Human left atrial appendage anatomy and overview of its clinical significance.

Objective: The left atrial appendage (LAA) is an important anatomic region since it is a source of thromboembolism in patients with atrial fibrillation. Although this anatomic and clinical relation it has received little attention until recent years.

Methods: This descriptive laboratory study was performed in 56 hearts of adult formalin fixed cadavers.

Anatomical features of the opening of the nasolacrimal duct and the lacrimal fold (Hasner's valve) for intranasal surgery: a cadaveric study.

The location and size of the opening of the nasolacrimal duct and the lacrimal fold (Hasner's valve) are variable. These features have clinical importance in nasal surgery because of the difficulty in determining their location. The aim of this study was to demonstrate the anatomical features of the opening of the nasolacrimal duct and the lacrimal fold and to discuss the importance of such knowledge in minimizing the risk of injury at surgery.

The incidence and anatomical features of the McKenzie branch: a cadaver study.

Aim: The aim of this study was to demonstrate the morphological characteristics of the connections between the spinal accessory nerve and the anterior root of the first cervical nerve (C1) which is also called the McKenzie branch.

Material And Methods: The cranial cervical regions of 49 specimens from 27 human cadavers were used for this study under an operating microscope. The topographical relationship of the accessory nerve to the anterior roots of C1 were studied.

The clinical importance of the relationship between the deep peroneal nerve and the dorsalis pedis artery on the dorsum of the foot.

Background: The aim of this study was to describe the relationship between the deep peroneal nerve and the dorsalis pedis artery to help ensure a safer surgical approach in flap surgery.

Methods: The dissection of 36 cadaver lower limbs was undertaken to describe the relationship of the deep peroneal nerve to the dorsalis pedis artery in the anterior tarsal tunnel and on the dorsum of the foot.

Results: Four distinct relationships of the deep peroneal nerve to the dorsalis pedis artery were determined.

The Distribution of the Superficial Peroneal Nerve on the Dorsum of the Foot and its Clinical Importance in Flap Surgery.

Background: The superficial peroneal nerve (SPN) and its branches are at risk during surgical exposures. Our study aimed to demonstrate the distribution of the SPN on the dorsum of the foot to aid in surgical procedures close to this nerve.

Methods: The SPN was dissected in 30 cadaver lower limbs (13 male and two female).
