[Value of Papanicolaou exfoliative cytology in diagnosis of cancers of the upper aerodigestive tract]. / Die Wertigkeit der Exfoliativzytologie nach Papanicolaou in der Diagnostik von Karzinomen des oberen Aerodigestivtraktes.

Exfoliative cytology of the pharynx and larynx is a valid tool in the diagnosis of tumours. It is useful in the follow-up of chronic epithelial lesions of these regions and after tumour therapy. Cytological findings in group "Pap III" demand careful follow-up possibly with biopsy. For all other groups a biopsy is only indicated if there is a strong clinical suspicion of a tumour in the individual case. The simple technique of exfoliative cytology makes it an important part of aftercare of patients with malignancy, especially squamous cell carcinoma of the pharynx and larynx. The validity of the method depends on the care with which the specimen is taken and on the experience of the investigator.

[Long-term results of stapedectomy and stapedotomy]. / Langzeitresultate nach Stapedektomie und Stapedotomie.

We have followed up 91 patients for 3 or more years after stapes surgery for otosclerosis, 59 by stapedectomy and 32 by stapedotomy. The surgical technique was chosen randomly. Both surgical techniques achieved significant hearing improvement, but in the higher frequencies (3 kHz) the results of stapedotomy are better and more stable than those after stapedectomy. Surgical revision was necessary in 5 patients--1 after stapedotomy, 4 after stapedectomy.
