1. Bone wax migrates to the orbit in a patient with a frontal sinus abnormality: a case report. (PubMed)

Bone wax migrates to the orbit in a patient with a frontal sinus abnormality: a case report. Bone wax is the most widely used hemostatic bone sealant because of its availability, ease of use, immediate action, and minimal adverse effects. Several complications have been reported to be associated with the use of bone wax, such as infection, osteohypertrophy, pain, granuloma formation, allergic reaction, and thrombosis. Here, we present a rare complication, namely, bone wax migration, which (...) developed after a craniotomy on a patient who had a frontal sinus abnormality.A 51-year-old woman complained of pain and swelling in her left eye accompanied by difficulty opening the left eyelid after undergoing a craniotomy. An examination revealed left eye proptosis with ptosis, eyelid swelling, and increases in intraorbital pressure and intraocular pressure (IOP). According to a CT and an MRI of the orbit, we found that the intraoperative bone wax had migrated to the orbit, thereby causing

2. Feminizing the Face: Combination of Frontal Bone Reduction and Reduction Rhinoplasty (PubMed)

Feminizing the Face: Combination of Frontal Bone Reduction and Reduction Rhinoplasty Gender affirmation surgeries in male-to-female patient transitioning include breast augmentation, genital construction, and facial feminization surgery (FFS). FFS improves mental health and quality of life in transgender patients. The nose and forehead are critical in facial attractiveness and gender identity; thus, frontal brow reduction and rhinoplasty are a mainstay of FFS. The open approach to reduction (...) of the frontal brow is very successful in the feminization of the face; however, risks include alopecia and scarring. Endoscopic brow reduction, in properly selected patients, is minimally invasive with excellent outcomes avoiding these risks. Since both reduction rhinoplasty and frontal brow reduction are routinely performed in FFS, a combined approach provides superior control over the nasal radix and profile when performing surgery on the frontal bone region first followed by nose reduction.

3. Role of the Frontal Sinus in Mediating Ocular Vestibular-Evoked Myogenic Potentials by Bone Vibration Stimuli Applied to the Forehead. (PubMed)

Role of the Frontal Sinus in Mediating Ocular Vestibular-Evoked Myogenic Potentials by Bone Vibration Stimuli Applied to the Forehead. This study investigated ocular vestibular-evoked myogenic potential (oVEMP) tests via Fpz and Fz taps to assess the role of the frontal sinus in mediating oVEMP elicitation. Forty healthy subjects and 80 patients with Ménière disease (MD) underwent a series of oVEMP tests via a minishaker tapping at the Fpz and Fz sites in a randomized order. Response rates (...) ) than females (3.42 ± 0.67 cm). In conclusion, the height of the frontal sinus plays a role in mediating the elicitation of oVEMPs. The oVEMPs could be easily elicited by the first-order bone vibration (Fpz/Fz tapping) coupled with the second-order resonance effect (with a high extent of the frontal sinus). Thus, initial tapping at the Fpz site is suggested. If it fails, try the Fz site for screening the oVEMPs.© 2018 S. Karger AG, Basel.

4. Osteoblastoma of the frontal bone invading the orbital roof: A case report. (PubMed)

Osteoblastoma of the frontal bone invading the orbital roof: A case report. Osteoblastoma is an uncommon primary bone tumor that involves any part of the skeleton. But its occurrence in the skull is extremely rare.A 30-year-old female was admitted to our hospital, because of the mass in the right frontal region with the history of headache for 3 years without nausea or vomiting.Initial differential diagnoses included hemangiopericytoma, atypical intraosseous meningioma, calvarial osteosarcoma (...) , fibrous dysplasia, and histiocytosis, based on the results of enhanced CT and MRI.A total surgical resection of the mass was performed.Postoperative histopathologic analysis demonstrated the typical features of osteoblastoma, the benign bone neoplasm. Serial radiologic examination did not show recurrence in the 6 months follow-up.The radiologic appearance of the osteoblastoma is always confusing and makes the diagnosis difficult. We hope our case can give some clinical clues for the diagnosis

7. Giant Cell Tumor of the Frontal Bone: A Case Report and Literature Review (PubMed)

Giant Cell Tumor of the Frontal Bone: A Case Report and Literature Review Giant cell tumors are rare benign lesions that typically occur at the epiphyses of long bones in the extremities and present with pain or swelling. These lesions very seldom occur in the skull, where they preferentially affect the sphenoid and temporal bones that develop by endochondral ossification. We report a rare case of a giant cell tumor of the frontal bone and review the literature on these lesions. A 21-year-old (...) woman presented with localized swelling and tenderness over the left frontal bone. Imaging revealed a lytic lesion involving the left frontal bone, which was managed via left frontal craniectomy with resection of the bone and epidural mass. Histopathology revealed a giant cell tumor of bone (GCTB). Most data on giant cell tumors in the skull consist of case reports, with many large series of giant cell tumors having no examples in the skull. This report contributes to the scarce literature

8. Primary osteosarcoma of frontal bone: A case report and review of literature. (PubMed)

Primary osteosarcoma of frontal bone: A case report and review of literature. 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.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.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.The patient received 3 surgeries and adjuvant chemotherapy and radiotherapy for the frontal bone lesion.At the last follow-up, after 4 years, the patient was free of disease both clinically and on imaging by magnetic resonance

9. First results of frontal sinus obliteration with a synthetic, resorbable and osteoconductive bone graft of ß-tricalcium phosphate. (PubMed)

First results of frontal sinus obliteration with a synthetic, resorbable and osteoconductive bone graft of ß-tricalcium phosphate. 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.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.None of the patients underwent further surgery for frontal sinus disease. All of them reported a good cosmetic result and symptom improvement.ß

10. Post-Traumatic Peripheral Giant Osteoma in the Frontal Bone (PubMed)

Post-Traumatic Peripheral Giant Osteoma in the Frontal Bone Osteomas are benign, slow-growing tumors that most frequently occur in the craniomaxillofacial region. These tumors are mostly asymptomatic and are generally found incidentally. A giant osteoma is generally considered to be greater than 30 mm in diameter or 110 g in weight. A 35-year-old female presented to us with complaints of a firm mass that showed continuous growth on the forehead following trauma. A hairline incision was made (...) to expose the osteoma. Biopsy of the tumor confirmed a osteoma. There were no complications after surgery. Postoperative computed tomography revealed that the tumor was completely removed. Because a peripheral giant osteoma of the frontal bone with a history of trauma is a rare finding, thorough history-taking, physical examination, and preoperative imaging tests are needed for patients with a history of trauma to rule out a giant osteoma.

Why a Catheter Can Be Correctly Placed in the Anterior Horn of Lateral Ventricle by Inserting Perpendicular to the Frontal Bone on the Ventricular Drainage? Demonstration of the Accuracy of an Inserting Path by Computed Tomographic Image Study and Clinica Why a catheter can be correctly placed in the ventricle by inserting perpendicular to the frontal bone on the ventricular drainage? We performed a study on the accuracy of a path perpendicular to the skull surface into the anterior horn using (...) hydrocephalic patients (158 surgeries). We discovered that the curved surface of the frontal bone around Kocher's point represents the surface of a globe (mean radius, 75.9 ± 4.3 mm) centering on the foramen of Monro. The distribution of points ranged from 13.5-43.5 mm (mean, 43.5 ± 6.1 mm) to the midline, with points appearing more laterally as ventricular size increased. A catheter was placed in the ventricle in 148 surgeries (99.4%), and the catheter reached the ventricle with correct orientation toward

Mice lacking the conserved transcription factor Grainyhead-like 3 (Grhl3) display increased apposition of the frontal and parietal bones during embryonic development Increased apposition of the frontal and parietal bones of the skull during embryogenesis may be a risk factor for the subsequent development of premature skull fusion, or craniosynostosis. Human craniosynostosis is a prevalent, and often serious embryological and neonatal pathology. Other than known mutations in a small number (...) morphology and size in adult animals lacking one Grhl3 allele (heterozygous; Grhl3 +/- ), which are viable and fertile. We found that these adult mice also present with a smaller cranial cavity, suggestive of post-natal haploinsufficiency in the context of cranial development.Our findings show that our Grhl3 mice present with increased apposition of the frontal and parietal bones, suggesting that Grhl3 may be involved in the developmental pathogenesis of craniosynostosis.

18. Novel use of an ultrasonic bone aspirator for extended endoscopic frontal sinusotomy: A feasibility study. (PubMed)

Novel use of an ultrasonic bone aspirator for extended endoscopic frontal sinusotomy: A feasibility study. Extended endoscopic frontal sinusotomy is often required for surgical management of anterior skull base pathology. Such approaches are necessary for access to pathology and maintenance of postoperative frontal sinus outflow tract drainage. Cold steel instrumentation and endoscopic high-speed microdrills are typically used for bony removal during extended frontal sinus approaches (...) but are associated with certain drawbacks, such as thermal injury and obscuration of the surgical field with bone dust.We investigated the ultrasonic bone aspirator (UBA) as an adjunctive tool for extended endoscopic frontal sinusotomy in the setting of skull base surgery.Medical records of patients who underwent either Draf IIB or Draf III sinusotomies from 2011 to 2014 were reviewed. The patients were split into two cohorts based on instrumentation: those who received sinusotomy primarily with the UBA

19. Frontal Bone Insufficiency in Gsk3β Mutant Mice (PubMed)

Frontal Bone Insufficiency in Gsk3β Mutant Mice The development of the mammalian skull is a complex process that requires multiple tissue interactions and a balance of growth and differentiation. Disrupting this balance can lead to changes in the shape and size of skull bones, which can have serious clinical implications. For example, insufficient ossification of the bony elements leads to enlarged anterior fontanelles and reduced mechanical protection of the brain. In this report, we find (...) that loss of Gsk3β leads to a fully penetrant reduction of frontal bone size and subsequent enlarged frontal fontanelle. In the absence of Gsk3β the frontal bone primordium undergoes increased cell death and reduced proliferation with a concomitant increase in Fgfr2-IIIc and Twist1 expression. This leads to a smaller condensation and premature differentiation. This phenotype appears to be Wnt-independent and is not rescued by decreasing the genetic dose of β-catenin/Ctnnb1.
