[A prospective study on temporary and permanent sensation disorders after oral surgical measures in the lateral mandibular area].

Postoperative disturbances of sensory nerve function after dentoalveolar surgery imply forensic problems. Also the indication of microsurgical reconstruction will be discussed in these cases as well. Both questions can only be seen on the background of data material concerning those nerve complications. Therefore a clinical prospective study on functional disturbances of the inferior alveolar as well as the lingual nerve after dentoalveolar surgery in 1.107 cases was undertaken. Concerning the inferior alveolar nerve 2.2% of temporary functional disturbances were assessed while 1.4% of temporary functional disturbances for lingual nerve were found. Complete restoration of sensory function was found three months postoperatively in 20% of these cases and six months postoperatively in the remaining patients.

[Characterization of sensation disorders and neuropathic pain related to syringomyelia. A prospective study].

The present prospective study aimed to perform quantitative sensory testing (QST) in patients with painful or painless syringomyelia before and after surgical treatment of their syrinx (at 3 and 9 months). Eighteen consecutive patients with cervical or dorso-lumbar syringomyelia completed the study and 9 underwent surgery. Twelve patients had central neuropathic pain (of whom 6 were followed up). Spontaneous pain and brush-evoked allodynia were assessed. Von Frey hairs, vibrameter and a thermotest device were used to determine the mechanical-, vibratory-, thermal-detection thresholds, and the mechanical and thermal pain thresholds. Results showed evidence of deficits in temperature and pain sensibility in 17 cases, often associated with deficits in vibration and touch sensitivity (11 cases). Magnetic resonance scan, including axial images, demonstrated good correlation between paramedian extension of the syrinx and the laterality of thermal deficits. Somatosensory evoked potentials (11 patients) were abnormal in 9 cases at level, and showed good correlation with deficits in vibration. The magnitude of the thermal and tactile deficit was similar between areas of spontaneous pain and adjacent non painful areas. Surgery induced a significant decrease of tactile deficits, and to a lesser extent, of thermal deficits. Effects on neuropathic pain were positive in 3 patients (total disappearance of pain) and negligible or negative in 3 patients, despite collapse of the syrinx (in 2 cases). These results confirm that QST are useful in clinical practice to quantify the clinical results of surgery in patients with syringomyelia, and allow some hypotheses about the mechanisms of neuropathic pain in these patients.

[Sensation disorders and pain in spinal cord lesions].

In addition to the well known paraplegia or tetraplegia, lesions of the spinal cord frequently cause a series of disturbances of sensation in the segments around or distal to the lesion. Disturbances of sensation in spinal cord lesions are painful or non-painful. The painful and also the non-painful sensations may represent irritative and withdrawal phenomena. A series of central neurogenic pains seem to be best explained by spontaneous neuronal activity in sensory spinal cord neurones which have lost the peripheral, segmental and descending neuronal control from the nervous system. Surgical treatment of pain in cases of spinal cord lesions is rarely considered apart from root-avulsion where surgical lesion in the superficial part of the posterior horn is effective. No specific treatment is as yet available for pain and disturbances of sensation in cases of spinal cord injury. However, on the basis of our limited knowledge of the pathogenesis of these symptoms, future therapeutic strategy will be directed towards not only the peripheral but also the central points of attack. Treatment of painful conditions in patients with spinal cord injuries, as in other states of chronic pain, should also include social and psychological support.

[Incidence, risk factors and follow-up of sensation disorders after surgical wisdom tooth removal. Study of 1,106 cases].

A study was carried out to determine the risk of dysesthesia of the inferior alveolar and of the lingual nerve after molar surgery. A total of 1103 impacted lower wisdom teeth and 3 impacted lower second molars were removed in 687 patients, all of whom with unaltered sensibility preoperatively. Clinical, radiological, and surgical factors of each case were recorded. Postoperative disturbances in the sensibility of the lip and tongue were evaluated by neurological examination. Follow-up was carried out for a maximum of 35 weeks. Dysesthesia of the inferior alveolar nerve occurred with an incidence of 3.57%. The lingual nerve was injured in 2.1% of patients. Most of the initially reported alterations in sensation resolved within the follow-up period. Dysesthesia of the inferior alveolar nerve persisted in 0.91%, and of the lingual nerve in 0.37%. However, the extent of the prolonged impairment was slight in general. The effect of the documented factors on the incidence of dysesthesia was analyzed. For the inferior alveolar nerve, analysis revealed significant effects in older patients, for completely developed roots, for deeply impacted teeth, in the radiological relationship of the roots and the inferior alveolar canal, for difficult surgery, and for intraoperative exposure of the nerve. The surgeon and the anesthesia had a significant influence on lingual dysesthesia.
