[Comparison of results obtained by laser and conventional instrumentation in vocal surgery. Pseudomyxoma and 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.

[Laser and phonosurgery (author's transl)].

Six patients are presented as examples of investigation and treatment of dysphonic patients in the ENT Department of the Tenon hospital, Paris. Investigations include photography, recording and sometimes sonograms before and after treatment. The multiplication of similar records will eventually show whether laser surgery should be preferred to instrumental surgery.

[Deep papillomatosis of the adult and laser (author's transl)].

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.
