[Tumors and vascular malformations of the larynx. Angiographic aspects and therapeutic indications].

Satisfactory results were obtained in a case of laryngeal paraganglioma following surgery preceded by angiography and embolization. Clinical, arteriographic and histologic features of vascular malformations of the larynx are discussed, localized and isolated laryngeal angiomas being distinguished from those classified among cervicofacial angiodysplasias. Laryngeal vascular malformations are all capillarovenous angiomas. Treatment has been facilitated by the availability of arteriography and embolization methods, and consists of injections of a sclerosing agent (such as "ethybloc") together with surgery in some cases.

[Undifferentiated carcinoma with lymphoid stroma (undifferentiated carcinoma nasopharyngeal type?). Optical, electron microscopical and immunofluorescence study (author's transl)].

A case of undifferentiated carcinoma with lymphoid stroma of the paired gland is reported in a chinese woman with positive Epstein-Barr virus serology. The histologic appearance of the tumor is very similar to undifferentiated carcinomas nasopharyngeal type (UCNT). Ultrastructural study reveals features of epidermoid differentiation. Immunofluorescence study shows numerous and predominant IgA plasma cells in the stroma. The relationship between this tumor and the benign lymphoepithelial lesions of the salivary glands are discussed. The present case and the review of the literature emphasize the morphological and epidemiological similarities between UCNT and undifferentiated carcinoma with lymphoid stroma of the salivary glands.

[Acoustic variation after surgery for severe Bell's palsy].

Auditory thresholds were studied before and after surgical decompression of the facial nerve in 35 patients following either transmastoidal (20 cases) or transmastoidal and suprapetrosal (15 cases) operations. Seventeen of the patients were under 40 years of age at the time of surgery, which did not affect hearing in the opposite ear. However, auditory threshold levels fell in the operated ear. These were of the bone conduction type, and possessed characteristics of an acute hearing lesion (maximal in the 4000 frequency range and improving progressively) of 0 to 35 dB (mean 5 dB). Possible causes of the hearing loss are discussed.

[Hypoglossofacial anastomois. Analysis and results on 12 cases and comparison with results of facio facial anastomosis].

Regular facial clinical testing (G. Freyss) and surface integrated electromyography was employed to quantitatively assess the course of 12 hypoglossofacial anastomoses. Recovery was complete after an average period of 4 months, the time before conducting anastomosis (2 to 14 months after onset of facial paralysis) not affecting the quality of results obtained. Age significantly influenced recuperation of remaining tone, but this was always superior to 70 p. cent in relation to the other half of the face. Motor recovery was not affected by age, and was a mean of 51 p. cent after one year (50 to 70 p. cent when compared with the normal half of the face). Lingual sequelae were minimal, early physical therapy compensating for the inevitable resulting synkinesis. Results after hypoglossofacial anastomosis are compared with those obtained by faciofacial anastomoses (published in 1980). The former is a simpler and more rapid technique which produces more constant results and leads to earlier recovery (4 instead of 9 months after faciofacial anastomosis. Tone is also improved and motility satisfactory.

[Undifferentiated clear cell thyroid carcinoma. Diagnostic interest of ultrastructural study (author's transl)].

Optical and electron microscopy features of an undifferentiated clear cell carcinoma of the thyroid are presented. Tumor cells have irregular, often multiple nuclei, showing numerous mitosis. Diastase-digested P.A.S. positive material is demonstrated in their cytoplasm. Numerous lymphocytes and plasma cells are present in the stroma. Electron microscopy showed large cytoplasmic areas of monoparticular free glycogen, few lipid droplets, numerous desmosomes and some intercellular microvilli. Most cells contained varying amounts of tonofilament bundles suggesting a partial epidermoid differentiation. This atypical appearance has not been described in metastases from clear cel carcinoma of kidney and may assist the primary nature of undifferentiated clear cell thyroid carcinoma.

Skull base chondroma of extracranial origin.

METHODS: Two cases of chondroma at the skull base, most probably of extracranial origin, are presented: one at the apex of the petrous pyramid and the other in the infratemporal fossa. RESULTS: In the second case, the surgical findings suggested that the tumor originated in the cartilagineous part of the eustachian tube. The world literature was reviewed and only three cases of extracranial chondromas at the skull base, and ten cases of chondromas of the nasopharynx have been described so far. CONCLUSIONS: The potential origins of chondromas at the skull base are discussed: Cartilagineous remnants at the basisphenoid and basiocciput or the cartilagineous part of the eustachian tube seem to be the most probable origin.

Treatment of salivary stones by extracorporeal lithotripsy.

PURPOSE: This study was designed to evaluate the efficacy of extracorporeal lithotripsy (ECL) in the treatment of salivary stones. PATIENTS AND METHODS: In a prospective study, an additional 15 patients suffering from sialolithiasis were treated by applying extracorporeally generated shock waves. No patients needed general anaesthesia, sedatives, or analgesics. RESULTS: Treatment was effective in 80% of the 15 patients in this series (5 total efficacy and 7 partial efficacy). Only minor complications were observed. CONCLUSION: Lithotripsy is a promising nonsurgical therapy for the treatment of sialolithiasis.
