Extended fronto-orbital approaches to the anterior cranial base: variations on a theme.

Combined frontal, orbital and zygomatic osteotomies have expanded the skull base surgeon's repertoire of approaches to the anterior skull base. Techniques borrowed from craniofacial surgery provide for extensive exposure of the orbit and anterior fossa while minimizing brain retraction. This article emphasizes the variations on the theme of fronto-orbital craniotomy that allow this approach to be adapted to the precise location and extent of the lesion to be excised. Familiarity with these versatile techniques is an important part of the skull base surgeon's armamentarium.

Monocortical miniplate fixation of mandibular angle fractures.

Noncompression monocortical miniplate fixation of mandibular fractures has become a reliable method of providing rigid fixation and eliminating the need for intermaxillary fixation. Recent studies, using a variety of internal fixation techniques, have described high complication rates at the mandibular angle. This article compares the use of one miniplate vs two miniplates in treatment of angle fractures. Since September 1985, 61 patients with 63 mandibular angle fractures have been treated with miniplates. Forty-four fractures were fixed with two miniplates. Six complications (3.1%) occurred, five of which were in the one-miniplate group. The complication rate in the double-miniplate group is the lowest reported of any plating technique. The use of two miniplates has proved to be an effective method of treating mandibular angle fractures.

Traumatic anterior fossa cerebrospinal fluid fistulae and craniofacial considerations.

Traumatic cerebrospinal fluid fistulae may present a diagnostic and treatment challenge to the head and neck surgeon. The clinical presentation may be obscured by associated injuries. This article serves as a guide in the understanding, diagnosis, and management of patients with dural fistulae of the anterior cranial fossa.

Three-dimensional CT reconstruction in midfacial surgery.

Correct preoperative planning is an essential aspect of any surgical procedure and it is equally important when midfacial reconstruction is contemplated. Conventional methods include standard radiographic views, plain tomography, photography, and computerized tomography. All of these methods produce a two-dimensional image of the patient. Three-dimensional computerized tomographic reconstruction allows the surgeon to visualize the entire facial skeletal deformity. The three-dimensional image produced also allows comparison of the deformity to surrounding normal structures, and thus makes the correction of facial asymmetrics more precise. This new modality is particularly useful in the preoperative planning for patients with zygomaticomaxillary defects that result from either trauma or maxillectomy. Illustrative examples of patients in whom autogenous bone graft zygomaticomaxillary reconstruction was performed, after trauma and subsequent to subtotal maxillectomy, are presented. The amount and exact placement of the grafts was determined preoperatively from the analysis of the three-dimensional CT reconstruction, and the surgical planning was thereby simplified.

Profile planning based on alterations in the positions of the bases of the facial thirds.

To analyze the profile properly, the size and position of the bases of the facial thirds must be known. In this study an average face was created by standard cephalometrics. The bases of the facial thirds were then moved in the horizontal or vertical direction, and the soft tissue profile was drawn to correspond to the skeletal changes. The results show how underlying skeletal abnormalities influence the profile. The terms used to describe the size and position of the bases serve as an aid in profile planning.

Rhabdomyosarcoma of the infratemporal fossa: diagnostic dilemmas and surgical management.

We present a rare case of embryonal rhabdomyosarcoma in the infratemporal fossa presenting as an atypical facial pain syndrome. Radiographic imaging of the patient is discussed, and magnetic resonance imaging is recommended as the diagnostic modality of choice when mass lesions of the infratemporal fossa are suspected. Finally, a temporal approach to the infratemporal fossa is described, along with its advantages as an application for tumor resection in this anatomic region.
