Abstract
Co-culture of microalgae and microorganisms, supported with the resulting synergistic effects, can be used for wastewater treatment, biomass production, agricultural applications and etc. Therefore, this study aimed to explore the role of Bacillus subtilis (B. subtilis) in tolerance against the harsh environment of seafood wastewater, at which these microalgal-bacterial flocs were formed by microalgae cultivation. In this present study, B. subtilis isolated from the cultivation medium of Chlorella vulgaris and exposed to different salinity (0.1-4% w/v sodium chloride) and various pH range to determine the tolerant ability and biofilm formation. Interestingly, this bacteria strain that isolated from microalgae cultivation medium showed the intense viability in the salt concentration exceeding up to 4% (w/v) NaCl but demonstrated the decrease in cell division as environmental culture undergoing over pH 10. Cell viability was recorded higher than 71% and 92% for B. subtilis inoculum in media with salt concentration greater than 20 gL-1 and external pH 6.5-9, respectively. This showed that B. subtilis isolated from microalgal-bacteria cocultivation exhibited its tolerant ability to survive in the extremely harsh conditions and thus, mitigating the stresses due to salinity and pH.

Abstract
Suture techniques are widely used and can be very useful and efficient to support the nasal tip and correct its deformities. Nevertheless, they are so powerful that they have to be performed very precisely if the surgeon does not want to create cosmetics as well as functional problems. The authors describe the main tip sutures and their effects, expected or not.

Abstract
Osteotomies are performed to modify the shape of the bony part of the nose, therefore they should not be done systematically. Main indications are correction of deviated nose, narrowing of bony vault and roofing of an open roof after important hump resection. The nose should be very precisely analyzed before osteotomies if the surgeon doesn't want to create deformities such as step, inverted V, pinched nose or saddle nose. When too narrowed, bones can also block the airway and lead to functional problems.

Abstract
Secondary rhinoplasty is very usual. Some patients are not satisfied by the previous surgery because the result is poor with obvious defaults but, sometimes, the result is good but the patient expects perfection. These two different situations will not lead to the same answer from the surgeon. Techniques of secondary rhinoplasty are the same than primary, but are often more difficult to perform because of scar tissue, retraction and loss of lining. The authors analyse the more frequent deformities in secondary rhinoplasty and the way they fix them.

Abstract
In the first step of rhinoplasty, the surgical approach will expose through different types of incisions and dissection planes the osteocartilaginous framework of the nasal pyramid prior to performing actions to reduce or increase the latter. This exposure can be performed by a closed approach or by an external approach--the choice depends on the type of nose and the habits of the surgeon. Far from being opposites, closed and external approaches are complementary and should be known and mastered by surgeons performing rhinoplasty.

Abstract
Preoperative analysis in rhinoplasty consists in analyzing individual anatomical and functional characteristics without losing sight of the initial requirements of the patient to which priority should be given. The examination is primarily clinical but it also uses preoperative photographs taken at specific accurate angles. Detecting functional disorders or associated general pathologies, which will reduce the risk of complications. All of these factors taken into account, the surgeon can work out a rhinoplasty plan which he or she will subsequently explain to the patient and obtain his or her approbation.

Abstract
To many surgeons, nasal airway obstruction is synonymous with either septal deviation or inferior turbinate hypertrophy. The role of internal and external nasal valves is often less known by surgeons even if it is crucial in nasal breathing and strongly interrelated with esthetic of the middle third of the nose and alar wall. Therefore, precise examination of the two valves and conservative surgery should help to avoid many functional and esthetic problems.

Abstract
Overprojected tip is a pretty usual request not easy to manage. Preop analysis is crucial in order to evaluate tip support and skin thickness and ability to retract. For example, if the skin is very thick and has poor chance to retract, the surgeon should be very careful in the tip projection decreasing to avoid a skin pollybeak deformity. In such cases, he has to analyze the facial proportions, especially other areas projection (radix, dorsum and chin) and think about augmenting them to balance the profile rather than decreasing tip projection. Correction should always be conducted incrementally, starting with weakening the tip support mechanisms and, only if necessary, continue with alar cartilage interruption. This can be performed on many areas (lateral cruras, domes, medial cruras) and with several techniques (resection or interruption+overlapping).
