Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

Medical device safety and performance analysis.
Surgical technology and risk assessment.

Background:

Ultrasonic bone saws are gaining traction, replacing traditional osteotomy tools in craniofacial and rhinoplasty procedures.
Understanding potential adverse events is crucial for enhancing surgical safety.

Purpose of the Study:

To classify and analyze device- and patient-related events linked to ultrasonic bone saw usage.
To identify common malfunctions and patient injuries associated with these devices.

Main Methods:

Analysis of 432 medical device reports from the FDA's MAUDE database (2014-2024) concerning Piezosurgery and Sonopet devices.
Inclusion of search terms: "piezo saw," "piezoelectric," "piezosurgery," and "sonopet."

Main Results:

Most common device issues included inability to irrigate (186 reports), device overheating/melting (148), and insert tip fracture (58).
Patient-related events occurred in 31 cases, leading to 15 morbidities, primarily thermal burns (13) and iatrogenic foreign bodies (8).
Device malfunctions caused 18 significant case delays and 1 abortion, with patient injuries requiring conservative treatment (10 cases) or further surgery (7 cases).

Conclusions:

Device overheating, fracture, thermal burns, and foreign bodies are key risks associated with ultrasonic bone saws.
Awareness of these risks can guide surgeons in improving the safe application of ultrasonic bone saws in craniofacial and rhinoplasty surgeries.
