In office sampling of eosinophil peroxidase to diagnose eosinophilic chronic rhinosinusitis.

Background: Practical biomarkers for endotypic characterization of chronic rhinosinusitis (CRS) remain elusive, hindering clinical utility. Eosinophil peroxidase (EPX) is an enzyme released by activated eosinophils. The objective of this study was to evaluate a clinic EPX assay as a marker of eosinophilic CRS.

Patient Use of Low-cost Digital Videoscopes and Smartphones for Remote Ear and Oropharyngeal Examinations.

Importance: During the novel coronavirus disease 2019 pandemic, telehealth has become a vital component of health care delivery. For otolaryngology evaluations, examination of the ear and oropharynx is important but difficult to achieve remotely.

Objective: To assess the feasibility of patient use of low-cost digital videoscopes and smartphones for examination of the ear and oropharynx.

Quality of Life Changes Following Concurrent Septoplasty and/or Inferior Turbinoplasty During Endoscopic Pituitary Surgery.

Objective: Endoscopic endonasal transsphenoidal surgery (EETS) is a widely accepted technique for sellar tumors. Common findings during preoperative assessment include septal deviations and turbinate hypertrophy. This study evaluated quality of life changes after concurrent septoplasty and/or inferior turbinoplasty during EETS.

Transnasal endoscopic medial maxillary sinus wall transposition with preservation of structures.

Objectives/hypothesis: To evaluate the increase in access to the maxillary sinus (MS) with transnasal endoscopic medial maxillary sinus wall transposition (TEMMT), while preserving major structures of the nasal cavity.

Study Design: The study was divided into three parts: anatomical, radiographic, and case series.

Methods: Three cadaveric dissections (total of six sides) confirmed the feasibility of the TEMMT approach.

Endoscopic endonasal greater palatine artery cauterization at the incisive foramen for control of anterior epistaxis.

Objectives/hypothesis: To describe the anatomy of the incisive foramen and the transnasal endoscopic approach to the greater palatine artery at this foramen, and to evaluate the importance of the greater palatine artery as a cause of recurrent anterior epistaxis.

Study Design: Anatomical dissection, radiographic study, and prospective case series.

Setting: Academic Medical Center.

Split-calvarial osteopericranial flap for reconstruction following endoscopic anterior resection of cranial base.

Objectives/hypothesis: To conceive and critically evaluate an adaptation of the split calvarial osteopericranial flap for reconstruction following endoscopic endonasal resection of the anterior skull base.

Study Design: Cadaveric anatomic study.

Methods: Five cadavers were embalmed with methanol, and vasculature was injected with latex.

Impact of 13-valent pneumococcal conjugate vaccine on otitis media bacteriology.

Objectives: To determine the microbiology of otitis media (OM) since the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in February 2010.

Methods: Middle ear effusion from a pediatric Otolaryngology population undergoing pressure equalization tube (PET) placement was obtained and sent for aerobic culture and antibiotic susceptibility testing between August 2012 and April 2013. Vaccination records were obtained and statistical analysis was completed.

Current analysis of women athletes with pelvic pain.

Background And Methods: Accurate diagnosis and effective management of pelvic pain in women have become more challenging now that the number of women athletes and the number of diagnostic possibilities are increasing. We conducted a prospective study of women athletes with pelvic pain seen during a 2-yr period within a large well-defined clinical practice to clarify some of the current causes and treatment possibilities.

Results: One hundred fourteen females, 14% of the total male/female cohort, were referred for treatment of suspected musculoskeletal injury.
