Sugaleal hematoma usually develop one to eight days after minor head trauma or clotting disorders in children. The galeal aponeurosa in children is loosely attatched to the pericranium, allowing the collection of large quantity of blood. Most cases of subgaleal hematomas resolve spontaneously, however some cases require surgical intervention, aspiration of subgaleal hematoma often alleviate symptoms briefly and but do not shorten the time to resolution. Reaccumulation, infection following aspiration also had been reported. Here, we report the efficacy of using the blood donating set for the treatment of subgaleal hematoma in our series.

The authors present a case of subperisoteal orbital hematoma which is extended from subgaleal hematoma. A 15-year-old-male was admitted with a complaint of multiple visual symptoms of left eye following blunt head trauma. He has suffered from Wilson's disease. Several coagulative laboratory findings were abnormal(fibrinogen and coaguation factor V, X). Computed tomography, sonography and magnetic resonance imaging established the subperiosteal orbital extension of subgaleal hematoma into the orbital cavity. Needle aspiration of orbital subperiosteal hematoma was failed but symptoms and signs of the patient were much improved spontaneously following decrease of subgaleal hematoma. The literature is reviewed and management is discussed.

Subgaleal hematomas are accumulation of blood between periosteum and galea aponeurosis. A 2-year-old male Chihuahua was presented with a severe head swelling after trauma. Radiography and computed tomography (CT) showed a massive swelling encircling the entire calvarial vault, extending toward the cervical neck and crossing the suture line. It was heterogeneously, mild hyperdense fluid to soft tissue attenuating with contrast enhancement on CT images. On day 4, physical and imaging examination showed resolution of the calvarial swelling. Subgaleal hematoma should be considered as a differential diagnosis when there is a massive soft tissue swelling over the skull on physical and imaging examinations.

Not only is the concurrence of congenital myotonic dystrophy (CDM) and subgaleal hematoma (SGH) hardly ever seen but also the development of SGH during unassisted vaginal delivery is rare. We report a boy who developed huge SGH in vaginal delivery without any use of vacuum or forceps and later was diagnosed as maternally transmitted CDM. The boy had prenatal history of polyhydramnios and decreased fetal movement. Six hours after birth, severe molding of the skull associated with huge SGH on left parieto-occipital area was recognized by CT scan. At corrected age of two months, he was diagnosed as maternally transmitted CDM. This is the first report of CDM complicated by SGH occurring in non-instrumental vaginal delivery.

Objective : The purpose of this study is to identify any differential point in computerized tomographic[CT] findings between aneurysmal subarachnoid hemorrhage[ASAH] and traumatic subarachnoid hemorrhage[TSAH], which sometimes make us not confident in differentiation. Methods : CT of 142 ASAH and 82 TSAH patients over the last 2 years were retrospectively reviewed. We evaluated the thickness of SAH, the laterality of sylvian cisternal hemorrhage, the location, the number of involved cisterns, and the associated other lesions between two types of SAH. Results : Suprasellar cisterns and sylvian cisterns were most prominently and frequently involved cisterns in ASAH but cortical sulci and sylvian cisterns were most frequently involved in TSAH. Intraventricular and intracerebral hemorrhage were frequently seen in ASAH. Thickness of SAH over 1mm, bilateral sylvian SAH, multiple cisternal SAH were in favor of ASAH. The number of involved cisterns were more frequently seen in ASAH than in TSAH. In ASAH, bilateral sylvian hemorrhages were more frequently seen than in TSAH. Skull fracture, subdural hematoma, subgaleal hematoma, and hemorrhagic contusion were frequently associated with TSAH. Conclusion : As a result of our study, the authors conclude that when IVH, hydrocephalus, thick SAH > 1mm bilateral sylvian SAH, and multiple cisternal SAH are seen in CT, immediate angiography should be performed to rule out cerebral aneurysms whether associated with other traumatic lesions or not.

This report details a case of unexpected, severe post-operative cerebral edema following cranioplasty. We discuss the possible pathological mechanisms of this complication. A 50-year-old female was admitted to our department with sudden onset of stuporous consciousness. A brain computed tomography (CT) revealed a subarachnoid hemorrhage with intracranial hemorrhage and subdural hematoma. Emergency decompressive craniectomy and aneurysmal neck clipping were performed. Following recovery, the decision was made to proceed with an autologous cranioplasty. The cranioplasty procedure was free of complications. An epidural drain was placed and connected to a suction system during skin closure to avoid epidural blood accumulation. However, following the procedure, the patient had a seizure in the recovery room. An emergency brain CT scan revealed widespread cerebral edema, and the catheter drain was clamped. The increased intracranial pressure and cerebral edema were controlled with osmotic diuretics, corticosteroids, and antiepileptic drugs. The edema slowly subsided, but new low-density areas were noted in the brain on follow-up CT 1 week later. We speculated that placing the epidural drain on active suction may have caused an acute decrease in intracranial pressure and subsequent rapid expansion of the brain, which impaired autoregulation and led to reperfusion injury.

Purpose: A common side effect of the scalp reduction is a creation of a 'slot' with the hair growing in the opposite directions away from the scar. Overcoming the unnatural appearance of the slot has been a vexing problem in the scalp reduction surgery. None of the conventional corrective surgical techniques provides a complete and satisfactory aesthetic result. The Frechet flap is a triple transposition flap used for the correction of the slot defect secondary to scalp reduction surgery, seldom needing further scar revision. The Frechet technique provides a solution to the problem of the central slot concealment that is unattainable by other means, such as; Z-plasty and mini-graft. Methods: Authors applied the Frechet technique to Asian patients who had undergone scalp reduction and operated on 4 patients from March, 2000 to January, 2001. Average follow-up period was 13 months. Patients with long scars passing through the temporoparietoccipital zone were excluded. All the undermining was performed in the subgaleal plane, reaching the upper auricular sulcus and stopping just above the nuchal ridge. Results: None of the patients experienced infection, hematoma, nor any permanent hair loss. Transient telogen effluvium at the distal end of flap 2 and 3 was noticeable in one case. Conclusion: In conclusion, the results are aesthetically satisfactory without any significant complications.

Objective : Authors analyzed clinical outcomes of cranioplasty according to the materials used for covering defects of the skulls. Methods : From January 1997 to February 2000, there were forty one patients undergone cranioplasty at our institution. We used refrigerated autogenous bone flaps in 19 cases(group A) and methyl methacrylate(MMA) in 22 cases(group B). The medical records and plain skull radiographs of the patient were reviewed. Results : There were thirty men and eleven women. Mean follow up period was 12 months(From operation to last Outpatient department follow up). The mean operative time of the group A($136.8{\pm}3$ minutes) was shorter than the group B($172.7{\pm}2$ minutes, Mann-Whitney test, p=0.001). In group A, the degree of satisfaction was good in 8 cases, fair in 10, and poor in 1. In the group B, there were fair in 13 and poor in 9. So the cosmetic result was superior in the group A(Chi-square test, p=0.00). The complications were occured in one case of flap infection in the group A and 6 in the group B(one stitch abscess, 4 infected flaps, one subgaleal hematoma). Conclusion : Cranioplasty using refrigerated autogenous bone flap showed shorter operative time, better cosmetic results, and less complication rate than those using MMA.
