OBJECTIVETo study effect of shoulder joint function after rotator cuff repair of polylactic acid absorbable membrane.

METHODSFrom September 2015 to December 2016, 50 patients diagnosed with rotator cuff tear were selected and divided into treatment group and control group. There were 25 patients in control group, including 12 males and 13 females, with an average age of (48.7±3.5) years old, who received simple arthroscopic rotator cuff repair. There were 25 patients in treatment group, including 11 males and 14 females, with an average age of(49.2±4.1) years old, who performed arthroscopic rotator cuff repair with implanting polylactic acid absorbable membraneon shoulder of rotator cuff. Preoperative and postoperative VAS score, ASES score and UCLA score were recorded and compared between two groups.

RESULTSAt 6 months after operation, preoperative VAS score in control group was 5.48±1.12, and decreased as 1.28±0.84 after operation; ASES score before operation was 52.24±4.64, and improved to 86.92±3.20 after operation;preoperative UCLA score improved from 14.36±1.89 before operation to 30.72±1.28 after operation. In treatment group, VAS score decreased from 5.36±1.32 before operation to 1.40±0.71 after operation;preoperative ASES score was 51.04±4.09, and improved to 88.96±2.79 after operation; UCLA score improved from 15.12±1.81 before operation to 32.12±1.33 after operation. There was no significant difference in VAS score between two groups, and ASES score, UCLA score in treatment group was obviously better than control group.

CONCLUSIONSApplication of polylactic acid absorbable medical membrane could obviously improve shoulder function, and effectively prevent acromion adhesion after arthroscopic rotator cuff repair.

PURPOSE: Percutaneous epidural neuroplasty (PEN) is a minimally invasive treatment. The efficacy of PEN has been relatively well investigated; however, the relationship between the clinical effectiveness of PEN and the severity of spinal canal stenosis by disc material has not yet been established. The purpose of this study was to compare clinical outcomes of PEN according to the dural sac cross-sectional area in single level disc disease. MATERIALS AND METHODS: This study included 363 patients with back pain from single level disc disease with and without radiculopathy. Patients were categorized into groups according to spinal canal compromise by disc material: Category 1, less or more than 50%; and Category 2, three subgroups with lesser than a third, between a third and two thirds, and more than two thirds. Clinical outcomes were assessed according to the Visual Analog Scale (VAS) score for back pain and leg pain and Odom's criteria at 1, 3, 6, 12, and 24 months after treatment. RESULTS: The demographic data showed no difference between groups according to spinal canal compromise by disc material except age (older age correlated with more spinal canal compromise). The dural sac cross-sectional area did not correlate with the VAS scores for back and leg pain after PEN in single level disc disease in Groups 1 and 2. Odom's criteria after PEN were also not different according to dural sac cross-sectional area by disc material. CONCLUSION: PEN is an effective procedure in treating single level lumbar disc herniation without affecting dural sac cross-sectional area.

Postoperative epidural adhesion is one of the most common causes of failed back surgery syndrome (FBSS), which can lead to back and leg pain or neurological deficit. Prevention of epidural adhesion after laminectomy is critical for improving the outcomes of lumbar surgery. The main origins of epidural fibrosis are raw surface of erector muscles and rupture fibers of intervertebral disc. The main current preventive methods for epidural adhesion include the usage of implants, chemicals and low dose radiation. However, most of them are still in experiment period. There are still controversies on the clinic usage of autograft free fat, ADCON-L, and Mitomycin C (MMC). The optimal implants are characteristics of better biocompatibility, degradable absorption and capability of existing for a certain period in body. The optimal medicine should have good effect on anti-desmoplasia, less side effects and long half-life. Besides, the combination of biodegradable medical film and drug and the mixture of two or more medical films are also the research frontlines of epidural adhesion. Further researches are required to explore new materials and drugs with stable and most favorable effect in preventing epidural adhesion.

PURPOSE: To compare corneal flaps created in rabbits with a 60 kHz femtosecond (FS) laser using different levels of raster energy and to measure early inflammation, corneal stromal cell death, and late postoperative adhesion strength. METHODS: Sixty rabbits were divided into three groups of 20 each. A flap 110 micrometer thick and 9.0 mm in diameter was made in one eye of each rabbit at raster energies of 0.7 microJ, 1.1 microJ, and 2.4 microJ. Histopathological evaluation for inflammation and apoptosis using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was performed at 4 and 24 hours after flap creation. The adhesion strength of the flaps was measured with a tension meter at 1 and 3 months. RESULTS: Twenty four hours after flap creation, the 2.4 microJ group had more inflammatory and CD11b-positive cells than the 0.7 and 1.1 microJ groups. The number of TUNEL-positive cells increased with raster energy at 4 and 24 hours. The grams of force (gf) needed to detach the flaps at 3 months was significantly higher in 2.4 microJ group (170 gf) than in 0.7 microJ group (97.5 gf) and 1.1 microJ group (100 gf, p = 0.03). CONCLUSIONS: Using raster energy lower than 1.1 microJ to make a flap with a 60 kHz FS laser decreases inflammatory cell infiltration and corneal stromal cell death in the central cornea but may result in a weaker flap than using higher raster energy (2.4 microJ).

OBJECTIVETo evaluate the efficacy of cartilage tympanoplasty in the treatment of adhesive otitis media.

METHODSFrom June to October, 2008, 18 patients with adhesive otitis media (18 ears) were treated with tragus cartilage tympanoplasty. The air-bone gap changes and the self-perceived symptomatic improvement were evaluated at 1 month and 1 year after the operation.

RESULTSAll the patients showed dry ear within 6 weeks after the operation. Tympanic membrane healing was achieved in 17 cases, and 1 case presented with a inferior-anterior fissure in the tympanic membrane. With the average preoperative air-bone gap (at 0.25, 0.5, 1.0, and 2.0 kHz) of 44.65 dB, the patients showed an obvious decrease of the air-bone gap by over 10 dB at 1 month after the operation and by over 25 dB at one year. Symptomatic improvements were achieved in these cases, including alleviated ear discomforts (3/15 cases), total tinnitus relief (1/11 cases), and alleviated tinnitus (10/11 cases). High-frequency tinnitus was noted in 1 case (1/7 cases), and the tympanic membrane appeared normal in 17 cases.

CONCLUSIONTympanic membrane reconstruction using the tragus cartilage can be feasible for treatment of secretory otitis media, but the surgical indications should be carefully controlled.

OBJECTIVE: To investigate the reason for the adhesion of vocal cord after CO2 Laser laryngeal surgery. METHOD: One hundred and nineteen patients who were untaken CO2 Laser laryngeal microsurgery. RESULT: Among 119 cases, 9 cases of bilateral vocal cord paralysis, 42 cases of vocal cord polyps and 3 cases of precancerous laryngeal lesions did not show vocal cord adhesion after CO2 Laser laryngeal microsurgery. Contrarily, one of 5 cases with laryngeal stenosis, 5 of 41 cases with laryngeal papilloma and 6 of 19 cases with laryngeal carcinoma shew the adhesion of vocal cord after CO2 Laser laryngeal microsurgery. CONCLUSION Through selecting the appropriate patient and surgery spot, processing correctly during and after surgery, using the suitable dosage of laser and reducing the heat radiation, the adhesion of vocal cord can be avoided after CO2 Laser laryngeal surgery.

PURPOSE: To evaluate the usefulness of OCT retinal mapping in determining the configuration of a vitreomacular adhesion and selecting a meridian for entry into the subhyaloid space in patients with vitreomacular traction syndrome. METHODS: Six consecutive patients (6 eyes) with vitreomacular traction syndrome underwent vitrectomy with peeling of posterior hyaloid. Ocular coherence tomography (OCT) retinal mapping was performed preoperatively. Access to the subhyaloid space was made by creating an opening with a 25 gauge needle at a location where the detached posterior hyaloid membrane was farthest from the retinal surface. The location was selected based on six preoperative meridional OCT scans. The posterior hyaloid was then gently peeled off in a circular fashion around the fovea with a micropick. Visual acuity and foveal thicknesses were measured before the operation and 3 months afterwards. RESULTS: After the operation, visual acuity improved and central macular thicknesses were reduced significantly in all six patients. The best corrected visual acuity improved from 0.4 to 0.75 with a mean increase by 3.5 lines on a Snellen chart 3 months after the operation. The mean foveal thickness was reduced from 406 micrometer to 241 micrometer. The restoration of foveal pit was observed in five patients. Neither intraoperative nor postoperative complications were observed during the follow up period. CONCLUSIONS: An OCT retinal mapping program is a valuable diagnostic tool in understanding the configuration of vitreomacular adhesion and planning the surgical approach for operating on vitreomacular traction syndrome.

PURPOSE: Postoperative intraabdominal adhesion formation is a major clinical problem. No previous study was found, reporting the relationship between adhesion formation and melatonin administration, but melatonin, a strong antioxidant, is recognized to have certain effects on the progression of adhesion formation mechanism. It was therefore decided to investigate the effects of melatonin on postoperative adhesion formation. MATERIALS AMD METHODS: A total number of 24 Spraque-Dawley rats were utilized. Three groups, described as: Group A, sham laparatomy (n=8), Group B, rats that underwent only ischemia-reperfusion (n=8) and Group C, rats that underwent ischemia- reperfusion and were given 10 mg/kg melatonin solution i.v. (n=8). For Groups B and C, the ileocolic vessels were clamped. Blood glutathione peroxidase levels of all study groups were assessed, then microscopic and macroscopic adhesion scores were evaluated. RESULTS: Glutathione peroxidase levels of the melatonin-treated group were significantly higher and fibroblast proliferation and macroscopic adhesion scores were significantly lower, than in the melatonin-free group. CONCLUSION: The results of this study supported the hypothesis, that melatonin administration may prevent intraabdominal adhesions resulting from surgery.
