Objective: The most widely used diagnostic technique for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is real-time reverse transcriptase-polymerase chain reaction (RT-PCR). It can be done on different samples: nasopharyngeal swabs (NPS) or oropharyngeal swabs (OPS), and self-collected saliva. However, negative findings do not rule out infection. Methods: A review was conceived to discuss advantages and limitations of the available diagnostic modalities for nonserologic diagnosis of SARS-CoV-2 based on RT-PCR; the article also proposes some practical suggestions to improve diagnostic reliability. Results: A total of 16 papers (corresponding to 452 patients) of the 56 initially identified were included. Most of the papers describe findings from different samples obtained in limited case series; comparative studies are missing. Conclusions: Diagnostic accuracy of NPS and OPS is suboptimal and the risk of contaminated aerosol dispersal is not negligible. The SARS-CoV-2 RNA can be found in self-collected saliva specimens of many infected patients within 7 to 10 days after symptom onset. There is an urgent need for comparative trials to define the diagnostic modality of choice. Adequate education and training of health care personnel is mandatory.
The sudden onset of the COVID-19 pandemic has put a strain on the whole scientific world.We assisted to a tremendous effort by researchers with the final goal of achieving a better management of COVID-19 patients. The world of otorhinolaryngology, likewise, has not been exempt from this commitment to research.In this commentary we perform a bibliometric review of the available academic literature about COVID-19 in the top 20-ranked ENT journal, with the goal of providing an overview of what has been published to date and encouraging a shift towards quantitative research.
Submandibular gland excision is generally performed through a transcervical approach, a safe procedure that, however, carries few neurological, functional and aesthetic drawbacks. Intraoral approach to the submandibular gland has been described many years ago but it has been newly proposed in recent years thanks to endoscope‐assisted and robot‐assisted surgical procedures. The main purpose of intraoral approaches is to avoid cosmetic sequelae and to reduce the risk of marginal nerve injury although the recent introduction of retroauricular, postauricular, facelift and transhairline neck incisions has overcome the need for an alternative to traditional transcervical approach. Different surgical approaches (transoral versus transcervical) to the submandibular gland as well as different type of cutaneous incisions will be illustrated and discussed in the light of advancement of endoscope‐assisted and robot‐assisted procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
