RESUMEN

The chin plays a crucial role as a fundamental structural component that contributes to the overall aesthetics and harmony of the face. Recognizing its central position, medical science has seen the evolution of numerous surgical techniques over the years, all aimed at correcting the range of structural irregularities that can affect the chin. In this contribution, the authors introduce an innovative osteotomy technique, aimed at cases of chin asymmetry in which the skeletal median diverges from the dental median. This technique, called "Tetris genioplasty", involves performing the classic rectangular osteotomy, but includes an additional vertical osteotomy in order to obtain two distinct segments. Finally, these segments are translocated and repositioned to obtain a realignment between the skeletal median and the dental median. The results were entirely satisfactory for the patients, aligning perfectly with the expected appearance after the operation. Furthermore, no complications were reported, proving the success and safety of the procedure. The Tetris genioplasty aligns itself with this progressive trend by offering a minimally invasive method that nevertheless is able to achieve excellent results with a high impact on the patient's quality of life, presenting a promising path in the pursuit of optimal aesthetic results with minimized patient morbidity and greater overall safety.

RESUMEN

INTRODUCTION: Defects in the lower border of the mandible may represent an aesthetic problem after mandibular advancement in orthognathic surgery. The use of bone grafts has been reported in the literature as a possibility to reduce these defects in the postoperative period. OBJECTIVE: The objective of this systematic review is to answer the following research question: Is it necessary to use bone grafts to prevent defects at the lower border of the mandible after mandibular advancement? METHODS: The literature search was conducted on MEDLINE via PubMed, Scopus, Central Cochrane, Embase, LILACS, and Sigle via Open Gray up until December 2020. Five studies were eligible for this systematic review, considering the previously established inclusion and exclusion criteria. RESULTS: 1340 mandibular osteotomies were evaluated, with a mean advance of 8 mm, being 510 with bone graft (42 defects), 528 without graft (329 defects), and 302 with an alternative technique (32 defects). Regarding the type of bone graft used, three articles used xenogenous or biomaterial grafts and two allogenous bone grafts. The results of the meta-analysis showed a reduction in the presence of defects in the bone graft group: OR 0.04, 95% CI = 0.01, 0.19; p = 0.0005, (I2 = 87%; p < 0.0001). CONCLUSION: The use of bone grafts seems promising in reducing defects in the lower border of the mandible after mandibular advancement. New controlled prospective studies with a larger number of participants are needed to ensure the effectiveness of this procedure.

RESUMEN

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.

RESUMEN

OBJECTIVES: The mounting of the plaster casts on articulator procedure is routinely performed in orthognathic surgery to assess canting of the maxillary occlusal plane, but the currently used protocols and reference plane could be source of errors which affect reliability. Nowadays the assessment of canting of the maxillary occlusal plane could be also performed with an entirely digital protocol. Aim of the study was to propose a method to evaluate canting in patients affected by Unilateral Condylar Hyperplasia, comparing the measurements performed on digital models matched on CBCT with those made on traditional articulator. MATERIALS AND METHODS: A retrospective cross-sectional study was designed on 20 patients affected by vertical Unilateral Condylar Hyperplasia treated in the Units of Orthodontics and Maxillo-Facial Surgery. The canting of the maxillary occlusal plane was measured on plaster casts mounted on the conventional articulator and the measures were compared with those made on digital models matched on CBCT, according the protocol developed in our Unit. Molar, canine and basal difference were measured. To compare the two protocols and to test the agreement, we performed descriptive statistics, comparison between means and Bland Altman analysis. P value was set at 0.05. RESULTS: Statistic comparison demonstrated agreement between measurements performed with the digital protocol and conventional physical method. CONCLUSION: Measurements of canting with digital protocol are comparable to the physical standard method. A total digital protocol allows faster availability and storage of patient's data and better communication between orthodontist and maxillo-facial surgeon, especially in patients affected by three-dimensional malocclusions.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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).

RESUMEN

Unilateral condylar hyperplasia (UCH) is a condyle disorder that arises due to osteoblastic hyperactivity, resulting in facial asymmetry, malocclusion and dysfunction. Authors, in this retrospective study, compared "gold standard" manual-segmentation with a "semi-manual one" using 2 kinds of open-source software (Horos and ITK-SNAP; Penn Image Computing and Science Laboratory) to calculate volume of 80 UCH condyles (40 patients). Moreover, volumetric differences between affected condyle and unaffected 1, between males and females, ages, and classification type were also analyzed. Fifteen patients (37.5%) were male and 25 (62.5%) were female. The gender ratio was 5:2, not far from the ratio 2:1 shown in literature. The mean age was 24 (SD 8.6) years; 22.9 (SD 6.6) for males and 24.6 (SD 9.6) for females according with the mean age derived from the Raijmakers et al meta-analysis and the Nitzan et al study. Right side (60%, 24 patients) was more often affected than the left side (40%, 16 patients). The 67.5% (27 patients) were classified as trasversal type, 25% (10 patients) as vertical types and 7.5% (3 patients) as combined. Despite Horos and ITK-SNAP values presenting some differences, the data follows the same tendency. The relationship is stronger for healthy condyles than affected condyles.

RESUMEN

Non-synostotic plagiocephaly consists in an asymmetry of the skull due to mechanical forces applied in utero or postnatally: main differential diagnosis is with true synostotic asymmetry, which is caused by the premature closure of a suture. The correction of positional forms is mostly conservative, with 3 main strategies: counterpositioning, physiotherapy and helmet therapy. There is no synthesized evidence on which is the most effective. The Authors evaluate the modification of antropometric measurments before and after a pediatric physical therapy program in a sample of patients with non-synostotic skull asymmetry, in order to evaluate the improvements in the skull shape. The hypothesis being tested was that physical therapy alone could improve the antropometric measurments. The authors enrolled in this study 24 patients diagnosed of non-synostotic asymmetry, clinically and with ultrasound, referred to the Maxillo-facial Unit of Policlinico Umberto I, Rome, within 2013 and 2016. A standardized pediatric physical therapy intervention program was designed: it consisted in a combination of excercises and manipulative procedures to reduce positional preference, musculoskeletal disorders and cranial deformity. Infants received 16 sessions of physical therapy, of 40 minutes each, once a week, for four months. The Authors evaluate the variation of four anthropometric measurments, performed before and after the physical therapy program: Argenta scale, Oblique Diameter Difference Index (ODDI), Cranial Proportional Index (CPI) or Cephalic Ratio (CR), Cranial Vault Asymmetry Index (CVAI). Craniometric evaluations were extrapolated by standardized 2D digital photographs of frontal, sagittal and transverse planes, by the same physician to minimize bias. The management of positional cranial deformities is still controversially discussed and especially the effects of physiotherapy and osteopathy have been only marginally researched. Statistical analysis revealed the effectiveness of the protocol: all anthropometric measurements improved with a high rate, major in youngest children (P < 0.5) and in more severe first presentations (P < 0.05 or P < 0.01). The results suggest manipulative approach may improve the outcome in the long term follow up of cranial asymmetries.

RESUMEN

BACKGROUND: The association between the synovial chondromatosis (SC) and the calcium pyrophosphate deposition (pseudogotta) in temporomandibular joint (TMJ) is very rare and has been described just 1 patient in the literature. CLINICAL PRESENTATION: A 64-year-old woman was referred to Dipartimento di Scienze Odontostomatologiche e Maxillo-Facciali, Sapienza Università di Roma after complaining about right temporomandibular pain, limitation in mandibular movements, and tumefaction in the right preauricular region. The patient was hospitalized for the surgery. The microscopic examination of the excised material revealed calcium pyrophosphate dihydrate (CPPD) deposits crystals associated with cartilaginous proliferation. CONCLUSION: The association between the SC and the calcium pyrophosphate deposition (pseudogotta) is a challenging diagnosis among TMJ neoplasms.

RESUMEN

Intra-Articular Temporo-Mandibular Disorders (TMD) are characterized by displacement of the disc that causes the condyles to slip back over the disc thus resulting in TMJ discal damage and erosion of the condyle's bone. The etiology of temporomandibular disorder (TMD) is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. The study involved 46 joints in 27 patients with a diagnosis of Intra-Articular Temporo-Mandibular Disorders (TMD) according to Axis I of Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications and underwent surgery between 2011 and 2014. Patients were divided into three groups. Group 1 were included patients with Disc Displacement (DD) without reduction without limited opening, Group 2 patients with DD without reduction with limited opening. Finally, Group 3 included patients with Degenerative Joint Disease (DJD) TMD. In all cases, diagnosis of Intra-Articular Temporo-Mandibular Disorders (TMD) was confirmed by pre-operative examination (clinical, MRI and/or CT scan). Tissue specimens were obtained from all 50 joints for histopathology. The aim of this study was to analyse histological features of the surgical specimens obtained from patients with Intra-Articular Temporo-Mandibular Disorders who underwent surgery and assess the association with clinical findings and imaging. Preliminary results show in Group 1, fibrocartilage is preserved and regular, there are isolated outbreaks of bone resorption and focal sclerosis. In Groups 2 and 3 fibrocartilages are irregular and thickness varies widely and sclerosis is more pronounced. In early stages of TMD, the disc antero-medial displacement might play a fundamental role in the etiopathogenesis that can became an irreversible joint damage thus leading to a wide spectrum of articular symptoms and signs in TMD (Cohen et al., 2014; Hagandora and Almarza, 2012; Nah, 2012).

RESUMEN

BACKGROUND: HFM patients' reconstruction has always been a challenge for maxillofacial surgeons, and numerous reconstructive techniques have been described. Surgical treatment depends on the patient's age and contemplates Temporomandibular Joint (TMJ) reconstruction in conjunction with orthognathic surgery, usually necessary following completion of growth to maximize the functional and esthetic results. Distraction osteogenesis had gained popularity as valid alternative in growing patients, but the two primary methods to reconstruct the TMJs involve the use of autogenous, using free or microvascular bone grafts, or alloplastic graft, but there is no widely accepted method. METHODS: The increasing use of temporomandibular prosthesis for temporomandibular problems has led us to use them even in HFM. A case of female nongrowing patients with HFM type IIb treated with temporomandibular prosthesis in an all-in-one protocol is presented. RESULTS: Incisal opening, measured with BioPAK system (Bioresearch Inc., Milwaukee, USA), was 21.4 mm in the presurgical period and 32.2 mm after all-in-one procedure, for an increase of 50.5%. Excursive movement to the right side was 2.2 mm in the presurgical period and was 1.5 mm after surgery, for a decrease of 31.8%. Left excursion movement changed from 5 mm to 6.1 mm, for an increase of 22.0%. CONCLUSIONS: The TMJ Concepts patient-fitted TJP in conjunction with orthognathic surgery for TMJ and jaw reconstruction is a valid option for patients with HFM.

RESUMEN

INTRODUCTION: Surgical treatment of maxillary tumours is often highly complex. The three-dimensional anatomy of the mid-face renders both correct intraoperative orientation and adequate oncological safety difficult to obtain. Recently, computer-assisted techniques and intraoperative navigation have been applied to oncological surgery treating head and neck cancer. However, only a few studies have explored whether preoperative virtual resection planning and intraoperative control of resection margins allow assessment of the surgical margins of the tumour. In our present feasibility study, we developed a protocol for preoperative mapping of tumour margins using computed tomography and/or magnetic resonance imaging, virtual planning of the surgical resection, and intraoperative navigation during actual resection of advanced maxillary tumours. MATERIALS AND METHODS: Twenty patients were included in this feasibility study. We prospectively selected ten patients requiring surgery to treat malignant maxillary tumours. A control group of ten patients was retrospectively selected. The simulation protocol featured the following steps: 1. "Contouring" of the tumour: identification of the tumour and the borders thereof on the axial, sagittal, and coronal planes; 2. Definition of the resection margins by positioning "landmarks" at least 1 cm from the tumour edges on the axial, sagittal, and coronal planes; 3. Simulation of osteotomy lines passing through the landmarks, and evaluation of the bony defects to be reconstructed. Tumour margins were controlled by using a pointer to identify mobilised regions and then checking the overlap between the planned resection (shown on the LCD screen of the navigation system) and the real anatomical situation. RESULTS: A total of 127 margins were pathologically assessed in the test group, and 85 were assessed in the control group. Overall, 9% of surgical margins were positive in the test group, and 16% were positive in the control group (p = 0.0047). A significant difference was apparent in terms of deep margin evaluation: in test patients, 87% of margins were clear; this figure was 75% for the control group (p = 0.0038). No significant difference in either mucosal or bone margin clearance was evident. The preoperative planning errors were <5 mm for 91% of all planned resection margins. CONCLUSION: The navigation-guided resection protocol seems to improve tumour-free margin status in patients with advanced maxillary tumours. Further confirmatory trial, enrolling a larger cohort of patients, is needed to strengthen these preliminary results and advantages of this procedure.

RESUMEN

Best treatment for paediatric patients with mandibular condylar fractures is still debated, and many approaches have been proposed. Closed treatment is the most used, but there is evidence showing long-term problems in patients with dislocated fractures. On the other hand, there are concerns on surgical treatment with open reduction internal fixation, particularly on the implanted hardware during growth. The aim of this study is to evaluate the long-term outcomes of paediatric patients treated surgically with external fixation. A total of 21 paediatric patients were treated. Diagnostic procedures included clinical and radiographic examinations. Of those 21 patients, 16 presented monocondylar fractures, 5 bicondylar fractures. They were treated surgically with open reduction and external fixation. Patients showed good recovery in maximal mouth opening, maximal lateral excursion and in vertical height of ramus, and all returned to preinjury occlusion. No patient presented permanent facial nerve palsy, and none referred pain or stiffness in the operated area. Minimal scars were visible. Just 1 patient referred clicking in the operated temporo-mandibular joint. Surgical approach using external fixation could be considered an option for treatment of mandibular condylar fractures in paediatric patient. Vertical height recovery, early mobilization, and good occlusion can be achieved, minimizing the risk of facial asymmetry.
