Free fat transplantation for facial tissue augmentation.

PURPOSE: This article reviews the lipofilling technique using a fat tissue suspension obtained by manual or vacuum machine-assisted suction. PATIENTS AND METHODS: Between 1989 and 1997 14 patients were treated by lipofilling. All patients were female; 6 were treated for cheek and zygomatic area augmentation for Romberg syndrome (2 cases) and bilateral facial lipodystrophy (4 cases); 4 were treated for nasolabial fold correction, 3 for lip augmentation, and 1 for correction of systemic lupus erythematosus (LES) scars. RESULTS: Good results were obtained in the treatment of the moderate Romberg syndrome case, with 3 stages of fat tissue transplantation from the abdominal area, in the severe Romberg syndrome case that was treated with 3 stages of lipofilling after a primary surgical procedure consisting of augmentation of the zygomatic region using a composite temporal flap of calvaria bone and temporal muscle, in the 4 cases of bilateral facial lipodystrophy, and in the 4 cases of nasolabial fold correction with 3 to 4 stages of lipofilling. Poor results were obtained in lip augmentation, and bad results were obtained in correction of the LES scars. CONCLUSIONS: Using the lipofilling technique with cannulas of 3 to 4 mm in diameter and low-power manual aspiration to preserve the integrity of the fat cells, good results were achieved in 10 of the 14 patients treated. The poor results occurred in areas of reduced vascularity and high motility.

[Postoperative treatment of alcohol withdrawal syndrome in a patient operated for oral cancer].

A case of alcohol withdrawal occurred in a patient affected by cancer of the oral cavity is reported. The patient underwent resection of the floor of the oral cavity, partial glossectomy mandibulectomy and neck dissection; reconstruction was done using microsurgical forearm radial flap. The patient didn't refer his alcohol dependence before operation and withdrawal symptoms with agitation, tachycardia, tachypnea, tremors and vomiting appeared during his postoperative recovery in intensive care where the patient was unable to take any alcohol. A therapeutic plan to use in patients operated for oral cancer with alcohol withdrawal (92% association of oral cancer with alcohol dependence) is reported.

[Microsurgical reconstruction of the mandible].

The authors present two clinical cases of mandibular reconstruction using free vascularized bone grafts and dental osseointegrated implants. A wide discussion about the different techniques of reconstruction is reported. Several factors like the clinical history, age, general conditions of patient's health can influence the choices of the surgeon. The characteristics of the different donor sites are described, so the advantages and disadvantages of the different free microvascular flaps are analyzed. According to the authors not only the technical aspects of microsurgery but also a good choice of the right free flap plays an important role in a successful result. The influence of radiotherapy on microvascular reconstruction in the head and neck region is also discussed. The authors recommend the use of fibula and scapula as donor site for reconstruction of complex (i.e. interesting also the adjacent soft tissues, muscles, mucosa and skin) mandibular defects that require more than 6 cm of bone graft length. Corticotomies of bone ensure a perfect adaptation of the graft to the mandibular form with a good aesthetic result, while the use of dental osseointegrated implants allows total masticatory functional rehabilitation. It's important that these techniques must be utilized in well organized hospital centers by experienced surgeons who are able to resolve entirely the problems and needs of the patient.

[The role of autologous parietal bone graft in alveolar cleft].

Autologous bone grafting of alveolar clefts is a well recognized procedure. Calvarium represents an interesting donor site because of the absence of morbidity and the dimensional stability of this membranous bone compared with endochondral bone sources. The authors reponed their experiences with this type of grafting used in 17 patients. Referred to the parameters analized in an important Swedish study, the rate of success was about 80% agree with the results of other authors with the same type of graft. Aspects of general planning, timing, technique and failure are extensively discussed. Pre and post surgical orthodontic treatment is also very important for a good result. The pattern of maxillo-facial growth and the effect of the graft materials on facial development are mentioned. The study of literature indicates that the best grafting results are achieved when free autogenous mandibular symphyseal bone grafts were used. The only true disadvantage is the small quantity of bone tissue available. The authors conclude suggesting the use of chin bone grafting in situations where the technique provides sufficient bone and recommend the use of cranial vault as the alternative source of membranous bone graft, for example, in bilateral clefts, when anterior theeth are not erupted yet and in any other situation where the mandibular bone graft is not possible.

[The advantage of the autologous parietal bone graft in posttraumatic rhinoplasty].

Popularized by Tessier in 1982, the calvarial bone graft has been used extensively in reconstructive techniques in the cranio-facial region. The authors present here their experience of nasal bone grafting using split skull grafts for post-traumatic reconstructions. Ten patients, with a total of 11 bone grafts harvested, were operated. Results are reported. The level of patient satisfaction has been high. We have had only 2 minor complications, 1 case of alopecia, corrected by a resection in local anesthesia, this inconvenient has never reported before in the literature, and another case of secondary displacement of the nasal bone graft, who required a second operation with a good result. Discussion is reported. Several methods have been used for nasal reconstruction as silicone implants and other bone donor site; but they have disadvantages like painful to the donor site, long hospitalizations, infections and extrusions, etc. The use of cranial graft has some advantages: first of all, it is less likely to resorb, because of its membranous origin, the donor site is in close proximity to the area to be grafted, there is almost no morbidity to the donor site. Recently two case reports describing major complications were published in the literature. A case of a superior sagittal sinus laceration reported by Cannella and Hopkins and a case of an intracerebral hematoma, reported by Leroy-Young. For these reasons it's important to follow strictly the surgical procedure described. We recommended this technique only to those surgeons who are experienced in cranio-facial surgery.

[The cancerous recurrence of a pleomorphic adenoma of the parotid. Comments on a case].

After taking the clinical case examined as a starting point and supporting the data obtained with a literature analysis of the cancerous relapse of a parotid pleomorphic adenoma, the Authors suggested a suitable surgical operation (total parotidectomy with conservation of the facial nerve) in the treatment of parotid pleomorphic adenoma. Doing so, it is possible to avoid a relapse of neoplasm and a possible transformation into malignancy. Furthermore it might prevent the formation of parotid carcinoma.

[Cervicofacial actinomycosis. A case study].

A case of cervicofacial actinomycosis, sited in the central hyoid region, is reported. The Authors have emphasized the difficulties of the diagnosis. It's very important hat the clinical diagnosis of actinomycotic infection be confirmed by a positive culture test. Actinomycosis can be suspected if multiple recurrent pustular swellings are present, associated with any trauma or teeth extractions.
