Abstract
Study Design Systematic review of the literature. Objective The goal of this study is to review the current literature on the trends in management of laryngeal fractures following trauma. Methods Independent searches of the PubMed and MEDLINE databases were performed. Articles from the period of 1963 to 2020 were collected. All studies which described laryngeal fractures using the Boolean method and relevant search term combinations, including "Laryngeal", "Fracture", "Operative", and "Management" were collected. Results A total of 588 relevant unique articles were identified for analysis. Of these, 24 articles were deemed appropriate for inclusion in the literature review. Due to variability in study design and outcome measures, formal synthesis of data in the form of a meta-analysis was not possible. Conclusions Laryngeal fractures are rare traumatic injuries that require early identification and evaluation with complex management options. This comprehensive review aims to highlight the breadth of the topic with regard to presentation and clinical management. Though there remains no clear best practice for laryngeal fracture management, we review trends in clinical practice throughout the literature.

Stewart ME, Erath BD. Investigating blunt force trauma to the larynx: The role of inferior-superior vocal fold displacement on phonation. J Biomech 2021; 121:110377. [PMID: 33819698 DOI: 10.1016/j.jbiomech.2021.110377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 02/24/2021] [Accepted: 03/01/2021] [Indexed: 11/26/2022]
Abstract
Blunt force trauma to the larynx, which may result from motor vehicle collisions, sports activities, etc., can cause significant damage, often leading to displaced fractures of the laryngeal cartilages, thereby disrupting vocal function. Current surgical interventions primarily focus on airway restoration to stabilize the patient, with restoration of vocal function usually being a secondary consideration. Due to laryngeal fracture, asymmetric vertical misalignment of the left or right vocal fold (VF) in the inferior-superior direction often occurs. This affects VF closure and can lead to a weak, breathy voice requiring increased vocal effort. It is unclear, however, how much vertical VF misalignment can be tolerated before voice quality degrades significantly. To address this need, the influence of inferior-superior VF displacement on phonation is investigated in 1.0mm increments using synthetic, self-oscillating VF models in a physiologically-representative facility. Acoustic (SPL, frequency, H1-H2, jitter, and shimmer), kinematic (amplitude and phase differences), and aerodynamic parameters (flow rate and subglottal pressure) are investigated as a function of inferior-superior vertical displacement. Significant findings include that once the inferior-superior medial length of the VF is surpassed, sustained phonation degrades precipitously, becoming severely pathological. If laryngeal reconstruction approaches can ensure VF contact is maintained during phonation (i.e., vertical displacement doesn't surpass VF medial length), improved vocal outcomes are expected.

Abstract
OBJECTIVE Systematic review of blunt pediatric laryngeal and tracheal trauma and development of proposed evaluation and management strategy. STUDY DESIGN Systematic review and proposed clinical consideration algorithm. DATA SOURCES PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. REVIEW METHODS A medical librarian was utilized. RESULTS 329 titles and abstracts were identified, and 50 reports were included. A total of 66 children were identified, with a majority of males (76.1%). Average age was 9.5±4.4years [range 2-17]. CT was employed in 66.7% of cases. False negative CT occurred in 29.5% of cases. Treatment consisted of observation (9.1%), endoscopy alone (31.8%), endoscopic repair (7.6%), and open neck exploration with repair/open reduction internal fixation (ORIF) (51.5%). Tracheotomy was utilized in 33.3% of the cases. Mortality was rare, with only one (1.5%) reported and occurred within one hour after presentation. CONCLUSIONS Significant deviation and variation from recommended previously proposed management algorithms exists in reported cases. Awareness of the natural clinical history, potential for severe morbidity or mortality, and associated complications are extremely important. CT and fiberoptic, bedside laryngoscopy may not play a significant role but may add to clinical evaluation prior to operative intervention. If employed, care must be taken to not create an unstable clinical scenario. Operative endoscopy is recommended in cases with positive physical examination findings, and treatment tailored to extent of injury. LEVEL OF EVIDENCE IV. TYPE OF STUDY Systematic review.

Abstract
Laryngeal trauma is an uncommon but life threatening injury which is uncommon in British practice. It often occurs as part of a multiple injury. Major laryngeal injury may cause catastrophic airway compromise and death. Minor laryngeal injuries may be missed as more severe injuries supercede the management of the larynx. This may have adverse long-term sequlae. This article presents the initial assess ment and management of the patient with laryngeal trauma. The various controversies are discussed with reference to the literature available. The surgical approaches to the larynx are described.

Abstract
OBJECTIVES/HYPOTHESIS To discuss the incidence, diagnosis, laryngeal findings, and management of arytenoid dislocation as a separate entity from vocal fold paralysis. STUDY DESIGN Literature review. METHODS A contemporary review of the literature was performed by searching the terms arytenoid cartilage dislocation and subluxation in various combinations. Articles were analyzed and selected based on relevance and content. RESULTS Arytenoid dislocation is described as an uncommon laryngeal finding associated with intubation or blunt laryngeal trauma. The majority of recent publications are case reports or small case series. Diagnosis of arytenoid dislocation with flexible laryngoscopy, helical computed tomography, videostroboscopy, and laryngeal electromyography is recommended. In most reported cases, diagnosis has been made based on the position of the arytenoid at laryngoscopy. Reduction and repositioning of the arytenoid cartilage is reported with limited success noted with delayed diagnosis. Speech therapy may also be a beneficial treatment option. CONCLUSIONS Although arytenoid dislocation is reported in the literature, the body of available evidence fails to sufficiently differentiate it as a separate entity from unilateral vocal fold paralysis. Flexible laryngoscopy is inadequate as a standalone procedure to distinguish arytenoid dislocation from laryngeal nerve injury.

Abstract
The larynx and surrounding soft tissues are vulnerable to injury during athletics despite protective equipment and rule modifications. Laryngeal injuries are uncommon but potentially fatal conditions that pose risks to the voice, airway, and esophagus of athletes who sustain blunt or penetrating neck trauma. Common symptoms and signs of laryngeal trauma include hoarseness, dyspnea, hemoptysis, dysphonia, respiratory distress, anterior neck tenderness, subcutaneous emphysema, and loss of normal laryngeal architecture. Diagnostic evaluation includes plain radiographs, computed tomography, and fibroscopic endoscopy. Most athletes with laryngeal injuries will require surgical treatment to restore normal regional anatomy and vocal quality. Less severe injuries may be treated with close observation, serial endoscopy, medications, and vocal rest.

Abstract
CONCLUSION We recommend early surgical exploration and fixation for patients with dislocated or comminuted laryngeal fractures to avoid long-term voice complications. One-third of 33 fracture patients rated their voice after the fracture had healed as fair but altered. OBJECTIVES To examine the indications for and the outcome of surgical management in patients with laryngeal fractures. PATIENTS AND METHODS The study was carried out in a tertiary care referral university hospital and was a retrospective study of case series. Thirty-three consecutive patients, aged 14-84 years, presented with various types of laryngeal fractures. Patients were staged according to the type of the fracture and surgical correction was performed when indicated. Voice outcome was documented and patients with subjectively suboptimal result were further evaluated by phoniatric specialist. RESULTS In all, 32 of 33 laryngeal fracture patients had blunt trauma and the main causative factors were sport injuries (39%) and physical assault (33%). All of the 33 laryngeal fracture patients had a good airway outcome. The subjective voice outcome was good for 20 (61%) and fair for 13 (39%) patients. The mean follow-up time was 39.5 months (range 2-114 months). In phoniatric evaluation most (six of eight) patients with fair voice outcome could not produce high pitched voices because of inability to stretch the vocal folds.

Abstract
SUMMARY Arytenoid cartilage dislocation is an infrequently diagnosed cause of vocal fold immobility. Seventy-four cases have been reported in the literature to date. Intubation is the most common origin, followed by external laryngeal trauma. Decreased volume and breathiness are the most common presenting symptoms. We report on 63 patients with arytenoid cartilage dislocation treated by the senior author (RTS) since 1983. Significantly more posterior than anterior dislocations were represented. Although reestablishing joint mobility is difficult, endoscopic reduction should be considered to align the heights of the vocal processes. This process may result in significant voice improvement even long after the dislocation. Strobovideolaryngoscopy, laryngeal electromyography, and laryngeal computed tomography (CT) imaging are helpful in the evaluation of patients with vocal fold immobility to help distinguish arytenoid cartilage dislocation from vocal fold paralysis. Familiarity with signs and symptoms of arytenoid cartilage dislocation and current treatment techniques improves the chances for optimal therapeutic results.

Abstract
Laryngotracheal trauma may result in lifelong complications or even death if diagnosis or treatment is delayed. Emergency room physicians, trauma surgeons, anesthesiologists, and especially otolaryngologists should maintain a high level of awareness of and suspicion for laryngotracheal trauma whenever a patient presents with multiple trauma in general or with cervical trauma in particular. Although there is some controversy regarding care, treatment in experienced hands will usually result in a favorable outcome. In this article, we review and update the diagnosis and management of acute external laryngotracheal trauma.
