This systematic review sheds light on the effectiveness of auditory–verbal therapy (AVT) outcomes in children with cochlear implants (CIs). The presented outcome is based on research findings from the last 10 years. The systematic review was designed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Critical Appraisal of Treatment Evidence (CATE) checklist. Specific keywords were chosen based on the research question and searched on the PubMed database. All searched papers were analysed based on specific exclusion criteria and classified into four evidence levels. The results revealed that children who participated in AV therapy can achieve linguistic skills at the same level as their hearing peers. Voice quality seemed positively affected, placing young children with CIs in the normal range for receptive vocabulary development. In contrast, reading skills seemed less benefited. AV therapy seems to contribute to integration into mainstream society. Despite the recorded speech and language improvements of young children with CIs, the aim of AV therapy is still not fulfilled. AV therapy can be seen as the best clinical practice for young children with CIs till now, but the lack of well-controlled studies is undermining.

Background: Eustachian Tube Dysfunction (ETD) presents significant diagnostic challenges, particularly in patients with chronic nasal disease, which often mimic or complicate ETD symptoms. Tubomanometry (TMM) is emerging as an objective tool for diagnosing ETD, but its application in patients with concurrent nasal pathologies remains underexplored. Methods: One hundred patients with concurrent ETD and chronic nasal disease were recruited. They were categorized into three groups: chronic rhinitis (35 patients, group A), nasal septal deviation (31 patients, group B) and chronic rhinosinusitis with polyps (34 patients, group C). Treatments included nasal irrigation, septoplasty, and nasal polypectomy with functional endoscopic sinus surgery, respectively. The TMM parameters (R, C2 and C2–C1 scores) were assessed before and after interventions. The patient reported outcome measures (ETDQ-7 and NOSE scores) were also recorded and statistically correlated with TMM measures. Results: Group A showed improvements in R, C2 and C2–C1 scores and mild post-treatment reductions in ETDQ-7 and NOSE scores. Similar improvements were observed in Group B, with significant symptom reduction post-septoplasty, particularly on the side of the nasal septal deviation. Group C demonstrated the greatest improvement, with significant improvements in TMM values and substantial reductions in both ETDQ-7 and NOSE scores. The statistical results revealed correlations between the treatment of nasal pathologies and ETDQ-7 and NOSE scores. Conclusions: All TMM parameters improved in each group following the nasal intervention. This study highlights the utility of TMM in evaluating ETD in the context of chronic nasal disease and suggests that treating underlying nasal conditions can significantly alleviate ETD symptoms.

Benign paroxysmal positional vertigo (BPPV) is one of the most common peripheral vestibular dysfunctions encountered in clinical practice. Although the treatment of BPPV is relatively successful, many patients develop recurrence after treatment. Our purpose is to evaluate the mean recurrence rate and risk factors of BPPV after treatment. A review of the literature on the risk factors of BPPV recurrence was performed. A thorough search was conducted using electronic databases, namely Pubmed, CINAHL, Academic Search Complete and Scopus for studies published from 2000 to 2020. Thirty studies were included in this review with 13,358 participants. The recurrence rate of BPPV ranged from 13.7% to 48% for studies with follow-up <1 year, and from 13.3% to 65% for studies with follow-up ≥2 years. Pathophysiologic mechanisms and implication of each of the following risk factors in the recurrence of BPPV were described: advanced age, female gender, Meniere’s disease, trauma, osteopenia or osteoporosis, vitamin D deficiency, diabetes mellitus, hypertension, hyperlipidemia, cardiovascular disease, migraine, bilateral/multicanal BPPV, cervical osteoarthrosis and sleep disorders. Patients with hyperlipidemia and hypertension had the highest recurrence rates of BPPV, 67.80% and 55.89%, respectively, indicating that vascular comorbidities increase the risk of BPPV recurrence. In addition, more than half of patients (53.48%) with diabetes mellitus and BPPV experienced recurrence of BPPV. Knowledge and awareness of risk factors for recurrence of BPPV are essential for the assessment and long-term prognosis of patients. Identification of these relapse risk factors may enhance the ability of clinicians to accurately counsel patients regarding BPPV and associated comorbidities.

Background: To evaluate patients with middle ear cholesteatoma presenting with facial palsy (FP). Material-Methods: A total of 14 subjects (10 males and 4 females), with a mean age of 42.5 years, were included in our study. The majority of patients presented with incomplete FP (House–Brackmann HB II-IV, 11 cases) and the remaining 3 patients had complete facial paralysis (HB V-VI). A canal wall down mastoidectomy was performed in all the patients, followed by partial facial nerve decompression. Results: At the one-year follow-up, eleven (78.5%) patients demonstrated satisfactory recovery to HB I-II. Facial function recovered to HB grade I-II in 9 (100%) patients who were surgically treated within one month, and in 2 (40%) patients who underwent surgery after one month. The tympanic segment of facial nerve was the most common site of involvement (8 patients). The multiple regression analysis showed that a higher preoperative HB grade combined with a gradual than sudden onset of FP more likely resulted in worse postoperative HB grade. Conclusion: Early surgical removal of cholesteatoma associated with FP is more likely to result in good facial nerve recovery (78.5% of cases), when it is performed within one month from the onset of FP. According to the literature, the tympanic segment of the facial nerve was more frequently damaged (77.7%), followed by the mastoid segment (22.9%), labyrinthine segment (11.1%), and geniculate ganglion (11.1%). Labyrinthine fistula, mainly of the lateral semicircular canal, can be expected in cases of facial nerve dehiscence. The canal wall down mastoidectomy combined with partial decompression surgery was the most preferred surgical treatment for the FP secondary to cholesteatoma.

Background/Objectives: Cochlear implants (CIs) constitute a viable method for auditory rehabilitation in patients with profound sensorineural hearing loss after temporal bone fractures (TBFs). These patients comprise a challenging population due to the anatomical deformity and neural injury. Methods: By performing this systematic review, we attempted to evaluate the viability of CIs in the context of TBF. The literature search, across Pubmed/MEDLINE, Scopus and Google Scholar, was performed under the PRISMA guidelines. The selected time period was from December 1995 to September 2025. The final analysis included 11 manuscripts. The majority of the studies were retrospective case series with a moderate risk of bias. Results: The primary outcome was postoperative auditory function, evaluated with speech perception tasks and aided sound-field pure-tone audiometry. The secondary outcomes were the report of radiological and electrophysiologic prognosticators of implants’ viability, timing of surgery, procedural feasibility and complications. Across the studies, CIs conferred meaningful auditory benefit when the cochlear nerve was intact. High-Resolution Computed Tomography (CT) was utilized for TBF classification and cochlear patency, whereas Magnetic Resonance Imaging (MRI) and a promontory test were crucial for the assessment of neural integrity. Prompt placement, optimally within 12 months after trauma, was related to improved outcomes by limiting cochlear fibrosis and ossification. Despite patients’ impedance fluctuation, restricted speech perception in noise and frequent abnormal facial nerve excitation, the overall audiologic and speech discrimination results are comparable to non-trauma recipients. Conclusions: A CI appears to be the choice of treatment over auditory brainstem implants, as long as the cochlear nerve remains intact. Rapid implantation in well-selected patients coupled with ordinal mapping and follow-up can restore dysfunctional hearing and improve patients’ quality of life.

The impact of language input on children’s speech, language, and brain development was borne out of Hart and Risley’s famous “30-million-word gap”. A perspective bolstered by many studies in the last decade relates higher socio-economic status (SES) to better qualitative and quantitative differences in children’s speech. The logic chains found in these studies suggest that literacy development depends on language and brain development. Thus, brain building develops based on environmental experience and language input depends on the brain’s perception of the auditory information. This essay uses the latest published peer-reviewed research to outline the current landscape of the role of SES in the development of speech and language skills among children with hearing loss (HL) who are enrolled in auditory-driven habilitation programs. This essay argues that low SES families may provide sufficient input for their children. The outcome of auditory-driven programs implemented by speech-language pathologists (SLPs) seems to be detached from SES. The role of SES on this developmental trajectory remains unclear, and clinical practice may be related to other validated and robust parameters related to hearing loss.

Purpose The purpose of this prospective, randomized, multicenter clinical trial was to compare the therapeutic efficacy of systemic versus intratympanic versus combined administration of steroids in the treatment of idiopathic sudden sensorineural hearing loss. Methods 102 patients with an up to 14 days history of idiopathic sudden sensorineural hearing loss were randomized to 1 of 3 arms and followed prospectively. Group A (35 patients) received prednisolone intravenously followed by methylprednisolone orally, whereas Group B (34 patients) were administered intratympanic methylprednisolone. Patients in Group C (33 patients) were administered the combination of the above-mentioned treatment modalities. The patients were followed-up with pure tone audiograms on days 1 (initiation of treatment), 3, 5, 10, 30 and 90. Results The final mean hearing gain was 29.0 dB HL for Group A, 27.0 dB HL for Group B and 29.8 dB HL for Group C. The differences between the three groups were not statistically significant. When hearing improvement was assessed according to Siegel’s criteria, no statistically significant difference was recorded either. Furthermore, patients younger than 60 years old achieved significantly better hearing outcomes. Conclusions The results demonstrated that systemic, intratympanic and combined steroid administration have similar results in the primary treatment of idiopathic sudden hearing loss. Younger patients are more likely to achieve better hearing outcomes.

Background: Sudden, non-traumatic hearing loss has been associated with vascular or inflammatory disorders. Hearing loss in Neuromyelitis optica spectrum disorder (NMOSD) is a very rare presentation. Methods: In this paper, we describe the case of a 58-year-old female patient with aquaporin-4-positive NMOSD exhibiting bilateral tinnitus and right-sided deafness in the context of a relapse. The auditory brainstem responses pointed to a lesion of the right peripheral auditory pathway (cochlea and/or auditory nerve). The patient’s hearing failed to improve after high-dose intravenous steroids; however, it showed slight improvement after plasmapheresis. We also conducted a systematic literature review in databases MEDLINE and Scopus in English, searching for all reported cases of hearing loss in NMOSD. Results: We included 10 studies reporting 15 cases of NMOSD with hearing loss. The vast majority of patients were female (11 out of 15, 73.3%), with an age range of 26 to 70 years. Hearing loss, ranging from mild to severe, seems more frequent in AQP4-positive cases, and it can even be the presenting symptom. It can present isolated or in combination with tinnitus, ataxia, and/or intractable vomiting. The auditory pathway impairment in NMOSD seems to be localized either centrally, i.e., cochlear nuclei or higher brainstem levels, or peripherally, i.e., in the cochlea or cochlear nerve itself. Intravenous methylprednisolone in high doses, followed by oral tapering, was the most common treatment option, resulting in a gradual improvement. Conclusions: This paper describes a rare case of peripheral auditory pathway affection in NMOSD, which is an inflammatory astrocytopathy mainly affecting the central nervous system. Early recognition of hearing loss in the context of an NMOSD relapse and subsequent treatment have a crucial impact on the hearing outcome of NMOSD patients. This expands our knowledge of NMOSD as an autoimmune aquaporin-4 channelopathy.

This editorial highlights the limitations of relying solely on pure-tone audiometry for diagnosing and managing hearing loss, particularly in the fields of speech-language pathology and audiology. While pure-tone audiometry has long been the gold standard for assessing hearing sensitivity, its capacity to fully capture the complexities of hearing impairments is increasingly called into question. The article examines the profound impact of hearing loss on language development, psychosocial well-being, and quality of life, especially in infants and toddlers, who are at risk of significant delays in speech and language development. These delays affect various linguistic domains, including morphology, vocabulary, syntax, semantics, and speech intelligibility. Hearing loss often distorts sound perception, particularly of softer consonants and key morphemes critical for understanding verb tenses, possessives, and plurals, further hindering language comprehension and communication. The article critiques traditional training programs for speech-language pathologists (SLPs) and audiologists, which tend to focus on basic pure-tone audiograms and standardized hearing loss classifications. It argues for a more comprehensive educational approach that emphasizes deeper audiogram interpretation, enabling improved diagnosis and management of hearing loss. Additionally, while remaining focused on pure-tone audiometry, the article discusses how SLPs can be better equipped to \"decode\" audiogram data, thereby enhancing early intervention strategies to support optimal language development in young children with hearing loss.
