[Ab] Resumo:RATIONALE: Primary osteosarcomas of the skull and skull base are rare, comprising <2% of all skull tumors. Primary osteosarcomas of the skull are aggressive neoplasms composed of spindle cells producing osteoid which have poor outcome. PATIENT CONCERNS: A 33-year-old woman was admitted to our hospital with a major complaint of a growing mass on her left frontal region of the skull for 10 months. Prior to the accurate diagnosis, the mass on her skull was considered to be eosinophilic granuloma. DIAGNOSES: Computerized tomogram (CT) scan of skull revealed a lytic lesion causing destruction of left frontal bone with surrounding soft tissue mass. The histological examination of the lesion showed typical features of osteosarcoma. INTERVENTIONS: The patient received 3 surgeries and adjuvant chemotherapy and radiotherapy for the frontal bone lesion. OUTCOMES: At the last follow-up, after 4 years, the patient was free of disease both clinically and on imaging by magnetic resonance imaging (MRI) scan after 4 years. LESSONS: Because osteosarcoma of skull is a rare disease, the early recognition and correct diagnosis are very important for a better prognosis. It is therefore imperative that clinicians recognize osteosarcoma early to make an accurate diagnosis and complete surgical resection followed by combined chemo-radiation is proved to be one of the most optimal treatment regimens.

[Ab] Resumo:Of all the craniofacial abnormalities, facial clefts are the most disfiguring. Facial clefts are classified according to the affected anatomical area as described by Tessier. Through this classification, the location and extent of the cleft can be designated numerically.A 2-month-old male infant was referred to authors' craniofacial unit, from a hospital in a rural province of South Africa, with a problem of a supranasal encephalocoele. Bilateral raised eyebrows were noted as was a right-sided upper lid central third coloboma. Computed tomography and magnetic resonance imaging scans confirmed the presence of a supranasal encephalocoele with a large frontal bone defect and splayed nasal bones. Bilateral enlarged orbits were noted with tented orbital roofs that we classified as Tessier number 10 facial clefts. The child was booked for an encephalocoele excision and calvarial reconstruction at 4 months of age.As a result of the encephalocoele, the supraorbital bar with its adjacent nasal bones was cleaved in 2, resulting in a significant frontal bone defect. Osteotomies were performed to remove the supraorbital bar and nasal bones from the calvarium. The supraorbital bar segment was remodeled and plated with absorbable poly-L-lactic acid plates. Osteotomies of the nasal bones allowed them to be united centrally, also with absorbable plates. This entire construct was transferred and secured to the calvarium, but in a more caudal position thereby obliterating the frontal bone and Tessier number 10 facial cleft defects with a naturally contoured construct.

[Ab] Resumo:OBJECTIVES: The objective is to describe a new surgical procedure developed in the San Jose Pediatric University Hospital for the management of syndromic synostosis of the metopic suture in a patient clinically diagnosed with Saethre-Chotzen syndrome. METHODS: The diagnosis of Saethre-Chotzen syndrome, bilateral coronal sutures, and metopic suture synostoses was made through photographic, anthropometric, exophthalmometric, and computed tomography analysis. The keel-like frontal bone deformity was corrected following resection using a fusiform osteotomy, remodelling was obtained by milling the edges, and the bony fragments were repositioned and fixed on the posterior wall of the frontal bone. Additionally, a fronto-orbital advancement with a self-stabilizing bar was performed. RESULTS: The 1-year postoperative results showed improvement in the position of the fronto-orbital bar, adequate cranial expansion, satisfactory correction of the upper facial third alteration, and correction of the keel-like deformity. CONCLUSIONS: The surgical approach has not previously been described in the literature and offers an alternative management for syndromic craniosyntostosis of the metopic suture, avoiding skull irregularities.

[Ti] Título:Safe and sustainable: the extracranial approach toward frontoethmoidal meningoencephalocele repair.

[Ab] Resumo:OBJECTIVE Although rare, frontoethmoidal meningoencephaloceles continue to pose a challenge to neurosurgeons and plastic reconstructive surgeons. Especially when faced with limited infrastructure and resources, establishing reliable and safe surgical techniques is of paramount importance. The authors present a case series in order to evaluate a previously proposed concise approach for meningoencephalocele repair, with a focus on sustainability of internationally driven surgical efforts. METHODS Between 2001 and 2016, a total of 246 patients with frontoethmoidal meningoencephaloceles were treated using a 1-stage extracranial approach by a single surgeon in the Department of Neurosurgery of the Yangon General Hospital in Yangon, Myanmar, initially assisted by European surgeons. Outcomes and complications were evaluated. RESULTS A total of 246 patients (138 male and 108 female) were treated. Their ages ranged from 75 days to 32 years (median 8 years). The duration of follow-up ranged between 4 weeks and 16 years (median 4 months). Eighteen patients (7.3%) showed signs of increased intracranial pressure postoperatively, and early CSF rhinorrhea was observed in 27 patients (11%), with 5 (2%) of them requiring operative dural repair. In 8 patients, a decompressive lumbar puncture was performed. There were 8 postoperative deaths (3.3%) due to meningitis. In 15 patients (6.1%), recurrent herniation of brain tissue was observed; this herniation led to blindness in 1 case. The remaining patients all showed good to very good aesthetic and functional results. CONCLUSIONS A minimally invasive, purely extracranial approach to frontoethmoidal meningoencephalocele repair may serve well, especially in middle- and low-income countries. This case series points out how the frequently critiqued lack of sustainability in the field of humanitarian surgical missions, as well as the often-cited missing aftercare and dependence on foreign supporters, can be circumvented by meticulous training of local surgeons.

[Ab] Resumo:BACKGROUND: Frontotemporal craniotomies are the most commonly performed neurosurgical approaches. We studied the external bony landmarks on the lateral surface of the skull to identify a "strategic" point where both the anterior and middle cranial fossae are exposed simultaneously during frontotemporal craniotomies through a single burr hole placed over the greater wing of the sphenoid bone (sphenopterional point). OBJECTIVE: This study aimed to anatomically define the sphenopterional point via craniometric measurements taken on the lateral surface of the human skull. METHODS: This study used 100 adult (age >18 years old) human dry crania (200 sides) with the calvaria removed, which were cataloged by gender and age. By using laser transillumination, the sphenopterional point was accurately identified in the temporal fossa. Measurements were taken using easily identifiable bony landmarks. On the basis of these landmarks, the horizontal and vertical distances were established between the sphenopterional point and the frontozygomatic suture. RESULTS: Regardless of gender or the side of the skull, the mean horizontal distance was 21.72 mm (SD, 3.17 mm; range, 14.25 mm-32.58 mm), and the mean vertical distance was 4.76 mm (SD, 1.74 mm; range, 0.00-9.73 mm). Neither the horizontal (right side, P = 0.621; left side, P = 0.341) nor the vertical measurements (right side, P = 0.460; left side, P = 0.609) differed significantly between genders. Therefore males and females present, on average, the same vertical and horizontal measurements on both sides. CONCLUSIONS: According to our measurements, the sphenopterional point is located, on average, 21.72 mm posterior and 4.76 mm superior from the frontozygomatic suture, over the sphenoidal bone component of the pterion region.

[Ab] Resumo:BACKGROUND: Despite advances in endoscopic sinus surgery, frontal sinus obliteration is still indicated in some cases. Current options for obliteration include autologous and synthetic materials. The use of ß-tricalcium phosphate as a resorbable bone graft substitute is a good alternative for frontal sinus obliteration. This study aimed to report our experience with this material. METHODS: A retrospective chart review of patients who underwent frontal sinus obliteration at our clinic between 2008 and 2013 was performed. Demographic data, indications, previous surgery, and immediate and late complications were examined. Information on persisting symptoms and patient outcomes was collected using a telephone questionnaire in February 2016. RESULTS: None of the patients underwent further surgery for frontal sinus disease. All of them reported a good cosmetic result and symptom improvement. CONCLUSION: ß-tricalcium phosphate is a good, safe and cost-effective material for frontal sinus obliteration.

[Ti] Título:Frontal Sinus Volume and Frontal Bar Position Are Associated in Unicoronal Craniosynostosis.

[Ab] Resumo:BACKGROUND: Frontal sinus pneumatization plays an important role in brow protrusion, and absence of frontal sinus development may be associated with brow retrusion. Using unicoronal craniosynostosis as a model, the authors studied the relationship among frontal sinus volume, supraorbital retrusion, and brow position. METHODS: The authors conducted a retrospective review of unicoronal craniosynostosis patients with head computed tomographic scans and photographs taken from ages 5 to 18 years. Frontal sinus volume and supraorbital retrusion were calculated using three-dimensional computed tomographic reconstructions. A "brow score" from 0 to 3 was assigned to each patient's photographs by a consensus of two craniofacial surgeons; sinus morphology and brow scores were compared. RESULTS: The study included 20 unicoronal craniosynostosis patients. The affected side demonstrated increased retrusion (7.1 ± 3.7 mm versus 3.0 ± 3.1 mm; p < 0.001) and decreased frontal sinus volume (0.8 ± 0.9 cc versus 2.6 ± 1.8 cc; p < 0.001). Qualitative brow retrusion scores differed between affected and unaffected sides (score of 0, 17 percent affected versus 78 percent unaffected; score of 1, 28 percent versus 22 percent; score of 2, 39 percent versus 0 percent; and score of 3, 17 percent versus 0 percent; p < 0.001). Brow scores trended with retrusion measurements (score of 0, 2.7 ± 2.9 mm retrusion; score of 1, 6.1 ± 3.5 mm; score of 2, 8.9 ± 3.2 mm; and score of 3, 9.7 ± 2.8 mm; p < 0.001). Subjects with brow scores of 0 or 1 had larger frontal sinus volumes than subjects with brow scores of 2 or 3 (p = 0.018). CONCLUSIONS: Qualitative brow retrusion correlates strongly with both quantitative supraorbital retrusion and frontal sinus volume. Although this retrospective study cannot prove causality, which is likely multifactorial, its strong correlation with frontal sinus pneumatization highlights the importance of the frontal sinus in brow position in unicoronal craniosynostosis. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

[La] Idioma:eng
[Ab] Resumo:BACKGROUND: Frontoethmoidal encephalocele is a congenital abnormality of the anterior skull base involving herniation of cranial contents through a midline skull defect. Patency of the foramen cecum, along with other multifactorial variables, contributes to the development of frontoethmoidal encephaloceles. Because of limited resources, financial constraints, and lack of surgical expertise, repair of frontoethmoidal encephaloceles is limited in developing countries. METHODS: Between 2008 and 2013 an interdisciplinary team composed of neurosurgeons, craniofacial surgeons, otolaryngologists, plastic surgeons, and nursing personnel, conducted surgical mission trips to Davao City in Mindanao, Philippines. All patients underwent a combined extracranial/intracranial surgical approach, performed in tandem by a neurosurgeon and a craniofacial surgeon, to detach and remove the encephalocele. This procedure was followed by reconstruction of the craniofacial defects. RESULTS: A total of 30 cases of frontoethmoidal encephalocele were repaired between 2008 and 2013 (20 male; 10 female). The average age at operation was 8.7 years, with 7 patients older than 17 years. Of the 3 subtypes, the following breakdown was observed in patients: 18 nasoethmoidal; 9 nasofrontal; and 3 naso-orbital. Several patients showed concurrent including enlarged ventricles, arachnoid cysts (both unilateral and bilateral), and gliotic changes, as well as orbit and bulbus oculi (globe) deformities. There were no operative-associated mortalities or neurologic deficits, infections, or hydrocephalus on follow-up during subsequent trips. CONCLUSIONS: Despite the limitations of performing advanced surgery in a developing country, the combined interdisciplinary surgical approach has offered effective treatment to improve physical appearance and psychological well-being in afflicted patients.

[Ab] Resumo:OBJECTIVE: Craniopharyngiomas are challenging tumors to resect due to their deep location and proximity to vital structures. The perceived benefit of gross total resection may be tempered by the possibility of permanent disability. Minimally invasive techniques may reduce surgical morbidity while still allowing effective resection. The authors describe their initial experience with a neuroendoscopic transcortical, transventricular approach to two craniopharyngiomas. The surgeries were performed through a right frontal burr hole using the NICO Myriad, a side-cutting, aspiration device that fits through the working channel of a standard neuroendoscope. METHODS: The imaging and medical records of two children (a 5-year-old male and a 9-year-old female) undergoing endoscopic resection of a craniopharyngioma with this technique were reviewed. Outcomes, results, and complications were noted. RESULTS: A gross total resection was achieved in both patients. The operative time was 180 and 143 min, respectively. The estimated blood loss was 20 and 50 cm , respectively. Both patients required a cerebrospinal fluid shunt. There were no surgical complications. CONCLUSIONS: The NICO Myriad is an effective tool that allows a safe minimally invasive endoscopic resection of craniopharyngiomas in patients with amenable anatomy. Surgeons with experience in neuroendoscopy may be able to achieve a gross total resection of these challenging tumors through a minimally invasive burr hole approach.

[Ab] Resumo:OBJECTIVES: The aim of this study was to determine the influence of different frontal bone defect localizations on primary stability values of 2 different implant designs. MATERIALS AND METHODS: Eight cow rib segments were prepared before implant installation, as 2 segments with coronal, 2 with middle, and 2 with apical defects and 2 with control. Thirty-two cylindrical and 32 tapered implants were placed in the remaining 4 segments. Implant stability measurements were performed using electronic percussive testing and resonance frequency analysis. RESULTS: No significance was detected between the stability values of the 2 implant designs except the implant stability quotient (ISQ) of control groups. The tapered implants control group showed significantly higher lateral ISQs compared with cylindrical implants (P = 0.033). For both implant types, stability values were significantly lower in coronal defects (P < 0.01). No significant differences were detected in other defect types. CONCLUSION: Within the limitations of this study, it may be concluded that coronal defects may influence primary stability negatively, compared with middle and apical defects. Although statistically not significant, coronal defects caused lower primary stability values with the tapered design compared with parallel design.
