Osteomas occur in all parts of the temporal bone, including the mastoid, squamous, middle
ear, styloid process, internal auditory canal and external auditory canal (EAC). The EAC has
been reported to be the most common site, followed by the mastoid and squamous parts.
Diagnosis is made based on history, clinical examination and radiological findings. Computed
tomography reveals a pedunculated hyperdense mass that usually arises from the
tympanosquamous suture. Surgical removal of EAC osteomas can be achieved using the
endaural or postauricular approaches. It can be performed with a drill or osteotome, either
endoscopically or by using microscopy. This report presents two patients with EAC osteomas
who underwent excision under microscopy using the endaural approach. Surgery is the gold
standard treatment, while close observation may be considered in asymptomatic patients.
Otitis media with effusion (OME) is a condition characterised by a collection of fluid within the middle ear without signs of acute inflammation. It is common in young children, with a bimodal peak at two and five years of age. Eighty percent of children have at least one episode of OME by the age of 10 years. This disease is a common ear problem among children with craniofacial anomalies including cleft palate and Down syndrome (DS).
