Erste tierexperimentelle und klinische Erfahrungen mit bioaktiver Glaskeramik in der rekonstruktiven Mittelohrchirurgie

The bioactive glass ceramic material (Ceravital) is fully accepted in osseous areas without formation of surrounding fibrous tissue; it is fixed by direct chemical bond. The use of this material in ENT surgery was tested in animals. In 70 rabbit ears, defects were inflicted on the tympanic membrane, ossicular chain and posterior wall of the external auditory meatus. Using standard tympanoplastic procedures, these defects were reconstructed using glass ceramic implants. The histological examinations of the preparations, which were embedded in Methylmetacrylate were performed using transmission light microscopy and fluorescence microscopy with incident light. The reactions between the implant and the host tissue, e.g., mucous membrane, free transplanted fascia and skin, were examined. In 85 patients Ceravital implants were used to reconstruct the ossicular chain and the posterior meatal wall of the outer ear canal. Functional results were satisfactory. No disturbances in woundhealing were observed.

Multidirectional tomagraphy of defects in the facial canal. An experimental investigation.

Defects on the tympanic wall of the facial canal may endanger the nerve in middle ear surgery. Their preoperative tomographic demonstration is therefore valuable. In an experimental investigation an attempt was made to assess the discernibility of artificial defects of different size by hypocycloid and spiral tomography of temporal bone specimens (both isolated and mounted in a tissue-equivalent skull phantom). The thickness of the wall was measured and its influence on the discernibility of the defects discussed.

Diagnosis and treatment of Bell's palsy.

In addition to inability to move the muscles of one side of the face, the patient with Bell's palsy may present other symptoms. The one most frequently encountered is pain; this may be experienced prior to, concomitantly with, or subsequent to the onset of paralysis. It may vary in intensity and duration from relatively mild and transient to, rarely, severe and persistent. The location of the pain can be auricular, postauricular or preauricular. When, during the performance of operations on the ears of patients who were conscious, I applied electric stimulation to the bony inner tympanic wall where the tympanic nerve (Jacobson's nerve) and some of its branches are located these patients complained of pain that was varyingly referred to the three regions mentioned. Another common symptom is epiphora, which may be due to ectropion and to increased secretion. Other eye disturbances include blurred vision and a burning sensation, occurring

Foreign bodies in external auditory canal

A SURVEY of the records of The Mount Sinai Hospital reveaIs that foreign bodies in the external auditory canal occur most commonly in young female children between two and one-half and seven years of age, the right ear being involved more frequently than the left. The experiences of Keen, l however, are not in accord with ours; of 5 I cases of foreign body in his series, omitting the cotton wool variety, there were 23 in the right ear, 27 in the left and one not stated. Keen advanced the explanation that five or six year old children when playing, are really ambidextrous. Previous unsuccessful attempts at removal were the rule in our patients. This is in agreement with the experiences of PoIitzer2 who stated that hardly I o per cent of the cases which come to the specialist had not undergone some manipulation. Some of the foreign bodies removed by us included beans, peas, a piece of porcelain crockery, glass beads of varied sizes and shapes, a tooth, a button, small pieces of graphite from a lead pencil, pieces of onion and cotton. The commonest foreign body encountered in adults, according to Asherson,3 is cotton wool which generally is inserted by the patient and forgotten. Other authors have reported finding fruit seeds, pebbles, glass, shot, insects, larva, coffee beans, slate, etc. Foreign bodies in the external auditory canal may be divided into two groups, those which cause few, if any symptoms and those which cause severe symptoms. I. Foreign Bodies Which Cause Minimal Symptoms. Occasionally during the course of an otoIaryngologic examination, a foreign body may be discovered in the ear. For example, a child was referred to the Out Patient Department for an opinion as to the advisibility of tonsillectomy. On Iooking into the external auditory canal, one saw a round red object which moved when the head was rotated into various positions. It was ascertained upon questioning the parent, that the child frequently pIayed with a red bead necklace. On syringing the external auditory canal with warm water a small bead was washed out. Another patient was seen in the clinic complaining of foul smelling discharge from the right ear of many years duration. The canal wall close to the tympanum was covered with granulations. There was considerabIe purulent discharge in the externa1 auditory canal and the tympanic membrane was not visible. Upon touching the granmations with a probe, the dirty grayish area which was thought to be the inner tympanic wall covered by granulations, moved. With a bayonet forceps, the grayish mass was gently loosened and removed. To our surprise, it was a piece of cotton about +d inch thick, encrusted with calcium salts. The drum was found intact. Within a few days, the granulomata on the canal wall disappeared and “the middle ear discharge” of many years duration ceased. PoIitzer2 reported an instance in which a piece of slate 3 cm. long was present in the external auditory canal for fifty years with no complaints other than deafness. The patient was seventy years old at the time of the r&nova1 of the slate and compIained onIy of poor hearing. Zaufa14 and Lucae5 reported removing cherry stones from the external auditory canal of asymptomatic patients after forty and forty-two years respectiveIy. Wells6 reported a case of deafness of thirty-three years duration resulting from pIacing a pea into the

OSSICULOTOMY IN CHRONIC SUPPURATION OF MIDDLE EAR.

In chronic suppuration of the middle ear where there is necrosis of the soft tissues, tympanic walls and attic, and caries of one or both ossicles, the most rational treatment consists in removing the carious ossicles and all necrosed granular and fibrous tissue in the tympanic cavity. Ossiculotomy for caries has passed the experimental stage and is now recognized not only as justifiable, but a rational method of treatment. There being no such thing as special surgery, we are no more justified in leaving carious bone in the middle ear than is the general surgeon in leaving it in any other portion of the body accessible to removal. The same general and well-known principles of surgery which apply to caries and necrosis of other parts of the body, are equally applicable to the ear, and when we find carious ossicles and necrosed tympanic walls they should be removed and all

SURGICAL TREATMENT OF CHRONIC OTORRHEA.Read in the Section on Laryngology and Otology, at the Forty-fifth Annual Meeting of the American Medical Association, held at San Francisco. June 5-8, 1894.

Surgical treatment of chronic purulent otitis media consists in the excision of necrotic tissue from the tympanic cavity. Instillation, insufflation or mopping of medicaments upon the diseased parts in the drum cavity in many cases result in a cure, but there are many instances in which all these forms signally fail after a long and fair trial. In these unyielding cases it will be found that one or more of the auditory bonelets are necrosed, and in some instances that the tympanic wall in apposition to the necrosed bonelets is itself carious. Manifestly in such cases the plain surgical indication is to excise the diseased bonelets or their remnants, in order to remove septic material from the drum cavity. This improves the drainage of this space, promotes a free application of antiseptics to the tympanum and favors the healing of its muco-periosteal lining. Under such treatment, in most cases,<i>after</i>
