[The actual problems in functional and aesthetic nasal surgery].
Functional and aesthetic nasal surgery has been undergoing a process of fine-tuning. The surgical approaches lean toward greater conservation-particularly aesthetic- and functional selectivity. This has been made possible by improved diagnostic methods and pre-operative programming techniques such as computerized morphometry, computerized axial tomography, rhinosinus endoscopy, rhinomanometry, acoustic rhinometry and electromyography. Another important point in functional and aesthetic nasal surgery is that a) it can be divided into different techniques for each anatomo-functional sector considered and b) these can be used together in various combinations. Experience and the literature have underscored some issues which are most pertinent to the modern methodological viewpoint. The first large-scale controversy involves a comparison of open and closed techniques for access. The advantages and disadvantages of both techniques are described, although the disadvantages can be reduced to a minimum if the right indication is chosen. In the authors' opinion, the open technique should be reserved for general revision surgery, particularly in conjunction with difficult tips, labiopalatoschisis reconstruction, septal perforation and saddle nose. The second basic point involves how to deal with the perichondrium-periostium-mucosal flaps. The two main techniques for nasal skeletizing in rhinoseptoplasty include the extra-mucosal approach which is conservative and the trans-mucosal approach which is apparently more traumatic. Curiously, however, it is the latter technique which leads to fewer medium-long term complications. The nasal tip is the crux for the neophyte to rhinoseptoplasty. Through knowledge of the indications and the risks of the various techniques makes it possible to predict the result before-hand, although with certain margin of error. Indeed, this is one of the regions of the nose where errors reap the greatest damage. In this anatomical site, the use of conservative techniques is, therefore, strongly suggested. Finally, not only has research into the field of functional nasal surgery been unable to find concrete applications in humans (for obvious ethical reasons), it has likewise been unable to provide an answer to the question most rhinosurgeons pose: why do some patients still complain of difficulty breathing, even after successful surgery? It is our conviction that the problem is due to the fact that research into the endonasal receptors has not progressed.
