Study Notes

  • Morrison's mastoid attractor, also known as Morrison's self-retaining hemostatic mastoid retractor, is used in medical procedures for retracting soft tissues after incision and flap elevation, commonly used in harvesting temporalis fascia, mastoidectomy, tympanoplasty, and head and neck surgeries.
  • St.Clair Thompson's nasal speculum is a long-bladed instrument with concave insides used for interior rhinoscopy and diagnosing lateral wall of the nose and nasal cavity. It is also used therapeutically for removal of foreign bodies, nasal packing, and submucous resolution of the nasal septum.
  • Delay dressing forceps, similar to Tillis dressing forceps, have a box joint or spheroid and serrated, grooved jaws and are used for packing or unpacking ear canals or mastoid cavities, delivering medicated dressing into ear canals, and removing foreign bodies or crusts from the nose or ear.
  • Herman dressing forceps, similar to Tillis dressing forceps, have a spheroid and are used for the removal of foreign bodies from the nose.
  • Tongue depressors come with a flat end for depressing the anterior 2/3 of the tongue to prevent gag reflex during examination of the oral cavity and various tests. They are also used for taking septic squeeze tests to test gag reflex, cold spatula tests to check patency of nasal passages, and oral cavity procedures like injection of steroids, biopsy, and excision of cysts.
  • Boyle-Davies mouth gag is used for opening the mouth and depressing the tongue during various oral surgeries like palate surgery, soft palate surgery, tonsillectomy, and fat pad injections. It comes with two components, the Boile blade and Davis blade, and is maintained in position using dressings bipods.
  • Jennings mouth gag is used for keeping the mouth open during intraocular surgeries when retraction of the tongue is not required or desirable. It is generally applied in the center of the mouth and can be used in dental surgeries.
  • Dressing bipods consist of two rods with multiple rings used to anchor and fix the boils Davis mouth gag.
  • Tonsil holding forceps, also known as Dalys forceps, are used to hold the tonsil during tonsillectomy surgeries.
  • Tonsil artery forceps, available in both straight and curved types, are used for ligation of the bleeding point during tonsillectomy procedures.
