Bioabsorbable steroid-releasing implants in the frontal sinus ostia: a pooled analysis.

Background: Bioabsorbable steroid-releasing implants (mometasone furoate, 370 μg) are effective for improving postsurgical outcomes in the frontal sinus ostia (FSO). In this study we evaluated the effect of these implants on frontal outcomes in various patient subgroups with chronic rhinosinusitis (CRS) using pooled data from 2 randomized, controlled trials (RCTs).

Methods: A total of 160 subjects were enrolled in 2 RCTs.

Safety, feasibility, and efficacy of placement of steroid-eluting bioabsorbable sinus implants in the office setting: a prospective case series.

Background: The outcomes of endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) can be compromised by postoperative inflammation, recurrent polyposis, middle turbinate lateralization, and synechiae, often requiring subsequent interventions. A bioabsorbable steroid-eluting sinus implant placed in the operating room following ESS has been proven safe and effective in 2 randomized controlled trials and a subsequent meta-analysis, for its ability to preserve sinus patency, and reduce medical and surgical interventions. This trial sought to evaluate the safety, feasibility, and outcomes of implants placed in the office after achieving hemostasis.

Self-cross-linked hyaluronic acid hydrogel in ethmoidectomy: a randomized, controlled trial.

Background: This study was designed to evaluate the safety and efficacy of a novel, self-cross-linked hyaluronic acid (HA) hydrogel compared with carboxymethylcellulose (CMC) viscous foam in promoting healing when applied after ethmoidectomy. A prospective, randomized, controlled, blinded clinical trial was performed. The study was performed by four surgeons operating in two community hospitals.

Determinants of outcomes of sinus surgery: a multi-institutional prospective cohort study.

Objectives: 1) To measure the proportion of patients with chronic rhinosinusitis (CRS) who experience clinically significant improvement after endoscopic sinus surgery (ESS) in a prospective, multi-institutional fashion. 2) To identify preoperative characteristics that predict clinically significant improvement in quality of life (QOL) after ESS.

Study Design: Prospective, multi-institutional cohort study.

Image-guided frontal trephination: a minimally invasive approach for hard-to-reach frontal sinus disease.

Objectives: Peripherally located frontal sinus pathology may be unreachable with standard endoscopic techniques. Patients with superiorly or laterally based lesions often undergo osteoplastic flap with or without obliteration. Image-guided frontal trephination (IGFT) can localize pathology and provide excellent exposure.

Intranasal deposition of nebulized saline: a radionuclide distribution study.

Background: Despite the popularity of various nasal sprays and nebulizers, there are limited data regarding the anatomic distribution of particles generated by these devices. This pilot study sought to characterize distribution patterns of nebulized and sprayed saline particles in normal subjects and postsurgical sinus patients.

Methods: Fifteen subjects were studied in three trials: metered-dose nasal spray bottle versus vortex-propelled nebulizer in normal subjects, passive-diffusion nebulizer versus vortex nebulizer in normal subjects, and passive nebulizer versus vortex nebulizer in postsurgical sinus patients.

The utility of bipolar electrocautery in hereditary hemorrhagic telangiectasia.

Objective: The surgical treatment of epistaxis associated with hereditary hemorrhagic telangiectasia (HHT) is varied. Laser therapy is often inadequate for larger complex lesions. This study sought to determine if bipolar cautery can be effectively and safely used in treating HHT-associated epistaxis.

Surgical revision of the post-Caldwell-Luc maxillary sinus.

Background: Endoscopic sinus surgeons are commonly faced with the management of patients with persistent maxillary sinusitis despite previous Caldwell-Luc surgery. Given the potential for altered mucociliary clearance in the post-Caldwell-Luc maxillary sinus, the optimal approach for surgical revision has not been well characterized. The objective of this study was to review our experience in endoscopic versus repeat Caldwell-Luc approaches in patients who have failed Caldwell-Luc surgery for chronic maxillary sinusitis.

Surgical revision of the failed obliterated frontal sinus.

Background: Surgical revision of failed frontal sinus obliteration, traditionally, has been limited to repeat obliteration. However, endoscopic techniques may be successful in selected cases. We review our experience in surgical revision of failed frontal obliteration and propose a management algorithm.

Basic anatomy and physiology of olfaction and taste.

The chemical senses of taste and smell are important to survival and quality of life. Both senses rely on the binding of odorant molecules to receptors located on the receptor cells. Olfaction and gustation have complex systems of coding, but they display differing methods for coding the receptor stimulus.

The office management of recalcitrant rhinosinusitis.

The patient referred to the otolaryngologist for the treatment of CRS has received many therapies for the condition. Newer therapies available focus on the anti-inflammatory therapies and local application of antimicrobial and antifungal agents to the sinus cavities. Much clinical work remains to be done to prove the efficacy of currently available treatments.
