Neurilemmoma is a benign tumor that originates from the Schwann cell. It frequently occurs in head and neck regions, but neurilemmoma of external auditory canal is extremely rare. Here, we report a very rare case of 36-year-old male with a tumor located in the posterior wall of external auditory canal, preoperatively suspected as neurilemmoma originated from Arnold's nerve by temporal bone magnetic resonance imaging. The tumor mass was surgically excised and pathologically confirmed as a neurilemmoma.

Spinal block procedures are useful methods that reduce the need for surgical treatment. In addition to their therapeutic aspects of pain relief, in many patients, they are also used for diagnostic purposes to distinguish from symptoms originating from extra-spinal areas. Therefore, these procedures are the most basic technique for orthopedic surgeons dealing with diseases from limbs and spine. On the other hand, despite the simplicity of the instruments and drugs used, the overall understanding of them and the lack of knowledge of the possible side effects and complications can cause serious harm to the patient at the beginning of the trial. Therefore, it is necessary to understand the types of drugs used in the spinal block procedures, pharmacokinetic properties, and the side effects of each drug. In addition, efforts should be made to identify their indications, as well as advantages and disadvantages of each procedure to avoid possible complications. The purpose of this review was to provide basic knowledge and skills necessary for lumbar spinal block procedures as well as provide the reader with the ability to perform themselves.

Compressive neuropathy in the upper extremity can be clinically diagnosed by careful history taking, physical examination of the involved nerve. Electrodiagnosis for the suspected nerve informs severity of compression of the involved nerve and indicates specific site of the lesion. In the early stage of the disease, non-operative treatment generally cures the symptom, however, if the conservative treatment fails, confirmation of the exact site of the lesion should be preceded before the operation. Recently, ultrasonography, as a supportive tool for the diagnosis of compressive neuropathy has increasing popularity for its ability to find space occupying lesion, anatomical change of the nerve, and the pathologic change in the nerve itself. For the successful treatment of the compressive neuropathy, these various diagnostic tools have to be introduced in the orthopaedic clinic.
