The paranasal sinuses and the mastoid air-cell systems are evaginations of the mucous membrane of the nasal and nasopharyngeal cavities . Separate theories regarding their pneumatization have been suggested. However, correlation studies between the two systems giving a possible clue to a common pneumatizing process have been few (1 , 2]. One hundred adult patients without ear disease and minima...

The objective of this case report is to present a patient with chronic headache who was diagnosed with excessive aeration of all paranasal sinuses and mastoid air cells using computed tomography imaging. The volume and linear measurements of all of the cavities revealed values greater than the greatest values reported in the literature. To date, this is the second reported case of excessive enl...

Ear surgeons should be aware of the embryological, anatomical and not to forget physiological aspects of the mastoid cavity when considering this structure as a surgical approach to the temporal bone. Different anatomical ways of access have been described that allow reaching the targeted structures (cf. section 5), trying to avoid fundamental constitutive elements susceptible to injury. In our...

ing creating a radical mastoid cavity, obliteration of the eustachian tube, obliteration of the mastoid cavity with free abdominal fat, and permanent closure of the external ear canal. This technique has been evaluated for a period of less than 1 year, but seems to offer a real potential of disease eradication. In addition to this procedure, a device for sealing the cochlea at the point of entr...

We describe the unusual case of a 9-month-old Caucasian girl with a retropharyngeal abscess secondary to a mastoid abscess who presented with torticollis. The retropharyngeal abscess was caused by pus from the mastoid abscess tracking down under the petrous part of the temporal bone to reach the retropharyngeal space via the fossa of Rosenmüller. We believe that this is the first time that this...

Osteomas of the temporal bone are rare entity with incidence of 0.1% - 1% of all benign tumours of skull. They are slow growing benign lesion of temporal bone. We report a rare case of mastoid osteoma of size more than 5 cm. A 40-year-old female patient presented to us with left post auricular bony swelling of size greater than 5 cm. Diagnosis of mastoid osteoma was made after relevant investig...
