Fully Endoscopic Resection of Frontal Osteomas.

BACKGROUND: Osteomas are the most common primary bone tumors of the calvaria, with an incidence of less than 0.5%. In skull vault osteomas, the exostotic form that grows from the outer table is more common than the enostotic ones which arise from the inner table and grow intracranially. Osteomas of the forehead are very noticeable and disfiguring; patients usually seek medical advice for cosmetic reasons. Forehead osteomas were traditionally excised via either a direct incision over the lesion using the naturally occurring creases or a conventional bicoronal flap. More recently, endoscopic approaches for excision of forehead osteomas were introduced. The results were very encouraging and the technique was adopted by many groups worldwide yet with many technical variations. In this chapter we elaborate on the surgical technique and nuances of the fully endoscopic resection of frontal osteomas. METHODS: From a prospective database of endoscopic procedures maintained by the senior author, clinical data, imaging studies, operative charts, and videos of cases of forehead osteomas were retrieved and analyzed. The pertinent literature was also reviewed. RESULTS: The surgical technique of the fully endoscopic resection of frontal osteomas was formulated. CONCLUSION: The endoscopic technique has many advantages over the conventional procedures. In our hands, the technique has proven to be less time-consuming, efficient, and minimally invasive with excellent cosmetic results.

A Case Report of Craniofacial Intraosseous Xanthoma in a Patient Seeking Facial Feminization Surgery.

BACKGROUND: Fibrous dysplasia (FD) is a benign developmental disorder of the bone that causes normal skeletal tissue to be replaced by excess fibrous tissue and poorly differentiated osteoblasts. Intraosseous xanthomas are benign intraosseous tumor growths characterized microscopically by the presence of lipid-laden foamy histiocytes, often with cortical expansion or disruption. Although FD commonly occurs in craniofacial bones, primary intraosseous xanthomas of the skull or facial skeleton are extremely rare. Although 2 distinct conditions, each may be difficult to differentiate on CT imaging when occurring in the facial skeleton. METHODS: We report a case of an incidental finding on craniofacial CT of a frontal bone lesion originally thought to be FD. The finding was in a 55-year-old transgender woman who was assigned male at birth before receiving multiprocedural facial feminization surgery. RESULTS: The clinical features, radiological findings, and treatment are discussed. Postoperatively, the patient had no sequelae secondary to facial feminization surgery or to the orbital lesion biopsy procedure. Bone graft appeared stable on CT imaging, although FD did not appear to resolve completely. CONCLUSIONS: Diagnosis of such lesions is challenging and may require both radiographic and histopathologic assessment. As in the case of this patient, intraosseous xanthomas may also be misdiagnosed as other benign lesions such as FD. In most known cases, surgical intervention leads to complete resolution without recurrence of the lesion.

1-Piece Versus 2-Piece Fronto-Temporo-Orbito-Zygomatic Craniotomy: A Narrative Overview of Evolution.

BACKGROUND: The fronto-temporo-orbito-zygomatic (FTOZ) craniotomy is a commonly utilized surgical approach for many complex skull base lesions, especially lesions traversing skull base compartments. This craniotomy has evolved over multiple stages, originating from the classic pterional craniotomy and many variations that have emerged over time. METHODS: Few clinical and anatomic studies have both shaped these craniotomies as well as provided immense information about instances in which they are most useful. We review the origin and history of the one-piece and two-piece fronto-temporo-orbito-zygomatic craniotomy and deliberate their advantages and disadvantages. RESULTS: The FTOZ craniotomy provides access to the orbit as well as to multiple compartments in the cranium (anterior, middle and upper third posterior cranial fossae); thus, offering a multi-corridor approach to complex skull base lesions. The one-piece and two-piece fronto-temporo-orbitozygomatic craniotomies are two particularly notable variations that have stood the test of time. Selection between the two variations is mostly surgeon preference and comfort with the technique; however, there are certain indications that specifically suit each approach. Additionally, a pictorial review has been crafted to clearly illustrate the cuts to be made in both methods. CONCLUSION: Understanding the evolution of this craniotomy and surgical approach provides an insight into accessing complex skull base pathologies with minimal brain retraction via safe and viable corridors.

Are the Ethmoidal Foramina Through the Frontal Bone, Ethmoid Bone, or Frontoethmoidal Suture?

INTRODUCTION: To investigate the locations of the anterior, middle, and posterior ethmoidal foramina and their relationships to the frontoethmoidal suture. METHODS: One hundred twenty sides from sixty adult human skulls were used. Specimens with significant damage to the medial orbit wall were excluded. The number of ethmoidal foramina (anterior, middle, and posterior) on the medial orbital wall and the relationship of each foramen to the frontoethmoidal suture were recorded and classified as follows: Type I: superior to the frontoethmoidal suture; Type II: on the frontoethmoidal suture; Type III: inferior to the frontoethmoidal suture. RESULTS: Of the ninety-four sides, fourteen (14.9%) had one foramen, sixty-two (66.0%) had two , and eighteen (19.1%) had three. In total, 192 ethmoidal foramina were observed. Among the fourteen sides with one foramen, eight foramina were anterior and six were posterior. Among the 192 ethmoidal foramina, 162 were eligible for fur ther classification (74 anterior, 14 middle, and 74 posterior). Types I, II, and III ethmoidal foramina were found in 38.3% (62/162), 61.7% (100/162), and 0% (0/162), respectively. CONCLUSIONS: Our current study found a higher incidence of type I than previously reported. It is important to be aware of the significant incidence of foramen variations when the medial orbit wall is manipulated during surgery. Unless caution is observed, an inadvertent surgical injury can occur and lead to life-threatening complications. Therefore, a good understanding of orbital anatomy and its potential variations is critical for improving patient out comes.

Surgical Treatment of Trigonocephaly, Simplified Technique for Moderate Cases.

BACKGROUND: The prevalence of trigonocephaly has increased worldwide over the past 2 decades. Early identification and appropriate treatment are critical. The aim of this study is to evaluate the outcomes and the effect of metopic suture excision, perisutural frontal bone shave, and bilateral pericranial flap method on the shape of the forehead after surgical correction in infants with moderate trigonocephaly. METHODS: The present study was performed as a cross-sectional study on 40 infants of 3 to 12 months old with trigonocephalus who underwent metopic suture excision and pericardial flap surgery in Mofid Pediatric Hospital from 2016 to 2022. The definitive diagnosis of patients' trigonocephaly was made based on clinical signs and computed tomography scan findings by a plastic surgeon. RESULTS: Overall in 40 patients operated by this technique, 23 (57.5%) of cases were males, and 17 (42.5%) were females. The mean age of patients was 7.86 ± 2.22 months. Hospital stay was 2 to 4 days (mean: 3 d), intensive care unit admission was in 33 cases for 24 hours, and no intensive care unit admission for 7 cases. Blood was transfused during surgery for 25 patients, and 15 patients did not require blood transfusion use. Results were evaluated in 6 to 12 months after surgery by 3 independent plastic surgeons, with pre and postoperative photos. Satisfaction with the results of forehead shape was excellent for 60% of patients, good for 37.5%, and moderate for 2.5%. Only one female patient had a recurrence after the surgery. CONCLUSION: This study showed that the pericranial flap method after full metopic suture excision and frontal shave was very effective in the treatment of infants with moderate trigonocephaly.

Management of Total Frontal Bone Loss After Surgery for Craniosynostosis: The Modified Visor Bone Flap With Brain Cage.

Complications after craniosynostosis surgery occur in 11% to 36% of cases and may be precipitated by poor soft tissue coverage and concomitant exposure of non-sterile regions; sequelae may result in infection, osteomyelitis, and bone loss requiring complex reconstruction. In the pediatric population, autologous cranioplasty remains the gold standard due to growth potential and a more favorable complication profile than synthetic cranioplasty. Virtual surgery planning (VSP) and computer-assisted design (CAD)/computer-assisted manufacturing (CAM) technology can be utilized to create innovative, patient-specific autologous solutions, similar to the approach with synthetic cranioplasty. A novel surgical approach using VSP was used for an 18-month-old female with near total bifrontal bone loss. Surface area measurements were used to determine the amount of bone available to replace the infected frontal bone. VSP was utilized to determine the most efficient construct configuration possible to achieve maximal coverage via calculation of cranial bone surface area measurements. Surgical reconstruction of the defect was planned as a Modified Visor Bone Flap with Posterior Brain Cage. A construct was fashioned from available cranial bone struts to obtain widespread coverage. 3D Recon images from before and after surgery demonstrate almost complete re-ossification of the cranial vault with significant resulting clinical improvement. Reconstruction of total frontal bone loss is possible by utilizing this technique. VSP can improve the safety and efficiency of complex autologous cranial bone reconstructions. We propose a treatment algorithm to address the problem of near total frontal bone loss in young children for whom alloplastic implants are not suitable.

Frontal Osteomyelitis and Sinusitis Complication After Type III Frontal Bone Cranioplasty for Facial Feminization.

Background: Forehead contouring can be a component of facial feminization surgery (FFS). Its complications have been rarely reported on and are often described as "hypothetical." Methods: A case report of complications from forehead contouring resulting in frontal osteomyelitis and sinusitis. Results: A female patient presented with frontal osteomyelitis, sinusitis, and forehead contour deformity after a type III forehead contouring surgery. She had failed prior treatment including oral antibiotics, IV antibiotics, revision sinus surgery, and revision nasal surgery. For definitive treatment, she underwent an anterior table resection, sinus obliteration with bony contouring, and pericranial flap. Conclusions: Forehead contouring represents a recent significant advancement in FFS and gender-affirming therapy. Descriptions of complications and their management are important when novel therapies such as FFS are introduced. This case demonstrates complications from type III forehead contouring including osteomyelitis, frontal sinusitis, and forehead deformity.

Commentary on: "Frontal Osteomyelitis and Sinusitis Complication After Type III Frontal Bone Cranioplasty for Facial Feminization" by Brown et al.

We present a complementary report of a 38-year-old XY intersex female with frontal mucopyocele developing 5 years after frontal setback for gender-affirming surgery to supplement recent report by Brown et al: Frontal Osteomyelitis and Sinusitis Complication After Type III Frontal Bone Cranioplasty for Facial Feminization by Brown et al.

Secondary aneurysmal bone cyst of the frontal bone with fibrous dysplasia showing rapid expansion: a case report.

A 19-year-old woman presented with swelling of the left forehead without pain. She did not have any relevant past or family history. Computed tomography showed destruction of the outer cortex of the frontal bone. A solitary mass lesion with a fluid collection was detected with magnetic resonance imaging. Because the swelling of the left forehead had enlarged rapidly with osteolytic changes, surgical removal of the lesion was performed. The lesion appeared to be enveloped in a fibrous capsule. The soft lesion was removed from the frontal bone. The outer frontal bone was absent, although the inner frontal bone was preserved. Then, the frontal bone was resected with margins from the edge of the erosion. The dura mater under the lesion was intact. A cranioplasty was performed using titanium mesh. On histological examination, the trabecular bones revealed irregular shapes and arrangements, indicating fibrous dysplasia. There was a continuous high-cell-concentration pathological lesion outside the fibrous dysplasia. There were numerous cells, such as mononuclear cells, osteoclast-like multinucleated giant cells, foam cells, and red blood cells. The osteoclast-like multinucleated giant cells and other cells did not show significant nuclear atypia. Immunostaining with H3.3G34W was negative, and the ubiquitin-specific peptidase 6/Tre-2 gene showed no rearrangements. The histopathological diagnosis was secondary aneurysmal bone cyst with fibrous dysplasia. Additional postsurgical therapy was not performed. There has been no evidence of recurrence of the lesion for two years.

Growing skull fracture in a child with Ehlers-Danlos syndrome: case report and literature review.

INTRODUCTION: Growing skull fracture (GSF) is a rare complication of head trauma in the pediatric population, commonly observed in children younger than 3 years. DISCUSSION: In this report, the authors describe a case of a 3-year-old male child, with clinical features of Ehlers-Danlos syndrome (EDS), who developed a GSF in frontal bone after a crib fall, treated with duraplasty and cranioplasty with autologous craft. Here, pertinent literature was reviewed with an emphasis on surgical techniques, and correlation with the mentioned syndrome. CONCLUSION: This is the first case of GSF in association with EDS in the literature. The relevance of the case described concerns the rarity of the condition itself, the atypical presentation, and the intraoperative findings, which showed the important fragility of the dura mater, probably due to EDS. Therefore, this syndrome, besides having influenced the pathogenesis, was also a challenging factor in the surgical treatment.

Prognosis of Performing Split-Rib Bone Graft for Cranial Bone Defects.

BACKGROUND: Frontal sinus anterior wall defects occur because of various diseases, causing not only aesthetic problems, such as forehead bulging and upper eyelid ptosis, but also exerting physical pressure on the brain or optic nerve. Therefore, this study aimed to evaluate the prognosis of performing split-rib bone graft for frontal sinus anterior wall defects. METHODS: This study included 30 patients who received a split-rib bone graft for a frontal sinus anterior wall defect. The sizes and volumes of the defects and grafts were measured using three-dimensional computed tomography before, after, and every 6 months for 2 years after the surgery. The Medical Imaging Interaction Toolkit was used for analysis. RESULTS: The average size and volume of the grafts were 27.29 cm 2 and 5.88 cm 3 , whereas they were 23.76 cm 2 and 4.80 cm 3 at 24 months after surgery, respectively. In a graft size and volume of less than 27 cm 2 and 6 cm 3 , respectively, the rate of graft take was greater than 80% during long-term observation. The younger the age, the higher the rate of graft take. No difference was found in the defect causes. Absorption occurred for up to 18 months. CONCLUSIONS: Frontal bone defect reconstruction revealed the stable results of the split-rib bone graft over a long period when the size and volume were less than 27 cm 2 and 6 cm 3 , respectively. Furthermore, bone resorption was seen in more than 20% to 30% of the patients, and the rate of resorption increased with age; thus, it is appropriate to consider overcorrection and other reconstruction methods. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Intraosseous malignant peripheral nerve sheath tumor at the frontal bone in a child: a rare cause of proptosis.

We report a nine-year-old male having malignant peripheral nerve sheath tumor (MPNST) of the frontal bone, represented with a twelve-month history of ptosis and proptosis in his right eye and enlarged rapidly in the last three months. Except for slight numbness at his one-third of the right forehead, he had no neurological deficit. The patient's both eyes were having normal eye movements, and he had no visual acuity or field loss. After surgery, we observed the patient with no recurrence for 4 years.

Endoscopic Approach for Resection of Frontal Forehead Osteoma: Technical Case Report Instruction.

Forehead osteomas are benign bone tumors. They are frequently associated with exophytic growth in the outer table of the skull, causing cosmetic disfigurement of the face.1-9 The objective of this study was to present the efficacy and feasibility of the endoscopic treatment of forehead osteomas by presenting a case report with details of the surgical technique. A 40-year-old female patient presented with aesthetic complains of a progressing bulge in the forehead. A computed tomography scan with 3-dimensional reconstruction showed bone lesions on the right side of the forehead. The patient underwent surgery under general anesthesia with no noticeable incision, which was planned 2 cm behind the hairline in the midline because the osteoma was close to the midline plane on the forehead (Video 1). A retractor coupled with a 4-mm channel for endoscopy and a 30-degree optic was used to dissect, elevate the pericranium, and locate the 2 bone lesions in the forehead. The lesions were removed using a chisel, endoscopic facelifting raspatory, and a 3-mm burr drill. The tumors were resected completely, resulting in good cosmetic outcomes. The endoscopic approach for treating forehead osteomas is less invasive and facilitates complete removal of tumors, which results in good cosmetic outcomes. Neurosurgeons should consider and add this feasible approach to enhance their surgical armamentarium.

Orbital Schwannoma With Frontal Bone Lysis.

Orbital schwannoma is an exceptionally rare cause of ptosis. Diagnosis may be elusive given its slow rate of growth and its various presentations depending on localization. Herein, we report the case of a 50-year-old male who presented to our clinic with a complaint of unilateral, recurrent ptosis of the left eye. He underwent levator palpebrae resection, which was unsuccessful at improving his ptosis. He later represented with acute-onset diplopia for which magnetic resonance imaging was obtained. Magnetic resonance imaging showed a lesion in the superior orbit with secondary bony dehiscence of the orbital roof. Through a vertical lid-split incision, the lesion was removed, and the frontal lobe was observed protruding through the defect in the orbital roof. This case highlights the importance of diagnostic skepticism in the face of recurrent ptosis and emphasizes the utility of the vertical lid-split approach for anterior lesions of the superior orbit.

Long-term aesthetic and photogrammetric outcomes in non-syndromic unicoronal synostosis: comparison of fronto-orbital distraction osteogenesis and fronto-orbital advancement and remodeling.

BACKGROUND: Fronto-orbital advancement and remodeling (FOAR) is among the most common surgical approaches for unicoronal craniosynostosis (UCS), although some data demonstrate failure to achieve long-term aesthetic normalcy, leading some to seek alternative treatment paradigms such as fronto-orbital distraction osteogenesis (FODO). This study compares long-term aesthetic outcomes of patients with UCS treated with FOAR and FODO. METHODS: Twenty patients (four males) with non-syndromic UCS presenting to our institution and undergoing distraction were compared to a matched cohort of 20 patients (six males) undergoing FOAR. Clinical photographs and ImageJ were used to quantify periorbital anatomy including palpebral fissures, pupil-to-brow distance (PTB), and margin-reflex distance (MRD1) in pixels. Whitaker classification was blindly assigned by craniofacial surgeons. RESULTS: Photogrammetric analysis and Mann-Whitney U tests demonstrated significantly improved postoperative symmetry in distraction patients for palpebral width (p = 0.020), MRD1 (p = 0.045), and canthal tilt (p = 0.010). Average Whitaker classification scores between FOAR (1.94) and distraction (1.79) cohorts were similar (p = 0.374). CONCLUSIONS: UCS patients demonstrated significant postoperative improvements in periorbital symmetry, with distraction patients demonstrating superior results in palpebral width and canthal tilt. FOAR and FODO patients achieved similar Whitaker classification scores. These cohorts will be followed until craniofacial maturity prior to making any definitive conclusions.

Single-Stage Titanium Mesh Cranioplasty for the Treatment of Depressed Skull Fractures.

BACKGROUND: Historically, depressed skull fractures that warranted surgery were treated in 2 stages: the first stage involved debridement and craniectomy, followed by the second stage of delayed cranioplasty. More recently, single-stage autologous cranioplasty has been proven to be safe. However, there is a paucity of literature regarding single-stage titanium mesh cranioplasty when autologous repair is not possible. METHODS: A retrospective review identified 22 patients who underwent single-stage titanium mesh cranioplasty for the acute treatment of comminuted depressed skull fractures. Fracture location, fracture etiology, timing of surgery, neurologic complications, infection, and cosmetic deformity were recorded. Average follow-up was 9 months. RESULTS: The mean age of the patients was 34 years (range: 3-77); 83% were male. Seventeen (77%) involved the frontal bone, with 7 (32%) involving the frontal sinus. Eighteen (82%) had open defects at presentation. Sixteen (73%) were neurologically normal. Average time from presentation to repair was 11 hours (range: 1-28 hours). There were no neurologic worsening, seizures, or infections postoperatively. Antibiotic prophylaxis was prescribed in 13 cases (57%). One patient required revision surgery for persistent cosmetic deformity. CONCLUSIONS: Autologous cranioplasty for depressed skull fractures is not always possible especially in cases of significant comminution. From our case series, single-stage titanium mesh cranioplasty appears to be a safe option.

Neoforehead Remodelling Techniques for Fronto-Orbital Advancement and Remodelling in the Oxford Craniofacial Unit: Lateral Remodelling and a Novel Central Self-Stabilizing S-Osteotomy Technique.

Fronto-orbital advancement and remodelling (FOAR) has undergone many modifications over the years, aimed at improving outcomes and reducing risks for patients. This work describes 2 techniques for remodelling the neoforehead used by the Oxford Craniofacial Unit since 1995: lateral remodelling and a central S-Osteotomy. Both methods adopt bone from the vertex as a neoforehead, but they differ in their techniques to adapt its shape to that of the newly remodelled orbital bandeau. The novel S-Osteotomy technique can be successfully applied to all FOAR procedures, irrespective of underlying synostosis and calvarial symmetry. It was originally developed for when 2 separate bony panels were required to create a neoforehead in asymmetrical cases, but was adopted for single panel neoforehead designs in metopic synostosis with the idea it may reduce temporal hollowing. An investigation of temporal hollowing in these patients who underwent either of the described methods was undertaken to assess this hypothesis with no statistically significant difference seen ( P =0.1111). Both techniques on average resulted in minimal hollowing that was not felt to require any revision, supporting the belief that temporal hollowing is a multifactorial issue. This work describes 2 successful methods of neoforehead remodelling and introduces the S-Osteotomy technique that can be applied in all FOAR procedures.

Reconstruction of depressed skull fracture in school patients. Technique description.

OBJECTIVE: Depressed skull fractures are the result of trauma injuries. They are present in approximately 3% of patients who arrive to an emergency room with skull trauma. The main objective of surgical repair in depressed fractures is correction of cosmetic deformity and the prevention of infections. MATERIAL AND METHODS: A retrospective and transversal study was performed by our department between April 2016 and May 2017. Sixteen patients that underwent a craniotomy for skull trauma with depressed fracture were included in the study. The diagnosis was made by simple cranial CT scan alongside a three-dimensional reconstruction. RESULTS: Of the sixteen patients included, 5 were females (31.2%) and 11 males (68.8%). Twelve of the cases were an exposed fracture. In 7 cases, the fracture was located at parietal bone; 5 were located at frontal bone and 4 at the temporal bone. The average Glasgow coma score in the sample was 13. There were no complications nor deaths. CONCLUSIONS: The remodeling and repositioning of the autologous bone graft allow an adequate cosmetic result and it also avoids the placement of implants without increasing the costs and additional risks.

El puntaje promedio en la Escala de Coma de Glasgow fue 13. No hubo complicaciones o muertes. CONCLUSIONES: la remodelación y el reposicionamiento del injerto óseo autólogo permite un resultado cosmético adecuado evitando la colocación de implantes sin aumentar los costos y riesgos adicionales.

Morphometric Analysis of the Supraorbital Foramen and Notch in the Population of Bosnia and Herzegovina.

OBJECTIVE: The aim of this study was to learn about the morphological characteristics of the supraorbital foramen and to determine its precise position in relation to the surrounding anatomical landmarks in the adult population of Bosnia and Herzegovina. MATERIAL AND METHODS: For this purpose, 60 skulls from the Bosnia and Herzegovina population of known sex (32 males and 28 females), taken from the osteological collection of the Department of Human Anatomy of the Medical Faculty in Sarajevo, were subjected to morphological and morphometric analysis. Morphometric measurements were performed using a digital vernier caliper (Mitutoyo Corporation, Japan). RESULTS: The study showed that most supraorbital nerves exit the orbit through the supraorbital notch (73.8%) and the rest through the foramen (26.2%). Of this number, bilateral supraorbital notches were recorded in 58.33% of cases, a bilateral supraorbital foramen in 18.34% of cases, while in 23.33% of cases a notch was recorded on one side and a foramen on the contralateral side. Morphometric measurements performed to determine the exact position of the supraorbital foramen relative to the surrounding landmarks showed different values in males and females. An accessory foramen was also observed on the examined skulls in 16.67% of cases. CONCLUSION: Detailed knowledge of anatomical variations of the supraorbital foramen is required for safe and successful administration of regional anesthesia, in order to avoid iatrogenic nerve injuries during orbitofacial region surgery.

Frontal Bone Cranioplasty for Facial Feminization in Gender-Affirming Surgery: Can Fewer Screws Fixate Bone and Avoid Nonunion?

Background: Facial feminization surgery can include forehead feminizing cranioplasty (FFC). The reshaped bones are fixated together with titanium plates and screws. Objective: To define the authors' preferred plating patterns and measure complications of bony nonunion when less hardware is applied. Methods: A 7-year retrospective review of patients who underwent FFC was conducted. Data collection included cranioplasty technique, fixation patterns, and complications. Traditional fixation (≥2 screws on each side of the osteotomy) was compared with conservative fixation (<2 screws). Results: A total of 483 patients were identified with a median of 241 days of follow-up (interquartile range: 8-528 days). Most patients (77.8%) had frontal bone fixation with microplates and screws. The most common combination was placement of two plates with four screws in total, comprising two screws on each plate, with one screw on each side of the fracture line (305/483, 63.1%). No signs or symptoms of bone flap mobility were noted on examination. Conclusion: Conservative fixation of the anterior table does not appear to increase signs of nonunion in forehead reshaping gender-affirming surgery.
