Comparative Study[Fine needle capillary cytology versus fine needle aspiration cytology--a comparison of quality between puncture techniques in the ENT area].
Needle aspiration is currently a widely used technique in the diagnosis of unclear lesions in the head and neck region. We present a modified technique of fine needle biopsy in ENT, "fine needle capillary technique". The basics of this technique were developed by Zajdela and coworkers (1987) as a cytological method of fine needle biopsy in benign and malignant mammary tumors. Fine needle capillary technique does not require aspiration of cell samples via negative pressure created by a syringe. A thin 25 G needle (outer diameter 0.50 mm, length 25 mm) is introduced into the lesion with one hand. The cells are detached by the cutting edge of the needle and are conducted into the lumen by capillary force. The needle is removed and the cellular material is expelled onto a glass slide, spread, and immediately fixed. ⋯ Fine needle capillary technique offers several advantages. Without aspiration trauma to cells and tissues is reduced. Less blood in the samples results in higher quality of the cytological smear. These circumstances make it easier for the pathologist to comment the cytological findings. The handling of the needle is practiced with a wrist movement and not from the shoulder joint as in aspiration method using the Cameco syringe holder. This allows for a more sensitive puncture technique touching the lesion during sampling with the finger tips. The puncture causes less pain than the aspiration technique. Our results demonstrate that fine needle capillary technique is the better method of fine needle biopsy in the head and neck region.

Case Reports[Toxic inner ear damage in topical treatment of psoriasis with salicylates].
Whereas cochlear impairment after intravenous ingestions of salicylates is well known, reports of cochlear symptoms after topical application are quite rare. The extent of the ototoxic salicylate impact is increased by diabetes, renal insufficiency, and alcoholism. ⋯ Audiologic controls should be carried out during extended local application of salicylate containing ointment.

Case Reports[Chondroma of the petrous bone. A contribution to differential skull base tumor diagnosis].
Cartilaginous tumors of the mid-face and the skull base are rare. ⋯ Even the rare diagnosis of a chondroma should be considered for a differential diagnosis of skull base tumors.
