aesthetic lines after osteotomies, symmetries of the middle third. It is also used for functional recovery of opening the nasal valve. The evaluation of the results of spreader graft is difficult and subjective. Measuring nasal valve angle is an objectie criteria of functional outcome, the brow tip aesthetic lines referred by Tardy and Sheen are options for aesthetic evaluation. Our common indi...

BACKGROUND Nasal obstruction is a common complaint seen by otolaryngologists. The internal nasal valve (INV) is typically the narrowest portion of the nasal cavity, and if this area collapses on inspiration the patient experiences significant symptoms of nasal obstruction. The nasal obstruction is further compounded if the INV is narrower than normal. Previous studies have evaluated the effecti...

BACKGROUND This study compared the effectiveness of a Specially Designed Paste Carrier technique with the Syringe-Spreader technique and the Syringe-Lentulo spiral technique in the intracanal placement of calcium hydroxide. METHODS Three groups, each containing 15 single-rooted human anterior teeth were prepared using standardized Mtwo rotary instruments to a master apical file size 40 with 0...

background nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. this study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. methods fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. objective a...

Experimental evolution studies have investigated adaptive radiation in static liquid microcosms using the environmental bacterium Pseudomonas fluorescens SBW25. In evolving populations a novel adaptive mutant known as the Wrinkly Spreader arises within days having significant fitness advantage over the ancestral strain. A molecular investigation of the Wrinkly Spreader has provided a mechanisti...

PURPOSE To determine the efficacy of INTACS insertion using a femtosecond laser in the treatment of keratoconus and to compare it to the technique using a mechanical spreader. METHODS INTACS were inserted in 10 eyes using the mechanical spreader to create the channels and subsequently on another 20 eyes using the femtosecond laser. Uncorrected (UCVA) and best spectacle-corrected visual acuity...

A study was conducted to compare the efficacy of two methods of obtaining the joint exposure needed to perform arthrodesis or exploration of various joints of the foot. The investigation was performed by means of simulated arthrodesis in a cadaveric model. On each specimen, a single investigator performed standard incisions and dissection as typically performed for surgical arthrodesis of the f...

BACKGROUND Although the assignment and suturing of the spreader graft to the septum is a routine part of rhinoplasty, it is a time wasting procedure and some problems may occur. Rather, autospreader flap is a new method that the dorsal part of the upper lateral cartilage is used as its own graft. In the present study, we intended to compare the functional and aesthetic outcomes of these two ...

There is no specialized equipment designed to spread granular cylindrical organic fertilizer in the soil. are also rational recommendations available on how this type of fertilizer. Mineral spreaders most often used for spreading granulated However, these fertilizers significantly different from mineral fertilizers. Due differences, unevenly, and does not reach required working width. Furthermo...

An analytical model of a spreader-stoker wood waste fired boiler has been developed for pre­ dicting the size of the largest particle which can be entrained by the upward motion of the furnace gases. This model is based on an entrainment model which equates particle in-situ settling velocity to furnace gas velocity and uses a stirred reactor mod­ el to evaluate furnace conditions. The effects o...
