Purpose: To examine the effects of intrapolyp triamcinolone acetonide (TA) injections on intraocular pressure (IOP) and recurrence of nasal polyps after endoscopic sinus surgery.

Patients And Methods: This was a prospective, randomized, double-blind, placebo-controlled study. Patients were randomized into either the TA injection group (Group I, 20 mg/ml, 2 mL) or the placebo normal saline injection group (group II, 2 mL).

Objectives: In general, deviation of the L-strut of the nasal septum is more challenging to correct than the middle and has less favorable results. This study aimed to develop a technique to correct the L-strut while preserving nasal support effectively and introduce the L-septoplasty technique and its effects.

Methods: Patients with caudal and high dorsal septal deviations who underwent the L-septoplasty technique were retrospectively analyzed.

In surgical repair of orbital fracture, implant materials play an important role in restoring the functional and anatomic structure of the orbit. Alloplastic implant materials are widely used for this surgery, but they have the risk of complications such as infections, pain, and extrusion. Because they are artificial implants, infection can occur more than autologous implants and is the most challenging problem to manage.

Background And Purpose: The aim of this study was to determine how the sleep stage and body position influence the effective pressure (Peff) in standard upward titration and experimental downward titration.

Methods: This study applied successful manual titration of continuous positive airway pressure over 3 hours [including at least 15 min in supine rapid eye movement (REM) sleep] followed by consecutive downward titration for at least 1 hour to 22 patients with moderate-to-severe obstructive sleep apnea. We analyzed baseline polysomnography variables and compared the effective pressures (Peff1 and Peff2) between non-REM and REM sleep and between supine and lateral positions using the paired t-test or Wilcoxon signed-rank test.

Objectives: To (1) compare the radiation dose of low-dose computed tomography (CT) to that of standard-dose CT, (2) determine the minimum optimal radiation dose for use in patients who need endoscopic sinus surgery, and (3) assess the reliability of iterative model reconstruction.

Study Design: Prospective single-institution study.

Setting: Tertiary care center.

Objectives/hypothesis: To investigate the relationship between sleep-disordered breathing (SDB) and nocturnal enuresis (NE) in children and to prospectively evaluate the effectiveness of adenotonsillectomy on resolving enuresis in indicated SDB patients with NE.

Methods: We prospectively collected data from 183 children (121 males, mean age 8.17 ± 2.

Background/objective: There have been several operative techniques for adenoidectomy and their efficacy and morbidity are different according to the technique. This prospective multicenter study was aimed to compare the efficacy and morbidity of coblation adenoidectomy (CA) with those of power-assisted adenoidectomy.

Study Design: Prospective multi-institutional study.

The infraorbital nerve is the largest cutaneous branch of the maxillary divisions of the trigeminal nerve. It may produce a bony ridge on the antral roof but usually goes through within the maxillary bone as a discrete canal. Rarely, it could be partially or completely dehiscent, lying submucosally on the antral roof as in this case.

Objectives: Glucocorticoids, such as dexamethasone (DEX), increase apoptosis in a variety of white cells in nasal polyps and apoptosis is an important factor in the resolution of inflammation. However, the mechanism of glucocorticoids induced apoptosis in nasal polyp remains unclear. In this study the authors evaluated which pathways were engaged in apoptosis induced by DEX in an ex vivo model of nasal polyps.

Orbital fractures are frequently observed in maxillofacial trauma and can cause a wide range of functional impairments and esthetic deformities. Many approaches have been used for the repair of medial orbital wall fractures. It has been necessary to use grafts or splints in these approaches.

Conclusion: Even though the use of TachoComb does not decrease pain after tonsillectomy, it is safe and useful to reduce bleeding after tonsillectomy.

Objectives: Sealing the post-tonsillectomy wound would be expected to reduce pain and bleeding by decreasing the exposure of the traumatized tissue and sensory nerves. TachoComb is a powerful topical hemostatic agent.
