SMAS flap for extracapsular dissection of parotid gland tumors: is it necessary?

OBJECTIVE: The aim of this retrospective article is to evaluate postoperative outcomes after extracapsular dissection for small benign superficial parotid neoplasms (<3 cm) in patients who received Superficial Musculoaponeurotic System (SMAS) flap and in patients who did not receive it. METHODS: Two groups were created and statistically compared regarding Frey's syndrome and aesthetic satisfaction by data collected through the POI-8 validated questionnaire and through an aesthetic satisfaction scale ranging from 1 to 10. The difference between these two groups was the utilization of SMAS flap. SMAS flap was harvested in one of these two group, meanwhile was not used in the other. RESULTS: The p-value analysis between group 1 and group 2 on these complications, resulted statistically not significant. Also, the aesthetic satisfaction resulted not statistically significant between group 1 and group 2. Gender, localization, and facial palsy resulted statistically correlated with the aesthetic satisfaction (p-value < 0.05). CONCLUSION: In conclusion, there is no statistical difference in the use of SMAS flap for benign parotid neoformations of the superficial lobe, with a diameter of less than 3 cm for which extracapsular dissection is adopted as a surgical technique.

Toward Environmentally sustainable surgery: Waste recycling in general surgery operating room. Preliminary cognitive audit.

BACKGROUND: It is common practice to classify waste from the operating theater as "clinical". The development of sustainable policies could have a significant impact. In the first phase, our study aims to measure general surgery waste and to assess the potential financial and carbon savings of appropriate recycling. Based on this information, we will plan for a second phase in which educational interventions will be put in place to promote waste segregation in surgical environments. METHODS: We conducted a preliminary cognitive audit of the most common general surgery procedures to examine the types and quantity of waste produced. We calculated the economic and environmental impacts of disposing of waste treated as clinical or general, and we measured how much of it could actually be recycled. Then, we attempted a projection of the savings we could expect if recycling policies were implemented. RESULTS: We found that more than 30% of total waste was actually recyclable. Considering a projection based on annual procedures performed in our hospital, we estimated that for each kind of surgical procedure, we could expect a reduction of the carbon footprint by approximately 6%, and an average 3% reduction in costs every year, only by improving waste segregation in the general surgery operating rooms. CONCLUSION: There could be a great potential for reducing environmental and economic footprint of the operating rooms by promoting waste recycling protocols. Surgeons are in a unique position to implement for these protocols. Interventions should be codesigned with theater staff to create a "green culture".

Plasmacytoma in the Maxillary Jaw: A Diagnostic and Therapeutic Challenge.

Plasmacytoma is a neoplastic disorder originating from plasma cells, with bone and soft tissue being common sites of manifestation. This report presents the clinical and radiological findings of a 65-year-old female patient who presented with an exophytic lesion in the upper right lateral incisor region. The lesion appeared as a unilocular radiotransparent area in imaging tests. Following an excisional biopsy, histological and immunohistochemical evaluations confirmed the presence of mature plasmacellular elements and small infiltrates of B and T lymphocytes. The patient did not exhibit systemic manifestations of multiple myeloma. Surgical intervention, in the form of enucleation of the lesion combined with root canal treatment and apicoectomy, was performed. This case underscores the rare occurrence of plasmacytoma in the jaw region and highlights the importance of surgical management in cases where structural damage or functional impairment is present. Further research on novel treatment approaches is also mentioned, including targeted therapies, immunomodulatory agents, and monoclonal antibodies. The patient is currently under the care of a hematologist for further investigation and the choice of the most appropriate therapy.

Low-Level Laser Therapy for the Treatment of Oral Mucositis Induced by Hematopoietic Stem Cell Transplantation: A Systematic Review with Meta-Analysis.

Oral mucositis is a common and debilitating side effect induced by stem cell transplantation that is experienced by cancer patients undergoing chemotherapy or radiation therapy. This condition involves inflammation and ulceration of the oral mucosa, leading to pain, difficulty with eating and speaking, and an increased risk of infections. Mucositis not only compromises the quality of life for cancer patients, but also affects treatment outcomes and may necessitate dose reductions or treatment delays. This scientific article provides a comprehensive overview of mucositis. The purpose of this literature review with a meta-analysis is to evaluate the efficacy of laser therapy in treating post-transplant mucositis. Materials and methods: A search of the literature from 3 May 2023 was carried out on three online databases, PubMed, Scopus, and Web of Science. Only studies that treated patients with laser therapy were considered; only studies with the placebo-treated control group were considered. Review Manager version 5.2.8 (Cochrane Collaboration) was used for the pooled analysis. We measured the std. mean difference between the two groups (laser and placebo). Results: There were 230 papers included in this review. Two hundred twenty-seven were excluded. Furthermore, a manual search was performed. After the search phase, three articles were considered in the study. The overall effect showed differences in the degree of mucositis in the laser-treated patients compared with the placebo group. The meta-analysis shows a reduction in the degree of mucositis in the patients treated with laser therapy (std. mean difference -1.34 [-1.98; -0.98]; C.I. 95%). Conclusions: The application of laser therapy results in decreased severity of oral mucositis from radiation and chemotherapy. Our study shows that the application of low-level laser therapy in the treatment of transplant mucositis has excellent efficacy in relieving the symptoms and severity of mucositis.

Vascular complications with necrotic lesions following filler injections: Literature systematic review.

INTRODUCTION: Although the related risk of vascular necrosis due to filler injection is low, the outcomes can be severe when they occur. This systematic review aims to report the occurrence and treatment of vascular necrosis due to filler injection. MATERIALS AND METHODS: The systematic review was performed according to PRISMA guidelines. RESULTS: The results showed the most used treatment is a combination of pharmacologic therapy and hyaluronidase application, which is efficacy when applied in the first 4 h. In addition, even though management recommendations are available in literature, proper guidelines are unavailable due to the low number of complications occurrence. CONCLUSION: Clinical and high-quality studies on treatment and management of filler injection combination are necessary to provide scientific evidence on what to do in case of vascular complication occurrence.

The socket shield technique and its complications, implant survival rate, and clinical outcomes: a systematic review.

PURPOSE: The aim of this systematic review was to evaluate the effectiveness of the socket shield technique (SST), an innovative surgical method introduced in 2010, for reducing buccal bone plate resorption. METHODS: The review was conducted following the PRISMA guidelines. Clinical studies conducted in humans and investigating the SST were searched on PubMed (MEDLINE), Embase, Web of Knowledge, and Google Scholar in November and December 2021. The implant survival rate, percentage of complications, and clinical parameters (marginal bone loss [MBL], pink esthetic score [PES], and buccal bone plate resorption [BBPR]) were analyzed using the collected data. RESULTS: The initial search resulted in 132 articles. After article screening, the full texts of 19 studies were read and 17 articles were finally included in the review. In total, 656 implants were installed with the SST. Nine of the 656 implants experienced failure, resulting in an implant survival rate of 98.6%. The percentage of complications was about 3.81%. The analysis of clinical parameters (MBL, PES, and BBPR), showed favorable results for the SST. The mean MBL in implants placed with the SST was 0.39±0.28 mm versus 1.00±0.55 mm in those placed without the SST. PES had a better outcome in the SST group, with an average of 12.08±1.18 versus 10.77±0.74. BBPR had more favorable results in implants placed with the SST (0.32±0.10 mm) than in implants placed with the standard technique (1.05±0.18 mm). CONCLUSIONS: The SST could be considered beneficial for preserving the buccal bone plate. However, since only 7 of the included studies were long-term randomized controlled trials comparing the SST with the standard implant placement technique, the conclusions drawn from this systematic review should be interpreted with caution.

Impact of COVID19 on Maxillofacial Fractures in the Province of L'Aquila, Abruzzo, Italy. Review of 296 Patients Treated With Statistical Comparison of the Two-Year Pre-COVID19 and COVID19.

ABSTRACT: The aim of this study was to understand the impact of the COVID-19 pandemic on the epidemiology of maxillofacial trauma in a regional trauma center in L'Aquila, Abruzzo, Italy, during the first wave of the pandemic and comparted it to an equivalent period from 2015 to 2018. The authorshave retrospectively analyzed personal data, site of trauma, etiology, and mechanism of injury. Statistical analysis has been carried out utilizing IBM SPSS Statistics software (IBM Corp., Armonk, NY) and significance was accepted for P values of <0.05. From January 2015 to December 2020, a total of 296 were analyzed. In Pre-COVID era, 195 patients were evaluated, 130 males (66.6%) and 65 females (33.4%). Zygomatic-malar complex fractures were the most common site of trauma in both genders (53%), followed by mandibular fractures (23%) and orbital ones (15%). The highest incidences of injuries were recorded between 15 and 34 years (21%) with the most common etiology attributed to road accidents traumas (49%). In COVID19 era, the authors recorded 101 traumas, 58 males (57.4%), 43 females (42.6%). Zygomatic-malar complex fractures were confirmed as the most common ones in both genders (41%). The most common etiology was related to casual domestic accident and assaults (37% and 30%, respectively). There was no statistically significant difference in terms of incidence in the comparison of Pre-COVID19 and COVID19 periods (P > 0.05) as opposed to the etiology in which the road traffic accidents decreased in favor of domestic accidents and interpersonal assaults (P < 0.05). Our scientific study represents the first epidemiologic study related to the impact of COVID-19 on maxillo-facial trauma in the Province of L'Aquila, Abruzzo, Italy. A decrease in the number of Maxillofacial injuries related to road traffic accidents can be demonstrated as the benefit of lockdown, however, a significant increase in the number of physical assaults shows how isolation and restrictions have had a highly negative psychological impact on society.

Different Solutions for Damaged Nasotracheal Tube during Maxillofacial Surgery: A Case Series.

Difficult airway management and intraoperative tube damage are important problems during maxillofacial surgery. Damage occurs frequently during the surgery, and the anesthesiologist must be ready to find a quick and safe solution. Replacing the damaged endotracheal tube involves additional difficulties, and various factors must be evaluated. We present two cases of nasotracheal tube (NTT) damage suffered during maxillofacial surgery. The different intraoperative conditions led us to decide for the replacement of NTT in one case and for conservative action in the other. The purpose of this article is to highlight the difficulties that the anesthesiologist may have in deciding quickly what is the best approach in case the endotracheal tube is damaged during maxillofacial surgery and possibly try to provide a rapid and safe solution for the situation.

Short Versus Longer Implants in Mandibular Alveolar Ridge Augmented Using Osteogenic Distraction: One-Year Follow-up of a Randomized Split-Mouth Trial.

The aim of this study was to evaluate the reliability of 6-mm-long implants compared with normal-length implants placed in a vertical augmented atrophic posterior mandible, supporting cemented single crowns. Thirty-six patients with bilateral posterior edentulous mandible and presenting a bone availability height less than 9 mm from the mandibular canal were enrolled in this study. Patient hemiarches were randomized to receive both 6-mm-long and normal-length implants (10 mm). The technique used for the vertical bone augmentation was the "sandwich" technique, using a bone substitute block as graft. The data outcomes at 1 year postloading follow-up were the loss of implants and complications. Eighty-six 6-mm-long implants and 84 normal implants were inserted. Five short implants and 13 normal implants were lost. In 28 patients, complications occurred, and in 21 cases, the complication was present on the side of the ridge vertical augmentation. From the statistical analysis, the association between the side of the ridge augmentation and the side of occurrence of the complication was statistically significant ( P < .05). The results from this trial suggest short implants can be preferred over vertical bone augmentation for the placement of longer implants in the rehabilitation of edentulous posterior mandibles. These initial results must be confirmed by larger and longer follow-ups of 5 years or more.

Combined supra-transorbital keyhole approach for treatment of delayed intraorbital encephalocele: A minimally invasive approach for an unusual complication of decompressive craniectomy.

BACKGROUND: Intraorbital encephalocele is a rare entity characterized by the herniation of cerebral tissue inside the orbital cavity through a defect of the orbital roof. In patients who have experienced head trauma, intraorbital encephalocele is usually secondary to orbital roof fracture. CASE DESCRIPTION: We describe here a case of a patient who presented an intraorbital encephalocele 2 years after severe traumatic brain injury, treated by decompressive craniectomy and subsequent autologous cranioplasty, without any evidence of orbital roof fracture. The encephalocele removal and the subsequent orbital roof reconstruction were performed by using a modification of the supraorbital keyhole approach, in which we combine an orbital osteotomy with a supraorbital minicraniotomy to facilitate view and access to both the anterior cranial fossa and orbital compartment and to preserve the already osseointegrated autologous cranioplasty. CONCLUSIONS: The peculiarities of this case are the orbital encephalocele without an orbital roof traumatic fracture, and the combined minimally invasive approach used to fix both the encephalocele and the orbital roof defect. Delayed intraorbital encephalocele is probably a complication related to an unintentional opening of the orbit during decompressive craniectomy through which the brain herniated following the restoration of physiological intracranial pressure gradients after the bone flap repositioning. The reconstruction of the orbital roof was performed by using a combined supra-transorbital minimally invasive approach aiming at achieving adequate surgical exposure while preserving the autologous cranioplasty, already osteointegrated. To the best of our knowledge, this approach has not been previously used to address intraorbital encephalocele.

A new operative open-wings technique to correct the frontoforehead unit in metopic synostosis.

The technology adoption and creation of a multidisciplinary team have helped to overcome the complexity associated. Craniofacial surgery has thus emerged from the valuable contributions of neurosurgery, maxillofacial surgery, plastic surgery, eyes, nose, and throat as well as head and neck surgery. A patient with trigonocephaly may present a prominent "keel" forehead, accompanied by recession of the lateral orbit rims, hypotelorism, and constriction of the anterior frontal fossa when the metopic suture fuses before 6 months of age. In a period between 2007 and 2011, in the Salesi Children's Hospital, were treated for nonsyndromic variety of metopic synostosis 11 infants; their ages ranged from 6 months to 9 months, and 7 were males and 4 females. The most important aims of our new surgical technique are the achievement of symmetry as well as normal proportion and reconstruction of the frontoforehead unit but remaining in a very conservative treatment. The morphology and position of the supraorbital ridge-lateral orbital rim region are key elements of upper facial esthetics. This new "open-wings" technique for the reconfiguration of the bilateral emisupraorbital bar requires a midline incomplete osteotomy that involves only the internal cortex of the frontonasal region. Hence, both lateral orbital walls are bent inwardly and tilting forward, as in computed tomographic scan planning, with a greenstick fracture pivoting on the preserved medial frontonasal region. This open-wings conservative technique allows the avoidance of the most important complication that may result in the traditional way such as dead space in the anterior cranial fossa, infections, and blood loss but with an achievement of satisfactory craniofacial form and aesthetic result.

Piezosurgery as a further technical adjunct in minimally invasive supraorbital keyhole approach and lateral orbitotomy.

OBJECTIVE: One of the problems in neurosurgery is how to perform rapid and effective craniotomies that minimize the risk of injury to underlying eloquent structures. The traditional high-powered pneumatic tools and saws are efficient in terms of speed and penetration, but they can provoke bone necrosis and sometimes damage neurovascular structures. As an alternative, we evaluated the piezoelectric bone scalpel (piezosurgery), a device that potentially allows thinner and more precise bone cutting without lesioning neighboring delicate structures, even in the case of accidental contact. MATERIAL AND METHODS: From January 2009 to December 2011, 20 patients (8 men and 12 women), 19 to 72 years of age (mean: 49.3 years) were treated using piezosurgery. Surgery was performed for the removal of anterior cranial fossa meningiomas, orbital tumors, and sinonasal lesions with intracranial extension. RESULTS: The time required to perform craniotomy using piezosurgery is a few minutes longer than with traditional drills. No damage was observed using the piezoelectric device. Follow-up clinical and neuroradiologic evaluation showed a faster and better ossification of the bone flap with good esthetic results. CONCLUSIONS: Piezosurgery is a new promising technique for selective bone cutting with soft tissue preservation. This instrument seems suitable to perform precise thin osteotomies while limiting damage to the bone itself and to the underlying delicate structures even in the case of unintentional contact. These advantages make the piezoelectric bone scalpel a particularly attractive instrument in neurosurgery.

Clinical management of a patient with advanced mucosal malignant melanoma in the sinonasal area.

We describe a case of mucosal malignant melanoma in the sinonasal area of a 65-year-old woman. She presented with a history of nasal obstruction and epistaxis with subsequent tenderness, facial anesthesia involving cranial nerve V2, red eye, proptosis, diplopia, and conjunctival chemosis. Computed tomography detected a nonspecific solid mass that had involved the left maxillary sinus and surrounding tissues, with extension into the nasal cavity and invasion of the orbital floor and eye muscles. Histopathologic examination of the neoplasm revealed that it was a malignant melanoma. We performed a radical hemimaxillectomy that extended to the orbit, which allowed for radical excision of the tumor. Postoperatively, the patient received adjuvant chemotherapy and radiotherapy. Mucosal melanoma in the head and neck is a rare and highly malignant neoplasm. We suggest that malignant melanoma be suspected when a small-round-cell tumor is found on light microscopy, and we confirm the usefulness of immunohistochemical investigations.

Piezosurgery for osteotomies in orbital surgery: Our experience and review of the literature.

INTRODUCTION: Piezoelectric bone surgery, simply known as Piezosurgery(®), is a new promising technique for bone cutting based on ultrasonic microvibrations that allows to perform precise and thin osteotomies with soft tissue sparing. PRESENTATION OF CASE: A 45-years-old woman presenting with progressive left ocular pain, diplopia on the lateral left gaze, and visible exophthalmos was admitted to our department. CT scan and MRI images documented a left supero-lateral orbital lesion. A left lateral orbitotomy using the piezoelectric scalpel was performed. The tumour (lacrimal gland lymphoma) was completely removed with no injuries to the orbital structures and with a perfect realignment of the bone stumps. DISCUSSION: High powered pneumatic osteotome are commonly used to perform craniotomies. Large bone cutting groove and high temperatures developing at the contact site could produce an uneasy bone healing. The use of a piezoelectric scalpel allows to realize precise and thin osteotomies, facilitating craniotomy's borders ossification and avoiding injuries to non-osseous structures. CONCLUSION: Widely used in Oral and Maxillofacial Surgery, Piezosurgery(®) can also be useful in neurosurgical approaches in order to obtain a faster bone flap re-ossification, a better aesthetic result, and a lower risks of dural layer and soft tissue damage.

Multiple and synchronous peripheral giant cell granulomas of the gums.

The presence of multiple giant cell lesions in the maxillofacial region is suggestive of hyperparathyroidism or neurofibromatosis. A case of synchronous, multiple peripheral giant cell granulomas is reported, bilaterally affecting the mandibular gums and also the upper right maxillary gingival mucosa, without concomitant systemic disease. Only 2 cases of central giant cell granulomas, and no cases of peripheral giant cell granulomas exhibiting similar characteristics, have been reported in the literature to date.
