ABSTRACT
Since 1979, we have treated patients suffering from bilateral vocal cord paralysis with laterofixation of one vocal cord, a simple and comparatively atraumatic method. To evaluate the long-term results of this method of laterofixation, 11 consecutive patients were examined at least 5 years postoperatively regarding breathing capacity, voice function, and swallowing ability. Breathing capacity was assessed by determination of orolaryngeal (upper) airway resistance and spirometry. Voice function was judged by two listening panels. Swallowing ability was studied by barium contrast radiography. Postoperative improvement of breathing capacity was, in most cases, found to be long lasting. Furthermore, there was no deterioration of voice function, nor were there aspiration problems during the postoperative follow-up period. We suggest this method of laterofixation as the treatment of choice in patients suffering from breathing difficulties due to bilateral vocal cord paralysis.

In some cases of extensive palatal defects surgical closure may be regarded as unfeasible, and the condition treated with an obturator prosthesis. In such a case the cleft can be closed in one operation by means of a pharyngeal flap elongated through a pharyngotomy according to Bengt Johanson (1966). Eleven patients who had used obturators were operated on between 1957 and 1978. The mean age of the patients was 39 years. All patients were cleft lip and palate or cleft palate cases; two unilateral, five bilateral, and four with an isolated cleft palate. In most of these patients a temporary tracheostomy was performed after which the pharynx was opened through a neck incision. A flap was created which reached the alveolar ridge. For oral closure, mucoperiosteal flaps were used. Anterior palatal fistulas developed in two cases; one closed spontaneously and the other remained as a 3-mm fistula behind the alveolar ridge. Three patients had postoperative transient dysphagia. Phoniatric evaluation showed that two patients had better speech after operation than before with an obturator. Gross speech improvement at this late age should not be expected and is not the primary goal of the procedure. The aim of surgical closure with an elongated pharyngeal flap is to replace the obturator.

Respiratory effects of injection of teflon were studied in twelve patients with unilateral vocal cord paralysis by determination of the orolaryngeal airway resistance (Rol). Ordinary spirometry and flow volume loops were also performed but were found to be less adequate than determination of Rol. Within the first week postoperatively, Rol increased by on average about 75%. Only one patient had clinical symptoms of laryngeal obstruction. One month after the injection of teflon, Rol was in all patients the same as preoperatively. It is concluded that teflon injection should be used with caution in patients with severe respiratory impairment but could be used without fear of induced future respiratory effects in patients with progressive pulmonary disease.

To reduce the laryngeal obstruction in bilateral vocal cord paralysis, a new method of laterofixation was developed. The method is technically simple and less traumatic than previously published methods. No peroperative tracheostomy is needed. During surgery two needles are inserted through the thyroid cartilage. A nylon thread is passed through the needles and the needles are then withdrawn. The thread thus forms a permanent loop around the vocal cord. The effects of the laterofixation on breathing and on the voice are documented by assessment of upper airway resistance and by two listening panels respectively. Thirteen patients have been operated upon so far. In most cases the breathing was improved and the influence on the voice was moderate and adjustable. If needed the possibility to perform a more extensive surgical procedure still remains. We suggest our method of laterofixation to be the first treatment of choice in patients suffering from bilateral vocal cord paralysis.
