A retrospective review of 88 cases of foreign body aspiration was undertaken. The patients ranged in age from 5 months to 73 years; the peak incidences of foreign body aspiration occurred in children less than 3 years of age and in adults older than 50 years. Sixty-one of the 88 patients were male. Physical examination was abnormal in 61% of patients. The most common radiographic abnormality was inspiratory-expiratory abnormality, seen in 27% of patients. Rigid endoscopy under general anesthesia was the preferred method for removal of the aspirated material. Multiple foreign bodies were found in 5% of the patients. Tracheobronchial foreign bodies should, therefore, be strongly suspected in susceptible patient populations who present with a suggestive history, even when no physical or radiographic evidence can be seen. Patients should be carefully examined for multiple foreign bodies at the time of rigid endoscopic removal.

\s=b\Over the years, depression of the malar eminence has been one of the most persistent complications of zygoma fractures, regardless of the fixation technique used. The use of a sublabial incision for direct visualization and alignment of the fracture lines at the infraorbital rim and lateral maxillary buttress is described. When coupled with single miniplate fixation of the zygoma across the frontozygomatic suture, the sublabial approach results in improved reduction of the fractures with rigid stabilization. Our experience with this approach, as well as with two-point wire fixation and with miniplate fixation without sublabial exposure, is reviewed. (Arch Otolaryngol Head Neck Surg. 1989;115:961-963) The zygoma is the principal buttress between the cranium and the maxilla.1·2 It is similar to a four-sided pyramid, with one side of the pyramid forming an articulation with one of four bones-the frontal, the sphenoid, the temporal, and the maxilla.

The molecules, which possess an essentially planar azobenzene skeleton, occupy centers of symmetry of the space group. The conformation of the molecule is such that N(8′) of the azo function is oriented anti with respect to C(1) of the benzene ring.
