A 20-year-old man was transferred to this hospital because of recurrent ear pain for 8 months despite antibiotics, with new fever and headache. Imaging showed opacification of the middle ears and mastoid air cells and erosion of the right temporal bone.

Anaerobic bacteria are uncommon etiologic agents of acute mastoiditis in children. However, recent studies suggest an increase in the incidence of Fusobacterium necrophorum mastoid infections in the last two decades.

A 60-year-old man presented with a 10-year history of intermittent otorrhea and a 2-month history of swelling of the right postauricular area. Physical examination revealed postauricular swelling with an erythematous skin change of the right ear.

Recent reports have reported an increase in the incidence of acute mastoiditis due to Fusobacterium necrophorum. However, the crude incidence and the specific clinical and laboratory characteristics of F.necrophorum mastoiditis in children have not been described. Our aim was to describe these features, in order to identify high-risk patients.

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.

The objectives of this study were to investigate the incidence of complicated acute otitis media (cAOM) as well as the associated microbiology before and after introduction of the 7- and 13-valent pneumococcal conjugate vaccines (PCV-7 and -13), respectively. CAOM comprises “heavy” AOM (AOM demanding hospitalization), mastodismus (M) and acute mastoiditis (AM).

The aim of our study was to evaluate postoperative mastoid aeration according to the preoperative middle ear disease and investigate the factors affecting it.

Acute mastoiditis remains the commonest intratemporal complication of otitis media in the paediatric population. There has been a lack of consensus regarding the diagnosis and management of acute mastoiditis, resulting in considerable disparity in conservative and surgical management.

Patients with mastoiditis and chronic suppurative otitis media which has small mastoids that make them ideal candidates for modified canal wall down mastoidectomy (MCWD) which contributes to a dry and spacious ear and the maintaining and improving hearing.
