Foramen arcuale: a rare morphological variation located in atlas vertebrae.

Objective: To investigate the incidence of foramen arcuale in dry atlas vertebrae which may cause clinical problems.

Materials And Methods: Eighty-one dry human cervical vertebrae were examined. The evaluated parameters of two atlas vertebrae including foramen arcuale were as follows: maximum antero-posterior, transverse diameters and areas of the right and left superior articular facets and transverse foramina; maximum antero-posterior diameters, heights, areas and central sagittal thickness of bony arch forming roof of foramen arcuale, respectively.

Morphological and Morphometric Analysis of Foramen Magnum: An Anatomical Aspect.

Objective: To investigate the detailed morphological and morphometric analysis of foramen magnum (FM) in dry cranii.

Methods: One hundred fifty skulls of unidentified sex were macroscopically examined and were photographed with Canon 400B (55 mm objective). According to tooth eruption of the skulls, they were accepted as adults.

Morphometrical aspect on angular branch of facial artery.

Anatomic variability and anastomosis of the angular artery of the facial artery with the other arteries are important for both anatomists and surgeons. In particular, the angular artery is a significant landmark in dacryocystorhinostomy. Because of variations on anatomy of the angular artery, there are limited numbers of anatomic studies on the flaps of facial region.

Anatomy of vastus lateralis muscle flap.

A vastus lateralis muscle flap is used as a pedicled and free flap. In this study, the vastus lateralis muscles of 15 adult formalin-fixed cadavers (30 cases) were dissected. The dominant pedicle was found to be descending branch of the lateral circumflex femoral artery.

Anatomy of gracilis muscle flap.

Gracilis muscle flap is commonly used in reconstructive surgery. The gracilis muscles of 15 formalin-fixed adult cadavers (30 cases) were dissected with 4× loupe magnification. The most proximal pedicle of gracilis muscle was the deep branch of the medial circumflex femoral artery.

Anatomic bases of superficial temporal artery and temporal branch of facial nerve.

The superficial temporal artery (STA)-based flaps have been used for different reconstructive purposes. These operations may cause facial nerve injury. The variations of the STA and its relation to temporal branch of the facial nerve (TBFN) were evaluated in this study.

Supraclavicular artery flap.

Supraclavicular artery-based flaps provide aesthetic and functional coverage for the head and neck region. Fourteen formalin-fixed cadavers were dissected bilaterally, and 28 supraclavicular arteries were evaluated. The origin of the supraclavicular artery was transverse cervical artery in 62.

The premasseteric branch of facial artery: its importance for craniofacial surgery.

Aim: The masseter muscle is often exploited by craniofacial surgeons in transposition operations to correct facial palsy, benign masseteric hypertrophy; or neurectomy-induced atrophy of the muscle. A clear understanding of the course of the premasseteric branch of the facial artery and its relations with adjacent structures is essential in maneuvering the masseter muscle safely. In the present study the premasseteric branch was analyzed in details.

Flap and incision design in implant surgery: clinical and anatomical study.

Objectives: The protection of microcircular support which is essential for healing gains importance if implant surgery is considered to affect the blood flow. The aim of the study is to establish the artery territories supplying the blood into the oral mucosa in the cadavers and to demonstrate the mucosal delivery pattern and to evaluate the effects of different incision types on the healing in the patients having the implant application.

Materials And Methods: The study was planned in two stages as cadaver and clinical investigations.

Anatomic study of the vasculature of the submental artery flap.

The submental artery island flap is a versatile option in head and neck reconstruction. This flap may be used for the coverage of perioral, intraoral, and other facial defects, leaving a relatively acceptable donor-site scar. In this study, the submental region of 13 formalin-fixed cadavers was dissected bilaterally.

Cadaveric study of the arterial anatomy of the upper lip.

Arterial distribution of the upper lip was investigated in this study. The location, course, length, and diameter of the superior labial artery and its alar and septal branches were determined on 14 preserved cadaver heads. Another cadaver head was used to show the arterial tree by the colored silicone injection technique.

Arterial anatomy of the lower lip: a cadaveric study.

The aim of the study was to investigate the arterial anatomy of the lower lip. The location, course, length, and diameter of the inferior labial artery and the sublabial artery were revealed by bilateral meticulous anatomic dissections in 14 adult male preserved cadaver heads. Another cadaver head was used for silicone rubber injection to fill the regional arterial tree.

Bilateral duplication of the optic canals.

During an autopsy survey of 369 human skulls, one with bilateral (0.27%) and one with unilateral (0.27%) duplication of the optic canal were reported.
