Oropharyngeal cancer (OPC) is currently the most frequent human papillomavirus (HPV)–related malignancy in high-income countries. Oral HPV16 infection is the cause of HPV-related OPC in more than 90% of cases and is primarily (90%) linked to oral sex. This systematic review and meta-analysis aimed at comparing the prevalence of oral vaccine–type HPV infection in individuals vaccinated with HPV vaccines and unvaccinated controls. Three databases (MEDLINE, ScienceDirect, and the Cochrane Library), as well as other sources, were searched by 2 independent reviewers. Controlled studies testing the efficacy or effectiveness of licensed HPV vaccines were included. The primary end point was multiple oral HPV infections in one individual with low-risk and high-risk types. Secondary end point was the number of oral HPV16 infections. Six studies—2 randomized controlled trials and 4 cross-sectional studies—with a total of 15,240 participants were included in a meta-analysis, which showed that vaccinated individuals were 46% (risk ratio, 0.54; 95% confidence interval, 0.32–0.91) less likely to develop oral vaccine–type HPV infection (P = 0.02). A second meta-analysis of 4 studies (1 randomized controlled trial and 3 cross-sectional studies) and 13.285 participants showed 80% (risk ratio, 0.20; 95% confidence interval, 0.09–0.43) less likelihood of oral HPV16 infection (P < 0.0001). This study suggests that HPV vaccines can protect against oral vaccine–type HPV infection including high-risk HPV16 infection, thus reducing the incidence of HPV-related OPC. Vaccination against HPV, especially in males, who are predominantly affected by HPV-related OPC, could result in the prevention of this disease.

Objective: The purpose of this study was to evaluate the outcome of salvage total laryngectomy and identify areas for further improvement.Method: A retrospective analysis of all patients who underwent salvage total laryngectomy between January 1999 and December 2018 was performed.Results: Thirty-one patients were identified. The most common primary tumour site was the glottis (83.8 per cent). Early stage (T1–T2) disease was identified in 83.9 per cent of cases. Overall survival at 2 and 5 years post-salvage total laryngectomy was 71 per cent and 45 per cent, respectively. Disease-free survival at 2 and 5 years post-salvage total laryngectomy was 65 per cent and 42 per cent, respectively. The rate of post-salvage total laryngectomy pharyngocutaneous fistula was 29 per cent.Conclusion: More than half of patients will not survive beyond five years after salvage total laryngectomy. Regional recurrence was the most common form of failure and death. From this study, elective lateral and central neck dissection is advocated in patients with early laryngeal cancer who present with an advanced recurrence.

Sudden sensorineural hearing loss (SSHL) is a common otolaryngology emergency that significantly affects the patient’s quality of life. Although in most cases its etiology remains unknown (idiopathic SSHL), viral infections and vascular compromise constitute the most widely accepted etiopathogenic mechanisms. Specifically, occlusion of the internal auditory artery has been reported in cases of sudden deafness. Thrombotic events following the Oxford-AstraZeneca COVID-19 vaccine are rare. There have been reports of SSHL following immunization with Pfizer and Moderna COVID-19 vaccine; however, no etiologic relationship has been established between the two entities yet. We present a unique case of SSHL following the second dose of the Oxford-AstraZeneca COVID-19 vaccine. A 61-year-old female was referred to our department with a four-day history of the right-sided sense of fulness combined with almost complete hearing loss that had started two days after the second dose of Oxford-AstraZeneca COVID-19 vaccine. Pure tone audiometry showed profound right-sided sensorineural hearing loss. Magnetic resonance imaging of the brain and internal auditory canal and magnetic resonance angiography were both normal. The combination of glucocorticoids and acetylsalicylic acid leads to almost full recovery 15 days after deafness. The COVID-19 era is full of new challenges and clinical dilemmas. In our case, the addition of acetylosalicid acid to the patient’s initial treatment may have contributed to the hearing restoration; however, this fact will remain a hypothesis.

Objective: The aim of this systematic review was to analyse the complex anatomy of the extratemporal portion of the facial nerve with an accurate description of the branching patterns based on the Davis classification.Method: Medline, ScienceDirect and the Cochrane Library databases as well as other sources were searched by two independent reviewers.Results: Analysis of 21 studies with a total of 1497 cases showed that type III is the most common branching pattern accounting for 26.8 per cent of cases. The type I pattern, previously considered as the normal anatomy in most textbooks, was the fourth most common branching pattern at 16.3 per cent. The majority of specimens (96.4 per cent) were found to have a bifurcated main trunk, and only 3.2 per cent were found with a trifurcated main trunk.Conclusion: Surgeons should be aware of anatomical variations in the course of the facial nerve. An early identification of the branching pattern during surgery reduces the risk for iatrogenic facial nerve injury.
