Cerebrospinal fluid leak
Surgical procedures have long and possibly daunting names. The meaning of many surgical procedure names can often be understood if the name is broken into parts. For example in splenectomy, "ectomy" is a suffix meaning the removal of a part of the body. "Splene-" means spleen. Thus, splenectomy refers to the surgical removal of the spleen (or sections thereof). "otomy" means to cut into a part of the body; a splenotomy would be to cut into, but not necessarily remove, the spleen.
The field of minimally invasive surgery has spawned another set of words, such as arthroscopic or laparoscopic surgery. These take the same form as above; an arthroscope is a device which allows the inside of the joint to be seen.
A cerebrospinal fluid leak (CSFL) is a medical condition when the cerebrospinal fluid of a person leaks out of the dura mater. This can be caused by several reasons, including spontaneous cerebrospinal fluid leak, post-surgical lumbar puncture (iatrogenic), physical trauma, etc. While high CSF pressure can make reclining unbearable, low CSF pressure due to a leak is often relieved somewhat by maintaining a supine position.
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain (the medulla oblongata specifically). The brain and spinal cord together make up the central nervous system (CNS). The spinal cord begins at the occipital bone and extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 1/2 inch thick in the cervical and lumbar regions to 1/4 inch thick in the thoracic area. The enclosing bony vertebral column protects the relatively shorter spinal cord. The spinal cord functions primarily in the transmission of neural signals between the brain and the rest of the body but also contains neural circuits that can independently control numerous reflexes and central pattern generators. The spinal cord has three major functions: as a conduit for motor information, which travels down the spinal cord, as a conduit for sensory information in the reverse direction, and finally as a center for coordinating certain reflexes.
The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The length of the spinal cord is much shorter than the length of the bony spinal column. The human spinal cord extends from the foramen magnum and continues through to the conus medullaris near the second lumbar vertebra, terminating in a fibrous extension known as the filum terminale.

Tympanocentesis is the drainage of fluid from the middle ear by using a small-gauge needle to puncture the tympanic membrane, also known as the eardrum.
It is sometimes referred to as a "tap" and, when conducted twice as part of a clinical trial of medication, a "double tap."
