The authors report on a series of 24 patients in whom open cavity mastoidectomy cavities were obliterated with bone pâté. The aim of the procedure is to provide the patients with a dry ear which then also reduces the need for frequent out-patient attendances.

Pre-operative Computerized Tomography was performed prior to second look operations in 10 cases to check for cholesteatoma after combined approach tympanoplasty. Three independent opinions were obtained on the CT scans and compared with the operative findings. This small series failed to demonstrate reliable pre-operative radiological detection of cholesteatoma. There was disappointing inter-observer agreement in interpretation of the CT scans.

We present a case of tuberculous otitis media in which a facial palsy occurred after the start of appropriate chemotherapy. To our knowledge this circumstance has not been described previously. It has been argued that radical surgery is completely unnecessary if chemotherapy is commenced early in the disease. We would suggest that this is not always the case, and would advocate a more measured approach.
Actinomycosis of the temporal bone is uncommon. There have only been 24 cases previously reported in the English literature. The responsible organism is Actinomyces israelii, an anaerobic filamentous Gram positive bacterium. While the cervico-facial region is the most common site of the disease, involvement of the temporal bone is rare. The diagnosis can sometimes be made clinically by identification of sulphur granules in a glue-like substrate but in all cases involving the temporal bone, the diagnosis has been made at histopathology. Effective therapy consists of surgery followed by the long-term administration of penicillin.

Traumatic facial nerve neuroma is rare. There are only 10 reported cases in the literature, caused either by physical trauma or chronic inflammation. Traumatic facial neuromata differ from true facial nerve neoplasms in radiological, macroscopic and microscopic appearance, but clinical presentation is less reliable in differentiating the two. Management depends on the pre-operative grade of facial palsy, as this is a benign condition and surgical management carries a risk of further affecting facial nerve function. We present a further case of traumatic facial nerve neuroma following surgery for cholesteatoma. We also review the literature and discuss the management of this condition.

Up to now the importance of the outer ear for the sound transmission is nearly neglected in the otosurgical literature. Nevertheless, surgical procedures can cause severe alterations in the anatomy of the outer ear channel. Necessarily variables which take influence on the acoustic behaviour of the outer ear can get changed by these surgical manipulations. By means of in-situ measurements of the sound-pressure-level near the tympanic membrane the influence of the ear channel/mastoid cavity volume as well as of the size of the outer meatus on the resonance frequency is investigated. In a model of variable volume and several sizes of outer meatus there can be found that the course of resonance-caused sound-pressure augmentation depends on two determining factors: due to the physical-acoustical conditions (Helmholtz-resonator) the peak of the resonance-caused augmentation shifts to lower frequencies the smaller the outer meatus and the larger the volume of the channel/mastoid cavity. Viceversa, an augmentation of the external meatus and an obliteration of the cavity causes a higher resonance frequency. Within values for the volume and the meatal size as can be found in radical cavity surgery the resonance frequency varies in a wide range from 1260 up to 3175 Hz. There is no substantial influence on the amplitude of the sound-pressure augmentation. Measurements undertaken in a temporal bone specimen underline these results: as well as in the model alterations of cavity volume and meatal size lead to partial extensive shiftings of the resonance frequency.(ABSTRACT TRUNCATED AT 250 WORDS)
