Primary Intraosseous Granular Cell Tumor of the Sphenoid and Central Skull Base in a Pediatric Patient.

Background: Granular cell tumors occur in all ages and many anatomic sites. In the craniofacial region, they typically arise in soft tissue, not bone. We present a primary intra-osseous granular cell tumor of the sphenoid and central skull base arising in a 12- year- old girl.

Comparison of Pediatric Otolaryngology clinical and operative case volume among surgical specialties in the COVID-19 pandemic.

Objectives: To report changes in clinical and surgical volume impacting a Pediatric Otolaryngology division one year prior to and following the onset of the COVID-19 pandemic in comparison to five other pediatric surgical subspecialties.

Methods: The number of clinical visits and surgical cases per month for six pediatric surgical specialties (Otolaryngology, Orthopedic Surgery, Urology, Neurosurgery, Plastic Surgery, and General Surgery) for 12 months prior to the pandemic and 12 months following the onset of the pandemic was collected. Poisson regression analysis was performed for the number of visits and cases per season adjusting for specialty, season, staffing changes, and the pandemic to determine adjusted rate ratios (aRR) post-pandemic for the surgical fields compared to Otolaryngology.

The otolaryngologic manifestations in children with eosinophilic esophagitis.

Objectives: (1) To describe the incidence of eosinophilic esophagitis (EoE) in the population of patients undergoing esophagoscopy with biopsy by a pediatric otolaryngology service. (2) To elucidate the demographics, presenting symptoms, and endoscopic findings in children with EoE.

Design: Case series.

Appropriate hearing screening in the pediatric patient with head trauma.

Purpose: To develop an algorithm for the appropriate audiologic screening of in children with head trauma.

Methods: Participants were the first consecutive 50 children admitted to a children's hospital trauma service after October 1, 2005, whose injuries resulted in a Glasgow Coma Scale (GCS) score ≤13 and/or loss of consciousness (LOC) but no history of hearing loss. Screening tympanometry, otoacoustic emissions testing, and/or routine audiometric evaluation were performed as soon as possible after admission.

Repair of the tympanic membrane with urinary bladder matrix.

Objectives/hypothesis: To test urinary bladder matrix (UBM) as a potential treatment for tympanic membrane (TM) healing and regeneration.

Study Design: This prospective pilot study was designed to provide both qualitative and semiquantitative assessment of temporal and spatial healing events in the chinchilla model of chronic TM perforations with and without UBM patching.

Methods: Bilateral myringotomies were performed and repeated as necessary to create subtotal perforations over an 8-week period.

Fourth branchial cleft sinus: relationship to superior and recurrent laryngeal nerves.

Objectives: 1) Demonstrate the surgical anatomy of a fourth branchial cleft sinus relative to the superior and recurrent laryngeal nerves. 2) Review the diagnosis and management of a fourth branchial cleft sinus.

Design: Case Study.

Pediatric myringoplasty: factors that affect success-a retrospective study.

Objective: To evaluate the impact of patient and graft variables on the successful closure of tympanic membrane perforations treated with myringoplasty at the Children's Hospital of Pittsburgh from 2000 to 2005.

Study Design: Retrospective chart review at an academic tertiary-care children's hospital.

Methods: Charts were reviewed for 604 children, ages 1 to 18 years old, with complete records who underwent myringoplasty by the pediatric otolaryngology practice at Children's Hospital of Pittsburgh of UPMC from 2000 to 2005, totaling 777 procedures.

Role of microvascular density in nonlocalizing parathyroid sestamibi scans.

Objectives: Sestamibi scans for localization of abnormal parathyroid glands in patients with hyperparathyroidism are widely used at many institutions. Minimally invasive parathyroid surgery demands accurate preoperative localization imaging; however, nonlocalizing sestamibi scans occur in 15% of patients with primary hyperparathyroidism. It remains unknown why some sestamibi scans fail to localize.
