BACKGROUND: Frontoethmoidal schwannomas are rare. No case manifesting exertional cerebrospinal fluid (CSF) rhinorrhea has ever been reported to the best of our knowledge. CASE DESCRIPTION: In this report, we describe an extremely rare case of frontoethmoidal schwannoma extending through the olfactory groove (OG) with exertional CSF rhinorrhea as the initial symptom. A 50-year-old woman was presented to our clinic for frequent nasal discharge on exertion. A postcontrast computed tomographic scan demonstrated heterogeneously enhanced tumor from the anterior cranial fossa to the anterior ethmoid sinus...

Case summary: Cranial ventral midline hernias, most often congenital, can be associated with other congenital abnormalities, such as sternal, diaphragmatic or cardiac malformations. A 4-year-old multiparous queen with a substernal hernia was admitted for evaluation of a mammary mass. During CT examination, a bifid sternum, the abdominal hernia containing the intestines, spleen, omentum, three fetuses, a mammary mass and an incidental peritoneopericardial diaphragmatic hernia were identified...

BACKGROUND: No high-fidelity animal model exists to examine prospective wound healing following vascularized reconstruction of the skull base. Such a model would require the ability to study the prospective behavior of vascularized mucosal repairs of large dural and arachnoid defects within the intranasal environment. The objective of this study was to therefore develop and validate a novel, in vivo, transfrontal sheep model of cranial base repair using vascularized sinonasal mucosa. METHODS: Twelve transfrontal craniotomy and 1...

Electrical burns are group of traumatic injuries with a mortality rate of 3-15%. High-voltage induced extensive electric burns are rarely seen in the cranial area, compared to upper and lower limbs, but extremely difficult for treatment, due to the limited flexibility in this area. The spectrum of therapeutic interventions in electrical burns in general, evolving initial necrectomy, decompression, and aggressive debridement with early skin coverage is usually not enough in cases of extensive cranial defects...

Somatosensory evoked potentials (SSEPs) are used for neuroprognosis after severe traumatic brain injury (TBI). However decompressive craniectomy (DC), involving removal of a portion of the skull to alleviate elevated intracranial pressure, is associated with an increase in SSEP amplitude. Accordingly, SSEPs are not available for neuroprognosis over the hemisphere with DC. We aim to determine the degree to which SSEP amplitudes are increased in the absence of cranial bone. This will serve as a precursor for translation to clinically prognostic ranges...

Background: Multidirectional cranial distraction osteogenesis (MCDO) is a procedure of ours developed earlier for treating craniosynostosis. However, the numerous bone flaps led to prolonged operative time and occasional bone detachment from dura. We have since simplified the osteotomy design. In treating sagittal synostosis, required bone flaps have been reduced to 11 (from ~20). Methods: In a 2-year period (2014-2015), 5 boys with sagittal synostosis underwent MCDO using our simplified and fixed-form osteotomy...

Background: Surgical delay remains a common method for improving flap survival. However, the optimal surgical technique has not been determined. In this article, we compare flap perfusion, viable surface area, and flap contraction of 2 surgical delay techniques. Methods: Male Sprague-Dawley rats were divided into 3 groups. In the incisional surgical delay group (n = 9), a 9 × 3 cm dorsal flap was incised on 3 sides without undermining, leaving a cranial pedicle...

Three dogs (Boxer, Labrador Retriever and German Shepherd) between the age of 7-10 years were presented with the history of tumour masses on right caudo-lateral thigh, right cranial forearm and left cranial and caudal thoracic mammary gland region, respectively. Fine needle aspiration cytology of the tumour masses and the sentinel regional lymph nodes were done. Plain radiography was done to rule out distant metastasis. In all the three cases the tumour masses were large in size, firmly adherent to the tissues underneath and sufficient loose skin was not available to close the skin defect following surgery...

We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired...

We present a case of post-traumatic hematoma developing between the 2 layers of the cranial dura in a 2-year-old child following head injury. This child presented with history of fall from a height in altered sensorium with paucity of movements on the left side. Computerized tomography scan of the brain showed a right parietal linear fracture with an underlying hyperdense biconvex hematoma. Emergency evacuation of the hematoma was done. On elevation of the scalp flap, a fibrous membrane was seen protruding between the fracture lines...

REVIEW
Demetri Arnaoutakis, Sameep Kadakia, Manoj Abraham, Thomas Lee, Yadranko Ducic
The goals of reconstruction following any oncologic extirpation are preservation of function, restoration of cosmesis, and avoidance of morbidity. Anatomically, the lateral skull base is complex and conceptually intricate due to its three-dimensional morphology. The temporal bone articulates with five other cranial bones and forms many sutures and foramina through which pass critical neural and vascular structures. Remnant defects following resection of lateral skull base tumors are often not amenable to primary closure...

BACKGROUND: Modern breast reconstruction often involves microvascular reconstruction. The most common recipient vessels are the internal mammary artery and vein. Recently, there has been great focus on efficiency, but much of this emphasis has been directed to faster flap harvest or recovery protocols for expeditious discharge. An equally important aspect is internal mammary vessel preparation. METHODS: Breast reconstruction was performed in 415 patients (715 breasts) using autologous tissue (850 flaps) from 2012 to 2016...
