Lateral Ridge Augmentation

Autogenous dentin has been reported to be a suitable grafting material for certain indications. The purpose of this study was to assess the feasibility of using endodontically treated teeth for this application. In the present retrospective study, one-stage augmentation of lateral ridge defects with a dentin shell and particulate (tooth shell technique (TST)) either obtained from endodontically treated teeth (ETT, 17 patients with 21 implants) or non-endodontically treated teeth (NETT, 17 patients with 24 implants) were analyzed. Follow-up was conducted 3 months after augmentation. The target parameters were biological complications, horizontal hard tissue loss, osseointegration, and the integrity of the buccal lamella. Only minor complications occurred in three implants from three patients, including two cases of wound dehiscence (one each in ETT and NETT) and a localized three-walled defect in the NETT group, which was solved by re-augmentation. All the implants were osseointegrated and the integrity of the buccal lamella was preserved. The mean difference of the resorption of the crestal width and the buccal lamella did not differ statistically between the two groups. As TST using ETT showed, the results comparable to those of NETT dentin from endodontically treated teeth can be safely applied with predictable results for this grafting technique.

Lateral Ridge Augmentation

In the literature, autogenous dentin is considered a possible alternative to bone substitute materials and autologous bone for certain indications. The aim of this proof-of-concept study was to use autogenous dentin for lateral ridge augmentation. In the present retrospective study, autogenous dentin slices were obtained from teeth and used for the reconstruction of lateral ridge defects (tooth-shell technique (TST): 28 patients (15 females, 13 males) with 34 regions and 38 implants). The bone-shell technique (BST) according to Khoury (31 patients (16 females, 15 males) with 32 regions and 41 implants) on autogenous bone served as the control. Implants were placed simultaneously in both cases. Follow-up was made 3 months after implantation. Target parameters during this period were clinical complications, horizontal hard tissue loss, osseointegration, and integrity of the buccal lamella. The prosthetic restoration with a fixed denture was carried out after 5 months. The total observation period was 5 months. A total of seven complications occurred. Of these, three implants were affected by wound dehiscences (TST: 1, BST: 2) and four by inflammations (TST: 0, BST: 4). There were no significant differences between the two groups in terms of the total number of complications. One implant with TST exhibited a horizontal hard tissue loss of 1 mm and one with BST of 0.5 mm. Other implants were not affected by hard tissue loss. There were no significant differences between the two groups. Integrity of the buccal lamella was preserved in all implants. All implants were completely osseointegrated in TST and BST. All implants could be prosthetically restored with a fixed denture 5 months after augmentation. TST showed results comparable to those of the BST. Dentin can therefore serve as an alternative material to avoid bone harvesting procedures and thus reduce postoperative discomfort of patients.

Abstract Introduction Laparoscopic fundoplication (LF) has almost completely replaced the open procedure performed for gastroesophageal reflux disease (GERD) and hiatus hernia (HH). Several studies have suggested that long-term results with surgery for GERD are better than a medical line of management. In this retrospective study, we outline our experience with LF over 10 years. Also, we analyze the factors that would help us in better patient selection, thereby positively affecting the outcomes of surgery. Patients and Methods In this retrospective study, we identified 27 patients (14 females and 13 males) operated upon by a single surgeon from 2010 to 2020 at our institution. Out of these, 25 patients (12 females and 13 males) had GERD with type I HH and 2 (both females) had type II HH without GERD. The age range was 24 to 75 years. All patients had undergone oesophago-gastro-duodenoscopy (OGD scopy). A total of 25 patients had various degrees of esophagitis. Two patients had no esophagitis. These patients were analyzed for age, sex, symptoms, preoperative evaluation, exact procedure performed (Nissen’s vs. Toupet’s vs. cruroplasty + gastropexy), morbidity/mortality, and functional outcomes. They were also reviewed to examine the length of stay, length of procedure, complications, and recurrent symptoms on follow-up. Symptoms were assessed objectively with a score for six classical GERD symptoms preoperatively and on follow-up at 1-, 4- and 6-weeks postsurgery. Further evaluation was performed after 6 months and then annually for 2 years. Results 14 females (53%) and 13 males (48%) with a diagnosis of GERD (with type I HH) and type II HH were operated upon. The mean age was 46 years (24–75 years) and the mean body mass index (BMI) was 27 (18–32). The range of duration of the preoperative symptoms was 6 months to 2 years. The average operating time dropped from 130 minutes for the first 12 cases to 90 minutes for the last 15 cases. The mean hospital stay was 3 days (range: 2–4 days). In the immediate postoperative period, 72% (n = 18) of the patients reported improvement in the GERD symptoms, while 2 (8%) patients described heartburn (grade I, mild, daily) and 1 (4%) patient described bloating (grade I, daily). A total of 5 patients (20%) reported mild dysphagia to solids in the first 2 postoperative weeks. These symptoms settled down after 2 to 5 weeks of postoperative proton-pump inhibitor (PPI) therapy and by adjusting consistency of oral feeds. There was no conversion to open, and we observed no perioperative mortality. There were no patients who underwent redo surgeries in the series. Conclusion LF is a safe and highly effective procedure for a patient with symptoms of GERD, and it gives long-term relief from the symptoms. Stringent selection criteria are necessary to optimize the results of surgery. Experience is associated with a significant reduction of operating time.

Objective: To compare the two surgical procedures Snod gross & parameatal based flap technique for mid & distal penile hypospadias including cosmosis. Study design: Randomized Clinical interventional trail. Place of study: This study was conducted in the Urology Department of Assir Central University Hospital ABHA, KSA and Department of Urology & Renal transplantation, Jinnah Hospital, Lahore from June 2002 to Dec 2004. Material & Methods: Thirty-two patients were selected for this randomized clinical intervention study with mid shaft & distal hypospadias fulfilling the inclusion criteria. Snod Gross and parameatal based flap technique was assigned randomly to patients comprising of two groups of sixteen each. Watertight closure was made with 6/0 vicryl. Tourniquet or 1:10000 epinephrine were used. Follow up at 2 weeks, three months; 6 months post catheter or stent removal and the patient were assessed on criteria of cosmosis, time for surgery and complications associated with the procedure. Results: Th irty-two patients who underwent procedure of Snodgross & parameatal-based flap in the management of mid shaft & distal penile Hypospadias. Age ranged from 2-12 years. The mean age was 5.23+4 years. The presentation of patients was dystocia of external meatus with misdirected stream in sixteen (50%) patients, spraying of urine in six (25%) and narrow stream in 4(13%) patients. Eighteen patients were having distal penile and fourteen were having mid shaft hypospadias. Following Snod grass technique all patients had good cosmetic results without any complication. Following parameatal based flap, one patients (6.3%) develop wound dehiscence, three patients (18.8%) develop urethral fistula, two patients (12.5%) showed metal retrieval and twenty patients showed good cosmosis. In our study, comparison between Snodgross & parameatal-based flap, the success rate was 100% and 62.4% respectively. Conclusions: Success with Snod gross procedure is better with no complications and good cosmosis. Complications rate was 37.6 % in-patient with para-meatal technique.

Abstract AimTo investigate the effect of orthokeratology (OK) lens on axial length (AL) elongation in myopia with anisometropia children.MethodsThirty-seven unilateral myopia (group 1) and fifty-nine bilateral myopia with anisometropia children were involved in this 1-year retrospective study. And bilateral myopia with anisometropia children were divided into group 2A (diopter of the lower SER eye under − 2.00D) and group 2B(diopter of the lower SER eye is equal or greater than − 2.00D). The change in AL were observed.The datas were analysed using SPSS 21.0.Results(1) In group 1, the mean baseline AL of the H eyes and L eye were 24.70 ± 0.89 mm and 23.55 ± 0.69 mm, respectively. In group 2A, the mean baseline AL of the H eyes and L eyes were 24.61 ± 0.84 mm and 24.00 ± 0.70 mm respectively. In group 2B, the mean baseline AL of the H eyes and L eyes were 25.28 ± 0.72 mm and 24.70 ± 0.74 mm. After 1 year, the change in AL of the L eyes was faster than the H eyes in group 1 and group 2A (all P<0.001).While the AL of the H eyes and L eyes had the same increased rate in group 2B. (2) The effect of controlling AL elongation of H eyes is consistent in three groups (P = 0.559).The effect of controlling AL elongation of L eyes in group 2B was better than that in group 1 and group 2A (P < 0.001). And the difference between group 1 and group 2A has no statistical significance. (3) The AL difference in H eyes and L eyes decreased from baseline 1.16 ± 0.55mm to 0.88 ± 0.68mm after 1 year in group 1.And in group 2A, the AL difference in H eyes and L eyes decreased from baseline 0.61 ± 0.34mm to 0.48 ± 0.28mm. There was statistically significant difference (all P<0.001). In group 2B, the baseline AL difference in H eyes and L eyes has no significant difference from that after 1 year (P = 0.069).ConclusionsMonocular OK lens is effective on suppression AL growth of the myopic eyes and reduce anisometropia value in unilateral myopic children. Binocular OK lenses only reduce anisometropia with the diopter of the low eye under − 2.00D. Binocular OK lenses cannot reduce anisometropia with the diopter of the low eye equal or greater than − 2.00D. Whether OK lens can reduce refractive anisometropia value is related to the spherical equivalent refractive of low refractive eye in bilateral myopia with anisometropia children after 1-year follow-up.

Purpose To evaluate in a retrospective study the long-term usefulness of red 647 nm krypton and 670 nm diode laser for transscleral contact cyclophotocoagulation (CPC) in the treatment of therapy-resistant inflammatory glaucoma. Methods The authors treated 48 eyes of 38 consecutive patients (mean age 36.8 years, range 6–81 years) with therapy-resistant inflammatory glaucoma secondary to chronic uveitis (45/48), chronic scleritis (1/48), or combined scleritis with keratouveitis (2/48) using transscleral red 647 nm Krypton or 670 nm Diode laser. All eyes had failed maximum tolerated medical therapy and 19/48 (40%) eyes also previous antiglaucoma surgery. Laser power at the scleral surface was 0.35 to 0.45 W and the application time 10 seconds each. The follow-up was 42.8± 40.0 (range 2–145) months. Results The mean preoperative intraocular pressure (IOP) of 35.6±8.1 mmHg fell to 6–21 mmHg level in 75% after one or repeated CPC. Among adult patients this was achieved in 85%, among children in 54%. More than one treatment was needed in 52%. No cases of hypotony, phthisis bulbi, or other devastating complications occurred. Conclusions Transscleral CPC using red 647 nm krypton or 670 nm diode laser is an effective and well-tolerated procedure for the treatment of therapy-resistant inflammatory glaucoma in adults. CPC can be considered before incisional antiglaucoma surgery with a shunt or antimetabolites is undertaken
