RESUMEN

Failure in the eruption of the maxillary incisor necessitates a precise diagnosis and treatment regimen. Impaction can have a number of causes such as physical obstacles in the eruption path, discrepancy in the length of the dental arch, and tooth anomaly. Delayed eruption of anterior teeth can result in a number of issues such as malocclusion and psychological discomfort. In many cases, if the intervention is not done at an early stage, complex orthodontic intervention is required after surgical exposure to enable appropriate eruption. This case report is of a nine-year-old child with unerupted maxillary central incisors. The child was treated surgically for incisor exposure under general anesthesia (GA). Both functional and aesthetic considerations made this surgical procedure necessary. GA was administered due to the negative behavior of the child in a dental setting. Hence, it ensured patient comfort and cooperation. Follow-up examinations showed satisfactory progress in the eruption of the teeth with no complications.

RESUMEN

As the thumb is pronated, primary repair of complex injuries may be more difficult than the repair of other digits. We describe a simple technique that facilitates thumb repair. We insert a Kirschner wire perpendicular to the bone axis in the middle of the proximal phalanx, which ensures adequate exposure of the palmar aspect without the need for thumb position adjustment by an assistant. This technique is particularly useful when inexperienced surgeons perform thumb replantation and primary flexor tendon repair using a multistrand suture technique.

RESUMEN

INTRODUCTION: Maxillary anterior teeth that have not erupted may substantially alter the appearance of the teeth and face. Orthodontists often encounter a clinical challenge while dealing with an impacted maxillary incisor, which creates space problems in the anterior region. The purpose of this paper is to describe the well-synchronized orthodontic and surgical treatment of a horizontally impacted maxillary central incisors. CASE PRESENTATION: A male patient, aged 27, presented with a complaint of unerupted two maxillary front teeth. This resulted in the displacement of adjacent teeth into the vacant region. An intraoral examination revealed a Class II molars on both sides, a deep curve of the space with a 2.3 mm overjet, and an edge-to-edge bite of 0.1 mm. The 3D cone beam computed tomography (CBCT) imaging unveiled a labial impacted and a rotation of approximately 90 degrees (horizontal impacted) on both central maxillary incisors. DISCUSSION: The self-ligating bracket was installed and orthodontic traction aligned the affected tooth in the dental arch. To reach the labial surface of the impacted incisor, open surgical exposure by window excision of soft tissues with a laser was preferable due to the large bulge in the sulcus. Because self-ligating bracket systems employed modest pressures to position the maxillary right central incisor in the arch, the window surgical technique did not produce gingival scarring or increased clinical crown length. CONCLUSION: The impacted upper central incisor was successfully treated using a collaborative interdisciplinary (surgical-orthodontic) approach, which resulted in a favorable aesthetic and functional outcome.

RESUMEN

OBJECTIVE: Although keyhole transorbital approaches are gaining traction, their indications have not been adequately studied comparatively. In this study the authors have defined them also as transwing approaches-meaning that they use the different facies of the sphenoid wing for cranial entry-and sought to compare the four major ones: 1) lateral orbitocraniotomy through a lateral canthal incision (LatOrb); 2) modified orbitozygomatic approach through a palpebral incision (ModOzPalp); 3) modified orbitozygomatic approach through an eyebrow incision (ModOzEyB); and 4) supraorbital craniotomy through an eyebrow incision (SupraOrb), coupled with its expanded version (SupraTransOrb). METHODS: Cadaveric dissections were performed at the neuroanatomy lab. To delineate the skull base exposure, four formalin-fixed heads were used, with two sides dedicated to each approach. The outer limits were assessed via image guidance and were mapped and illustrated accordingly. A fifth head was dissected purely endoscopically, just to facilitate an overview of the transwing concept. Qualitative features were also rigorously examined. RESULTS: The LatOrb proves to be more versatile in the middle cranial fossa (MCF), whereas the anterior cranial fossa (ACF) exposure is limited to a small area above the sphenoid ridge. An anterior clinoidectomy is possible; however, the exposure of the roof of the optic canal is suboptimal. The ModOzPalp adequately exposes both the ACF and MCF. Its lateral trajectory allows the inferior to superior view, yet there is restricted access to the medial anterior skull base (olfactory groove). The ModOzEyB also provides extensive exposure of the ACF and MCF, but has a more superior to inferior trajectory compared to the ModOzPalp, making it more appropriate for pathology reaching the medial anterior skull base or even the contralateral side. The anterior clinoidectomy is performed with improved visualization of the optic canal. The SupraOrb provides mainly anterior cranial base exposure, with minimal middle fossa. An anterior clinoidectomy can be performed, but without any direct observation of the superior orbital fissure. Some MCF access can be accomplished if the lateral sphenoid wing is drilled inferiorly, leading to its highly versatile variant, the SupraTransOrb. CONCLUSIONS: All the aforementioned approaches use the sphenoid wing as skull base corridor from a specific orientation point; hence these are designated as transwing approaches. Their peculiarities mandate careful case selection for the effective and safe completion of the surgical goals.

RESUMEN

OBJECTIVE: The lateral aspect of the cerebellomesencephalic fissure frequently harbors vascular pathology and is a common surgical corridor used to access the pons tegmentum, as well as the cerebellum and its superior and middle peduncles. The quadrangular lobule of the cerebellum (QLC) represents an obstacle to reach these structures. The authors sought to analyze and compare exposure of the cerebellar interpeduncular region (CIPR) before and after QLC resection and provide a case series to evaluate its clinical applicability. METHODS: Forty-two sides of human brainstems were prepared with Klingler's method and dissected. The exposure area before and after resection of the QLC was measured and statistically studied. A case series of 59 patients who underwent QLC resection for the treatment of CIPR lesions was presented and clinical outcomes were evaluated at 1-year follow-up. RESULTS: The anteroposterior surgical corridor of the CIPR increased by 10.3 mm after resection of the QLC. The mean exposure areas were 42 mm2 before resection of the QLC and 159.6 mm2 after resection. In this series, ataxia, extrapyramidal syndrome, and akinetic mutism were found after surgery. However, all these cases resolved within 1 year of follow-up. Modified Rankin Scale score improved by 1 grade, on average. CONCLUSIONS: QLC resection significantly increased the exposure area, mainly in the anteroposterior axis. This surgical strategy appears to be safe and may help the neurosurgeon when operating on the lateral aspect of the cerebellomesencephalic fissure.

RESUMEN

Background/purpose: Impaction of permanent second molar (PM2) is found occasionally. This study tried to explore the risk factors associated with the impacted PM2 teeth and show how to use different treatment modalities to correct the impaction of PM2 teeth. Materials and methods: This study used three cases of PM2 impaction to show how to identify the risk factors of PM2 impaction and how to remove these risk factors to facilitate the eruption of impacted PM2 teeth to the correct occlusal positions. Results: The first and second cases both showed delayed eruptions of two maxillary PM2 teeth. After resection of the dense fibrotic gingival tissues on the tooth eruption pathway, these two impacted maxillary PM2 teeth finally erupted to the normal occlusal positions by their inherent tooth eruption potential. The second case also had mesioangular impaction of two mandibular PM2 teeth. After odontectomy of teeth 38 and 48, the two impacted mandibular PM2 teeth also erupted to the normal occlusal positions by their inherent tooth eruption potential. The third case had impaction of teeth 17, 27 and 47. After extraction of four third molars and four selected premolars, orthodontic mesialization of four permanent first molars, and orthodontic traction using a mini-screw, the three impacted teeth finally erupted to the normal occlusal positions. Conclusion: We conclude that after removing the obstacles on the tooth eruption pathway, the impacted PM2 teeth usually can erupt to their normal occlusal positions by their inherent tooth eruption potential with or without the assistance of orthodontic traction.

RESUMEN

This case study offers a rare and difficult condition involving the impaction of teeth 11, 12, and 13, providing a severe dental challenge. A thorough examination was performed on the patient, which included clinical evaluations and radiographic examinations. Because the impacted teeth were causing discomfort and functional impairment, a multidisciplinary approach was required, which included surgical exposure followed by traction forces to level and align the impacted teeth. The abstract emphasizes the case's complexity, digging into the diagnosis process and the establishment of a personalized treatment strategy. The complexities of handling many impacted teeth are explored in length, including surgical intervention, orthodontic considerations, and postoperative care.

RESUMEN

Although impaction of the maxillary permanent central incisor is uncommon in dentistry due to its significance to facial aesthetics which are challenging to treat. To abstain from the consequences related to aesthetic and functional occlusion, early detection of an impacted central incisor is imperative. This case report describes a male patient, aged 22 years, who had an impacted central incisor tooth in the maxillary anterior region. A surgery was performed to remove the impacted supernumerary tooth that was preventing the eruption of the central incisor. Using a combination of surgical exposure and orthodontic force, the impacted right maxillary central incisor was relocated to its proper occlusion in the dental arch.

RESUMEN

BACKGROUND: Our study examined if there were any limitations when using various measurement techniques in the literature to quantify osseous exposure. Additionally, we also examined if surface contour had any influence on obtained measurements, which no previous study has attempted. MATERIALS AND METHODS: Three methods used to quantify osseous exposure area were identified, one in which involves manually applying mesh over exposure area. The other two use digital image capture software (ImageJ, Bethesda, MD). We simulated flat, convex, and mixed surface types using synthetic bone analogs. We assessed the degree of variability between mean values using an ANOVA or Kruskal-Wallis equality of populations rank test. Cronbach's alpha test of internal reliability was used to assess the internal reliability of measurement technique. RESULTS: ANOVA test for difference in measurement techniques on all three surface types was statistically significant (p < 0.05). Cronbach's alpha test of internal reliability for each technique on the convex surface did not obtain adequate significance (alpha >0.70). Only the mesh method obtained adequate alpha value for significance when applied to the flat and mixed surface types. DISCUSSION: Each of the three measurement techniques tested demonstrated poor internal reliability. We suggest taking care when comparing studies that use different quantification techniques when calculating osseous exposure for different surgical approaches. Future studies should explore alternative methods of osseous exposure quantification.

RESUMEN

AIM: The purpose of this study was to compare the three various techniques for measuring the alveolar ridge's dimensions prior to implant insertion. MATERIALS AND METHODS: For this study, a total of 36 participants were chosen. To prepare a surgical stent, a study model was created from an alginate impression. A first point (reference point) was marked on the crest of the ridge in relation to the adjacent teeth. Then, one point (point 1) and another point (point 2) were marked at distances of 3 and 6 mm, respectively, from the reference point. Based on the procedure for measuring the size of the alveolar ridge, the study was divided into the following groups. Group I: Cone-beam computed tomography (CBCT) measurement method; Group II: Ridge mapping measurement method; Group III: Direct caliper measurements method. Descriptive statistics were used to estimate the mean and standard deviation (SD). The Student's unpaired t-test was utilized for the statistical analysis. The 5% level of significance was used. RESULTS: There was no significant difference found between CBCT with ridge mapping and direct caliper measurements. However, on comparison of ridge mapping and direct caliper measurements technique, at point 1, the ridge mapping was 3.88 ± 0.12 and the direct caliper measurement was 3.62 ± 0.08. At point 2, the ridge mapping was 6.58 ± 0.06 and the direct caliper measurement was 6.32 ± 0.04. There was a statistically significant difference found between these two measurement methods. CONCLUSION: Within the limitation, the current study came to the conclusion that when CBCT and ridge mapping measurements were individually compared with the gold standard-the surgical open method, CBCT-demonstrated to be a highly specific and sensitive method for detecting the residual alveolar ridge width in the treatment planning of dental implants. CLINICAL SIGNIFICANCE: Evaluation of alveolar bone is necessary during treatment planning for dental implant placement. Using simply panoramic and/or periapical radiographs to evaluate the bone may not be sufficient because it only provides two-dimensional information regarding the implant locations. Therefore, for better implant placement, three-dimensional information of the implant site, such as CBCT and ridge mapping technique, should be assessed.

RESUMEN

Our purpose was to evaluate the efficacy of lateral canthotomy, sub-tenon anesthesia injection, and the use of modified speculum for gaining adequate surgical exposure during surgery for retinopathy of prematurity (ROP). Fourteen eyes of 10 consecutive patients undergoing microincisional vitrectomy surgery (MIVS) for stage 4 and stage 5 ROP were included. There was a significant widening of the palpebral fissure height and length using this technique. No patient developed a lens injury during the surgery. All the canthotomy incisions completely healed at a four-week follow-up visit. This is a safe and effective technique for increasing surgical exposure in cases of ROP requiring vitrectomy.

RESUMEN

BACKGROUND: Maxillary incisor and canine teeth are commonly impacted and require multidisciplinary treatment to accommodate them in the dental arch. OBJECTIVES: To assess the periodontal outcomes of impacted maxillary central incisor and canine teeth, which have been successfully aligned in the arch following surgical exposure and orthodontic traction with fixed appliance therapy. SEARCH METHODS: Systematic literature searches without restrictions were undertaken in eight databases. SELECTION CRITERIA: Studies reporting surgical interventions in combination with orthodontic traction with fixed appliance therapy to align impacted maxillary incisors or canines published up to January 2023. DATA COLLECTION: Duplicate independent study selection, data extraction, and risk of bias assessment. ANALYSIS: Random-effects meta-analyses of aggregate data. RESULTS: Twenty-three studies (21 retrospective and 2 prospective) were included in the final analysis. Three studies reported outcomes for maxillary central incisors and 20 reported outcomes for maxillary canines. For maxillary central incisors, all three studies were rated as being at moderate risk of bias. For maxillary canines, 17 studies and 1 study were rated at moderate and high risk of bias, respectively. Both prospective studies were rated at a low risk of bias. Meta-analyses comparing aligned impacted maxillary canines to their non-impacted contralateral counterparts found the former had increased Plaque Index scores (mean difference [MD] 0.19; 95% confidence interval [CI] 0.03, 0.35; P = 0.03), increased clinical attachment loss (MD 0.40 mm; 95% CI 0.17, 0.63; P = 0.01), increased pocket probing depth (MD 0.18 mm; 95% CI 0.07, 0.28; P = 0.001), increased bone loss (MD 0.51 mm; 95% CI 0.31, 0.72; P < 0.001), and reduced keratinized gingival width (MD -0.31 mm; 95% CI -0.61, -0.01; P = 0.04). CONCLUSIONS: Limited evidence suggests that surgical exposure and orthodontic alignment of impacted maxillary central incisor or canine teeth, results in modest adverse effects in the periodontium. These findings should be viewed with caution as our certainty for these outcomes is very low to low due to the bias and heterogeneity. Further well-conducted studies reporting patient centred outcomes are required. REGISTRATION: PROSPERO (CRD42020225639).

RESUMEN

BACKGROUND: Although the widespread cone-beam computed tomography (CBCT) is a diagnosing tool for impacted canines, the surgical exposure-based diagnostic accuracy of this 3D imaging modality has not been established yet. Therefore this study aimed to (1) compare the accuracy of CBCT- and 2D-based interpretations of impacted canine and its relationships with the neighbouring structures with the gold standard (GS) readings, (2) and calculate the diagnostic accuracy, sensitivity, and specificity values of the variables assessed using CBCT and 2D methods. MATERIAL AND METHODS: Patients with unilateral impacted maxillary canines (IMCs) planned for surgical extraction between 2016-2018 were checked in-depth to include in this cross-sectional study. For each patient, 2D and 3D radiographic records were obtained and assessed by eight postgraduate orthodontic students. These assessments were compared with the GS readings based on surgical exposure and direct vision of the IMCs. To compare 2D- and CBCT-based assessments with the GS values, Cochran's Q tests, Friedman's tests, McNemar's, McNemar-Bowker's, and Wilcoxon tests were applied. RESULTS: A total of 17 patients (6 males, 11 females; mean age: 20.52±3.98 years) were randomly selected and included in this study. Significant differences were found between the CBCT-based assessments and the GS only concerning shape and bony coverage of the IMC (P=0.001 and P<0.001, respectively). On the contrary, there were significant differences between the 2D-based assessments and the GS regarding all the assessed variables except for the ankylosis and the proximity to the adjacent teeth (P=0.424, and P=0.080, respectively). CBCT-based assessments had remarkably higher values of diagnostic accuracy, sensitivity, and specificity compared to 2D-based ones. CONCLUSIONS: The diagnostic accuracy of CBCT outperformed 2D radiography in localizing the IMC (labiopalatal, mesiodistal, and vertical location), detecting root apex development of the IMCs, and the resorption of the adjacent incisors. Although both 2D and 3D techniques showed the same ability in the diagnosis of IMCs ankylosis, the diagnostic accuracy of CBCT was superior. However, both techniques inaccurately determined the shape of the impacted canine and the bony coverage.

RESUMEN

INTRODUCTION: The negative perceptions and lack of exposure to surgery and the operating room (OR) have been known to divert students away from surgical specialties. This study describes the impact of a surgical subspecialty exposure event (OR Essentials), combined with surgical faculty and M4 mentorship on preclinical medical students' confidence at an academic medical center. METHODS: OR essentials event teaches surgical skills to preclinical medical students through hands-on skill-based workshops in a simulated OR setting. Pre and postevaluations were administered to measure program impact. RESULTS: One hundred four preclinical medical students participated. Following OR essentials, students reported a significant increase in confidence in the OR (P < 0.0001) and in basic surgical skills (P < 0.0001). CONCLUSIONS: Early surgical exposure events like OR essentials provide opportunities to improve medical student confidence in the OR, which will hopefully support recruitment of future surgeons.

RESUMEN

OBJECTIVES: To summarize the open-eruption technique of impacted anterior maxillary teeth, this study reports a technically improved operation on surgical exposure based on dental follicles and evaluates post-treatment periodontal health considering the effect of dental follicles. METHODS: Patients who underwent open-eruption technique with unilateral labially impacted maxillary central incisors were selected. The impacted teeth were assigned to the experimental group, and the contralateral unimpacted maxillary central incisors were assigned to the control group. In the surgical exposure, the new technique makes use of dental follicles to manage the soft tissue, so as to preserve soft tissue for better aesthetic results and healthier periodontal tissue. Tooth length, root length, alveolar bone loss, and alveolar bone thickness were recorded after the therapy. RESULTS: A total of 17 patients with unilateral maxillary central incisor impaction were successfully treated. The tooth length and root length of the two groups showed a statistically significant difference between the impacted and homonym teeth, with a shorter length in the impacted tooth (P<0.05). More labial alveolar bone loss was found in the experimental group compared with that in the control group (P<0.05). The outcomes of the cementoenamel junction width, pa- latal alveolar bone loss, and alveolar bone thickness did not indicate statistical significance between the experimental and control groups (P>0.05). CONCLUSIONS: In the surgical exposure, the new technique uses dental follicles to manage the soft tissue and preserve it for better aesthetic results and healthier periodontal tissues.

RESUMEN

BACKGROUND: The deltopectoral approach is well accepted for shoulder arthroplasty procedures. The extended deltopectoral approach with detachment of the anterior deltoid from the clavicle allows increased joint exposure and can protect the anterior deltoid from traction injury. The efficacy of this extended approach has been demonstrated in anatomic total shoulder replacement surgery. However, this has not been shown in reverse shoulder arthroplasty (RSA). The primary aim of this study was to evaluate the safety of the extended deltopectoral approach in RSA. The secondary aim was to evaluate the performance of the deltoid reflection approach in terms of complications and surgical, functional, and radiologic outcomes up to 24 months after surgery. METHODS: A prospective, nonrandomized comparative study was performed between January 2012 and October 2020 including 77 patients in the deltoid reflection group and 73 patients in the comparative group. The decision for inclusion was based on patient and surgeon factors. Complications were recorded. Patients were followed up for ≥24 months to evaluate their shoulder function and undergo ultrasound evaluation. Functional outcome measures included the Oxford Shoulder Score, Disabilities of the Arm, Shoulder and Hand score, American Shoulder and Elbow Surgeons score, pain intensity (rated on visual analog scale [VAS] from 0 to 100), and range of motion (forward flexion, abduction, and external rotation). A regression analysis was performed to evaluate any factors of influence on the VAS score. RESULTS: There were no significant differences in the complication rate between the 2 groups (14.5% in deltoid reflection group and 13.8% in comparative group, P = .915). Ultrasound evaluation was available in 64 patients (83.1%), and no proximal detachment was observed. In addition, there were no significant differences in functional outcome measures both preoperatively and at 24 months after surgery between the groups assessed based on the mean VAS pain score, Oxford Shoulder Score, Disabilities of the Arm, Shoulder and Hand score, American Shoulder and Elbow Surgeons score, forward flexion, abduction, and external rotation. Adjustment for possible confounders in a regression model indicated that only prior surgery significantly influenced the VAS pain score after surgery (P = .031; 95% confidence interval, 0.574-11.67). Deltoid reflection (P = .068), age (P = .466), sex (P = .936), use of glenoid graft (P = .091), prosthesis manufacturer (P = .382), and preoperative VAS score (P = .362) were not of influence. DISCUSSION: The results of this study show that an extended deltopectoral approach for RSA is safe. Selected reflection of the anterior deltoid muscle improved exposure and prevented anterior deltoid muscle injury followed by reattachment. Patients had similar functional scores preoperatively and at 24 months postoperatively compared with a comparative group. Furthermore, ultrasound evaluation showed intact reattachments.

RESUMEN

Developing adequate exposure when performing a revision total knee arthroplasty is critical to an efficient and safe intraoperative course. Proper planning and knowledge of the relevant anatomy are important when dissecting scar tissue associated with previous trauma or surgery and navigating bone loss. We present a review of the different total knee arthroplasty extensile exposure techniques that have been described in the literature. Specific exposures discussed include the femoral peel, banana peel, medial epicondylar osteotomy, quadriceps snip, tibial tubercle osteotomy, wandering resident, and the V-Y quadricepsplasty with patella turndown. Furthermore, we review the histological healing potential, biomechanical principles that drive post-operative expectations, post-operative rehabilitation protocols, and reported functional outcomes of each technique.

RESUMEN

Deposition of the maxillary permanent central incisor is a rare occurrence in dental practice. It is a difficult condition to treat due to its importance to facial esthetics. If complications are to be avoided, early detection of such teeth is important. The present case report of impacted maxillary central incisor encased within an abnormally thickened labial frenulum. A 9-year-old boy, came with his parents to the Pediatric Dentistry Specialist, Dental and Oral Hospital, Airlangga University (UNAIR) with a chief complaint that his left maxillary front teeth did not grow while his right front teeth had grown perfectly. From the anamnesis, the patient had experienced a falling trauma when he was young, which caused the deciduous tooth to fall out. Good general health, no history of allergies, and no medical history of case management. This is a fixed orthodontic treatment with surgical exposure of impacted teeth and frenectomy of labial frenulum. After the crown of the impacted incisor was surgically exposed, eruption ball chain was bonded to traction the incisor. The left maxillary incisor fully erupted and normally to percussion, mobility, and sensitivity testing with good attached gingiva in the next 9 months. Management abnormality of labial frenulum in this case with frenectomy by using electrocautery for minimalized trauma in children. Fixed orthodontic therapy was continued to achieve proper alignment leading to good esthetic and functional rehabilitation. The treatment of an unerupted tooth will depend on its state, position, and presence of enough space in the dental arch to accommodate.
