Air pollution exposure and head and neck cancer incidence.

To investigate air pollution's effect in the form of PM (particulate matter measuring less than 2.5 microns) on head and neck aerodigestive cancer incidence, an epidemiological cohort analysis was performed using data from the Surveillance Epidemiology and End Results national cancer database from the years 2002-2012. The relationship between US county mean PM levels and head and neck cancer (HNC) incidence rates were examined using a linear mixed model.

Total Laryngectomy for Respiratory Complications From Advanced Duchenne Muscular Dystrophy.

Due to respiratory weakness, late-stage Duchenne muscular dystrophy (DMD) patients may suffer from chronic aspiration, which is sometimes treated using tracheostomy. However, definitive laryngectomy has not been described in the literature as an aspiration prevention modality in DMD, especially in patients with contraindications to tracheostomy. A case is presented for a patient with advanced stage Duchenne muscular dystrophy suffering from chronic aspiration pneumonia and excessive oral secretions who became ventilator dependent.

Hemodynamic Changes with 1:1000 Epinephrine on Wrung-Out Pledgets Before and During Sinus Surgery.

Background: Intranasal topical 1:1000 epinephrine has been used safely and effectively for hemostasis during endoscopic sinus surgery (ESS). Prior studies assessing hemodynamic changes after intranasal topical epinephrine application have only used soaking wet cottonoid pledgets, and have only assessed for hemodynamic changes before any surgery being performed.

Objective: The purposes of this study were to determine whether intranasal application of topical 1:1000 epinephrine with wrung-out cottonoid pledgets caused significant hemodynamic changes both before and during ESS, and whether it allowed for adequate hemostasis.

Surgical Adjuncts to Rhinoplasty: An Algorithmic Approach.

Background: Nasal aesthetics can be significantly affected by the interdependence of the surrounding bone and soft tissues of the face. These include the maxilla, septum, frontal bone, mandible, and the soft tissues and cartilage surrounding the nose. Therefore, it is pertinent to analyze and address these critical relationships of the nose in order to achieve a successful rhinoplasty.
