Abstract
Emergency situations involving the ears, nose, and throat (ENT) area can pose considerable challenges for clinicians and often require an interdisciplinary approach due to the involvement of different organ systems. To avoid damage to highly relevant sensory and perception organs and life-threatening bleeding or respiratory complications, strategies that are as quick and targeted as possible are necessary. This article aims to provide an overview of ENT emergency management strategies. The entire spectrum from simple conservative to highly complex surgical measures plays a role here, both diagnostically and therapeutically. Aspects such as bleeding, respiratory problems, inflammation, hearing disorders, vertigo, facial palsy and injuries to the head and neck area are discussed. In addition, important topics such as preventive measures and possible complications are also addressed to ensure optimal patient care.

Pentoxifylline, dexamethasone and azithromycin demonstrate distinct age-dependent and synergistic inhibition of TLR- and inflammasome-mediated cytokine production in human newborn and adult blood in vitro. PLoS One 2018; 13:e0196352.

Abstract
Introduction Neonatal inflammation, mediated in part through Toll-like receptor (TLR) and inflammasome signaling, contributes to adverse outcomes including organ injury. Pentoxifylline (PTX), a phosphodiesterase inhibitor which potently suppresses cytokine production in newborn cord blood, is a candidate neonatal anti-inflammatory agent. We hypothesized that combinations of PTX with other anti-inflammatory agents, the steroid dexamethasone (DEX) or the macrolide azithromycin (AZI), may exert broader, more profound and/or synergistic anti-inflammatory activity towards neonatal TLR- and inflammasome-mediated cytokine production. Methods Whole newborn and adult blood was treated with PTX (50–200 μM), DEX (10−10–10−7 M), or AZI (2.5–20 μM), alone or combined, and cultured with lipopolysaccharide (LPS) (TLR4 agonist), R848 (TLR7/8 agonist) or LPS/adenosine triphosphate (ATP) (inflammasome induction). Supernatant and intracellular cytokines, signaling molecules and mRNA were measured by multiplex assay, flow cytometry and real-time PCR. Drug interactions were assessed based on Loewe's additivity. Results PTX, DEX and AZI inhibited TLR- and/or inflammasome-mediated cytokine production in newborn and adult blood, whether added before, simultaneously or after TLR stimulation. PTX preferentially inhibited pro-inflammatory cytokines especially TNF. DEX inhibited IL-10 in newborn, and TNF, IL-1β, IL-6 and interferon-α in newborn and adult blood. AZI inhibited R848-induced TNF, IL-1β, IL-6 and IL-10, and LPS-induced IL-1β and IL-10. (PTX+DEX) synergistically decreased LPS- and LPS/ATP-induced TNF, IL-1β, and IL-6, and R848-induced IL-1β and interferon-α, while (PTX+AZI) synergistically decreased induction of TNF, IL-1β, and IL-6. Synergistic inhibition of TNF production by (PTX+DEX) was especially pronounced in newborn vs. adult blood and was accompanied by reduction of TNF mRNA and enhancement of IL10 mRNA. Conclusions Age, agent, and specific drug-drug combinations exert distinct anti-inflammatory effects towards TLR- and/or inflammasome-mediated cytokine production in human newborn blood in vitro. Synergistic combinations of PTX, DEX and AZI may offer benefit for prevention and/or treatment of neonatal inflammatory conditions while potentially limiting drug exposure and toxicity.

Abstract
BACKGROUND High-dose corticosteroids are currently recommended for idiopathic sudden sensorineural hearing loss (ISSNHL) treatment. Intratympanic injections (ITI) are of growing importance, especially in cases of therapy resistance. The selection of patients for this procedure in SSNHL has not been adequately examined so far. STUDY DESIGN A total of 77 patients with ISSNHL after ineffective systemic pretreatment underwent intratympanic administration of dexamethasone and hyaluronic acid. Improvement after treatment was determined by pure tone audiometry for both ears before and of the treated ear after ITI. RESULTS In this study 34 female and 43 male patients with mean age of 57 years showed a pre-ITI hearing loss of 35 dB in the lower frequencies and 69 dB in the higher frequencies. The mean hearing gain was 10 dB and the response rate was 62%. Absolute hearing gain revealed significant improvements at 500 Hz, 1 kHz and 2 kHz. Under inclusion of contralateral thresholds there were hardly any differences up to 4 kHz. In a detailed analysis of responders moderate improvements could be observed even in higher frequencies. Overall, no relevant adverse events occurred. CONCLUSION Treatment of ISSNHL resistant to systemic regimens by ITI of steroids provides an option that offers additional prospects of auditory improvement for affected patients. The presented results indicate that these modalities are also valid for patients with pancochlear ISSNHL.

Disabling vertigo and tinnitus caused by intrameatal compression of the anterior inferior cerebellar artery on the vestibulocochlear nerve: a case report, surgical considerations, and review of the literature. J Neurol Surg Rep 2014; 75:e47-51.

Abstract
Microvascular compression of the vestibulocochlear nerve is known as a cause of tinnitus and vertigo in the literature, but our review of the literature shows that the compression is usually located in the cerebellopontine angle and not intrameatal. We present a case of intrameatal compression of the anterior inferior cerebellar artery (AICA) on the vestibulocochlear nerve of a 40-year-old woman with symptoms of disabling vertigo and intermittent high-frequency tinnitus on the left side without any hearing loss for ∼ 4 years. Magnetic resonance imaging of the brain did not show any abnormality, but magnetic resonance angiography showed a left intrameatal AICA loop as a possible cause of the disabling symptoms. After the exclusion of other possible reasons for disabling vertigo, surgery was indicated. The intraoperative findings proved the radiologic findings. The large AICA loop was found extending into the internal auditory canal and compressing the vestibulocochlear nerve. The AICA loop was mobilized and separated from the vestibulocochlear nerve. The patient's symptoms resolved immediately after surgery, and no symptoms were noted during 2 years of follow-up in our clinic. Her hearing was not affected by the surgery. In addition to other common reasons, such as acoustic neuroma, disabling vertigo and tinnitus can occur from an intrameatal arterial loop compression of the vestibulocochlear nerve and may be treated successfully by drilling the internal acoustic meatus and separating the arterial conflict from the vestibulocochlear nerve.

Prognostic impact of standard laboratory values on outcome in patients with sudden sensorineural hearing loss. BMC EAR, NOSE, AND THROAT DISORDERS 2014; 14:6.

Abstract
Background Aim of the present study was to evaluate prognostic factors, in particular standard laboratory parameters, for better outcome after idiopathic sudden sensorineural hearing loss (SSNHL). Methods Using a retrospective review, 173 patients were included presenting between 2006 and 2009 with unilateral SSNHL, ≥30 dB bone conduction in three succeeding frequencies between 0.125 to 8 kHz in pure tone audiometry (PTA), and a time interval between first symptoms and diagnostics ≤ 4 weeks. Hearing gain of <10 dB versus ≥10 dB in the affected ear in 6PTA values was the primary outcome criterion. Univariate and multivariate statistical tests were used to analyze predictors for better outcome. Results The initial hearing loss was 50.6 ± 27.2 dB. The absolute hearing gain was 15.6 ± 20.1 dB. Eighty-one patients (47%) had a final hearing gain of ≥10 dB. Low-frequency hearing loss (p <0.0001); start of inpatient treatment <4 days after onset (p = 0.018); first SSNHL (versus recurrent SSNHL, p = 0.001); initial hearing loss ≥ 60 dB (p < 0.0001); an initial quick value lower than the reference values (p = 0.040); and a pretherapeutic hyperfibrinogenemia (p = 0.007) were significantly correlated to better outcome (≥10 dB absolute hearing gain). Multivariate analysis revealed that first SSNHL (p = 0.004), start of treatment <4 days after onset (p = 0.015), initial hearing loss ≥ 60 dB (p = 0.001), and hyperfibrinogenemia (p = 0.032) were independent prognostic factors for better hearing recovery. Conclusion Better hearing gain in patients with hyperfibrinogenemia might be explained by the rheological properties of the applied therapy and supports the hypothesis that SSNHL is caused in part by vascular factors.

Abstract
Microvascular compression of the vestibulocochlear nerve is known to cause disabling tinnitus and vertigo. A review of the literature shows that the compression is usually located in the cerebellopontine angle, and that it is usually caused by an artery. The authors add the case of a 46-year-old man with venous compression of the vestibulocochlear nerve inside the internal auditory canal (IAC). The patient presented with a 2-year history of recurrent attacks of disabling vertigo and intermittent high-frequency tinnitus on the right side. Magnetic resonance images showed a small, contrast-enhancing lesion in the fundus of the right IAC, which was suspicious for vestibular schwannoma. During surgical exploration, a large venous loop was found extending into the IAC and compressing the vestibulocochlear nerve. The vessel was mobilized and rerouted out of the IAC. The presumed vestibular schwannoma at the cochlear fossa was left in situ. The patient's symptoms resolved immediately after surgery. Hearing was unchanged postoperatively. On follow-up, there has been no growth of the contrast-enhancing lesion in the IAC for 3 years so far.Disabling vertigo can also be caused by venous microvascular compression of the vestibulocochlear nerve inside the IAC and may be treated successfully by microvascular decompression. A sensitive, conservative approach to lesions in the fundus may be justified in the presence of an additional, more prominent pathology that causes compression of the vestibulocochlear nerve.

Abstract
The aetiology of acute hearing loss is mostly idiopathic like sudden sensorineural hearing loss and rarely infectious or vascular. Several studies and meta-analyses of pharmacotherapy are reviewed: In chronic tinnitus there is no indication for pharmacotherapy; sometimes a possible psychosomatic comorbidity has to be treated with psychopharmaceutical agents. Despite a low level of evidence treatment with steroids and initially plasma expanding infusions is recommended for acute tinnitus if there is no spontaneous remission. Intratympanic steroid therapy can be used as an alternative if there is severe hearing loss together with tinnitus.

Abstract
OBJECTIVES To estimate the effect of recovery of idiopathic sudden hearing loss under placebo (first aim) and under medical therapy (second aim). STUDY DESIGN Systematic review and meta-analysis. METHODS A total of 1,674 studies published between January 1974 and April 2009 were found following suggestions in the Cochrane Handbook for Systematic Reviews. After filtering by criteria of Cochrane Collaboration, four trials remained for continuous and two for dichotomous data. RESULTS Using Review Manager, weighted mean difference as well as standardized mean effect of hearing recovery were calculated and pooled. The values for weighted mean difference of hearing gain in dB were 0.79, 95% confidence interval (CI) (-2.04-3.61) and for standardized mean effect 0.06, 95% CI (-0.13-0.24), respectively, which computationally favors active treatment, but statistically is not significantly different from no effect (0 dB). This was in accordance to the comparison of descriptive means between recovery under placebo with 14.3 dB and active treatment with 15.8 dB hearing gain. Treatment effect of dichotomous data (hearing gain vs. no hearing gain) suggested a statistically significant better outcome for active treatment; the odds ratio (OR) [fixed] is 2.18 (1.06-4.46). CONCLUSIONS In five different statistical analysis methods used, treatment effect of medical therapy was slightly better than recovery under placebo in which spontaneous recovery could be assumed, but no significant effect was detected. Against the background of recovery under placebo of 14.3 dB vs. 15.8 dB hearing gain of active treatment as averages of all measured frequencies, recovery under placebo seems not to have worse outcome than recovery under medical therapy.

Abstract
In cases of acute unilateral deafness, no consensus exists as to whether tympanotomy and sealing of the round window should be performed routinely. To further address this issue, we conducted a retrospective study of pre-, intra-, and postoperative findings in 97 patients who had undergone exploratory tympanotomy (EXT) after the onset of sudden and severe unilateral deafness. Our goal was to ascertain, if we could, whether the benefits of EXT outweigh the risks. We also took into account the effects of perilymph fistula (PLF) on the etiology of sudden hearing loss and postoperative outcomes. We found that routine EXT was indeed beneficial for these patients. It was associated with a very low surgical complication rate, and its effects on hearing as assessed by objective measures were beneficial. The greatest benefits were seen in patients who underwent EXT within 7 days after the onset of their hearing loss. With respect to PLF, we found that the presence or absence of the “typical history” of PLF (i.e., a sudden unilateral hearing loss within 48 hours after a precipitating trauma or physical exertion) had no bearing on whether a PLF was actually present in our group; nor was vertigo a reliable predictor of PLF. We recommend that EXT be performed on all patients with new-onset acute unilateral deafness, barring any contraindications, of course. The absence of a typical history of PLF should not dissuade the surgeon from proceeding with EXT.

Abstract
Hypoxia/ischemia may play an important role in the pathogenesis of sensorineural tinnitus due to the characteristics of the cochlear blood supply. In addition, hypoxia modulates molecular processes both in the acute and chronic forms of tinnitus. Transcription factor HIF-1 (hypoxia-inducible factor) may play a key role in the cells' adaptation to hypoxia and ischemia, while under hypoxic/ischemic conditions, HIF-1 induces changes in the gene expression which may contribute to the remodeling of particular structures within the cochlea. Disturbances in the cochlear blood supply may result in membrane changes, perineural edema, inflammation, disturbances in ion homeostasis and in the formation of reactive oxygen species. Thus, the pharmacotherapy of acute tinnitus may be aimed at the improvement of cochlear blood supply and the prevention of acute processes leading to cell damage. Pharmacotherapies with colloidal plasma substitutes, vasodilators, calcium antagonists, procaine, and cortisone have been described in the literature and are discussed here. Many of the pharmacological treatments have not been validated in double blind studies. Although it is impossible to deduce the cause of tinnitus from a drug's efficiency, there is some evidence that it can be effectively suppressed by improving blood supply, at least at certain stages. The aim is to achieve an improved pharmacotherapy by means of sophisticated diagnostic instruments for classifying particular types of tinnitus.

Abstract
OBJECTIVE To investigate whether intravenous steroid and vasoactive therapy in the acute postoperative period improves hearing outcome in patients who develop acute deafness after attempted hearing preservation surgery for acoustic neuroma (AN) through a retrosigmoid or a middle cranial fossa approach. STUDY DESIGN AND SETTING Retrospective controlled study in a tertiary care center. Thirty-six patients who had developed acute deafness after hearing preservation surgery for treatment of an AN were reviewed. Preoperative AAOHNS hearing class was A in 2, B in 2 and D in 32 patients. Twenty-seven patients were treated with prednisolone, hydroxyethyl starch 3% and pentoxifylline intravenously for a period of at least 5 days. Nine patients (controls) did not receive any specific steroid or vasoactive therapy. RESULTS All patients in both groups remained deaf. CONCLUSIONS Intravenous therapy with prednisolone, hydroxyethyl starch 3% and pentoxifylline in the acute postoperative period does not improve hearing in patients who develop acute deafness after attempted hearing preservation surgery for AN.

Abstract
Novel drug release microimplants (0.8 x 1.14 mm; custom-made by Leiras, now Schering OY, Finland) of slow- and fast-release types containing either 0.9 mg beclomethasone or no drug at all were placed unilaterally onto the round-window membrane (RWM) of 45 guinea pigs for a maximum duration of 28 days. The following parameters were tested on days 1, 14 and 28 after implantation: threshold levels of beclomethasone in the perilymph of the scala tympani, auditory brain stem responses (ABR thresholds and ABR threshold shifts), RWM morphology and hair cell loss (cytocochleograms). None of the animals in the non-implanted control group (n = 5) or placebo implant group (n = 15), but all animals in the slow-release-type implant group (n = 15) and fast-release-type implant group (n = 15) revealed the presence of beclomethasone on day 1 (34.9 and 64.3 pg/microl, respectively), day 14 (43.8 and 46.9 pg/microl, respectively) and day 28 after implantation (4.7 and 60.5 pg/microl, respectively). Histology of the RWMs appeared normal, and cytocochleograms revealed no inner hair cell loss and outer hair cell loss within normal ranges (from 0.5 +/- 0.4 to 0.8 +/- 0.2% per cochlea) in both ears in all experimental groups at any time during examination (days 1, 14 and 28). Initial values of ABR thresholds at 3, 6, 9 and 12 kHz did not differ significantly in any of the experimental groups. In non-implanted controls, no significant differences of ABR thresholds were observed in all frequencies tested in either ear on days 1, 14 and 28 compared to initial values, and ABR threshold shifts ranged from -3 +/- 5 dB (min.) to +5 +/- 7 dB (max.). On day 28 after implantation, there were no significant differences of ABR threshold shifts between this and the implant groups, except for 6 kHz of the slow-release device. Therefore, the placebo implants, the slow-release and the fast-release beclomethasone implants appear suitable for further experiments.

Abstract
BACKGROUND We question whether patients with acute tinnitus can be differentiated in their perceived handicap and emotional distress. Dysfunctional mechanisms for coping with stress and illness in patients with acute tinnitus were investigated. METHODS Twenty patients (symptoms for less than 1 week) were examined for distress due to tinnitus (TF), degree of depression (BDI), global distress (SCL- 90-R) and coping with stress (SVF). RESULTS Patients could be differentiated in terms of their psychological distress and annoyance caused by the symptoms. There is a high correlation between the degree of depression, dysfunctional way of coping with stress and emotional distress caused by tinnitus. Dysfunctional stress coping strategies are found more frequently in highly affected patients. CONCLUSION Patients with acute tinnitus can be differentiated in terms of their distress and the psychological impairment caused by their symptoms. These results suggest that the immediate reaction to the manifestation of tinnitus might be of prognostic value for the level of emotional distress experienced in chronic tinnitus. The question arises of whether psychological intervention in the acute stage of tinnitus might be beneficial.

Abstract
The etiology of sudden sensorineural hearing loss is still unclear and is thought to result from disturbances of microcirculation, infectious causes, or autoimmune disorders. So far standard therapy did not show clear improvement over spontaneous remission rate, which is assumed to be about 50% [Nakashima et al., Acta. Otolaryngol. Stockh. 514:14-16, 1994; Schuknecht and Donovan, Arch. Otorhinolaryngol. 243:1-15, 1986; Harris and Sharp, Laryngoscope 100:516-524, 1990; Mayot et al., Clin. Immunol. Immunopath. 68:41-45, 1993; Gussen, Ann. Otol. Rhinol. Laryngol. 85:94-100, 1976]. Elevated blood viscosity due to high fibrinogen levels is supposed to cause decreased cochlear blood flow and thus initiate sudden hearing loss. The specific lowering of fibrinogen immediately decreases plasma viscosity exactly to the desired extent and should lead to improved cochlear blood flow [Suckfüll et al., Acta. Otolaryngol 119:763-766, 1999; Suckfüll, Lancet 360:1811-1817, 2002; Walch et al., Laryngol. Rhino. Otol. 75:641-645, 1996; Suckfüll et al., Otol. Neurotol. 23:309-311, 2002]. In a prospective uncontrolled pilot study on 36 patients with unilateral sudden onset sensorineural hearing loss (SHL) we tried to establish that 1-3 specific fibrinogen aphaereses alone improve recovery of hearing and that it is possible to lower fibrinogen to the target of 80-100 mg/dl without important side effects. Pure tone audiometry was carried out immediately before and after each aphaeresis as well as at 2 and 4 weeks and 6 months after treatment. Sixteen patients recovered spontaneously before undergoing fibrinogen adsorption. All 20 aphaeresis patients improved during immunoadsorption; in 60% of patients auditory thresholds returned to normal after the first immunoadsorption and treatment could be discontinued, in another 20% of patients complete recovery was reached after 4 weeks. The mean plasma fibrinogen concentration of the 20 patients before the first aphaeresis session was 308.1 +/- 51.5 mg/dl. Immediately after the first treatment session, the fibrinogen concentration was lowered to 100.7 +/- 25.3 mg/dl (P < 0.001). The second and third sessions also showed highly significant reductions in plasma fibrinogen. No important side effects were seen. In conclusion, specific fibrinogen adsorption is a promising new treatment modality that should be tested in a prospective, randomized controlled trial in patients with sudden hearing loss.

Abstract
OBJECTIVE The question whether progressive sensorineural hearing loss during childhood is the fateful course of a main illness has been discussed controversially over 60 years. No medicamentous therapy with satisfactory results has been described in the literature. The goal of this study was to determine whether an infusion therapy, developed for the treatment of sudden hearing loss in the elderly, can induce recovery after progression in sensorineural hearing loss during childhood. METHODS Out of 20 children suffering from acute progression in sensorineural hearing loss, seven children were treated with an infusion therapy containing prednisolone, pentoxifylline and a plasma expander (group I), and 13 children were not treated (group II). All children were advised not to use hearing aids for 6 weeks. RESULTS In group I, we observed partial to complete restoration of hearing threshold towards the original hearing threshold given by previous routine controls in 6/7 children. In group II, only three children recovered, with the state of ten children's' hearing loss remaining unchanged. The long-term follow-up, however, showed no distinct difference in either group. CONCLUSION Infusion therapy can be helpful when treating acutely progressing sensorineural hearing loss during childhood. The benefit for communicative competence has to be discussed. Further studies should be conducted.
