Acute unilateral hearing loss as an unusual presentation of cholesteatoma

BACKGROUND: Cholesteatomas are epithelial cysts that contain desquamated keratin. Patients commonly present with progressive hearing loss and a chronically discharging ear. We report an unusual presentation of the disease with an acute hearing loss suffered immediately after prolonged use of a pneumatic drill. CASE PRESENTATION: A 41 year old man with no previous history of ear problems presented with a sudden loss of hearing in his right ear immediately following the prolonged use of a pneumatic drill on concrete. The cause was found to be a fractured long process of incus which had been eroded by the presence of an attic cholesteatoma. A tympanomastoidectomy and ossiculoplasty was performed with good result. CONCLUSION: Cholesteatomas may be asymptomatic and insidious in their onset. This case illustrates the point that an indolent disease such as this may present in unusual ways and the clinician must always have a high index of suspicion combined with thorough assessment and examination of every patient

Therapy Of Endocrine Disease: Surgery In Microprolactinomas: Effectiveness And Risks Based On Contemporary Literature

Microprolactinomas are the most common pituitary adenomas. In symptomatic patients, dopamine agonists are the first-line treatment of choice; when cabergoline is used, biochemical control rates between 85 and 93% have been reported. Long-term treatment is needed in most of the cases with compliance, patient convenience, and potential adverse effects representing areas requiring attention. Based on the literature published in the past 15 years, transsphenoidal surgery can lead to normal prolactin in the postoperative period in usually 71–100% of the cases with very low postoperative complication rates. Surgical expertise is the major determinant of the outcomes, and it may be a cost-effective option in young patients with life expectancy greater than 10 years (provided it is performed by experienced surgeons at high volume centers with confirmed optimal outcomes). Larger series of patients with adequate follow-up could further validate the place of transsphenoidal surgery (particularly through the endoscopic approach for which long-term results are currently limited) in the management algorithm of patients with microprolactinoma.</jats:p

Outcome of non-functioning pituitary adenomas that regrow after primary treatment:a study from two large UK centers

Despite the major risk of regrowth of clinically nonfunctioning pituitary adenomas (CNFAs) after primary treatment, systematic data on the probability of further tumor progression and the effectiveness of management approaches are lacking.To assess the probability of further regrowth(s), predictive factors, and outcomes of management approaches in patients with CNFA diagnosed with adenoma regrowth after primary treatment.Retrospective cohort study of 237 patients with regrown CNFA managed in two UK centers.Median follow-up was 5.9 years (range, 0.4 to 37.7 years). The 5-year second regrowth rate was 35.3% (36.2% after surgery; 12.5% after radiotherapy; 12.7% after surgery combined with radiotherapy; 63.4% with monitoring). Of those managed with monitoring, 34.8% eventually were offered intervention. Type of management and sex were risk factors for second regrowth. Among those with second adenoma regrowth, the 5-year third regrowth rate was 26.4% (24.4% after surgery; 0% after radiotherapy; 0% after surgery combined with radiotherapy; 48.3% with monitoring). Overall, patients with a CNFA regrowth had a 4.4% probability of a third regrowth at 5 years and a 10.0% probability at 10 years; type of management of the first regrowth was the only risk factor. Malignant transformation was diagnosed in two patients.Patients with regrown CNFA after primary treatment continue to carry considerable risk of tumor progression, necessitating long-term follow-up. Management approach to the regrowth was the major factor determining this risk; monitoring had >60% risk of progression at 5 years, and a substantial number of patients ultimately required intervention

Intra-operative use of biological products - are we aware of their derivatives?

INTRODUCTION Global medical advances within healthcare have subsequently led to the widespread introduction of biological products such as grafts, haemostats, and sealants. Although these products have been used for many decades, this subject is frequently not discussed during the consent process and remains an area of contention. METHODS A nationwide confidential online survey was distributed to UK-based junior registrars (ST3-5), senior registrars (ST6-8), post-CCT fellows, specialist associates/staff grade doctors and consultants working in general/vascular surgery, neurosurgery, otolaryngology, oral & maxillofacial surgery and plastic surgery. RESULTS Data was collected from a total of 308 survey respondents. Biological derivatives were correctly identified in surgical products by only 25% of survey respondents, only 19% stated that they regularly consent for use of these products. Our results demonstrate that most participants in this study do not routinely consent (81%) to the intra-operative use of biological materials. An overwhelming 74% of participants agreed that further education on the intra-operative use of biological materials would be valuable. DISCUSSION This study highlights deficiencies in knowledge that results in potential compromise of the consenting process for surgical procedures. A solution to this would be for clinicians to increase their awareness via educational platforms and to incorporate an additional statement on the consent form which addresses the potential intraoperative use of biological products and what their derivatives may be. CONCLUSION Modernising the current consent process to reflect the development and use of surgical biological products will help to ensure improved patient satisfaction, fewer future legal implications as well as a better surgeon-patient relationship

Use of the medial canthal point (MCP) as a reliable anatomical landmark to the frontal sinus.

Objectives Frontal sinus surgery is considered one of the more challenging aspects of Functional Endoscopic Sinus Surgery, due to the complex variations in normal sinus anatomy but also increased morbidity due to the close proximity of critical structures such as the anterior cranial fossa and orbits. We aim to investigate the medial canthal point (MCP) as an anatomical landmark for safe frontal sinus access. Methods The MCP intranasally is identified during surgery with non-tooth forceps, with one limb just anterior to the medial canthus and the other intranasally in the same coronal plane along the skull base. This point was identified on 100 paranasal sinus computed tomography (CT) scan reconstructions. The distance between the anterior cranial fossa and MCP was measured on imaging-medial canthal point distance (MCPD). The maximal anterior-posterior (AP) distance was measured on all scans. Results The average MCPD for males was 13.0 mm (8.7-20.4 mm) and for females 12.0 mm (6.8-22.8 mm). Mean AP distance for males was 12.0 mm (4.5-20.2 mm) and for females 10.4 mm (3.8-15.9 mm). Mean distance for all 100 patients was 12.6 mm (range 7.5-22.8 mm). In all cases, the MCP was anterior to the cranial fossa. Mixed effects modelling analysis showed a significant correlation between the MCPD and AP distance ( = .006). Conclusion The MCP is a consistent anatomical landmark that can serve as an adjunct to safe frontal sinus access alongside the first olfactory fiber and CT navigation systems. However, patient selection continues to be very important, with larger well pneumatized frontal sinuses being ideal to tackle earlier in a surgeon's career. Level of evidence NA

Optimum degree of head elevation/reverse trendelenburg position for sinus surgery: Systematic review

Background: This review aims to evaluate the effect of Reverse Trendelenburg Position (RTP) on bleeding and Boezaart score and to determine the optimum degree of head elevation through a systematic review and meta-analysis.Methodology: We conducted a systematic review according to PRISMA guidelines and a literature search was performed on PubMed, Web of Science, Cochrane, Dental and Oral Science, Google scholar and Clinicaltrials.gov and included randomized controlled trials (RCTs) in English language only. We extracted all relevant data and conducted quality assessment using Cochrane risk of Bias tool (Version 2). We also performed quality assessment of the outcomes using GRADE. Meta-analysis for all the outcomes using conducted on RevMan version 5.3.Results: The search identified 629 articles and three RCTs that met our inclusion criteria. Two were included in the meta-analysis. A total of 124 patients were assessed for bleeding during sinus surgery and there was a significant reduction in total blood loss in RTP (10-15°) when compared to horizontal position by 134 ml (Mean Difference (MD): -134.23; 95% confidence interval (CI): -184.13 to -67.27). RTP also had a significant reduction in bleeding per minute by 1.07 ml/min (MD: -1.07; 95%CI: (-1.69 to -0.44), while the Boezaart score was significantly lower in the RTP group (MD: -0.69; 95%CI: -0.94 to -0.43) when compared to horizontal position.Conclusion: Though with limited evidence RTP for ESS reduces total blood loss, blood loss per minute and improves visualization. Further studies are needed to assess the actual impact and optimal degree of head elevation

A Rare Case of Fungal Rhinosinusitis Caused by Scedosporium apiopermum.

Fungal rhinosinusitis (FRS) is inflammation of the paranasal sinus mucosa due to fungal infections, which can be invasive or non-invasive. The occurrence of a sphenoid mucocele with a fungal ball is rare. We report a case of sphenoid sinus mucocele with a fungal ball caused by Scedosporium apiopermum in a 32-year-old female who presented to the Emergency Department with persistent headache not relieved on medications. The radiological images showed a mucocele with clival osteomyelitis. Urgent endoscopic examination and debridement was undertaken which demonstrated a mucocele with fungal ball. Microbiological examination confirmed it to be Scedosporium apiopermum
