Maturation of near-field and far-field somatosensory evoked potentials after median nerve stimulation in children under 4 years of age
2000
Abstract Objectives : The maturation of subcortical SEPs in young children. Methods : Median nerve SEPs were recorded during sleep in 42 subjects aged 0–48 months. Active electrodes were at the ipsilateral Erb's point, the lower and upper dorsal neck, and the frontal and contralateral centroparietal scalp; reference electrodes were at the contralateral Erb's point, the ipsilateral earlobe and the frontal scalp; bandpass was 10–3000 Hz. The peaks were labelled by their latencies in adults. Results : The peak latencies of N9 (brachial plexus potential) decreased exponentially with age during the first year, but increased with height thereafter. The interpeak latencies (IPLs) N9–N11, which mea…
Scalp, earlobe and nasopharyngeal recordings of the median nerve somatosensory evoked P14 potential in coma and brain death
1996
Median nerve somatosensory evoked potentials (SEPs) were recorded in a total of 181 patients in coma and brain death. Special attention was paid to derivation of P14 (the positive potential occurring approximately 14 ms after median nerve stimulation) with different electrode montages, using midfrontal scalp (Fz), linked earlobe (A1/2), median nasopharyngeal (Pgz) and non-cephalic reference (NC) electrodes. The P14 amplitude (and, to a lesser extent, latency) were invariably lower in brain death than in coma. The potential was preserved in coma in all patients, but lost in brain death in 9.8% in Fz-NC and Pgz-NC recordings, in 23.2% in Fz-A1/2, and in 100% in Fz-Pgz. Thus, Fz-Pgz was the de…
Radiofrequency tissue volume reduction for treatment of auricle keloids
2010
Objectives/Hypothesis: Keloids are often refractive to treatment, and recurrences occur quite frequently. Radiofrequency tissue volume reduction (RFTVR) is a surgical technology that induces extensive fibrosis at the target tissues. Methods: We applied RFTVR in 14 patients (19 auricles, 5 patients treated bilaterally; 9 female, 5 male; range, 10–66 years) with keloids of the auricle. Keloids were located at the earlobe in 4 patients (5 auricles), helix in 9 patients (12 auricles), and at both earlobe and helix in 1 patient (2 auricles). In 6 patients (8 auricles) RFTVR was the sole treatment modality applied, and in 7 patients (10 auricles) intralesional steroid injection was also performed…
Complications after superficial parotidectomy for pleomorphic adenoma
2018
Background The significance of complications after superficial parotidectomy remains unclear, since prospective studies are lacking. The aim of this study was to evaluate facial nerve dysfunction and other postoperative complications after superficial parotidectomy for pleomorphic adenoma of the superficial lobe and to identify the associated risk factors. Material and Methods Prospective and descriptive clinical study on 79 patients undergoing formal superficial parotidectomy with the modified facelift incision, dissection of the facial nerve and reconstruction with the superficial musculoaponeurotic system flap. Function of the facial nerve using the House-Brackmann scale and the intra- a…
Red ear syndrome in children: Review of literature and report of three cases
2020
Abstract Background Red ear syndrome (RES) is a neurological syndrome that is characterized by attacks of redness and pain that is localized in the earlobe, accompanied by a burning sensation, swelling or otalgia. The exact pathophysiology of RES is not known. Several pediatric cases have been described. They show an extreme variability in clinical presentation and therapeutic response, and therefore there are numerous difficulties in the diagnostic-therapeutic approach and in the comprehension of the physiopathology. The goal of this report is to present three clinical cases of red ear syndrome in children. These cases show various characteristics that can give useful indications regarding…
Nonsurgical treatment of earlobe aging in Mowlavi stages I and II earlobe ptosis with Hyaluronic acid fillers.
2018
Background: Earlobe deflation caused by fat atrophy is normally treated with lipofilling, mostly in the context of facelift surgery. In this report, we aim at reporting on Hyaluronic Acid injections to treat earlobe deflation. Materials and Methods: 16 Mowlavi Grade I and II patients were treated with HA injections, followed by molding to shape the lobule. Results: Effective correction, lasting 14 months on average, is achieved. Five patients needed a touch-up procedure after 4-6 months to improve the result. Conclusions: Earlobe augmentation with HA is an ideal option for correction of earlobe atrophy in cases of Mowlavi Grades I and II ptosis. Long-lasting (about 14 months) correction is …
Somatosensory evoked potentials after posterior tibial nerve stimulation — normative data in children
2000
We report normative data of somatosensory evoked potentials to posterior tibial nerve stimulation from 47 children 4–15 years of age. We recorded near-field potentials from the peripheral nerve, the cauda equina, the lumbar spinal cord and the somatosensory cortex. Far-field potentials were recorded from the scalp electrodes with a reference at Erb's point and on the earlobe. The near-field potentials N8 (peripheral nerve) and P40 (cortex) were present in all children. N20 (near-field from the cauda equina) was recorded in 38 subjects. N22 (near-field from the lumbar spinal cord), P30 and N37 ( both farfield waveforms probably generated in the brainstem) were recorded in 46 subjects each. T…
