Inner-ear Volume Study Leads To Higher Surgery Success Rates
Main Category: Ear, Nose and Throat News
Article Date: 03 Mar 2007 - 0:00 PST

Children suffering from holes in their eardrums could have better success rates following surgery, thanks to findings from doctors at West Virginia University.

The study was published in the February, 2007 issue of Otolaryngology Head and Neck Surgery, the official journal of the American Academy of Otolaryngology-Head and Neck Surgery Foundation. Conducted by doctors in the Department of Otolaryngology, the study measured success rates of patching eardrum holes based on volume or space measurements in the ear.

Holes result from either injury or prior ear problems, such as ear tubes. Perforated eardrums can predispose the ear to infection or result in hearing loss.

"Until this study, there were no clear guidelines as to when kids should have surgery to patch the holes," Hassan Ramadan, M.D., principal investigator on the study, said. Dr. Ramadan is the vice-chair of the Department of Otolaryngology at WVU and director of the Sinus Center.

He and his co-investigators, Daniel Merenda, M.D.; Kazunari Koike, M.D. and Majid Shafiei have published findings that use a common test involving an audiologist's probe tool, called a tympanometry, to measure the volume of ear space.

The doctors found that having higher tympanogram volumes could result in a nearly 90 percent success rate for patching the perforation.

The typmanometry probe is commonly used by ear specialists and consists of a loudspeaker emitting a low frequency tone, a microphone measuring sound pressure levels in the ear canal and a manometer, that also measures pressure.

Patients whose volume does not meet doctors' measurement specifications should wait to have an ear operation. Dr. Ramadan warns that patching too early can either lead to a fluid build up or not fully close the hole.

"Prior to this research, doctors typically looked at age and the child's history of infections to decide when to patch," Dr. Ramadan said. "Our research proves that testing inner ear volumes allows specialists to be more scientific and accurate in their decisions of whether to operate."

1. Inner-ear ：the essential part of the vertebrate organ of hearing and equilibrium that typically is located in the temporal bone, is innervated by the auditory nerve, and includes the vestibule, the semicircular canals, and the cochlea -- called also internal ear.
2. eardrum：tympanic membrane，a thin membrane separating the middle ear from the inner part of the external auditory canal that vibrates in response to sound energy and transmits the resulting mechanical vibrations to the structures of the middle ear -- called also eardrum, tympanum.
3. Hassan Ramadan：Dr. Ramadan is a board certified otolaryngologist who has subspecialty expertise in pediatric otolaryngology, which includes ear, nose, and throat diseases in children as well as expertise in nasal and sinus diseases. He has extensive experience in endoscopic sinus surgery and is the director of the WVU Sinus Center. He holds memberships in several regional, national and international medical societies and has presented talks at many national and international meetings. He has over fifty publications in referred medical journals.
Dr. Ramadan attended medical school at the American University of Beirut. He traveled to the United States in 1986 where he completed postgraduate training at Harvard Medical School in Boston and Lenox Hill Hospital in New York City. In the summer of 1990, Dr. Ramadan joined the Department of Otolaryngology at West Virginia University. He is currently Professor and Vice Chairman in the Department of Otolaryngology and has a joint appointment as Professor in the Department of Pediatrics. He is a fellow of the American Academy of Otolaryngology/Head & Neck Surgery, the American Rhinologic Society, and the American College of Surgeons.

Children suffering from holes in their eardrums could have better success rates following surgery, thanks to findings from doctors at West Virginia University.
患有鼓膜穿孔的儿童在下述外科手术中获得更高的成功率，这全得益于西部弗吉尼亚大学医师的研究发现。
The study was published in the February, 2007 issue of Otolaryngology Head and Neck Surgery, the official journal of the American Academy of Otolaryngology-Head and Neck Surgery Foundation.
这项研究结果发表在美国耳鼻咽喉头颈外科基金学会的官方杂志――《耳鼻咽喉头颈外科杂志》2007年2月刊上。
Conducted by doctors in the Department of Otolaryngology, the study measured success rates of patching eardrum holes based on volume or space measurements in the ear.
这项研究是由耳鼻咽喉科医师领导的。该研究测量以内耳容积或空间测量结果为基础的耳膜穿孔修补的成功率。
Holes result from either injury or prior ear problems, such as ear tubes.
外伤或耳部先前的疾病（比如耳道）结果导致耳膜穿孔。
Perforated eardrums can predispose the ear to infection or result in hearing loss.
耳膜穿孔使耳部易于感染或导致听力丧失。
"Until this study, there were no clear guidelines as to when kids should have surgery to patch the holes," Hassan Ramadan, M.D., principal investigator on the study, said.
Hassan Ramadan医学博士是这项研究的主要研究人员。他说：“直到进行这项研究时，什么时候该给孩子进行外科手术来修补耳膜穿孔才有了明确的指导方针。”
Dr. Ramadan is the vice-chair of the Department of Otolaryngology at WVU and director of the Sinus Center.

他和他的合作研究者Daniel Merenda医学博士、Kazunari Koike医学博士以及Majid Shafiei已经发表了他们的研究发现。他们用鼓室压测量法（一种听力学家探针工具）等普通测试来测量耳部空间容积。
The doctors found that having higher tympanogram volumes could result in a nearly 90 percent success rate for patching the perforation.
医师们发现鼓室导抗图容积较高的患儿的耳膜穿孔修补成功率近90％。
The typmanometry probe is commonly used by ear specialists and consists of a loudspeaker emitting a low frequency tone, a microphone measuring sound pressure levels in the ear canal and a manometer, that also measures pressure.
耳科专家经常使用这种鼓室测量方法。声导抗测量仪由一个发射低频音的扬声器、一个测量内耳道声压级的麦克风和一个也用来测量压力的测压计组成。
Patients whose volume does not meet doctors' measurement specifications should wait to have an ear operation.
患者的内耳容积不符合医师的测量规范则其耳部手术将延期。
Dr. Ramadan warns that patching too early can either lead to a fluid build up or not fully close the hole.

"Prior to this research, doctors typically looked at age and the child's history of infections to decide when to patch," Dr. Ramadan said.
