Otitis media - animation

An integral symptom of acute otitis media is ear pain; other possible symptoms include fever, and irritability (in infants). Since an acute otitis media is usually precipitated by an upper respiratory tract infection, there often are accompanying symptoms like cough and nasal discharge.

Otitis media

 

It occurs in the area between the tympanic membrane and the inner ear, including a duct known as the eustachian tube. It is one of the two most common causes of an earache - the other being otitis externa. Diseases other than ear infections can also cause ear pain, including cancers of any structure that shares nerve supply with the ear and shingles which can lead to herpes zoster oticus. Though painful, otitis media is not threatening and usually heals on its own within 2–6 weeks.

Tracheotomy - 3D Medical animation

Among the oldest described surgical procedures, tracheotomy (also referred to as pharyngotomy, laryngotomy, and tracheostomy) consists of making an incision on the anterior aspect of the neck and opening a direct airway through an incision in the trachea. The resulting stoma can serve independently as an airway or as a site for a tracheostomy tube to be inserted; this tube allows a person to breathe without the use of his or her nose or mouth. Both surgical and percutaneous techniques are widely used in current surgical practice.

Coblation Tonsillectomy

Coblation is a method used by otolaryngologists, also known as ENT (ear, nose and throat) specialists, to perform tonsillectomy, adenoidectomy, and other surgical procedures, including turbinate reduction and the treatment of snoring. Unlike traditional electrocautery methods, Coblation methods use radiofrequency ablation (RFA) to remove tissue. RF is a form of energy like radio waves, but with a higher frequency. Coblation-based surgical procedures use RF energy in a precise and controlled manner to remove affected tissue while causing very little harm to healthy tissue.The Coblation process was invented by Philip E. Eggers and Hira V. Thapliyal, who patented their “electrosurgical ablation probe” on May 11, 1999.The technology was acquired by ArthroCare (founded in 1993), a California-based medical device company, which trademarked the technology under the term Coblation—a contraction of “controlled” and “ablation”. Coblation tonsillectomy received U.S. Food and Drug Administration (FDA) clearance in 2001. The Coblation procedure is performed using specially designed hand pieces called Coblation wands. Coblation tonsillectomy involves either the complete (subcapsular) removal of the tonsil via dissection or the partial (intracapsular) removal of the tonsil in which the tonsil tissue is reduced by dissolving part of it away.
