  • inferior
  • The position of the superior and inferior orbital fissures may still be identified posteriorly near the roof and floor of the orbit because of the nerves (22,23,24), blood vessels (20,26), smooth muscle (11) and fascia which have been retained. (stanford.edu)
  • technique
  • To develop an ultrasound-guided injection technique of the maxillary nerve in equine cadavers and to evaluate its efficacy and potential for complications in vivo . (wiley.com)
  • anatomical
  • The deep location and proximity of the nerve to surrounding vascular and orbital structures make an accurate, complication-free injection a challenge using traditional techniques reliant upon surface anatomical landmarks. (wiley.com)
  • The PSAA and PSAN cross a canal in the bony wall of the maxillary sinus, whose location has been previously described in scientific papers through various methodologies such as computed tomography (CT) studies on cadavers [ 7 - 10 ] and anatomical specimens [ 11 , 12 ]. (hindawi.com)
  • block
  • A modification of this regimen was subsequently used, incorporating the maxillary nerve block, and qualitative differences were then assessed retrospectively between the two regimens. (entjournal.com)
  • Twenty-five consecutive patients were retrospectively studied who underwent hybrid BSD procedures in the office setting using the maxillary nerve-block regimen modification. (entjournal.com)
  • Several qualitative differences were observed after modifying the patient-preparation regimen incorporating the maxillary nerve block. (entjournal.com)
  • This preliminary study provides support for use and further evaluation of the maxillary nerve block for in-office rhinologic procedures. (entjournal.com)
  • If the trend continues to rise in performing advanced in-office rhinologic procedures in selected patients, the maxillary nerve block may find a place in the patient-preparation protocol. (entjournal.com)
  • structures
  • An independent observer dissected the area and recorded the number of times that dye successfully contacted the nerve, along with inadvertent penetration of other structures. (wiley.com)
