AbstractAlloplastic facial transplantation has become a new rung on the proverbial reconstructive ladder for severe facial wounds in the past couple of decades. Since the first transfer including bony components in 2006, numerous facial allotransplantations across many countries have been successfully performed, many incorporating multiple bony elements of the face. There are many unique considerations to facial transplantation of bone, however, beyond the considerations of simple soft tissue transfer. Herein, we review the current literature and considerations specific to bony facial transplantation focusing on the pertinent surgical anatomy, preoperative planning needs, intraoperative harvest and inset considerations, and postoperative protocols.

Mastoid Region

Cholesteatoma is a non-neoplastic, keratinized squamous epithelial lesion that affects the temporal bone. The middle ear is the most frequent, while the isolated cholesteatoma of the mastoid is rare. The aim of this study was to describe a rare case of isolated mastoid cholesteatoma with no involvement of aditus ad antrum and middle ear including a literature review of the topic. This case report describes the case of a 58 years old female with a cholesteatoma isolated in the mastoid region, evidenced by imaging (computer tomography and magnetic resonance). A mastoidectomy was performed: mastoid process was completely involved, but antrum was not reached. Moreover, it reached the soft tissue of stylomastoid foramen as well as the posterior belly of the digastric muscle. In the literature few articles described cases of cholesteatoma isolated in the mastoid region. Research was conducted using PubMed and reference list and there were considered only reports about cholesteatoma exclusively located in the mastoid process without involvement of antrum or middle ear. Fourteen articles were included in this review, with a total number of 23 cases of cholesteatoma isolated in the mastoid region. All papers analyzed reported the cases of isolated mastoid cholesteatoma that presented a congenital origin. Its diagnosis is difficult, therefore, imaging evaluation is mandatory and surgery is the treatment of choice. Mastoid cholesteatomas without involvement of aditus ad antrum and middle ear are rare and only 23 cases are reported in literature. Our case is in line with all clinical and diagnostic features of this rare disease, but it is the only one that evidenced an exposure of the soft tissue of stylomastoid foramen as well as the posterior belly of the digastric muscle. The treatment of choice was the surgical one, avoiding damaging of important anatomo-functional structure.

The anterolateral thigh free flap is described in terms of its surgical anatomy, techniques of elevation and its application in seven cases of trauma to the hand. The particular advantages of this free flap for reconstructing a variety of hand defects are demonstrated. Flap refinements that have potential applications for hand surgery are described.

Mastoid Region

We report our experience with titanium implants for extra-aural rehabilitation in the mastoid region with a bone-anchored hearing aid (BAHA) and auricular prosthesis. The purpose of this study was to evaluate the clnical status of the soft tissue adjacent to 63 skin-penetrating devices in 43 patients and to compare our findings with those of other reports. Forty-four fixtures have been implanted in 36 patients for the BAHA and 19 in seven patients for the auricular prostheses. The evaluation concerns osseointegration, pain in the mastoid area, skin reaction around the abutment and removal of the abutment. Three implants extruded; one due to trauma and two with no explanation. Follow-up ranged from 3 to 60 months after surgical implantation. The first outpatient check-up was performed at three months after implantation and then every six months. The soft tissue reaction around the percutaneous unit was classified at each control according to the classification proposed by Holgers et al.1 There was no irritation (type 0) in 87.5% of the controls for the BAHA group and in 87.2% for the group of auricular prostheses. No adverse skin reactions were noted in 61.36% of the BAHA group and in 66.66% of the auricular prosthesis group. Results of this study confirm the skin's ability to tolerate a skin-penetrating unit made of pure titanium. The importance of reducing the thickness of the skin around the implant and of local hygienic conditions is emphasized.

Gallium 67

The radionuclide gallium-67 (67Ga) localizes preferentially but not specifically in many human and experimental soft-tissue tumors. Because of this localization, 67Ga is used in clinical trials to detect humar. cancers by external scintiscanning methods. However, the fact that 67Ga does not localize specifically in tumors requires for its eventual clinical usefulness a fuller understanding of the mechanisms that control its deposition in both malignant and normal cells. We have previously reported that 67Ga localizes in lysosomal-like bodies, notably, although not exclusively, in macrophages of the spocytaneous AKR thymoma. Further studies on the uptake of 67Ga by macrophages are needed to determine whether there are factors related to malignancy that might alter the localization of 67Ga in these cells and thus provide clues to discovering the mechanism of 67Ga localization in tumor tissue.

A new virus, established as a member of the herpesvirus group by electron microscopy, was isolated from spontaneously degenerating cell cultures derived from the kidneys and lungs of two normal tree shrews. The virus was found to replicate best in cells derived from the homologous species. The cells used were a tree shrew cell line, T-23, which was derived from a spontaneous soft tissue sarcoma. The virus did not multiply or did so poorly for a limited number of passages in human, monkey, rodent, rabbit or chick embryo cells. In the T-23 cells, the virus behaved as members of the subgroup B of herpesvirus, in that the virus remained primarily cell associated.
