Botolinum toxin in rhinitis: Literature review and posterior nasal injection in allergic rhinitis.

Background: Current pharmacological management of allergic rhinitis (AR) varies in onset, duration, symptom control, and requires frequent administration. Single-dose botulinum toxin (BTX) has been documented in various trials as a treatment option in rhinitis.

Objective: We review the current literature on the use of BTX in rhinitis and investigate the efficacy and safety profile of a novel intranasal injection site for AR control.

Pre-operative high resolution computed tomography scans for cholesteatoma: has anything changed?

Objective: CT temporal bone scans are often performed to aid in surgical planning and management of cholesteatomas. With improvements in the resolution of CT scans today, it is now possible to obtain more information from these scans than before. The aim of this study is to compare findings on high resolution CT (HRCT) temporal bone scans to intra-operative findings, so as to determine how well various middle ear structures are assessed by HRCT scanning.

Correlating voice handicap index and quantitative videostroboscopy following injection laryngoplasty for unilateral vocal paralysis.

Objective: 1) Determine the correlation between voice handicap index and quantitative videostroboscopy for patients undergoing injection laryngoplasty for unilateral vocal paralysis; 2) assess which videostroboscopy measurements correlate best with voice handicap index in patients demonstrating progressive improvement beyond six months following injection laryngoplasty.

Study Design: Case series with chart review.

Setting: Patients undergoing outpatient injection laryngoplasty with hyaluronic acid between 2005 and 2007.
