Safety and Effectiveness of Total Thyroidectomy and Its Comparison with Subtotal Thyroidectomy and Other Thyroid Surgeries: A Systematic Review.

Diseases associated with the thyroid gland are one of the most frequently seen endocrine disorders across the globe. Total thyroidectomy is currently the preferred treatment for many thyroid diseases. Controversies exist among surgeons regarding safety of total thyroidectomy due to the risk associated with it like postoperative hypoparathyroidism or recurrent laryngeal nerve damage.

Anatomical Study of the Ulnar Nerve Variations at High Humeral Level and Their Possible Clinical and Diagnostic Implications.

Background. Descriptive evaluation of nerve variations plays a pivotal role in the usefulness of clinical or surgical practice, as an anatomical variation often sets a risk of nerve palsy syndrome. Ulnar nerve (UN) is one amongst the major nerves involved in neuropathy.

Atypical arterial supply to the spleen by polar branches of splenic artery and accessory splenic artery - a case report.

Vascular anomalies of the spleen are usually asymptomatic. However, variant anatomy of splenic artery becomes clinically important, when the patients undergo diagnostic angiography for gastrointestinal bleeding or during transcatheter therapy. We report here a concurrent variant arterial pattern of the spleen.

Eight prehilar branches of the right renal artery.

Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vessels at the hilum of the kidney. During routine dissections, a variation in the branching pattern of the right renal artery was noted in an adult male cadaver.

Absence of retromandibular vein associated with atypical formation of external jugular vein in the parotid region.

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.

An Anatomical Variation of the Lesser Occipital Nerve in the "Carefree part" of the Posterior Triangle.

The occurrence of the lesser occipital nerve (LON) at an anomalous location in the "carefree part" within the posterior triangle has been seldom reported in the literature. We are reporting a rare case of location of the LON in the "carefree part" of the posterior triangle, in a 55-year-old formalin embalmed male cadaver. LON, after emerging from the posterior margin of the sternomastoid muscle (SM), ran obliquely towards the trapezius muscle.

Presence of multiple tendinous insertions of palmaris longus: a unique variation of a retrogressive muscle.

Background: Palmaris longus, being the most variable muscle of the upper extremity is generally considered important morphologically rather than functionally. The palmar aponeurosis represents the distal part of the tendon of Palmaris longus.

Case Details: We report here a unique case of palmaris longus presenting variation distally as its tendon divides to gain multiple attachments with the fascia covering the abductor pollicis brevis, flexor retinaculum and the tendon of flexor carpi ulnaris.

A rare variation in the origin and course of the artery of penis.

Vascular variations of the penis are very rare. Awareness of its variations is of utmost importance to the urologists and radiologist dealing with the reconstruction or transplants of penis, erectile dysfunctions, and priapism. We report an extremely rare variation of the artery of the penis and discuss its clinical importance.

Presence of Arteriovenous Communication between Left Testicular Vessels and Its Clinical Significance.

Maintenance of testicular temperature below body temperature is essential for the process of spermatogenesis. This process of thermoregulation is mainly achieved by testicular veins through pampiniform venous plexus of the testis by absorbing the heat conveyed by the testicular arteries. However, this mechanism of thermoregulation may be hampered if an abnormal communication exists between the testicular vessels.

Unique formation of sciatic nerve below the piriformis muscle - a case report.

Dorsal and ventral divisions of ventral rami of lower lumbar and sacral spinal nerve were found to pass ventral and dorsal to the piriformis muscle respectively. These divisions joined each other below the piriformis muscle to form sciatic nerve. This low formation of sciatic nerve was observed in distal part of left gluteal region of a 50-year-old male cadaver.

Variant origin of an arterial trunk from axillary artery continuing as profunda brachii artery--a unique arterial variation in the axilla and its clinical implications.

Background: Axillary artery is known to show different variations mostly in its branching pattern. Similarly, the origin of profunda brachii is often encountered with abnormality. Therefore, when the vascular variations in the upper limb persist, mostly it is confined to its branching pattern followed by its variant origin.

Duplicated right crus of the diaphragm: a cadaveric case report.

The lumbar part of the diaphragm arises from the lumbar vertebrae by right and left crura. The duplication of crura of the diaphragm is rarely reported in the past. During regular dissection classes to the medical students, we came across a case of duplicated right crus of the diaphragm.

The foramen ovale morphometry of sphenoid bone in South Indian population.

Background: The foramen ovale is an oval opening in the greater wing of sphenoid bone transmitting the mandibular nerve as its major content. It serves as an important landmark for neurosurgeons in certain procedures as to gain access to trigeminal nerve. Therefore, its topographic position in relation to adjacent bony landmarks provides useful tool during these procedures.

An anatomical variation in the formation of the inferior root of ansa cervicalis.

During regular dissections, we observed an unusual organization of the inferior root of Ansa Cervicalis (AC). The superior root of ansa arose normally from the hypoglossal nerve. The ventral ramus of the C2 spinal nerve divided into two branches.

A rare anatomical variation of the Berrettini anastomosis and third common palmar digital branch of the median nerve.

Variations in the origin and distribution of Berrettini anastomosis between the digital branches of the ulnar and median nerves exist and are well described in the literature. During regular dissections by medical students, we encountered a rare variation in the left hand of an approximately 50-year-old male cadaver. Berrettini anastomosis connecting the third common palmar digital branch of the median nerve with the fourth common palmar and proper palmar digital branches of the ulnar nerve presented a plexiform nature.

Additional circular intercostal space created by bifurcation of the left 3rd rib and its costal cartilage: a case report.

Introduction: In the thorax there are normally 11 pairs of intercostal spaces: the spaces between adjacent ribs. The intercostal spaces contain intercostal muscles, intercostal nerves and vessels.

Case Presentation: During a routine dissection for undergraduate medical students, we observed a variation involving the left 3rd rib and 3rd costal cartilage in the cadaver of a man of Indian ethnicity aged about 65 years.

Variant course of posterior circumflex humeral artery associated with the abnormal origin of radial collateral artery: could it mimic the quadrangular space syndrome?

Variations in the origin of axillary artery branches are common. But, distinctly abnormal course of its posterior circumflex humeral branch is rare. We are reporting a case of posterior circumflex humeral artery (PCHA) originating from the axillary artery, passing through lower triangular space to reach the scapular region where it accompanied the axillary nerve and posterior circumflex humeral vein to pass around surgical neck of humerus, deep to the fibers of deltoid.
