Necrotizing otitis externa (NOE), also known as malignant otitis externa (MOE), is a severe and rare infectious disease of the external auditory canal (EAC). Without treatment, it may progress to skull base involvement. The bacteria Pseudomonas aeruginosa is the most common causative agent (90% of the cases), and affects immunocompromised subjects, particularly diabetic patients. Severe chronic otalgia, otorrhea, and cranial nerve palsy are the most common clinical presentations. Patients with NOE are frequently referred to neurosurgery because of the neurological impairment and skull base compromise. The definitive diagnosis is frequently elusive, requiring a high index of suspicion. Several laboratorial tests, imaging modalities, and the histologic exclusion of malignancy may be required. An early diagnosis and aggressive treatment reduce morbidity and mortality. We present four NOE cases to illustrate the spectrum of clinical presentation and complementary exams. According to the literature, more effort for early diagnosis and treatment is required, and neurosurgeons play an important role in this task.

BACKGROUND AND OBJECTIVES: Acute otitis externa is often painful. The aim of this study was to evaluate the efficacy of 10 mg oral prednisolone twice daily for four days in addition to conventional therapy. METHOD: Patients attending general practice clinics in Far North Queensland, Australia, for acute painful otitis externa were given a study capsule with either 10 mg prednisone or placebo. RESULTS: Seventy-three patients were randomised. Results from 19 patients in the intervention group and 11 patients in the control group were analysed. Oral corticosteroids did not decrease the time to being completely pain-free but decreased the time for pain to reduce from more than 'moderate pain' to less than 'moderate pain', from 3.7 days to 2.4 days (P = 0.012, log rank test). DISCUSSION: Oral corticosteroids seem to be effective in reducing more than 'moderate pain' to less than 'moderate pain'. However, this result needs to be confirmed in a larger trial.

INTRODUCTION: Necrotizing otitis externa resolves best with antimicrobial treatment. How to care for these patients and monitor their resolution remains a problem. Our protocol in Bangalore can manage these patients inexpensively and well. MATERIALS AND METHODS: Patients who were referred to our patients became the subjects for this paper. They were managed through our protocol, which consists of IV ciprofloxacin and meropenem, weekly labs, weekly examinations, and photodocumention. RESULTS: Fifty-one people presented with necrotizing otitis externa (NOE) between October 2015 and November 2017 and completed our entire protocol. Forty-six had complete resolution of their disease, while 5 had to undergo surgical removal of necrotic bone. Six of 8 patients with facial weakness had improvement in their House-Brackmann scores. Reduction of self-reported nocturnal pain, dissolution of ear canal granulations, and normalization of the erythrocyte sedimentation rate (ESR) proved to be the most accurate indicators of disease regression. CONCLUSION: Patients are monitored closely with review of their otalgia, examination of their canal, repeated ESRs, effective control of their diabetes, and radiological imaging. All this can be done in a resource-poor country, which in turn serves as a model for the wealthier nations.

PURPOSE: Pseudomonas aeruginosa is commonly found in suppurative perichondritis, but the significant pathogens in non-abscess perichondritis are unclarified. We aimed to explore the bacterial findings and evaluate the effectiveness of different antibiotic regimes in the treatment of patients with perichondritis. METHODS: All patients treated for perichondritis at the two Ear-Nose-Throat Departments in Central Denmark Region (covering 20% of the Danish population) from January 1990 to October 2018 were included. RESULTS: In total, 112 patients with (n = 12) or without (n = 100) abscess were included in the study. Potential pathogens were found in 40 of 55 cultures. P. aeruginosa was recovered in 58% of abscess cases, while Staphylococcus aureus was predominant in non-abscess infections (49%). Eighty-two percent of S. aureus recovered were isolated as heavy or moderate growth. In non-abscess cases, no significant differences in clinical progress (p = 0.65), alteration in antibiotic therapy (p = 0.31), duration of hospitalization (p = 0.65), or frequency of relapse of infection (p = 1.00) or sequelae (p = 0.38) were found between patients treated with antibiotics covering S. aureus vs. P. aeruginosa. CONCLUSIONS: Our findings suggest that intravenous antibiotic therapy covering S. aureus is sufficient and appropriate empirical treatment in the majority of patients with non-abscess perichondritis. Antibiotic coverage should be expanded to include P. aeruginosa if the clinical response is disappointing or cultures grow P. aeruginosa. The risks and downsides to this approach seems limited as only a minority of patients suffered (minor) cosmetic sequelae and relapse of infection in our cohort of non-abscess perichondritis patients initially treated with antibiotics not covering P. aeruginosa.

BACKGROUND Pseudomonal infection is the most common cause of malignant otitis externa (MOE), which typically affects elderly diabetic patients. Fungi are a rare cause of MOE. MOE can be life-threatening if not recognized and treated promptly. It can result in a wide spectrum of complications, including skull-base osteomyelitis, cranial nerve palsy, cerebral venous thrombosis, and brain abscess. Pseudoaneurysm formation of the intracranial vessels is a life-threatening complication of MOE that is seldom reported in the literature. CASE REPORT We report the case of a 66-year-old diabetic man with MOE who was initially treated with antipseudomonal antibiotics after negative initial culture results. His MOE resulted in a cascade of complications, including facial nerve palsy, skull base osteomyelitis, and sigmoid sinus thrombosis, and culminated in left maxillary artery pseudoaneurysm formation resulting in massive epistaxis and hemodynamic instability. Endovascular embolization resulted in a successful obliteration of the pseudoaneurysm. A subsequent functional endoscopic sinus surgical (FESS) tissue biopsy confirmed Candida glabrata as the etiological agent. The patient was successfully treated with antibiotics and antifungal and anticoagulation therapy, and was discharged home in good condition. CONCLUSIONS A high index of suspicion for the diagnosis of fungal MOE, particularly in intractable cases of MOE with negative initial cultures, should be maintained. Pseudoaneurysm formation is a life-threatening complication of MOE that is seldom reported in the literature and should be suspected in any patient with MOE who presents with epistaxis or intracranial bleeding.

OBJECTIVE: Necrotising otitis externa is a severe inflammatory process affecting soft tissue and bone, mostly in diabetic patients. Diabetic patients are also at risk of diabetic foot osteomyelitis, another inflammatory condition involving soft tissue and bone. This review aimed to describe the similarities and differences of these entities in an attempt to further advance the management of necrotising otitis externa. METHOD: A PubMed search was conducted using the key words 'otitis externa', 'necrotising otitis externa', 'malignant otitis externa', 'osteomyelitis' and 'diabetic foot'.Results and conclusionThe similarities regarding patient population and pathophysiology between necrotising otitis externa and diabetic foot osteomyelitis raise basic questions concerning the effects of long-standing diabetes on the external ear. The concordance between local swabs and bone cultures in diabetic foot osteomyelitis is less than 50 per cent. If this holds true also to necrotising otitis externa, the role of deep tissue cultures should be strongly considered. Similar to diabetic foot osteomyelitis, magnetic resonance imaging should be considered in selected necrotising otitis externa subgroups.

BACKGROUND: Otitis externa secondary to irritant or chemical exposure is well documented; however, specifically secondary to jet fuel exposure and its associated toxicology is not. Over 2 million military and civilian personnel per year are occupationally exposed to aviation fuels. CASE REPORT: An aircraft maintainer presented with noninfectious acute otitis externa secondary to external ear canal exposure to JP-5 jet fuel. Proper exposure guidelines were followed, but it was not realized that the external ear canal was involved. The first symptoms to emerge were vertigo, dizziness, and disequilibrium; however, on physical exam it appeared that there was no middle ear involvement. DISCUSSION: Otitis externa normally does not present with vestibular symptoms as the pathology affects the external ear canal dermal tissue. Upon review of JP-5's toxicology profile, dermal absorption is a route of entry and can cause general neurological symptoms, including loss of coordination. This case highlights potential deficiencies in the standardized safety data sheets that are used after exposure. Without mention of possible auricular exposure one may focus on the logical protection of the eyes, mouth, and visible skin. This is concerning due to potential delayed exposure symptoms, dermal absorption, high level of dermal destruction, and the close proximity to the sensory system. The goal of this case report is to improve the knowledge of providers caring for personnel who may be exposed and to suggest possible revisions to the Safety Data Sheets for jet fuel.Long RJ, Charles RA.

OBJECTIVE: To analyse the clinical outcomes of biodegradable synthetic polyurethane foam versus ribbon gauze and ear wick in the treatment of severe acute otitis externa. METHODS: Ninety-two adults with severe acute otitis externa were randomly assigned to groups receiving ear wick (n = 28), ribbon gauze (n = 34) or biodegradable synthetic polyurethane foam (n = 30). Clinical efficacy, in terms of otalgia, oedema, erythema and tenderness of the external auditory canal, was assessed before packing was applied and at follow up on the 3rd and 7th days of presentation. RESULTS: All packing materials were associated with improved otalgia and oedema on the 3rd day; however, there were significant differences between biodegradable synthetic polyurethane foam and the other packing materials, and there was no significant reduction in tenderness in the biodegradable synthetic polyurethane foam group on the 3rd day. In the ribbon gauze and ear wick groups, improvements in all clinical efficacy scores were statistically significant for all pairwise comparisons. CONCLUSION: The three packing materials were all quite effective in treating severe acute otitis externa, but ear wick and ribbon gauze were superior to biodegradable synthetic polyurethane foam for relieving signs and symptoms, especially on the 3rd day.

OBJECTIVE: To identify epidemiological and pathophysiological factors, and treatment strategies, in external auditory canal cholesteatoma and benign necrotising otitis externa. METHODS: A retrospective case study was conducted of patients suffering from external auditory canal cholesteatoma and benign necrotising otitis externa admitted to tertiary hospitals, in the Capital Region of Denmark, over a five-year period. RESULTS: Eighty-three patients (95 ears) with external auditory canal cholesteatoma or benign necrotising otitis externa were identified. A minimum incidence rate of 0.97 per 100 000 inhabitants per year was demonstrated. Sixty-eight per cent of cases had a history of smoking. Most lesions (74 per cent) were localised in the floor of the ear canal. Treatment time was 3.2 months for patients who had surgery and 6.0 months for those who received conservative treatment. CONCLUSION: It is suggested that external auditory canal cholesteatoma and benign necrotising otitis externa are in fact the same disease, and therefore the diagnosis of external auditory canal cholesteatoma should be changed to benign necrotising otitis externa. Microangiopathy has a leading role in the aetiology. Surgery should be conducted in most cases.

The objective of the present work was to study microflora of the external auditory meatus in the patients presenting with bacterial otitis externa diffusa. The authors have analyzed the results of microbiological investigations involving 102 patients with this condition undergoing the treatment with 'Polidexa'. The characteristic of species composition of microflora associated with otitis externa diffusa is presented. The sensitivity of the most common pathogens responsible for the development of this pathology towards antibiotics contained in ear drops has been analysed. The advantages of the use Polidexa for the treatment of this acute ear disease are described.

Cutaneous leishmaniasis typically presents as a painless papule progressing to an ulcer or plaque. In this case study of the ear, the disease manifested as a small painful bump progressing into redness and swelling about the ear with purulent drainage. After multiple oral/intravenous antipseudomonal, antistaphylococcal, and antifungal treatments, there was no improvement. The skin progressed to an erythematous plaque and hemorrhagic ulcer; punch biopsy and speciation revealed Leishmaniasis guyanensis. The patient was switched to a seven-dose course of intravenous L-amphotericin B (visceral leishmaniasis protocol). Within 21 days, pain and edema resolved and the ulcers healed. Three-month follow-up demonstrated no recurrence. Further studies are needed to evaluate the use of L-amphotericin B in Leishmaniasis guyanensis.

The objective of the present study was to evaluate the clinical effectiveness and safety of the local application of triderm for the treatment of diffuse external otitis. The study included 68 patients presenting with bacterial and fungal diffuse external otitis. The treatment in the form of local empiric therapy was continued till the results of microbiological treatment became apparent. The beneficial outcome achieved in 91.2% of the patients was clinically manifest as the regression of the inflammatory process in the external auditory meatus. No complications, such as ototoxic events, either local or systemic allergic reactions, were documented. The authors substantiate the possibility of the application of the medication under consideration for the treatment of diffuse external otitis based on the knowledge of the mechanism of the actin of its constituent components, viz. betamethasone, dipropionate, gentamicin sulfate, and clotrimazole, taking into account the occurrence of the most common causative agents of diffuse external otitis. It is concluded that triderm is a safe medication for the local application and, probably, for the initial empiric therapy of diffuse external otitis to be continued till the results of the microbiological treatment become apparent.

OBJECTIVES/HYPOTHESIS: On the basis of clinical observations, the shape of the osseous external auditory canal (OEAC) has often been seen as an etiological factor in troublesome cavities after modified radical mastoidectomy. STUDY DESIGN: Retrospective analysis of CT scans. METHODS: To assess the role of the shape of the OEAC in troublesome modified radical cavities using computed tomographic scans of three groups of patients (without pathology and with or without draining cavities), we determined the depth of the pretympanic recess (DPTR) and its anterior curvature (ACPTR). In addition to looking at the shape of the OEAC, we also studied the role of any remaining mastoid air cells in relation to troublesome radical cavities, as well as the consultation frequency. RESULTS: The DPTR was significantly deeper in draining cavities than in ears without pathology and dry cavities. No difference in the ACPTR was observed. The presence of remaining mastoid air cells is significantly associated with the presence of a troublesome radical cavity. CONCLUSIONS: The shape of the OEAC (i.e., the DPTR) is a contributory factor to the drainage of modified radical cavities. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:693-698, 2016.

Malignant otitis externa (MOE) usually affect patients with systemic diseases, especially diabetes mellitus. MOE is a mainly unilateral disease. Given that around 90% of human adults are right-handed we hypothesized that hand preference might be one of the factors involved in the development of MOE. All 38 of the patients whom we treated for MOE between August 2009 and November 2012 (28 males and 10 females, age range 43-91 years) had poorly controlled diabetes mellitus, and all of them reported itching in the involved ear. The difference in the laterality of MOE among our right- and left-handed subjects was significant: right hand dominance was associated mostly with right-sided MOE (24/34) and left hand dominance was associated with occurrence of MOE only in the left ears (4/4, p=0.006). These findings point to an unexpectedly strong relationship between the patient's handedness and laterality of his/her MOE, leading us to hypothesize that the development of MOE might be attributable to self-inflicted local trauma to the ear canal on the same side as the dominant hand.

The objective of the present study was to compare the results of different surgical approaches to the treatment of tympanoplasty in the patients presenting with "dry" mesotympanitis. We compared the morphological and functional outcomes of tympanoplasty in 49 patients allocated to the three study groups. Group 1 was comprised of 28 patients that underwent tympanoplasty using the endaural (intrameatal) approach through an ear speculum. Group 2 consisted of 16 patients that underwent tympanoplasty using the endaural(intrameatal) approach through type A and B intercatilaginous incisions by the method of Heermann, Group 3 included 5 patients who underwent tympanoplasty using the postaural transcanal approach. The analysis of the outcomes of surgeries has demonstrated that the best morphological and functional results were obtained in the patients of groups 2 and 3.

The objective of the present study was to estimate the efficacy and safety of candibioic designed for the treatment of the patients presenting with diffuse otitis externa and chronic otitis media. The open randomized trial included 40 patients with diffuse otitis externa and 40 ones with chronic otitis media who had undergone a surgical sanitation procedure. Their standard clinical and otorhinolaryngological examination was supplemented by the characteristic of clinical symptoms and personal complaints using the 10-score scale. The composite preparation candibiotic was found to be equally effective for the treatment of both diffuse otitis externa and chronic otitis media. The results of the study give reason to recommend the use of candibiotic as an efficacious and safe drug for the treatment of these conditions.
