Twenty-six-year experience treating frontal sinus fractures: a novel algorithm based on anatomical fracture pattern and failure of conventional techniques.

Background: Frontal sinus fracture treatment strategies lack statistical power. The authors propose statistically valid treatment protocols for frontal sinus fracture based on injury pattern, nasofrontal outflow tract injury, and complication(s). Methods: An institutional review board–approved retrospective review was conducted on frontal sinus fracture patients from 1979 to 2005. Fractures were categorized by location, displacement, comminution, and nasofrontal outflow tract injury. Demographic data, treatment, and complications were compiled. Results: One thousand ninety-seven frontal sinus fracture patients were identified; 87 died and 153 were excluded because of insufficient data, leaving a cohort of 857 patients. The most common injury was simultaneous displaced anteroposterior walls (38.4 percent). Nasofrontal outflow tract injury constituted the majority (70.7 percent), with 67 percent having a diagnosis of obstruction. Of the 857 patients, 504 (58.8 percent) underwent surgery, with a 10.4 percent complication rate; and 353 were observed, with a 3.1 percent complication rate. All complications except one involved nasofrontal outflow tract injury (98.5 percent). Nasofrontal outflow tract injuries with obstruction were best managed by obliteration or cranialization (complication rates: 9 and 10 percent, respectively). Fat obliteration and osteoneogenesis had the highest complication rates (22 and 42.9 percent, respectively). The authors’ treatment algorithm provides a receiver operating characteristic area under the curve of 0.8621. Conclusions: A frontal sinus fracture treatment algorithm is proposed and statistically validated. Nasofrontal outflow tract involvement with obstruction is best managed by obliteration or cranialization. Osteoneogenesis and fat obliteration are associated with unacceptable complication rates. Observation is safe when the nasofrontal outflow tract is intact.

Predictable Patterns of Intracranial and Cervical Spine Injury in Craniomaxillofacial Trauma: Analysis of 4786 Patients

Background: Patients presenting with traumatic craniomaxillofacial fractures often have occult concomitant injuries. This study was designed to determine whether facial fracture patterns are associated with a particular constellation of concomitant head and neck injuries. Methods: A retrospective review of 4786 consecutive patients diagnosed with maxillofacial fractures at a dedicated urban trauma center from 1998 to 2005 was conducted; maxillofacial fractures and cervical spine injuries were grouped by dividing the craniomaxillofacial skeleton and cervical spine into thirds. Univariate and multivariate logistic regression analyses were used to identify associations between facial fractures and other traumatic injuries. Results: Among all patients with facial fractures, 461 (9.7 percent) also had cervical spine injuries and 2175 (45.5 percent) had associated head injuries. Fractures of the upper face were associated with increased likelihood of mid lower cervical spine injuries, severe intracranial injuries, and increased mortality rates. Unilateral mandible injuries were associated with an increased likelihood of having upper cervical spine injuries, whereas unilateral midface injuries were associated with basilar skull fractures and several intracranial injuries. Finally, bilateral midface injuries were associated with basilar skull fracture and death. Conclusions: Craniomaxillofacial fractures are commonly associated with head and cervical spine injuries that involve predictable patterns of force dispersion from the maxillofacial skeleton and transmission to the cranial vault and cervical spine. These results suggest that concomitant injuries should be investigated closely with distinct types of facial fractures.

Posterolateral skull base reconstruction using the supraclavicular artery island flap.

The supraclavicular artery island (SAI) flap is a viable fasciocutaneous option for the reconstruction of head and neck defects. Although authors have reported success using SAI flaps for various reconstructive indications, concerns of a tenuous blood supply and distal ischemia have previously limited its use in the posterolateral skull base. This case series reports the outcomes of 5 consecutive patients receiving SAI flaps for posterolateral skull base reconstruction. All flaps were harvested in less than 1 hour with primary closure of all donor sites. A single patient developed superficial necrosis of the distal flap, which was repaired with a full-thickness skin graft. There were no other complications, and no donor site morbidity was observed. The SAI flap is an excellent option for the reconstruction of posterolateral skull base defects. The close color match, easy harvest within 1 hour, lack of microsurgical anastomosis, and absence of donor site morbidity support its continued utilization.

Definitive Treatment of Persistent Frontal Sinus Infections : Elimination of Dead Space and Sinonasal Communication

Background: Frontal sinus injury involving nasofrontal outflow tract obstruction is routinely managed by obliteration or cranialization; however, a small percentage of patients develop persistent indolent infections despite routine measures. The authors discuss the course of persistent infection following frontal sinus fractures and propose a novel treatment that definitively obliterates and separates the nasofrontal outflow tract from the cranium in these patients. Methods: Seven consecutive patients with persistent indolent infections associated with frontal sinus fractures were identified and treated at the R Adams Cowley Shock Trauma Center and The Johns Hopkins Hospital from 2005 to 2008. Results: There were three women and four men, with an average age of 41 years. Injury resulted from motor vehicle crashes (n = 4), motorcycle crash (n = 1), fall (n = 1), and other accident (n = 1). All patients were previously treated with conventional techniques (average, 3.6 procedures and 11 years from initial injury) and prolonged antibiotic therapy without resolution of symptoms. Definitive treatment included radical débridement and obliteration with a free fibula flap in a single stage. All flaps survived and resulted in complete sinonasal separation and eradication of infection. There were no donor-site or frontal sinus complications. Conclusions: Radical débridement, meticulous removal of the tenacious sinus mucosa, and reconstruction with a free fibular flap in a single stage is a superb choice for eliminating persistent infectious complications associated with frontal sinus fractures in patients who have failed conventional management. The fibular flap provides a secure horizontal buttress, seals the nasofrontal outflow tract with vascularized muscle, and obliterates dead space.

Restoring the failed cranioplasty: nonanatomical titanium mesh with perforator flap.

The calvaria is covered by a thin, well-vascularized soft-tissue envelope, providing a rich environment for a variety of local and regional flaps.1 Composite cranial vault restoration aims to protect the brain and restore cranial form. Primary reconstructions result in good outcomes, provided there is adequate quality and quantity of soft tissue. The complexity also increases with the size and thickness of the defect, and the predictability and durability decrease with attenuating factors. Local and systemic factors such as malnutrition, extensive zone of injury from radiation therapy, and multiple surgical explorations play a pivotal role and potentially complicate routine options. Thus, composite calvarial defects within a field of multiple surgical interventions or radiation therapy result in less predictable outcomes. Secondary cranioplasty in the setting of an attenuated soft-tissue envelope presents a unique challenge. The purpose of this article is to present a novel alternative for managing the failed cranioplasty with associated soft-tissue deficit that includes distant tissue transfer in the form of perforator-based flaps in addition to a nonanatomical titanium mesh cranioplasty, ensuring rigid brain protection and durable tissue coverage.

Is simultaneous surgical management of advanced craniofacial osteoradionecrosis cost-effective?

Background: Osteoradionecrosis is a serious complication of head and neck radiotherapy. Advanced cases are not amenable to periodic debridement, systemic antibiotics, or hyperbaric oxygen therapy. The authors sought to describe a cost-effective approach for patients with advanced craniofacial osteoradionecrosis. Methods: Fifteen consecutive patients with craniofacial osteoradionecrosis were treated with radical resection and immediate microvascular free flap reconstruction at Johns Hopkins Hospital or R Adams Cowley Shock Trauma Center from 2002 to 2008. Demographic data were reviewed, and procedure costs were used to compare treatment options. Results: All patients presented with intractable osteoradionecrosis, and most failed conservative therapy. Most cases (60 percent) involved the mandible, and the fibula was the flap of choice (73 percent). The median follow-up was 14 months, with 13 percent complications. Relative cost analysis for hyperbaric oxygen, surgical debridement, and a hospital stay was
