OPERATIVE TECHNIQUE 7.2
VetBooks.ir Thyroarytenoid lateralization

PATIENT POSITIONING
The patient is positioned in dorsal recumbency; the entire neck should be aseptically prepared for surgery. A lateral
approach or a ventral paramedian approach can be used, depending on the surgeon’s preference. The ventral
paramedian approach allows for concurrent tracheotomy, if indicated, without repositioning the patient, and will be
reviewed here.

ASSISTANT
Optional.

SURGICAL TECHNIQUE
Approach

A paramedian skin incision is made on the left side
from 2 cm caudal to the larynx, extending to the
caudal angle of the mandible.

Surgical manipulations
1 The subcutaneous tissues and platysma are incised and blunt dissection is performed lateral to the sternohyoid
and sternocephalic muscles until the dorsal edge of the thyroid can be palpated and lifted (pulled ventrally).

2 An incision is made in the thyropharyngeal muscle along the dorsolateral edge of the thyroid to expose the
thyroid. Stay sutures are then placed, to retract and rotate the larynx laterally, after which the thyropharyngeal
muscle is opened as far as needed.
