The laringectomie are a group of different interventions subtotals facing l ’ objective to remove cancers of the larynx allowing, recovery completed, to breathe, talk and eat naturally.
The main function of the larynx is to correctly route the saliva and food to nurture and l ’ air towards the trachea prevent liquids and food go accidentally into the Airways (inhalation).
Paradoxically, the voice is an ancillary function of the larynx (many animals have the larynx but not speak) You can't recover even after complete removal of the larynx (see talk after total laryngectomy).
The surgeon with these interventions diametrically l ’ Anatomy and physiology of the larynx, After the intervention the ’ neolaringe make completely different movements than the normal situation but fails to effectively protect the airway from food, allows a normal ’ air passage and is capable of producing a good voice.
There are many variants of this surgery techniques that are called with the name of the surgeon who l ’ has created or disseminated in history (Subtotal laryngectomy second Labayle, Mayer-Piquet, Juice-Rahi) a more recent classification defines three types of HOLS (Horizontal System Laryngectomy).
This surgery is United by the preservation of at least one ’ cricoaritenoidea unit that is one half of the bezel of the cricoid cartilage and arytenoid correspondent.
Laryngectomy according to Mayer-Piquet (HOLS type IIa): removed all thyroid shield, you remove both vocal cords and remove the sottoioidea portion of ’ Epiglottis (You can also remove an arytenoid ’), then you make a suture (Pandian) combining all ’ all ’ hyoid cricoid and Epiglottis sovraioidea (cricoioidoepiglotopessia).
Laryngectomy second Labayle (HOLS type IIb): removed all thyroid shield, you remove both vocal cords and remove all the ’ Epiglottis (You can also remove an arytenoid ’), then you make a suture (Pandian) combining all cricoid ’ hyoid bone (cricoioideoepiglottopessia).
Laryngectomy second juice-Rahi (HOLS type IIIa – IIIB): removed all thyroid shield, you remove both vocal cords, cricoid ring is removed and removes all ’ l or in part l ’ Epiglottis (You can also remove an arytenoid ’), then you make a suture (Pandian) combining the trachea all ’ hyoid bone (tracheoioideoepiglottopessia/tracheoepiglottopessia).
This type of intervention is indicated for large tumors also provided do not involve some critical areas, the specialist expert is able to properly l ’ indication in this type of surgery
