The free osteofasciocutaneous fibula flap: clinical applications and surgical considerations.

INTRODUCTION: The aim of this study was to investigate the intraoperative findings, postoperative complications, donor site morbidity and patients' Quality of Life in order to evaluate the usefulness of the free osteofasciocutaneous fibula flap in the reconstruction or construction of a mandibula, neophallus, lower leg or forearm. MATERIALS AND METHODS: 104 patients were treated with free osteofasciocutaneous fibula flaps in our clinic. 23 for mandible reconstruction, 66 for neophallus reconstruction, 9 for lower leg reconstruction and 6 for forearm reconstruction. These patients were asked to answer a questionnaire and to be present for a clinical and a radiological examination in our department. In addition, their previous records were evaluated retrospectively. RESULTS: The dimension of the surface of the skin island was 178.6 cm(2) (72-352 cm(2)) in average and the average length of the fibular bony part was 15.4 cm (10-23 cm). The most frequent and severe complication was skin island edge necrosis (n=7); no total flap necrosis was found. Donor-site morbidity was low, since no joint instability could be reported. Quality of Life was improved according to the standardised FLZ(M) questionnaire. CONCLUSION: Advantages of free osteofasciocutaneous fibula flaps were the wide cortical bone and the relative constant anatomy, the long pedicle, flat, uniform and sufficient large and pliable skin island, as well as the good blood circulation also by massive modelling of the skin and bone part. The skin island could be harvested large enough in order to reconstruct extended soft-tissue defects in the face and the extremities as well as to construct neophallus in its normal size without any restrictions. The lower leg donor-site morbidity was moderate and can be readily covered with a sock in patients' everyday life common activities. Finally, in our hands, the utilisation of the free osteofasciocutaneous fibula flap is the best possible therapy for these difficult composite reconstructions.

A review of 13 years of experience with endoscopic forehead-lift.

OBJECTIVE: To conduct objective quantitative and qualitative evaluations of the long-term result in endoscopic forehead-lift. METHODS: Medical charts of 143 patients who underwent endoscopic forehead-lift between 1994 and 2007 were reviewed for postoperative complications and the duration of complaints. Patients received a questionnaire to evaluate satisfaction and social restriction after surgery. Objective photographic preoperative and postoperative eyebrow-to-eye distances in a relaxed position and during muscle contractions were obtained. RESULTS: A total of 98 patients (69% response; mean follow-up, 38 months) showed high satisfaction (score, 7.1 of 10). In a relaxed position, mean midpupil-to-eyebrow elevation was 5.6 mm after surgery, with significant eyebrow symmetry between the left and right eyes (P < .05), and showed significant influence of time (P = .005) on persisting eyebrow elevation, with a decrease of almost 1 mm per year. Measurements during muscle contraction showed no relevant differences. CONCLUSION: Endoscopic forehead-lift enables long-lasting results with highly satisfied patients.

Does abdominoplasty have a positive influence on quality of life, self-esteem, and emotional stability?

BACKGROUND: In a previous prospective study, the authors evaluated the quality of life in patients undergoing aesthetic surgery. In this survey, the authors split up the operative indication and analyzed quality of life, self-esteem, and emotional stability after abdominoplasty alone. METHODS: Sixty-three patients participated in the study. The testing instrument consisted of a self-developed questionnaire to collect demographic and socioeconomic data and a postoperative complication questionnaire developed especially for abdominoplasties. In addition, a standardized self-assessment test on satisfaction and quality of life (Questions on Life Satisfaction), the Rosenberg Self -Esteem Questionnaire, and the Freiburg Personality Inventory were used. RESULTS: Significantly increasing values in some items of the standardized self-assessment test on satisfaction and quality of life were found: sum scores of the General Life Satisfaction showed a significant improvement (p = 0.004) and the scores of the items housing/living conditions (p = 0.000) and family life/children (p = 0.000). Within the Satisfaction with Health module, a significant improvement in the items mobility (p = 0.02) and independence from assistance (p = 0.01) was found. Values in the module Satisfaction with Appearance (Body Image) increased regarding satisfaction with the abdomen (p = 0.001). Over 84 percent were very satisfied with the aesthetic result, 93.4 percent would undergo the same treatment again, and 88.9 percent would further recommend the operation. Data revealed that participants' self-esteem was very high and their emotional stability was very well balanced. CONCLUSIONS: This study demonstrates that abdominoplasty increases most aspects of quality of life, particularly family life, living conditions, mobility, and independency from assistance. Also, patient self-esteem and emotional stability ratings are very high postoperatively.

Three-dimensional evaluation of breast augmentation and the influence of anatomic and round implants on operative breast shape changes.

BACKGROUND: Currently, postoperative outcome analysis in breast augmentation is essentially subjective, and objective evaluation of treatment efficacy is lacking. This study evaluates the influence of anatomic and round implant parameters on breast contour changes after subpectoral breast augmentation using three-dimensional (3D) surface imaging. METHODS: 3D surface breast scans of 17 patients (34 breasts) undergoing subpectoral breast augmentation with round implants and of ten patients (20 breasts) receiving anatomic implants via an axillary approach under endoscopic assistance or a submammary fold incision were obtained before and 6 months postoperatively. 3D linear distance, breast volume, and surface measurement were correlated with the implanted round and anatomic implant parameters, and the resulting breast shape changes were evaluated. RESULTS: Total breast volume changed in correlation with the implant size (2.4% difference; r=0.894; p<0.001). Implant volume and type influence the nipple-to-inframammary fold distance (N-IMF). Every inserted 100 ml implant volume enlarges the N-IMF distance by 0.8 cm (anatomic>round; p=0.01). Postoperatively, the IMF dropped by an average of 1.3 cm for round implants and by 1.1 cm for anatomic implants, without relevant differences between the applied surgical incision and the selected implants (p>0.05). Breast projection increased significantly more with anatomic implants (2.4 cm) than with round implants (1.7 cm) (p=0.01). The breast projection increase was 22% less than expected for round implants and 25% less than expected for anatomic implants based on the manufacturer implant parameters (p<0.01), without essential differences regarding the surgical incision. CONCLUSIONS: 3D breast shape changes induced by round and anatomic implants after subpectoral augmentation mammaplasty are objectively documented including breast projection, volume, and N-IMF distance changes. 3D surface imaging may have a potential clinical contribution to objective surgical outcome research.

Peripheral nerve reconstruction with collagen tubes filled with denatured autologous muscle tissue in the rat model.

Conventional nerve conduits lack cellular and extracellular guidance structures critical for bridging larger defects. In this study, an exogenous matrix for axonal regeneration was provided by pretreated muscle tissue. In 24 rats, 14-mm sciatic nerve segments were resected and surgically reconstructed using one of the following methods: autograft (AG); bovine type I collagen conduit; (MDM) collagen tube filled with modified denatured autologous muscle tissue. For 8 weeks, functional regeneration was evaluated by footprint and video gait analysis. Evaluation was complemented by electrophysiology, as well as qualitative and quantitative structural assessment of nerves and target muscles. Group AG was superior both structurally and functionally, showing higher axon counts, a more normal gait pattern, and less severe muscle atrophy. Fiber quality (fiber size and myelin thickness) was highest in group MDM, possibly related to the myelin-producing effect of muscular laminin. However, axon count was lowest in this group, and ultrastructural analysis of the denatured muscle tissue showed areas of incomplete denaturation that had acted as a mechanical barrier for regenerating axons. In light of these results, the often advocated use of muscular exogenous matrix for peripheral nerve reconstruction is reviewed in the literature, and its clinical application is critically discussed. In conclusion, combined muscle tubes may have a positive influence on nerve fiber maturation. However, muscle pretreatment is not without risks, and denaturation processes need to be further refined.

Three-dimensional evaluation of breast contour and volume changes following subpectoral augmentation mammaplasty over 6 months.

BACKGROUND: Changes in breast-morphology occur after all types of breast surgery, but a systematic and objective surgical result assessment is currently lacking. Three-dimensional (3-D) surface imaging offers the ability to quantitatively evaluate breast contour, shape, surface and volume changes after surgery. This study evaluates 3-D breast contour and volume changes after breast augmentation over time. METHODS: 3-D surface imaging of 14 subpectoral breast-augmentation patients (n = 28 breasts) were accomplished over six time periods (preoperative (OP), post-OP 1: 2-3 days; post-OP 2: 1 week; post-OP 3: 1 month; post-OP 4: 3 months; and post-OP 5: 6 months after surgery) and linear-distance measurement, breast volume and surface changes were analysed. 3-D breast-contour- and volume variations are expressed in percentage changes over time. RESULTS: All breast measurements changed significantly between pre-OP and post-OP 1 (Friedmann test, p = 0.001-0.025). First significant postoperative changes over time compared with post-OP 1 for breast volume, surface, sternal notch to nipple and nipple to inframammary-fold-distance measurements are quantifiable after 1 month (post hoc Wilcoxon test, p = 0.001 for all) with further relevant breast volume (post hoc Wilcoxon test, p = 0.041) and surface changes (post hoc Wilcoxon test, p = 0.037) between months 1 and 3 after surgery. The inframammary fold dropped by 1.4 cm after 6 months and final breast volume ± 0.5% is reached between months 1 and 3 after surgery. Valuable reductions in breast contour and volume by nearly 85% are also reached after 1 month (Wilcoxon test, p = 0.001) and changed to 98% after 3 months and 100% after 6 months. CONCLUSIONS: Breast morphological changes following subpectoral breast augmentation are completed after 3 months. 3-D surface imaging may play a part in comparing different breast-augmentation techniques.

Women's quality of life and surgical long-term outcome after breast reconstruction in Poland syndrome patients.

BACKGROUND: In the last decades, several surgical approaches have been used to improve the appearance and quality of life of female Poland syndrome patients. The aim of this study was to analyze the women's quality of life and long-term outcome after breast reconstruction. METHODS: Forty-nine women with Poland syndrome who were treated surgically between 1974 and 2007 received standardized questionnaires to evaluate their quality of life and satisfaction after surgical treatment. RESULTS: Patient response was 65%, with 32 completed questionnaires by 16 women who had pedicled latissimus dorsi myocutaneous (LDM) flaps, 12 with tissue expander or silicone implants, and 4 who had free transverse rectus abdominis myocutaneous (TRAM) flaps. Of these patients, 16 were satisfied or highly satisfied with their postoperative appearance (13 with LDM, 2 with prosthesis, and 1 with TRAM), 16 patients would recommend the same surgery to others under similar circumstances (10 with LDM, 5 with prosthesis, and 1 with TRAM), and 18 patients would choose the same method again (14 with LDM, 3 with prosthesis, and 1 with TRAM). CONCLUSIONS: In our study, we found that satisfactory outcome in breast reconstruction was achieved particularly when using the LDM flap, which remains the only method that recreates the anterior axillary fold. Future studies on reconstruction methods with autogenous tissue (e.g., TRAM, deep inferior epigastric perforator [DIEP] flap) are needed, however, to analyze quality of life and long-term outcome in patients with Poland syndrome.

Successful anatomic repair of fetoscopic access sites in the mid-gestational rabbit model using amnion cell engineering.

BACKGROUND/AIM: Our aim was to evaluate the impact of in vitro cultured amnion cells, injected and/or seeded in different scaffolds, on in vivo fetal membrane repair. MATERIALS AND METHODS: Amnion cells, isolated from allogeneic fetal membranes, were cultured on three different scaffolds for 14 to 21 days. In 33 mid-gestational rabbits, fetoscopic access sites were randomly allocated to four closure study groups: conventional collagen plug, as well as collagen plug, collagen foil, and fibrin glue as scaffolds for the cultured amnion cells. All membrane access sites were sealed with fibrin glue, and the myometrium closed with sutures. Fetal survival, amnion membrane integrity, and the presence of amniotic fluid were evaluated one week later. RESULTS: Cultures showed good survival in the collagen scaffolds. The use of collagen plug as a scaffold for the in vitro cultured amnion cells improved the integrity of fetal membranes to 80%, better than that of any other study group. CONCLUSION: Despite the need for additional studies, the present data suggest that amnion cells can be a practical and important source of cells for the engineering of constructs for sealing of the fetal membrane.

Searching for the right timing of surgical delay: angiogenesis, vascular endothelial growth factor and perfusion changes in a skin-flap model.

BACKGROUND: The angiogenic potential of vascular endothelial growth factor (VEGF) and its oxygen pressure-dependent regulation suggest a strong connection between this growth factor and the 'delay phenomenon'. In this study we focused on the chronological changes in VEGF concentration and flap perfusion in order to optimise the duration of surgical delay. METHODS: The VEGF concentration in skin and underlying muscle was measured in oversized, random-pattern flaps on 38 male Sprague-Dawley rats after 3, 5 or 7 days of surgical delay. Additionally, flaps were raised 5 or 7 days past preconditioning. The effect on flap perfusion was measured using indocyanine green fluoroscopy and the size of surviving and necrotic areas of the flaps were analysed. Microvessel density was assessed using a monoclonal CD31 antibody, and vessel diameter and morphometry were appraised by means of corrosion casting. RESULTS: VEGF expression in the distal half of the flaps was significantly increased 3 days after preconditioning and perfusion was significantly enhanced after day 5. An interval of 5 days between preconditioning and flap transposition resulted in a significantly reduced average necrosis rate. Microvessel density was significantly increased and vessel diameters were enlarged (P<0.05). CONCLUSIONS: We illustrated the chronology of events from the ischaemic procedure to the rise in VEGF concentration and changes in flap perfusion, and demonstrated vasodilatation and the formation of new vessels. Most significantly, we were able to further specify the optimal length of surgical delay based on alterations on a molecular level as well as changes in vascularisation and perfusion.

The free vascularized fibular epiphyseal transfer: long-term results of wrist reconstruction in young patients.

To date, the dominant blood supply to the head of the fibula and to the growth plate is known to be the anterior tibial artery. The peroneal artery had been used before, among other donor pedicles, for microvascular transfers of this epiphyseal region. This study presents the long-term results of this now obsolete pedicle and compares them to other reports in the literature. Follow-up was performed in 1996 and in 2003 with six patients who underwent wrist reconstruction in the 1980s. Procedures were performed following one resection of a malignant synovialoma, two traumatic hand amputations, and three radial aplasias. Evaluation was performed with functional and radiographic examinations. Three cases that were examined in 2003 are presented in detail. The study shows that if growth plates are closed at the time of procedure or the transplanted fibula is long enough to ensure anastomotic flow between metaphyseal and epiphyseal vessels, results are good. If any of these two conditions is not fulfilled, vascular supply to the epiphysis is insufficient. Long bone deviation or bone necrosis will result. These results confirm clinically current knowledge about the epiphyseal and metaphyseal blood supply to the fibula.

Mandibular reconstruction with free osteofasciocutaneous fibula flap: a 10 years experience.

SUMMARY: The aim of this study was to evaluate the usefulness of the free osteofasciocutaneous fibular flap in mandible reconstruction in 23 patients. We reviewed their clinical records and asked the subjects to answer a questionnaire, as well as to attend our hospital for a clinical and radiological examination. The mean follow up was 1.3 years. In 15 patients, the flap was used for contemporaneous intraoral mucosal and extraoral cutaneous reconstruction. In seven cases, bilateral mandibular reconstruction was performed. Skin paddle edge necrosis was observed in seven flaps postoperatively, however, no total flap loss resulted. No additional soft-tissue flap was needed since the fibular flap harvested held an extended skin paddle reaching up to 352 cm(2). The donor-site morbidity was moderate and furthermore most of the patients were satisfied with their functional and aesthetic result. The free osteofasciocutaneous fibular flap is the best possible therapy for the demanding reconstruction of the mandible. The fibular bony part is a safe foundation for the placement of osseointegrated implants which further improves the patient's quality of life.

The use of free prelaminated and sensate osteofasciocutaneous fibular flap in phalloplasty.

SUMMARY: The aim of this study was to present our latest modified protocol on neophallus construction that we have applied in 32 female-to-male transsexuals. The applied protocol consisted of neourethra prelamination with split skin thickness grafting at the lateral donor lower leg, and neophallus construction after 6 months with the free, prelaminated, and sensate osteofasciocutaneous fibular flap, followed by urethro-urethral anastomosis. Because of initial difficulties on harvesting and positioning the fibular flap, we had 2 total and 4 partial necrosis. Ten patients had a urethral stricture, and 7 a fistula. In 6 patients a stricture expansion was required and in 5 closure of the fistula was needed. The donor-site morbidity was moderate. In conclusion, in our series this protocol proved to be the method of choice in this very demanding field of genitalia reconstructive surgery, offering an essential improvement of the quality of life of transsexual patients.

Fetoscopic closure of punctured fetal membranes with acellular human amnion plugs in a rabbit model.

OBJECTIVE: To explore a surgical plug formed from decellularized term human amnion membrane for fetoscopic closure of iatrogenic defects in fetal membranes in a rabbit model. METHODS: The study was performed in eight rabbit does. Punctures were created at midgestational day 23 by 14-gauge needle fetoscopy on surgically exposed rabbit amniotic sacs. The entry sites were fetoscopically plugged either with decellularized term human amnion membrane (n=10) or previously successful commercial collagen matrix foil (n=10), followed by their primary fixation with fibrin glue and myometrial suturing. Seven punctured sacs without any plugging and 31 sacs without any manipulation served as two reference groups. Amniotic integrity and fetal parameters were assessed at gestational day 30. RESULTS: We established a facile method to prepare sheets of decellularized term human amnion membrane and verified its nontoxicity and cell compatibility in vitro. Decellularized term human amnion membrane sheets could be delivered precisely and controlled by fetoscopy as compact plugs into amniotic defects. The surgical handling characteristics of decellularized term human amnion membrane were better than the commercial collagen matrix foil. Treatment with human decellularized term human amnion membrane was comparable to treatment with the collagen matrix with regard to efficiency in restoring amniotic integrity. Seventy-five percent and 71.4% of amniotic sacs treated with decellularized term human amnion membrane or the commercial collagen matrix foil, respectively, showed amniotic integrity, compared with 25% in the left-open study group. Histology at the 1 week experimental endpoint showed no evidence for inflammation or beginning of anatomic healing of grafted, decellularized term human amnion membrane. CONCLUSION: Fetoscopic delivery of plugs made of decellularized term human amnion membrane presents a potentially practical surgical method to restore amniotic integrity of punctured fetal membranes. LEVEL OF EVIDENCE: III.

Electrophysiologic assessment of sciatic nerve regeneration in the rat: surrounding limb muscles feature strongly in recordings from the gastrocnemius muscle.

Striking inconsistencies between the results of morphometric and electrophysiologic examinations of the regenerating nerve were observed in a previous study featuring the bridging of a 14 mm gap in the rat sciatic nerve. To shed light on this dichotomy, seven further rats were subjected to permanent sciatic nerve transection and assessed electrophysiologically, histologically and by retrograde axonal tracing at various postoperative intervals (1 h to 8 weeks). The results of the histological examinations and retrograde tracing revealed that in spite of the fact that compound muscle action potentials could be recorded in the gastrocnemius muscle, no reinnervation of the gastrocnemius muscle, either physiological or aberrant, had actually taken place. Furthermore, it was established that the electrical activity recorded in the gastrocnemius muscle after stimulation of the proximal or distal stump is generated by surrounding hind limb muscles unaffected by denervation. These are stimulated either directly, or indirectly due to spreading of the impulse. It is therefore strongly recommended that caution should be exercised when interpreting recordings from the gastrocnemius muscle after stimulation of a regenerating sciatic nerve in laboratory rodents.

Comparison between breast volume measurement using 3D surface imaging and classical techniques.

Quantification of the complex breast region can be helpful in breast surgery, which is shaped by subjective influences. However, there is no generally recognized method for breast volume calculation. Three-dimensional (3D) body surface imaging represents a new alternative for breast volume computation. The aim of this work was to compare breast volume calculation with 3D scanning and three classic methods, focusing on relative advantages, disadvantages, and reproducibility. Repeated breast volume calculations of both breasts in six patients (n=12) were performed using a 3D laser scanner, nuclear magnetic resonance imaging (MRI), thermoplastic castings, and anthropomorphic measurements. Mean volumes (cc) and mean measurement deviations were calculated, and regression analyses were performed. MRI showed the highest measurement precision, with a mean deviation (expressed as a percentage of mean breast volume) of 1.56+/-0.52% compared with 2.27+/-0.99% for the 3D scanner, 7.97+/-3.53% for thermoplastic castings, and 6.26+/-1.56% for the anthropomorphic measurements. Breast volume calculations using MRI showed the best agreement with 3D scanning measurement (r=0.990), followed by anthropomorphic measurement (r=0.947), and thermoplastic castings (r=0.727). Compared with three classical methods of breast volume calculation, 3D scanning provides acceptable accuracy for breast volume measurements, better spatial interpretation of the anatomical area to be operated on (due to lack of chest deformation), non-invasiveness, and good patient tolerance. After this preliminary study and further development, we believe that 3D body surface scanning could provide better preoperative planning and postoperative control in everyday clinical practice.

New aspects of breast volume measurement using 3-dimensional surface imaging.

Precise and objective calculation of breast volume is helpful to evaluate the aesthetic result of breast surgery, but traditional methods are unsatisfactory. Three-dimensional (3D) scanning of the body surface allows reproducible and objective assessment of the complex breast region but requires further investigation before clinical application. The main goal of this study was to investigate the precision and accuracy of breast volume measurement using 3D body scanning. Five independent observers standardized the 3D scanning method using 2 dummy models (n = 200) and examined its applicability with 6 test subjects and 10 clinical patients (n = 2220). Breast volume measurements obtained with the 3D-scanner technology were compared with reference measurements obtained from test subjects through nuclear magnetic resonance imaging. The mean deviation of the breast volume measurements of 1 test subject by all observers, expressed as percentage of volume, was 2.86 +/- 0.98, significantly higher than the deviation for the dummy models, 1.65 +/- 0.42 (P < 0.001). With respect to all clinical patients, the mean measurement precision obtained preoperatively was less precise than that obtained postoperatively (3.31 +/- 1.02 versus 1.66 +/- 0.49, respectively). Interobserver differences in measurement precision were not statistically significant. The mean breast volumes obtained by nuclear magnetic resonance imaging (441.42 +/- 137.05 mL) and 3D scanning (452.51 +/- 141.88 mL) significantly correlated (r = 0.995, P < 0.001). Breast volume measurement with 3D surface imaging represents a sufficiently precise and accurate method to guarantee objective and exact recording.

Amnion cells engineering: a new perspective in fetal membrane healing after intrauterine surgery?

In this study we aimed to set up an in vitro culture of the rabbit amnion in order to support in vivo fetal membrane healing capacity following fetoscopy. Fetal membranes were collected from a mid-gestational rabbit, and cultured on collagen support material for 14 days. 34 rabbits at 22-23 days gestational age (GA) underwent fetoscopy. The entry site was randomly allocated to 4 closure technique study groups: group I, human amnion membrane (n = 23); group II, collagen foil (n = 16); group III, collagen plug (n = 19), and group IV, collagen plug with cultured amnion cells (n = 19). In all groups membrane access sites were additionally sealed with fibrin sealant, and the myometrium was closed with sutures. Fetal survival, amnion membrane integrity, and the presence of amniotic fluid were evaluated at 30 days GA. Cultures showed good survival in the collagen support material. Increased cellularity, survival and proliferations were observed. The amnion at the access site resealed in 58-64% of cases in groups II-IV, but none of the tested techniques was significantly better than the other. Histological examination indirectly revealed the anatomic repair of the membranes, since no entrapment of the membranes could be demonstrated in the myometrial wound.

Optimization of 3-dimensional imaging of the breast region with 3-dimensional laser scanners.

The anatomic conditions of the female breast require imaging the breast region 3-dimensionally in a normal standing position for quality assurance and for surgery planning or surgery simulation. The goal of this work was to optimize the imaging technology for the mammary region with a 3-dimensional (3D) laser scanner, to evaluate the precision and accuracy of the method, and to allow optimum data reproducibility. Avoiding the influence of biotic factors, such as mobility, we tested the most favorable imaging technology on dummy models for scanner-related factors such as the scanner position in comparison with the torso and the number of scanners and single shots. The influence of different factors of the breast region, such as different breast shapes or premarking of anatomic landmarks, was also first investigated on dummies. The findings from the dummy models were then compared with investigations on test persons, and the accuracy of measurements on the virtual models was compared with a coincidence analysis of the manually measured values. The best precision and accuracy of breast region measurements were achieved when landmarks were marked before taking the shots and when shots at 30 degrees left and 30 degrees right, relative to the sagittal line, were taken with 2 connected scanners mounted with a +10-degree upward angle. However, the precision of the measurements on test persons was significantly lower than those measured on dummies. Our findings show that the correct settings for 3D imaging of the breast region with a laser scanner can achieve an acceptable degree of accuracy and reproducibility.

Three-dimensional cephalometric evaluation of maxillary growth following in utero repair of cleft lip and alveolar-like defects in the mid-gestational sheep model.

OBJECTIVE: To evaluate maxillary growth following in utero repair of surgically created cleft lip and alveolar (CLA)-like defects by means of three-dimensional (3D) computer tomographic (CT) cephalometric analysis in the mid-gestational sheep model. METHODS: In 12 sheep fetuses a unilateral CLA-like defect was created in utero (untreated control group: 4 fetuses). Four different bone grafts were used for the alveolar defect closure. After euthanasia, CT scans of the skulls of the fetuses, 3D reconstructions, and a 3D-CT cephalometric analysis were performed. RESULTS: The comparisons between the operated and nonoperated skull sides as well as of the maxillary asymmetry among the experimental groups revealed no statistically significant differences of the 12 variables used. CONCLUSIONS: None of the surgical approaches used for the in utero correction of CLA-like defects seem to affect significantly postsurgical maxillary growth; however, when bone graft healing takes place, a tendency for almost normal maxillary growth can be observed.
