Background: Orbital exenteration is a radical procedure used in selected orbital malignancies, yet survival outcomes vary widely, particularly in recurrent or previously treated disease. We evaluated the association of pathological stage (nodal and/or distant metastasis status) and margin status with overall survival (OS) and disease-free survival (DFS) in patients undergoing exenteration for recurrent or previously treated orbital cancers. Methods: We retrospectively analyzed 39 patients who underwent orbital exenteration between 2017 and 2024. Patients were categorized as localized disease (pN0/pM0) or advanced disease with nodal and/or distant metastasis (pN + and/or pM+). Survival was estimated using Kaplan–Meier analysis and compared using the log-rank test. Median follow-up was 365 days. Margins were classified as R0 or R1. Results: Of the 39 patients, 24 (61.5%) had localized disease and 15 (38.5%) had advanced disease with nodal and/or distant metastasis; 6 patients (15.4%) had positive margins. 24-month OS was 78% in localized disease versus 33% in patients with nodal and/or distant metastasis ( p = 0.011). Median OS was not reached in localized disease and was 13 months in patients with nodal and/or distant metastasis. 24-month DFS was 62.5% versus 33% ( p = 0.017). R1 margins were associated with markedly worse outcomes: 24-month OS 0% vs. 75.8% for R0, and all R1 patients recurred within 12 months. Sensitivity analysis excluding < 6-month follow-up confirmed these findings. Conclusions: Nodal and/or distant metastatic status and positive surgical margins were associated with worse survival outcomes after orbital exenteration for recurrent or previously treated orbital malignancies. Most adverse events occurred within the first postoperative year, suggesting a clinically relevant early risk period. Given the histological heterogeneity of the cohort, these findings should be interpreted as prognostic patterns in a salvage orbital oncology population and require validation in larger disease-specific series.

Pilomatricomas are benign tumors originating from hair follicle matrix cells and represent the most common skin tumors in pediatric patients. Pilomatricomas may be associated with genetic syndromes such as myotonic dystrophy, familial adenomatous polyposis (FAP), Turner syndrome, Rubinstein–Taybi syndrome, Kabuki syndrome, and Sotos syndrome. This study reviews the literature on pilomatricomas occurring in syndromic contexts and presents a novel case linked to Apert syndrome. A systematic review was conducted using PubMed and Cochrane databases, focusing on case reports, case series, and reviews describing pilomatricomas associated with syndromes. A total of 1272 articles were initially screened; after removing duplicates and excluding articles without syndromic diagnoses or lacking sufficient data, 81 full-text articles were reviewed. Overall, 96 cases of pilomatricomas associated with genetic syndromes were identified. Reports of patients with Apert syndrome who do not develop pilomatricomas are absent in the literature. Pilomatricomas predominantly affect pediatric patients, with a slight female predominance, and are often the first manifestation of underlying genetic syndromes. Our study highlights previously unreported associations of pilomatricoma with Apert syndrome, providing molecular insights. This study contributes to understanding the clinical and molecular features of pilomatricomas in syndromic contexts and underscores the importance of genetic analysis for accurate diagnosis and management.

The zygomaticomaxillary complex is integral to facial aesthetics and is frequently involved in facial fractures. These injuries often necessitate surgical intervention, with open reduction and internal fixation being the standard treatment. This article presents a novel philosophy for managing zygomatic fractures, emphasizing the “Scarless Surgery” technique. The authors' approach prioritizes minimal osteosynthesis material and fixation points while utilizing the least visible surgical access. For isolated zygomatic arch fractures, an intraoral technique is preferred, whereas the frontozygomatic suture is approached through an upper eyelid crease for optimal aesthetic outcomes. The zygomaticomaxillary buttress is accessed through a vestibular mucosal incision and the infraorbital rim benefits from a transconjunctival approach. The findings suggest that fewer fixation points can still yield satisfactory stability and cosmetic results, aligning with literature supporting the efficacy of 1 and 2-point fixations. This modern technique not only minimizes visible scarring but also conforms to the contemporary push for minimally invasive surgical methods. The authors' experience and the existing literature support the efficacy of this approach, reinforcing its viability as a standard practice in the surgical management of facial trauma.

Thanks to the use of new digital technologies and innovations in materials, there has been an increasing interest in subperiosteal implants. These implants are considered to be helpful for the rehabilitation of severe jaw atrophies, as they overcome some disadvantages of endosseous implantology. In the present clinical retrospective study, 18 patients were treated and the clinical outcomes of the treatment were recorded after 12 months of follow-up.

Polyetheretherketone (PEEK) in the last few years has emerged as an exceedingly promising material for craniofacial defects due to its biocompatibility and mechanical properties. However, its utilization remains controversial due to its inertness and low osteoinductivity. This study aimed to investigate the postoperative outcomes of patients undergoing maxillo-facial and neurosurgical procedures with PEEK implants. The focus is on evaluating bone regrowth on the surface and edges of the implant, periosteal reactions, and implant positioning. A retrospective analysis of 12 maxillo-facial surgery patients and 10 neurosurgery patients who received PEEK implants was conducted. CT scans performed at least one year post operation were examined for bone regrowth, periosteal reactions, and implant positioning. In maxillo-facial cases, the analysis included mandibular angle and fronto-orbital reconstruction, while neurosurgical cases involved cranioplasty. In maxillofacial surgery, 11 out of 12 patients showed radiological evidence of bone regrowth around PEEK implants, with favorable outcomes observed in craniofacial reconstruction. In neurosurgery, 9 out of 10 patients exhibited minimal or none bone regrowth, while one case demonstrated notable bone regeneration beneath the PEEK implant interface. The study highlights the importance of implant design and patient-specific factors in achieving successful outcomes, providing valuable insights for future implant-based procedures.

Introduction: The purpose of this study was to assess the overall survival (OS) and disease-free survival (DFS) of patients who underwent orbital exenteration for periorbital, conjunctival, and primary intraorbital carcinomas. Additionally, we assessed the outcomes of anterior retrograde temporalis muscle flap restoration. Methods: For all patients who had orbital exenteration in the previous five years, a non-comparative retrospective assessment of their medical records, histology, and radiographic imaging was carried out. We investigated the relationships between the various qualitative factors using Cramer’s V Kaplan–Meier (KM) analysis. For each of the patient’s categorical factors that were of relevance, estimates of the survival distribution were displayed, and log-rank tests were used to determine whether the survival distributions were equal. Results: This study looks at 19 participants. The sample is made up of 13 men (68%) and 6 women (32%). The degree of relationship (Cramer’s V index) between lymph node metastases (N) and the existence of distant metastases (M) is high, at 64%, and is statistically significant because the p-value is 0.0034 < 0.005. Lymph node metastases had a statistically significant impact on overall survival (p = 0.04 < 0.05). Thirteen of the nineteen patients tested had no palsy (68%). There was no one presenting a CSF leak. Conclusion: Our findings show how crucial it is to identify any lymph node involvement that orbital neoplasms may have. In patients who have received many treatments, sentinel lymph node biopsy (SLNB) may be used to determine the stage and spread of the cancer. To determine whether additional tumor characteristics may be explored, more expertise in the SLNB field for patients with orbital cancer who have received many treatments may be helpful. To prevent additional scarring and to be comparable to previous techniques for facial nerve lesions, the anterior retrograde approach and the transorbital procedure for temporal muscle flap in-setting are both effective methods.

Background: Polyetheretherketone (PEEK) is a synthetic material with many favorable characteristics; PEEK implants are increasingly used for a variety of applications ranging from cranioplasty to orthopedic surgery and facial implants. Methods: This study is a retrospective review of patients who underwent PEEK implant placement in our department over the last 5 years. Polyetheretherketone computer-aided design and manufacture facial implants were designed from high-resolution computed tomography (CT) scans of each patient. The implants placed were onlay implants used for facial rehabilitation purposes to correct malformative and posttraumatic malformations. Results: Twenty-eight consecutive patients (11 males and 17 females) underwent PEEK implant positioning between January 2015 and December 2020. Common indications were anterior plagiocephaly, hemifacial microsomia, and residual facial imbalance after orthognathic surgery. No complications of implant breakdown, exposure, infection, or displacement were noticed during the follow-up period. During routine controls on 3 patients, we requested a craniomaxillofacial CT scan for reasons unrelated to the implanted prostheses. The CT scans were all high resolution (<1-mm slices). The CT images indicated that bone was starting to form around the implant in all 3 patients as well as in the penetrating holes that were planned in the implants. Conclusions: In our experience, computer-designed, patient-specific PEEK onlay implants are a valid option for the treatment of malformative and posttraumatic malformations. This is, to the best of our knowledge, the first clinical report on bone reaction to PEEK implantation in the maxillofacial field. Moreover, based on the signs of bone regrowth that we observed in CT controls we can presume that the design of this type of prosthesis can probably take advantage of some technical stratagems not yet codified and fully exploited. Despite our preliminary favorable results, further multicentric and comparative studies are necessary to evaluate outcomes and better understand the behavior of this promising material and thus optimize its use in craniomaxillofacial surgery.

Background: Three-dimensional renderings of two-dimensional computed tomography data have allowed for more precise analysis in the craniofacial field. Design, engineering, architecture, and other industries have paved the way for the manipulation and printing of three-dimensional objects. The usual planning is only carried out based on the bony structures, often without taking into consideration the presence of soft tissues and soft structures. During our practice, we have found ourselves facing the challenge posed by these structures; the aim of this article is to discuss our experience in designing implants presenting our tips and tricks for a better planning leading to an easy and reliable positioning. Case presentation: We have retrieved all patients in 5 years among those who underwent computer-aided design/computer-aided manufacturing implant placement in the last 5 years in order to review the eventual problems and the solutions found. A total number of 25 patients were retrieved and, among them, 10 patients were selected, in which planning inaccuracy caused difficulties during implant placement and which then led to induced changes during the planning of similar cases or in which the problems were noted before or during the planning which led to changes in the plan to address those problems. Six of the selected cases were polyetheretherketone facial implants for the correction of residual deformities in malformed or deformed patients. One case was a delayed orbital reconstruction with a titanium implant. Two cases were titanium functional and anatomical reconstruction of the mandible in patients with failed post-oncological reconstructions. There was 1 case with a mandibular ramus complex and hard-to-treat fracture. Conclusions: The planning of the implant mostly relies on hard tissue three-dimensional reconstruction, but it should not be limited at what is immediately evident. A surgeon’s clinical experience should always guide the process, with knowledge of the patient’s anatomy and evaluation of the quality and of the soft tissue response being taken into consideration. The implant should always be tailored not only based on the bone defect and evaluations but also using the patient’s previewed and actual anatomy, evaluating eventual interferences and pitfalls.

Italy has been the first affected country in the western hemisphere by SARS-CoV-2 with over 200,000 cases during the first months of the pandemics. To control the spread of the virus, the whole country was placed under lockdown with limitations in the circulation of people and vehicles from March 2020 to the first half of the month of May. We aimed to analyze the incidence and type of facial traumas referred to our tertiary care hospital during the months of Italy lockdown due to SARS-CoV-2 spread compared with those during the same months of 2019 to determine eventual variations in the incidence, type and causes of trauma. During the 2 months of COVID-19-related lockdown, a dramatic decrease in facial trauma patients was observed at our tertiary care hospital with a shift toward older age ranges. Regarding the causes of trauma, the largest percentage reduction was found in road, sports and work accidents; this percentage reduction was not found in aggressions. A small increase in the percentage was also found regarding surgical indications, likely because more severe cases were more prone to be referred to the hospital despite the fear of being infected.
