[Ab] Resumo:The zygomatico-maxillary complex functions as the principle buttress of the face and is the cornerstone to an individual’s aesthetic appearance. Its fracture not only creates cosmetic deformities owing to its position and facial contour, but can also cause disruption of ocular and mandibular functions. The aim of this study was to evaluate the quality, efficacy and impact of internal fixation of zygomatic complex fractures on functional and cosmetic outcomes. A prospective study was carried out on 100 patients who were divided according to the classification and the severity of injury. Subjective evaluation was submitted based on the patient’s perception of signs and symptoms in the preoperative and postoperative periods. Intraoperative and postoperative assessment of bone reduction quality was made according to the type of the fracture and related difficulties; also, the difference between these groups was observed as functional and esthetic outcome. To optimize the treatment of zygomatic bone fractures, a pre-designed questionnaire was used for subjective evaluation of symptoms and treatment outcome. In 70% of cases, ophthalmologic consultation was taken and was most common in type VII fractures (100% cases). Neurosensory disturbance was the most common finding (60%), followed by diplopia (56R%), pain upon mouth opening (54%) and malar depression (50%). Out of all possible 400 fracture sites in 100 patients of zygomatic complex fractures, 266 (66.5%) fractures were detected by clinical examination, in contrast to 330 (82.5%) on radiological examination, which were highest at zygomatic-maxillary buttress (93%) followed by infraorbital rim (91%) and almost equal among fronto-zygomatic site (72%) and zygomatic arch (74%). The scores from the questionnaire for annoyance were significantly higher for paraesthesia (23%) than for trismus (10%), pain (8.5%), or deformity (8.25%). Residual deformity and pain significantly influenced the total satisfaction. Conclusively, there are many treatment modalities available for zygomatic complex fractures, and the preferred methods should be selected on the basis of fracture type, fracture severity, pre-operative signs and symptoms. Regarding the requirements of fracture site exposure and actual fixation, one priority should be to minimize postoperative complications, morbidity and residual deformities.

[Ab] Resumo:INTRODUCTION: Goldenhar syndrome is a rare disease with hemifacial microsomia and craniofacial disorders originating from the first and second branchial arches, such as ocular, auricular, and vertebral anomalies. The complexity and variety of the ways in which the disease presents itself usually need several examinations. In this study, we aimed to evaluate both craniofacial and vertebral skeletal anomalies and asymmetries between the nonaffected and affected sides in patients with Goldenhar syndrome by using cone-beam computed tomography. METHODS: Ten patients (7-14 years old; 6 boys, 4 girls) were evaluated via NewTom 5G cone-beam computed tomography (QR srl, Verona, Italy) with a large field of view (18 × 16 cm). Ten anatomic facial landmarks were identified to measure the following distances bilaterally: sella turcica (ST)-mandibular angle, ST-condyle, ST-mastoid, ST-mental foramen, ST-fronto zygomatic suture, ST-zygomatic temporal suture, ST-zygomatic facial foramen, ST-sphenopalatine fossa, mandibular angle-mandibular symphysis, and mandibular angle-condyle. The following 6 volumes were calculated bilaterally: orbit, maxillary sinus, condyle, external ear canal, middle ear, and internal auditory canal. These measurements were performed to assess skeletal asymmetries to compare the nonaffected side with the affected side by the Wilcoxon test. Cervical spine anomalies were classified into fusion anomalies and posterior arch deficiencies. RESULTS: All patients showed a deficit of skeletal development on the affected side. Statistically significant differences (0.001 ≤ P value ≤ 0.043) between the nonaffected and affected sides were recorded for all measurements, except for ST-frontozygomatic suture, mandibular angle-mandibular symphysis, and maxillary sinus volume. Vertebral fusion anomalies and posterior arch deficiencies were found in 7 and 4 patients, respectively. CONCLUSIONS: Cone-beam computed tomography with a large field of view was able to accurately identify craniofacial and vertebral skeletal anomalies, and to quantify asymmetries between the nonaffected and affected sides for an efficient maxillofacial treatment planning.

[Ab] Resumo:INTRODUCTION: Primitive neuroectodermal tumors of peripheral origin are very rare, and orbital neuroectodermal tumors are even more uncommon. Only 25 patients with primary orbital involvement in the pediatric age group have been reported. METHODS: In this article, the authors describe their experience in the multimodality treatment approach to treat neuroectodermal tumor of the orbit. The authors also present a male patient 3-year old presenting with a neuroectodermal tumor of the right orbit causing rapidly progressive proptosis. The patient underwent an upper and lateral orbital marginotomy. The entire bone defect was reconstructed with a bone graft, allowing for the reconstruction of the floor and the lateral wall of the middle cranial fossa, the floor of the anterior cranial fossa, the upper and lateral orbital frame, and the right zygomatic bone. Over a period of 16 months, the patient was subjected to chemotherapy. RESULTS: In the postoperative period, a favorable evolution of the disease was observed, with growth in the reconstructed structures, good projection of the orbit and the eyeball, and stable results without tumor recurrence. CONCLUSIONS: The authors present the clinical analysis, surgical management, as well as the chemotherapy treatment established, with follow-ups at 1 and 2 and a half years. This experience shows the effectiveness of multimodality therapy in the treatment of rare tumors of difficult handling.

[Ti] Título:Negative regulation of endothelin signaling by SIX1 is required for proper maxillary development.

[Ab] Resumo:Jaw morphogenesis is a complex event mediated by inductive signals that establish and maintain the distinct developmental domains required for formation of hinged jaws, the defining feature of gnathostomes. The mandibular portion of pharyngeal arch 1 is patterned dorsally by Jagged-Notch signaling and ventrally by endothelin receptor A (EDNRA) signaling. Loss of EDNRA signaling disrupts normal ventral gene expression, the result of which is homeotic transformation of the mandible into a maxilla-like structure. However, loss of Jagged-Notch signaling does not result in significant changes in maxillary development. Here we show in mouse that the transcription factor SIX1 regulates dorsal arch development not only by inducing dorsal expression but also by inhibiting endothelin 1 ( ) expression in the pharyngeal endoderm of the dorsal arch, thus preventing dorsal EDNRA signaling. In the absence of SIX1, but not JAG1, aberrant EDNRA signaling in the dorsal domain results in partial duplication of the mandible. Together, our results illustrate that SIX1 is the central mediator of dorsal mandibular arch identity, thus ensuring separation of bone development between the upper and lower jaws.

[Ab] Resumo:INTRODUCTION: In this article, we aimed to establish an ideal definition for the craniofacial midsagittal plane (MSP) by first finding an optimal "plane of best fit" and then deriving a simple approximation for clinical use that is highly accurate. METHODS: For 60 adolescent patients, 3-dimensional coordinates of 8 central landmarks and 6 pairs of lateral landmarks were collected. Across all patients, the coplanarity of the central landmarks was compared with that of the midpoints of the lateral landmarks. The MSP of best fit was then found by minimizing the mean square distance of the 8 central landmarks to a plane. Across all patients, each possible 3-point plane was compared with the MSP of best fit with respect to both orientation and proximity. RESULTS: The central landmarks were more coplanar and thus more accurate than the midpoints of the lateral pairs. The plane defined by nasion, basion, and incisive foramen was the closest to the MSP of best fit in both orientation and proximity. CONCLUSIONS: The nasion-basion-incisive foramen plane should be used for skull orientation and 3-dimensional cephalometric analyses because it approximates the MSP of best fit with high accuracy, avoids the use of horizontal reference planes, avoids influence from upper and midface asymmetry, uses easily identifiable relevant landmarks, and is simple to define.

[Ti] Título:Preserving the Facial Nerve During Orbitozygomatic Craniotomy: Surgical Anatomy Assessment and Stepwise Illustration.

[Ab] Resumo:OBJECTIVE: Surgical safety and efficiency during an orbitozygomatic (OZ) osteotomy rely on thorough knowledge of the surgical anatomy of the facial nerve. Although the anatomy of the facial nerve and its relation to the pterional craniotomy are described, a thorough assessment of facial nerve preservation techniques during the OZ approach and its variations is lacking. We assessed the surgical anatomy of the facial nerve related to the OZ approach and provided a thorough stepwise description on how to preserve it. METHODS: The OZ approach was performed bilaterally in 15 cadaveric heads. The interfascial and subfascial techniques were performed to study their nuances in preserving the facial nerve. We compared the 2 techniques and provided a thorough description on how to preserve the facial nerve during each step of the OZ approach. RESULTS: At the zygomatic arch, the facial nerve was found between the galea and the superficial temporal fascia. A cut in the fascia at the posterior end of the zygomatic arch did not cross any facial nerve branches. The subfascial technique was simpler, more efficient, and provided more structural protection of the facial nerve branches than the interfascial technique. CONCLUSIONS: The frontal division of the facial nerve is related directly to dissection over the zygomatic bone and may be injured during fascial dissection or osteotomies. Both interfascial and subfascial techniques are feasible to use during the OZ craniotomy and provide ample exposure of the OZ unit. Regarding the preservation of the facial nerve branches, we favor the subfascial method.

[Ab] Resumo:PURPOSE: To compare the outcome of site preparation for zygomatic oncology implants using conventional preparation with rotary drills or piezoelectric surgery with dedicated inserts for placing two zygomatic implants per zygoma according to a split-mouth design. MATERIALS AND METHODS: Twenty edentulous patients with severely atrophic maxillas not having sufficient bone volume for placing dental implants and less than 4 mm of bone height subantrally had their hemi-maxillas randomised according to a split-mouth design into implant site preparation with conventional rotational drills or piezoelectric surgery. Two zygomatic oncology implants (unthreaded coronal portion) were placed in each hemi-maxilla. Implants that achieved an insertion torque superior to 40 Ncm were immediately loaded with screw-retained metal reinforced acrylic provisional prostheses. Outcome measures were: prosthesis and implant failures, any complications, time to place the implants, presence of post-operative haematoma, and patient's preference by independent assessors. All patients were followed up to 1 year after loading. RESULTS: In two patients drills had also to be used at the piezoelectric surgery side to enable implant sites to be prepared. One implant for the conventional drill group did not achieve an insertion torque superior to 40 Ncm since it fractured the zygoma. No patients dropped out and two distal oncology implants failed in the same patient (one per group), who was not prosthetically rehabilitated. Six complications occurred at drilled sites and three at piezoelectric surgery sites (two patients had bilateral complications), the difference being not statistically significant (P (McNemar's test) = 0.375; odds ratio = 4.00; 95% CI of odds ratio: 0.45 to 35.79). Implant placement with convention drills took on average 14.35 ±â€…1.76 min and with piezoelectric surgery 23.50 ±â€…2.26 min, implant placement time being significantly shorter with conventional drilling (difference = 9.15 ±â€…1.69 min; 95%CI: 8.36 to 9.94 min; P < 0.001). Post-operative haematomas were more frequent at drilled sites (P = 0.001), and 16 patients found both techniques equally acceptable, while four preferred piezoelectric surgery (P = 0.125). CONCLUSIONS: Both drilling techniques achieved similar clinical results, but conventional drilling required 9 min less and could be used in all instances, although it was more aggressive. These results may be system-dependent, therefore they cannot be generalised to other zygomatic systems with confidence. Conflict-of-interest statement: This study was partially supported by Southern Implants (Irene, South Africa), the manufacturer of the zygomatic implants and the conventional drills evaluated in this study. However, data property belonged to the authors and by no means did the manufacturer interfere with the conduct of the trial or the publication of its results. Drs Felice and Pistilli developed the piezoelectric surgery zygomatic insert used in the present study.

[Ab] Resumo:BACKGROUND: Biodegradable fixation systems could reduce or eliminate problems associated with titanium removal of implants in a second operation. AIM: The aim of this study was to compare the long-term (i.e. >5 years postoperatively) clinical performance of a titanium and a biodegradable system in oral and maxillofacial surgery. MATERIALS AND METHODS: The present multicenter Randomized Controlled Trial (RCT) was performed in four hospitals in the Netherlands. Patients treated with a bilateral sagittal split osteotomy (BSSO) and/or a Le Fort-I osteotomy, and those treated for fractures of the mandible, maxilla, or zygoma were included from December 2006 to July 2009. The patients were randomly assigned to either a titanium (KLS Martin) or a biodegradable group (Inion CPS). RESULTS: After >5 years postoperatively, plate removal was performed in 22 of the 134 (16.4%) patients treated with titanium and in 23 of the 87 (26.4%) patients treated with the biodegradable system (P = 0.036, hazard ratio (HR) biodegradable (95% CI) = 2.0 (1.05-3.8), HR titanium = 1). Occlusion, VAS pain scores, and MFIQ showed good and (almost) pain free mandibular function in both groups. CONCLUSION: In conclusion, the performance of the Inion CPS biodegradable system was inferior compared to the KLS Martin titanium system regarding plate/screws removal in the abovementioned surgical procedures.

[Ab] Resumo:BACKGROUND: The various approaches to reduction and fixation of isolated displaced zygomatic arch fractures have not been well studied. The authors compared established treatment methods for zygomatic arch fractures for both aesthetic and functional outcomes. METHODS: Consecutive patients with isolated zygomatic arch fractures with a minimum of 6 months' follow-up were studied in five groups: group 1, intraoral approach (no fixation); group 2, temporal approach (no fixation); group 3, coronal flap plate fixation; group 4, external splint fixation; and group 5, no surgery. Perioperative complications, facial contour symmetry (aesthetic outcome), improvement in mouth opening (functional outcome), and reoperations were compared. RESULTS: Patients undergoing external splint fixation had no perioperative complications. Coronal flap plate fixation had the highest rate of perioperative complications (46 percent), with facial nerve injury (4 percent), hematoma (8 percent), and persistent hyperesthesia (8 percent). Reoperations (fat grafting or bony reconstruction) were highest with coronal flap plate fixation (23 percent) and the temporal approach (7.7 percent); external splint fixation and the intraoral approach required no reinterventions. Patients treated with external splint fixation had the largest improvement in mean interincisor mouth opening. Mean postoperative interincisor opening in decreasing order was as follows: external splint fixation (51.6 mm), coronal flap plate fixation (47.1 mm), no surgery (39.8 mm), intraoral approach (39.6 mm), and temporal approach (38.9 mm). The highest volumetric symmetry was seen in external splint fixation (97.9 percent), followed by coronal flap plate fixation (94 percent), temporal approach (76.2 percent), intraoral approach (73 percent), and no surgery (68.3 percent). CONCLUSION: For isolated zygomatic arch fracture, patients undergoing external splint fixation had the lowest risk of perioperative complications and the greatest improvement in functional and aesthetic outcomes compared with the intraoral approach (no fixation), the temporal approach (no fixation), coronal flap plate fixation, and no surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.
