In most cases of monostotic or monofocal fibrous dysplasia of the craniofacial region, modern surgical techniques allow an aggressive but definitive treatment with good functional and aesthetic results. The authors perform radical treatment even in cases involving the maxilla and mandible, and prefer a conservative approach only in polyostotic cases and McCune-Albright syndrome.
The aim of our study was to demonstrate the role of certain risk factors in reconstructive head and neck surgery with free flaps. The data taken from the charts of all patients who received free flap for head and neck reconstruction in our department between January 2001 and December 2004 were analyzed. We evaluated the association of preexisting risk factors with the onset of surgical complications such as orocutaneous fistulae, flap infections, hematomas, thrombosis, and necrosis. One hundred and twenty-two free flaps have been used for the reconstruction of head and neck area in 118 patients. Preoperative risk factors included smoking habit (77 patients), alcohol use (6 patients), hypertension (9 patients), diabetes mellitus (8 patients), family history positive for vascular disorders (27 patients), and hypercholesterolemia/hypertriglyceridemia (5 patients). The percentage of full flap survival was 95.08%. Statistical analysis showed that diabetes mellitus (P < 0.01) is significantly associated with a negative prognosis for free flap reconstructive operation, whereas a smoking habit seemed to be at the verge of statistical significance. Therefore, our current practice is to prefer as much as possible the use of local flaps as opposed to free flaps in the reconstruction of head and neck defects in diabetic patients.
No data in the literature report the specific invasion of the orbit from ethmoidal tumors, although such a pattern of involvement of the orbit frequently occurs because of the thin lamina papyracea separating the two structures. From January 1986 to January 2003, 38 patients with untreated primary ethmoidal malignancies were observed at the Unit of Maxillo-Facial Surgery of the University "La Sapienza" in Rome. Personal data were obtained from review of the personal clinical file of each. Orbital invasion was present in 24 patients with ethmoidal malignancy. Three stages of orbital invasion were identified. The average overall survival, with the Kaplan-Meyer method, was 61.4% after 1 year and 51.1% at 5 and 10 years. Intracranial involvement is the main element for short-term negative prognosis. Orbital exenteration is fundamental if grade III orbital invasion occurs because it ensures an improvement of the disease-free survival.
Traumas, malformative or dysplastic pathologies, atrophy, osteoradionecrosis, and benign or malignant neoplasm can cause bone deficits in the mandible. Consequent mandibular defects can determine aesthetic and functional problems; therefore, being able to perform a good reconstruction is of critical importance.Several techniques have been proposed for mandibular reconstruction over the years. In this article, we present and discuss the evolution during the time of the methods of mandible reconstruction as well as pros and cons of each procedure on the basis of experience of 10 years in the maxillofacial department of the Catholic University of Sacred Heart of Rome.Free flaps represent the gold standard method of reconstruction of large mandibular defects: the fibula bone flap represents the best choice for large defects involving the arch and the mandibular ramus, whereas the deep circumflex iliac artery represents a valid alternative for mandibular defects involving the posterior region.In cases where free flap reconstructions are contraindicated, the use of regional pedicle flap combined with autologous bone grafts still represents a valid choice. Patients who are not deemed suitable for long and demanding surgery can still be treated using alloplastic materials in association with regional pedicle flap or, when adjuvant radiation therapy is needed, by simple locoregional pedicle flap. Finally, in selected cases, the bone transporting technique should be considered as a valid alternative to the more "traditional" reconstructive methods because of the extraordinary potential and its favorable cost-benefit ratio.
This paper presents our clinical experience with head and neck reconstruction using radial forearm flap and our preliminary experience with anterolateral thigh (ALT) flap. We analyze the advantages and disadvantages of these 2 flaps from the complications we have encountered. From 1993 to 2006, the radial forearm flap has been used in 75 patients, whereas we began using the ALT flap in 2006. Since this time, we have used the ALT flap in 10 patients. One flap partial loss was observed in a patient who underwent reconstruction of the ethmoid region and nasal bones with an osteofasciocutaneous radial flap. In one patient who underwent reconstruction with ALT flap, inadequate venous outflow was discovered, and the flap was salvaged with reexploration, removing of the cutaneous component of the flap and using antithrombotic agents. Donor-site complications were experienced in 8 of 75 patients who underwent reconstruction with radial forearm flap, whereas all donor thighs healed uneventfully. Anterolateral thigh flap gives optimal results either at the donor site or at the accepting site, being easy to harvest and providing an ideal reconstructive option. Nevertheless, radial forearm flap remains a valuable alternative in case of a thin soft tissue reconstruction because of its thinness and versatility; furthermore, it can provide a long and constant pedicle of large caliber. However, since we began using the ALT flap, we had only performed this flap with respect to radial forearm flap because of its lower donor-site morbidity.
Different reconstruction techniques of the anterior and middle skull base as consequence of a defect after surgical treatment of neoplastic pathologies are described in the literature. The aim of the present study is to present our experience regarding the use of microvascular free flaps for reconstruction of the anterior or middle skull base after large defects caused by removal of malignant neoplasms. From 2000 to 2004, in the Department of Maxillo-Facial Surgery of the University of Rome "La Sapienza" and "Tor Vergata," 13 surgical procedures for reconstruction of anterior and middle skull base defects by free flaps were performed in 11 patients. Data on patient demographics, histopathology, location and size of defect, type of reconstruction, and postoperative complications were obtained from medical record charts. A safe soft tissue closure of the intracranial space was achieved in all patients. Defect repair was accomplished by revascularized transfer of rectus abdominis flaps in seven cases, latissimus dorsi muscle flaps in two patients, radial forearm flap in one case, and fibula flap in one case. There were two total flap losses; the secondary defect repair was accomplished in both cases by revascularized transfer of latissimus dorsi muscle flap. No donor site complications were observed in all the flaps. The mean operation time was 85 hours; patients were hospitalized for a mean period of 14 days. The method of choice for the reconstruction of anterior or middle skull base defect should be based upon careful evaluation of the single case and, particularly, the localization and entity of the residual defect. For defects that require large amounts of soft tissue, the latissimus dorsi free flap and the rectus abdominis free flap are the best appropriate choices for reconstructive procedures for anterior and middle skull base tumors.
Loss of autofluorescence as an early phenomenon associated with tissue degeneration seems to be promising for the diagnosis of oral cancer. The method seems to make visible early structural and biochemical alterations of the oral mucosa not always evident under direct inspection of the oral cavity. For this reason, the margins of the mucosal lesions usually appear wider compared with direct visualization. Actual extension of the potentially malignant lesions must be precisely perceived to avoid any underestimation of the tumor. In this study, 32 patients at risk for oral cancer underwent autofluorescence test. Of these patients, 12 (group A) experienced potentially malignant diseases. The other 20 patients (group B) were previously operated on for oral cancer. In addition, 13 patients showed loss of autofluorescence (8 patients from group A and 5 patients from group B). Among these 13 patients, 12 were affected with lesions of relevance (in group A, 6 had squamocellular carcinoma and 2 had low-grade dysplasia; in group B, 2 patients had high-grade dysplasia, 2 had low-grade dysplasia, and 1 had an epithelial hypertrophy with inflammatory cells). Preliminary results seem to indicate that autofluorescence is a high-performing test for the individuation of oral cancer in populations at risk (sensibility up to 100% and specificity up to 93% in this study).
