The correlation between skull fractures and intracranial lesions due to traffic accidents.

In this study, it was aimed to investigate the relationship between skull fractures and intracranial lesions following head injury. For this purpose, 500 cases, which were referred to the Third Committee of Council of Forensic Medicine in Istanbul due to traffic accidents by the courts of laws between 1998 and 2000, were examined retrospectively. They were categorized in 3 groups based on findings of their cranium x-rays and brain tomographies. 1- The cases who have fractures in skull bones with brain lesions 2- The cases who have fractures in skull bones with no brain lesions 3- The cases who have brain lesions with no skull fractures. They were examined in detail according to age, sex, localization of skull fractures and brain lesions, and if surgery was applied or not. Of the cases, 152 (30.4%) had only linear fractures, 69 (13.8%) had depressed fractures, 92 (18.4%) had linear fractures plus intracranial lesions, 49 (9.8%) had depressed fractures plus intracranial lesions and 138 (27.6%) had only intracranial lesions. The rate of intracranial lesion among the cases with the skull fracture was 38.9% (141/362), while the rate of skull fracture among the cases with the intracranial lesion was 50.3% (141/279) (P < 0.001). Male to female ratios were 2.4/1 for linear fractures, 5.2/1 for depressed fractures, and 3.5/1 for intracranial lesions. Linear fractures were more frequent among females whereas depressed fractures were often among males (chi2: 9.68, df: 4, p: 0.046). The mean age was 26.3. The rate of depressed fractures was higher the age groups of 0-30 years. (chi2: 16.28, df: 4, p: 0.003). Depressed fractures in the regions of frontal and parietal and, linear fracture in the regions of temporal and occipital were found at higher rates (P < 0.001). In conclusion, we reviewed skull fractures and/or intracranial lesions due to traffic accidents, and found depressed fractures to be more common among males whereas linear fractures to be more common among females and young males. In the male, the skull architecture is thicker and stronger than females and young males. We can state that presence of skull fractures lowers the incidence of intracranial lesions by lowering the intracranial pressure.

The incidence and prevention of meningitis after basilar skull fracture.

The survey of 1,077 consecutive skull fractures admitted to the Massachusetts General Hospital between July 1, 1969 and July 1, 1979 were reviewed. One hundred sixty-eight basilar skull fractures (15.6%) were diagnosed according to clinical and radiological criteria. In 128 patients with basilar skull fracture but without CSF leak, two out of 65 patients (3.1%) who received prophylactic antibiotics developed meningitis in contrast to none of 63 patients who were treated. Nine of 15 patients with otorrhea developed meningitis regardless of treatment. Of 18 patients with rhinorrhea, 13 were treated with prophylactic antibiotics and were free of meningitis but 2 of 5 patients not treated (40%) did develop meningitis. The overall incidence of CSF leak was 20.8%. There is no clear evidence to demonstrate that prophylactic antibiotics are effective in general in reducing the incidence of meningitis after basilar skull fracture with active rhinorrhea. However, the difference in the incidence of meningitis between the treated and the untreated group was noteworthy though not statistically significant. Meningitis can develop despite antibiotic prophylaxis. Additional investigation and therapy should be considered whenever the clinical situation warrants.

Delayed repair of open depressed skull fracture.

INTRODUCTION: Elevation and repair of an open depressed skull fracture is often thought of as an emergency procedure. Common indications for emergent elevation of a depressed skull fracture have been dural tear, seizure, gross contamination or mass effect from bone or a sizable underlying intracerebral hematoma. As treatment of head injury moves towards management of cerebral perfusion pressure (CPP) rather than intracranial pressure (ICP), we sought a way to maximize CPP in the initial treatment of head-injured patients with depressed skull fractures that would eventually require surgery by delaying surgery, when possible, until after the initial period of elevated ICP. METHODS: Over a 12-month period, 7 patients (all male, ages 1-15 years) were admitted to our institution with the diagnosis of open depressed skull fracture without significant mass effect requiring urgent decompression. All had significant head trauma with altered mental status and a Glasgow Coma Score of 3-12. Patients were treated with antibiotic prophylaxis (nafcillin, ceftriaxone, metronidazole), seizure prophylaxis (phenytoin) and underwent CPP management in an intensive care unit setting as indicated by intracranial pressure monitoring or clinical assessment. Length of medical management of CPP ranged from 4 to 12 days. Upon stabilization of CPP, patients were operated for repair of their dural, bone and scalp injuries. RESULTS: All 7 patients treated in the above manner suffered no ill effects from their delayed surgery: there was no meningitis, no late seizures, and no cerebrospinal fluid leak. Complications attributable to delay were not present at follow-up ranging from 12 to 24 months. CONCLUSIONS: We have delayed surgery for repair of open depressed skull fractures in order to maximize medical management of CPP in the setting of acute trauma. Among other considerations, the risk of intraoperative hypotension occurring at a time of acutely raised ICP was avoided by this delay. We conclude that there is a role, in this specifically defined subset of head trauma patients, for delayed surgical repair of open depressed skull fractures.

Antibiotic prophylaxis after basilar skull fractures: a meta-analysis.

Antibiotic prophylaxis after basilar skull fractures remains controversial. Previous studies have not clearly delineated the utility of prophylactic antibiotics in this setting. We undertook this study to determine if antibiotic prophylaxis after basilar skull fractures prevented meningitis. We performed a formal systematic review of previously published studies after a computerized search with use of the MEDLINE data base (1970-1996). Fourteen studies were identified, and 12 studies met the criteria for inclusion. Study design and quality were assessed by two independent investigators with use of a predetermined protocol. A total of 1,241 patients with basilar skull fractures were included; 719 patients received antibiotics, and 522 patients did not receive antibiotics. Overall results suggest that antibiotic prophylaxis did not prevent meningitis among patients with basilar skull fractures (odds ratio [OR] = 1.15; 95% confidence interval [CI] = 0.68-1.94; P = .678). Patients with basilar skull fractures and cerebrospinal fluid leakage were analyzed separately (OR = 1.34; 95% CI = 0.75-2.41; P = .358), as were children (OR = 1.04; 95% CI = 0.07-14.90; P = 1.000). Antibiotic prophylaxis after basilar skull fractures does not appear to decrease the risk of meningitis.

Growing skull fractures: classification and management.

Seven patients with growing skull fractures treated between 1983 and 1993 are described. These growing fractures constituted 1.6% of all the cases of skull fractures seen during the period (a total of 449 cases). Based on aetiopathogenesis, computed tomography (CT) appearances, operative findings and management strategies required, three main types of growing skull fractures were recognized. In type I (n = 3) a leptomeningeal cyst, in type II (n = 3) damaged and gliotic brain, and in type III (n = 2) a porencephalic cyst extended through the skull defect into the subgaleal space. A combination of type I and type III co-existed in one patient. Initial head injury and neurological deficit were judged to be mild to moderate in all the seven cases. Continued growth of skull fractures correlated closely to the increasing neurological deficit in five cases. In two patients natural arrest of fracture growth at 5 and 7 months after trauma was accompanied by arrest in progress of neurological deficit. Available surgical options are discussed and general guidelines for the management are given.

Intrauterine depressed skull fractures of the newborn.

Intrauterine depressed skull fractures are reported only occasionally. In reviewing the literature it seems clear that pressure of the fetal head against the maternal bony structures, mainly the sacral promontory, accounts for most of the so-called "spontaneous" congenital depressed skull fractures. Rather than true fractures, they are focal congenital moulding depressions. On the other hand, trauma to the mother's abdomen and traumatic delivery are accepted pathological mechanisms for such lesions; most commonly they are ascribed to inexpert application of the forceps blades or undue force by the obstetrician at the time of birth. In some cases, however, uncomplicated spontaneous vaginal or cesarean section deliveries have surprisingly and unexpectedly yielded infants with depressed skull fractures. Three such cases are reported, and the literature is reviewed.

Acute traumatic intracranial haematoma and skull fracture.

The value of plain skull radiographs in acute head injury has been much debated. A prospective study is presented of the isolated predictive value of skull fracture, in addition to the level of consciousness on admission after trauma, for acute intracranial haematoma. In head injuries which were followed by such haematoma, skull fracture was significantly more common than in injuries without this sequel. The association was found at all levels of consciousness and was most pronounced in patients with minor or no diminution of consciousness on admission. Fractures crossing a vascular groove had additional predictive significance.

Impact of skull fracture on neuropsychological functioning following closed head injury.

The role of skull fracture in affecting morbidity following closed head injury (CHI) has received a significant amount of attention from researchers. While there is fairly widespread agreement that skull fractures increase the risk of complications such as haematoma, it us unclear whether the presence of skull fracture has predictive value in terms of the neuropsychological sequelae of CHI. The purpose of the current study was to further investigate the role of skull fracture in predicting neuropsychological dysfunction following CHI. Subjects included patients admitted to the trauma service of a large teaching hospital who were suspected of having suffered CHI. All patients completed neuropsychological testing and had normal computerized tomography (CT) scans. Patients who had suffered skull fracture were compared to those who had not suffered skull fracture on selected neuropsychological measures. Groups did not differ in terms of CHI severity as assessed by the Glasgow Coma Scale (GCS). Multivariate analysis of variance revealed that the groups did differ in terms of neuropsychological functioning. Results are interpreted as suggesting that the presence of a skull fracture is predictive of additional neuropsychological dysfunction, even in the absence of intracranial pathology or more severe disturbance of consciousness on the GCS.

Rational management of simple depressed skull fractures in infants.

OBJECT: The management regimen for depressed skull fractures in infants can be conservative or surgical. The aim of this study was to provide a rational principle of management for simple depressed skull fractures in infants. METHODS: A protocol of nonsurgical treatment for a simple depressed skull fracture was designed for all affected infants during the period from 1985 to 2001. Conservative management was used for those with a depressed fracture measuring less than 5 mm in depth, whereas vacuum extraction was applied for larger and deeper depressions. All of the patients were evaluated for initial results and later outcomes. Twenty-five infants suffering simple depressed skull fractures were consecutively enrolled. According to our protocol, 11 patients received conservative management by close observation only. Spontaneous restoration of the depression was observed in eight patients within a period of 1 to 6 months. For the remaining 14 patients, vacuum extraction was performed. A negative pressure of 0.3 to 0.8 kg/cm2 (mean 0.49 kg/cm2) was applied for a duration of 20 to 90 seconds (mean 43.6 seconds). All but one patient experienced complete recovery following extraction. The depressions of the four patients that were residual after initial management smoothed out with time. No neurological deficit or later epilepsy was noted in any patient. CONCLUSIONS: Nonsurgical management can be the treatment of choice for infants with simple depressed skull fractures, whereas vacuum extraction is one option for larger and deeper depressions to obtain prompt resolution and relieve major family anxiety, without taking additional risks.

[Growing skull fracture in childhood. Presentation of 12 cases].

Growing skull fractures (GSF) are rare complications of head injury (HI) in childhood. This entity consists of a skull fracture with an underlying dural tear that courses with a progressive enlargement of the fracture to produce a cranial defect. The pathophysiology and some aspects of its management are still controversial. In this review we present 12 patients diagnosedd and treated for a GSF at our institution between 1980 and 2002. 11 patients were under the age of 3 years and one patient was 5 years old at the moment of HI. The most common cause of injury was a fall from height. In the initial plain x-rayfilms, 11 patients showed a diastatic skull fracture and one patient only had a linear fracture. At this time, CT scan showed cortical contussion underlying the fracture in every case. The mean time between injury and presentation of GSF was 11.6 weeks. Diagnosis was made by palpation of the cranial defect and confirmed with skull x-rayfilms. The most frecuent location of GSF was in the parietal region. Associated lesions like hydrocephalus, encephalomalacia, lepto-menigeal cysts, brain tissue herniation and ipsilateral ventricular dilatation, were found in the preoperative CT or MRI. All patients underwent a dural repair with pericranium or fascia lata. The cranial defect was covered with local calvarial bone fragments in every case. Only one patient needed a cranioplasty with titanium mesh. Every child with a skull fracture must be followed until the fracture heals. Patients under the age of 3 years with a diastatic fracture and a dural tear, demostrated by TC or MRI, are more prone to develop GSF. In these cases, early repair must be adviced in order to prevent progressive brain damage.

Spontaneous intrauterine linear skull fracture: a rare complication of spontaneous vaginal delivery.

BACKGROUND: Fetal skull fracture has been reported in conjunction with difficult delivery or extrinsic trauma. CASE: We report a case of linear, undisplaced, nondepressed skull fracture occurring in a 3540-g male infant born at 37 weeks and 4 days' gestation. Linear skull fracture occurred despite an uncomplicated spontaneous vaginal delivery in the absence of extrinsic trauma or cephalopelvic disproportion. Subsequent clinical follow-up 6 years later revealed normal neurological development without evidence of epileptiform activity or focal neurologic deficit. CONCLUSION: Linear skull fracture in association with uncomplicated, spontaneous vaginal delivery is distinctly rare, in contrast to focal, congenital molding depressions of the skull. This case demonstrates that normal spontaneous vaginal delivery without instrumentation or obvious complication can involve sufficient trauma to result in a linear skull fracture. The precise etiology of these fractures requires further study.

Growing skull fracture in a patient with cerebral hemiatrophy.

A growing skull fracture or leptomeningeal cyst most commonly occurs in children under the age of 3 years, and is extremely rare in adults. The reason for a growing skull fracture is usually a dural tear in association with the fracture. This paper presents an 18-year-old mentally retarded patient with cerebral hemiatrophy (Dyke-Davidoff-Masson syndrome) associated with a growing skull fracture in the ipsilateral hemicranium, in whom not only a dural tear but also the ipsilaterally displaced and dilated lateral ventricle due to the original disease apparently contributed to the development of growing skull fracture.

In utero skull fracture: case report.

In this report the authors discuss the unique case of a 19-year-old pregnant victim of a motor vehicle crash, who did not have significant injuries but in whom a fracture of the fetal skull was diagnosed. Several traumatic intrauterine fetal skull fractures have been reported over the last 100 years. In the vast majority of episodes, severe maternal trauma involving fractures of the pelvis has been causally related to the injured infant. There has not been a previous report of a motor-vehicle-associated fetal skull fracture in the absence of maternal injury with dual good outcomes. After cesarean section necessitated by fetal distress, both the baby and the mother made an excellent recovery. This case underscores the importance of a thorough examination of every pregnant trauma victim and her infant, even when there are no detectable maternal injuries.

Pediatric depressed skull fractures: analysis of 530 cases.

Depressed skull fractures (DSFs) account for 7-10% of children admitted to hospital with a head injury and 15-25% of children with skull fractures. We reviewed the records of 530 patients operated on for DSF from January 1, 1973, to December 31, 1993. This group was made up of 357 boys (67%) and 173 girls (33%) whose ages ranged from 1 day to 16 years (mean age 6.1 years). Fall was the most common cause of injury. Of the 530 patients with DSF, 66% had compound fractures. The incidence of compound fractures increased with age. Compound fractures caused more brain lacerations (29%) than simple fractures (15.5%) did. We also classified DSFs radiologically as true, flat, or ping-pong ball fractures. Associated intracranial lesions were found to be a bad prognostic factor. There were 13 deaths (2.5%) in this series. Satisfactory results were achieved in over 95% of the patients. Compound fractures are associated with a worse outcome and a higher incidence of intracranial lesions and cortical laceration. Unilateral pupillary dilatation and an admission GCS score of 8 or less are ominous signs in regard to mortality. We also found that the deeper the depressed bone, the higher the risk of both dural tear and cortical laceration and the worse the prognosis. A conservative approach should be followed in cases of simple DSF without associated intracranial hematoma and in cases in which the bone depression is not deeper than 1 cm.

The natural history of late diagnosed or untreated growing skull fractures: report on two cases.

Growing skull fractures (GSF) are rare complications of head trauma. Cases after childhood are extremely rare and demonstrate complicated pathological conditions which necessitate extensive treatment. We report on two rare cases of intracranial cysts related to growing skull fractures which are secondary to trauma sustained during childhood, and have been discovered in adolescence.
