Management of frontal sinus fractures: a review of 96 cases.

OBJECTIVES: The optimal treatment algorithm for frontal sinus fracture management remains ill-defined. The purpose of the study was to classify fracture types, review management methods, document associated injuries, and identify complications associated with various treatment options. STUDY DESIGN: The authors conducted a retrospective chart review evaluating a 13-year experience with frontal sinus fracture management. METHODS: Complete medical records of 96 frontal sinus fracture patients treated by the University of Kentucky Otolaryngology Service from 1990 to 2003 were reviewed. RESULTS: The average patient age was 39 years. Fifty percent of the fractures involved the anterior table of the frontal sinus alone, and 50% involved both anterior and posterior tables. Forty-seven percent of the injuries were managed with observation, whereas 50% of patients underwent surgical repair. In the surgical group, 60% underwent open reduction and internal fixation (ORIF), 23% had a cranialization procedure, and 17% underwent sinus obliteration. The average length of follow up was 9 months. Complications occurred in 17% of the patients (5% in the nonsurgical group and 12% in the surgical group). CONCLUSION: Our results support conservative management of nondisplaced or minimally displaced fractures based on the low complication rate seen in this series. Significant bone displacement can frequently be managed with simple ORIF. Complex fractures affecting the orbit or intracranial contents require cranialization or possibly obliteration. A subset of patients with suspected frontal sinus outflow obstruction can be considered for observation or simple ORIF with close follow up and endoscopic repair if outflow complications manifest.

The acetabular reamer: a unique tool for anterior iliac crest bone graft harvesting.

Bone grafting is often required in craniofacial reconstruction. Morselized corticocancellous bone grafts are particularly useful in applications such as filling and contouring irregular bony defects. Obtaining grafts of this consistency by traditional methods is difficult. An efficient harvesting method that can produce such grafting material in clinically useful quantities is needed. We report the use of a mechanical acetabular reamer for the purpose of harvesting a bone graft from the iliac crest.

PURPOSE OF REVIEW: Regenerative medicine holds promise for the restoration of tissues and organs damaged by wear, trauma, neoplasm, or congenital deformity. Tissue engineering combines the disciplines of cell biology and biomedical engineering to effect the design and maturation of various tissues. Despite progress in some areas of tissue regeneration, there has not been significant translation to clinical practice. This article reviews the present understanding of and advances in regenerative medicine, as well as describing limitations in current techniques and areas that need further development. A discussion of the state of the art in the regeneration of skin, cartilage, bone, adipose tissue, and neural tissue is included. RECENT FINDINGS: Differences between extracorporeal and in-vitro tissue engineering are discussed, as well as tissue engineering principles, including the use of bioactive scaffolds, progenitor cells and stem cells, the need for cellular and tissue patterning, microcirculation development, and the use of external stimuli for differentiation. Much needs to be learned about progenitor cell biology, cell-cell interactions, cellular interactions with the extracellular matrix, and about the cues needed for differentiation of functional tissues. SUMMARY: The current limitations in regenerative medicine techniques and the gaps in current knowledge of cellular biology and tissue development represent significant research opportunities in tissue engineering.
