[Laser surgery in otorhinolaryngologic diseases].

This survey is based on our own experiences and a study of the literature. The CO2 laser has certain advantages in the surgical treatment of otosclerosis, both in the primary operation and in reoperation. In rhinal surgery the argon laser has been used with good results in Osler's disease. Laser surgery is not recommended for vasomotoric rhinitis and polyposis. The CO2 laser has improved the quality of treatment of laryngeal papilloma. With high precision and minimal bleeding the postoperative voice is better than with conventional surgery. The CO2 laser can also be used to exstirpate small malignant tumours of the tongue and leukoplasia of the oral mucosa. Healing is rapid and involves relatively little pain. The postoperative functional result is usually good, due to moderate formation of scars.

[Thyroid carcinoma and the recurrent nerve. Recurrence fall-out, incidence and causal circumstances in a large case-load of patients with thyroid carcinoma].

Impairment of vocal cord function is a threat to patients with thyroid carcinoma; either due to the tumor having infiltrated the larynx or the recurrent nerve, or to accidental damage to the laryngeal nerves during thyroid surgery. We have reviewed 1,245 patients' records which were filed under the diagnosis of thyroid carcinoma at Det Norske Radiumhospital from 1956 to 1978. Pareses of vocal cords were noted in 465 patients (37.3%) during the course of their illness. In 135 patients (10.8%) the pareses were due to infiltration by the tumor, most commonly seen in anaplastic carcinoma. In 267 patients (21.4%) the pareses followed surgery; planned resections of the recurrent nerves were performed in 48 patients (3.9%). Transient pareses with normal vocal cord movements within months were experienced in 137 cases (11%). Permanent paralysis caused accidentally during surgery was seen in 82 patients, representing 6.6% of all patients and 4.7% of the surgically exposed nerves. We stress the need for pre- and postoperative evaluation of vocal cord movement as an aid to future diagnosis and optimal surgical planning.

Transitory IgA-deficiency, persistent IgE deficiency and recurrent respiratory tract infectious disease after splenectomy.

In a 14 year old boy, a ruptured spleen was removed. Two months after the splenectomy he developed recurrent infections of the respiratory tract. A deficiency of IgA and IgE in his blood serum was found. His impaired resistance to respiratory tract infections responded well to substitution therapy with IgA. Spontaneous clinical recovery occurred during 3 years after the splenectomy, and was parallelled by a slow return of IgA to normal levels, whereas the absence of IgE persisted. The identical twin brother of the patient, who had his spleen intact, had normal levels of serum IgA and did not suffer from frequent respiratory tract inflammations.
