1/3. Complete ossification of the human falx cerebri.During the routine dissection of the head and neck of an adult male cadaver complete ossification of the falx cerebri was noted. Anomalous ossification was not found in any other dural component or other parts of the body. The brain appeared grossly normal. Histological sections showed normal ossification processes involving the falx cerebri. In addition, rare scattered deposits of metastatic poorly differentiated carcinoma within the trabecular spaces were seen. Reports of isolated islands of ossification involving primarily the most anterior part of the falx cerebri in man are found in the literature. Our case report represents to our knowledge, the first report of complete ossification of this dural partition. Whether this is simply an anomalous configuration or due to the few metastatic cells found within this region remains unclear.- - - - - - - - - - ranking = 1keywords = island (Clic here for more details about this article) |
2/3. The nasolabial musculocutaneous flap: clinical and anatomical correlations.The location of the facial artery beneath the facial mimetic muscles of the nasolabial groove allows surgical development of a true musculocutaneous flap. This report of 20 surgical flaps and six cadaveric dissections highlights the nasolabial musculocutaneous flap with its direct muscle perforating arteries which nourish the overlying skin. The absence of any flap's ischemic failure emphasizes the durability of the flap for various midface and oral reconstructive situations. Inferiorly-based flaps are preferable on the basis of discussed anatomical findings. The musculocutaneous flap is especially suited for circumferential interruption of cutaneous blood supply as in the "V-to-Y" and island pedicle flaps.- - - - - - - - - - ranking = 1keywords = island (Clic here for more details about this article) |
3/3. Combined fasciocutaneous abductor hallucis-medialis pedis transposition flap for defect coverage of the medial ankle.A new method to cover a deep defect of the medial ankle with exposed bone, tendon, or metal implant is presented. In two cases a combined medialis pedis and abductor hallucis muscle flap, each based on separate vessels but linked by the musculocutaneous perforators, was used successfully as an island transposition flap. Among other available options, this flap is, in our opinion, an ideal solution that has superior advantages.- - - - - - - - - - ranking = 1keywords = island (Clic here for more details about this article) |
