetric or unilateral presentation. It is critical to recognize this clinical variant and to diagnose it in daily clinical practice.

Communication Skills in Toddlers Exposed to Maternal SARS-CoV-2 during Pregnancy.

Studies about the effects of SARS-CoV-2 on pregnant women and children born to positive women are controversial with regard to possible inner ear-related damage but most of them do not detect the involvement of this virus in auditory function. However, only a few studies on long-term effects on language development are currently available because of the recent onset of the pandemic. The aim of this study was to investigate the impact of SARS-CoV-2 infection on perceptual and expressive abilities and the emerging development of communication in young children. To this purpose, the MacArthur-Bates Communicative Development Inventory-Words and Gestures form (CDI-WG), was administered to parents. In total, 115 children whose mother was infected by SARS-CoV-2 during pregnancy were enrolled in the study and evaluated at the Audiology Service of the Modena University Hospital. All children underwent Otoacoustic Emissions (OAE) at birth: 114/115 had a "pass" result bilaterally, while 1 case had a unilateral "refer" result. Overall, 110/115 newborns (95.65%) underwent audiological evaluation between 10-18 months of age. In 5/110 patients (3.6%), the Pure Tone Average (PTA) result was equal to 35 dB; one case had a hearing threshold of around 50 dB due to a bilateral effusive otitis media. A notable finding was the percentage of children with tubal dysfunction in both evaluations, within 2 months of age and around 12 months of age. Most children revealed normal hearing. The CDI-WG was completed by 56/115 families. The rate of children below the fifth percentile was 8.9% for sentences understood, 12.5% for words understood, and 5.4% for words produced. Concerning CDI-Gestures, only 2 children (3.6%) were below the fifth percentile. A structured audiological follow-up in association with the evaluation of communication skills of children appears fundamental, particularly in the years of maximum neuroplasticity. Long-term studies are still necessary to evaluate the possible consequences of the pandemic.
