To approach Juvenile nasopharyngeal angiofibroma extending to the sphenoid sinus, pterygoid wedge and minimal involvement of the pterygopalatine fossa (Radkowski Stage 2 A) with an endoscopic technique without embolization with no recurrence and minimal morbidity and mortality. This is a retrospective, descriptive study based on the medical records of 15(More)
The extracranial occurrence of meningioma, which is a tumour of the central nervous system, is rare. Two cases of primary extracranial meningioma of the psammomatous variant are reported here. Both cases were managed successfully by endoscopic endonasal approach. Literature has been reviewed and their clinicopathological features are described.
Endoscopic endonasal transorbital approach has been described for the removal of orbital lesions located anteromedially in temporal fossa. The same has been observed to be a versatile approach to the anterior and middle cranial fossa only in laboratory studies. This is the first clinical report of combined transorbital transnasal endoscopic approach to the(More)
Endoscopic endonasal approaches are becoming increasingly popular over transcranial approaches for repair of cerebrospinal leak defects. Sphenoid sinus CSF leaks pose a significant challenge and carry the risk of life-threatening intracranial complications. Their management depends upon identifying the leak using imaging techniques followed by(More)
BACKGROUND Juvenile nasal angiofibromas (JNA) is a benign lesion with high vascularity and propensity of bone erosion leading to skull base invasion and intracranial extension. It is known to involve multiple compartments, which are often surgically difficult to access. With evolution in surgical expertise and technical innovations, endoscopic and(More)
Imaging plays an important role in the diagnosis, staging and prognosis of JNA. Certain radiological changes as seen on CECT were observed to be consistent in our case series. This study analysed preoperative and postoperative CECT of large series of JNA patients to evaluate the sites and pattern of spread of tumor. We evaluated the clinical significance of(More)
OBJECTIVE This paper presents modifications to powered endoscopic dacryocystorhinostomy without stenting for the management of acquired nasolacrimal duct obstruction. STUDY DESIGN A retrospective, non-randomised review. METHOD A total of 105 patients with epiphora secondary to acquired nasolacrimal duct obstruction were operated on by our modified(More)
BACKGROUND Lacrimal sac tumors are very rare and are often missed because patients present with features consistent with chronic dacryocystitis. Squamous cell carcinoma is the common-est lacrimal sac malignancy. Although primary mucoepidermoid carcinomas of the lacrimal sac are rare, they are locally aggressive. Furthermore, their proximity to vital(More)
Juvenile nasopharyngeal angiofibroma is a locally aggressive benign tumour which has propensity to erode the skull base. The tumour spreads along the pathways of least resistance and is in close proximity to the extracranial part of trigeminal nerve. Advancements in expanded approaches for endoscopic excision of tumours in infratemporal fossa and(More)
