Silent mastoiditis and bilateral simultaneous facial palsy.

Silent mastoiditis is a common complication of acute otitis media since the advent of antibiotics. Although most pediatric middle ear inflammations manifest themselves in both ears, otitic facial palsy almost always presents unilaterally. We report an unusual case of bilateral simultaneous facial palsy occurring during the course of a persistent otitis media in a 7-month-old child. Appropriate antibiotic therapy and insertion of ventilating tubes cleared the infectious inflammatory process, resulting in full recovery from nerve dysfunction.

Recurrent therapy resistant mastoiditis by Mycobacterium cheilonae abscessus, a nontuberculous mycobacterium.

A rare case of recurrent mastoiditis is described with abscess formation caused by a nontuberculous mycobacterium (NTM) Mycobacterium chelonae abscessus. The exceptionally slow wound healing after repeated surgical debridement was striking. A literature study showed that in contrast with NTM infections of other parts of the body, infections of the middle ear were most commonly seen in immunocompetent children. If a case of chronic unilateral otitis media shows insufficient response to antibiotic therapy and surgical debridement, mycobacterial infection should be considered. The case described below illustrates the importance of histopathological and microbiological investigations.

Lateral sinus thrombosis complicating mastoiditis.

Although otitis media is easily recognized in the emergency department, its complications can often be missed. We present the case of a patient with mastoiditis with lateral sinus thrombosis that was not diagnosed until a digital subtraction angiogram revealed the occlusion.

Acute pseudomonas mastoiditis in children.

Five children with acute pseudomonas mastoiditis were treated and followed up in our medical center during a period of three years. The main clinical features of the disease include predilection for young male infants, a high rate of local aggressiveness, prolonged hospitalization for repeated surgical procedures, and the need for several courses of intravenous specific antimicrobial therapy. Although correctly diagnosed and promptly treated, these patients may be destined to chronic ear disorders.

Myospherulosis of the mastoid antrum: a case report.

Myospherulosis is a recently discovered iatrogenic disease caused by the implantation during surgery of mineral oil- or petrolatum-based products into various tissues. The condition results from the action of lipid substances on extravasated erythrocytes. The case report presented is the first detailed description of this uncommon, unique inflammatory lesion occurring in the mastoid and is the second otitic case reported in the literature. The lesion mimicked recurrent cholesteatoma 6 years following an intact canal wall mastoidectomy. As in myospherulosis of the paranasal sinuses, the symptoms and findings of otitic myospherulosis are those of the preceding disease.

Endolymphatic-mastoid shunt operation: results of the 24 cases and revision surgery with the silastic sheet.

Endolymphatic-mastoid shunt operation due to Kitahara's method was performed on 24 patients with Meniere's disease. In 14 patients, the vertiginous attack was controlled with satisfactory preservation of hearing for longer than one year. In 2 patients, the vertiginous attack subsided but the hearing worsened. In the remaining 8 patients, long-term control of the vertiginous attack was not attained. Of these 8 recurrent cases, revision was performed on 4, revealing shunt obstruction with granulation or scar tissue. After reopening the endolymphatic sac, a large triangular Silastic sheet was placed into its lumen. The vertiginous attack was controlled thus far in the revised cases using this procedure.

Computerized assessment of the mastoid air cell system.

There have been many arguments on the development of pneumatization of temporal bone. However, a technique for direct volume measurement from high resolution computed tomography has never been reported. The aim of this paper is to develop a technique by using digital image processing to measure the volume of the mastoid air cell system. Forty three ears of 26 healthy subjects (13 males and 13 females) without a history of chronic or exudative otitis media, clear signs of Meniere's disease, severe sensorineural hearing impairment or malformation of temporal bone were eligible for enrolment in this study. Using a digital image processing technique, only the black air cells and tympanic cavity on the CT films are easily selected. Then, after image processing, only areas of these extracted black pneumatized parts are calculated. Consequently, the volume of pneumatized parts of temporal bone could be calculated separately as total volume and as partial volume that divided by several CT planes. The average volume of pneumatization in 43 temporal bones was 5.97 ml. However, since the volume of pneumatization in the temporal bone has traditionally been estimated by analyzing areas on X-ray films, the new method described in this study is significant for its ability to directly measure the volume of pneumatization in the temporal bone.

Spontaneous pneumatocele and pneumocephalus associated with mastoid hyperpneumatization.

We present a case of spontaneous pneumatocele and pneumocephalus associated with mastoid hyperpneumatization. Collections of air such as these are normally due to injury or surgery, and more rarely, infection or tumor; exceptionally they may be spontaneous. The patient in question complained of a progressively enlarging retroauricular mass which increased in size on Valsalva maneuvers; he had no other symptoms. The etiology, skull X-rays, computed tomography and follow-up after surgery are shown here.

Mastoid chloroma as relapse in acute myeloid leukaemia.

Leukaemic infiltration of the petrous temporal bone is uncommon with with improved remission rates and longer survival in leukaemia isolated sites of relapse can be expected more frequently. Mastoid chloroma requires treatment with chemotherapy and radiotherapy. Wide-field mastoidectomy and facial nerve decompression are contraindicated.

The operation of tympanomastoid re-aeration. Physiological repair of the radical mastoid cavity.

The aural cholesteatoma presents the triple problem of danger, discharge and deafness-a problem for many years answered by the classical radical surgery of the last century. The dissatisfaction with this approach has, however, been reflected in the various modifications that have recently culminated in the canal-conserving operation of the past decade or so. Gradually there has been a realization that the inherent, trouble-free stability of the normal healthy ear must be re-created before tympano-plastic repair of the hearing mechanism can be satisfactorily and indeed safely undertaken. This property of stability--the ability of the ear to "look after itself"--is dependent upon a natural environment for the constituent tissues that make up the sound conduction mechanism. Rational tympanoplastic surgery for aural cholesteatoma demands, therefore, both thorough disease excision and physiological reconstruction. This paper describes the priniciples and results of such a technique that I have used over the past ten years with increasing frequency. It combines the disease-excisive efficiency of the radical mastoid operation with a physiological rebuilding of the delicately balanced functional systems of the peripheral hearing mechanism.

True giant-cell tumour of the mastoid. A case report.

The authors describe a case of a very extensive giant-cell tumour of the mastoid in a 5 1/2-year-old girl. This is very rare, and it is only the fourth one documented in the English literature. The age of the patient is of great importance, as well as the fact that the middle and the inner ear were not involved, although the tumour was very extensive. Radical surgical removal of the tumour was performed, as the treatment of choice, without any signs of recurrence one year post-operatively. The diagnostic problems of giant-cell lesions of bones are briefly discussed.

Acute and acute-on-chronic mastoiditis (a five-year experience at Groote Schuur Hospital).

One hundred and thirty patients with acute-on-chronic mastoiditis were managed by the ENT Department of Groote Schuur Hospital between 1980 and 1984 inclusive. Seventy-four patients had cholesteatomas, of whom 78.4 per cent had intracranial extension and 44.6 per cent had intradural extension of the infection. In contrast, of the 56 patients without cholesteatomas, only 23.2 per cent had intracranial extension of the infection. These may be rare conditions in some privileged parts of the world but their lethal potential requires all ENT surgeons to be competent in their management.

Teratoma of the mastoid region in a newborn.

Teratomas are congenital tumours arising from pluripotent cells and usually consisting of tissue arising from all 3 embryonic germ layers. Teratomas are quite uncommon in head and neck sites and to date only 150 such cases have been reported. A rare case of teratoma of the mastoid region in a newborn is reported. The method of diagnosis and treatment are discussed and the literature is reviewed.
