ABSTRACT
Temporal bone (TB) fractures are frequently accompanied by intracranial injury. This study aimed to analyze combined intracranial injuries in relation to functional changes in the inner ear, including those of the contralateral ear, in patients with TB fractures. Ninety-four patients (mean age: 35.6 ± 18.7 years, M : F=67 : 27) diagnosed with unilateral TB fracture were included. Bone conduction (BC) threshold, word recognition score (WRS), and changes in vestibular function were compared based on intracranial injuries, focusing on the contralateral side. Various types of intracranial injuries were observed (67.9%). Among these, a significant association between traumatic brain injury (TBI) and otic capsule-violating fractures was noted. The BC threshold on the fractured side significantly deteriorated in patients with TBI. Additionally, a significantly worse BC threshold was confirmed on the contralateral side in patients with TBI, intracranial hemorrhage (ICH), and contrecoup injury. The follow-up BC threshold did not improve or differ, regardless of high-dose steroid administration. The initial WRS and canal paresis in the bithermal caloric test were not significantly different in the presence of each intracranial injury. Concurrent fluctuations in the pressure of the cerebrospinal fluid space and perilymphatic space were speculated to be the potential underlying mechanisms. A significantly worse BC threshold was confirmed on the contralateral side of patients with TBI, contrecoup injury, ICH, and on fracture sides of patients with TBI.

INTRODUCTION: Inpatient and outpatient evaluation is important for management of temporal bone trauma due to the possible otologic complications that can result. However, there is limited literature on follow up rates following temporal bone fracture. This study aimed to determine the proportion of patients lost to follow up after sustaining temporal bone fractures and identify factors associated with loss to follow up. METHODS: Retrospective review of adult patients who sustained temporal bone fractures at a level I trauma center from January 1, 2019 to January 1, 2024 was completed (IRB H-44161). The primary outcome included prevalence of patient loss to follow up. Secondary variables included initial radiographic and exam findings, otologic complications, and demographic characteristics. Patients who were seen in follow up and lost to follow up were compared, and odds of loss to follow up was calculated. RESULTS: Sixty-nine patients met inclusion criteria for this study, of which 30 patients (43.5%) were lost to follow up. Patients who were White had a significantly lower odds of loss to follow up than those who were not White (OR = 0.2506 (95% CI: 0.0706, 0.8067, P = .0024). While need for acute management was not significantly different between the groups, a significantly lower proportion of patients who were intubated on presentation (P = .0091), had abnormal otoscopic exam (P = .0211), and had otologic complications (P = .0056) were lost to follow up. CONCLUSION: Almost half of patients who sustained temporal bone fractures, including a significantly higher odds of minority race/ethnicity patients, were lost to follow up.

BACKGROUND: Traumatic brain injury (TBI) with skull fractures parallel to or crossing venous sinuses is a recognized risk factor for traumatic cerebral venous sinus thrombosis (tCVST). Despite the recognition of this traumatic pathology in the literature, no consensus regarding management has been achieved. This study aimed to evaluate the impact of tCVST on TBI outcomes and related complications. METHODS: Patients within a prospective registry at a level I trauma center from 2014 to 2023 were reviewed to identify tCVST cases. The impact of tCVST presence on Glasgow Outcome Scale scores at 6 months, 30-day mortality, and hospital length of stay were evaluated in multivariable-adjusted analyses. RESULTS: Among 607 patients with TBI, 61 patients were identified with skull fractures extending to the vicinity of venous sinuses with dedicated venography. Twenty-eight of these 61 patients (44.3%) had tCVST. The majority (96.4%) of tCVST were located in a unilateral transverse or sigmoid sinus. Complete recanalization was observed in 28% of patients on follow-up imaging (7/25 with follow-up imaging). None of the 28 patients suffered attributable venous infarcts or thrombus propagation. In the adjusted analysis, there was no difference in the 30-day mortality or Glasgow Outcome Scale at 6 months between patients with and without tCVST. CONCLUSIONS: Unilateral tCVST follows a benign clinical course without associated increased mortality or morbidity. The management of tCVST should be distinct as compared to spontaneous CVST, likely without the need for anticoagulation.

PURPOSE: The purpose of this study was to analyze the prevalence of and complications resulting from temporal bone fractures in adult and pediatric patients evaluated for cranio-facial trauma in an emergency setting. METHODS: A retrospective blinded analysis of CT scans of a series of 294 consecutive adult and pediatric patients with cranio-facial trauma investigated in the emergency setting was conducted. Findings were compared between the two populations. Preliminary reports made by on-call residents were compared with the retrospective analysis, which was performed in consensus by two experienced readers and served as reference standard. RESULTS: CT revealed 126 fractures in 116/294 (39.5%) patients, although fractures were clinically suspected only in 70/294 (23.8%); p < 0.05. Fractures were longitudinal, transverse and mixed in 69.5%, 10.3% and 19.8% of cases, respectively. Most fractures were otic-sparing fractures (95.2%). Involvement of the external auditory canal, ossicular chain and the osseous structures surrounding the facial nerve was present in 72.2%, 8.7% and 6.3% of cases, respectively. Temporal bone fractures extended into the venous sinuses/jugular foramen and carotid canal in 18.3% and 17.5% of cases, respectively. Vascular injuries (carotid dissection and venous thrombosis) were more common in children than in adults (13.6% versus 5.3%); however, the observed difference did not reach statistical significance. 79.5% of patients with temporal bone fractures had both brain injuries and fractures of the facial bones and cranial vault. Brain injuries were more common in adults (90.4%) than in children (63.6%), p = 0.001. Although on-call residents reliably detected temporal bone fractures (sensitivity = 92.8%), they often missed trauma-associated ossicular dislocation (sensitivity = 27.3%). CONCLUSIONS: Temporal bone fractures and related complications are common in patients with cranio-facial trauma and need to be thoroughly looked for; the pattern of associated injuries is slightly different in children and in adults.

PURPOSE OF REVIEW: To present the current literature on management of facial nerve disorder secondary to trauma, with a focus on the utility of electrodiagnostic testing in this setting. RECENT FINDINGS: Patients with facial palsy related to temporal bone fractures should be started on high-dose corticosteroids as early as possible. Recent literature on the benefit of surgical intervention in the setting of temporal bone fracture is mixed. Some studies support early surgical decompression whereas others have found no benefit compared with conservative treatment. SUMMARY: The management of facial nerve trauma is based on location and extent of injury. Extratemporal trauma and transected nerve should be treated with surgical exploration and tension-free coaptation ideally within 72âh. There are no guidelines for intratemporal facial nerve trauma. Surgical decompression compared with medical management is debated in the literature without consensus and more large studies are needed.

BACKGROUND/AIM: Results of studies investigating the association between traumatic brain injury (TBI) and maxillofacial fractures (MFs) have varied considerably. The present study aimed to evaluate the correlation between TBIs and MFs, as well as the impact of age, sex, trauma mechanism, and season on TBIs. MATERIALS AND METHODS: This 12-year retrospective study of 2841 patients used univariate and multivariate logistic regression to assess the association between MFs and other factors impacting TBIs. RESULTS: Among 2841 patients, 1978 TBIs occurred in 829 (29.2%), with intracranial injuries (n = 828) is the most common. Of 829 patients with TBIs, 688 were male and 141 were female, corresponding to a male-to-female ratio of 4.9:1.0. The most common age group was 40-49 years (24.6%). Vehicles (including motor vehicles and electric vehicles) accidents were the primary causes of injuries. Multivariate regression analyses revealed an increased risk for TBIs among males (odds ratio [OR] 0.632, p < 0.001). Patients >40 years of age were at higher risk for TBIs, especially those ≥70 years (OR 3.966, p = 0.001). Vehicle accidents were a high-risk factor for TBIs (OR 6.894, p < 0.001), and winter was the most prevalent season for such injuries (OR 1.559, p = 0.002). Risk for TBI increased by 136.4% in combined midfacial and mandibular fractures (p = 0.016) and by 101.6% in multiple midfacial fractures (p = 0.045). TBIs were less common in single mandibular fractures, notably in single-angle fractures, with a risk of only 0.204-fold. CONCLUSION: TBIs in MFs were significantly correlated with sex, age, aetiology, season and fracture location. Maxillofacial surgeons and emergency physicians must be aware of the possible association between TBIs and MFs to assess and manage this complicated relationship in a timely manner.

BACKGROUND: Limited retrospective data suggest that dural venous sinus thrombosis (DVST) in traumatic brain injury (TBI) patients with skull fractures is common and associated with significant morbidity and mortality. Prospective data accurately characterizing the incidence of DVST in patients with high-risk TBI are sparse but are needed to develop evidence-based TBI management guidelines. METHODS: After obtaining institutional approval, 36 adult patients with TBI with skull fractures admitted to an Australian level III adult intensive care unit between April 2022 and January 2023 were prospectively recruited and underwent computed tomography venography or magnetic resonance venography within 72 hours of injury. When available, daily maximum intracranial pressure was recorded. RESULTS: Dural venous sinus abnormality was common (36.1%, 95% confidence interval 22.5%-52.4%) and strongly associated with DVST (P = 0.003). The incidence of DVST was 13.9% (95% confidence interval 6.1%-28.7%), which was lower than incidence reported in previous retrospective studies. Of DVSTs confirmed by computed tomography venography, 80% occurred in patients with extensive skull fractures including temporal or parietal bone fractures in conjunction with occipital bone fractures (P = 0.006). However, dural venous sinus abnormality and DVST were not associated with an increase in maximum daily intracranial pressure within the first 7 days after injury. CONCLUSIONS: Dural venous sinus abnormality was common in TBI patients with skull fractures requiring intensive care unit admission. DVST was confirmed in more than one third of these patients, especially patients with concomitant temporal or parietal and occipital bone fractures. Computed tomography venography is recommended for this subgroup of TBI patients.

BACKGROUND: Patients with traumatic brain injuries (TBIs) often experience concurrent facial bone fractures. In 2021, a prediction model with 10 variables was published and precisely predicted concomitant facial fractures in TBI patients. Herein, external validation and simplification of this model was performed. METHODS: Traumatic brain injury patients treated at a major referral trauma center were retrospectively reviewed for 1 year. The original prediction model (published in 2021), which was developed from a rural level II trauma center, was applied for external validation. A new and simplified model from our level I trauma center was developed and backwardly validated by rural level II trauma center data. RESULTS: In total, 313 TBI patients were enrolled; 101 (32.3%) had concomitant facial fractures. When the previous prediction model was applied to the validation cohort, it achieved acceptable discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.713 and good precision, with a Brier score of 0.083. A new and simplified model with 6 variables (age, tooth rupture, epistaxis, facial lesion, eye injury, and intracranial hemorrhage) was created with excellent discrimination (AUC = 0.836) and good precision (Brier score of 0.055). The backward validation of this new model also showed excellent discrimination in the cohort used to develop the original model (AUC = 0.875). CONCLUSION: The original model provides an acceptable and reproducible prediction of concomitant facial fractures among TBI patients. A simplified model with fewer variables and the same accuracy could be applied in the emergency department and at higher- and lower-level trauma centers.

CONTEXT: Penetrating craniocerebral injury associated with depressed skull fracture is an infrequent yet timely neurosurgical emergency. Such injury frequently occurs in the frontal region during traffic accident or stone throw in the civilian setting. As military neurosurgeons, we present our experience in the surgical debridement and reconstruction of this peculiar type of traumatic brain injury. METHODS: The patient lies supine, the head in neutral position heal by a Mayfield head clamp. The first step is the debridement of the frontal wound. Then, the depressed skull fracture is operated on using a tailored coronal approach through Merkel dissection plane, in order to keep a free pericranial flap. The bone flap is cut around the depressed skull fracture. Neuronavigation allows to locate the frontal sinus depending on whether it has been breached and thus requires cranialization. Brain and dura mater debridement and plasty are performed. Cranioplasty is performed using either native bone fragments fixed with bone plates or tailored titanium plate if they are too damaged. CONCLUSION: Performing wounded skin closure first and then a tailored coronal approach with free pericranial flap and a craniotomy encompassing the depressed skull fracture allows to treat frontal penetrating craniocerebral injury in an easy-to-reproduce manner.

OBJECTIVE: To analyze the rates of complications after pediatric temporal bone fractures (TBF) and the utility of the longitudinal, transverse, and mixed versus the otic capsule sparing (OCS) and otic capsule violating (OCV) classification systems in predicting these complications. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: Per PRISMA guidelines, studies of children with TBFs were included. Meta-analyses of proportions were performed. RESULTS: A total of 22 studies with 1376 TBFs were included. Children with TBF had higher rates of conductive hearing loss (CHL) than sensorineural hearing loss (SNHL) (31.3% [95% confidence interval [CI] 23.2-40.1] vs 12.9% [95% CI 8.9-17.5]). No differences in both CHL and SNHL were seen between longitudinal and transverse TBFs; however, OCV TBFs had higher rates of SNHL than OCS TBFs (59.3% [95% CI 27.8-87.0] vs 4.9% [95% CI 1.5-10.1]). Of all patients, 9.9% [95% CI 7.2-13.1] experienced facial nerve (FN) paresis/paralysis, and 13.4% [95% CI 5.9-23.2] experienced cerebrospinal fluid otorrhea. Transverse TBFs had higher rates of FN paresis/paralysis than longitudinal (27.7% [95% CI 17.4-40.0] vs 8.6% [95% CI 5.2-12.8]), but rates were similar between OCS and OCV TBFs. CONCLUSION: CHL was the most common complication after TBF in children; however, neither classification system was superior in identifying CHL. The traditional system was more effective at identifying FN injuries, and the new system was more robust at identifying SNHL. While these results suggest that both classification systems might have utility in evaluating pediatric TBFs, these analyses were limited by sample size. Future research on outcomes of pediatric TBFs stratified by type of fracture, mainly focusing on long-term outcomes, is needed.

BACKGROUND: Management of facial fractures is variable. Understanding how time to operative management impacts outcomes can help standardize practice. METHODS: Retrospective analysis of the ACS Trauma Quality Improvement Program (TQIP) database between 2016 and 2019. Adult patients with operative facial fractures were isolated by ICD-10 procedure codes, and further stratified by fracture location, including the mandible, orbit, maxilla, zygoma, and frontal bone. Multivariable logistic regression was conducted to predict in-hospital complications (both surgical and systemic complications) adjusting for time-to-operation, comorbidities, fracture location, AIS, and demographics. RESULTS: 1678 patients with operative facial fractures were identified. The median time-to-operation was 2 days (IQR 1.0-2.0 days). Most patients only had one operative fracture (95 %) and orbital fracture was the most common (44 %). The overall complication rate was higher for those operated after 2 days compared to those operated between 1 and 2 days and within 24 h (2.8 % vs 0.6 % vs 0.7 %; p < 0.001). Patients who were operated on after 48 h exhibited an increased risk of any complication (OR 4.72, 95 % CI 1.49-16.6, p = 0.010) on multivariable models. CONCLUSION: Delays in the management of facial fractures are associated with more in-hospital complications. However, the incidence of short-term postoperative complications remains low. Injury characteristics are the primary predictor of delays in operation, however Hispanic patients independently experienced delays in care.

BACKGROUND AND PURPOSE: Alcohol withdrawal seizures (AWS) are a well-known complication of chronic alcohol abuse, but there is currently little knowledge of their long-term relapse rate and prognosis. The aims of this study were to identify risk factors for AWS recurrence and to study the overall outcome of patients after AWS. METHODS: In this retrospective single-center study, we included patients who were admitted to the Emergency Department after an AWS between January 1, 2013 and August 10, 2021 and for whom an electroencephalogram (EEG) was requested. AWS relapses up until April 29, 2022 were researched. We compared history, treatment with benzodiazepines or antiseizure medications (ASMs), laboratory, EEG and computed tomography findings between patients with AWS relapse (r-AWS) and patients with no AWS relapse (nr-AWS). RESULTS: A total of 199 patients were enrolled (mean age 53 ± 12 years; 78.9% men). AWS relapses occurred in 11% of patients, after a median time of 470.5 days. Brain computed tomography (n = 182) showed pathological findings in 35.7%. Risk factors for relapses were history of previous AWS (p = 0.013), skull fractures (p = 0.004) at the index AWS, and possibly epileptiform EEG abnormalities (p = 0.07). Benzodiazepines or other ASMs, taken before or after the index event, did not differ between the r-AWS and the nr-AWS group. The mortality rate was 2.9%/year of follow-up, which was 13 times higher compared to the general population. Risk factors for death were history of AWS (p < 0.001) and encephalopathic EEG (p = 0.043). CONCLUSIONS: Delayed AWS relapses occur in 11% of patients and are associated with risk factors (previous AWS >24 h apart, skull fractures, and pathological EEG findings) that also increase the epilepsy risk, that is, predisposition for seizures, if not treated. Future prospective studies are mandatory to determine appropriate long-term diagnostic and therapeutic strategies, in order to reduce the risk of relapse and mortality associated with AWS.

Background: Maxillofacial Injury (MFI) is a major public health concern that is multifactorial in etiology-road traffic accidents (RTAs), falls and violence. RTAs are the major cause of maxillofacial injuries (MFIs) in countries like India. Recent studies have shown that maxillofacial fractures (MFF) constitute a significant proportion of facial injuries seen in hospitals (56.5%). The incidence of maxillofacial fractures can vary depending on several factors, including age, gender, and environmental factors. Of particular concern is the impact of seasonal variations, such as the monsoon season, which lead to high incidence of maxillofacial fractures due to hazardous conditions. Methods: A retrospective review of medical records was done in a tertiary-care dental teaching hospital was done. Results: Data of 200 subjects including 154 males (77%) and 46 females (23%) with a mean age of 35.38 ± 16.541 years; age range: 1 - 80 years was analyzed. A total of 200 MFI's were recorded between 2021 and 2022. Soft tissue injuries were reported in 37.5% of the cases in non-monsoon season and 42.3% of the cases during the monsoon season. Dentoalveolar fractures were reported in 6.2% of the cases during the non-monsoon seasons and 7.7% during the monsoon season. In this study, mandible was the most fractured bone (n=104,52%) followed by zygomatic complex (n=50, 25%). The frequently observed pattern among mandibular fracture was condyle 8.3% during the non-monsoon season and 2.9% during the monsoon season). Conclusions: The results of the study indicate that mandibular fractures are most commonly seen in maxillofacial fractures, followed by fractures of the zygomatic complex. The study also reveals a higher incidence of soft tissue injuries and dentoalveolar fractures during the monsoon season. Further research is warranted to explore the factors that contribute to the seasonal variation in maxillofacial fractures for effective interventions to reduce their occurrence.

Background: Temporal bone fracture is usually a sequel of significant blunt head injury. Fracture of the temporal bone is mainly classified according to the orientation of the fracture plane and whether there is involvement of the otic capsule. Despite its frequent occurrence, there is limited research on the frequency and pattern of temporal bone fractures in our setup. Methods: Retrospective cross-sectional hospital - based study of 60 patients who underwent computed tomography of the head for head trauma at Tikur Anbessa Specialized Hospital during the study period from October 2020 - October 2022. Results: Among the 60 patients enrolled in the study, the mean age of presentation was 31.1 years with a male-to-female ratio of 4:1. There were 69 temporal bone fractures, 9(15%) were bilateral and 51(85%) unilateral The longitudinal fracture pattern was the most common fracture pattern, occurring in 40(78.4%) of unilateral cases, 15(83.3%) of bilateral cases. Otic capsule sparing fractures accounted for 49(96.07%) of unilateral fracture cases, and all patients with bilateral involvement had an otic capsule sparing fracture. Among the 42 patients for whom data regarding post-traumatic hearing outcome was available, 4 patients had post-traumatic hearing impairment. Anatomically, the squamous portion of the temporal bone was involved in 30(43.5%) of cases. Conclusions: Fractures affecting the squamous portion of the temporal bone, longitudinal fracture patterns, and otic capsule sparing were the most frequent forms. The majority of temporal bone fractures were associated with other bone fractures and intracranial injuries.

Abstract The surgical management of firearm injuries to the zygomaticomaxillary complex is a topic that needs to be addressed with much care. The complications that can arise during treatment, as well as the potential residual problems that can appear, lead to the need of recognizing these injuries as a maxillofacial treatment challenge. The infraorbital zone is the second most common area of injury in the face, accounting for up to 45% of midfacial fractures. The case presented is of a 54 year old man affected by the backward firing of a gun rifle that caused an oblique impaction towards the posterior lateral inferior side of the infraorbital complex. He was rapidly stabilized with an antibiotic and analgesic scheme, yet presented the following: a comminute fracture of the orbit floor with consequent communication towards the maxillary sinus, a non-displacing fracture of the frontomalar suture, a non-displacing fracture of the zygomatic arch and a lesion with loss of osseous tissue in the petrous region of the temporal bone. Rigid fixation followed stabilization, and the area was covered with a titanium mesh. Occasional tinnitus and photopsia were reported by the patient upon return, yet all other evaluated factors were in order. There have been different forms of management described in the literature, and it is recognized that each patient has different needs, therefore each case must be closely evaluated, so it is approached in the most appropriate manner.
Resumen El manejo quirúrgico de las lesiones por armas de fuego al complejo cigomaticomaxilar representa una situación compleja en la práctica maxilofacial que debe ser abordada con extrema cautela, debido a las complicaciones que pueden surgir durante el tratamiento y los potenciales problemas residuales. La zona infraorbitaria es la segunda área más común de lesiones en la cara, representando hasta 45% de las fracturas mediocraneales. El presente caso es de un masculino de 54 años de edad, que sufrió trauma ocasionado por la parte trasera de un rifle de caza que causó un impacto en sentido oblicuo hacia el lado lateral inferior del complejo infraorbitario. El paciente fue estabilizado con esquema antibiótico y analgésico, el diagnóstico fue: fractura cominuta del piso de la órbita, con consecuente comunicación al seno maxilar, fractura no desplazada de la sutura frontomalar, fractura no desplazada del arco cigomático, y lesión con pérdida de tejido óseo en la región petrosa del hueso temporal. El tratamiento quirúrgico consistió en reducción de las fracturas y fijación rígida de las estructuras. Al control post operatorio el paciente refirió acufenos y fotopsia ocasional, no presentando otras alteraciones. Se ha descrito en la literatura diferentes abordajes para el manejo de estos traumatismos, sin embargo cada caso debe ser individualizado y evaluado de forma minuciosa para que éste, sea el adecuado.

Describimos el caso de una paciente femenina de 5 años de edad, con antecedente de fractura craneal asociado a trauma directo en su segundo día de vida, posteriormente se diagnostica quistes porencefálico y aracnoideo frontoparietal izquierdo a los 3 meses de edad. Fue tratada en un primer momento con la colocación de sistema derivativo cistoperitoneal, y se le realizaron estudios de imágenes de seguimiento. A los 5 años de edad es traída a consulta de nuestro servicio de neurocirugía, por presentar deformidad calvarial en la superficie frontoparietal izquierda. El seguimiento con tomografía de cráneo demostró un cese relativo en la progresión en las dimensiones del quiste porencefálico y aumento del espacio entre los bordes óseos de la fractura. La paciente fue llevada a mesa operatoria, en la cual se realizó un abordaje hemicoronal izquierdo con resección de tejido gliótico, duroplastia con pericráneo y colocación de craneoplastía con tejido óseo craneal autólogo. El seguimiento al mes de la intervención correctiva mostró evolución satisfactoria y sin complicaciones. La cirugía correctiva de la fractura evolutiva, debe realizarse en el momento del diagnóstico para evitar su expansión. En concordancia con la teoría de Moss, se observa aumento del espacio entre los bordes de la fractura, aún con la disminución de la presión intracraneal al derivar el líquido cefalorraquídeo. En este caso, la intervención correctiva de la fractura, determinó una evolución satisfactoria, en ausencia de hidrocefalia o crisis convulsiva, posiblemente debida a la presión disminuida del quiste porencefálico sobre el parénquima subyacente.
We describe the case of a female patient of five years old, with a history of a skull fracture associated with direct trauma on his second day of life, then porencephalic left frontoparietal arachnoid cysts was diagnosed at 3 months of age. She was iniatially treated by plaing cystoeritoneal derivative system and follow-up imaging studies was performed. At 5 years of age is brought to clinic in our departmen of neurosurgery, for presenting calvarial deformity in the left frontoparietal area. The follow-p scan of the head showed a cease progression relative dimensions porencephalic cyst an increased space between the bone edges of the fracture. The patient was transferred to operating table, on which a hemicoronal left gliotico approach with resection of tissue was performed with dural graft placement craneoplasty bone tissue. Monitoring the month showed satisfactory corrective intervention and hassle evolution was performed with dural graft placement craneoplasty scalp and skull with autologous bone tissue. Corrective surgery of evolutionary fracture should be performed at the time of diagnosis to prevent its expansion. In agreement with the Moss theory, increasing the space between the edges of the fracture even with decreasing intracranial pressure deriving the cerebrospinal fluid was observed. In this case corrective intervention of the fracture produced a satisfactory outcome in the absence of hydrocephalus or seizure, possibly due to decreased pressure of porencephalic cyst on the underlying parenchyma.

É bem estabelecido que o diagnóstico da fratura de côndilo occipital tem aumentado nas últimas décadas, provavelmente devido à disponibilidade e ao uso comum da tomografia computadorizada durante a investigação do trauma craniano, além da maior gravidade dos mecanismos de trauma. Por causa da baixa especificidade da apresentação clínica, e também pelo pouco conhecimento sobre o mecanismo de lesão, o diagnóstico desta condição é um desafio para neurocirurgiões. A abordagem terapêutica destes pacientes é baseada em estudos com baixa casuística e em relatos de caso. Uma revisão sobre este tema foi realizada a fim de discutir alguns aspectos controversos sobre o manejo da fratura de côndilo occipital. As fraturas de côndilo occipital são eventos raros, entretanto podem relacionar-se à alta morbidade em pacientes que sofreram trauma encefálico. Alguns sintomas, como intensa dor cervical, podem estar associados com esta fratura; portanto, paciente com suspeita de fratura de côndilo occipital deve ser submetido a investigação radiológica detalhada da região. O diagnóstico precoce desta fratura permite investigação apropriada, minimizando a chance de sequelas.
It is well established that diagnoses of occipital condyle fracture have increased in past decades, probably because of the availability and common use of computed tomography for investigating traumatic brain injuries, as well as themajor seriousness of trauma mechanism. Because of the low specificity of clinical presentation besides the lesion mechanism not well known, this condition is a diagnostic challenge for neurosurgeons. Therapeutic approaches of these patients are based on studies with low samples and case reports. A review of this theme was performed objecting to discuss some controversial topics about management of occipital condyle fracture. The occipital condyle fracture is a rare event, and it, however, could be related to high morbidity in patients who suffered traumatic brain injury. Some symptoms such as severe neck pain are related with this fracture, and thus patients suspicious of this fracture should undergo detailed radiologic investigation of this region. Early diagnosis of this fracture allows appropriate investigation, thus minimizing the risk of sequelae.
