Prehospital Blood Transfusion: A Cross-Sectional Study of Prehospital and Retrieval Medicine Services across Australia & Aotearoa-New Zealand.

BACKGROUND: The frequency and type of prehospital blood product delivery across Australia and Aotearoa-New Zealand is unknown. This study aims to describe transfusion practice across different services in the two nations, as well as identifying potential barriers to the carriage of blood products. METHODOLOGY: Prehospital and retrieval medicine services operating teams of doctors, specialist paramedics, and/or flight nurses out of specialty bases across Australia and Aotearoa-New Zealand were sent a standardized questionnaire regarding their base characteristics and their current blood transfusion practice. Bases that only performed inter-hospital transfers or search & rescue operations were excluded. Bases were queried on personnel, equipment, transport times, type and volume of blood products carried, frequency of use, and barriers to implementation for those without prehospital blood transfusion programs. RESULTS: 64 bases were identified and contacted, of which 5 were excluded and 45 of the remaining 59 (76.3%) responded. 62% (28/45) of respondents routinely carry prehospital blood products. 78.6% (22/28) carried packed red blood cells (PRBC) only, 14.3% (4/28) carried both PRBC and plasma, and 1 service (3.6%) carried whole blood. The mean number of units of blood product carried was 3.3 (SD 0.82). 2 bases (7.1%) carried fibrinogen concentrate. All services carried tranexamic acid and calcium. 734 patients received a blood transfusion in 2021, with trauma being the most common indication (552, 75.2%). Base characteristics varied significantly in staffing, vehicle platform and transfer times. The median transfer time from scene to hospital was 65 min (IQR of 40-92). Services without access to prehospital blood products identified multiple barriers to implementation, including training and supply chain. CONCLUSION: Approximately two-thirds of prehospital services operating advanced teams across Australia and Aotearoa-New Zealand carried blood products and there was wide variation both in the type and number of blood products carried by each base. Multiple barriers to the carriage of blood by all bases were reported, which have implications for service equity. Transfer times are generally long in Australia and Aotearoa-New Zealand, which may impact the generalizability of overseas research performed in prehospital systems with significantly shorter transfer times to services operating in Australia and Aotearoa-New Zealand.

Are Antibiotics Needed in Septorhinoplasty? An Evidence-Based Approach.

The use of prophylactic antibiotics in the context of septorhinoplasty (SRP) is a frequently debated topic among plastic surgeons. Most surgeons routinely use antibiotics to prevent the dreaded physical and psychological morbidity of postoperative infections, although this practice is controversial. With antimicrobial resistance becoming a global threat, however, optimizing antibiotic prescribing is essential. The current evidence would suggest that the rate of postoperative infection is low and routine antibiotic use is unnecessary in SRP surgery. Rates range from 0.5 to 2% in simple SRP surgery, majority of which are minor nasal infections which respond to oral antibiotics and do not require hospital admission. In cases of complex SRP, defined as revision cases or where grafts or implants have been utilized, infection rates can be much higher with an incidence of 7 to 11%, and as such utilization of antibiotics is reasonable. When considering the regime to be utilized, a single preoperative dose of intravenous antibiotics has the same efficacy in reducing the incident of postoperative infection as a postoperative 7-day course of oral antibiotics. In the authors' practice, all patients receive a single intravenous dose of antibiotics on induction, and in the case of utilization of a graft from a nonnasal site, this is complimented with an oral course of postoperative antibiotics. With this approach, infections rates are at the lowest range of available published literature.

Auricular reconstruction: where are we now? A critical literature review.

PURPOSE: Deformities of the external ear can affect psychosocial well-being and hearing. Current gold-standard reconstructive treatment is autologous costal cartilage grafting despite the vast morbidity profile. Tissue engineering using stem cells and 3D printing can create patient-specific reconstructed auricles with superior cosmetic outcomes and reduced morbidity. This review critically analyses recent and breakthrough research in the field of regenerative medicine for the pinna, considering gaps in current literature and suggesting further steps to identify whether this could be the new gold-standard. METHODS: A literature review was conducted. PubMed (MEDLINE) and Cochrane databases were searched using key terms regenerative medicine, tissue engineering, 3D printing, biofabrication, auricular reconstruction, auricular cartilage, chondrocyte, outer ear and pinna. Studies in which tissue-engineered auricles were implanted into animal or human subjects were included. Exclusion criteria included articles not in English and not published within the last ten years. Titles, abstracts and full texts were screened. Reference searching was conducted and significant breakthrough studies included. RESULTS: 8 studies, 6 animal and 2 human, were selected for inclusion. Strengths and weaknesses of each are discussed. Common limitations include a lack of human studies, small sample sizes and short follow-up times. CONCLUSION: Regenerative medicine holds significant potential to improve auricular reconstruction. To date there are no large multi-centred human studies in which tissue-engineered auricles have been implanted. However, recent human studies suggest promising results, raising the ever-growing possibility that tissue engineering is the future of auricular reconstruction. We aim to continue developing knowledge in this field.

Dopamine D1 receptor signalling in the lateral shell of the nucleus accumbens controls dietary fat intake in male rats.

Central dopamine signaling regulates reward-related aspects of feeding behavior, and during diet-induced obesity dopamine receptor signaling is altered. Yet, the influence of dopamine signaling on the consumption of specific dietary components remains to be elucidated. We have previously shown that 6-hydroxydopamine-mediated lesions of dopamine neuron terminals in the lateral shell of the nucleus accumbens promotes fat intake in rats fed a multi-component free-choice high-fat high-sugar (fcHFHS) diet. It is however not yet determined which dopamine receptors are responsible for this shift towards fat preference. In this study, we assess the effects of D1-or D2 receptor acute inhibition in the lateral shell of the nucleus accumbens on fcHFHS diet consumption. We report that infusion of the D1 receptor antagonist SCH2 3390, but not the D2 receptor antagonist raclopride, promotes dietary fat consumption in male Sprague Dawley rats on a fcHFHS diet during 2 h after infusion. Furthermore, anatomical analysis of infusion sites revealed that the rostral region, but not the caudal region, of the lateral shell of the nucleus accumbens is sensitive to the D1 receptor inhibition effects on fat consumption. Our data highlight a role for D1 receptors in the rostral region of the lateral shell of the nucleus accumbens to control dietary fat consumption.

Use of Novel Decellularized Cadaveric Dermis (DCELL) in Single-Stage Resection and Reconstruction of Nonmelanomatous Skin Cancer of the Head and Neck.

Reconstructive options in nonmelanomatous skin tumors of the head and neck region are limited in the frail, elderly patient group, where split skin thickness or full thickness grafts may not be a viable option. This study examines the use decellularized cadaveric dermis (DCELL), an acellular dermis product produced in the United Kingdom for the reconstruction of these skin defects. This was a single-center, prospective study of patients undergoing single stage wide local excision of nonmelanomatous skin cancer and reconstruction with decellularized dermis. Our inclusion criteria included any patient that required a curative excision but had risk factors where conventional local flap or free tissue transfer could have a potential adverse outcome. Thirty-seven wounds were treated with DCELL in 31 patients. Mean age was 81.6 years (range 61-94 years) and at the time of operation, 25 patients (80.7%) were ASA 3 or above. The scalp was the most common anatomical area operated on (n = 28, 75.7%). The overall proportion of wounds with complete closure was 89.2% (33 out of 37 wounds), with a failure rate of 10.8% (four complete graft failures). Device-related complications included one episode of crusting over the graft which resolved with topical antibiotics, and a hypertrophic scar over the wound edges. Cosmesis was satisfactory in all cases. DCELL demonstrated a very good take rate with equally satisfactory cosmetic outcomes in patients where standard reconstructive approaches may have adverse outcomes. Further research is needed to better define its role in the management of these skin cancers.

Ablation of the tail of the ventral tegmental area compensates symptoms in an experimental model of Parkinson's disease.

Parkinson's disease is a neurodegenerative disorder partly caused by the loss of the dopamine neurons of the nigrostriatal pathway. It is accompanied by motor as well as non-motor symptoms, including pain and depression. The tail of the ventral tegmental area (tVTA) or rostromedial tegmental nucleus (RMTg) is a GABAergic mesopontine structure that acts as a major inhibitory brake for the substantia nigra pars compacta (SNc) dopamine cells, thus controlling their neuronal activity and related motor functions. The present study tested the influence of suppressing this tVTA brake on motor and non-motor symptoms in a rat model of Parkinson's disease. Using behavioral approaches, we showed that male Sprague-Dawley rats with bilateral and partial 6-hydroxydopamine SNc lesion displayed motor impairments in the rotarod test, impairments that were no more present following a co-lesion of the tVTA. Using a larger set of behavioral tests, we then showed that such SNc lesion also led to non-motor symptoms, including lower body weight, lower mechanical nociceptive thresholds in the forceps test and lower thermal nociceptive thresholds in the incremented hot-plate test, and a decreased sucrose preference in a 2-bottle choice paradigm. The excitotoxic co-lesion of the tVTA led to compensation of body weight, mechanical nociceptive thresholds and anhedonia-like behavior. These findings illustrate the major influence that the tVTA exerts on the dopamine system, modulating the motor and non-motor symptoms related to a partial loss of dopamine cells.

A national survey of functional septorhinoplasty surgery performed in the United Kingdom: a clinician end-user questionnaire to assess current practice and help inform future practice.

PURPOSE: The aim of this national survey is to assess the current practice of functional septorhinoplasty (SRP) surgery in the UK and better inform future practice. METHODS: An ENT-UK approved questionnaire was sent out to all 135 consultant members of the British Society of Facial Plastic Surgery (BSFPS). Data was collected on numbers of functional SRPs performed on the NHS, use of outcome measures, psychology and photography support, antibiotic use, referral base and consenting practice. RESULTS: The response rate was 38.5%, with 52 out of 135 completed. The median number of annual SRP cases per surgeon was 40. Most surgeons (95%) used clinical photography as an outcome measure. However, 27% of the respondents use a subjective outcome measurement and 3% of them use an objective outcome measurement. Only 34% had access to psychology support and 60% receive their referrals from primary care. All surgeons counsel patients for aesthetic change, 15% mention CSF leak and 38% mention olfactory disturbance. The key comment from our respondents was to relabel the rhinoplasty procedure as a functional SRP procedure with the aim to remove it from the Procedures of Limited Clinical Value (PoLCV) list. CONCLUSION: The majority of our respondents perform a large proportion of the SRP surgeries in the UK with each of the respondents performing an average of 40 SRP surgeries per year. There is a need to recatergorise functional septorhinoplasty as a functional operation and recommend functional SRP surgery to be removed from the PoLCV list.

Dorsal Onlay with Diced Homologous Processed Rib Cartilage Grafts.

BACKGROUND: Diced cartilage wrapped in fascia or modeled with tissue sealant has successfully been used as dorsal onlay grafts in rhinoplasty. The use of autologous material introduces the risk of donor site morbidity, and sometimes availability is limited. METHODS: We present a series of nine cases that were performed using diced irradiated homologous rib cartilage as an onlay graft. RESULTS: Good functional and cosmetic outcomes were achieved in all nine patients, and no significant resorption was seen after a mean follow-up of 20 months. CONCLUSION: Homologous diced cartilage grafts are an attractive and well-tolerated alternative. The use of diced homologous material does not seem to lead to significant resorption. These results must be reproduced in larger series. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Aggressive basal cell carcinoma of the head and neck: challenges in surgical management.

With exponentially increasing numbers of basal cell carcinoma (BCC) of the head and neck region, also the locally advanced BCCs are increasing in number. These tumours are associated with aggressive biological behaviour with invasion of soft tissues, organs or bone and present with wide variation in management strategies. The objectives of the study was to describe the biological behaviour of aggressive BCCs and their clinical presentation in the head and neck region with a series of cases treated in our tertiary hospital, discuss management plans of such complex cases in terms of surgical planning and reconstruction. A series of five cases of aggressive BCC in the head and neck region with involvement of organs such as nose, orbit, temporal bone, facial nerve, paranasal sinuses and mandible was studied. Locally advanced, aggressive BCC should be evaluated and treated as head and neck tumours. Multidisciplinary team (MDT) discussion is advisable wherein the strategies on surgical excision, reconstruction options, facial nerve rehabilitation, indications for prosthesis and further adjuvant treatment such as radiotherapy and chemotherapy are carefully planned.

Factors predictive of outcome following primary total laryngectomy for advanced squamous cell carcinoma.

The increasing use of primary chemoradiation (CRT) for laryngeal squamous cell carcinoma (SCC) means that historical surgical data sets are not representative of the modern laryngectomy patient. We analyse a contemporary total laryngectomy (TL) cohort to identify factors predictive of outcome. This is a retrospective consecutive case note review in a UK tertiary referral centre. Demographic, staging, treatment and outcome data were collected. Oncological outcomes are expressed using the Kaplan-Meier method. The log-rank test was used for univariate analysis and cox regression for multivariate analysis. Sixty consecutive patients between 2003 and 2010 underwent primary TL, 28 including partial pharyngectomy. Median age was 61 years and mean follow-up was 24 months (1-78 months). Thirty six patients died during the study period, 24 of their disease. Of the disease-specific deaths, two occurred peri-operatively, four from local, two from regional and 18 from distant disease [two patients had simultaneous local and distant recurrence (DR)]. Five-year overall survival, disease-specific survival, loco-regional recurrence-free survival and distant recurrence-free survival (DRFS) were 36, 51, 87, 62 %, respectively. Of 17 parameters analysed, pN-stage, extra-capsular spread, a non-cohesive tumour front, thyroid infiltration and involvement of level 6 were significant predictors of disease-specific survival (DSS) on univariate analysis. pN > 1 and the presence of adverse histological features were found to be independent predictors of DSS and DRFS on multivariate analysis. Neither was significantly associated with loco-regional recurrence-free survival. Around half of patients who undergo TL for stage IV SCC will die of disease within 5 years, with most deaths attributable to DR. Surgery provides excellent loco-regional control but patients, especially those with advanced nodal disease and/or adverse histological features, should be thoroughly screened for occult distant disease. Level of evidence 4.

Pre-operative tracheostomy does not impact on stomal recurrence and overall survival in patients undergoing primary laryngectomy.

Pre-operative tracheostomy (POT) to secure a critical airway up to several weeks before definitive laryngectomy in patients with laryngeal cancer has been proposed as a risk factor for poor oncologic outcome. Few modern papers, however, examine this question. The aim of this study is therefore to determine whether POT affects oncologic outcome with an emphasis on stomal/peristomal recurrence. This is a retrospective case note review of 60 consecutive patients undergoing curative primary total laryngectomy (TL) for advanced laryngeal squamous cell carcinoma (SCC). Demographic, staging, treatment and outcome data were collected. 27/60 (45 %) patients had POT and 33/60 did not. No patient underwent laser debulking. Median age was 62 years (39-90 years) and median follow-up of survivors was 31 months. 5-year overall survival (OS), disease-specific survival (DSS) and local recurrence-free survival (LRFS) of patients undergoing POT versus no POT was 28 versus 39 % (p = 0.947), 55 versus 46 % (p = 0.201) and 96 versus 88 % (p = 0.324) respectively. No statistically significant difference in OS, DSS and LRFS was found between patients undergoing POT and those not. Despite the relatively small case series, this evidence should reassure surgeons without the ability to perform trans-oral debulking that they should not hesitate to perform tracheostomy on a patient with airway obstruction due to laryngeal cancer. Appropriate definitive treatment meant that POT was not a risk factor for poor oncological outcome in our series.

Does wearing a surgical mask influence face touching by healthcare workers? A retrospective cohort study.

OBJECTIVE: At the start of the COVID-19 pandemic, healthcare workers (HCW) in our ED were advised against and actively discouraged from wearing masks when not seeing respiratory patients, as mask wearing was thought to increase the risk of droplet transmission by face touching. The primary objective of the present study was to determine whether HCW using face masks were more or less likely to touch their faces than those not wearing masks. METHODS: We analysed six randomly selected hours of closed circuit television footage from our staff base. Face touches were recorded electronically by trained researchers. Generalised linear mixed models were used to compare the frequency and duration of face touches with and without face masks, controlling for individual clusters, adjusting for time of footage, duration on screen and staff role. RESULTS: Data were collected from 187 HCW. Masks were worn in 231 (36%) of 642 screen sessions. Wearing a mask did not significantly change the odds of face touching (odds ratio 0.55, 95% confidence interval [CI] 0.30-1.01, P = 0.055) or duration of face touch (mean difference -1.45 s, 95% CI -8.84, 5.99, P = 0.71). For mucosal areas, a significant reduction in the odds of face touching was observed for mask wearers (odds ratio 0.21, 95% CI 0.11-0.43, P < 0.001) and on the frequency of mucosal touches (rate ratio 0.45, 95% CI 0.29-0.69, P < 0.001). CONCLUSIONS: Mask wearing did not change face touching or the duration of face touches. However, significantly fewer mucosal touches were observed when wearing a mask, which may help to reduce nosocomial droplet transmission of viruses.

Post-operative wound infection in salvage laryngectomy: does antibiotic prophylaxis have an impact?

Salvage laryngectomy carries a high risk of post-operative infection with reported rates of 40-61%. The purpose of this study was to analyse infections in our own patients and review the potential impact of our current antibiotic prophylaxis (AP). A retrospective analysis of infection in 26 consecutive patients between 2000 and 2010 undergoing salvage total laryngectomy (SL) following recurrent laryngeal cancer after failed radiotherapy or chemo-radiation was undertaken. The antibiotic prophylaxis was intravenous teicoplanin, cefuroxime and metronidazole at induction and for the following 24 h. Infection was defined by Tabet and Johnson's grade 5, categorized as pharyngocutaneous fistula. Fifteen patients (58%) developed a post-operative wound infection, which occurred on average at 12 days after surgery. Univariate analysis demonstrated three risk variables that had a significant correlation with infection: alcohol consumption (p = 0.01), cN stage of tumour (p < 0.01), and pre-operative albumin levels <3.2 g/L (p = 0.012). There was a trend, though not significant, for increased infection in patients with high or low BMIs. The most common organisms isolated from clinical samples from infected patients were methicillin-resistant Staphylococcus aureus MRSA (43%), Pseudomonas aeruginosa (36%), Serratia marcescens, Proteus mirabilis and Enterococcus faecalis (7% each). All these organisms are typical hospital-acquired pathogens. Pseudomonas and Serratia were not covered by the prophylactic regime we used. The current antibiotic regime following SL is inadequate as the rate of infection is high. It would therefore seem logical to trial a separate antibiotic protocol of AP for patients undergoing SL that would include an extended course of antibiotics after the standard prophylaxis. In addition, infection rates may also be reduced by improving the metabolic state of patients pre-operatively by multi-disciplinary action. Steps should also be taken to reduce cross-infection with nosocomial pathogens in these patients. Other aspects of surgical management should be also taken in consideration.

Tubercular Tenosynovitis Mimicking a Large Ganglion Cyst.

Introduction: Tubercular tenosynovitis of the wrist and hand, although rare, presents a diagnostic dilemma primarily due to its non-specific clinical presentation, insidious course, and the large number of differentials that mimic it. When the diagnosis is late or delayed, significant bone and tendon complications occur. Large progressive swelling around the wrist in TB endemic countries should raise an early suspicion of being of tubercular etiology and should be high on the list of differential diagnoses. Case Report: A 48-year-old female presented with a large progressive swelling on the volar aspect of the left wrist and palm for 7 months, associated with increasing pain, stiffness, limited wrist range of movements, and weakened grip strength. Magnetic resonance imaging (MRI) revealed synovitis and fluid within flexor tendon synovial sheaths. The patient underwent an excision of the mass in toto and the cut section revealed an irregularly thickened wall with rice bodies within. Histopathological examination was indicative of a large ganglion cyst. GeneXpert MTB/RIF assay detected Mycobacterium tuberculosis. Despite histopathology being inconclusive, a diagnosis of TTS was considered due to the patient's clinical presentation, MRI, and operative findings. The patient was started on an antitubercular drug regimen for a 1-year duration. The patient regained a complete range of movements of fingers and wrist and normal grip strength at the 3rd month follow-up. Conclusion: TTS is a challenging diagnosis entity. The diagnostic confirmation was achieved either by histopathology or detection of the organism either by culture or GeneXpert MTB/RIF assay. When the diagnosis is unsupported, drug therapy can be initiated empirically on strong suspicion of tuberculosis, especially in TB endemic areas.

Role of the striatal dopamine, GABA and opioid systems in mediating feeding and fat intake.

Food intake, which is a highly reinforcing behavior, provides nutrients required for survival in all animals. However, when fat and sugar consumption goes beyond the daily needs, it can favor obesity. The prevalence and severity of this health problem has been increasing with time. Besides covering nutrient and energy needs, food and in particular its highly palatable components, such as fats, also induce feelings of joy and pleasure. Experimental evidence supports a role of the striatal complex and of the mesolimbic dopamine system in both feeding and food-related reward processing, with the nucleus accumbens as a key target for reward or reinforcing-associated signaling during food intake behavior. In this review, we provide insights concerning the impact of feeding, including fat intake, on different types of receptors and neurotransmitters present in the striatal complex. Reciprocally, we also cover the evidence for a modulation of palatable food intake by different neurochemical systems in the striatal complex and in particular the nucleus accumbens, with a focus on dopamine, GABA and the opioid system.

Midbrain and Lateral Nucleus Accumbens Dopamine Depletion Affects Free-choice High-fat high-sugar Diet Preference in Male Rats.

Dopamine influences food intake behavior. Reciprocally, food intake, especially of palatable dietary items, can modulate dopamine-related brain circuitries. Among these reciprocal impacts, it has been observed that an increased intake of dietary fat results in blunted dopamine signaling and, to compensate this lowered dopamine function, caloric intake may subsequently increase. To determine how dopamine regulates food preference we performed 6-hydroxydopamine (6-OHDA) lesions, depleting dopamine in specific brain regions in male Sprague Dawley rats. Food preference was assessed by providing the rats with free choice access to control diet, fat, 20% sucrose and tap water. Rats with midbrain lesions targeting the substantia nigra (which is also a model of Parkinson's disease) consumed fewer calories, as reflected by a decrease in control diet intake, but they surprisingly displayed an increase in fat intake, without change in the sucrose solution intake compared to sham animals. To determine which of the midbrain dopamine projections may contribute to this effect, we next compared the impact of 6-OHDA lesions of terminal fields, targeting the dorsal striatum, the lateral nucleus accumbens and the medial nucleus accumbens. We found that 6-OHDA lesion of the lateral nucleus accumbens, but not of the dorsal striatum or the medial nucleus accumbens, led to increased fat intake. These findings indicate a role for lateral nucleus accumbens dopamine in regulating food preference, in particular the intake of fat.

Frey's Syndrome: A Review of Aetiology and Treatment.

First described by Polish Neurologist Lucja Frey in 1923, Frey's syndrome (FS), or auriculotemporal syndrome, is a rare condition characterised by gustatory sweating, typically encountered as sequelae following invasive head and neck surgery. The pathophysiology of FS can be described by aberrant reinnervation of postganglionic parasympathetic neurons to the surrounding denervated sweat glands and cutaneous blood vessels. Multiple invasive procedures have been associated with FS ranging from salivary gland surgery to burn reconstruction and thoracoscopic sympathectomies. Rarely, FS can be secondary to trauma or non-surgical aetiologies, including diabetes and infection. Physical symptoms vary based on the severity and surface area affected by FS and range from mild symptoms to severe psychosocial morbidity for patients. Surgeons operating in the head and neck, including otolaryngologists, maxillofacial surgeons, and plastic surgeons, should be aware of this potential complication and be up to date with diagnosis and treatment strategies for FS. This review article summarises the literature relating to FS focusing on its aetiologies, symptomatology, prevention, and available treatments, aiming to provide an up-to-date review of this condition for surgeons operating in the head and neck region. Although various treatment options have been suggested, these are often limited to topical agents that require life-long administration for symptom control. Further research is recommended to identify the optimal treatment for this condition and the role of surgery as a treatment for severe or refractory cases.

Update on the role of emerging stem cell technology in head and neck medicine.

Head and neck surgery is a broad discipline that involves the management of complex conditions such as burns, skin cancer, head and neck cancer, congenital abnormalities, and facial rejuvenation. For patients with cancer, surgery, radiotherapy, and chemotherapy are often the main modes of treatment. Many patients require follow-up reconstructive surgery, and the use of stem cells offers novel treatments that could aid recovery. Laryngeal, tracheal, and neuronal tissues are frequently damaged by surgery in the head and neck and these tissues have little intrinsic regenerative ability. Pluripotent embryonic stem cells retain the ability to differentiate into a wide variety of cells meaning that large tissue defects can be reduced by stimulating new cell growth. Research has demonstrated potential benefits of using stem cells in facial rejuvenation procedures and the management of burns sequelae. The advancements made in the use of adult progenitor stem cells as a possible source for pluripotent stem cells (induced pluripotent stem cells) mean that ethical considerations around the use of embryological tissue can be minimized, allowing for more research to take place. Currently, the evidence base for the use of stem cells in head and neck surgery is limited, but it has now been proven that stem cells can act as a source for lost or damaged tissue in the head and neck. With continuous advancements being made in the fields of tissue engineering, it is likely that stem cells will play a major role in head and neck surgery in the future.
