The relief of snoring by nasal surgery.

Patients with nasal obstruction may also complain of snoring. It is uncertain whether surgery which relieves the nasal obstruction will also relieve the snoring. We have reviewed 126 patients who complained of both nasal obstruction and snoring and who underwent nasal surgery. Snoring was completely relieved in 39 patients (31%), was less loud in a further 72 patients (57%), unchanged in 11 and louder in 4. It occurred on fewer nights post-operatively in 61, on the same number in 24 and more frequently in 2. Patients who had nasal polypectomy as part of their nasal surgery obtained the greatest snoring relief. This study suggests that when snoring and nasal obstruction coexist nasal surgery should be considered as the first line of surgical treatment.

The applied anatomy of thyroglossal tract remnants.

Recurrences after surgery for thyroglossal cysts and fistulas were common until, in 1920, Sistrunk described his technique for removing the whole thyroglossal tract. Since that time there has been considerable argument concerning the exact path taken by the tract particularly in relation to the hyoid bone. In an attempt to elucidate this problem, studies have been made of embryos at varying stages of development, of serially step-sectioned adult larynges and of surgical specimens. These studies suggest that the thyroglossal tract occupies a constant and embryologically predictable position in relation to the hyoid bone and they support the rationale of Sistrunk's procedure.

Changes in nystagmus on raising body temperature in clinically suspected and proved multiple sclerosis.

Electronystagmography was used to record the appearance or alteration of nystagmus after raising the body temperature by a heat cradle. Nystagmus was increased or provoked in 13 out of 15 patients with clinically proved multiple sclerosis, in eight out of 12 suspected cases, but in no normal controls. No positive results were obtained in 12 patients with other neurological diseases, even when nystagmus was part of the clinical picutre. The technique is simple to use and may have a role in the diagnosis of multiple sclerosis.

Recurrent laryngeal nerve palsy and endotracheal intubation.

Voice changes developing after endotracheal intubation have been found to be due to a recurrent laryngeal nerve palsy in four patients. In none of these patients was there any obvious cause and this posed the question whether endotracheal intubation itself could result in a paralysis of the nerve. Cadaver dissection has suggested a way in which which paralysis could occur and this and other possible aetiologies are discussed.
