Nasal obstruction is a highly subjective and commonly reported symptom. The internal nasal valve (INV) is the rate limiting step to nasal airflow. A static INV grading score was devised with regard to visibility of the middle turbinate.
The internal nasal valve (INV) is bound by the nasal septum, inferior turbinate and the upper lateral cartilage (ULC). It is the most important determinant of nasal airflow, and critical for nasal breathing. The normal internal nasal valve angle is 10-15 . Even a small change in the INV angle can have a significant impact on nasal airflow. This article is protected by copyright. All rights reserved.
A clinical study was conducted to determine the effect of nasal valve lift treatment using absorbable, polylactic acid, self-retaining cone threads (Silhouette Soft) in patients with nasal valve stenosis. Sixty patients ( = 60) were included in this prospective study which was performed from January 2015 until December 2018, 19 patients dropped out due to noncompliance. Initially, participants were divided into two equal groups. One was treated by nasal valve lift only, the other additionally received t...
Spreader grafts have been shown to improve nasal airway obstruction in patients with nasal valve dysfunction; however, their use has been limited by concerns over their aesthetic penalty of widening the nasal dorsum.
A major limitation of the more widespread application of aortic valve reconstruction is the lack of a common framework for valve assessment that could be used to guide a standardized approach to aortic valve repair, similar to that used in reconstructive mitral valve surgery. Most patients with a regurgitant aortic valve are young and possess a specific subtype of a bicuspid aortic valve according to the Sievers classifications system. This video tutorial presents the technical aspects of a standardized ...
The combination of grading and staging is the basis of current standard of care for prediction for most cancers. D. F. Gleason created the current prostate cancer (PCa) grading system. This system has been modified several times. Molecular data have been added. Currently, all grading systems are cancer-cell based.
OBJECTIVEThe objective of this study was to evaluate the existing Spetzler-Martin (SM), Spetzler-Ponce (SP), and Lawton-Young (LY) grading systems for cerebellar arteriovenous malformations (AVMs) and to propose a new grading system to estimate the risks associated with these lesions.METHODSData for patients with cerebellar AVMs treated microsurgically in two tertiary medical centers were retrospectively reviewed. Data from patients at institution 1 were collected from September 1999 to February 2013, and a...
Previously, our group developed the Parkland Grading Scale for Cholecystitis (PGS) to stratify gallbladder (GB) disease severity that can be determined immediately when performing laparoscopic cholecystectomy (LC). In prior studies, PGS demonstrated excellent interrater reliability and was internally validated as an accurate measure of LC outcomes. Here, we compare PGS against a more complex cholecystitis severity score developed by the national trauma society (AAST), which requires clinical, operative, ima...
To describe prosthetic rehabilitation following partial rhinectomy with use of a novel retentive internal nasal keeper piece.
Transcatheter pulmonary valve replacement (TPVR) is now common practice in patients with significant pulmonary regurgitation (PR), stenosis (PS), or mixed pulmonary valve disease. While the Melody valve (Medtronic, Inc.) and its delivery system were specifically designed for use in the right ventricular outflow tract (RVOT), Sapien valves (XT and S3, Edwards Lifesciences, Inc.) and their delivery systems (Novaflex and Commander) were not. As a result, placement of Sapien valves in the RVOT can be challengin...
OBJECTIVEThe present study aims to assess the clinical utility of a previously validated intraoperative meningioma consistency grading scale and its association with extent of resection (EOR) and various surgical outcomes.METHODSThe previously validated grading system was prospectively assessed in 127 consecutive patients undergoing open craniotomy for meningioma by multiple neurosurgeons at two high-volume academic hospitals from 2013 to 2016. Consistency grading scores ranging from 1 (soft) to 5 (firm/cal...
Transcatheter mitral valve replacement is an emerging technology for the treatment of mitral valve regurgitation. Numerous devices are in development and in various stages of clinical investigation. The Tendyne system (Tendyne Holdings, LLC, a subsidiary of Abbott Vascular, Roseville, Minnesota) is a fully repositionable and retrievable, transapical transcatheter mitral valve replacement platform. The results of the early feasibility studies in the U.S. are highly encouraging and a pivotal randomized trial ...
Congenital nasal cleft is a very rare yet challenging deformity to reconstruct. Atypical craniofacial clefts that involve the nasal ala are designated as number 1 and number 2 under the Tessier classification system. These clefts typically present as notches in the medial one-third of either nasal ala and may be accompanied by a malpositioned cartilaginous framework. Nasal clefts are smaller and far less common than familiar clefts of the lip and palate, but they pose equally challenging reconstructive plan...
Confocal laser endomicroscopy (CLE) is a fluorescence-based fiber-optic imaging technique with the potential for intraoperative grading of upper tract urothelial carcinoma (UTUC). This study aims to (1) investigate the prevalence of the previously proposed CLE criteria for bladder cancer in papillary UTUC, (2) estimate the diagnostic value of CLE for UTUC grading and (3) propose a scoring system for a more quantifiable approach of CLE-based grading of UTUC.
The nasal cannula and modified nasal hood are methods used by oral and maxillofacial surgeons to detect expired carbon dioxide during procedural sedation in an open airway system. The purpose of this study was to compare the accuracy of the detection of expired carbon dioxide between the nasal cannula and modified nasal hood.
Valve selection in dialysis-dependent patients can be difficult because long-term survival is diminished and bleeding risks during anticoagulation treatment are greater in patients with renal failure. In this study we analyzed long-term outcomes of dialysis-dependent patients who underwent valve replacement to help guide optimal prosthetic valve type selection.
We aimed to verify the usefulness of our proposed nasal symptom questionnaire (NSQ) scoring system and to determine predictors linked to the improvement in nasal symptoms in chronic rhinosinusitis (CRS) patients undergoing endoscopic sinus surgery (ESS).
A simple, reliable grading scale to better characterize nonfunctioning pituitary adenomas (NFPAs) preoperatively has potential for research and clinical applications.
'Nasal mask' in comparison with 'nasal prongs' or 'rotation of nasal mask with nasal prongs' reduce the incidence of nasal injury in preterm neonates supported on nasal continuous positive airway pressure (nCPAP): A randomized controlled trial.
With increasing use of nCPAP, the safety and comfort associated with nCPAP have come into the forefront. The reported incidence of nasal injuries associated with the use of nCPAP is 20% to 60%. A recent meta-analysis concluded that the use of nasal masks significantly decreases CPAP failure and the incidence of moderate to severe nasal injury and stress the need for a well powered RCT to confirm their findings.
In phytophagous sap-sucking insects, the precibarial valve plays an important role in sap ingestion. We used light and electron microspcopy to study the morphology and the ultrastructure of the precibarial valve of the meadow spittlebug, Philaenus spumarius (Hemiptera, Aphrophoridae), in order to better understand the operative mechanism of this structure. The precibarial valve revealed to be a complex structure with a bell-like invagination in the middle of the precibarium (on the epipharynx). Unlike the c...
There are significant clinical and financial consequences to both inadequate and unnecessary exposure to broad-spectrum antibiotics. As such, antimicrobial stewardship programs seek objective, reliable, and cost-effective tests to identify patients at highest or lowest risk for drug-resistant organisms to guide empiric antimicrobial selection. Utilization of methicillin-resistant Staphylococcus aureus (MRSA) nasal screening to rule out MRSA in lower respiratory tract infections has led to significant reduct...
The DEDICATE Trial: An independent all-comers trial of transcatheter aortic valve implantation vs. surgical aortic valve replacement in patients at low to intermediate operative risk is recruiting patients.
We present a simpler and faster way of implanting the Edwards Intuity Elite rapid deployment valve system. Annular sizing and guiding suture placement are performed in the usual manner. After the valve is parachuted down to the annulus, the balloon catheter is detached and a vent catheter is placed through the center hole to maximize exposure of the valve. The guiding sutures are tied down using an automated suture fastening device instead of securing snares. Visualization of the tip of the suture fastener ...
