Abstract

OBJECTIVE

Sinus osteotomy is currently performed in equine surgery with conventional surgical methods, such as trephines and oscillating bone saw, leading to subsequent trauma to the bone during cutting. Piezoelectric devices are now used in maxillofacial surgery in humans as a standard tool as it is less traumatic than the oscillating bone saw and shortens the healing period. The aim of this study was to show that the piezoelectric device can be used for equine sinus surgery, compare its use with the oscillating bone saw, and describe the outcome of cases involving osteotomy performed with a piezoelectric surgical device.

ANIMALS

10 horse specimens for cadaveric study and 11 client-owned equines for clinical evaluation.

METHODS

Each cadaveric head underwent a frontonasal bone flap on a randomly assigned side with the piezotome and the oscillating bone saw on the opposite side. Surgical time was recorded for every procedure, and gross examination was performed. A Welch t test was used to compare the surgical time between piezoelectric and oscillating saw use. For the clinical study, animals presented for sinonasal surgery at the hospital from March through October 2023 were included.

RESULTS

Osteotomy was possible with the piezotome in all animals. Surgical time was significantly increased when using the piezotome in comparison with the oscillating saw (P < .05). All clinical patients were treated adequately for the sinonasal disorder they were presented for using the piezotome instead of the oscillating saw. No adverse effects nor long-term complications related to its use have been noted, and preservation of the surrounding soft tissues was evident.

CLINICAL RELEVANCE

The use of a piezoelectric device in equine surgery is feasible. However, the cadaveric study showed an increased surgical time to perform a frontonasal bone flap.
