![]() These cysts contain fluid, cholesterol, and other lipids. Cholesterol granuloma : A rare, benign cyst can occur in the petrous apex, a section of skull bone near the middle ear.TEES can often be used to treat early cholesteatomas with superior visualization, no incision behind the ear, and quicker recovery. Cholesteatomas can be congenital or result from an ear injury or repeated ear infections. Cholesteatoma: A benign skin cyst, made up of skin and dead skin cells, can develop in the middle ear.Such CSF leaks can be congenital defects present since birth or acquired leaks that result from trauma, surgery, infection, or spontaneously. CSF leaks that cause symptoms in the ears typically occur in the temporal bone at the sides and base of the skull. Cerebrospinal fluid (CSF) leak : The fluid that surrounds and protects the brain and spinal cord can leak through a hole in the meninges, the membrane that surrounds the brain. ![]() TEES can be used in selective cases to remove acoustic neuromas. Acoustic neuroma : Also called vestibular schwannoma, this noncancerous tumor grows on the vestibular nerve leading from the inner ear to the brain.Our experienced specialists use TEES to treat children and adults with conditions such as: Cyst drainage: Drainage of cholesterol granulomas and other inner-ear cysts can, in many cases, be performed using TEES.Tympanoplasty: Repair of a perforated eardrum.Tumor removal: Removal of benign or malignant (cancerous) tumors such as acoustic neuromas or paragangliomas.Stapedectomy: Removal and replacement of the stapes bone to treat hearing loss caused by otosclerosis.Ossiculoplasty: Reconstruction of the ossicles by either reshaping the patient’s existing bones or implanting a titanium prosthesis, to help restore hearing.Our experienced surgeons perform several procedures using endoscopic ear surgery, such as: In traditional ear surgery with a microscope, surgeons have only a straight-line field of view, which limits the ability to see all areas for proper treatment. Better view of the treatment area: An endoscope provides a wide field of view, allowing surgeons to see into tiny recesses within the middle ear.Avoiding an incision can help reduce patients’ pain as they recover. Using the endoscope to visualize the surgical area, the surgeon uses tiny instruments to perform the operation. No visible incision: The surgeon inserts an endoscope (very thin tube tipped with a light) through the patient’s ear into the ear canal to access the middle ear.Endoscopic ear surgery offers several benefits over traditional ear surgery, such as: Our skilled neurotologists perform TEES whenever possible to avoid the need for an incision behind the ear and an opening through skull bone. UT Southwestern is one of only a few centers in the country that offers TEES, and we’re the first to use the procedure for the removal of acoustic neuroma tumors. Our surgeons train neurotologists and otolaryngologists locally and around the world in the latest minimally invasive and open surgical procedures, and they also speak and present their research at both national and international conferences. Our highly skilled team is pioneering research on TEES to improve currently used techniques and to discover more ways to use the advantages of the procedure. We treat patients of all ages for hearing loss, balance problems, tumors, infections, injuries, congenital (present since birth) defects, and facial nerve disorders. The neurotologists in our Comprehensive Skull Base Program are specialists in medical and surgical care for disorders of the ear, cranial nerves, and the skull base. Surgery is often necessary to avoid complications such as hearing loss, facial paralysis, balance problems, or brain infections such as meningitis, which can be life-threatening. As these conditions progress, they can destroy nearby structures, such as the ear bones, facial nerve, and the inner ear. Most middle-ear conditions that we treat with TEES are not life-threatening, but they can greatly affect a person’s quality of life. This causes less pain and results in faster recovery. It differs from traditional ear surgery in that surgeons access the middle ear through the ear canal rather than through an incision behind the ear. Transcanal endoscopic ear surgery (TEES) is minimally invasive surgery to operate on tiny, delicate structures within the middle ear. Leading Expertise in Endoscopic Ear Surgery
