RESUMO

In modern clinical medical practice, middle-ear infection is a frequently reported condition. If untreated, persistent inflammation caused by infection may lead to perforation of the mastoid process or other portions of the temporal bone. When the middle-ear abscess penetrates the surrounding bone and invades the mastoid process, it causes mastoiditis. Abnormal osseous fistulae were observed on the temporal bones of individuals M137 and M199, which were unearthed in Qufu Olympic Sports Center Cemetery in Qufu City, Shandong Province, and date to the Warring States to the Han Dynasty (475 BCE-220 CE). Microscopic observation and CBCT were used to examine the lesions. A differential diagnosis suggests that the lesions were related to mastoiditis, and based on reference studies, burial information, and paleopathological observation, pollution in the living environment and poor living conditions may be potential factors that caused individuals M137 and M199 to suffer from mastoiditis. The two examples from Qufu are the earliest reported cases of mastoiditis from China; however, infections in the middle ear often go unnoticed in archaeological samples.

RESUMO

OBJECTIVE: To evaluate processes causing two types of mastoid hypocellularity (Type 1 and Type 3), and to provide histomorphological criteria for a differential diagnosis in archaeological human bone. MATERIALS AND METHODS: Eight human crania from the early medieval cemetery in Dirmstein (Rhineland-Palatinate, Germany) displaying secondary obliteration of mastoid air cells were analyzed using light-microscopy and backscattered electron imaging. RESULTS: In Type 1 hypocellularity, obliteration starts in the non-pneumatized portion of the mastoid process and extends into the pneumatized portion. The findings could represent a chronic, maybe recurrent condition related to a pathologically altered middle ear mucosa in early childhood. In Type 3, a sequence of resorptive and proliferative processes are present and are consistent with a healing stage of mastoiditis. CONCLUSIONS: Using histomorphology, in vivo processes resulting in different types of mastoid hypocellularity can be assessed, even in bones that have undergone some degree of diagenesis. SIGNIFICANCE: The study provides methods to evaluate the etiology of histomorphological changes of the mastoid process, which potentially provides insight into the presence of infection and inflammation in past populations. LIMITATIONS: Diagenetic modifications of archaeological bone can hinder assessment of histomorphological change, requiring careful evaluation during analysis. SUGGESTIONS FOR FURTHER RESEARCH: Including histomorphology in future studies on archaeological human crania can contribute to an improved differential diagnosis of pathological conditions in the middle ear region.

RESUMO

OBJECTIVE: This study gives details of a rare case of petrous apicitis that presented as Gradenigo's syndrome and was managed surgically. METHOD: This study presents a case report and review of the literature. RESULTS: A four-year-old female was admitted for failure to thrive following recent sinusitis. Physical examination was positive for right sided facial pain, photophobia and right abducens nerve palsy. Subsequent magnetic resonance imaging revealed a 1.3 × 1.7 × 1.4 cm abscess encompassing the right Meckel's cave. A computed tomography scan showed petrous apicitis and otomastoiditis, confirming Gradenigo's syndrome. The patient was taken to the operating theatre for right intact canal wall mastoidectomy with myringotomy and tube placement. She was discharged on six weeks of ceftriaxone administered by a peripherally inserted central catheter line. At a two-week post-operative visit, she showed notable improvement in neuropathic symptoms. CONCLUSION: This study presents a rare case of petrous apicitis managed surgically without the need for a craniotomy or transcochlear procedure.

RESUMO

BACKGROUND: Rhabdomyosarcoma originating in the mastoid is rare and may be misdiagnosed as an infectious mastoiditis due to overlapping clinical and imaging features. We aimed to identify distinguishing characteristics to facilitate earlier diagnosis and treatment. METHOD: Here we describe a case report and a systematic review of 23 reports describing previous cases of mastoid rhabdomyosarcoma. We compare these patients to a systematic review of patients with infectious mastoiditis and identify distinguishing clinical features. RESULTS: A total of 43 patients with rhabdomyosarcoma of the mastoid were identified and compared with patients with mastoiditis. Rhabdomyosarcoma patients were more likely to present with a mass (86%) or cranial nerve dysfunction (83.7%), while mastoiditis patients were more likely to have fever (72.4%), pain (48.2%), and present at a younger age (4.4 vs. 6.1 years). The average lifespan with rhabdomyosarcoma of the mastoid was 7.1 months after diagnosis, with 41.7% of patients alive at the time of report. CONCLUSIONS: Based on abstracted and aggregated information, we identified unique features observed more frequently in each of rhabdomyosarcoma and mastoiditis. These predictive features allow for the differentiation of each diagnosis and avoid the delay of proper treatment.

RESUMO

OBJECTIVES: Recurrent acute mastoiditis is repeatedly reported in the literature, but data to understand the pathogenesis, update treatment recommendations and inform future trials are sparse due to the infrequency of the disease. METHODS: A retrospective chart review from 2001 to 2016 was conducted including 73 children treated for acute mastoiditis. A follow-up survey was attempted for each patient. Bacteriology, method of treatment, hospital course, complications, and otologic history were analyzed. A chi-squared test, Fisher's exact test and Mann-Whitney U test compared recurrent acute mastoiditis to single acute mastoiditis cases. Additionally, a comprehensive PubMed search and review of world literature addressing recurrent pediatric acute mastoiditis was performed for comparative purposes. RESULTS: Among 73 children with acute mastoiditis, six (8%) experienced recurrent acute mastoiditis. Streptococcus pneumoniae was the only bacteria isolated in this group. History of recurrent acute otitis media (>4 per year) prior to the first episode of acute mastoiditis was identified in 24% with single episode of acute mastoiditis and 83% with recurrent mastoiditis (p < 0.05). Fewer intracranial/intratemporal complications were identified among recurrent mastoiditis patients (p < 0.05). In a group of patients treated with more extensive surgical communication during mastoidectomy for primary acute mastoiditis (wide mastoidectomy with broad attic exposure and posterior tympanotomy) no recurrence was observed. CONCLUSION: We identify multiple risk factors associated with recurrence and provide early data supporting anatomic predisposition to the development of recurrent acute mastoiditis. More aggressive opening between the mastoid cavity and middle ear may prevent recurrent acute mastoiditis episodes.

RESUMO

Q fever is a zoonotic disease caused by Coxiella burnetii that usually presents with non-specific or benign constitutional symptoms. Diagnosis is often challenging and, after acute Q fever, 1%-5% of patients can develop chronic disease. We present an 80-year-old male patient who was admitted due to a 3 months history of fever, productive cough, myalgia, weight loss, headache and hearing loss. Chronic Q fever was confirmed by positive antiphase I immunoglobulin G. Frequent locations of chronic infection was discarded, and ear CT revealed a right mastoid infection. He was treated with doxycycline and hydroxychloroquine for 18 months with significant improvement. This is a rare case of chronic Q fever presenting with otomastoiditis that has never been described.

RESUMO

Tuberculosis involving mastoid and ear is an uncommon entity presenting with myriads of non-specific features and difficult to diagnose, being a paucibacillary condition. The involvement of otomastoid compartment is hypothesised to be of haematogenous origin. Rarely it can spread directly via tympanic membrane perforation or via reflux through eustachian tube. The usual picture of presentation tends to be one of indolent ear infection not responsive to usual antibiotic treatment and symptomatology being out of proportion to examination findings. We present a case of aural tuberculosis presenting with zygomatic and Bezold abscess without other symptoms, and the usefulness of GeneXpert test in mycobacterial detection in such paucibacillary conditions.

RESUMO

Ewing sarcoma (EWS) is a primitive neuroectodermal tumor arising in bone or soft tissue. It is the second most common primary bone malignancy of children and adolescents, with a peak incidence in the second decade of life. It most often arises in the long bones of the extremities and pelvis. Here, we present a novel case of EWS arising from the mastoid bone in a 5-year-old African American male who presented with symptoms of acute mastoiditis. This unique presentation highlights the importance of considering EWS in a patient who presents with atypical mastoiditis or a rapidly growing mass in the postauricular region.

RESUMO

HYPOTHESIS: The temporal bone shows regional differences in bone development. BACKGROUND: The spreading pattern of acute mastoiditis shows age-related differences. In infants, it spreads laterally and causes retroauricular swelling, whereas in older children, it tends to spread medially and causes intracranial complications. We hypothesized that bone maturation may influence the spreading pattern of acute mastoiditis. METHODS: Eighty participants with normal hearing, aged 3 months to 42 years, participated in this study. Computed tomography (CT) values (Hounsfield unit [HU]) in various regions of the temporal bone, such as the otic capsule (OC), lateral surface of the mastoid cavity (LS), posterior cranial fossa (PCF), and middle cranial fossa (MCF), were measured as markers of bone density. Bone density development curves, wherein CT values were plotted against age, were created for each region. The age at which the CT value exceeded 1000 HU, which is used as an indicator of bone maturation, was calculated from the development curves and compared between the regions. RESULTS: The OC showed mature bone at birth, whereas the LS, PCF, and MCF showed rapid maturation in early childhood. However, there were significant regional differences in the ages of maturation: 1.7, 3.9, and 10.8 years for the LS, PCF, and MCF, respectively. CONCLUSION: To our knowledge, this is the first report to show regional differences in the maturation of temporal bone, which could partly account for the differences in the spreading pattern of acute mastoiditis in individuals of different ages.

RESUMO

In our opinion it is caused by incomplete awareness of the distribution of pathological process and the character of morphological changes in the patients. In this regard, we studied structural changes in the soft and bone tissue taken from various cavities of the middle ear system. Operating material was formed in paraffin after the fixation and proper processing. We proceed with decalcification of bone tissues in 15-20% nitric acid. We painted 5-6 mm thick peels prepared on the rotating microtome with hematoxylin and eosin. The microscopic examination revealed inflammatory-destructive changes in the mucous membrane as well as in the bone tissues, also serous inflammation-fibrin inflammation, and well-expressed edema. The inflammatory infiltration demonstrated the presence of lymphocytes, macrophages, plasmocytes and also predominantly dislocated leukocytes. There were also revealed various amount of glandular structures. The bone tissues - along with the inflammatory infiltration - revealed destructive cells, which contained osteoclast, epithelial cells and fibroblasts. The mentioned structural changes should be assessed as demonstration of an osteitis and osteomyelitis. Based on the above mentioned, we believe that treatment of latent mastoiditis requires surgical method and it is necessary the complete sanitization of not only the granulating tissue but the damaged bone masses. Otherwise, the remaining inflammatory nidus may cause a relapse. The correct treatment of latent mastoiditis in turn will reduce the mortality rate and the percentage of disability.

RESUMO

This article was designed to report a case of otogenic abscess of the temporomandibular joint in a 5 year-old child. The specific feature of this observation is a rare complication of acute otitis media (otogenic abscess of the temporomandibular joint). Of crucial importance for the establishment of the correct diagnosis was the timely evaluation of the state of the temporomandibular bones by means of CT examination.

RESUMO

UNLABELLED: Several systemic diseases, including granulomatous and infectious processes, tumors, bone disorders, collagen-vascular and other autoimmune diseases may involve the middle ear and temporal bone. These diseases are difficult to diagnose when symptoms mimic acute otomastoiditis. CASE REPORTS: The present report describes our experience with three such cases initially misdiagnosed. Their predominating symptoms were otological with mastoiditis, hearing loss, and subsequently facial nerve palsy. The cases were considered an emergency and the patients underwent tympanomastoidectomy, under the suspicion of otitis media with cholesteatoma, in order to remove a possible abscess and to decompress the facial nerve. The common features were the presence of severe granulation tissue filling the mastoid cavity and middle ear during surgery, without cholesteatoma. The definitive diagnoses was made by means of biopsy of the granulation tissue from the middle ear, revealing granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis) in one case, middle ear tuberculosis and diffuse large B-cell lymphoma respectively. After specific associated therapy facial nerve functions improved, and atypical inflammatory states of the ear resolved. CONCLUSIONS: As a group, systemic diseases of the middle ear and temporal bone are uncommon, but aggressive lesions. After analyzing these cases and reviewing the literature, we would like to stress upon the importance of microscopic examination of the affected tissue, required for an accurate diagnosis and effective treatment.

RESUMO

Tuberculous otitis media and mastoiditis, or tuberculous otomastoiditis, is a rare but well-described infectious process occasionally affecting individuals in the United States but more frequently seen in countries where tuberculosis is endemic. Infection may be primary and occur through mucus aspirated through the Eustachian tube. Alternatively, organisms may secondarily infect the nasopharynx when expectorated from the lungs and, less frequently, may be hematogenously spread. Chronic otorrhea and hearing loss are common symptoms, and extensive perforation of the tympanic membranes and facial nerve paralysis are routinely described. Diagnosis is made by direct culture of Mycobacterium tuberculosis, although more recently, molecular techniques have been used. Successful treatment of tuberculous otomastoiditis routinely involves surgical intervention combined with prolonged antituberculosis therapy.

RESUMO

BACKGROUND: Delayed antibiotic treatment for acute otitis media (AOM) is recommended for children >6 months with nonsevere illness, no risk factors for complications or history of recurrent AOM. This study evaluates relationship between delayed antibiotic treatment for antecedent AOM and severity of subsequent acute mastoiditis admission. METHODS: A prospective observational study of children aged 0-14 years admitted with acute mastoiditis to 8 hospitals between 2007 and 2012 calculates rates of severe acute mastoiditis admission [defined by ≥1 of the following: complication (mastoid subperiosteal abscess, brain abscess and sagittal vein thrombosis), need for surgical procedure and duration of admission >6 days].Severe acute mastoiditis admissions in children with antecedent AOM treated with immediate antibiotics were compared with those with delayed antibiotic treatment. RESULTS: Antecedent AOM was diagnosed in 216 of 512 acute mastoiditis admissions (42.1%), of whom 159 (73%) immediately received antibiotics, and 57 (27%) had delayed antibiotic treatment. Higher rate of recurrent AOM was noted in the immediate compared with delayed antibiotic treatment group (29% vs. 8.7%, P = 0.0021). Complication rates were 19.5% versus 10.5% (P = 0.12), rates of surgical procedures required, 30% versus 10% (P = 0.0033); admission rates >6 days, 37% versus 29% (P = 0.28) for immediate antibiotic therapy and delayed antibiotic treatment. On logistic regression analysis, immediately treated AOM patients had increased need for surgery for acute mastoiditis with adjustment for history of recurrent AOM (relative risk: 3.2, 95% confidence interval: 1.4-7.0). CONCLUSIONS: Delayed antibiotic treatment for antecedent AOM is not associated with an increase in severity parameters in subsequent acute mastoiditis admission.

RESUMO

The results of surgical treatment of 62 patients, suffering chronic purulent middle otitis, were analyzed. The structure of mastoid processus and attic constitutes a base for choice of middle ear surgical sanation. Sanation operation with preservation or reconstruction of external acoustical meatus posterior wall was finished with combined mastoidoplasty using autobone, spongioid bone bioimplant Tutoplast or bioceramic material "Sintekost". Achievement of a steady sanating effect have promoted in late postoperative period a trustworthy lowering of the perception threshold of the bone--conducted sounds as on vocal, and also on high frequencies, while of the air--conducted sounds--on vocal frequencies. This permits in perspective to perform a hearing--improving operations with good functional result.

RESUMO

BACKGROUND AND PURPOSE: MR imaging is often used for detecting intracranial complications of acute mastoiditis, whereas the intratemporal appearance of mastoiditis has been overlooked. The aim of this study was to assess the imaging features caused by acute mastoiditis in MR imaging and their clinical relevance. MATERIALS AND METHODS: Medical records and MR imaging findings of 31 patients with acute mastoiditis (21 adults, 10 children) were analyzed retrospectively. The degree of opacification in the temporal bone, signal and enhancement characteristics, bone destruction, and the presence of complications were correlated with clinical history and outcome data, with pediatric and adult patients compared. RESULTS: Most patients had ≥50% of the tympanic cavity and 100% of the mastoid antrum and air cells opacified. Compared with CSF, they also showed intramastoid signal changes in T1 spin-echo, T2 TSE, CISS, and DWI sequences; and intramastoid, outer periosteal, and perimastoid dural enhancement. The most common complications in MR imaging were intratemporal abscess (23%), subperiosteal abscess (19%), and labyrinth involvement (16%). Children had a significantly higher prevalence of total opacification of the tympanic cavity (80% versus 19%) and mastoid air cells (90% versus 21%), intense intramastoid enhancement (90% versus 33%), outer cortical bone destruction (70% versus 10%), subperiosteal abscess (50% versus 5%), and perimastoid meningeal enhancement (80% versus 33%). CONCLUSIONS: Acute mastoiditis causes several intra- and extratemporal changes on MR imaging. Total opacification of the tympanic cavity and the mastoid, intense intramastoid enhancement, perimastoid dural enhancement, bone erosion, and extracranial complications are more frequent in children.

RESUMO

BACKGROUND: Inflammatory myoblastic tumors (IMTs) are rare, mesenchymal neoplasms most commonly located in areas of previous inflammation. In the temporal bone, these tumors typically present as solitary, space-occupying lesions that clinically resemble chronic otitis media. METHODS: We present a case of bilateral IMTs with facial nerve involvement, sigmoid sinus thrombosis, leptomeningeal enhancement, and seizures. RESULTS/CONCLUSION: This case demonstrates the need for a high index of suspicion of IMT when imaging reveals bilateral mastoid opacification. These tumors are more aggressive than their orbital counterparts and require multimodality therapy to prevent recurrence and alleviate severe neurotologic symptoms.
