  • Influence of age and gender on the jaw-stretch and blink reflexes
    Experimental brain research, 2006
    Co-Authors: Anitha Peddireddy, Kelun Wang, Peter Svensson, Lars Arendt-nielsen
    Abstract:

    The aim of this study is to investigate the influence of age and gender on jaw-stretch and blink reflexes (BR). Thirty “young” (26.5±0.7 years) and thirty “old” (47.8±1.8 years) healthy adults were included. Short-latency stretch reflex responses were evoked in the masseter and temporalis muscles by fast jaw-stretches, and BR in orbicularis oculi muscle were evoked by painful electrical pulses (0.5 ms duration), delivered by a concentric electrode placed on the left lower forehead close to the Supraorbital Foramen. For the jaw-stretch reflex, the pre-stimulus EMG activity in the old subjects was significantly lower than that of the young subjects in the right and left masseter and temporalis muscles (P

For the jaw-stretch reflex, the pre-stimulus EMG activity in the old subjects was significantly lower than that of the young subjects in the right and left masseter and temporalis muscles ( P< 0.006), whereas there was no difference in the results between males and females.

  • Effect of experimental posterior temporalis muscle pain on human brainstem reflexes
    Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology, 2005
    Co-Authors: Anitha Peddireddy, Kelun Wang, Peter Svensson, Lars Arendt-nielsen
    Abstract:

    Abstract Objective To study the modulation of jaw-stretch and blink reflexes by experimental posterior temporalis muscle pain. Methods Thirty healthy volunteers (15 males, 25.5±0.6 years and 15 females, 27.4±1.2 years) were included. Short-latency stretch reflex responses were evoked in the masseter and temporalis muscles by fast stretches (1mm displacement, 10ms ramp time) and the blink reflexes were evoked by painful electrical pulses (0.5ms duration), delivered by a concentric electrode placed on the left lower forehead close to the Supraorbital Foramen before, during and 15min after a period with experimentally induced muscle pain. Results The normalized peak-to-peak amplitude of the stretch reflex in the painful temporalis was significantly higher during pain in both males and females compared with pre- and post-pain conditions ( P P Conclusions The present results indicated that experimental posterior temporalis muscle pain facilitates the jaw-stretch reflex, whereas the nociceptive specific blink reflex is inhibited. Significance Present study suggested that these reflexes are suitable models for probing pontine and medullary pain processing.

    Abstract:

    The purpose of the current study was to determine the Supraorbital Foramen (SOF) and infraorbital Foramen (IOF) based on soft tissue landmarks, to facilitate prediction of the location of this structure during facial surgery. Forty-two hemispheres of 21 adult cadavers (16 men and 5 women; aged 30-75 years) were dissected to expose the SOF and IOF. The locations of the SOF and IOF were evaluated with direct and photographic measurements. The data gained were analyzed by statistical method. The SOF localized 23.11 ± 2.35 mm superior and 9.48 ± 3.06 mm lateral to the angulus oculi medialis (AOM). The vertical angle from AOM to SOF was 68.3 (SD, 6.44) degrees. The SOF localized 24.81 (SD, 3.39) mm inferior and 10.89 (SD, 2.78) mm lateral to the AOM on the front view. The vertical angle from AOM to IOF was 66.5 (SD, 5.18) degrees. The SOF localized 11.22 (SD, 2.01) mm inferior and 6.09 (SD, 2.32) mm lateral to the ala of the nose (AL) on the front view. The vertical angle from AL to IOF was 61.7 (SD, 7.61) degrees. These results were a little different from the results of some other populations. We found the IOFs located on the point of one-fifth proportion distant to the ALs along the vertical direction distance from AL to SOF, whereas the AOMs located on the point of three-fifths proportion distant from the AL. Our results may provide more detailed information to predict the location of the SOFs and IOFs and help to prevent nerve or vessel damage.

    The Journal of craniofacial surgery, 2011
    Co-Authors: Dao Ning Liu, Jing Li Guo, Qi Luo, Yong Tian, Chang Li Xia
    Abstract:

    The purpose of the present study was to determine the locations of the Supraorbital Foramen (SOF) and the infraorbital Foramen (IOF) relative to soft- and hard-tissue landmarks. It will provide more accurate data for dental and facial surgery. Twenty embalmed adult cadavers (40 sides; 16 men, 4 women) were dissected to expose the SOFs and IOFs, and another 46 skulls (92 sides) were also measured for further study. The locations of the SOFs and IOFs were evaluated with direct and photographic measurements. The data gained were analyzed by statistical method. The horizontal distances between the SOFs/IOFs and the medial canthus to the distance between the medial canthus and the lateral canthus ratios have been measured, and their confidence intervals are 0.22 to 0.31 and 0.34 to 0.49, respectively, and their linear regression equations are EF = 0.58 CF + 25.02 (unit: mm) and EF = 0.51 DG + 24.20 (unit: mm). The vertical distance between IOFs/SOFs and the medial/lateral canthi are 25.09 ± 3.36 mm/23.91 ± 3.31 mm and 25.75 ± 3.34 mm/26.93 ± 3.88 mm, respectively. The horizontal angle between IOFs/SOFs and the medial/lateral canthi are 72.54 ± 7.13 degrees, 66.77 ± 5.17 degrees, 47.45 ± 6.57 degrees, 54.69 ± 8.38 degrees, respectively. Based on the hard tissues, The SOF localized 20.55 ± 3.24 mm medial and 13.78 ± 2.60 mm superior to the zygomaticofrontal suture. And the horizontal angle between them is 56.04 ± 6.87 degrees. The IOF localized 18.52 ± 2.30 mm medial and 30.79 ± 3.29 inferior to the zygomaticofrontal suture. The horizontal angle between them is 31.06 ± 4.33 degrees. We also found that most (96.81%) of the IOFs were located below the middle line of the zygomatic arch. These results may provide more detailed information about the locations of SOF and IOF. And they will facilitate prediction of the locations of IOF and SOF in clinical procedure.
