[Laryngeal immobility after thyroidectomy].

One of the most common complications of surgery of the thyroid gland is vocal folds immobility. New advances in its management have been achieved over the last few years. Laryngeal electromyography, stroboscopy, and computerized analysis of the voice help guide diagnosis, allowing differentiation between recurrent nerve paralysis and glottis traumatism due to intubation, and further follow-up of recovery with relevant therapeutic decisions. In case of unilateral vocal fold paralysis, intrafold silicone or injection of autologous fat is more and more routinely used to obtain vocal rehabilitation. In case of bilateral vocal fold paralysis, to avoid tracheotomy, partial posterior cordectomy using laser surgery restores sufficient laryngeal airflow, with minimal vocal sequelae. Early management of these complications by teams of specialists should allow appropriate and less invasive surgery.

[Photochemotherapy in the treatment of carcinoma of the vocal cords of early stage (Tis, T1)].

Photodynamic Therapy (PDT) is a treatment which can prove interesting in head and neck oncology for small squamous cell carcinomas. We studied 33 patients with vocal cord squamous cell carcinoma at an early stage who have been treated by Photodynamic Therapy from 1986 to 1992. We used a Dye Laser Aurora which produces light with a wavelength of 630 nm. The intervention was done under general anesthesia, 72 hours after the injection of hematoporphyrin derivative. The mean and the maximum follow-up was respectively 66 and 93 months. The local control after an exclusive PDT was 73% at 3 years, 5 years, 7 years. If this method fails, a conventional treatment may be used.

[Attic emptying in cholesteatoma and precholesteatoma states. Technique, indications and results].

A surgical procedure different from the open or closed technique is presented. The attic is emptied through the meatus after a retromeatal access to the antromastoidal cavities. By blocking the aditus ad antrum, the procedure produces an antrio-attic microcavity with no recessus. Results of resection of epidermal lesions are quite satisfactory with a low rate of residual pathology. Retraction pouches do not develop because the mastoid is excluded and no attic recessus is formed. Surveillance of the cavity is easy and the disadvantages of functional sequellae inherent in open techniques are avoided. The preliminary results would confirmed the quality of the procedure. In 22 cases, there were 3 residual perles on the windows and 2 retraction pouches (anterior and posterosuperior). This technique is indicated in precholesteatoma states with poor prognosis and cholesteatomas of the attic. For more advanced lesions, this technique is less reliable and the open procedure is required.

[Laser CO2 arytenoidectomy by endoscopic approach in bilateral laryngeal paralysis. Apropos of 45 cases].

Between 1980 and 1993, 45 patients with bilateral cord abductor paralysis were treated by carbon dioxide endoscopic laser arytenoidectomy. Thyroid surgery was the main cause of bilateral laryngeal palsy (67%). Seven patients, who were tracheotomised before treatment, were decanulated. Ninety-one percent of the patients recovered physiologic respiration. The follow up period lasted from one month to thirteen one-half years. Advantages and disadvantages of laser arytenoidectomy are compared with other techniques.
