Landmark of Ultrasound-Guided Trigeminal Block: Lateral Pterygoid Muscle.

Lateral pterygoid muscle and maxillary artery are key anatomical landmarks for ultrasound-guided trigeminal nerve block.

The Effects of Ultrasound-guided and Anatomic landmark-based Superficial Cervical Plexus Block on Post-operative Pain Intensity in Thyroidectomy Patients: A Clinical Trial

Background and Objective: Pain is one of the most common complications after thyroidectomy. Opioid administration can overcome this complication, however, it has some side effects, including nausea and vomiting. So, the use of local anesthetic instead of opioids is a good alternative. This study was conducted to evaluate and compare the effect of ultrasound-guided superficial cervical plexus bl...

Treatment of great auricular neuralgia with real-time ultrasound-guided great auricular nerve block

RATIONALE The great auricular nerve can be damaged by the neck surgery, tumor, and long-time pressure on the neck. But, great auricular neuralgia is very rare condition. It was managed by several medication and landmark-based great auricular nerve block with poor prognosis. PATIENT CONCERNS A 25-year-old man presented with a pain in the left lateral neck and auricle. DIAGNOSIS He was diagno...

A cause of entrapment of the lingual nerve : ossified pterygospinous ligament – a case report

The pterygospinous ligament extends from the pterygospinous process of the lateral lamina of the pterygoid process of the sphenoid bone, coursing inferior level of the oval foramen, to the spine of sphenoid bone in the infratemporal fossa. The ossification of ligament forms the pterygospinous bony bridge and pterygospinous foramen (Figure 1). In existence of this case, branches of the mandibula...

Cadaveric validation of dry needle placement in the lateral pterygoid muscle.

OBJECTIVE The aim of this anatomical study was to determine if a needle is able to reach the lateral pterygoid muscle during the application of dry needling technique. METHODS A dry needling approach using 2 needles of 50 to 60 mm in length, one inserted over the zygomatic process posterior at the obituary arch (for the superior head) and other inserted below the zygomatic process between the...
