Per-nasal Dacryocystostomy

Recovery room oxygenation: a comparison of nasal catheters and 40 per cent oxygen masks.

One hundred and sixty-one ASA physical status I-III patients undergoing elective surgery were evaluated using nasal catheters versus 40 per cent O2 venturi masks. Twenty-one per cent of the patients arrived in the recovery room with hypoxia as measured with a pulse oximeter (SaO2 less than 90 per cent). Fifteen minutes later all patients who arrived hypoxic were well oxygenated on their chosen ...

Nasal Hump Reduction may Improve Dorsal Nasal (Rintala) Flap

  Introduction: Skin defect reconstruction following tumor resection, is a challenge for surgeons. Nose as a key point of aesthetics has a significant role in this scenario. One of the practical approaches is dorsal nasal flap (Rintala) to cover lower 1/3 nasal defects. The disadvantages of this method are limitation to reach lower areas, especially nose tip, flap ischemia and wound dehiscence....

Inflammatory Septal Nasal Polyp

Introduction: Nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. Though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma.  Aetiology is multifactorial and is mainl...

Achieving per-flow Queueing Performance without a per-flow Queue

Recent studies have shown that suitably-designed packet discard policies can dramatically improve the performance of fair queueing mechanisms in internet routers. The Queue State Deficit Round Robin algorithm (QSDRR) preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher throughput and much b...
