Abstract   Background: Over the past 20 years, the minimally invasive endoscopic approach   has gained widespread acceptance. The study was performed to evaluate the   diagnostic method and the success rate of endoscopically diagnosed and treated CSF   rhinorrhea, and also investigations such as leakage site and etiologic factor.   Methods: This retrospective CSF leakage management review of ...

BACKGROUND Infantile cortical hyperostosis is characterised by hyperirritability, acute inflammation of soft tissue, and profound alterations of the shape and structure of the underlying bones, particularly the long bones, mandible, clavicles, or ribs. CASE PRESENTATION We report on a clinical case of a 3-months-old baby girl of non-consanguineous parents. Multiple long bone swellings were th...

OBJECTIVES Expansion of the clinical indications for ablative endoscopic endonasal approaches has behooved us to search for new reconstruction alternatives. We present the anatomic foundations of a novel anterior pedicled lateral wall flap (Hadad-Bassagaisteguy 2 or HB2 flap) for the vascularized reconstruction of anterior skull base defects. STUDY DESIGN Anatomic description. Feasibility stu...

BACKGROUND Congenital skull base defects have traditionally been treated via an intracranial approach. Recent advances in endoscopic management have made minimally invasive extracranial approaches feasible, with less morbidity. OBJECTIVE To determine the success of endoscopic treatment of congenital cerebrospinal fluid leaks and encephaloceles. MAIN OUTCOME MEASURES Retrospective review of ...

Purpose: Assessment of the efficacy of nasoseptal vascularized flap (NSF) in reconstructing the skull base defects after transsphenoidal procedures and CSF rhinorrhea. Material and Methods: Thirteen patients with intraoperative diagnosis of skull base defects and/or CSF leak after endoscopic transsphenoidal surgery or preoperative diagnosis of CSF rrhinorhea were included in this study. Multila...

OBJECTIVE To present our method for anterior skull base reconstruction after oncological resections. METHODS One hundred nine patients who had undergone 120 anterior skull base resections of tumors (52 malignant [43%], 68 benign [57%]) via the subcranial approach were studied. Limited dural defects were closed primarily or reconstructed using a temporalis fascia. Large anterior skull base def...

the clivus is the surface of a portion of the occipital and sphenoid bones in the base of the skull. (1)it is surrounded by the neurovascular structures of the brainstem, as well as internal carotid arteries. tumors of the clivus can be benign (chordoma)or malignant (chondrosarcoma).(2) chordomas are rare, aggressive, slow-growing, invasive, and locally destructive tumors that arise from the no...

ollier’s syndrome, a variant of multiple enchondromatosis, is a rare disease with an estimated prevalence of 1/100,000, characterized by multiple enchondromas, asymmetrically involving small bones of the hands and feet, especially the proximal phalanges. intracranial enchondromas, such as those arising from the skull base are extremely rare. herein, we report a 25-year-old female, known case of...
