Sudden sensorineural hearing loss in children and adolescents: Clinical characteristics and age-related prognosis.

Objective: Although many studies have investigated sudden sensorineural hearing loss (SSNHL) in adults, there were few studies on SSNHL in the pediatric population; especially research on treatment and prognosis of pediatric SSNHL was limited. The aim of this study was to evaluate clinical characteristics, treatment outcomes and prognostic factors in children and adolescents with SSNHL.

Methods: A retrospective review of medical records of 67 pediatric patients (67 ears) who had diagnosed with SSNHL at our hospitals was performed to analyze patients' clinical manifestations and audiograms.

Characteristics of rib cartilage calcification in Asian patients.

IMPORTANCE Rib cartilage from the sixth, seventh, and eighth ribs offers a long cartilaginous curvature, making the material reliable for grafting. Calcification of cartilage causes unexpected absorption, difficult manipulation, and donor site morbidity. Most studies of calcification were performed in Western countries.

Association between Positional Dependency and Obstruction Site in Obstructive Sleep Apnea Syndrome.

Objectives: The purpose of this study is to find out associations between positional dependency and obstructive levels based on sleep videofluoroscopy (SVF) in patients with obstructive sleep apnea syndrome (OSAS).

Methods: Retrospective review was made of 91 OSAS patients who underwent polysomnography and SVF from August 2009 through June 2010. Polysomnography variables including apnea-hypopnea index (AHI), supine AHI, non-supine AHI, time spent in supine sleep position of the total sleep time and positional dependency (PD) were analyzed.

Tracheal growth after airway stenosis surgery: serial radiographic comparative study.

Conclusion: The proportion of stenotic area over normal tracheal lumen does not decrease over time after airway stenosis surgery regardless of endoscopic or open surgery, which suggests that the operated laryngotracheal complex may grow and develop similarly to the normal surrounding tissue.

Objectives: To evaluate the effect of pediatric airway stenosis surgery on the growth of the laryngotracheal complex and to compare the differences between endoscopic and open surgery.

Methods: Forty-five successful stoma closures after pediatric airway stenosis surgery were performed between 2001 and 2007.

A huge chondromyxoid fibroma of the nasal cavity in a newborn baby.

Chondromyxoid fibroma is a rare benign tumor that usually occurs in the long bones. A 2-month newborn presented with huge masses in the both nasal cavities, which turned out to be chondromyxoid fibroma. The masses originated from both inferior turbinates.
