Accurate Diagnosis, Effective
Treatment
Glomus
tumor is a slow-growing, vascular tumor located at the skull base. Also known
as a glomus jugulare, glomus tumor is the most common tumor of the temporal
bone, which contains the middle and inner portions of the ear.
Specialists
at UT Southwestern are experts at diagnosing and treating glomus tumors, using
the latest in image guidance and microsurgical techniques as well as
rehabilitative services to restore quality of life for each patient.
Symptoms of Glomus Tumors
Patients
often hear their own heartbeat in the affected ear. Other symptoms can include:
- Difficulty swallowing
- Hoarseness
- Hearing loss
- Slurred speech
- Facial weakness
In rare
cases, a patient will experience pain or bleeding from the ear.
Diagnosis
This
tumor is often diagnosed through a simple physical exam. Physicians at UT
Southwestern are experts at distinguishing glomus tumor from glomus tympanicum,
another common tumor affecting the ear that can have an identical appearance to
the glomus jugulare tumor.
Glomus jugulare
tumors grow on the jugular bulb, while glomus tympanicum tumors grow in the
middle ear space. Distinguishing these tumors can typically be done through a
detailed ear microscope exam or with a magnetic resonance
imaging (MRI) or
computed tomography (CT) scan. This
distinction is important because the two types of tumor require different
treatment.
Treatment for Glomus Tumors
Treatment
of a glomus tumor depends on a patient’s age, overall health, symptoms, and the
size of the tumor. Physicians at UT Southwestern collaborate to determine what
approach will work best for each patient.
Treatment
plans can include:
- Observation: Monitoring the
tumor using serial imaging studies is often recommended for patients of
advanced age, those who have multiple health issues, or those who prefer this
option.
- Partial or total
surgical removal: This approach is typically recommended in younger patients. Partial
removal can be used when the lower cranial nerves are intact, while total
removal is usually attempted when the nerves are nonfunctional.
- External beam
radiation: This treatment
is conducted five days a week for several weeks to shrink or destroy the tumor.
- Stereotactic
radiation therapy: This treatment can be completed in one day or over a three-day period and
can shrink or destroy the tumor.
- Combination: Depending on each
patient’s specific needs, a combination of surgery and conventional or
stereotactic radiation therapy might be recommended.
Recovery
depends on the location, size, and invasiveness of the tumor. Specialists at UT
Southwestern work with each patient to address any postoperative issues, such
as:
- Hoarseness: Whether from the
tumor or treatment, hoarseness can be improved through speech therapy, vocal
cord injection therapy, or surgical repositioning of the vocal cord.
- Shoulder pain: Caused by the
effect of the tumor on spinal accessory nerves, shoulder pain often responds
well to physical therapy.
- Hearing loss: In some cases,
hearing loss improves after the tumor is removed. If it doesn’t, several types
of hearing aids can also help.
- Swallowing problems: These issues can
result from the tumor or the treatment, and they can be improved with speech
therapy.
Research and Clinical Trials
Patients
also benefit from the leading research conducted at UT Southwestern, which
often includes clinical trials offered at few other centers in the country and
which helps speed better treatment to patients.
