Anatomical-Surgical study on the Thyro-laryngeal region of Native dogs (Canis lupus familiaris)

The present study was carried out on 10 heads of adult apparently healthy native dogs of both sexes. The samples were attended for the anatomical study on the thyro-laryngeal region. Characteristic features of the latter were declared out, outer landmarks, superficial and deep anatomical structures as well as their relations. The anatomical work in this study tried to set the guidelines for surgeons during the critical interferencein regards to scanty literature. Thyro-laryngeal surgery is indicated for malignant and benign ne-oplasms or hyperplasia of the organs of this region. The ventral midline cervical approach is the most common approach. Caution should be taken to avoid the surrounding neurovascular structures and esophagus. Evaluation of thyroid gland, mandibular salivary glands, and related anatomical structures should be considered before pro-ceeding with surgery. Complications of thyro-laryngeal surgeries include in-traoperative hemorrhage and post-op-erative clinical signs associated with damage to the recurrent laryngeal nerve, parathyroid blood or parathyroidectomy.
