- Abstract
Dysphonia has been described in patients affected by coronavirus disease 2019 (COVID-19). The aim of this study was to evaluate the prevalence of dysphonia, and its severity and extent, of voice fatigue and of dysphagia in non hospitalized patients affected by COVID-19 in Lombardy, the Italian region most hit by the first explosive outbreak of COVID-19 in Europe. Demographic and clinical data of 160 consecutive patients, with COVID-19 diagnosis confirmed by nasal swabs processed by reverse transcription polymerase chain reaction, were gathered by means of telephone interviews performed by physicians in charge of daily follow-up. General and specific symptoms concerning voice and swallowing impairment were investigated. Dysphonia grade and duration were graded on 4-point scales, while voice fatigue was graded on a 5-point scale. Dysphonia was reported by 70 (43.7%) patients and was positively associated with voice fatigue (P < 0.001), cough (P = 0.005), rhinitis (P = 0.01), and dyspnea (P = 0.06); it was mild and/or moderate in 69 patients, but its duration was > 2 weeks in 33/70 (47.1%) patients and >1 month in 11/70 (15.7%). Grade and duration of dysphonia were positively associated with cough and rhinitis (all P values < 0.01). Voice fatigue was reported by 43/160 patients (26.8%) and its severity was correlated with dysphonia (P < 0.0001), cough (P = 0.02), rhinitis (P = 0.02), dyspnea (P < 0.001), and loss of appetite (P = 0.01). Dysphagia was encountered in 27/160 patients (16.9%) and was associated with dysgeusia, cough, arthralgia, myalgia and loss of appetite but not with dysphonia. Dysphonia was a highly prevalent and long-lasting symptom in this series; it has been underestimated to date. Further studies might shed light on the pathophysiology of voice disorders in COVID-19 patients. [ABSTRACT FROM AUTHOR]

Objective: Many studies over the last decade showed favorable outcomes with intratympanic (IT) steroid treatment, alone as salvage treatment or in combination with conventional systemic therapy (ST). However, in severe to profound sensorineural hearing loss resistant to ST, the optimal infusion mode, the type and concentration of the solution, the preferable drug, its total amount, and the duration and fractionation of the treatment are still debated. Aim of the study was to investigate the feasibility and the outcomes of a direct and constant IT delivery of dexamethasone (DEX) by means of a new indwelling catheter.Methods: A prospective case-control study in a tertiary referral university hospital. Ninety-nine subjects treated with ST only and 28 with additional IT DEX have been included in the study. A 4 Fr catheter inserted in a sub-annular fashion with a minimal postero-inferior tympanotomy through and endocanalar approach under local anesthesia. DEX 4mg/ml delivered daily, up to 7 days. Daily bone and air-conducted pure tone and speech audiometry were performed with a follow-up at 1, 3, 6 months after treatment.Results: Twenty-one out of 28 patients (75%) refractory to ST gained on average 24.0dB±20.5dB HL after IT-DEX, compared to 35.4% (average 6.7dB±16.6dB HL) of those receiving only medical ST (p<0.001). No significant side effects were noted.Conclusion: In severe to profound sudden deafness refractory to conventional ST, the daily perfusion of 4mg/ml DEX through an intratympanic catheter is an easy, well accepted procedure that enables patients to receive a drug in the middle ear in a repeatable or sustained form, with minimal discomfort and a partial rescue (67.86%) and a speech recognition gain of 39%.

- Abstract
We report the case of an adolescent with post-verbal severe/profound sensorineural hearing loss, occurring as a consequence of two bouts of pneumococcal meningitis at 12 and 32 months of age. A possible immunodeficiency was investigated, revealing hereditary complement C2 deficiency (C2D). Given the insufficient benefit from high-power hearing aids, the boy received a cochlear implant (CI) at age 12. Despite the long interval of partial hearing deprivation and the post-meningitic etiology, improvement in open-set speech perception and quality of life were observed. The C2D did not favour post-operative infections nor meningitis recurrence. The risks and benefit of CI in this peculiar clinical circumstance are discussed after reviewing the literature.

Abstract: Objectives: To report of a 65-year-old woman with bilateral Meniere''s disease was referred for cochlear implantation (CI) due to severe/profound sensorineural hearing loss. Methods: During the assessment workup, a vestibular schwannoma in the right ear was found by MR imaging. She underwent a translabyrinthine removal of the acoustic neuroma (AN) with sparing of the cochlear nerve and concurrent ipsilateral CI with a Nucleus Freedom device (Cochlear Ltd., Lane Cove, New South Wales, Australia). Results: Complete removal of the AN was achieved without complications. Neural Response Telemetry (NRT) measurements, which showed poor morphology at the intraoperative tests, rapidly improved after activation, similarly to electrically evoked auditory brainstem responses (E-ABR). The patient reached 100% speech perception performances within 2 months from implantation, in the monaural condition. She was relieved from vertigo spell up to 14 months after the operation. Conclusion: Cochlear implantation at the time of acoustic neuroma removal with VIII nerve sparing can be a safe and effective hearing restoration procedure. [Copyright &y& Elsevier]

Summary: Objective: To review the clinical charts of 45 paediatric patients treated for acute otomastoiditis at the ORL Department of the University of Brescia (Italy) between January 1994 and March 2005 and to discuss the diagnostic workup and the outcome of treatment. Methods: Twenty-six males and 19 females were admitted with acute mastoiditis and subperiosteal abscess. Thirteen of them (28.9%) presented an intracranial complication. Only three of them were not operated upon; one received a ventilation tube (VT); all the others underwent a mastoidectomy within 48–72h. Twenty out of 32 uncomplicated mastoiditis were treated conservatively and the remaining 12 underwent myringotomy±VT, associated with a mastoidectomy in 9 cases. Results: Antibiotics alone or with VTs achieved a full recovery in 28 out of 32 uncomplicated cases. Mastoidectomy resolved the disease in 13 patients (9 with complications). In severe complications, a canal wall down (CWD) (n =2) or an intact canal wall (ICW) mastoidectomy (n =7) were preferred, based on the extent of the lesions and the degree of hearing loss. All children recovered completely at 1 year follow-up. In the uncomplicated cases that were operated upon, the mean hospital stay was 7.8 days (versus 4.3 days for the conservative group). In children with intracranial complications the mean hospital stay was 12.8 days, significantly less than the four non-surgical patients, who remained hospitalized for an average of 18 days. Conclusion: Acute mastoiditis can fully recover with conservative treatment or myringotomy+VTs. Immediate surgical treatment is indicated for intracranial complications, if the neurological conditions are not critical. A simple mastoidectomy±tympanoplasty is warranted in: (1) exteriorization, if the child is older than 30 months or >15kg of weight, (2) intracranial complications (combined with a neurosurgical procedure as needed) and (3) cholesteatoma or granulation tissue.

ACOUSTIC reflex ,EAR ossicles ,MIDDLE ear ,INNER ear ,TINNITUS ,MUSCLE contraction - Abstract
Two tiny muscles are attached to the ossicles of the middle ear: the stapedius, whose role as a protector of the inner ear against loud noise has been widely accepted, and the tensor tympani, which remains a mystery since no valid method of detecting its contraction has yet been developed. However, tonic contraction of the tensor tympani has been associated with a number of otological conditions including fullness, tinnitus, slight hearing loss, and Menière-like findings. Our hypothesis is that an easily recognizable sign in the acoustic immittance testing that is part of almost every basic audiological evaluation indicates the contraction of the tensor tympani. During acoustic reflex assessment, a loud stimulus causes a bilateral contraction of the stapedial muscles and an increase in impedance which appears as a deflection in the tracing of the immittance test results. In the case of a contracted tensor tympani, when an intense sound is sent to provoke the acoustic reflex, the stapedius must overcome its resistance which would otherwise have the opposite effect on the footplate. This effort can be seen as a small peak or "preshoot" preceding the greater negative deflection of the impedance. We report the cases of ten patients with unilateral aural symptoms such as tinnitus, impaired noise tolerance, fullness, ear pressure and/or ear discomfort during chewing; the preshoot was present only in the symptomatic ear. If further studies confirm our hypothesis, this could give rise to new therapeutical strategies aimed at reducing contraction of the tensor tympani and balancing its function. [ABSTRACT FROM AUTHOR]

MAGNETIC resonance imaging , *ANATOMICAL planes - Abstract
Background and Purpose: A detailed knowledge of the normal Magnetic Resonance (MR) anatomy of the vestibular endolymphatic space (ES) could be useful to understand the linkage between endolymphatic hydrops (EH) and Ménière's disease (MD). Our aim was to describe the MR anatomy of the vestibular ES as depicted by MR imaging in healthy ears.Methods: This report describes a single-center retrospective study. Three readers analyzed the healthy ears of 22 consecutive patients who had undergone MRI for unilateral sudden hearing loss. The readers described the vestibular ES based on a delayed post-contrast 3D-FLAIR sequence according to six well-defined planes, three oblique sagittal (lateral, intermediate and medial) planes and three axial (superior, intermediate and inferior) planes.Results: On sagittal lateral and intermediate planes, we identified the SSC ampulla combined with the utricle in 22/22 ears. On the sagittal medial plane, the saccule was detectable in 15/22 (68%) ears, having a club shape with the long axis oriented cranio-caudally; in 7/22 (32%) ears, the saccule presented an oval/round shape that appeared more conspicuously on the axial intermediate plane. The ES occupied the half superior portion of the vestibule in 22/22 ears, never contacting the round and oval windows. On the axial plane, in 17/22 cases, the ES showed a Y-shaped arrangement, while in 5/22 ears (23%), the ES presented a more globular shape.Conclusion: MR imaging represents a valid tool to explore the in vivo anatomy of the vestibular ES and to highlight its variability in normal ears.

Objective: We compared the image quality and radiation dose of flat-panel CT (FPCT) and multi-slice CT (MSCT) performed respectively with an angiographic unit and a 128-slice CT scanner. We investigated whether the higher spatial resolution of FPCT translated into higher image quality and we sought to eliminate inter-subject variability by scanning temporal bone specimens with both techniques.Materials and Methods: Fifteen temporal bone specimens were imaged with FPCT and MSCT. Two neuroradiologists experienced in otoradiology evaluated 30 anatomical structures with a 0-2 score; 18 structures important from a clinical perspective were assigned a twofold value in calculation of the overall score. The radiation dose was calculated through the use of an anthropomorphic phantom.Results: The image quality was significantly higher for FPCT than MSCT for 10 of the 30 anatomical structures; the overall score was also significantly higher for FPCT (p = 0.001). The equivalent dose of the two techniques was very similar, but with different effective doses to the organs.Conclusion: FPCT performed on an angiographic unit provides higher image quality in temporal bone assessment compared to MSCT performed on a 128-slice CT scanner thanks to its higher spatial resolution, with comparable equivalent doses but different effective doses to the organs.

Abstract: Pontine tegmental cap dysplasia (PTCD) is an exceptionally rare brain stem and cerebellar malformation characterized by ventral pontine hypoplasia, vaulted pontine tegmentum, hypoplasia of the vermis, subtotal absence of middle cerebellar peduncles, lateralized course of the superior cerebellar peduncles, and absence or alteration of the inferior olivary nucleus. The main clinical features are multiple cranial neurophaties and ataxia. Sensorineural hearing loss of varying severity is almost always present. To date, 14 cases of PTCD have been reported in the literature. We present a child with PTCD and profound bilateral sensorineural hearing loss who underwent cochlear implantation. To the best of our knowledge, cochlear implantation in PTCD has not been previously reported. Functional outcome was assessed using the Speech Perception Categories and the Speech Intelligibility Rating scale. At 22 months’ postoperative evaluation, the patient who was placed into speech perception category 0 (no detection of speech) preoperatively progressed to category 3 (beginning word identification). Before implantation, the child had connected speech unintelligible. At the last follow-up, she had connected speech intelligible to a listener who has little experience of a deaf person''s speech. Cochlear implantation allowed this child to improve her quality of life, increasing her self-confidence, independence, and social integration. [Copyright &y& Elsevier]
