Efficacy and Safety of Autologous Stromal Vascular Fraction in the Treatment of Empty Nose Syndrome.

Objectives: Regenerative treatment using stem cells may serve as treatment option for empty nose syndrome (ENS), which is caused by the lack of turbinate tissue and deranged nervous system in the nasal cavity. We aimed to assess the efficacy and safety of the autologous stromal vascular fraction (SVF) in the treatment of ENS.

Methods: In this prospective observational clinical study, we enrolled 10 ENS patients who volunteered to undergo treatment of ENS through the injection of autologous SVF.

Effects of sodium bicarbonate concentration on growth, photosynthesis, and carbonic anhydrase activity of macroalgae Gracilariopsis lemaneiformis, Gracilaria vermiculophylla, and Gracilaria chouae (Gracilariales, Rhodophyta).

There is potential for bicarbonate to improve crop yields and economic efficiency of marine algae. However, few studies have focused on the effect of bicarbonate on the growth, photosynthesis, and enzyme activity associated with carbon utilization, especially in commercial macroalgae. Here, the addition of bicarbonate (up to 420 mg L(-1)) to macroalgal cultures has been evaluated for Gracilariopsis lemaneiformis, Gracilaria vermiculophylla, and Gracilaria chouae with respect to growth rate, photosynthetic activity, carbonic anhydrase activity, and biochemical composition.

Correlation between remnant inferior turbinate volume and symptom severity of empty nose syndrome.

Objectives/hypothesis: Empty nose syndrome (ENS) is an iatrogenic disorder caused by turbinate reduction procedures, which results in considerable nasal dysfunction and severely impaired quality of life. However, there is a lack of data that explains the relationship between the degree of turbinate reduction and subjective symptoms. The aim of this study was to evaluate the effects of remnant inferior turbinate volume on symptom severity.

Aesthetic Motivation of Geriatric Rhinoplasty The Surgical Outcome.

Background: Rhinoplasty in the elderly population has recently emerged as an issue in terms of rejuvenation. There, however, is a paucity of published data on geriatric rhinoplasty in Asian patients. The aims of this study were to investigate the motivation of aged Korean patients to undergo the procedure, and to demonstrate our experience of rhinoplasty in patients of 60 years of age and older.

Influence of middle ear mucosal condition on post-tympanoplasty audiologic outcome.

In this study, the association between the middle ear mucosal condition and post-tympanoplasty audiologic outcome was investigated in patients with chronic otitis media without cholesteatoma. One hundred and forty-three patients with chronic otitis media were collected in the Department of Otorhinolaryngology-Head and Neck Surgery at Asan Medical Center between January, 2009 and December, 2011. In the course of tympanoplasty, the status of the middle ear mucosa was divided into normal or abnormal by one surgeon.

Prognostic value of lymph node density in high-grade salivary gland cancers.

Background: To investigate the role of lymph node density (LND) as an independent prognostic factor in high-grade salivary gland cancers.

Methods: All 87 patients with high-grade salivary gland cancers underwent curative surgery combined with neck dissection and most of them received postoperative radiotherapy or chemoradiotherapy. LND was calculated as the ratio of positive lymph nodes to total lymph nodes harvested.

Clinical values of (18) F-FDG PET/CT in oral cavity cancer with dental artifacts on CT or MRI.

Level Of Evidence: 2a

Background And Objectives: To investigate the role of (18) F-FDG PET/CT in tumor staging, extent, and volume measurements in oral cavity squamous cell carcinoma (OSCC) patients with/without dental artifacts on CT or MRI.

Methods: This study was conducted in 63 consecutive patients with OSCC who received initial workups including (18) F-FDG PET/CT and MRI. The results of the imaging modalities were compared to those of pathology, using McNemar's test and the paired t-test.

Long-term follow-up of otitis media with effusion in children: comparisons between a ventilation tube group and a non-ventilation tube group.

Objective: The objective of this study was to investigate the long-term outcomes in children with otitis media with effusion who received either medical treatment or ventilation tubes.

Methods: We retrospectively analyzed the medical records of 89 bilateral cases of otitis media with effusion in children who were recommended to receive ventilation tube insertion and were followed up for more than 5 years. Tympanic membrane was inspected by otoscopic examination.

Results of caloric and sensory organization testing of dynamic posturography in migrainous vertigo: comparison with Meniere's disease and vestibular neuritis.

Conclusion: Our findings suggest that migrainous vertigo (MV) has a substantial vestibulo-spinal abnormality that can be uncovered by posturography. Patients with MV also showed a difficulty in using multisystem information, especially somatosensory information. Caloric and sensory organization tests (SOTs) have complementary roles in assessing vestibulo-ocular and vestibulo-spinal function, particularly for Meniere's disease (MD) and MV.

The clinical application and efficacy of sodium hyaluronate-carboxymethylcellulose during tympanomastoid surgery.

Objectives/hypothesis: To evaluate the anti-adhesive and anti-inflammatory effects of sodium hyaluronate-carboxymethylcellulose (HA-CMC) on postoperative hearing improvement and complications during tympanomastoid surgery.

Study Design: Prospective controlled clinical trial.

Methods: We evaluated 287 patients who underwent type I tympanoplasty, with or without canal wall up mastoidectomy, between January 2007 and June 2010.
