The extended transsphenoidal approach is a less invasive method for removing purely suprasellar lesions compared with traditional transcranial approaches. Most advocates have used sublabial incision and microscope reported significant risk of cerebrospinal fluid (CSF) leakage. authors report on series endoscopic endonasal surgeries resection supradiaphragmatic above normal-sized sella turcica low CSF leakage.A was to remove in 10 patients. Five were prechiasmal (three tuberculum sellae two...
OBJECTIVE Transnasal endoscopic cranial base surgery is a novel minimal-access method for reaching the midline base. Postoperative cerebrospinal fluid leak remains persistent challenge. A new watertight closure of anterior presented. METHODS To achieve base, autologous fascia lata was used to create "gasket seal" around bone buttress, followed by application tissue sealant such as DuraSeal (Confluent Surgical, Inc., Waltham, MA). The gasket-seal seal in series 10 patients with intradural...
Endoscopic cranial base surgery is a minimal access, maximally aggressive alternative to traditional transfacial, transcranial, or combined open approaches. Previous descriptions of endoscopic approaches have used varying terminology, which can be confusing the new practitioner. Indications for are not well defined. Our objective was create comprehensive classification system various and describe their indications with case examples.We prospectively compiled database our endonasal...
Abstract Objectives/Hypothesis: Eustachian tube dysfunction (ETD) is a common condition that associated with otologic and rhinologic symptoms. The complete assessment of ETD limited without valid symptom score. We developed conducted initial validation the seven‐item Tube Dysfunction Questionnaire (ETDQ‐7), disease‐specific instrument to assess symptoms respect ETD. Study Design: Validation study. Methods: ETDQ‐7 was using standard survey methodology. completed by group 50 consecutive adult...
BACKGROUND The endoscopic, endonasal, extended transsphenoidal approach is a minimal-access technique for managing craniopharyngiomas. Outcome measures such as return to employment and body mass index (BMI) have not been reported are necessary comparison with open transcranial approaches. Most prior reports of the endonasal unacceptably high cerebrospinal fluid (CSF) leak rates. OBJECTIVE To assess outcome surgery in consecutive series craniopharyngiomas special attention extent resection,...
Intraoperative identification of cerebrospinal fluid (CSF) leakage is critical in successful closure after endoscopic cranial base surgery. Intrathecal injection fluorescein quite useful identifying CSF leaks. However, complications have been reported with various doses and the technique has fallen out favor. We explored safety low-dose intrathecal administered to patients undergoing A retrospective chart review postoperative patient survey were performed. The nature incidence subjective...
In this paper the authors' goal was to present their clinical experience with lesions of pterygopalatine fossa, infratemporal lateral sphenoid sinus, cavernous petrous apex, and Meckel cave using simple extended endoscopic transpterygoid approaches skull base.Simple expanded were performed in a series 13 patients varying pathology that included sinus encephaloceles, benign malignant sinonasal tumors, neural origin.A gross-total resection achieved 5 9 patients, while subtotal for tissue...
We describe a novel 3-dimensional (3-D) stereoendoscope and discuss our early experience using it to provide improved depth perception during transsphenoidal pituitary surgery.Thirteen patients underwent endonasal endoscopic surgery. A 6.5-, 4.9-, or 4.0-mm, 0- 30-degree rigid 3-D (Visionsense, Ltd., Petach Tikva, Israel) was used in all cases. The endoscope is based on "compound eye" technology, incorporating microarray of lenses. Patients were followed prospectively compared with matched...
OBJECTIVE Planum sphenoidale (PS) and tuberculum sellae (TS) meningiomas cause visual symptoms due to compression of the optic chiasm. The treatment choice is surgical removal with goal improving vision achieving complete tumor removal. Two options exist remove these tumors: transcranial approach (TCA) endonasal endoscopic (EEA). Significant controversy exists regarding which provides best results whether there a subset patients for whom an EEA may be more suitable. Comparisons using similar...
Objectives/Hypothesis To assess balloon dilation of the Eustachian tube with catheter in conjunction medical management as treatment for dilatory dysfunction. Study Design In this prospective, multicenter, randomized, controlled trial, we assigned, a 2:1 ratio, patients age 22 years and older dysfunction refractory to therapy undergo or alone. Methods The primary endpoint was normalization tympanogram at 6 weeks. Additional endpoints were Tube Dysfunction Questionaire‐7 symptom scores,...
Large dural defects after extended endoscopic endonasal skull base resections require meticulous reconstruction to prevent a cerebrospinal fluid leak postoperatively. The nasoseptal flap is vascularized tissue graft developed aid in the multilayer of base. purpose this study describe first experiences with bilateral flaps for very large defects.Prospective, observational study.Large tertiary referral center (New York Presbyterian Hospital).Five patients underwent an transsphenoidal surgery...
Object The purpose of this study was to analyze preoperative predictors endocrinological remission following endonasal endoscopic resection therapy-resistant prolactin-, growth hormone (GH)–, and adrenocorticotropic (ACTH)–secreting pituitary adenomas establish benchmarks for cure by using the most recent consensus criteria. Methods authors reviewed a prospective database 86 consecutive functional that were resected purely transsphenoidal technique. Extent evaluated on postoperative...
OBJECT Although the endonasal endoscopic approach has been applied to remove olfactory groove meningiomas, controversy exists regarding efficacy and safety of this compared with more traditional transcranial approaches. The was supraorbital (eyebrow) keyhole technique, as well a combined “above-and-below” approach, evaluate relative merits each in different situations. METHODS Nineteen cases were reviewed divided according operative technique into 3 groups: purely (6 cases); eyebrow...
