Interfacility Transfer Guidelines for Isolated Facial Trauma: A Multidisciplinary Expert Consensus.

BACKGROUND: The objective of this study was to develop guidelines for the transfer of patients with isolated craniomaxillofacial trauma. METHODS: A national, multidisciplinary expert panel was assembled from leadership in national organizations and contributors to published literature on facial reconstruction. The final panel consisted of five plastic surgeons, four otolaryngologist-head and neck surgeons, and four oral and maxillofacial surgeons. The expert panelists' opinions on transfer guidelines were collected using the modified Delphi process. Consensus was predefined as 90 percent or greater agreement per statement. RESULTS: After four Delphi consensus building rounds, 13 transfer guidelines were established, including statements on fractures of the frontal sinus, orbit, midface, and mandible, as well as soft-tissue injuries. Twelve guidelines reached consensus. CONCLUSIONS: The decision to transfer a patient with craniomaxillofacial trauma to another facility is complex and multifactorial. While a percentage of overtriage is acceptable to promote safe disposition of trauma patients, unnecessarily high rates of secondary overtriage divert emergency medical services, increase costs, delay care, overload tertiary trauma centers, and result in tertiary hospital staff providing primary emergency coverage for referring hospitals. These craniomaxillofacial transfer guidelines were designed to serve as a tool to improve and streamline the care of facial trauma patients. Such efforts may decrease the additional health care expenditures associated with secondary overtriage while decompressing emergency medical systems and tertiary emergency departments.

Ectopic Molar Removal from the Ramus/Condyle Unit: A Minimally Invasive Approach.

Ectopic molars within the mandibular ramus/condyle unit, although rare, present a unique challenge to the surgeon. Multiple approaches have been described in the literature for their removal. A review of the English literature on the subject of mandibular ectopic molars and their epidemiology, etiology, indications for removal, and surgical techniques was completed. In addition, a case report is presented of an ectopic mandibular molar in the mid-ramus region which was removed via a minimally invasive, intraoral, technique combining the use of endoscopy and piezoelectric surgery. The authors advocate this technique as it offers the following advantages: avoidance of injury to branches of the facial nerve, unaesthetic scars, and sialocele formation; maximization of surgical field visualization with limited dissection; ability for safe sectioning of the tooth with minimal risks to adjacent structures; and precise bone removal, reducing the risk of iatrogenic or postoperative mandible fracture.

Mandibular blastomycosis: A case report and review of the literature.

INTRODUCTION: Blastomycosis is an endemic mycosis in the United States known to primarily cause pneumonia. However, dissemination to different organs including the musculoskeletal system has been described. CASE REPORT: We report a case of mandibular blastomycosis in a healthy patient with no evidence of lung involvement. A 28 year-old female presented with recurrent right mandibular osteomyelitis despite courses of antibiotics and surgical debridement. She eventually underwent right hemimandibulectomy. Budding yeasts visualized on Gomori Methenamine-Silver (GMS) and Periodic acid-Schiff (PAS) were morphologically consistent with Blastomyces dermatitidis, and intra-operative cultures showed growth of mold identified as B. dermatitidis by DNA probe. She was placed on a prolonged course of itraconazole with clinical improvement. We also reviewed the literature and found 5 cases of similar presentation which we briefly summarized in this present case report. CONCLUSION: Blastomycosis should be considered in patients with recurrent or persistent mandibular osteomyelitis even in immunocompetent individuals.

Posttraumatic Parotid Sialocele Complicating a Mandibular Fracture: A Case Report.

Blunt trauma to the parotid resulting in the formation of a sialocele is rare, with only three cases identified in the literature. We present a unique case involving a 32-year-old man with blunt trauma resulting in a left mandibular angle fracture. The patient underwent open reduction and internal fixation of the left mandibular angle fracture via transoral approach. At follow-up, after resolution of the edema from the injury, a sialocele was noted in the region of the left anterior parotid gland. The patient was treated conservatively with antisialagogues, pressure dressings, and multiple percutaneous aspirations that ultimately resulted in resolution of the sialocele.

Zygomaticomaxillary complex fractures: diagnosis and treatment.

PURPOSE OF REVIEW: To provide an overview of zygomaticomaxillary complex (ZMC) fractures and their treatment. Aspects of anatomy, diagnosis, and treatment objectives of these common fractures will be reviewed including recent literature. RECENT FINDINGS: Advances in technology such as guided surgery have allowed for better outcomes and a reduction in surgeon variability with regard to postoperative results. The use of titanium and bioresorbable mini screws and plates have expanded the ability to achieve stable and predictable results. There are many different challenges and techniques that are acceptable to treat zygoma fractures. Surgeon preference and training dictate these methods that vary among specialties. SUMMARY: ZMC fractures are commonly encountered in the trauma setting. Although there is a multitude of treatment methods available, the ultimate goal for any surgeon should be to reproduce premorbid form and function. The availability of techniques such as 3D navigation, contralateral mirroring, and advances in fixation technology have shown promise for better outcomes, particularly in severely comminuted or displaced fractures.

Treatment of peri-implantitis and the failing implant.

Appropriate treatment of implants is becoming increasingly important for the general dentist as the number of implants placed per year continues to increase. Early diagnosis of peri-implantitis is imperative; initiating the correct treatment protocol depends on a proper diagnosis. Several risk factors exist for the development of peri-implantitis, which can guide patient selection and treatment planning. Treatment of peri-implantitis should be tailored to the severity of the lesion (as outlined by the cumulative interceptive supportive treatment protocol), ranging from mechanical debridement to explantation. Several surgical and nonsurgical treatment alternatives exist. There is little consensus on superior treatment methods.

Update on the management of dentoalveolar trauma.

PURPOSE OF REVIEW: Dentoalveolar injuries are the most common type of facial injury and are often associated with concomitant facial fractures. These injuries may initially be seen by surgeons who do not have formal dental training. This article reviews the assessment and management of dentoalveolar fractures. RECENT FINDINGS: Semi-flexible splinting of traumatized teeth for shorter periods of time than previously suggested is associated with better long-term outcomes. The use of dental implants to replace teeth lost to trauma is a predictable restorative option. SUMMARY: Surgeons need to be aware that dentoalveolar injuries may be a marker for other injuries. Prompt relocation and splinting of displaced teeth is associated with better outcomes.

Use of the BioHole™ device for the creation of tunnel tracks for buttonhole cannulation of fistula for hemodialysis.

Buttonhole cannulation is a method of cannulation of native arteriovenous fistulae traditionally practiced by self-cannulators. At St Michael's Hospital, this method has been modified to allow its use in problematic fistulae by multiple cannulators. In a busy dialysis unit, the need for a few specific cannulators to establish the tunnel tracks in combination with the variable dialysis schedules creates logistical challenges. A new method of creating tunnel tracks with the use of the BioHole™ device was evaluated. Buttonhole tracks were created in 12 patients using a peg of polycarbonated material with a holder (BioHole™ kit). The peg was inserted into the path left by the hemodialysis sharp needle following the index cannulation. Four of the 12 patients had an alternate access. Buttonhole tracks were successfully created in all the patients, albeit in 2 patients, the initial attempt to establish buttonhole tracks was aborted due to complications and the procedure was rescheduled. Compared with the modified buttonhole technique, pain on cannulation following track creation was significantly less in the BioHole™ group (P < 0.001). Ease of cannulation was significantly improved in the BioHole™ group (P<0.05) when compared with that in thrice-weekly patients using the modified buttonhole technique. Hemostasis postdialysis did not differ between the study groups. The use of the BioHole™ device is effective in the creation of tunnel tracks for buttonhole cannulation, is associated with less pain, and simplifies the logistics of arranging patient and nurses' schedules.

Analysis of results in early versus late midface fracture repair.

OBJECTIVE: To evaluate the complication rate in relation to the timing of surgical repair of midface fractures. STUDY DESIGN AND SUBJECTS: Retrospective chart review at a level 1 trauma center. RESULTS: Thirty-four patients were evaluated. Overall complication rate was 23.5% with no significant difference between the early repair (21.1%) and late repair (26.7%) groups. The scope of facial fracture repair was similar between the two groups as measured by the number of screws used and through an injury quantifying system. The only variable that tended toward significance was intraoperative blood loss, which was greater in the early repair group (P = 0.06). CONCLUSIONS: There is no clear consensus with respect to timing of midface trauma repair. Early repair may result in greater blood loss. Further study is needed to help establish a more precise recommendation for the timing of midface trauma repair.

Strategies for avoiding complications with vascularized bone flaps in head and neck microvascular reconstruction.

Effective osseous reconstruction of the head and neck after congenital, traumatic, and particularly ablative oncologic procedures is a relatively recent innovation. Whereas pioneers led with individual donor sites, it is only in the past 20 years that most centers have developed teams comfortable with use of the four common donor sites for free flaps: iliac crest, fibula, radius, and scapula. Calvarium, though much less frequently used, is a useful donor site for specific reconstructive challenges. Less commonly used sites such as femur, humerus, and rib have not proved universally reliable. This article aims to illustrate some refinements and pitfalls in vascularized osseous reconstruction of the head and neck using the well-recognized flaps, including calvarium, in a variety of pathologic conditions, recipient-site defects, and comorbidities. Strategies for error avoidance will be emphasized. The authors hope that this will support the concept of a reconstructive "toolbox" for this complex area.

The salvage of aneurysmal fistulae utilizing a modified buttonhole cannulation technique and multiple cannulators.

We describe the St Michael's Hospital (SMH) modified buttonhole (BH) cannulation technique as a method that offers a solution for fistulae with aneurysmal dilatation due to repetitive cannulation in a restricted area. This is a prospective cohort study of 14 chronic hemodialysis (HD) patients with problematic fistulae (marked aneurysmal formation and thinning of the overlying skin, bleeding during treatment, and prolonged hemostasis post-HD) because of repetitive, localized cannulation. Each patient was followed for 12 months. The protocol was as follows: creation of tunnel tracks by 1 to 3 experienced cannulators per patient, using sharp needles. After the tunnel tracks were established and cannulation was easily achieved with dull needles, additional cannulators were incorporated with the guidance of a mentor. Bleeding from cannulation sites during dialysis ceased within 2 weeks and skin damage resolved within 6 months in all patients. Hemostasis time postdialysis decreased from 24 to 15 min. Cannulation pain scores decreased significantly. Access flows and dynamic venous pressure measurements remained unchanged. No interventions were required to maintain access patency. In 2 cases, the aneurysms became much less evident. Complications included one episode of septic arthritis and one contact dermatitis. A third patient developed acute bacterial endocarditis 9 months following completion of her follow-up. The SMH modified BH cannulation technique can salvage problematic fistulae, prevent further damage, and induce healing of the skin in the areas of repetitive cannulation. This technique can be successfully achieved by multiple cannulators in a busy full-care HD unit.

Hyperbaric oxygen therapy: a meeting place for medicine and dentistry.

The hyperbaric medicine facility at Hennepin County Medical Center has been serving patients from throughout the region for more than 40 years. Some of these patients have head and neck cancer and are suffering delayed complications of radiation therapy. Such patients are often referred by dentists, oral surgeons, and otolaryngologists. This article summarizes outcomes for patients who have received hyperbaric oxygen therapy for 3 conditions: soft-tissue radiation injury before undergoing dental extractions, osteoradionecrosis, and soft-tissue radiation injury prior to receiving dental implants in the irradiated area.
