Maxillofacial fractures among non-indigenous ethnic groups in the Irish national maxillofacial unit: a review.

BACKGROUND: This study investigates maxillofacial fractures in non-indigenous ethnic groups who were reviewed in the national maxillofacial unit in Ireland. The aim of this study was to highlight any potential trends in presentation of facial fractures in non-indigenous groups in comparison to previous reports which have included all ethnicities. This unique study is based on the fact that Ireland has only recently transformed into a diverse, multi-cultural country. This is unlike countries such as the UK and USA which have a long history of multicultural integration. MATERIALS AND METHODS: This retrospective study evaluated the trauma database of 4761 patients with 5038 fractures who attended the national maxillofacial unit over a 5-year period from 2015 to 2019. Parameters included age, gender, mechanism of injury, fracture sustained, time of the day, day of the week, month of injury, and the referral source were obtained from patient records. RESULTS: The study identified 456 patients who did not identify as being born in Ireland, with 384 males and 72 females. The most common fracture seen was of the zygomatic bone, and the most common mechanism of injury was alleged assault for this cohort. Most injuries occurred in late afternoon with Friday being the most common day of the week. CONCLUSION: This study shows how maxillofacial units need to adapt to the changing trends in Irish demographics with increased demand for resources such as translation services. A further study could evaluate the rapidly changing demographic with mass migration of people currently seeking refuge in Western Europe.

Mandibular angle fractures: a demographic review, with particular reference to post-operative complications.

BACKGROUND: Mandibular angle fractures (MAF) have a recognized complexity of treatment and an increased risk of incurring complications. METHODS: This retrospective study included 45 consecutive patients who were diagnosed with an isolated MAF and no other facial fractures. The average age was 27.3 (SD = 7.7). RESULTS: A comparatively low rate of complications (11.1%) and a low rate of reoperation (1.8%) are reported, along with a significant role of smoking in complications (p = 0.022). A non-significant association was noted between complications, male gender and assault as an aetiological factor. CONCLUSIONS: Review of the data from this study confirms that complication rates for patients attending the National Maxillofacial Unit are similar to or better than that of international studies. An overview of the aetiology of fracture complications is included.

Maxillofacial fractures in females: a 5-year retrospective review.

BACKGROUND: This retrospective study reviews the maxillofacial fractures (MF) over a 5-year period at the National Maxillofacial Unit, St James Hospital Dublin, with an emphasis on female patients. MATERIALS AND METHODS: The trauma database was analysed from January 2015 to December 2019. The following demographic details were recorded: patient age and gender, mechanism of injury, and facial fracture sites. This retrospective study did not require approval from the local IRB. RESULTS: A total of 4761 patients had facial fractures during the study: 1125 (24%) female, 3636, (76%) male. Females had 1190 facial fractures, with two fracture peaks: 20-39 years and 70-89 years. In males, the majority of fractures occurred between 20 and 39 peaking at 20-29 years and tailed off thereafter. In the females the most common fracture sites were zygomatic 402 (34%), nasal 311(26%), orbital (22%), and mandibular 141(12%). There were also smaller percentages of frontal (0.8%), maxillary (4%), and Le Fort fractures (1%). Two hundred and sixty-two (23%) females were managed surgically and 853 (77%) non-surgically. CONCLUSION: This study confirms maxillofacial fractures are less common in females. The female age distribution demonstrates two peaks, one in early adult and a second in old age. This may be explained by females living longer and independently and at risk for falls. The most commonly reported fracture aetiology in females was "falls." This raises concerns as to whether "falls" are used to explain an assault. There is an informal concern amongst maxillofacial surgeons that females presenting with facial trauma may be the victims of domestic violence, which may be denied by the victims.

Oral lymphangiectasias and Crohn's disease: two case reports.

Lymphangiectasias, or acquired lymphangiomas, are rare in the oral cavity, more typically occurring on the skin or the genital area and, to our knowledge, have not been reported previously in association with Crohn's disease. Lymphangiectasias can occur at any age and develop secondary to chronic obstruction of the lymphatics. This differentiates them from congenital lymphangiomas, which are congenital malformations of the lymphatic system. We present 2 cases of oral lymphangiectasias associated with Crohn's disease, one of which was treated successfully with cryotherapy.

Oral Squamous Cell Carcinoma Presenting in a Patient Receiving Adalimumab for Rheumatoid Arthritis.

The efficacy of biologic agents in the treatment of inflammatory immune-mediated conditions has been clearly shown, but there also are numerous reports of adverse effects. Most reported adverse effects have been associated with tumor necrosis factor-α (TNF-α) inhibitors and include a possible increased risk of malignancy. There have been some reported cases of oral cancer developing in patients treated with TNF-α inhibitors. This case report describes a patient who was taking adalimumab for rheumatoid arthritis and who presented with a squamous cell carcinoma (SCC) in the mandible. Diagnosis was complicated because the clinical appearance was of a nonhealing extraction socket and the patient had a history of bisphosphonate therapy. An initial diagnosis of bisphosphonate-related osteonecrosis of the jaws was made, which delayed the commencement of appropriate treatment. This case highlights the importance of ruling out SCC in patients taking biological agents with unusual symptoms.

The management of osteoradionecrosis of the jaws--a review.

PURPOSE: To review the conservative and surgical management options of osteoradionecrosis, in particular, highlighting the recent the use of anti-radiation fibrosis drugs (pentoxifylline, tocopherol and clodronate). MATERIAL AND METHODS: We performed a literature review. The management options were divided into two groups, conservative and surgical management. RESULTS: Over the years several treatment options have been proposed including; conservative management (antibiotics, analgesics, oral hygiene), ultrasound therapy, hyperbaric oxygen therapy, surgical resection with reconstruction and more recently the use of anti-radiation fibrosis drugs (pentoxifylline, tocopherol and clodronate). Early or low grade ORN can be managed conservatively using a combination of treatment options. In advanced or refractory cases of ORN (pathological fracture, orocutaneous fistula) surgical treatment, at present, remains the only treatment option available. A new understanding of the pathophysiology of ORN (radiation induced fibroatrophic process) has lead to the development of new therapeutic management regimes. CONCLUSION: In advanced or refractory cases of ORN surgical treatment, including microvascular reconstructive techniques for bone and soft tissue, remains the only option available.

Reconstruction of a bilateral mandibular defect due to trauma using a single fibula free flap.

The reconstruction of noncontiguous bilateral mandibular defects using a single bony free flap is rarely performed because such defects are seldom encountered. This report describes the reconstruction of a bilateral body defect caused by shrapnel injury. A free vascularized osteomyocutaneous fibula flap was designed to replace 2 mandibular defects in the patient. The midportion of the fibula was resected without damage to the periosteum and vascular pedicle, and a skin paddle was used to monitor the flap. This would appear to be the first report of its use in the reconstruction of bilateral mandibular defects from trauma.
