Use of Submental Intubation in the Full-Face Makeover (Orthognathic Surgery, Facial Prosthesis Combined With Rhinoplasty).

BACKGROUND: Submental intubation is an intubation technique used for the management of airways in patients who suffered from complex maxillofacial trauma. Few studies focused on the role of submental intubation during Full-Face Makeover, like orthognathic surgery, facial prothesis, and rhinoplasty. METHODS: Authors describe a case series of 5 patients who underwent to Full-Face Makeover with submental intubation to manage the airways. The authors started with the Le Fort I subspinal osteotomy. The maxillary repositioning was guided through a 3D printed intermediate splint in all cases (previously simulated with Dolphin software).Subsequentially, the bilateral sagittal split osteotomy was performed. The mandibular repositioning was guided through a 3D printed final splint. The genioplasty was performed with a horizontal osteotomy after a labial mucosa incision. After the genioplasty, the authors used the incision previously used for the Le Fort I osteotomy to bluntly dissect the tissues in order to insert a custom-made polyether ether ketone zygomatic prosthesis. Lastly, an open rhinoplasty was performed. RESULTS: All the surgery lasted a mean less 6 hours. The submental intubation was removed in the operating room, at the end of the surgery. The patients were then discharged from the hospital 2 days after the surgery in all cases. CONCLUSIONS: Submental intubation is a valid method for the airway management in maxillofacial trauma and can be extended in case of Full-Face Makeover like orthognathic surgery combined with rhinoplasty. The absence of nasal traumatism during surgery leads to a more accurate rhinoplasty, with a greater satisfaction for the patient.

The Caudal Septum Pivot Technique for Short Nose Correction.

The short nose represents one of the greatest challenges in rhinoplasty. It is characterized by a reduced distance from the nasal radix to the tip-defining points, often associated with inadequate tip projection. Several techniques have been described for correction of short nose with the common objective of replacing and rebuilding the osteocartilaginous framework. One of the most effective method to correct the short nose is the septal extension graft. The authors describe the caudal septum pivot (CSP) technique, a simple method to elongate short noses by using a graft inserted in the dorsal septum after its division using as pivot the caudal portion, without detaching it from its natural anchorage to the anterior nasal spine. A retrospective analysis was performed reviewing the clinical charts and the operative records of 315 patients who underwent revision rhinoplasty from January 2015 to June 2019; among this group, 34 were considered eligible for the study. The patients (8 men, 26 women; mean age: 25.4 years; age range: 22-53 years) were divided into two groups: in 12 patients (Group 1) the CSP technique was performed, while Group 2 was composed of 22 patients who received a more classic treatment with a septal extension graft. To evaluate the outcomes, nasal length, tip projection, and tip rotation were measured pre- and 1 year postoperatively on digital photographs of each patient. Nasal anthropometric measurements revealed, at 12-month visit follow-up, an improvement in nasal length, tip projection, and nasolabial angle was achieved in all the patients. The comparison of the pre- and postoperative values showed a statistically significant reduction in the nasolabial angle (p < 0.05) and an increase in the tip projection (p < 0.05) and in the nasal lengthening (p < 0.05) in both groups. In authors' experience, the CSP technique could be considered a safe, reliable, and effective alternative technique in selected patients.

Captain America's Shield Genioplasty.

ABSTRACT: The chin represents one of the most important determinants of the facial aesthetics. Like many aesthetic parameters, the "ideal" chin has changed in history regarding projection and prominence. From the retrusive profiles of the Renaissance, stronger and more defined mandibular contour are nowadays desired both by masculine and feminine population.This change in the ideal references plays an important role in diagnosis and treatment planning. Various techniques for chin augmentation have been described, using both alloplastic materials and osteotomies.An interesting osteotomy variant, so-called chin shield osteotomy, has been described by Triaca et al to avoid a deep mentolabial fold. The authors describe herein the use of a shield plate, very similar in his form to Captain America's shield, that can at the same time provide bone fixation and soft tissues sustain in the mentolabial fold region, preventing the invasion of the gap between the bone fragments by the connective tissue, as it happens in a guided bone regeneration procedure.

The Pyramid Chin Augmentation: A New Technique.

ABSTRACT: The surgical approach to chin for esthetical purpose can be isolated or in a combination with other treatments like maxillomandibular surgery. Both possibilities include sliding genioplasty or implants of autologous or alloplastic materials. In this article, the authors present their new technique, the Pyramid Chin Augmentation.In January 2020, a 40-year-old male patient came to authors' observation asking for a great augmentation in the sagittal dimension of the chin, a better pronunciation of mandibular angles and of his cheekbones. The surgical treatment consisted in three different procedures at the same time: a chin wing osteotomy, a Pyramid Chin Augmentation and zygomatic PEEK custom-made malar implants. The pyramid was created on the body of the chin wing with a cortical bone graft from the oblique line of the ascending ramus of the mandible. The harvested bone was cut into strips of rectangular shape gradually shorter to be superimposed on the wing forming a pyramid. A fixation with 2 screws was performed and then was necessary to smoothen the edges of the bone layers.The result immediately after the end of the surgery was in line with the set goals. The mandibular angles were more prominent, the chin was more sagittal pronounced, and there was no evidence of depression in the symphysial region.The Pyramid Chin Augmentation Technique can be a valid tool in chin augmentation surgery and can also represent an effective procedure in the finishing touch of other facial surgery techniques.

The Deviated Nasal Tip: A Personal Technique for Correction Using Monolateral Crural Overlay and Monolateral Dome Truncation.

This study aimed to present a novel approach to correct nasal tip deviation with monolateral crural overlay or monolateral dome truncation, presenting as an isolated deformity or in complex nose deviations. Nasal tip deviation can be congenital or posttraumatic, due to a dislocated septum or cartilaginous septal or lower lateral cartilage malformations. Although some treatment strategies have been introduced, appropriate treatment remains a challenge because of the complexity and variability of such deformities. It had been assumed that in most nasal tip deviations, a lower lateral cartilage was longer than the contralateral one. The authors analyzed 158 patients from January 2015 to October 2019 with nasal tip deviation and corrected the deviated tip by using a monolateral interruptive technique (lateral crural overlay or monolateral dome truncation) on the lower lateral cartilage. Photographic comparison between preoperative and at least 1-year follow-up for nasal axis deviation variable was analyzed and a self-assessment questionnaire was administrated to the patients at 1-year follow-up. The mean nasal deviation was 6.59° (±3.1°) preoperatively and 1.56° (±0.26°) postoperatively (p < 0.05). The range of differences between pre and postoperative deviations was 2.7° to 15.1°, and the mean difference was 6.1° (±3.21°). Of the 84 patients, 47 (55.95%) were very satisfied, 33 (39.28%) were satisfied, and 4 (4.76%) were unsatisfied with surgical the results and required revision surgery. In authors' hands, monolateral interruptive techniques (lateral crural overlay or monolateral dome truncation) are a viable and feasible option to restore nasal tip symmetry. These techniques achieved high satisfaction rates among patients and resulted in reliable and reproducible symmetry immediately visible after surgery and stable over time (1-year postsurgery controls).

How to Produce Cheap and Easy Custom-Made Sterilizable Filtering Facepiece 2/3 Masks for Healthcare Providers During Pandemic COVID-19 Emergency.

On January 8, 2020, a novel coronavirus was officially announced as the causative pathogen of coronavirus disease (COVID-19) by the Chinese Center for Disease Control and Prevention.On February 26, COVID-19 has been recognized in 34 countries, with a total of 80,239 laboratory-confirmed patients and 2700 deaths.Protecting healthcare workers from infectious hazards is paramount to ensuring their safety in delivering health care.In addition, being able to protect healthcare workers, constituting the front-line response against high-threat respiratory pathogens, such as severe acute respiratory syndrome coronavirus 2, is important for reducing secondary transmission in healthcare-associated outbreaks.Authors present a simple, reliable, and cheap protocol to produce a custom-made sterilizable filtering facepiece 2/3 masks for healthcare providers during pandemic COVID-19 emergency.

Crushed Cartilage: A Rescue Procedure in Rhinoplasty.

While the use of crushed cartilage is now universally recognized as a valid procedure in rhinoplasty to mask irregularities and eliminate slight deficits, there is still no consensus as to the optimal degree of crushing and the rate of graft resorption over time. With a view to casting light on these 2 important aspects and providing some guidelines, the authors present a study of 123 patients subjected to grafts of cartilage with different degrees of crushing in the different areas of the nasal pyramid: upper third (45 patients), middle third (40), and lower third (38). The degree of crushing was medium for 95 patients and high for 28 who presented thinner and less elastic skin. Comparison of the performance over time of the cartilage grafts inserted in the same areas but with different degrees of crushing provides important indications as regard the best way of preparing the material. The results proved satisfactory with improvements for all of the 95 patients subjected to grafts of moderately crushed cartilage. The initial defect was instead still present, albeit with some partial improvement, at a distance of 12 months in 17 of the 28 patients where highly crushed cartilage was used. The study suggests that a moderate degree of crushing offers better results as regard flexibility and stability over time.

Correlation between cranial base morphology and the position of the glenoid fossa in patients with facial asymmetry.

The purpose of this study was to relate the facial asymmetries with possible impairments of the skull base, particularly with regard to the three-dimensional position of the glenoid fossa. Fifty-eight subjects met the inclusion criteria (25 men and 33 women) and were included in the analysis. All patients underwent three-dimensional computed tomographies. Patients were classified into 3 asymmetry groups: vertical plane asymmetries, transversal plane asymmetries (TAs), and hybrid forms. A control group, composed of 29 subjects having obstructive sleep apnea syndrome with no asymmetries, was used to compare data from the study populations. The glenoid fossa moved forward and superiorly on the affected side if compared with the healthy side both in the vertical plane asymmetry group and in the TA groups (P < 0.001). Differences were wider in the TA group. Statistically significant differences regarding the middle and posterior cranial base angles were observed between the affected side of the TA patients and the control group. We reported an amplitude reduction of the middle cranial base angle and an increase of the posterior cranial base angle in the affected side. The glenoid fossa could represent the missing link between the development of the temporal region and the ipsilateral hemimandible.

Vertical distraction osteogenesis combined with bilateral 2-step osteotomy for preprosthetic rehabilitation of edentulous mandible.

The aim of the current study was to appraise the effectiveness of distraction osteogenesis combined with bilateral 2-step osteotomy for the vertical augmentation of atrophic edentulous mandibles. To verify the predictability of this technique, we evaluated bone density and vertical bone gain of a cohort of 27 patients. The intraoral alveolar distractor was placed in the symphyseal area; then, it was left in situ for 2 months after surgery to consolidate the newly formed bone. A total of 189 implants were inserted. The main complications' issue was tied up to the neurosensory disturbances of the inferior alveolar nerve, which disappeared few months after the surgery.At the end of the distraction osteogenesis, a mean vertical bone gain of 10.5 mm evaluated by comparing preoperative and postoperative computed tomography was reached. Three months after the surgery, the radiologic data indicated that the difference in the mean bone density, recorded in Hounsfield units (HU), between the distracted bone and the preexisting mandibular bone was not statistically significant (P > 0.05). The last measurements done showed that the osseous density in the distraction chamber was higher than the original medullary bone density: the regenerated bones were more dense (876.8 [205.9] HU) than the preexisting medullary bone (312.1 [142.3] HU) and less dense than the preexisting cortical bone (1721.1 [170.4] HU) at the ninth month.In conclusion, this approach appeared to be a viable solution for the improvement of vertical volume in atrophic mandibles.

Subtotal septal reconstruction by using conchal graft.

Loss of the cartilaginous nasal septum, a condition frequently encountered in the practice of nasal surgery, can vary in scale depending on its etiopathogenesis. Previous surgery, trauma, and infection can lead to subtotal absence of the septum with severe functional and aesthetic problems. Use of the auricular concha for reconstructive purposes proves an immediate and effective method making it possible to replace the missing tissue without involving operations of a more invasive nature. The fundamental problem in the use of the auricular concha is making this type of cartilage as similar as possible to the cartilaginous septum, endowing it with the structural strength and straightness required for support and the respiratory function. Surgical procedures with the use of figure-eight sutures and grafts of cartilage harvested from the concha prove capable of performing this major task of morphofunctional transformation. The article describes the phases involved in achieving the set objectives.

Evaluation of the dentoskeletal characteristics of an Egyptian mummy with three-dimensional computer analysis.

BACKGROUND: Since the introduction of Roentgen rays in medical diagnostics, mummies have been subjected to radiographic and cephalometric studies. These have, among others, the advantage of providing details that are not directly visible for inspection without the need to tamper with the relics. The acquisition of three-dimensional imaging techniques has also extended the possibility of noninvasive investigation, so that many famous mummies, such as those of Tutankhamun and Ramses II, underwent three-dimensional computed tomography (CT). METHODS: Computed tomography scan of Egyptian mummy of a 20- to 30-year-old woman found in Fayum and dating from the second century B.C. has been performed. DICOM data of the CT scan have been processed by means of a software for three-dimensional CT imaging processing. The purpose of this report was to present the somatic and skeletal characteristics of the mummy. RESULTS: Thanks to the image processing, a "virtual reconstruction" of the original facial features of the mummy has been obtained, and a reliable cephalometric tracing could be performed. The data derived from cephalometric tracings were similar to those published on other studies on a group of Egyptian mummies and on a sample of Iowa adult males. CONCLUSIONS: In our opinion, three-dimensional image processing of CT scan is useful to perform noninvasive morphologic investigations on archeological find, to allow virtual correction of postmortem artifact and to perform reliable cephalometric tracings.

Three-dimensional analysis and treatment planning of hemimandibular hyperplasia.

INTRODUCTION: The advent of computed tomography (CT) provided a useful instrument for diagnosis and surgical treatment of patients with craniofacial malformations. The development of software for three-dimensional graphic simulation applied to CT scan has made possible the three-dimensional computerized analysis, surgical planning, and simulation. This kind of analysis is particularly useful in case of complex facial malformations, making reliable a surgical treatment in 1 step. The purpose of this report was to present the diagnosis and treatment planning on a patient with hemimandibular hyperplasia by three-dimensional cephalometric analysis. METHODS: A 20-year-old young woman who presented with hemimandibular hyperplasia was investigated with CT scan and plaster cast mounted on an articulator; a two-dimensional manual and computerized cephalometric analysis was also developed on frontal and lateral cephalograms. Images in DICOM format were processed on a PC by means of commercial software, thus obtaining the three-dimensional reconstruction of the skeletal structures. RESULTS: Three-dimensional CT permits to program skeletal corrections and to foresee surgical outcomes with adequate realism. Surgical planning based on three-dimensional CT makes it easy and reliable to achieve the correction of the malformation in a single surgical intervention. CONCLUSIONS: The virtual three-dimensional CT model, a versatile diagnostic aid, has proven to be effective in the exact reproduction of bone and soft tissue anatomy, thus helping in the diagnosis, surgical planning, and simulations. Three-dimensional analysis is particularly indicated in case of complex asymmetric malformations, in which the more accurate reproduction of the individual anatomy can be very useful in implementing surgical results.

Pisa Tower Concept: A New Paradigm in Crooked Nose Treatment.

BACKGROUND: The primary element of a crooked nose is a midline deviation of the nasal pyramid. To date, no surgical strategies have been described as compatible with the philosophy of dorsal preservation. The dorsal preservation technique differs from the Joseph structured rhinoplasty because it preserves both the keystone area and the continuity of the cartilaginous vault. The authors focused on the versatility of the dorsal preservation technique even for the deviated nose, introducing the "Pisa Tower concept." METHODS: From January of 2015 to June of 2019, 280 patients diagnosed as having a crooked nose underwent primary septorhinoplasty with dorsal preservation through an asymmetric bony wedge resection and lowering of the bony pyramid onto the frontal process of the maxilla (the let-down osteotomy), in accordance with the Pisa Tower concept. Inclusion criteria were a preoperative computed tomography examination, nasal axis deviation, a complete photographic examination preoperatively, and at least a 1-year follow-up. RESULTS: The mean nasal axis deviation was 7.62 degrees preoperatively and 1.15 degrees postoperatively (p < 0.05). Of the 84 patients, 47 (55.95 percent) were very satisfied, 33 (39.28 percent) were satisfied, and four (4.76 percent) were unsatisfied with surgical results and required revision surgery. CONCLUSIONS: The authors' opinion is that the association of "swinging door" septoplasty with the Pisa Tower concept can be a valid alterative to other techniques when working with the structured rhinoplasty philosophy in patients with a crooked nose. Although this is only a preliminary study, the decreased use of spreaders graft and less aggressive reconstructive methods look very promising. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Perichondrium graft: harvesting and indications in nasal surgery.

Irregularities in the nasal contour of patients who underwent multiple surgeries are frequently related also by skilled surgeons. The aim of this study was to describe the method of harvesting and the primary applications of erichondrium grafts in revision rhinoplasty to prevent postoperative irregularities.Conchal grafts were used in the reconstruction of structures missing as a result of rhinoplasty. The perichondrium was removed from the cartilage during harvesting and fixed on the cartilagenous grafts to fill up empty spaces and make uniform the surface of the grafts. These techniques were used on 62 patients.All of the patients treated showed aesthetic improvement with respect to the preoperative situation. Comparison with other cases in which the perichondrium graft was not used demonstrates its effectiveness in avoiding certain sequelae over time, especially as regards the presence of unattractive sharp edges often visible beneath the cutaneous covering after the use of structural grafts.In conclusion, perichondrium grafting during secondary rhinoplasty is an easily performed technique that involves a small increase in operating time if combined with the harvesting of conchal material. Its application over the surface of cartilage grafts constitutes a stable covering over time that protects the definitive result from irregularities caused by the disappearance of postoperative edema and scar retraction.

Autofluorescence and early detection of mucosal lesions in patients at risk for oral cancer.

Loss of autofluorescence as an early phenomenon associated with tissue degeneration seems to be promising for the diagnosis of oral cancer. The method seems to make visible early structural and biochemical alterations of the oral mucosa not always evident under direct inspection of the oral cavity. For this reason, the margins of the mucosal lesions usually appear wider compared with direct visualization. Actual extension of the potentially malignant lesions must be precisely perceived to avoid any underestimation of the tumor. In this study, 32 patients at risk for oral cancer underwent autofluorescence test. Of these patients, 12 (group A) experienced potentially malignant diseases. The other 20 patients (group B) were previously operated on for oral cancer. In addition, 13 patients showed loss of autofluorescence (8 patients from group A and 5 patients from group B). Among these 13 patients, 12 were affected with lesions of relevance (in group A, 6 had squamocellular carcinoma and 2 had low-grade dysplasia; in group B, 2 patients had high-grade dysplasia, 2 had low-grade dysplasia, and 1 had an epithelial hypertrophy with inflammatory cells). Preliminary results seem to indicate that autofluorescence is a high-performing test for the individuation of oral cancer in populations at risk (sensibility up to 100% and specificity up to 93% in this study).

Early secondary alveoloplasty in cleft lip and palate.

The aims of this study were to present a personal surgical technique throughout the review of international literature concerning surgical techniques, objectives, and outcomes in early secondary alveoloplasty and to describe our personal surgical techniques in alveolar bone defect repair in cleft lip and palate.Throughout a literature analysis, it is now settled that early secondary alveoloplasty could reestablish the continuity of alveolar bone and prevent upper dental arch collapse after presurgical orthopedic upper maxilla expansion; it also might give a good bone support for teeth facing the cleft and allow the eruption of permanent elements with the bone graft and rebalance the symmetry of dental arch, improve facial aesthetic, guarantee an adequate amount of bone tissue for a further prosthetic reconstruction with implant, and finally close the eventual oronasal fistula.The surgical technique we are presenting permitted a total number of 35 early secondary alveoloplasty on which a long-term follow-up is still taking place.We can assess that early secondary alveoloplasty must be performed before permanent canine eruption. Iliac crest is the suggested donor site for bone grafting; orthopedic and orthodontic treatments must be performed in association with surgery, and if there is the dental element agenesia, an implantation treatment must be considered.

Anterolateral thigh flap for the reconstruction of head and neck defects: alternative or replacement of the radial forearm flap?

This paper presents our clinical experience with head and neck reconstruction using radial forearm flap and our preliminary experience with anterolateral thigh (ALT) flap. We analyze the advantages and disadvantages of these 2 flaps from the complications we have encountered. From 1993 to 2006, the radial forearm flap has been used in 75 patients, whereas we began using the ALT flap in 2006. Since this time, we have used the ALT flap in 10 patients. One flap partial loss was observed in a patient who underwent reconstruction of the ethmoid region and nasal bones with an osteofasciocutaneous radial flap. In one patient who underwent reconstruction with ALT flap, inadequate venous outflow was discovered, and the flap was salvaged with reexploration, removing of the cutaneous component of the flap and using antithrombotic agents. Donor-site complications were experienced in 8 of 75 patients who underwent reconstruction with radial forearm flap, whereas all donor thighs healed uneventfully. Anterolateral thigh flap gives optimal results either at the donor site or at the accepting site, being easy to harvest and providing an ideal reconstructive option. Nevertheless, radial forearm flap remains a valuable alternative in case of a thin soft tissue reconstruction because of its thinness and versatility; furthermore, it can provide a long and constant pedicle of large caliber. However, since we began using the ALT flap, we had only performed this flap with respect to radial forearm flap because of its lower donor-site morbidity.

Reshaping of the Anterior Nasal Spine: An Important Step in Rhinoplasty.

The importance of analysis of the nasal spine should not be underestimated in the correct planning of rhinoplasty. Deformations in position with respect to the midline and/or in size are often present, and their correction to ensure harmony between the spine and the other components of the nasal pyramid constitutes a key step in rhinoplasty that can lead to excellent results. METHODS: The study includes 160 patients who underwent surgical treatment of the anterior nasal spine with or without other techniques of nasal reshaping. Eighty-seven of these patients presented with hyperplasia of the nasal spine, 43 with hypoplasia, and 30 with deviation. A combination of deviation and hyperplasia was present in 15 cases. RESULTS: No patients developed postoperative complications. Five patients who underwent anterior nasal spine reduction reported postoperative numbness in the premaxillary area, but sensitivity was fully regained within 4 months after surgery in these patients. All the patients reported postoperative improvement of nasal airflow. A total of 142 patients considered their postoperative aesthetic result as excellent and 18 as good. CONCLUSION: The simplicity of the surgical procedures performed on the nasal spine and the marked aesthetic improvements thus achieved suggest that greater attention should be paid to this anatomical region.

Barrel roll technique for the correction of long and concave lateral crura.

OBJECTIVE: To describe the barrel roll technique that is capable of concurrently correcting 2 associated deformities--overprojection and ptosis of the nasal tip. METHODS: Thirty-two patients with concavity of the upper section of 1 or both lateral crura combined with a droopy tip were treated from January 1, 2005, through December 31, 2007. In all cases, the barrel roll technique was used, which involves rotating the lateral crus by 180° on its major axis so that the concavity is transformed into convexity, and carrying out lateral crural overlay to correct the overprojection concurrently. RESULTS: All the patients displayed functional and aesthetic improvement by correcting the droopy tip and concavity of the lateral crura. Revision was necessary in 1 case of monolateral concavity. The comparison of preoperative and postoperative rhinomanometric data showed significant improvement of nasal airway resistance. CONCLUSIONS: A combination of the overlay technique and rotation of a portion of the lateral crus on its axis is capable of concurrently correcting serious functional problems and aesthetic defects of the nasal tip. The open approach is essential for perfect positioning of the mobilized cartilaginous segments and ensuring stable results over time.

Reconstruction of craniofacial bony defects using autogenous bone grafts: a retrospective study on 233 patients.

For the reconstruction of extensive craniofacial bony defects, autogenous bone is the material of choice because of its potential for revascularization and its osteoconductive and osteoinductive properties. In the present study, the results obtained after grafting with autogenous bone grafts in 233 patients with facial bony defects are analyzed retrospectively. At the Department of Maxillo-Facial Surgery of the University of Rome "La Sapienza," 233 patients (127 males and 106 females) with defects in the craniofacial regions have been reconstructed using autogenous bone grafts between 1997 and 2003. Bone grafts have been obtained from calvaria (N = 29), rib (N = 35), and iliac crest (N = 169). Fixation methods were wire fixation in 72 patients treated between 1977 and 1991 and rigid internal fixation in the 161 patients treated between 1992 and 2003. In 215 cases (92%), an adequate integration of the graft at the recipient site was observed. Complications such as infection and graft resorption requiring graft removal were experienced in seven of 72 patients in which bone grafts have been fixed with wire fixation (9.7%) and in 11 of the 161 patients in which bone grafts have been fixed with rigid internal fixation (6.4%). Even today, revascularized free flaps are the first choice in case of extensive bony defects; in selected cases, bone grafts continue to represent a valid therapeutic option.
