[Trends in clinical research for one canal cochlear implantation]. / Orientations de recherche clinique en matière d'implantation mono-canale.

Like any modality of perception, the processes of hearing can be divided up into two levels: modular or primary, and symbolic or central. Multiple-canal implantation is rather applied to the former mechanism, single-canal implantation to the latter. A bank of electrical signals recognizable from each other is being built up. It may be utilized in single-canal systems using this vocabulary to form sentences. The proper phonetic feature to be matched will then have to be selected.

[Comparison of results obtained by laser and conventional instrumentation in vocal surgery. Pseudomyxoma and nodules]. / Comparaison des résultats obtenus par le laser et l'instrumentation conventionnelle en phonochirurgie. Pseudomyxomes et nodules.

Surgery for pseudomyxoma or laryngeal nodules should always be as conservative as possible. This is obtained both by the use of the laser and conventional surgical techniques, results being analogous from the phoniatric point of view. From the technical aspect, however, the laser is a much simpler procedure.

[Rheumatic syndromes with ENT symptoms (author's transl)]. / Syndromes rhumatismaux à manifestations O.R.L.

The authors present one case of systemic lupus erythematosus associated with paralysis of the larynx and spontaneous expulsion of the arytenoid cartilage followed by healing. Two cases of chronic atrophic polychondritis are also presented, and the diagnostic and therapeutic criteria of the disease are discussed.

[Deep papillomatosis of the adult and laser (author's transl)]. / Papillomatose profonde de l'adulte et laser.

Adult papillomatosis may be similar to child's papillomatosis or have an exophytic presentation. We describe a third kind of papillomatosis where papillomas tend to grow deep inside the mucosa. Laser seems an effective treatment of this condition which used to lead to tracheostomy and even total laryngectomy.

[Familial facial paralysis. Generalised cortical hyperostosis (author's transl)]. / Paralysies faciales familiales. Hyperostose corticale généralisée.

Generalised cortical hyperostosis is a rare disease. In our own field it involves the lower jaw and the skull. Certain nerves, including the facial, may be compressed as a result. This condition behaves genetically in a recessive or dominant manner.

[Jugulo-carotid glomus and false glomus tumors. Three cases (author's transl)]. / Glomus et faux glomus jugulo-carotidiens. A propos de trois cas.

A carotid glomus is, classically, a firm, non-pulsatile tumor situated just behind the carotid bifurcation. Erreurs are possible: -- the tumor may be pulsatile, -- the site impossible to define if the tumor is large. Carotid arteriography is essential, in the case of a glomus tumor showing widening of the carotid bifurcation. Treatment is surgical, with possible ablation or reconstruction of the carotid axis. Such surgery must be performed in a specialized centre.
