The CO2 laser is a light artificially generated that works with high accuracy both in cutting and coagulation. Since all its rays are the same color and move towards the same direction, all the energy can be concentrated in one point, enabling it to work like a real "light scalpel".
Used with a surgical microscope it enables treating countless lesions, both benign and malignant, of the superior aero-digestive tracts (nose, mouth, pharynx, larynx) with the highest precision.
For information on the treatment of malignant lesions, visit the Head and neck cancer section.
Advantages of using laser
- Prevents or reduces hospital stay.
- Minimizes surgical damage.
- Minimizes operational bleeding.
- Prevents or lessens post surgical pain.
- Accelerates scar healing.
Laser Interventons in othorhinolaryngology
Benign nose and nasopharynx diseases:
- Nose and nasopharynx diseaseso Reduction of hypertrophic turbinates: an enlargement of the turbinates, which makes breathing difficult, comes with chronic rhinitis (both allergic and drug-induced). The diode laser enables an efficient reduction of the turbinates.
- Resection of septal spurs.
- Exeresis of benign tumours like polyps, cysts and papillomas.
- Resection of vascular lesions, such as angiofibromas and hemangiomas.
- Resection of nasal synechiae, which are adhesions between the septum and the external walls of the nose (turbinates) that appear often after surgery ortraumatisms.
- Choanal atresia opening: congenital malformation consistent lack of posterior nasal apertures. It can be unilateral or bilateral.
- Adenoid removal.
Benign mouth diseases:
- Resection of benign tumours: papillomas, fibromas, granulomas, cysts, ranula, hemangiomas.
- Resection of premalignant lesions: leukoplakias (white spot on the mucous membranes) and erythroplakia (reddened spots).
- Gum hyperplasia: swelling of the gums caused by multiplication of normal cells.
Benign oropharynx diseases:
- Chronic hypertrophic pharyngitis (also called chronic hyperplastic pharyngitis, granular pharyngitis, or follicular pharyngitis): the treatment consists in vaporizing the lymphatic tissue of the oropharynx. The mucus on the posterior pharynx wall is swollen, granular and reddened. There's abundant thick and colourless exudation. A sense of a strange body in the pharynx is almost always felt, which causes the patient to swallow and clear their throat. It can easily cause nausea and even vomits.
- Tonsil hypertrophy (enlarged tonsils): may cause apneas and it's treated with a partial laser tonsillectomy.
- Chronic and recurrent acute tonsillitis: The treatment consists in a total tonsillectomy. Using laser and microscope is more accurate, the bleeding is minimal and there's less post surgical pain.
- Lingual tonsil hypertrophy: there are tonsils that cover the posterior region of the tongue and may cause snoring and the feeling of a lump in the throat. It can be partially dried out by laser.
- Recurrent lingual tonsillitis: Infrequent cases of repeated infection of the lingual tonsils. If it could not be avoided with antibiotics, a laser lingual tonsillectomy can be performed.
- Vallecular cyst: The vallecula is a depression between the epiglottis and the base of the tongue.
Benign hypopharynx diseases: Cysts, papilomas and hemangiomas.
Benign larynx diseases:
- Congenital lesions
- Laryngomalacia: The most common congenital anomaly during infancy, in which the soft, immature cartilage of the upper larynx collapses inward during inhalation, causing airway obstruction and a high- pitched squeaking sound. This condition usually disappears when the child turns one, although severe cases can be solved by an endoscopic treatment with laser.
- Vocal cord paralysis.
- Laryngeal cysts.
- Subglottic hemangioma.
- Congenital subglottic strenosis.
- Acquired lesions
- Nodules, polyps, cysts, Reinke's edema.
- Post-intubation granuloma.
- Post-radiotherapy arytenoid edema.
- Laryngeal papillomatosis.
- Papilloma, hemangioma.
- Keratosis, leukoplakia, hyperplasia.
- Bilateral vocal cord paralysis: Posterior cordectomy.
- Larynx stenosis.
- Other stenosis caused by burns, acid or alkaline ingestion.
