Method for eliminating lacrimal canaliculus

FIELD: medicine.

SUBSTANCE: method involves probing and rinsing lacrimal canaliculus. Working nozzle of YAG laser is additionally introduced into lacrimal canaliculus to reach medial wall of the lacrimal sac. The working nozzle of laser is taken away from the medial lacrimal sac wall in the reverse direction by 2 mm. Laser radiation treatment is applied in constant wave mode (CW) with power of 2.5 W during 5 s in smoothly moving laser working end from the lacrimal canaliculus. The lacrimal canaliculus is washed with corticosteroids.

EFFECT: enhanced effectiveness of treatment.

 

The invention relates to medicine, namely to ophthalmology, and can be used to create the lacrimal fluid outflow when limited obliteration of lacrimal canaliculi.

Currently, the problem of surgical treatment of diseases of the lacrimal passages are still far from the final solution and requires further study and improvement.

A known method of surgical treatment of limited obliteration of lacrimal canaliculi (like m.l.krasnov, Vasev. The guide eye surgery. -Moscow: Medicine, 1988. -P.472). The method consists in the following. In the lacrimal canaliculus injected conical probe, which break adhesions, and spend it in the lacrimal SAC to the inner wall and leave there. After that make the skin incision with a length of 1.5-2.0 cm 3-5 mm above the inner eyelid adhesions at a distance of 3-4 mm from it to the side of the nose, below the cut is bent outwards. Usepreview the soft tissue at the side of the nose, find inner spike century, which is cut, if the lacrimal SAC is small. Then check the movement of the probe, whether it is in the lacrimal SAC, then through the lacrimal canaliculus spend shortened to 2/3 normal sewing needle with a tuft of horsehair. The wall of the lacrimal SAC puncture needle, hair bun output and connect their ends, sew up the wound. The wound edges smeared solution of brilliant green is my, for ever put antibacterial ointment and dressings. Bunch of hair, leave for 2-3 weeks. To prevent Sardinia lacrimal canaliculi a tuft of hair prodelyvat daily and the other side.

The disadvantage of the above method are the skin incision, holding horsehair with its subsequent prodelyvaniem.

The closest in technical essence is a remedy obliteration of lacrimal canaliculi by mechanical expansion of the lacrimal canaliculi (Grammatikovskiy, Try. A practical guide to treatment of diseases of the lacrimal organs. -Minsk: Belarusian scienceā€, 2000. -S). The method consists in the following. After epibulbar anesthesia 0,25-0,5% solution dikaina and infiltration with 2% solution of novocaine (1.0 to 1.5 ml) in the area of tubule last extend initially conical, and then the cylindrical probes to # 3. Control lavage ensure patency of the lacrimal passages. In a few days in the conjunctival SAC buried disinfectant drops.

This method of treatment provides a high (60-70%) therapeutic effect, however, this method has limitations and drawbacks: when you break the adhesions probe bleeding occurs, increasing the duration of operation and in the postoperative period is the development of a secondary infection, re-poured the radio lacrimal canaliculi.

The technical result of the invention is to significantly improve functional and cosmetic effect, reducing the morbidity of the operation.

This technical result is achieved by the method of elimination obliteration of lacrimal canaliculi, which consists in probing of lacrimal canaliculi first cone, then cylindrical probes to No. 3, the irrigation of the lacrimal canaliculi, the impact YAG laser radiation on the walls of the lacrimal canaliculi in the continuous wave (CW) output power of 2.5 watts for 5 seconds and repeated washing of the lacrimal canaliculi corticosteroid.

The specified mode is set experimentally. Work the tip of the laser is in the diameter of 0.56 mm, after sensing passes freely inside the lacrimal canaliculi, and coagulating (including antibacterial and hemostatic) the laser be on the areas of direct contact with the wall of the lacrimal canaliculi. Washing corticosteroids reduced the inflammatory process that occurs when exposed to a laser. At lower power or duration of radiation is not provided functional outcome in the long term (>1 year) observations (obliteration occurs in 60% of cases - as in the absence of laser irradiation). With increasing power or deletelines and radiation begin to show signs of tissue necrosis, in the long term obliteration occurs in 70% of cases.

The proposed method reduces the likelihood of bleeding, surgery duration, observed high accuracy and melodramatically operations. In the postoperative period is not observed complication secondary infection, long-term (over 1 year) is high (85%) functional effect.

The method is as follows.

After epibulbar anesthesia with 0.25%and 0.5% solution dikaina and infiltration with 2% solution of novocaine (1.0 to 1.5 ml) in the area of tubule last extend the first cone, and then the cylindrical probes to # 3. Control lavage ensure patency of the lacrimal canaliculi. Then in the lacrimal canaliculus enter the working tip of a YAG laser to the medial wall of the lacrimal SAC. After discharge of the working tip YAG laser from the medial wall of the lacrimal SAC in the opposite direction by 2 mm include laser installation and energy in continuous wave (CW) output power of 2.5 watts for 5 seconds smoothly (without jerking) deduce the working tip of the laser from the lacrimal canaliculi. Lacrimal canaliculus washed with corticosteroids when the operation completes and the next 3 days. Also over the next 7 days after surgery in the conjunctival SAC buried disinfectant drops.

Example 1. B is supplemented flax B. 37 years old, he enrolled in the eye Department with complaints of moderate tearing of the right eye, caused by obliteration of the lower lacrimal canaliculus. Objective examination of the patient notice: the stagnation of the tear stream, lachrymation of the right eye, the patient is forced to wipe the tears away every 25-30 minutes. The lacrimal punctum and the position of the eyelids of the right eye almost without pathological changes. When washing lacrimal passages installed the lack of permeability through the lower lacrimal point while maintaining a good road through the upper lacrimal point. On radiographs lacrimal passages with contrast agent installed obliteration of the lower lacrimal canaliculus in the medial part. When rinoskopii disorders of the nasal mucosa is not revealed: the nasal passages wide, pathological secretions in the nose no, breathe freely.

In connection with the identified obliteration of the lower lacrimal canaliculus is performed by the proposed method.

After epibulbar anesthesia 0,25-0,5% solution dikaina and infiltration with 2% solution of novocaine (1.0 to 1.5 ml) in the area of tubule last expanded first cone, and then the cylindrical probes to # 3. Control washing 1 ml of 0.1% hydrocortisone was convinced of the patency of the lacrimal canaliculi. Then tear the canadian entered the work Nakonechny the YAG laser to the medial wall of the lacrimal SAC. After discharge of the working tip YAG laser from the medial wall of the lacrimal SAC in the opposite direction by 2 mm included laser installation and energy in continuous wave (CW) output power of 2.5 watts for 5 seconds smoothly (without jerking) drew the working tip of the laser from the lacrimal canaliculi. Lacrimal canaliculus were washed in 1 ml of 0.1% solution of hydrocortisone in the conjunctival SAC buried 0.25% solution of chloramphenicol. After surgery in the next 3 days lacrimal canaliculus were washed in 1 ml of 0.1% solution of hydrocortisone and within 7 days in the conjunctival SAC of the right eye was buried 0.25% solution of chloramphenicol.

Operating and postoperative complications were not observed. The tears stopped. Patency of lacrimal passages recovered. Surveillance for 2 years showed the stability of the results.

Clinical observations were captured in 14 patients. Preoperative examination included: history, biomicroscopy, examination provisions of the lacrimal points and patency of lacrimal passages, endoscopic examination of the nasal cavity.

Physical examination before surgery in all patients the position of the correct age, the lacrimal punctum correct form. When pressed on the internal ligament eyes remained stagnant tear stream. When scanning active terrain with the help of the colored samples (tubular and nasal) revealed reduced patency of lacrimal passages in the obliteration of one of the tear tubules and absence of permeability with obliteration of both lacrimal tubules. On radiographs lacrimal passages with contrast substance was confirmed obliteration of lacrimal tubules. When endoscopic examination of the nasal cavity revealed that the anatomical changes that prevent operation no.

In the postoperative period was monitored condition kazootoys apparatus in different periods of time (daily for the first week after surgery, then after 1, 3, 9, 15, and 20 months). The results showed that kazootoys road passable in 12 (85,7%) patients.

Thus, the proposed method provides high functional recovery results of lachrymal, reduces the likelihood of bleeding, duration of operation, eliminates secondary infection, observed high accuracy and melodramatically operations.

Solution obliteration of lacrimal canaliculi, which consists in probing and irrigation of the lacrimal canaliculi, characterized in that it further in the lacrimal canaliculus enter the working tip of a YAG laser to the medial wall of the lacrimal SAC, assign work the tip of the laser from the medial wall of the lacrimal SAC in the opposite direction by 2 mm, the effect of laser radiation with a continuous wave (CW) power 2.5 W for 5 s, smoothly bringing the working tip of the laser from the lacrimal Kahn is Liza, lacrimal canaliculus washed with corticosteroids.
