Case Example

Emergent tracheotomy done 3 1/2 years ago due to inability to intubate at time of CABG (coronary artery bypass grafting). Tracheotomy tube was removed 3 months after it was placed due to poor tolerance "continuous coughing'. Despite successful use of CPAP, progressive shortness of breath warranted evaluation June 2011 with:

  • Spiromtery with peak inspiratory flow rate = 1.95 liters/second
  • Chest CT: narrowing involving the trachea at the level of the sternal notch extending over a length of 13 mm. The trachea measures 16 x 6 mm in maximum diameter at the narrowest part.

Note: Complicating factors of morbid obesity with underlying pulmonary abnormalities and sleep apnea warranted treatment with an open tracheotomy. In the absence of these comorbidities, other options could have possibly avoided a tracheotomy. Other options include tracheal resection or removal of anterior tracheal scar with interposition of tissue (strap muscles, sternocleidomastoid muscle). Endoscopic management was not felt to be a useful option due to the comorbidites above coupled with the soft lateral 'malacic' tracheal walls that readily accommodated a rigid dilator, but collapsed again on its removal.

Initial appearance of intact healing was followed by breakdown of the inferior flap dealt with by outpatient packing twice daily with iodoform gauze.

Appearance 1 1/2 years postop

     

The Dedo laryngoscope is placed into the posterior glottis with the tip separating the posterior membranous vocal cords (jet anesthesia)

Microdirect laryngoscopy with long 0 degree scope shows scarring anteriorly drawing lateral walls medially

Appropriate site of entry into trachea for tracheotomy determined with 25 gauge needle placed percutaneously through previous tracheotomy site

Four-flap epithelial lined tracheotomy outlined (with anterior cervical lipectomy and thyroid isthmusectomy)

Two gelpy retractors used to identify large multinodular goiter after anterior cervical lipectomy accomplished along with midline separation of strap muscles

A large portion of the midline thyroid is removed and sent for pathologic assessment (permanent section)

   
   

Postoperative Day #5 at time of tracheotomy change from #6 cuffed Shiley to #6 metal Jackson

With #6 metal cuffless Jackson tracheotomy good phonation achieved to be improved with use of Passey-Muir valve.
