The psychological sequelae of maxillofacial trauma: a scoping review of the literature

Managing the physical sequelae of facial trauma is routine for the maxillofacial surgeon. However, managing the psychological consequences is more challenging. The often violent mechanism of injury, changes in appearance, altered self-perception, and self-confidence can significantly impact daily life. This review summarises the literature regarding post-traumatic stress disorder (PTSD) and facial trauma, highlighting evidence to guide clinical practice. PubMed and MEDLINE were searched for relevant keywords and MeSH headings. Articles between 2000-2022 were independently reviewed by two authors. Articles were excluded if the full text was not available in English, did not relate to facial trauma, or was not related to PTSD/psychological sequelae. A total of 211 articles were retrieved. The most common reasons for exclusion were papers not reporting psychological outcomes (n = 68) or not relating to facial trauma (n = 35). Articles were sub-categorised to enable evaluation of key themes. Categories included children and adolescents, cross sectional, longitudinal studies, and interventional studies. Whilst there were potential confounders such as socioeconomic factors, overall, patients who had experienced facial trauma (regardless of the mechanism of injury) had an increased risk of PTSD and anxiety/depression. PTSD following facial injury is increasingly recognised as an important issue. A robust evidence base is desirable to inform clinical practice and provide holistic care to often vulnerable patients. Identifying those at increased risk of negative psychological sequelae is essential. We have appraised the literature relevant to OMFS trauma clinicians.     

The prevalence of psychological distress in a sample of facial trauma victims. A comparative cross-sectional study between UK and Australia

Aim

The potential psycho-social sequelae of traumatic facial injury have received increasing attention in recent years, however there remains paucity of cross-national comparative data on the prevalence of psychological distress following such trauma. The aim of the present study was to investigate and compare the prevalence of anxiety and depression in an adult patient group who have been treated for maxillofacial trauma, and who attend a follow-up clinic in either the West Midlands, UK or New South Wales (NSW), Australia. By using an identical methodological and statistical approach, we hoped to add to the available information on the incidence of early psychological distress in patients following facial trauma.

Method

This was a comparative cross-sectional study. A sample of fifty consecutive adult victims of facial trauma in the West Midlands UK, was compared to a group of fifty-two facially injured patients in NSW, Australia. Demographic data was collected, following which the Hospital Depression and Anxiety Scale (HADS) were applied to both groups of patients.

Results

Psychometric scores suggestive of anxiety and depressive state were common in both groups of patients. The mean HADS depression subscale score for UK patients compared to Australian patients was not significantly different (5.94 versus 5.54 p = 0.62). This was also the case for the HADS anxiety subscale (5.96 versus 5.94 p = 0.98). Although the number of patients achieving scores suggestive of a ‘caseness’ for co-morbid psychological state was higher within the UK sample when compared to the Australian group (20% versus 11.5% for HADS depression subscale, and 20% versus 15% for HADS anxiety subscales respectively); these differences did not reach statistical significance.

Conclusion

This cross-national comparative study has shown that anxiety and depression in facial trauma victims were comparable in both settings.     

Mental health screening in facial cosmetic surgery: a narrative review of the literature

The popularity of cosmetic surgery is on the increase with the face being one of the most common anatomical areas operated on. Pre-existing mental health conditions can be associated with adverse patient outcomes after cosmetic surgery and can result in deterioration of postoperative mental health and lack of patient satisfaction. Therefore, identifying the presence of psychiatric disorders through preoperative screening should be considered during consultation for facial cosmetic surgery. In this study, we reviewed the types of preoperative mental health screening tools used in cosmetic facial surgery and the prevalence of mental health conditions among patients undergoing cosmetic facial surgery. A literature search was conducted on Pubmed, Prospero, Dynamed, DARE, EMBASE, and COCHRANE databases. A total of 12 articles fulfilled the inclusion criteria. A total of 2194 participants were included in this review. Rhinoplasty (n=1154), blepharoplasty (n=138) and rhytidectomy (n=83) were the most performed facial cosmetic procedures, respectively. A total of 758 (34.1%) had a diagnosis of a potential mental health problem following the preoperative screening. With body dysmorphic disorder (BDD) being the most common (20.0%). The BDD questionnaire was the most used screening tool (n=4). Mental health diagnoses were more common in patients in low-income countries (48.4%) compared to patients from non-low-income countries (25.7%). Given our findings, we propose the routine use of mental health screening tools in all patients undergoing facial cosmetic surgery. This will improve satisfaction rates post-facial cosmetic surgery and may reduce the number of unnecessary procedures.     

The development of acute post-traumatic stress disorder after orofacial injury: a prospective study in a large urban hospital.

PURPOSE: Psychologic distress is a common outcome among trauma survivors. This report examines both the development and predictors of acute post-traumatic stress disorder (PTSD) symptoms in a sample of US inner-city orofacial trauma survivors seeking treatment in a publicly funded hospital. PATIENTS AND METHODS: Baseline data were collected from 336 patients seeking urgent care for an oral injury (mandibular or midfacial fracture). Participants were predominantly unemployed, unmarried, African American or Hispanic men in their 30s. One-month follow-up assessments of PTSD symptoms were conducted on the available 84% of the sample. RESULTS: Absolute levels of PTSD symptoms were high at 1 month; 25% of the sample appeared to meet diagnostic criteria for acute PTSD, based on a self-report of symptoms. Variables associated with self-reports of higher rates of PTSD symptoms included older age, being female, prior psychologic disturbance as reflected in lifetime and current mental health and social service need and use, exposure to and distress at a prior trauma as well as overall high rates of stressful life events in the past year, injury pain, psychologic distress at hospital discharge, and unmet social support needs during the recovery phase. CONCLUSIONS: A substantial subsample of these traumatized medical patients had negative psychologic outcomes at 1 month. Results underscore the potential use of screening survivors of orofacial injury at urban trauma centers for PTSD and developing systems of care that facilitate referral to appropriate psychologic treatment.     

Health-related quality of life in Nigerian patients with facial trauma and controls: a preliminary survey

We examined the health-related quality of life (HR QoL) of patients with facial trauma and compared it with that of healthy controls; temporal changes in HR QoL of patients over 12 weeks compared with baseline values; and whether the risk of depression could be identified by baseline HR QoL. For 26 months we recruited 126 consecutive patients with facial injuries and 126 age and sex-matched healthy controls for the study. Enrollment criteria included age 18 years and over, Glasgow coma scale score on admission of 12 and over, and duration of stay of more than 24 hours. HR QoL was measured using the 26-item World Health Organization Quality of Life Questionnaire (WHO QoL-Bref), and depression was measured with the Hospital Anxiety and Depression Scale (HADS). Scores in all domains of the WHO QoL-Bref (physical, psychological, social relations, and environment) were considerably reduced in injured patients compared with controls. During follow up there were improvements only in the domains of physical health and environment, but not in psychological health. There was a significant reduction in the HR QoL domain of social relationships with time. The regression equation for all four QoL domains as predictors was significantly related to depression scores throughout the study period. Patients with facial injuries are at risk of poor QoL after trauma. There was a high incidence of depression throughout the follow-up period, and poor QoL at baseline predicted depression during follow-up.

Quality of life,psychological wellbeing and treatment needs of trauma and head and neck cancer patients

There is increasing evidence that patients treated for trauma or cancer of the head and neck may go on to experience psychological distress. We aimed to measure the impact of this on their quality of life (QoL) and to explore their willingness to be referred for psychological support. A total of 96 patients with facial injuries and 124 with cancer of the head and neck completed a self-reported questionnaire to identify psychological distress (Hospital Anxiety and Depression Scale (HADS) and the Acute Stress Disorder (ASD) Scale), quality of life (WHOQoL-BREF), satisfaction with treatment, and willingness to accept psychological support. Thirty-nine percent of patients showed high levels of depressive symptoms and 43% reported high levels of anxiety; 43% in the trauma group and 12% in the cancer group had high ASD scores. Patients with high scores on the HADS reported poorer QoL, and 40% of those with high levels of psychological distress were willing to consider psychological support. Despite the fact that patients report high levels of satisfaction with their medical and surgical care, many have psychological problems and have needs that are not being met. A large proportion would use psychological support services.     

Psychological complications of maxillofacial trauma: preliminary findings from a Nigerian university teaching hospital.

PURPOSE: This study sought to determine 1) the prevalence of psychological distress in a series of subjects who sustained maxillofacial injuries and 2) temporal changes in psychological functioning over 12 weeks compared with baseline values. PATIENTS AND METHODS: This was a prospective, repeated-measures design study of consecutively recruited subjects at a Nigerian university teaching hospital. A total of 51 subjects with facial injuries had repeated follow-up assessments (10 days, 6 to 8 weeks, and 10 to 12 weeks) after the trauma, using standard instruments. RESULTS: The General Health Questionnaire identified a high prevalence of psychological morbidity in the subjects (90%), with 41.2% and 11.8% scoring above threshold values on the hospital anxiety and depression scales, respectively. Five subjects satisfied the criteria on the Trauma Screening Questionnaire for a diagnosis of post-traumatic stress disorder during the follow-up period. Psychological distress (General Health Questionnaire caseness) remained at high levels during the 2 follow-up assessments. CONCLUSIONS: The management of facial injuries should integrate a multidisciplinary approach that addresses the psychological needs of the patients in both the short term and the long term.     

Psychological issues in oral and maxillofacial reconstructive surgery

Many psychological problems affect patients who have oral and maxillofacial operations. This article reviews these problems among patients with craniofacial conditions, facial injuries, facial cancer, and those having orthognathic surgery. Facial cosmetic surgery is not addressed. Problems such as depression, anxiety, low self-esteem, poor social relationships, and changes in body image are considered. The roles of mental health professionals is emphasised to enhance postoperative satisfaction and to provide a better quality of life for these patients.     

Psychological trauma exposure and trauma symptoms among individuals with high and low levels of dental anxiety

This questionnaire-based study investigated the traumatic background and trauma-related symptomatology among 141 treatment-seeking individuals with high levels of dental anxiety and among a low-anxious reference group consisting of 99 regular dental patients. The highly anxious individuals reported a significantly higher number of traumatic events, both within and outside the dental or medical setting, than those in the reference group (73% vs. 21%). Horrific experiences in the dental setting were the most common traumatic events reported. Of the highly anxious individuals, 46.1% indicated suffering from one or more of the post-traumatic stress disorder (PTSD) symptom clusters (re-experiencing, avoidance, loss of interest, and insomnia), while in the reference group this percentage was 6%. Severity of dental anxiety was significantly associated with number of screening criteria for specific phobia and the extent to which the anxious subjects displayed symptoms of post-traumatic stress. Two variables were uniquely predictive for positive diagnostic screens for dental phobia and PTSD: having experienced a horrific dental treatment and having been a victim of a violent crime. In conclusion, post-traumatic symptoms are common accompaniments of severe forms of dental anxiety and are experienced even when dental treatment is not imminent.     

Prevalence of whiplash trauma in TMD patients: a systematic review

The purpose of this systematic review was to describe the prevalence of whiplash trauma in patients with temporomandibular disorders (TMDs) and to describe clinical signs and symptoms in comorbid TMD/whiplash compared with TMD localised to the facial region. A systematic literature search of the PubMed, Cochrane Library and Bandolier databases was carried out for articles published from 1 January 1966 to 31 December 2012. The systematic search identified 129 articles. After the initial screening of abstracts, 32 articles were reviewed in full text applying inclusion and exclusion criteria. Six studies on the prevalence of neck trauma in patients with TMD met the inclusion criteria and were included in the review. Two of the authors evaluated the methodological quality of the included studies. The reported prevalence of whiplash trauma ranged from 8·4% to 70% (median 35%) in TMD populations, compared with 1·7–13% in the non‐TMD control groups. Compared with patients with TMD localised to the facial region, TMD patients with a history of whiplash trauma reported more TMD symptoms, such as limited jaw opening and more TMD pain, and also more headaches and stress symptoms. In conclusion, the prevalence of whiplash trauma is higher in patients with TMD compared with non‐TMD controls. Furthermore, patients with comorbid TMD/whiplash present with more jaw pain and more severe jaw dysfunction compared with TMD patients without a history of head–neck trauma. These results suggest that whiplash trauma might be an initiating and/or aggravating factor as well as a comorbid condition for TMD.     

Clinical and psychological characteristics of TMD patients with trauma history

Oral Diseases (2010) 16 , 188–192 Objective: The purpose of this study was to investigate clinical and psychological characteristics of temporomandibular disorders (TMD) patients with trauma history. Materials and methods: The clinical and psychological characteristics of 34 TMD patients with trauma history were compared with those of 340 TMD patients without trauma history. Craniomandibular index (CMI) was used for clinical characteristics of TMD patients. Symptom severity index (SSI) was used to assess the multiple dimensions of pain. Symptom checklist‐90‐revision (SCL‐90‐R) was used for psychological evaluation. Results: Temporomandibular disorders patients with trauma history displayed significantly higher CMI and palpation index. TMD patients with trauma history also exhibited higher values in duration, sensory intensity, affective intensity, tolerability, scope of symptom, and total SSI score. In addition, these patients showed significantly higher values in symptom dimensions of somatization, depression, anxiety, phobic anxiety, and paranoid ideation. Among the symptom dimensions of SCL‐90‐R, somatization showed the most significant correlations with CMI and SSI. Conclusions: Temporomandibular disorders patients with trauma history displayed more severe subjective, objective, and psychological dysfunction than those without trauma history. Pain of myogenous origin, history of physical trauma, and psychosocial dysfunction were all closely related.     

Psychological consequences of maxillofacial trauma: a preliminary study

AIMS: To identify the prevalence of post-traumatic psychological symptoms after maxillofacial trauma and prognostic factors related to poor outcome. METHODS: Thirty-nine patients were assessed within 10 days of injury and 24 again 4-6 weeks later using five standardised self-report measures on each occasion and a short structured interview at the time of initial contact. RESULTS: Specific post-traumatic psychological symptoms were present at initial assessment in 21 patients (54%), with 9 (41%) meeting diagnostic criteria for post-traumatic stress disorder at review 4-6 weeks later. Other psychiatric problems, such as anxiety and depression, were identified by the General Health Questionnaire and the Hospital Anxiety and Depression Scale. Characteristics associated with poorer outcome included: a previous history of psychological distress; fear of the unknown, and female sex. CONCLUSION: These findings highlight the adverse psychological effect of maxillofacial trauma both immediately after the event and 4-6 weeks after injury. Proper assessment of injured patients must include psychological aspects and further research is needed to identify the most appropriate response.     

Prevalence of cervical spine injuries in patients with facial trauma

OBJECTIVE: Injuries to the spine may accompany facial trauma. By using a large computerized database the goal of this case control study was to assess the association between facial and cervical spine injuries among patients sustaining facial trauma. STUDY DESIGN: During a period of 4 years (1995 to 1998) 3083 patients, 10 years or older, with facial injuries were admitted to the University Hospital of Innsbruck's Department of Oral and Maxillofacial Surgery for facial trauma. Records were analyzed for cause of injury, age and gender distribution, frequency and type of injury, and frequency of cervical spine injuries in relation to facial trauma and concomitant injuries. Two hundred six (6.7%) of these patients had experienced a concomitant cervical spine injury (case group). All other patients (2877) were assigned to the control group of facial trauma only. RESULTS: Facial trauma patients with concomitant cervical spine injuries were significantly older (mean age, 42 vs 34 years); no difference existed for the female/male ratio of 30:70. Sports trauma was the main cause of facial trauma in the control group (37.4%), yet traffic accidents accounted for 43.7% of combined facial and cervical spine injuries in the case group. Central mid face fractures dominated in the case group and lateral mid face fractures in the control group. In the case group cervical spine fractures and dislocations occurred in 19.2%. None of them showed evidence of paralysis. Concomitant brain injuries occurred in 21.6% of the case group and 8.8% of the control group. For patients sustaining facial trauma, logistic regression analysis revealed reduced risks for additional cervical spine injuries in younger patients, female patients, absence of brain injury, and in patients with facial soft tissue lesions alone (58.2%) or dental trauma alone (77.5%). CONCLUSION: The results of this study underline the importance of proper clinical and computed tomographic evaluation in cases of facial fractures for recognition of additional cervical spine trauma. Detection of cervical spine trauma can be missed, especially when pain or symptoms from other parts of the body dominate. The typical patient with concomitant neck and facial trauma is male, 40 years old, and usually involved in a traffic accident.

Facial computed tomography use in trauma patients who require a head computed tomogram.

PURPOSE: Head-injured patients admitted to a trauma center may or may not have associated facial fractures. Most head-injured patients undergo head computed tomography (CT) scan early in their evaluation. The question of adding a facial CT at the time of the head CT can be unclear. The aims of our study are 1) to analyze how the facial CT is used in conjunction with the head CT in facial fracture trauma patients, 2) to recognize unique identifiers that would aid the surgeon's decision-making process to order a facial CT in continuity with a head CT, and 3) to examine what is characteristic of head trauma patients who receive a facial CT separately, at some point after the head CT.Materials and methods Data were retrospectively reviewed for a 5-year period at a level I trauma center in which all patients who present with craniomaxillofacial trauma are managed by the oral and maxillofacial surgery (OMFS) service. Included patients must have obtained a head CT during initial resuscitation and be diagnosed with a facial fracture during the same hospital stay. These patients were divided into 3 groups: those who had a 1) head CT only, 2) head CT and facial CT at the same time, and 3) head CT with the facial CT performed at a later time. RESULTS: A total of 9,871 patients were admitted to the trauma service during a 5-year period and 4,926 patients (49.9%) had head CT performed. Of this group, 12% had facial fractures, and the most common associated injury in this group was facial lacerations and concussions. The nasal fracture followed by the orbital fracture was the most common fracture type. Eighty-four percent of the time, the facial CT was used to help diagnose facial fractures in this patient population. The 3 different groups showed unique trends. CONCLUSION: Six points were identified in our study that can augment the physical examination in patients who require head CT. The following points can help prompt the clinician to order a combination head and facial CT: 1) 12% of trauma patients who require a head CT will have a facial fracture, whereas half of these patients will have multiple facial fractures. 2) Orbital fractures are commonly missed in this group and often require a secondary scan such as coronal views for accurate diagnosis. 3) Facial lacerations correlate with ordering a combination head and facial CT. 4) The most common facial fracture identified among patients receiving a trauma head CT is the nasal fracture. 5) The use of the facial CT in more severely injured patients tended to be delayed and was related to increased hospital and intensive care unit days. 6) Only 16% of facial fracture patients who had received an initial trauma head CT did not require further facial CT scanning.     

Oral and facial trauma among paratroopers in the Israel Defense Forces

Abstract – Background: Military fighters are one of the highest risk populations for dental and oro‐facial trauma. The aim of this study was to evaluate the incidence and etiology of oro‐facial injuries among active duty paratroopers in the Israeli Defense Forces. Methods: Paratroopers from selected companies were interviewed using a structured questionnaire regarding oro‐facial trauma during active service years. The study consisted of 311 male paratroopers, with a mean age of 21.1 years (± 1.7). Mean duration of military service until the study was conducted was 25.9 months (± 6.9). Results: Oro‐facial injuries during military service was found in 87 (28.0%) of the participants, with an incidence rate of 129.6 cases per 1000‐fighter‐years. Extra‐oral lacerations (lip, chin, cheek/facial muscles) were the most common injury. Tooth injuries were reported by 48 of the participants, of whom 44 (50.6%) suffered from dental fractures and four (4.6%) from subluxation/luxation. Most oro‐facial injuries occurred in an isolated training or operational field. Thirty‐seven participants (42.5%) reported postevent disturbance and 10 (11.5%) reported loss of operative activities because of the event (mean 8.6 ± 4.0 day loss). Conclusions: Military paratroopers are highly predisposed to oro‐facial trauma. Besides the physical and mental associated damage, these injuries result in the interference of their continuous daily activity. Prevention, mouth‐guard usage and treatment intervention are two important actions that should be adopted to reduce trauma and its interference.     

Traumatic dental injuries and Alpine skiing

Abstract – The purpose of this study was to determine the occurrence and type of traumatic dental injuries after maxillofacial injuries as a result of Alpine skiing. During an 8‐year period (from January 1991 to December 1998) 7600 patients with facial injuries were registered at the Department of Oral and Maxillofacial Surgery, University of Innsbruck, Austria. Of 784 patients with skiing‐related facial injuries (524 males, 260 females) 326 (41.6%) sustained injuries to 639 teeth. The age groups predominantly affected were between 7 and 32 years. Luxation injuries occurred in 338 (53%) teeth, fractures accounted for 270 tooth injuries (42%), and only 35 (5%) were lost at the place of the accident. Of skiers with traumatic dental injuries 58% had concomitant soft tissue injuries, while 23.3% had associated facial bone fractures. The most common causes of injury were falls in 42% (329 patients) and collisions with other persons in 24.1% (189 patients). Being hit by one's own sports equipment (11%) was the third most common cause. Collisions with obstacles accounted for 9% and lift accidents for 5.6% of injuries. The probability of suffering dentoalveolar trauma during skiing varied depending on the injury mechanism. There was a 2–fold risk for dentoalveolar trauma when colliding with objects, a 3.5‐fold risk when hit by one's own equipment and a 8.5‐fold risk during lift accidents. Dental injuries occurred in about 2% of all injured skiers. Dental health professionals should be aware of the high incidence and the distribution of dental trauma and facial injuries caused by skiing.     

Facial trauma in children and adolescents

Most studies on facial trauma in the pediatric age group focus on special subgroups. This investigation encompasses all traumatic facial injuries, minor and major, of children and adolescents. Epidemiological data of the type and pattern of injury of trauma patients less than 19 years of age, treated during a 3-year-period in a large metropolitan trauma centre were reevaluated. Of the 1385 patients, 68% had soft tissue injuries, 24% had dental trauma, and 8% fractures of facial bones. More than 90% suffered from minimal or minor trauma. The leading cause of injury was a fall, predominantly at the toddler stage. In adolescents an adult mechanism of trauma prevailed: over 60% of injuries were sequelae of an assault or altercation. The male sex predominated through all age groups and for all types of injuries. The bulk of soft tissue injuries are located within a small falling zone, extending from the nose to the mental area. There was a rising incidence of fractures of facial bones towards older age groups, mandibular fractures being the most common. Condylar fractures, with their potential impact on further growth of the mandible, are seen frequently in children and adolescents, making up 80% of the fractures of the lower jaw.

US dental health care workers’ mental health during the COVID-19 pandemic

BackgroundThis study was designed to assess the prevalence of anxiety and depression symptoms and understand factors influencing mental health among dental health care workers (DHCWs) during the COVID-19 pandemic.MethodsBeginning in June 2020, 8,902 DHCWs participated monthly in an anonymous longitudinal, web-based survey (response rate, 6.7%). The Patient Health Questionnaire-4 was used to estimate rates of anxiety and depression symptoms. Changes in mental health over time and differences by demographic and practice characteristics, COVID-19 community transmission level, and COVID-19 vaccination status were tested using χ² tests and multilevel multivariable logistic regression.ResultsAnxiety symptom rates peaked in November 2020 (28% of dental hygienists, 17% of dentists) and declined to 12% for both professions in May 2021. Depression symptom rates were highest in December 2020 (17% of dental hygienists, 10% of dentists) and declined to 8% in May 2021. Controlling for gender, age, race or ethnicity, and COVID-19 community transmission level, the authors found that dentists had significantly lower odds of anxiety symptoms (adjusted odds ratio [aOR], 0.82; 95% CI, 0.70 to 0.95) and depression symptoms (aOR, 0.79; 95% CI, 0.67 to 0.93) than dental hygienists. Compared with vaccinated respondents, those who were unvaccinated but planning on getting vaccinated had significantly higher rates of anxiety (aOR, 1.71; 95% CI, 1.20 to 2.44) and depression (aOR, 1.57; 95% CI, 1.07 to 2.29) symptoms.ConclusionsDHCWs’ mental health fluctuated during the pandemic. Anxiety and depression in DHCWs were associated with demographic and professional characteristics as well as perceived risk of COVID-19.Practical ImplicationsMental health support should be made available for DHCWs.This clinical trial was registered at ClinicalTrials.gov. The registration numbers are NCT04423770 and NCT04542915.
