ABSTRACT Objectives To investigate the hypothesis that there is difference in the treatment outcomes of milder skeletal Class III malocclusion between facemask and facemask in combination with a miniscrew in growing patients. Materials and Methods Patients were randomly divided into two groups. In one group, the patients were treated with facemask therapy (FM group: 12 males, eight females, average age: 10 years, 5 months ± 1 year, 8 months). In the other group, patients were treated with facemask therapy along with a miniscrew (FM+MS group: 12 males, seven females, average age: 11 years, 1 month ± 1 year, 3 months). A lingual arch with hooks was fixed to the maxillary arch in both groups and a protractive force of 500 g was applied from the facemask to the hooks. The patients were instructed to use the facemask for 12 hours per day. In the FM+MS group, a miniscrew was inserted into the palate and fixed to the lingual arch. Results Mobility and loosening of the miniscrew were not observed during treatment. Lateral cephalometric analysis showed that SNA, SN-ANS, and ANB values were significantly increased in the FM+MS group compared with those for the FM group (SNA, 1.1° SN-ANS, 1.3° ANB, 0.8°). Increase in proclination of maxillary incisors was significantly greater in the FM group than in the FM+MS group (U1-SN, 5.0°). Conclusions During treatment of milder skeletal Class III malocclusion, facemask therapy along with a miniscrew exhibits fewer negative side effects and delivers orthopedic forces more efficiently to the maxillary complex than facemask therapy alone.

ABSTRACT Background No randomized controlled trial has tried to compare early class III treatment outcomes between the removable mandibular retractor (RMR) and the bone-anchored intermaxillary traction (BAIMT). The objective of this study was to evaluate skeletal, dental, and soft-tissue changes following early class III treatment with these two treatment modalities. Materials and methods A parallel group randomized controlled trial was conducted on patients with class III malocclusion, treated at the University of Al-Baath Dental School in Hamah, Syria. Ninetythree children with skeletal class III malocclusion were evaluated and 41 children fulfilled the inclusion criteria. Randomization was performed using computer-generated tables; allocation was concealed using sequentially numbered opaque and sealed envelopes. Thirty-eight participants were analyzed (mean age 11.46 ± 1.28 years). They were randomly distributed into two groups receiving either the RMR or the BAIMT technique with 19 children in each (1:1 allocation ratio). The primary outcome measure was the horizontal movement of points A, B, and Pogonion. Results Point A showed greater anterior movement in the BAIMT group (x̄ = 1.69 mm) than in the RMR group (x̄ = 1.05 mm; p < 0.001). Points B and Pog showed posterior movement in the BAIMT group (x̄ = −3.01 and −2.51 mm respectively) and anterior movements in the RMR group (x̄ = 0.22 and 0.78 mm respectively). Conclusion The BAIMT appeared to be more effective than the RMR in the correction of mild to moderate class III malocclusion in growing patients. Clinical significance Bone-anchored intermaxillary elastics appears to be a promising solution for class III growing patients with mild to moderate degrees of skeletal discrepancy.

ABSTRACT Aims The aim of this randomized controlled trial was to compare the skeletal and dentoalveolar effects of the modified tandem appliance (MTA) vs the facemask (FM) with rapid maxillary expansion. Materials and methods Thirty-two patients, aged 7 to 9 years were recruited. Eligibility criteria included skeletal class III malocclusion that resulted from the retrusion of the maxilla. Randomization was accomplished to divide the sample into two equal groups to be treated with either MTA or FM. Lateral cephalometric radiographs were obtained before treatment and after 2 mm positive overjet was achieved. Intragroup comparisons were performed using paired-sample t-test, and intergroup comparisons were performed using two-sample t-test at the p ≤ 0.05 level. Results Thirty-two patients (16 in each group) were available for statistical analysis. The pretreatment variables of both groups were similar. Both treatment therapies showed similar significant increase in the SNA and ANB angles, accompanied by slight decrease in the SNB angle. The increase in the SN:GoMe angle, Bjork's sum, and the overjet were significantly greater in the FM group. The forward movement of upper dentition was similar in both groups. Although the lower incisors retrusion was significantly greater in the FM group than in the MTA group, the uprighting of the lower molars was significantly greater in the MTA group. Conclusion Both appliances showed similar effects apart from less clockwise rotation of the mandible, less retrusion of the lower incisors, and greater uprighting of the lower molars in the MTA group. Clinical significance Both the MTA and the FM groups are effective in treating class III malocclusion. The MTA group is more efficient in controlling the clockwise rotation and gaining some space in the lower arch. How to cite this article Husson AH, Burhan AS, Salma FB, Nawaya FR.

Nasal packs are widely used after septoplasty and turbinectomy. We conducted a prospective, randomized, controlled clinical trial including 100 patients who underwent septoplasty with/or without turbinectomy randomized into two groups. In the first group (the Merocel group), a standard tampon was inserted at the end of surgery. In the second group (the glove finger group), the tampon was first placed inside a glove finger. The main outcomes measured were pain and bleeding during the postoperative period and during tampon removal. Consumption of pain killers and tranexamic acid were also recorded. The mean visual analog scale score 12 hours after surgery and during tampon removal in the Merocel group were 6.78 and 8.92, respectively, compared to 4.06 and 5.27, respectively, in the glove finger group (p < 0.001). A statistically significant difference in the bleeding rate and tranexamic acid consumption during tampon removal in favor of the Merocel group was shown (p < 0.001). The use of Merocel in a glove finger is significantly less painful, although a higher chance of bleeding is reported. The influence of the surgeon's experience in using this technique needs further investigation.

Objectives: In Laparoscopic surgery placement of primary port is an important step and is often associated with complications. Our objective is to compare the merits and demerits like safety, efficacy of the site, time of entry of the port, per-operative and post-operative complications of infrumbilical (IU) with transumbilical (TU) approach for placement of this port. So on the basis of best clinical evidence get a clinical direction for a better site for placement of primary port. Study Design: A prospective randomized controlled trial of 238 patients. Setting: Surgical unit II of DHQ Hospital/ Sargodha Medical College (University of Sargodha) Sargodha. Period: June 2015 to December 2017. Material & Methods: Patients aged 16-70 years, fit for surgery, under general anesthesia were included in this study after informed consent. Patients who were unfit for general anaesthesia, who were Imuno-compromised, diabetics, CLD, with ascites, patients with suspected malignancy, with previous surgery in the umbilical region like midline laparotomy scar, previous hernia repair in this region were excluded from this study. Permission was sought from and granted by institutional ethical committee. Results: A total number of 238 patients were included. Group A (Trans-Umbilical) and Group B (Infra-Umbilical) contained 119 cases each. There were 147 female and 91 male. (M: F ratio of 1: 1.615). Conclusion: Based on results from this study and previous literature, it may be concluded that Transumbilical (TU) placement of primary port for creation of pneumoperitoneum is superior to infrumbilical (IU) approach.

Summary Background Pushing Splints 3 (PS3) device was recently introduced for the treatment of Class III malocclusion in children. Objectives To assess the effect on the sagittal maxillary position (SNA, primary outcome) of PS3 therapy compared with rapid maxillary expansion and facemask therapy (RME/FM) and to compare skeletal and dento-alveolar effects in growing Class III patients. Trial design This trial was a single-centre randomized controlled trial with two groups randomly allocated in a 1:1 ratio of equal size by sealed-envelope randomization, conducted at the Dentistry Unit of Bambino Gesù Children’s Hospital, IRCCS (Rome, Italy). Methods A total of 48 patients with Class III malocclusion were included in the study and randomly allocated to the two groups: PS3 therapy and RME/FM therapy. Only the RME/FM group underwent palatal expansion, and both groups were instructed to wear the appliances 14 hours/day. Pre- (T0) and post-treatment (T1) cephalograms were taken. An independent sample t-test and regression analysis were used to analyse the data (P value &lt;0.05). Researchers involved in statistics and tracings were blinded to the treatment allocation. Results A total of 42 patients (21 for each group) completed the study. The maxillary sagittal position improved similarly in both groups (SNA = 0.4°; P = 0.547). A statistically significant decrease of SNPg angle (−1.6°; P &lt; 0.001) and increase of ANPg angle (1.4°; P = 0.018) were found in the RME/FM group compared with PS3 group. CoGoMe angle significantly decreased in RME/FM group compared with PS3 group (−1.7°; P = 0.042). The regression analysis showed an association between SN/MP angle at T0 and the differences between T1 and T0 of SNPg (B = 0.13; P = 0.005) and SN/MP (B = −0.19; P = 0.034). Only three patients (PS3 = 2; RME/FM = 1) had breakages of the devices. Limitations Results are limited to short-term effects. Conclusion RME/FM therapy and PS3 are both effective therapies for the early correction of Class III malocclusion. The PS3 controlled better mandibular divergency reducing the clockwise rotation in patients with higher mandibular inclination. Registration This study was not registered in a clinical trial registry.

Nasal Septoplasty

Background: Successful local anaesthesia is of critical importance for the success of septoplasty, and many surgeons prefer to use cocaine for this purpose. The aim of this study was to evaluate the efficacy of cocaine 4 per cent solution, compared with tetracaine 2 per cent plus adrenaline, as a local anaesthetic for patients undergoing septoplasty.Methods: From December 2002 to February 2005, a prospective, randomized, controlled trial was conducted. One hundred and eight patients underwent septoplasty under local anaesthesia. Patients were randomly classified into group A and group B, in which was used respectively cocaine 4 per cent solution and tetracaine 2 per cent solution plus adrenaline. A visual analogue scale was used to evaluate the severity of patients' pain during their procedure.Results: Group B (tetracaine; mean rank=43.77) reported significantly less pain (p<0.001) compared with group A (cocaine; mean rank=65.23).Conclusions: On the basis of these findings, we recommend tetracaine as the first choice anaesthetic for nasal septoplasty; the use of cocaine should be limited.
