Randomized Controlled Trial
The effects of sevoflurane and isoflurane in nasal septal surgery.
The objective of this study was to evaluate the effect of sevoflurane and isoflurane in nasal septal surgery in terms of intraoperative blood loss, operation time, recovery time, and especially postoperative pain. ⋯ Sevoflurane, which is one of the volatile anesthetics, leads to a lower amount of intraoperative bleeding, postoperative pain, and operation time than isoflurane during nasal septal surgery.

A zygomaticomaxillary complex fracture is a facial bone fracture that commonly occurs as a centrally and laterally protruding zygomatic area. The exact reduction of the displaced fracture is the most important task in the treatment of a zygomatic fracture, from the aesthetic point of view. In some types of zygomaticomaxillary complex fracture, however, it is somewhat difficult to maintain the reduction after the surgery using 3-point fixation. In addition, surgery using 3-point fixation may cause malunion or nonunion. Thus, 4-point fixation using the coronal approach is alternatively considered. The authors performed 4-point fixation using the preauricular approach to counter the disadvantages of the coronal approach. The results and usefulness of 4-point fixation using the preauricular approach are reported in this study. ⋯ Exact reduction and internal fixation of a fracture site are required to restore the appearance and functions of the normal face and to reduce complications such as malunion or nonunion in patients with a zygomaticomaxillary complex fracture. If a complex fracture of the zygomatic body or facture of the zygomaticomaxillary buttress is accompanied by a fracture of the inferior orbital rim, and thus, if incomplete reduction or malunion is anticipated, 4-point fixation using the easier-to-manipulate preauricular approach would be more useful than the conventional method that uses the coronal approach.
