Managing the risk from children's travel cups.

INTRODUCTION: UK national newspapers have reported cases of children (and adults) who have got their tongue trapped in a Disney travel mug lid, causing extreme distress to the patients, their parents and ED staff. Potential risks include oral endotracheal intubation necessitating emergency tracheostomy to secure the airway, tongue necrosis and dental trauma. Although Disney has withdrawn their original mug from the global market, the same dangers can occur with other internationally available brands. Our aim was to design, test and present an alternative lid. METHODS AND MATERIALS: We designed an alternative lid to fit onto the original Disney mug; our addition of two parallel bars prevented tongue protrusion into the lid. Prototypes of the original and new lids were three-dimensional printed for testing. A tongue substitute was developed and a representative 0.2 bar suction force was generated. The bottle was mounted in a material test machine, attached to the load cell fixture. Four samples each for the existing and new design were tested. The data were analysed by a custom Matlab script to extract the maximum force required to remove the tongues from the cup. RESULTS: The new design resulted in a significant (p=0.0286, Mann-Whitney U) reduction in pullout force. For the existing design, the median pullout force was 4.64 N (minimum 3.86 N, maximum 4.91 N), while it was 2.37 N (minimum 2.20 N, maximum 2.53 N) for the new design. Trauma to the materials used with the original lid design was evident but not observed with our design. CONCLUSION: Our lid appears to offer a safer design that can avoid injuries. However, absolute safety remains unproved, as testing did not account for other body parts which may get trapped in the lid, nor did we test a range of tongue substitute sizes, and laboratory testing only was completed.

Cleft Repair in Adults: A Report on a Case Series.

Speech defects and facial appearance due to untreated cleft lip and/or palate in the elderly population have associated life-long impacts on the quality of life for these patients. Treatment and rehabilitation in this patient group can be extensive and the problems not easily corrected. We report the outcomes of surgical repair of cleft in a series of elderly patients with unrepaired cleft lip and/or palate. Our results confirm an improvement in speech, quality of life and aesthetic outcomes after surgical repair in these patients. With this in mind, we advise cleft teams to consider surgical repair of untreated cleft lip and/or palate in the elderly population.

Spindle cell haemangioma of the tongue.

BACKGROUND: Spindle cell hemangioma (SCH) is an uncommon benign vascular tumor that rarely occurs in the mouth. METHODS AND RESULTS: We present an SCH arising in the tongue of a 52-year-old otherwise healthy woman. SCH should be considered in the differential diagnosis of vascular tumors in the oral cavity and not misinterpreted as a more aggressive vascular tumor. We describe the clinical presentation, investigation, differential diagnosis and management of this condition and a literature search showing published case reports. CONCLUSION: Although SCH rarely presents in the oral cavity it needs to be considered in the differential diagnosis of oral cavity tumors.

Retraction of the Soft Palate During a Modified Hynes Pharyngoplasty: A Technical Note.

Surgical management of velopharyngeal insufficiency by construction of sphincter pharyngoplasty is well described in the medical literature. Hynes advocated splitting an intact soft palate when it would be helpful for better exposure of the posterior pharyngeal wall for flap inset. We describe a modification to the Hynes pharyngoplasty whereby the soft palate is retracted upward, giving the operator unrestricted surgical access to the salpingopharyngeus muscles and their overlying mucosa. This allows the surgeon to raise and inset the flaps, as described by Hynes, without the need to divide the soft palate. The retraction catheters avoid the need for splitting a soft palate, which has been optimized by either a Furlow or soft palate re-repair in the past, avoiding unnecessary compromise of the integrity and architecture of the soft palate.

Oral focal mucinosis of the palate: a rare disease entity.

Oral focal mucinosis (OFM) is an extremely rare, benign oral soft tissue condition; less than 10 documented cases have been reported in the literature in patients under 18 years old. OFM has an unknown aetiology and predominantly presents in the fourth and fifth decades. The pathogenesis of OFM may be due to fibroblast overproduction of hyaluronic acid. Clinically, it remains almost impossible to diagnose definitively, due to its lack of pathognomonic features, therefore such lesions may have multiple differential diagnoses and histological analysis is essential to confirm OFM. We present an unusual presentation of OFM in a 14-year-old female patient. Following excision, focal myxoid degeneration of the connective tissue was apparent. This case highlights this rare condition for consideration in differential diagnosis of clinically similar lesions.

Patients' perception of using a smartphone light source in the clinical environment.

Introduction A satisfactory light source is of paramount importance during an oral head and neck examination. It has become common practice for the light source on a smartphone to be used during inpatient intra-oral examination. We determined if patients identified the use of a smartphone as a light source, during head and neck examinations, as unprofessional.Methods and materials A clinical photograph illustrating professional errors was presented to patients as a pilot survey (n = 10); a smartphone camera flash being used as a light source was featured. Patients were then asked which aspects they considered unprofessional. Following staff training and improvements to the survey wording, the same photo was presented to patients (n = 150) as the main study.Results Of the patients surveyed, 97% considered the use of a smartphone in the staged clinical photograph as unprofessional. They also noted: a clinician sitting on the bed (88%), clinicians not wearing gloves (81%), lack of privacy/curtain not drawn (62%), long hair not tied back (50%), a clinician's name badge not visible (23%), clinician bare below the elbows (15%) and clinician not wearing a tie (12%).Conclusions This is the first piece of research into the use of a smartphone light source within clinical examination. The use of a smart phone light source during clinical examination was the most reported 'error' and was recognised more than a clinician not wearing gloves. Eighty-five percent of patients considered the use of a smartphone light source unprofessional. Authors, therefore, do not advocate the use of a smartphone light source in the clinical care of patients.

Review of orthognathic surgery and related papers published in the British Journal of Oral and Maxillofacial Surgery 2011-2012.

This review summarises all orthognathic and related papers published between January 2011 and December 2012 in the British Journal of Oral and Maxillofacial Surgery (BJOMS). A total of 36 articles were published, a high proportion of which (78%) were full-length papers. The remainder consisted of short communications and technical notes. The topics included operative planning and postoperative outcomes, and there was a strong focus on distraction osteogenesis. There were fewer orthognathic articles published in BJOMS than articles on other subspecialties such as trauma or head and neck oncology. Only 8 (29%) of the full-length articles were prospective studies or randomised trials, which highlights a need for well-designed clinical studies in orthognathic research.

Salivary pooling: is it specific to particular regions in oral submucous fibrosis?

Despite extensive research, the pathophysiology of oral submucous fibrosis (OSMF), a premalignant condition that primarily affects the mucosa, is still unclear, although the chewing of areca nut is known to be the primary cause. While a clear association exists between areca nut and OSMF, very little has been published on the reason for its sporadic incidence in the mouth. Many authors have suggested the site where quid is habitually placed, but this fails to explain multiple sites in those who chew on one side. We hypothesised that the pattern of salivary pooling might affect the distribution of OSMF by carrying the chemicals responsible for mucosal damage. In our study of 174 patients, we evaluated the sites where quid was habitually placed and the areas of salivary pooling, and their association with the incidence of OSMF. Most chewers (136/174, 78%) placed the quid in the buccal vestibule, although other sites were also used including the vestibule of the lip, tongue, and floor of the mouth. The standardised residuals suggested significant associations (p<0.001) between salivary pooling and OSMF, and indicated that salivary pooling affects the mucosal surfaces where it occurs. Our results show that the quid is not the only cause of OSMF. Salivary pooling also has an important role and provides a possible mechanism for the sporadic incidence of the condition. To our knowledge this is the first study to evaluate salivary pooling as a contributory factor in OSMF, and it may help to explain the pattern of distribution. Further work is needed in this area to understand the association more fully.

Experience of head and neck theatre staff and attitudes to human factors using an aviation-based analysis and classification system--a pilot survey.

The role that human factors have in contributing to air crashes is well known and is included as an essential part of training. Awareness of human factors in surgery is increasingly being recognised but surprisingly few papers have come from head and neck specialties. We circulated a questionnaire on human factors based on an aviation model to 140 head and neck medical and ancillary staff who work in operating theatres in 3 large UK hospitals. Most positive responses were found in the consultant group followed by trainee doctors and support staff. A significant difference was found in the subcategories of Unsafe Supervision (p=0.002) and Preconditions to Unsafe Acts (p=0.001). This work will help to identify multi-system deficiencies that can be corrected, and highlights aspects that may yield the greatest reduction in surgical errors.

How do I manage an acute injury to the facial nerve?

Paralysis of the facial nerve is a cause of considerable functional and aesthetic disfigurement. Damage to the upper trunk can result in eye complications with the risk of exposure keratitis. Numerous factors influence the therapeutic strategy: the cause of the injury, the time elapsed since injury, functional impairment, and the likelihood of recovery. We discuss the management of an acute injury to the facial nerve and focus on the surgical options.

Role of drinking water copper in pathogenesis of oral submucous fibrosis: a prospective case control study.

Although oral submucous fibrosis (OSMF) is thought to be multifactorial in origin, the chewing of areca nut is thought to be the main cause. Alkaloids and tannins in areca nut are responsible for fibrosis, but recent evidence has suggested that copper ions are also an important mediator, and in a small pilot study we recently found that OSMF was significantly associated with a raised concentration of copper in drinking water. We have further investigated this association in a heterogeneous population in Hyderabad-Karnataka, India, a region with a high incidence of the condition. We evaluated 3 groups, each of 100 patients: those with OSMF who chewed gutkha, those who chewed gutkha but did not have OSMF, and healthy controls who did not chew gutkha. The difference between the groups in the mean concentration of copper in water measured by atomic absorption spectrometry was significant (p<0.001). There were also significant differences between the groups in mean concentrations of serum copper, salivary copper, and ceruloplasmin (p<0.001). Our results confirm that copper in drinking water contributes to the pathogenesis of OSMF, but ingestion of copper is unlikely to be the sole cause.

Allergic reaction to a red plastic allergy alert patient identification bracelet: implications for surgical patient safety.

We present a case of allergy to a hospital thermally-printed red plastic allergy alert bracelet in a 48 year old lady admitted to the day surgery unit. Two hours postoperatively, an intensely itchy area of erythema and oedema was seen extending from her left wrist distally to the fingers. The bracelet was removed and the rash resolved overnight without further complication. A diagnosis of contact dermatitis was made, secondary to exposure to an agent within the bracelet. We discuss the safety implications for surgical patients unable to wear an identification bracelet and the steps that may be taken to minimise the risk of harm from misidentification. We believe this to be the first documented case of an allergy to a patient identification bracelet in the medical literature.

Supraclavicular metastases from distant primaries: what is the role of the head and neck surgeon?

Suspicious malignant supraclavicular lymphadenopathy provides a challenge for diagnosis and treatment. The wide variety of primary tumours that metastasise to this region should alert the clinician to look beyond the head and neck, particularly if it is the only site in the neck with suspected disease. As metastatic spread to these nodes from primaries not in the head and neck often indicates wide spread disease, neck dissection is controversial. In this article we review the lymphatic anatomy and discuss the investigation of supraclavicular lymphadenopathy. We discuss the evidence for the management of the neck in patients with subclavicular primary cancers (excluding lymphoma and melanoma) and the role of neck dissection.

Posterior auricular nerve found anterior to the cartilage of the external auditory meatus--a previously unreported variant.

We describe a previously unreported anatomical variant of the posterior auricular nerve found during parotidectomy, and discuss its clinical implications.

Lymphatic malformations of the head and neck-current concepts in management.

Lymphatic malformations of the head and neck, also known as lymphangiomas or cystic hygromas, are a diverse group of lesions. They can be small and superficial or large and extensive, and management can be a challenge. Surgically they can be difficult to remove completely because of their poorly defined borders and the potential for damaging neighbouring structures. We review the dilemmas posed in diagnosis and treatment, and discuss the contemporary management of these interesting entities including sclerotherapy, which is gaining popularity.

Multiple Individual Audit Outcome Web--a novel tool to evaluate patient outcomes.

Multiple Individual Audit Outcome Web (MIAOW) is a pictorial representation of outcomes, which is used widely in industry, finance, and sports, but not, to the best of our knowledge, in our specialty. It was developed to display multiple audit outcomes for patients in cleft surgery and we show its use in that area, but equally it could be applied to other areas such as orthognathic surgery, and head and neck oncology. We report how it can be used to display surgical outcomes.

Full length articles published in BJOMS during 2010-11--an analysis by sub-specialty and study type.

Full length articles such as prospective and retrospective studies, case series, laboratory-based research and reviews form the majority of papers published in the British Journal of Oral and Maxillofacial Surgery (BJOMS). We were interested to evaluate the breakdown of these types of articles both by sub-specialty and the type of study as well as the proportion that are written by UK colleagues compared to overseas authors over a 2 year period (2010-11). A total of 191 full length articles across all sub-specialties of our discipline were published, with 107 papers (56%) coming from UK authors. There were proportionately more oncology papers arising from the UK than overseas (60 and 30% of total respectively) while the opposite was found for cleft/deformity studies (10% and 22%). There was only one laboratory-based study published from the UK compared with 27 papers from overseas. The number of quality papers being submitted to the Journal continues to increase, and the type of article being published between UK and overseas probably reflects different practices and case-loads amongst colleagues. The relatively few UK laboratory based studies published in BJOMS compared to overseas authors are most likely due to authors seeking the most prestigious journals possible for their work.

Performing to a world class standard under pressure--can we learn lessons from the Olympians?

With the 2012 Olympics being held in London, we explored pre-requisites for success in sport, and the comparative efficacy of employing these when performing under intense pressure in the clinical setting. We asked members of the Great Britain Olympic rowing team and OMFS surgeons to complete a validated questionnaire on how they performed under pressure. 89 questionnaires were completed by 43 surgeons and 46 rowers (81% response). We compared the results in terms of mental toughness and technical skill. The importance of training to be a winner was evident in athletes. While emphasising the multidimensional nature of talent, we recognise the essential role of psychology in the ability of individuals to fulfil their sporting potential. We discuss the possible implications for surgeons.

Squamous cell carcinoma arising in dentigerous cysts.

We present two cases of squamous cell carcinoma (SCC) arising in dentigerous cysts. Malignant transformation in dentigerous cysts is rare giving rise to diagnostic difficulties. We propose imaging at an early stage to reduce delays in diagnosis.
