    Pharyngoscopy is an integral part of the overall initial survey conducted by the otolaryngologist (ENT doctor «ear, nose and throat»). This examination is performed in the following order: inspection of the external nose and anterior rhinoscopy, pharyngoscopy, indirect laryngoscopy, examination of the ear, otoscopy. Laringoscopice examination is also an integral part of the initial examination at the dentist.

    • nasal tweezers;
    • nasopharyngeal and laryngeal mirror;
    • probes – pharyngeal and mindalikovye;
    • wetterhall.
