Skull base fractures extend through the floor of the anterior, middle, or posterior cranial fossa. They are frequently associated with complex facial fractures and serious complications such as cranial nerve or vascular injury, cerebrospinal fluid leak, or meningitis. Several distinct patterns of skull base fractures have been recognized, each of them associated with different complications. Recognition of, often subtle, skull base fracture is essential to prevent or allow early treatment of these serious complications...

Fractures of the anterior skull base may occur in gunshot victims and can result in traumatic cerebrospinal fluid (CSF) leak. Less commonly, CSF leaks occur days or even weeks after the trauma occurred. Here, we present the case of a 21-year-old man with a delayed-onset, traumatic CSF leak secondary to a missile injury that left a bullet fragment in the Rosenmuller fossa. The patient was treated successfully with endoscopic, endonasal extraction of the bullet, and repair with a nasal septal flap. Foreign bodies lodged in Rosenmuller fossa can be successfully treated with endoscopic skull base surgery...

The purpose of this case report is to describe an interdisciplinary approach for a 51-year-old male who underwent multiple facial fractures including bilateral condyle fractures. The patient underwent emergency surgery, which included open reduction of the maxilla and mandibular symphysis and closed reduction of the bilateral condyle fractures. Although the patient recovered a comfortable range of mouth opening and alleviation of the temporomandibular joint (TMJ) symptoms after surgery, he suffered from a large anterior-posterior discrepancy due to less stability on the condyle-fossa relationships and from open bite with contacts only on both second molars and right second premolars...

Temporomandibular joint dislocation refers to the dislodgement of mandibular condyle from the glenoid fossa. Anterior and anteromedial dislocations of the mandibular condyle are frequently reported in the literature, but superolateral dislocation is a rare presentation. This report outlines a case of superolateral dislocation of an intact mandibular condyle that occurred in conjunction with an ipsilateral mandibular parasymphysis fracture. A review of the clinical features of superolateral dislocation of the mandibular condyle and the possible techniques of its reduction ranging from the most conservative means to extensive surgical interventions is presented...

OBJECTIVES: Routine transnasal rhinological procedures are widely practiced and are considered as safe, in general. Skull base lesions occur in less than 1% of procedures and typically involve the anterior or middle cranial fossa, while clivus lesions have not been well documented. Here we present a series of three patients with iatrogenic transclival lesions after routine transnasal rhinological procedures. PATIENTS AND METHODS: Three patients with penetrating clivus injuries after routine transnasal rhinological procedures were identified...

OBJECTIVE: the aim of this study is try to show the best view for distal radius fractures so called die-punch fractures. METHODS: There has been used a human cadaver radius bone from the Salvador Arena Tissue Bank. This bone was cleaned up after removing the soft tissues and osteotomies created displaced lunate fossa fractures of 0, 1, 2, 3 and 5 mm. We have fixed this fragment with adhesive tape. Then the joint deviation were significantly increased with step-offs of 1 mm...

The skull base is uniquely positioned to absorb force imparted to the craniofacial skeleton, thereby reducing brain injury. Less well understood is the effect of the direction of force imparted to the craniofacial skeleton on the severity of brain injury. Eighty-one patients from two UK major trauma centres who sustained a fronto-basal fracture were divided into two groups: those struck with predominantly anterior force and those by predominantly lateral force. The first recorded Glasgow Coma Score (GCS), requirement for intubation, and requirement for decompressive craniectomy were used as markers of the severity of brain injury...

OBJECTIVE Transfer of the spinal accessory nerve to the suprascapular nerve is a common procedure, performed to reestablish shoulder motion in patients with total brachial plexus palsy. However, the results of this procedure remain largely unknown. METHODS Over an 11-year period (2002-2012), 257 patients with total brachial plexus palsy were operated upon in the authors' department by a single surgeon and had the spinal accessory nerve transferred to the suprascapular nerve. Among these, 110 had adequate follow-up and were included in this study...

BACKGROUND: Intraorbital encephalocele is a rare entity characterized by the herniation of cerebral tissue inside the orbital cavity through a defect of the orbital roof. In patients who have experienced head trauma, intraorbital encephalocele is usually secondary to orbital roof fracture. CASE DESCRIPTION: We describe here a case of a patient who presented an intraorbital encephalocele 2 years after severe traumatic brain injury, treated by decompressive craniectomy and subsequent autologous cranioplasty, without any evidence of orbital roof fracture...

INTRODUCTION: Anterior and anteromedial dislocations of the mandibular condyle are seen frequently in mandibular fractures. Less frequent are dislocations of the condylar head in the lateral, medial and posterior direction whereas superior dislocation into the middle cranial fossa is rare. We report a series of seven cases encountered over the years, which, incidentally, is the largest case series reported till date with lateral and superolateral dislocation of the condyle after a traumatic injury...

The skull base is uniquely placed to absorb anteriorly directed forces imparted either via the midfacial skeleton or cranial vault. A variety of skull base fracture classifications exist. Less well understood, however, is fracture extension beyond the anterior cranial fossa (ACF) into the middle and posterior cranial fossae. The cases of 81 patients from two UK major trauma centres were studied to examine the distribution of fractures across the skull base and any relationship between the vector of force and extent of skull base injury...

Transorbital neuroendoscopic surgery (TONES) is a relatively new technique that not only allows access to the contents of the orbit but also the intracranial compartment, including the anterior cranial fossa, middle fossa and lateral cavernous sinus. In this study, we aimed to retrospectively review the largest experience to our knowledge with regards to surgical outcomes of skull base pathologies treated with a TONES procedure. Forty patients (aged 3-89 years) underwent 45 TONES procedures between the years of 2006-2013...

BACKGROUND: Transverse pediatric supracondylar fractures through the midolecranon fossa are frequently encountered and modeled in biomechanical studies. Our objective is to investigate the optimal pin configurations for low, sagittal oblique, and high fracture varieties that have not been previously investigated. METHODS: A total of 100 synthetic composite pediatric humeri were tested. Three groups of 30 were used to simulate 1 of 3 fracture variations. Subgroups of 10 were stabilized with 2 lateral pins (2LP), 3 lateral pins (3LP), or cross K-wires (XP)...

We report a 53-year-old man who sustained severe facial and base of skull fractures. At the scene of his accident he had Epistats (Medtronic Sofamor Danek, Memphis, TN, USA) placed for control of his severe nasal haemorrhage, subsequently resulting in the migration of one Epistat into the anterior cranial fossa. There are numerous reports of inadvertent intracranial placement of medical equipment, predominantly in association with complex facial and skull trauma. Other factors that can predispose to aberrant location include previous anterior cranial base surgery and lesions affecting structures in that area...

H Claude Sagi, Brett Bolhofner
The lateral "window" has previously been described as part of the ilioinguinal and anterior intrapelvic approaches for gaining access to the anterior aspect of the sacroiliac joint, the internal iliac fossa, and upper portion of the anterior column for reduction and placement of fixation. Surgical exposure of this window typically involves release of the external oblique muscle from the iliac crest and elevation of the iliacus muscle from the internal iliac fossa. This exposure is limited by the residual attachment of the external oblique muscle and inguinal ligament to the anterior superior iliac spine, particularly in patients with a large abdomen or in fractures that involve the anterior wall of the acetabulum and pubic root region...

OBJECTIVE: The goals of a tissue-preserving minimally invasive approach to the hip are to allow early short-term recovery, achieve hip joint stability, minimize muscle strength loss from surgery, spare the peri-articular soft tissues, and allow unrestricted motion in the long term. INDICATIONS: Hip arthroplasty in patients with no pre-existing hardware, with a sufficient space between the acetabular rim and greater trochanter; management of subcapital femoral fractures in older patients...

The technology adoption and creation of a multidisciplinary team have helped to overcome the complexity associated. Craniofacial surgery has thus emerged from the valuable contributions of neurosurgery, maxillofacial surgery, plastic surgery, eyes, nose, and throat as well as head and neck surgery. A patient with trigonocephaly may present a prominent "keel" forehead, accompanied by recession of the lateral orbit rims, hypotelorism, and constriction of the anterior frontal fossa when the metopic suture fuses before 6 months of age...

Kyoichi Matsuzaki, Sayaka Enomoto, Tomoko Aoki
In orbital roof blow-up fractures, reduction can be achieved easily using an approach from the anterior cranial fossa but the procedure is highly invasive. In contrast, an orbital approach using a superior blepharoplasty incision is minimally invasive. However, if bone fragments are adhered to the dura mater, there is a risk of dura mater injury when fragments are moved for reduction. In blow-in fractures, reduction is performed by pushing the bone fragments against the anterior cranial fossa. In contrast, the procedure is difficult for blow-up fractures because bone fragments must be pulled out into the orbit through the anterior cranial fossa...

BACKGROUND: Osteomalacia-inducing tumors (OIT) are mesenchymal tumors that characteristically secrete fibroblast growth factor 23, resulting in a paraneoplastic syndrome of hypophosphatemic osteomalacia. These tumors are known to occur in soft tissues and bones in various sites. It is very unusual for OITs to occur intracranially, with only 10 reported intracranial cases since their discovery in 1959. The most common intracrainal OITs are phosphaturic mesenchymal tumors and hemangiopericytomas...
