Transcutaneous Bone–Anchored Hearing Aids

November 12, 2019 Medical Technology Directory

Health Problem: In the United States, it is estimated that 48 million adults have some type of hearing loss. Hearing loss can be broadly classified as sensorineural (inner ear), conductive (external and middle ear), or mixed. Technology Description: Transcutaneous bone–anchored hearing aids (tBAHAs) transmit sound vibrations from the environment to the inner ear by direct bone conduction through the skull. Unlike percutaneous BAHA (pBAHA) systems that employ a skin-penetrating implant, tBAHA systems use a magnetic connection to join the sound processor and the implant, leaving the skin intact. tBAHAs are intended to improve hearing acuity in individuals who have sensorineural deafness and unilateral...

Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Carcinomatosis Resulting from Peritoneal Mesothelioma

November 5, 2019 Medical Technology Directory

Health Problem: Peritoneal mesothelioma (PM) is a rare primary tumor affecting the serosal (watery) lining of the peritoneum. Technology Description: Hyperthermic intraperitoneal chemotherapy (HIPC) is used as an adjunct to surgery for the treatment of peritoneal carcinomatosis (PC) due to PM. HIPC occurs immediately following optimal cytoreductive surgery (CRS). During HIPC, chemotherapeutic drugs are introduced directly into the peritoneal space to eliminate microscopic tumors on the peritoneal lining and outer surfaces of affected organs and to kill tumor cells that have disseminated throughout the cavity. Heating enhances the cytotoxic effect of the drugs. Controversy: CRS plus HIPC is associated with substantial perioperative morbidity. Definitive patient...

Proton Beam Therapy for Treatment of Head and Neck Cancer

October 30, 2019 Medical Technology Directory

Health Problem: Head and neck cancer (HNC) accounts for approximately 4% of all cancers in the United States, with an estimated 65,410 new HNC diagnoses during 2019 and an estimated 14,620 deaths from the disease. HNC can have a negative impact on a person's quality of life by affecting basic functions such as swallowing, hearing, and speaking.  Technology Description: A form of external beam radiation treatment (EBRT), proton beam therapy (PBT) uses a sophisticated 3-dimensional stereotaxic planning and delivery system to precisely target protons (positively charged, heavy subatomic particles) to bombard a specific tumor mass. Whereas proton and photon techniques should have similar...

Microsurgery for Primary Prevention of Lymphedema Following Surgery for Breast Cancer

October 15, 2019 Medical Technology Directory

Health Problem: Lymphedema refers to the swelling that occurs due to the accumulation of protein-rich fluids in tissue experiencing inadequate lymphatic drainage. One of the most common causes of secondary lymphedema are treatments for breast cancer, including axillary lymph node dissection, mastectomy, lumpectomy, and axillary radiation therapy. Lymphedema is associated with significant morbidity, including loss of limb function, discomfort, and disfigurement. As breast cancer treatments advance and survival rates posttreatment increase, prevention of the sequelae of treatment, including lymphedema, are receiving more consideration.  Technology Description: The lymphatic microsurgical preventive healing approach (LYMPHA) procedure consists of performing lymphaticovenous anastomosis or lymphaticovenous bypass at the...

Percutaneous Bone-Anchored Hearing Aids

October 11, 2019 Medical Technology Directory

Health Problem: In the United States, it is estimated that 48 million adults have some type of hearing loss. Hearing loss can be broadly classified as sensorineural (inner ear), conductive (external and middle ear), or mixed.  Technology Description: This report evaluates the use of percutaneous bone–anchored hearing aids (BAHA) for single-sided sensorineural deafness (SSD) and conductive or mixed hearing loss. BAHA transmit sound vibrations to the inner ear by direct bone conduction through the skull. A titanium screw implanted into the skull allows removable coupling of the sound processor to the bone. BAHA are intended to improve hearing acuity in individuals who have...
