Vascular Compromise

SummaryEleven canine forelimbs were examined using either gross dissection or a modified Spalteholz technique to investigate the blood supply of the palmar metacarpal sesamoid bones. In addition, the sesamoid bones, from two prepared skeletons, were examined for the presence of vascular foramina. Multiple vascular foramina were observed over the sesamoid surface. The most consistent elements of the arterial supply were proximal vessels supplying the axial and dorsal abaxial sides of the bone. In addition, palmar and distal sources often made contributions to the blood supply. Various minor or occasional sources were noted. This study demonstrates that the palmar metacarpal sesamoid bones of the dog have an abundant but highly variable vascular supply.The blood supply of the canine palmar metacarpal sesamoid bones was examined, using several methods, in order to evaluate the possible involvement of vascular compromise in sesamoid disease. It was found that the sesamoid bones have an abundant blood supply which is presumably resistant to disruption.

AbstractAdvances in free flap reconstruction of complex head and neck defects have allowed for improved outcomes in the management of head and neck cancer. Technical refinements have decreased flap loss rate to less than 4%. However, the potential for flap failure exists at multiple levels, ranging from flap harvest and inset to pedicle lay and postoperative patient and positioning factors. While conventional methods of free flap monitoring (reliant on physical examination) remain the most frequently used, additional adjunctive methods have been developed. Herein we describe the various modalities of both invasive and noninvasive free flap monitoring available to date. Still, further prospective studies are needed to compare the various invasive and noninvasive technologies and to propel innovations to support the early recognition of vascular compromise with the goal of even greater rates of flap salvage.

Ossifying fibroma (OF) is a rare, benign, fibro-osseous lesion of the jawbone characterised by replacement of the normal bone with fibrous tissue. The fibrous tissue shows varying amount of calcified structures resembling bone and/or cementum. The central variant of OF is rare, and shows predilection for mandible among the jawbone. Although it is classified as fibro-osseous lesion, it clinically behaves as a benign tumour and can grow to large size, causing bony swelling and facial asymmetry. This paper reports a case of large central OF of mandible in a 40-year-old male patient. The lesion was treated by segmental resection of mandible. Reconstruction of the surgical defect was done using avascular fibula bone graft. Role of three-dimensional printing of jaw and its benefits in surgical planning and reconstruction are also highlighted.
