Rhinoplasty is one of the most demanding of all cosmetic procedures. The surgeon has to have a knowledge of facial and nasal esthetics and must work within the framework of the structure of the nose at hand. The total preoperative evaluation of the patient is discussed including the process of consultation and recognition of risk factors. The guidelines that we use to structure our esthetically pleasing nose are discussed.
Animal studies indicate that diazepam suppresses resting activity in the vestibular system. Despite lack of clinical studies, diazepam and lorazepam have been used empirically for relief of vertigo. However, drug use with benign paroxysmal vertigo (BPV) is controversial which led to this study to evaluate the value of diazepam and lorazepam for relief of BPV. Twenty-five BPV patients were given diazepam, lorazepam, or a placebo over four weeks using a double-blind technique. Each patient rated his dizziness after each week, and the patient's nystagmus was rated before and after treatment. The result showed a gradual decline in symptoms in all treatment groups with no additional relief with the drugs. The latter was attributed to the fact that BPV represents a dynamic state whereas diazepam provides symptom relief due to action on the system in its static state.
