Are you fed up with sneezing, nasal blockage, wheezing, itchy eyes nose and throat, dry cough, used all kinds antihistamines, nasal sprays, injections and still suffering, then only need to read this post-
Allergic rhinitis, often called nasal allergy occurs when your immune system overreacts to particles in the air that you breathe. The immune system attacks the particles in your body, causing symptoms such as sneezing and a runny nose. The particles are called allergens, which simply mean they can cause an allergic reaction.
In most cases, when you have allergic rhinitis:
and Sneezing especially after you wake up in the morning.
and Runny nose and postnasal drip. The drainage from a runny nose caused by allergies is usually clear and thin. But it may become thicker and cloudy or yellowish if you get a nasal or sinus infection.
and Eyes are watery and itchy.
and Throat may feel itching
and Dry cough
and At times wheezing-Asthma
and Eczema-Allergic rashes in skin
When to undergo Laser Surgery
If you are fed up using all kinds of nasal sprays, antiallergic medications and injections, and no avail, then think of this minor surgery â€“Laser Surgery under local anesthetic. It gives very good result. And not very expensive, when done as a day case procedure.
The Laser cautery is performed under local anesthetic, spraying lidocaine and xylometazoline. If any septal spur to be removed, inject 4% Xylocaine with adrenaline.
Patient is kept semi sitting in an ENT chair (as seen in picture) and Co2 CW at 6 watts setting, the turbinates are cauterized. The procedure takes 10-15 mnts on each side. There is hardly any bleeding and patient goes home after few hours. This gives very good results
Post operative care-
Nasal decongestants, analgesics and antihistamines are given for a week or two. Nasal wash with saline helps healing. There is no crusting.
How Laser work?
The pathogenesis is actually type I hypersensitive reaction of nasal mucosa. Agger nase is one of the trigger points and sensitive areas of this disease, and anterior ethmoidal nerve is the major nose-innervating parasympathetic nerve, the abnormal excitation of which plays an important role in the pathogenesis. Anterior ethmoidal nerve is distributed at the supra-anterior portion of nasal cavity, where gland density is high. Irradiation of anterior ethmoidal nerve, lateral branch and septal branch in this area will not only damage inflow of parasympathetic nerve, but also decrease acetylcholine released from nasal cavity, thereby alleviating symptoms. Meanwhile, anterior ethmoidal nerve is also a sensory nerve of supra-anterior portion of nasal cavity; the sensory function will be weakened after laser cauterization.
Laser cautery will decrease sensitivity of external nose to adverse chemical or physical stimuli. The effect of CO2 laser irradiation is as follows:
and The excitability of anterior ethmoidal nerve is decreased, and thereby vascular permeability and nasal secretion are also decreased.
and Some of sensory nerves have been cut, the sensory-parasympathetic nerve reflex is weakened, and at the meantime release of vascular-origin intestinal peptide as well as substance P is also decreased.
and Scar formation of nasal mucosa will prevent hypersensitivity.
Advantages of Co2 Laser
CO2 laser has got good flexibility, high focus of energy and minimal injury to the surrounding normal tissue. It will cause coagulation, degeneration and atrophy of protein, and cause damage of varied degree to certain branch of anterior ethmoidal nerve and sphenopalatal nerve. Moreover, laser therapy will destroy glands in this area, decreasing secretion and sensitivity of nasal mucosa to adverse external stimuli, suppressing reflex of sneezing. Thus nasal discharge and obstruction will be lessened and symptoms alleviated.
CO2 laser has such advantages as precise targeting, easy manipulation, causes no bleeding, fewer complications, good response and quick recovery. During the treatment, power output and coagulation time are to be strictly controlled, and surrounding normal tissue is to be well protected in order to ensure both efficacy and safety of treatment.
