Team offers innovative proceed to provide patients with formidable temporal bone defects


Temple University Hospital is charity an innovative proceed to provide patients with formidable temporal bone defects, including conditions famous as tegmen dehiscence and temporal encephalocele (TE). The temporal skeleton are a span of skeleton that form partial of a side of a skull. They perform several pivotal constructional functions, including enclosing a center and center ear and ancillary a temple. In addition, nerves and blood vessels heading to a mind span a bones.

Tegmen dehiscence and TE are singular and underdiagnosed neurotologic conditions where a bone between a mind and a ear is absent. This can be caused by a ongoing ear infection; mishap to a area; or it can be idiopathic mostly compared with patients with aloft physique mass indexes (BMIs) and pang from nap apnea.

Patients pang from these conditions can have a detriment of hearing, drainage of mind liquid out of a ear, dizziness, and a risk of constrictive meningitis. Appropriate government of tegmen dehiscence and TE requires surgical repair. Doctors can perform a normal center fossa craniotomy where partial of a skull is surgically private and a mind is retracted to perspective a problem area. Surgeons afterwards use a microscope to get a proceed perspective to make repairs. This process is invasive and can lead to proxy deficits in cognitive duty and increasing risk of cerebrovascular accidents.

However, Temple physicians recently began charity a reduction invasive and innovative proceed to successfully correct tegmen dehiscence and TE by regulating an endoscopic keyhole craniotomy approach. It is a multidisciplinary bid led by Pamela Roehm, MD, PhD, Professor of Otolaryngology- Head and Neck Surgery in a Temple Head and Neck Institute and a Lewis Katz School of Medicine during Temple University (LKSOM), and Director of Otology and Neurotology during Temple University Hospital (TUH); and Kadir Erkmen, MD, Professor of Neurosurgery during LKSOM, and Director of Cerebrovascular Neurosurgery during TUH. Drs. Erkmen and Roehm recently published their knowledge in a Journal of Neurosurgery.

“We were looking for improved ways to provide patients with these formidable conditions and that meant removing a clearer perspective of a problem area with an endoscope,” says Dr. Roehm. “We started gradually adding a apparatus into a medicine and it worked. We consider this is a distant higher proceed to a normal craniotomy when it comes to treating patients with tegmen dehiscence and temporal encephalocele.”

The use of a endoscope allows for a smaller skin incision, a tiny craniotomy and reduction nullification on a temporal lobe than a normal center fossa craniotomy approach, that means reduction risk of mind nullification injury. Unlike a microscope used in a customary craniotomy, that has a 0 grade view, a endoscope can see around corners during zero, 30 and 70 grade angles in further to a proceed view. Also, due to a tiny distance of a incision, minimal hair shred is required.

“The endoscopic-assisted keyhole craniotomy is a novel proceed in treating temporal bone defects and we have achieved a series of successful surgeries already,” explains Dr. Erkmen. “This is a loyal instance of one of a large ways Temple doctors from opposite departments are teaming adult to be means to offer patients some-more options for their treatment.”
