Corrective rhinoplasty: medical and legal aspects.

Preoperative planning of any surgical procedure, especially rhinoplasty, is crucial in order to achieve an optimal outcome which will satisfy both the surgeon and patient. Use of imaging and the possibility of virtually displaying the changes planned by the surgeon definitely lead to a better understanding between doctor and patient. Although these new technologies have led to undeniable advantages, they have also generated unprecedented medical and legal problems. The Authors discuss a number of reflections on the legal consequences of image digital processing, the problems related to the storage of such images, and the appropriate way to draft an informed consent.

Pregnancy and tram-flap breast reconstruction after mastectomy: a case report.

A 38-year-old patient had a right radical (Patey) mastectomy for an infiltrating ductal carcinoma followed by chemotherapy and, one year later, a TRAM flap breast reconstruction. She was given clear and exhaustive information about the possible consequences of pregnancy, but despite this she became pregnant four months after the reconstruction. The pregnancy was taken to term despite the appearance at four months of a slow-growing abdominal hernia. In the light of our experience and that of others, we recommend an interval of at least 12 months between breast reconstruction with a TRAM flap and pregnancy.

Spiradenocarcinoma: morphological and immunohistochemical features.

Malignant transformation of spiradenoma is a very rare event and its biologic features have not been fully described. Clinically, these tumours are characterized by the rapid enlargement of a long-standing cutaneous nodule. Microscopic examination discloses the presence of the two components, benign and malignant, whose morphological distinction is not always easy. We report the occurrence of a spiradenocarcinoma within a pre-existing spiradenoma of the cheek in a 48 year old man and review the previously reported cases especially on the basis of their morphological and immunohistochemical characteristics.

[Anesthesiologic problems in patients with Launois-Bensaude-Madelung disease. Clinical case].

Authors report a Launoise-Bensaude-Madelung disease case, in a 64 year old man, admitted to a Plastic Surgical Department for obesity, dysphonia, dysphagia, dyspnea. Early symptoms appeared 20 years before Hospital admission. Lipomatous tissue occupied nape, mandible, neck and shoulders. Surgical exeresis of lipomatous tissue under general anesthesia needed for the patient. Neck movements and mouth opening were short (Mallampati Score = 4); a neck computed tomography showed a tracheal compression and right displacement. Tracheal intubation was considered difficult or impossible. Nose-tracheal intubation was performed using a pediatric fiberoptic instrument as guide for a small gauge tracheal tube. Tracheal stenosis required many attempts for correct nose-tracheal intubation. Fiberoptic instrument as guide for tracheal tube can be useful for patients with Launoise-Bensaude-Madelung disease, when tracheal intubation is considered difficult or impossible. Knowledge of fiberoptic tracheal intubation techniques is mandatory for anesthesiologists, allowing tracheal intubation in patients with anatomical variations of mouth or upper respiratory airways.

[Scrotal reconstruction by cutaneous expansion].

We report on a patient who underwent scrotal reconstruction by cutaneous expansion, a new technique utilized to repair the male genital area. The tissue obtained with this technique permits creating a scrotal pouch and completely free movement of the testes. Unlike the other methods, sufficient skin can be obtained with the exparsion technique. The morphological result achieved with this technique is clearly superior. The absence of scars is underscored.

Long-term histopathologic evaluation of human expanded skin.

Forty-two patients operated on by skin expansion have been contacted after a mean time of 25 months from the last surgery. Two biopsies have been taken from the expanded area of each patient. In 12 patients it has been possible to obtain a similar sampling from the opposite, nonexpanded area of the body. The samples underwent optic microscopy and cell kinetic and DNA content investigations. The epidermal structure of the followed-up skin, compared with the skin of the opposite side of the body, looks normal. The mitotic activity of the epidermal cells has returned to the values of preexpanded skin. The dermis shows a low degree of elastosis and zonal fragmentation of elastic fibers. The hypodermis, where the expander capsule was removed during the last surgery, does not show an accentuated fibrosis.

Skin expansion in head and neck reconstructive surgery.

We used a tissue-expansion technique to achieve soft-tissue reconstruction in congenital and acquired defects of head and neck. One hundred and fifty-five head and neck reconstructions have been performed, with a 6 percent rate of major complications. We present our planning and surgical approach for single areas. From a technical point of view, the only major difference from the rest of literature is the approach to the problem of periprosthetic capsule. In fact, we believe that complete removal of the capsule, which can be achieved without vascular risk thanks to a special technique, is necessary to obtain the best results.

Cell kinetics and DNA content (ploidy) of human skin under expansion.

One question which still remains unanswered concerning expansion of human skin is whether expansion simply stretches the skin or whether it induces a real neo-production of epithelium. To evaluate the proliferative activity of the human skin before and after expansion, we performed an autoradiographic study and a densitometric analysis on sections of skin biopsy from 11 patients. The results of the cellular kinetic study showed that expansion induces an increase in the epidermal proliferative activity. On the contrary, the densitometric analysis did not show a parallel increase of the proliferating cells after expansion. This discrepancy is discussed in terms of the modified morphology of the tissue. The proliferative activity of skin in the back region increases more than in that of the neck. Preliminary results have shown that the proliferative activity increases with time of expansion in days. The presence of a low percentage of cells with altered DNA content indicates, at least over the short term, the absence of dysplastic processes in expanded skins.

The temporalis osteomuscular flap versus the free calvarial bone graft. An experimental study in the growing rabbit.

The authors have conducted an experimental study on the evolution of temporalis osteomuscular flaps compared with calvarial free bone grafts in young rabbits. The evaluation of the results has been performed with macroscopic, radiological and histological investigations in an early and late postoperative phase. This study has confirmed that the bone flaps remain viable and are characterized by a normal evolution. There is no evidence of anomaly of craniofacial growth nor asymmetry when compared with the contralateral side. On the other hand, the free bone grafts show the typical signs of necrosis and resorption. Some asymmetries are produced in comparison with the contralateral side, these being particularly evident in the two-months samples, while the overall craniofacial growth is not seriously impaired. This experimental study confirms the reliability of the temporalis osteomuscular flap in facial reconstruction.

[Splenic cavernous hemangioma. Presentation of a clinical case].

Cavernous haemangioma of the spleen is extremely rare both as a spleen condition and as a vascular malformation. The observation of a seven year old boy with this unusual pathology led to a review of the literature on the subject. Brief remarks on symptoms, diagnosis and therapy are also presented.
