A prospective, quantitative study on the clinical outcome of lingual nerve repair.

We previously showed in laboratory studies that the most effective method for repair of damaged lingual nerves was by excision of the neuroma, mobilization of the stumps, and direct reapposition with epineurial sutures. We have now undertaken a prospective study in a series of 53 patients treated by this method and have evaluated the outcome by quantifying and comparing the results of tests of sensation before and after operation. The outcome in individual patients was variable. However, pooled data from all patients showed a highly significant improvement in sensation at the final assessment 12 months or more after the repair. The proportion of patients who responded to most or all light touch stimuli increased from 0% to 51% after repair, and the proportion who responded to pin-prick stimuli increased from 34% to 77%. There was no correlation between the final results of any of the tests and the delay before repair. None of the patients regained completely normal sensation and there was no reduction in the number with spontaneous paraesthesia or pain. However, fewer patients tended to bite the tongue by accident and most of them considered the operation worthwhile. These data show that lingual nerve repair is effective in most patients and we suggest that it should be offered to all those who show few signs of spontaneous recovery after injury.

[Functional craniomandibular disorders and ENT-symptoms].

Complaints in the otolaryngologic region, that cannot be referred to an otolaryngological pathologic process, are often caused by or combined with craniomandibular dysfunctions. As a rule these complaints are not the result of direct mechanical irritation of the articular tissues, but the effect of neuromuscular incoordination and spasms. Consequently the term "Costen's syndrome" is obsolete and should be used no more. In many cases the interaction of otolaryngological symptoms and craniomandibular disorders can only be proved ex iuvantibus. Occlusal equilibration combined with physical and physiotherapeutic treatment are approved methods to normalize neuromuscular function and eliminate muscle tension and pain.

The head and neck radiotherapy patient: Part 1--Oral manifestations of radiation therapy.

The incidence of head and neck cancer increases annually in the United States, and radiation therapy is frequently a primary or adjunctive mode of therapy. As the number of radiotherapy patients rises, the need for proper detection, diagnosis, and treatment of oral lesions likewise increases. Depending on tumor site and size, radiation dosage, and preexisting oral conditions, a variety of oral radiation side effects may be present. These range from mild and reversible changes to severe and potentially disfiguring or life-threatening alterations. This article, in two parts, will review the oral manifestations of cancer radiation therapy and appropriate management techniques.

Smell and other sensory disturbances in migraine.

Osmophobia or hyperosmia featured in 25 of 50 migraineurs during the headache phase of their attacks. Pleasant or unpleasant odours could precipitate migraines in 11 patients in this series. Other sensory disturbances and precipitants were also studied. Neurological precipitation of attacks provides further support for a primary neural rather than a vascular pathogenesis of migraine.
