Abstract
BACKGROUND Current indications of maxillary reconstruction with scapular tip free flap (STFF) are palatoalveolar defects associated with zygomaticomaxillary buttress and/or orbital floor defects. STFF can be placed either horizontally or vertically. Horizontal placement usually allows ideal palatal conformation, preventing oronasal communication, but has been argued to compromise orbital support and projection of the midface, whereas vertical placement is advocated for midface support but may be insufficient for the complete closure of the palate. The present study focuses on the horizontal placing of STFF to allow complete palate reconstruction and fistulae prevention while still obtaining optimal midface projection and orbital support. MATERIALS AND METHODS This study included 21 case complex maxillary reconstructions with this flap, in which the horizontally placed scapular tip component replaced the palate, a muscular flap component was included for midface volume restoration, and an alloplastic implant was utilized for supporting the orbital content when needed. RESULTS None of the patients presented palatal fistulas or alterations in the orbital support. CONCLUSION A multilevel approach was proposed according to the maxillectomy defect. This experience supported the horizontal insetting of STFF to allow palatal fistulae prevention while still obtaining an optimal midface projection and orbital support.

Int J Oral Maxillofac Surg 2024; 53:146-155. [PMID: 37391321 DOI: 10.1016/j.ijom.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 05/23/2023] [Accepted: 06/08/2023] [Indexed: 07/02/2023]
Abstract
Bilateral maxillary defects are a challenge for fibula free flap reconstruction (FFFR) surgery due to limitations in virtual surgical planning (VSP) workflows. While meshes of unilateral defects can be mirrored to virtually reconstruct missing anatomy, Brown class c and d defects lack a contralateral reference and associated anatomical landmarks. This often results in poor placement of osteotomized fibula segments. This study was performed to improve the VSP workflow for FFFR using statistical shape modeling (SSM) - a form of unsupervised machine learning - to virtually reconstruct premorbid anatomy in an automated, reproducible, and patient-specific manner. A training set of 112 computed tomography scans was sourced from an imaging database by stratified random sampling. The craniofacial skeletons were segmented, aligned, and processed via principal component analysis. Reconstruction performance was validated on a set of 45 unseen skulls containing various digitally generated defects (Brown class IIa-d). Validation metrics demonstrated promising accuracy: mean 95th percentile Hausdorff distance of 5.47 ± 2.39 mm, mean volumetric Dice coefficient of 48.8 ± 14.5%, compactness of 7.28 × 105 mm2, specificity of 1.18 mm, and generality of 8.12 × 10-6 mm. SSM-guided VSP will allow surgeons to create patient-centric treatment plans, increasing FFFR accuracy, reducing complications, and improving postoperative outcomes.

Abstract
BACKGROUND Microsurgical bone reconstruction is challenging in cases of anterior maxillary defects because of the presence of residual teeth. The study analyzed the method and feasibility of using vascularized bone flaps to reconstruct anterior maxillary defects. METHODS We retrospectively analyzed 15 patients treated at the Department of Oral and Maxillofacial Surgery, Peking University School, and Hospital of Stomatology between November 2017 and January 2023. RESULTS A total of 14 patients were successfully reconstructed using the digital technique: 6 deep circumflex iliac artery (DCIA) flaps and 8 fibular free flaps. Palatal and buccal pedicle paths were used in 4 and 10 cases, respectively, for vascular anastomosis. The implant coverage rates of the DCIA and fibular free flaps were 87.2% and 92.6%, respectively (p > 0.05). CONCLUSION Anterior maxillary defects reconstructed with the DCIA and fibular free flaps are reliable methods. Furthermore, the palatal and buccal paths are recommended for vascular anastomosis.

Abstract
When surgery is performed to remove aggressive cancer, the extent of the lesion commands the amount of tissue removed. The removal of extensive tissue such as crucial landmarks complicates prosthesis design. This clinical report describes the prosthetic reconstruction of a patient who underwent tumor resection of the upper lip, anterior portion of the nasal cavity, and cartilaginous portion of the nasal septum, as well as subsequent radiation therapy. The prosthetic rehabilitation consisted of magnetic attachments, eyeglasses, and silicone adhesives. The applied technique effectively covered the site of squamous cell carcinoma removal providing natural color and form.

Virtual Surgical Planning and Customized Subperiosteal Titanium Maxillary Implant (CSTMI) for Three Dimensional Reconstruction and Dental Implants of Maxillary Defects after Oncological Resection: Case Series. J Clin Med 2022; 11:jcm11154594. [PMID: 35956210 PMCID: PMC9369575 DOI: 10.3390/jcm11154594] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 07/29/2022] [Accepted: 07/31/2022] [Indexed: 11/17/2022] Open
Abstract
Maxillectomies cause malocclusion, masticatory disorders, swallowing disorders and poor nasolabial projection, with consequent esthetic and functional sequelae. Reconstruction can be achieved with conventional approaches, such as closure of the maxillary defect by microvascular free flap surgery or prosthetic obturation. Four patients with segmental maxillary defects that had been reconstructed with customized subperiosteal titanium maxillary implants (CSTMI) through virtual surgical planning (VSP), STL models and CAD/CAM titanium mesh were included. The smallest maxillary defect was 4.1 cm and the largest defect was 9.6 cm, with an average of 7.1 cm. The reconstructed maxillary vertical dimension ranged from 9.3 mm to 17.4 mm, with a mean of 13.17 mm. The transverse dimension of the maxilla at the crestal level was attempted to be reconstructed based on the pre-excision CT scan, and these measurements ranged from 6.5 mm in the premaxilla area to 14.6 mm at the posterior level. All patients were rehabilitated with a fixed prosthesis on subperiosteal implants with good esthetic and functional results. In conclusion, we believe that customized subperiosteal titanium maxillary implants (CSTMI) are a safe alternative for maxillary defects reconstruction, allowing for simultaneous dental rehabilitation while restoring midface projection. Nonetheless, prospective and randomized trials are required with long-term follow-up, to assess its long-term performance and safety.

Abstract
(1) Background: Nowadays, microvascular grafts are the gold standard in the reconstruction of midface defects after maxillectomy, however, not all patients may qualify for this type of surgery. The purpose of present study is to evaluate the benefits of alternative reconstruction methods such as full-thickness skin grafts for these conditions. (2) Methods: The research group consisted of 37 patients who underwent maxillectomy due to cancer of the mid-face and had full-thickness skin graft reconstruction. The study covered the period from 2011 to 2020. (3) Results: Based on the clinical examination and the subjective assessment of patients, a positive effect of the use of free skin grafts on their convalescence and rehabilitation was found. In particular, they contributed to the reduction in postoperative pain and pain associated with prosthetic stages (VAS Scale). (4) Conclusion: Full-thickness skin grafts in combination with individual prosthetic restorations are a good alternative to rehabilitation in patients who do not qualify for microsurgical treatment.

Abstract
Purpose of the Study Patients undergoing ablative tumor surgery of the midface are faced with functional and esthetic issues. Various reconstructive strategies, such as implant-borne obturator prostheses or microvascular tissue transfer, are currently available for dental rehabilitation. The present study shows the first follow-up of patients treated with patient-specific implants (IPS Implants® Preprosthetic) for the rehabilitation of extended maxillary defects following ablative surgery. Patients and Methods All patients treated with patient specific implants due to postablative maxillary defects were included. 20 implants were placed in the 19 patients (bilateral implants were placed in one of the cases). In 65.75% of the cases, resection was performed due to squamous cell carcinoma. In addition to the primary stability, the clinical implant stability, soft tissue management, successful prosthodontic restoration, and complications were evaluated at a mean follow-up period of 26 months. Results All patient-specific implants showed primary stability and were clinically stable throughout the observation period. Definitive prosthodontic restorations were performed in all patients. No implant loosening was observed. Major complications occurred only in previously irradiated patients with insufficient soft tissue conditions (p = 0.058). Minor complications such as exposure of the underlying framework or mucositis were observed, but they never led to failure of restorations or implant loss. Conclusions Treatment of postablative maxillary defects with patient-specific implants offers a safe alternative with predictable results for full and rapid dental rehabilitation, avoiding time-consuming augmentation procedures and additional donor-site morbidity.

Abstract
Background Reconstruction of maxillary defect resulting from trauma or oncology surgery is of great importance for patients with physical and psychological complications. The virtual surgical planning (VSP) and 3D printing technics had been used in recent years which simplified the surgical procedure and promoted success and accuracy. To assess the accuracy and outcome of VSP surgery, here we report our experience in maxillary reconstruction retrospectively. Method Patients who received maxillary defect reconstruction from 2013 to 2020 were analyzed retrospectively. These patients were divided into two groups. Group 1 received VSP and 3D printed guiding plates in the surgery, while group 2 underwent free-hand surgery (FHS). Patients with different vertical and horizontal defects were classified according to Brown and Shaw classification. Clinical information and postoperative complications of all patients were collected. For patients with unilateral maxillary defect, orbit volume, orbit height, and the contour of the reconstructed side were compared with the normal side. Result Thirty-four patients who achieved the criteria were analyzed, of which 20 patients underwent VSP surgery. There were primary and secondary reconstruction cases in both two groups. Vascularized iliac crest flap was used in three cases, and fibula flap was performed in the other cases. One flap collapse occurred in FHS group. Seven patients in VSP group received dental implants, while the number in FHS group was 0. In vertical class III cases, the differences in orbit height (ΔD) and orbit volume (ΔV) between normal side and reconstructed side were measured and compared in the two groups. The mean ΔD is 1.78 ± 1.33 mm in VSP group and 4.25 ± 0.95 mm in FHS group, while the mean ΔV is 2.04 ± 0.85 cm3 in VSP group and 3.25 ± 0.17 cm3 in FHS group. The alterations of orbit height and volume in VSP group were much smaller than that in FHS group with statistical significance. From the perspective of aesthetics, the color-gradient map indicates a more symmetric and smoother curve of post-operation appearance in VSP group. Conclusion Compared with traditional free-hand surgical technics, VSP and 3D printing guiding plates can allow for a more accurate maxillary reconstruction with improved aesthetics.

Abstract
OBJECTIVE To evaluate the feasibility and clinical effect of facial-submental artery island flap (FSAIF) in the repair of palatal defects, and to provide reference for the clinical application of submental artery island flap. METHODS Nine patients with palatal defects, the range of nasal palatal perforation defects were 3 cm × 4cm to 3 cm × 6 cm (median 3 cm × 5.4 cm), were repaired by FSAIF, and the sizes of FSAIF were 4 cm × 9cm to 4 cm × 12 cm (median 4 cm × 10.4 cm,). Postoperative clinical efficacy was evaluated, including infection and necrosis of mucosal flap and postoperative palatal fistula perforation. Patients were followed up to evaluate their chewing, swallowing, speech function, and satisfaction of appearance. RESULTS All patients were successfully repaired with FSAIF. Followed up 13∼35 months, there was no palatal fistula perforation in all patients. The speech, agitation, and swallowing function were not affected and the patients were satisfied with the appearance. CONCLUSION FSAIF is a safe and reliable method for palatal defect repair.

Abstract
Reconstruction of the complex anatomy and aesthetics of the midface is often a challenge. A careful understanding of this three-dimensional (3D) structure is necessary. Anticipating the extent of excision and its planning following oncological resections is critical. In the past over two decades, with the advances in microsurgical procedures, contributions toward the reconstruction of this area have generated interest. Planning using digital imaging, 3D printed models, osseointegrated implants, and low-profile plates, has favorably impacted the outcome. However, there are still controversies in the management: to use single composite tissues versus multiple tissues; implants versus autografts; vascularized versus nonvascularized bone; prosthesis versus reconstruction. This article explores the present available options in maxillary reconstruction and outlines the approach in the management garnered from past publications and experiences.

Abstract
PURPOSE OF REVIEW The present review describes the latest development of 3D virtual surgical planning (VSP) and computer aided design (CAD) for reconstruction of maxillary defects with an aim of fully prosthetic rehabilitation. The purpose is to give an overview of different methods that use CAD in maxillary reconstruction in patients with head and neck cancer. RECENT FINDINGS 3D VSP enables preoperative planning of resection margins and osteotomies. The current 3D VSP workflow is expanded with multimodal imaging, merging decision supportive information. Development of more personalized implants is possible using CAD, individualized virtual muscle modelling and topology optimization. Meanwhile the translation of the 3D VSP towards surgery is improved by techniques like intraoperative imaging and augmented reality. Recent improvements of preoperative 3D VSP enables surgical reconstruction and/or prosthetic rehabilitation of the surgical defect in one combined procedure. SUMMARY With the use of 3D VSP and CAD, ablation surgery, reconstructive surgery, and prosthetic rehabilitation can be planned preoperatively. Many reconstruction possibilities exist and a choice depends on patient characteristics, tumour location and experience of the surgeon. The overall objective in patients with maxillary defects is to follow a prosthetic-driven reconstruction with the aim to restore facial form, oral function, and do so in accordance with the individual needs of the patient.

MATERIALS IN MEDICINE 2019; 30:125. [PMID: 31728639 DOI: 10.1007/s10856-019-6326-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Accepted: 10/23/2019] [Indexed: 06/10/2023]
Abstract
OBJECTIVE To evaluate the clinical outcomes of reconstruction of maxillary class III defect using 3D-printed titanium mesh. METHODS Twelve patients with maxillary class III defect from April 2015 to December 2016 were retrospectively studied. A 3D individualized maxillary stereo model based on mirror images of the unaffected maxilla was obtained to fabricate an anatomically adapted titanium mesh using computer-assisted design and manufacture. The individual titanium mesh was inserted into the maxillary class III defect after total maxillectomy. The incidence of postoperative complications was evaluated. The postoperative orbital volume and protrusion degree of eye were measured. RESULTS All patients were satisfied with their postoperative facial symmetry, without developing diplopia or endophthalmos. The postoperative orbital volumes were 26.41 ± 0.52 mL on the affected side and 26.55 ± 0.45 mL on the unaffected side. The postoperative protrusion degrees of affected and unaffected eyes were 16.21 ± 0.48 and 16.82 ± 0.79 mm, respectively. Titanium mesh exposure was observed in 2 patients and mild limitation of mouth opening was observed in 4 patients who underwent postoperative radiotherapy. CONCLUSION Reconstruction of maxillary class III defect with 3D-printed titanium mesh can achieve successful clinical outcomes, which recovered orbital volume and protrusion degree of eye. Twelve patients with maxillary class III defect were satisfied with their postoperative facial symmetry, without developing diplopia or endophthalmos. We investigated that reconstruction of maxillary class III defect with 3D-printed titanium mesh can achieve successful clinical outcomes.

Reconstruction of maxillectomy and midfacial defects using latissimus dorsi-scapular free flaps in a comprehensive cancer center. Oral Oncol 2019; 99:104468. [PMID: 31678764 DOI: 10.1016/j.oraloncology.2019.104468] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 09/04/2019] [Accepted: 10/22/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND The standard of care for sinonasal malignancies is a large surgical resection followed by radiotherapy. Midfacial defects resulting from maxillectomy require a complex reconstruction procedure. Given their adaptability, chimeric flaps such as latissimus dorsi-scapular (LDS) free flaps appear to be a good option. MATERIAL & METHODS We performed a single-center retrospective study of consecutive patients with sinonasal cancers where a LDS free flap was used for reconstruction. We assessed the postoperative complications and the functional, aesthetic and oncologic outcomes. RESULTS Eighty-four patients were included. Primary tumors were staged as T4a in 68% of cases; 38.3% of the patients received induction chemotherapy and 82.7% received adjuvant radiotherapy. Based on our classification of midfacial and palatal defects, the majority of the patients (69%) had a type IIa with interruption of the three facial pillars. The orbital floor was removed in 55.9% of cases. The median follow-up was 45 months. Total flap necrosis with no possible revascularization occurred in 5.9% of cases. For the orbital reconstruction, a revision procedure was needed for necrosis and/or infection of the costal cartilage graft in eight cases (17%). More than 90% of the patients had no functional disorders regarding speaking, swallowing and chewing. Soft palate involvement was a prognostic factor of speech (p < 10-4) and swallowing (p = .005) disorders. Dental rehabilitation was realized in 70.2% of the patients. No severe complications were observed in the donor site, except for one seroma. CONCLUSION A LDS free flap is a reliable technique for the reconstruction of complex midfacial defects.

Abstract
BACKGROUND There is increasing evidence of benefits for the rehabilitation of Brown II defects with prosthesis in surgery. However, the current literature is sparse for maxillary tumour resection using osteotomy templates. OBJECTIVES To assess the accuracy of maxillectomy using a custom fabricated osteotomy template and to evaluate the prosthesis for surgical accuracy, appearance and functioning (speech, swallowing and occlusal force). METHODS Ten patients with Brown II defects caused by tumour resection were treated with precise partial maxillectomy using an osteotomy template. The immediate rehabilitation of the Brown II defect was completed with a prefabricated prosthesis. The post-operative three-dimensional images and the pre-operative virtual images were superimposed, and average deviation and maximum deviation were calculated. Speech intelligibility, swallowing, appearance and University of Washington Quality of Life Questionnaire (UW-QoL) were examined at 1, 3 and 6 months after surgery. Occlusal force was examined post-operatively at 6 months. RESULTS The maximum deviation between the actual and virtual surgery was 5.12 ± 0.44 mm, with an average of 1.02 ± 0.17 mm. Speech intelligibility, swallowing and UW-QoL improved significantly (P < .05) after wearing the prosthesis. The recovery index of the occlusal force on the affected side was 20.19%-32.28%. The skewed degree of the mouth corner, the difference in the height of the left and right lips, the maximum deviation distance and the change area volume decreased significantly (P < .05). CONCLUSION The precise rehabilitation of maxillary Brown II defects can be achieved using a prosthesis fabricated with an osteotomy template. The prosthesis restored appearance and functional capabilities (such as speech and occlusal force).

Abstract
BACKGROUND The resection of head and neck cancer can result in postoperative defect. Many patients have difficulty swallowing and masticating, and some have difficulty speaking. Various types of flaps are used for palatal reconstruction, but flap selection remains controversial. Therefore, our study will suggest which flap to choose during palatal reconstruction. METHODS Thirteen patients who underwent palatal reconstruction from 30 January, 1989 to 4 October, 2016 at our institution. Size was classified as small when the width was < 4 cm², medium when it was 4-6 cm², and large when it was ≥ 6 cm². Based on speech evaluation, the subjects were divided into a normal group and an easily understood group. After surgery, we assessed whether flap selection was appropriate through the evaluation of flap success, complications, and speech evaluation. RESULTS Defect size ranged from 1.5× 2.0 cm to 5.0× 6.0 cm. In four cases, the defect was in the anterior third of the palate, in eight cases it was in the middle, and there was one case of whole palatal defect. There were three small defects, two medium-sized defects, and eight large defects. Latissimus dorsi free flaps were used in six of the eight large defects in the study. CONCLUSION The key to successful reconstructive surgery is appropriate selection of the flap with reference to the characteristics of the defect. Depending on the size and location of the defect, the profiles of different flaps should be matched with the recipient from the outset.

Abstract
Maxillary defects can be resolved by prosthetic obturation, autologous tissue reconstruction, or a combination of both. However, there is still controversy in the selection of the optimal approach. Therefore, the aim of this study was to systematically review evidences comparing the performance of obturators and flaps in patients after maxillary oncological ablation. Both electronic and manual searching approaches were conducted to identify eligible evidence. Two reviewers independently assessed the risk of bias. In addition, the same reviewers independently extracted the data. Meta-analyses were performed using Revman 5.3, and best evidence synthesis was performed. Sixteen studies were included and a total of 528 participants were analyzed. All studies were assessed at low quality. Results of this meta-analysis showed weak evidence in the difference between obturators and flaps on the outcome regarding word intelligibility (P = 0.004) and masticatory efficiency (P = 0.002). However, no differences were detected regarding speech intelligibility and nasalance. All studies were compiled into the best evidence synthesis. The sum of 31 evidences was considered. Twelve evidences were evaluated at a moderate level, such as speech, mastication, pain, salivation, taste sensations, and mouth opening. Except the outcomes of word intelligibility, masticatory efficiency, and mouth pain, other moderate evidences showed no difference between obturators and flaps. In conclusion, both obturators and flaps might be effective in patients' rehabilitation functions after maxillary ablation. However, some advantages were observed when using surgical reconstruction over prosthetic rehabilitation. Additional high-quality studies are needed to provide more solid evidence before applying these results into clinical practice.

Abstract
BACKGROUND Reconstruction of large, composite defects in the craniofacial region has evolved significantly over the past half century. During this time, there have been significant advances in craniofacial and microsurgical surgery. These contributions have often been in parallel; however, over the past 10 years, these two disciplines have begun to overlap more frequently, and the techniques of one have been used to advance the other. In the current review, the authors aim to describe the available options for free tissue reconstruction in craniofacial surgery. METHODS A review of microsurgical reconstructive options of aesthetic units within the craniofacial region was undertaken with attention directed toward surgeon flap preference. RESULTS Anatomical areas analyzed included scalp, calvaria, forehead, frontal sinus, nose, maxilla and midface, periorbita, mandible, lip, and tongue. Although certain flaps such as the ulnar forearm flap and lateral circumflex femoral artery-based flaps were used in multiple reconstructive sites, each anatomical location possesses a unique array of flaps to maximize outcomes. CONCLUSIONS Craniofacial surgery, like plastic surgery, has made tremendous advancements in the past 40 years. With innovations in technology, flap design, and training, microsurgery has become safer, faster, and more commonplace than at any time in history. Reconstructive microsurgery allows the surgeon to be creative in this approach, and free tissue transfer has become a mainstay of modern craniofacial reconstruction.

Abstract
Tissue regeneration in otorhinolaryngology-head and neck surgery is a diverse area filled with specialized tissues and functions. Head and neck structures govern many of the 5 senses, swallowing, breathing, communication, facial animation, and aesthetics. Loss of these functions can have a severe negative effect on patient quality of life. Regenerative medicine techniques have the potential to restore these functions while minimizing the risks associated with traditional reconstruction techniques. This article serves as a review and update on some of the regenerative medicine research in this field. A description of the predominant clinical problems is presented, followed by a discussion of some of the most promising research working toward a solution. There are many noteworthy findings appropriate for inclusion, but limitations preclude mention of them all. This article focuses on laryngeal surgery, craniofacial reconstruction and plastic surgery, and otology and hearing.
