Facial vein is the main vein of the face. Though its origin is constant, it frequently shows variations in its termination. We report a rare type of variation of facial vein. The right facial vein coursed transversely across the masseter, superficial to the parotid duct and entered into the substance of the parotid gland, at its anterior border. Deep dissection of the gland revealed the abnormal termination of facial vein into the superficial temporal vein. The transverse facial vein drained into the facial vein. The superficial temporal vein after receiving the facial vein continued as retromandibular vein. Knowledge of this anomalous course and termination of facial vein may be important for the surgeons doing parotid, maxillofacial and plastic surgeries.

The extensor digitorum brevis muscle (EDB) is a practical option for use as an island flap or free flap when reconstructing soft tissue defects in the ankle as well as in the entire lower limb. It is frequently used to correct crossover toe deformity and other painful toe disorders. We evaluated the morphometry of the EDB in 44 formalin-fixed limbs. Length and width of the muscles were measured. Surface area was calculated as the product of length and width of the muscle. The length of each tendon was also measured from its origin to the point of distal attachment. Presence of any additional tendons was noted. Mean length, width, and surface area of the muscle were 7.39+/-0.71 cm, 4.1+/-0.37 cm, and 30.5+/-4.78 cm2 on the right side and 7.2+/-0.84 cm, 3.9+/-0.37 cm, and 28.4+/-5.35 cm2 on the left side, respectively. Morphometry of the tendons revealed that the tendon of the great toe had the highest mean length (9.5 cm) and the tendon of the fourth toe had the lowest mean length (6.3 cm). Four of the limbs studied (9.09%) had only three tendons. Three of the limbs studied (6.81%) had five tendons, and in one exceptional case (2.27%), six tendons were detected. These observations have significant value and are applicable to plastic and orthopedic surgery.

Veins of the head and neck exhibiting anatomical variations or malformations are clinically significant. Anatomical variation in the external jugular vein is very common. However, anatomical variation in the retromandibular vein is rare. In this paper, we report a rare case of complete absence of the retromandibular vein. In the absence of the retromandibular vein, the maxillary vein divided into anterior and posterior divisions. The posterior division joined the superficial temporal vein to form an atypical external jugular vein, and the anterior division joined the facial vein to form an anonymous vein. In clinical practice, radiologists and surgeons use the retromandibular vein as a guide to expose the branches of the facial nerve during superficial parotidectomy. Therefore, absence of the retromandibular vein is a hurdle during this procedure and may affect the venous drainage pattern from the head and neck.
