This study aimed to provide an external validation of morphometric outcomes, including recently developed parameters — vertico-longitudinal index (VLI) and vertex-nasion-opisthocranion (VNO) angle — along with a proposed stratification system for nonsyndromic sagittal craniosynostosis (NSC). Thin-cut CT scans performed before and after total calvarial remodeling in 70 NSC children (mean preoperative age, 7.0 months; mean postoperative age 23.8 months) were evaluated. The parameters, including linear dimensions, morphometry-based indices, and cranial angles, were measured at the cranial vault and base. Each patient was also assigned a scaphocephaly severity score (SSS). The obtained data were compared with an age-matched control group of 80 normocephalic children.
After surgery, all dimensions of the cranial vault increased, but did not normalize (p < 0.0001). Contrarily, some normalization was noted in the skull base, within the anterior and posterior cranial fossae. Postoperative results confirmed the diagnostic cut-off level for VNO at 50°; however, the proposed VLI cut-offs skewed the accuracy of SSS in the control group.
To the best of our knowledge, this study was the first to discuss the value of an NSC stratification system in relation to underlying components. The SSS has a relevant background, but its accuracy would increase with a redefinition of normative VLI ranges.

The aim of this narrative style review is to clarify the role of TMJ surgery in the management of specific TMJ disorders by introducing a simple and practical surgical classification. A decade ago, a new surgical classification was published which, like the Wilkes classification, included the five escalating degrees of joint pathology, but with more practical definitions and proposed surgical options for each of the disease categories. The classification begins with Category 1 — painful but otherwise structurally normal joints, which are largely managed nonsurgically. Categories 2 and 3 denote reducing and nonreducing disc displacement of the TMJ, respectively, with the former treated by TMJ arthrocentesis or level 1 arthroscopy and the latter best managed with disc repositioning or discopexy. Category 4 describes degenerative changes to the disc itself, where the disc cannot be salvaged and is thus removed with TMJ discectomy. Lastly, Category 5 refers to end-stage joint disease, where none of the joint components can be salvaged; both the disc and condylar head are sacrificed, and the TMJ is reconstructed with a prosthetic total joint replacement. In the decade since its publication, various studies have served to validate the usefulness of the TMJ surgical classification, and how it can be applied to better understand the role of TMJ surgery in everyday clinical practice.

Purpose
This preliminary study aimed to assess the efficacy of zygomatic buttress bone grafting for nasal floor augmentation in patients with a unilateral alveolar cleft who were referred after the optimal timetable for this surgery had elapsed.
Case series
Five patients, aged 12–18 years, with unilateral alveolar clefts were treated at Qaem Hospital, Mashhad, Iran. Initially, a mucous layer was established on the side of the cleft nose, followed by forming a bony bridge between the defect's sides through a bone graft derived from the zygomatic buttress and xenograft bone powder. Subsequently, the grafted region was covered with an absorbable collagen membrane, and the oral-side flap was sealed. Post-operative follow-ups occurred at 1 week, 1 month, and 3 months, and cone beam computed tomography (CBCT) was performed 6 months post-treatment. Discrepancy between the anterior edge height of the pyriform aperture on the healthy and cleft sides post-grafting was assessed. The average disparity between the height of the anterior edge of the pyriform aperture on the healthy side and the peak height achieved post-grafting on the cleft side was 1.90 ± 2.82 mm.
Conclusion
Within the limitations of the study, it seems that zygomatic buttress is applicable for late unilateral alveolar bone grafting as an intraoral source, and is helpful in symmetric bony nasal floor reconstruction, with a good success rate.

To search for the best available scientific evidence in relation to the reported overall and selective complication rates for arthroscopic surgery in patients presenting with internal derangement (ID) of the temporomandibular joint (TMJ).
A comprehensive electronic search was conducted without data or language restrictions up to August 2023. Inclusion criteria were the following: study in humans, randomized or quasi-randomized controlled trials (RCTs), controlled clinical trials (CCTs), cohort studies and series of clinical cases. The proposed PICOS question was: “In clinical trials and retrospective clinical series of patients treated by arthroscopy, which were the overall and selective complication rates?” Exclusion criteria were animal studies, review papers, technical reports, and in vitro studies. The Cochrane Collaboration Tool was used to assess the risk of bias of the included studies in terms of their quality. The Strength of Recommendation Taxonomy (SORT) classification was used to determine the level of evidence of the selected studies.
A total of 498 studies were identified. Of these, 16 studies fulfilled the inclusion criteria and were selected for qualitative assessment. Temporary 5th nerve deficit, ranging from 0.15% to 2.38%, was reported to occur in most larger series, comprising 7394 operated joints. Temporary 7th nerve paresis was reported to occur in 0.21%–0.7% in the largest series, comprising 6866 operated joints. Partial hearing loss was reported in 6 studies, ranging from 0.21% to 2.2% in 5845 operated joints. Edema of surrounding soft tissues, including parapharyngeal, soft palate and/or preauricular edema was reported in 8 studies, with complication rates ranging from 2% to 17.9% in 2274 operated joints. Laceration of the EAC was reported in 8 studies involving 2665 operated joints, with complication rates ranging from 0.3% to 6%. A total of 872 complicated events among 11,304 operated joints were reported, accounting for an overall complication rate of 7.71%.
Complications from arthroscopic procedures have been inconsistently reported, but there are a small number of retrospective studies with well-reported complications rates. As overall complication rate accounts for less than 8% of the cases, arthroscopy seems to be a highly safe procedure for the treatment of internal derangement (ID) of the TMJ. Due to the absence of studies with high evidence, information for patients about complications should be based on clinical series of cases.

It was the aim of the study to analyze the distribution and pattern of facial fractures following e-scooter trauma.
Prospective audit data of facial fractures were retrospectively collected to investigate the impact of e-scooter hire, specifically in the form of facial fractures associated with their use. Data collected included patient demographics, mode of injury, date of injury, facial bones involved, presence of soft tissue injury, and factors associated with injury, including intoxication and helmet use.
A total of 849 patients were treated for facial fractures during the study period, of which 34 were attributed to e-scooter use. One-half of those injured riding e-scooters were intoxicated, and one-quarter were wearing helmets. There have been an increasing number of facial fractures associated with e-scooter use following the start of the shared e-scooter trial. Zygomaticomaxillary complex fractures were the most common pattern of facial fracture seen.
Most patients required surgical management of their injuries. Policymakers should consider how to improve the enforcement of current regulations, given the healthcare cost associated with the management of these preventable injuries.

Graves-Basedow's disease (GBD) is an autoimmune pathology that affects the thyroid and is characterized by the presence of goiter, hyperthyroidism, ophthalmopathy, and dermopathy. Graves-Basedow ophthalmopathy (GBO) is a set of inflammatory and infiltrative alterations of the orbital tissue that affects 40–90% of subjects suffering from GBD. Our study aims to investigate the differences in the clinical outcomes of patients treated with two different techniques: the classic open and the more modern endoscopic. A retrospective clinical study was carried out from the year 2011 until the year 2020 to evaluate the clinical outcomes of two different surgical techniques for the treatment of GBO. Eighteen patients were given surgical indications, 12 males and 6 females aged between 37 and 69 years (average age 48.5 years), for a total of 36 orbits. From the year 2011 to the year 2014, all patients were treated with the open orbital decompression technique; from 2015 onwards, patients were subjected to orbital decompression with the endoscopic transnasal approach. Pre- and postoperative ophthalmometry, reduction of proptosis, and reduction of oculo-orbital index were compared for the two techniques. As evidenced by the statistical analysis carried out on the sample before and after surgical treatment, there is a statistically significant difference between ophthalmometry and the Oculo-Orbital Index (IOO) values; this indicates that surgical orbital decompression with two walls (floor and medial wall) is effective in reducing exophthalmos. The positive result is also confirmed by the reduction of proptosis, measured in millimeters, averaging 1.7 mm. In the analysis of data relating to the two different patient groups, treated respectively with endoscopic orbital decompression (Technique 1) and classical open orbital decompression (Technique 2), the results obtained show that there is no statistically significant difference between the results of the two techniques. Therefore, the choice of surgical approach is at the discretion of the surgeon. It is our opinion that orbital decompression with the endoscopic transnasal technique should be an absolute indication in all patients who have clinical and radiographic signs of involvement of the optic nerve at the orbital apex (crowded apex syndrome) thanks to the ability of this technique to add and decompress the optical channel at the apex. For all other patients with GBO, the endoscopic technique of orbital decompression can be indicated as a first-line surgical approach considering the absence of skin scars and the best aesthetic results.

Aim
The aim of this study was to examine particular single-nucleotide polymorphisms (IL-1A-889 C/T — rs1800587, IL-1B +3953 C/T — rs 1143634) of interleukins 1A and 1B in the development and prognosis of medication-related osteonecrosis of the jaw.
Materials and methods
DentiGen Parodontitis Tests were applied for collecting samples. This test is suitable for sampling oral mucosa cells in order to detect interleukins 1A and 1B single nucleotide polymorphisms (IL-1A−889, IL-1B+3953). Genetic samples were evaluated in the Istenhegyi Genediagnostic Center using the DNA-hybridization method.
Genetic samples were collected in the patient group and the control group. The role of gene polymorphisms in the development of the disease was investigated by comparing the genetic results for the patient and control groups. The investigation of gene polymorphisms in disease prognosis is based on stage improvement, recovery, and relapses following treatment.
Results
In total, 91 patients with MRONJ and 59 healthy controls were included in the study. 51 patients in the patient group and 37 controls had unfavorable allelic variants. No association (Mp = 1.42, SDp = 0.496, Mc = 1.35, SDc = 0.482, p = 0.52) was found between unfavorable polymorphisms and the development of the MRONJ. In the patient group, surgical therapy was required in 79 cases. Stage improvement was detected in 78 cases, recovery in 67 cases, and relapse in 33 cases. No stage improvement was found in one case, recovery in nine cases, or relapse in 34 cases. Of the 79 patients requiring surgical therapy, 49 had unfavorable allelic variants. No connection was found between the polymorphisms examined and stage improvement (Mp = 1.37, SDp = 0.486, Mnp = 2, SDnp = –, p = 0.800) or recovery (Mp = 1.39, SDp = 0.491, Mnp = 1.44, SDnp = 0.527, p = 0.990). However, a significant association (Mp = 1.21, SDp = 0.415, Mnp = 1.58, SDnp = 0.502, p < 0.001) was found between relapses and the presence of unfavorable allelic variants.
Conclusion
Within the possible limitations of this study, it can be assumed that the analysis of certain single-nucleotide polymorphisms of interleukin-1 may have the potential to help define the risk stratification of MRONJ after surgical therapy.

However, a significant association (Mp = 1.21, SDp = 0.415, Mnp = 1.58, SDnp = 0.502, <em>p</em> < 0.001) was found between relapses and the presence of unfavorable allelic variants.</div></div><div><h3>Conclusion</h3><div>Within the possible limitations of this study, it can be assumed that the analysis of certain single-nucleotide polymorphisms of interleukin-1 may have the potential to help define the risk stratification of MRONJ after surgical therapy.</div></div>","PeriodicalId":54851,"journal":{"name":"Journal of Cranio-Maxillofacial Surgery","volume":"52 10","pages":"Pages 1133-1139"},"PeriodicalIF":2.1,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141409110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apert (AS), Crouzon (CS), Muenke (MS), Pfeiffer (PS), and Saethre Chotzen (SCS) are among the most frequently diagnosed syndromic craniosynostoses. The aims of this study were (1) to train an innovative model using artificial intelligence (AI)–based methods on two-dimensional facial frontal, lateral, and external ear photographs to assist diagnosis for syndromic craniosynostoses vs controls, and (2) to screen for genotype/phenotype correlations in AS, CS, and PS. We included retrospectively and prospectively, from 1979 to 2023, all frontal and lateral pictures of patients genetically diagnosed with AS, CS, MS, PS and SCS syndromes. After a deep learning–based preprocessing, we extracted geometric and textural features and used XGboost (eXtreme Gradient Boosting) to classify patients. The model was tested on an independent international validation set of genetically confirmed patients and non-syndromic controls. Between 1979 and 2023, we included 2228 frontal and lateral facial photographs corresponding to 541 patients. In all, 70.2% [0.593–0.797] (p < 0.001) of patients in the validation set were correctly diagnosed. Genotypes linked to a splice donor site of FGFR2 in Crouzon-Pfeiffer syndrome (CPS) caused a milder phenotype in CPS. Here we report a new method for the automatic detection of syndromic craniosynostoses using AI.

The orbital cavity is a subject of interest for various specialists, and achieving optimal outcomes requires comprehensive, multidisciplinary management. This study aims to report 10 years of experience in the preoperative, surgical, and postoperative care of patients with orbital lesions, examining their clinical, radiological, and anatomopathological features and outcomes.
A retrospective review of 125 patients who underwent surgical treatment for intraorbital masses between January 2012 and December 2021 was performed. Outcome measures included postoperative diplopia, exophthalmos, decimal visual acuity, eyeball position, ocular motility, operative time, complications, and aesthetic results. A total of 107 patients were included. All cases were discussed with a neuroradiologist to determine the best therapeutic approach based on preoperative imaging.
Preoperative diplopia was linked to extraconal (p = 0.03) and anterior (p = 0.001) lesions, and exophthalmos and visual acuity deterioration were associated with intraconal (p = 0.02; p = 0.03) and retrobulbar (p = 0.001; p = 0.02) lesions. Complications (11.2%) included diplopia, worsened visual acuity, postoperative blepharoptosis, and postoperative ectropion. Of the patients, 80.4% reported an "excellent" aesthetic outcome.
This study underscores the importance of a multidisciplinary approach based on a thorough analysis of preoperative imaging. Periorbital approaches tailored to the lesion's three-dimensional location enables safe access to most intraorbital lesions, resulting in minimal complications and good aesthetic results.
