Superficial Cervical Plexus block and Ultrasound-guided styloid process infiltration in Eagle Syndrome

Abstract

Summary Background: The dimensions of the styloid process (SP) coming from the temporal bone normally measure 2.5 cm in length. An elongated SP generates compressions on adjacent structures, developing unspecified presentation symptoms such as facial pain, sore throat, earache, dysphagia and headache among the most common, known as Eagle Syndrome (ES). When conservative management fails, intervention or surgical options are sought. Ultrasonography is an accessible, safe tool, avoids radiation, and is an effective technique that allows SP identification by guiding the application of local anesthesia (LA) and a steroid. We describe the case of a 45-year-old female patient with ES whose conservative treatment failed, and who was subsequently subjected to an SCPB and steroid injection, and LA in the SP USG-guided with adequate pain management. Likewise, ultrasound-guided (USG) superficial cervical plexus block (SCPB) is a suitable option, which involves its mastoid, auricular transverse, supraclavicular rami and its anastomotic rami. Case study: We describe the case of a 45-year-old female patient with ES whose conservative treatment failed, and who was subsequently subjected to an SCPB and steroid injection, and LA in the SP USG-guided with adequate pain management. Conclusions: USG-guided SCPB and SP infiltration is a treatment option for ES patients.
