Cordectomy
Cordectomy is the surgical removal of a cord. It usually refers to removal of the vocal cord, often for the purpose of treating Laryngeal Cancer . The word is derived from the Greek, combining "Chorde" and "ektome" meaning excision. It can be carried out by traditional surgical techniques or, increasingly, by Carbon Dioxide Laser . CO2 laser cordectomy has allowed the treatment of glottic carcinoma as a day case procedure . The procedure has also been carried out by vets to prevent incessant barking by dogs . In Human, this type of surgeries are usually done by the Otolaryngologists and Oral & Maxillofacial Surgeons.
Prior to surgery, the patient must be informed of serious, debilitating, and permanent consequences of surgery, most notably the loss of speaking capacity with severity correlating to the portion of vocal cords removed. A patient will be incapable of producing most vocal sounds following total cordectomy, although certain primal deep guttural screams may still be produced, with the patient almost always retaining the ability to speak in whispers. There is little no chance of a patient recovering their voice following a complete or near-complete cordectomy as the procedure literally removes the organs responsible for vocal utterances, and patients with a less-than-entire cordectomy will always lose some or most of their vocal range (again corresponding to the section and amount of removed vocal cords). Doctors are encouraged to explore alternative communication technologies with patients (such as voice-boxes, whisper-amplifying devices, and text=to-speak software) prior to determining the acceptability of the procedure. Patients should be made to understand that the procedure is absolutely permanent and their vocal capacity (with current technology) will never recover to its range prior to the surgery, and patients with small percentages of cord removals will experience disproportionately severe loss of vocal range compared to the loss suffered by patients who have undergone a near-entire cordectomy procedure.
The indications being Carcinoma of Vocal cords and Early Glottic Carcinoma etc.
According to the European Laryngeal Society, Cordectomy is classified into followings:
1)Type I : Subepithelial cordectomy 2)Type II : Subligamental cordectomy 3)Type III: Transmuscular cordectomy 4)Type IV : Total or Complete cordectomy
