Anatomical studies and a correlative management of facial skeleton and skull base injuries with bone plate fixation.

Miniplate osteosynthesis is an osteoplastic procedure that achieves secure stabilization of the midface, even following extensive fractures of the midface and the floor of the anterior cranial fossa. This procedure can be considered a satisfactory operative treatment in terms of cosmetic and functional results. Correlative osteology is discussed and clinical experiences are reviewed.

[Follow-up treatment and after care following operations to improve hearing].

Postoperative treatment is very important for the success of an operation to improve hearing, not only in the immediate postoperative phase, but also in the long term. In most cases this medical treatment can be delegated by otolaryngologists to office practice, providing certain prerequisites are fulfilled. We describe indications and technics for postoperative treatment after stapedectomy and tympanoplasty.

Alfonso Corti (1822-1876)--discoverer of the sensory end organ of hearing in Würzburg.

Alfonso Corti was born at Gambarana in Lombardy. As a medical student he enrolled first at the University of Pavia, later at the University of Vienna. There he received his degree in medicine. In the years 1850/51, in the laboratory of Albert von Kölliker at the University of Würzburg, he described for the first time the sensory epithelium, the spiral ganglion, the tectorial membrane, and the stria vascularis of the inner ear.

The stopping of deuterons in lithium.

The interaction of 52 MeV deuterons with lithium was investigated, in view of the optimization of a lithium target for an intense neutron source based on the d-Li stripping reaction. The experimental results are compared with theoretical calculations obtained from an updated version of the Bragg code. This code describes in detail the interaction of charged particles with matter. Within the experimental uncertainties the theoretical results are well reproduced by the experiments.

Recombinant interferon-alpha-2C in laryngeal papillomatosis: preliminary results of a prospective multicentre trial.

A preparation of interferon-alpha 2C of high purity formed by recombinant DNA technology was used as adjuvant therapy following removal of laryngeal papillomas by cauterization or laser vaporization. Preliminary data on 20 patients are reported and include 11 complete and 7 partial responses. Side-effects included initial temperature elevation, but this subsided and other side-effects were uncommon. No antibodies to the interferon preparation were found in any of the patients.

[Diagnosis of middle ear tuberculosis].

Middle ear tuberculosis is underdiagnosed. Clinical suspicion requires extensive diagnostic and therapeutic procedures. Due to a high degree of error in bacteriological and histological examination they must often be repeated. Indications for tentative diagnosis are given.

[Ethmoidectomy and orbital decompression in endocrine ophthalmopathy].

23 orbita decompression operations were performed in patients suffering from endocrine exophthalmos (Grave's disease) after normalization of thyroid metabolism and systemic corticoid therapy remained unsuccessful. We developed a modification of an external ethmoidectomy. The lamina of the middle nasal concha is carefully preserved, any opening to the nasal cavity is closed. Flap door incisions of the periorbita complete this procedure. Results are good and were followed up for a period of 30 months. The operation resulted in prompt restitution of normal eye position with fast normalization of visual acuity and field. Squint surgery was done in addition.

[Tympanoplasty in children].

Tympanoplasty in childhood is not always the same as in adults. This applies to the indication for the operation, to the operation itself and also to the pre- and postoperative treatment. The rapidly growing and expanding juvenile cholesteatoma offers special problems, and probably has a different cause than the slow growing pearl tumour found in adults. Traumatic cholesteatomas also give the impression of growing faster in childhood. The prognosis for tympanoplasty in cases of mesotympanic chronic otitis media must not be too optimistic because the condition of the mucosa in juveniles is different to that in adults. Pre-operative treatment may take a long time and postoperative treatment may be difficult.

[Noise exposure of the ear during surgery (author's transl)].

We measured the noise generated by three vacuum pipes with different inner diameters in the external ear canal with a probe microphone. The highest level was generated by the largest pipe when solid material blocked part of the entrance. Then we measured peak levels up to 140 dB-C. Such levels generate only low Leq but due to their high on-off ratios they may be dangerous to the ear if repeatedly applied.

[Some problems concerning electric tests in cases with Bell's palsy (author's transl)].

Some draw backs of Neuronography are discussed: 1) Estimating and correlating response levels is very unreliable. 2) It takes four days for some prognosis. A very fine indicator is the area under the response diagramm, that is the area between curve and Zeroline. To calculate this area we have developed a microprocessor based instrument at the ENT-Clinic Würzburg.

[Agenesia and hypoplasia of the conchae nasales and the septum nasi (author's transl)].

The rare case of a congenital aplasia of the conchae nasales on both sides as well as a hypoplasia of the septum nasi is described in a women to whom the age of 78 years was given. A heavy hypotrophy of the paranasal sinuses existed concurrently. The epithelium of the regio respiratoria had developed correctly and in spite of the wide nasal relations no symptoms of a rhinitis atrophicans respectively an ozéna could be identified. A hook-nose was not very striking in its outward appearance. In a women to whom the age of 77 years was given a hypoplasia of the conchae nasales media et inferior was observed. The point of the genesis of these malformations is discussed.

[Clinical-morphological variations of chronic oropharyngitis (author's transl)].

Non-specific chronic inflammatory changes of the oropharyngeal posterior wall show a considerable abundance of variations. An own respectively reorganised classification of the various clinical pictures in chronic oropharyngitis is proposed comprising altogether 8 forms. The micromorphological characteristics of these particular variations which showed repeating lymphoepithelial interactions in the infantile hyperplastic oropharyngitis with definable activity stages have been examined. The observed changes of the posterior wall of the pharynx in the infant might be settled in physiological border regions within the frame of general immunological scaffolding. A largely unconcerned epithelium was always imposing in the inflammatory hypertrophic and atrophic oro-pharyngopathies of the adult so that here a rather submucous "lymphatic inflammation picture" is uppermost.

[New trends in head and neck tumour diagnosis (author's transl)].

Clinical examination and conventional radiology, endoscopy and histology until today form the basis for diagnosis of head and neck tumours. Now magnifying endoscopy, cytology and computerized axial tomography are becoming more and more important. Experience shows that the magnifying endoscope is suitable for every otolaryngologist. Cytology deserves critical appraisal and computerized axial tomography has become important in preoperative tumour assessment.
