Objectives: Oral and maxillofacial surgeons must gain mastery of various approaches to the midface due to the increasing incidence, complexity, and severity of presenting midfacial fractures. Unlike in the case of other body parts, the need to preserve facial aesthetics makes it more difficult for the surgeon to select an approach for managing the facial injuries. The midfacial degloving (MFD) approach is a combination of intraoral and intranasal incisions made to access the midface without any external incision. The aim of the present study was to evaluate the efficacy of MFD in maxillofacial surgery and to assess its advantages and complications. Materials and Methods: The MFD approach was used in five cases, with three cases treated with open reduction and internal fixation and two cases operated on for posttraumatic deformity. Nasal dorsum augmentation was completed in three cases and nasal osteotomy was performed in one case. The bicoronal flap technique was combined with MFD for frontal bone augmentation in one case. The intraoperative time required for flap completion and the ease of performing the planned procedures were noted. Postoperative evaluation was done for reduction, aesthetics, function, and complications. Results: Access was excellent for performing all planned procedures. Average time spent for flap elevation and exposure of the midface was 63 minutes. Complications like postoperative swelling, infraorbital nerve paresthesia, and intranasal crusting were all transient. No long-term complications like stenosis of the nose, sneer deformity, or weakness of the facial muscles were noticed. Additionally, no complications were noted when MFD was combined with bicoronal flap. Conclusion: Though the MFD approach is technically demanding and takes more time than other facial approaches, it should be learned and applied by maxillofacial surgeons in selective cases, as it provides complete exposure of the midface without facial scarring.

A mucocele is an epithelium-lined, mucus-filled cavity in the paranasal sinuses. Mucocele may develop due to scarring and obstruction of the sinus ostium caused by midface sinus trauma, such as orbital bone fracture or endoscopic sinus surgery. The authors report two cases of orbital mucocele as complications following midface sinus injury (endoscopic sinus surgery in one case, and orbital fracture repair in the other). In both cases, imaging studies showed a large orbital mucocele accompanied by bony erosion and orbital wall remodeling, compressing the ocular muscle. Using an open approach, the lesion was excised and marsupialized. The symptoms resolved, and the postoperative eyeball position was normal. Orbital mucocele may cause serious complications such as ocular symptoms, orbital cellulitis, osteomyelitis, and the formation of an abscess with the potential to invade the brain. Therefore, surgeons should consider the possibility of mucocele as a late complication of surgery and initiate an immediate work-up and surgical treatment if needed.

Face transplantation has been reported over the last six years, and it started in 2004 with the announcement of Cleveland Clinic granting the world's first IRB approval to proceed with human face transplantation. Composite tissue allografts (CTAs) in the facial region are considered to be more immunogenic than other solid organ transplants, so these kinds of animal experiments were also considered as challengeable activities to the facial reconstructive surgeons. For the better understanding of CTAs in the oral and maxillofacial fields, we reviewed several recent articles about facial composite transplantation animal model, and summarized some knowledges of composite midface allotransplantation model with sensory and motor reinnervation in this review article.

Background: A 9-year-old male showed severe defects in midface structures, which resulted in maxillary hypoplasia, ocular hypertelorism, relative mandibular prognathism, and syndactyly. He had been diagnosed as having Apert syndrome and received a surgery of frontal calvaria distraction osteotomy to treat the steep forehead at 6 months old, and a surgery of digital separation to treat severe syndactyly of both hands at 6 years old. Nevertheless, he still showed a turribrachycephalic cranial profile with proptosis, a horizontal groove above supraorbital ridge, and a short nose with bulbous tip. Methods: Fundamental aberrant growth may be associated with the cranial base structure in radiological observation. Results: The Apert syndrome patient had a shorter and thinner nasal septum in panthomogram, PA view, and Waters' view; shorter zygomatico-maxillary width (83.5 mm) in Waters' view; shorter length between the sella and nasion (63.7 mm) on cephalogram; and bigger zygomatic axis angle of the cranial base (118.2°) in basal cranial view than a normal 9-year-old male (94.8 mm, 72.5 mm, 98.1°, respectively). On the other hand, the Apert syndrome patient showed interdigitating calcification of coronal suture similar to that of a normal 30-year-old male in a skull PA view. Conclusion: Taken together, the Apert syndrome patient, 9 years old, showed retarded growth of the anterior cranial base affecting severe midface hypoplasia, which resulted in a hypoplastic nasal septum axis, retruded zygomatic axes, and retarded growth of the maxilla and palate even after frontal calvaria distraction osteotomy 8 years ago. Therefore, it was suggested that the severe midface hypoplasia and dysostotic facial profile of the present Apert syndrome case are closely relevant to the aberrant growth of the anterior cranial base supporting the whole oro-facial and forebrain development.

Patients with thick skin mainly exhibit the aging processes of sagging, whereas patients with thin skin develop wrinkles or volume loss. Asian skin is usually thicker than that of Westerners; and thus, the sagging of skin due to aging, rather than wrinkling, is the chief problem to be addressed in Asians. Asian skin is also relatively large in area and thick, implying that the weight of tissue to be lifted is considerably heavier. These factors account for the difficulties in performing a facelift in Asians. Facelifts can be divided into forehead lift, midface lift, and lower face lift. These can be performed individually or with 2-3 procedures combined.

The emergence of vaccines for coronavirus disease 2019 (COVID-19) raises risk of possible adverse events from interaction between the vaccines and facial aesthetic care. A 47-year-old female with no medical comorbidities visited our emergency room due to midface painful swelling after 3 hours following receiving the second dose of the messenger RNA BNT162b2 COVID-19 vaccine. About 14 years ago, she underwent nonsurgical augmentation on the nasojugal groove with a calcium hydroxylapatite dermal filler. We performed incision and drainage under general anesthesia on the next day. During operation, yellowish pus-like materials bulged out. After an operation, we performed a combination therapy with antibiotics and methylprednisolone. Her symptoms improved day by day after surgery, and then a complete recovery was achieved at 3 weeks after the treatment. In conclusion, providers of aesthetic procedures are to be aware of the potential risks of such vaccines for patients who already had or seek to receive dermal filler injections.

Purpose: Maxillectomy for malignant tumor resection often leads to functional and aesthetic sequalae. Reconstruction following maxillectomy has been a challenging problem in the field of head and neck cancer surgery. In this article, we described three dimensional midface reconstructions using free flaps and their functional and aesthetic outcomes. Methods: We reconstructed 35 cases of maxillectomy defects using 9 radial forearm free flaps, 7 lattisimus dorsi musculocutaneous free flaps, 6 rectus abdominis musculocutaneous free flaps, 4 fibular osteocutaneous free flaps, and 9 anterolateral thigh free flaps, respectively. We classified post-maxillectomy defects by Brown's classification. 1 Articulation clarity was measured with picture consonant articulation test. Swallowing function was evaluated with the University of Washington quality-of-life Head and Neck questionnaire by 4 steps.2 Aesthetic outcomes were checked to compare preoperative with postoperative full face photographs by 5 medical doctors who did not involve in our operation. Results: The average articulation clarity was 92.4% (100-41.9%). 27 (81.9%) patients were able to eat an unrestricted diet. Aesthetic results were considered excellent in 18 patients (51.4%). Functional results were best in the group reconstructed with fibular osteocutaneous free flap. Considering the range of wide excision, aesthetic results is best in the group reconstructed with anterolateral thigh free flap. Conclusion: The free flap is a useful technique for the reconstruction of the midface leading to good results, both functionally and aesthetically. Especially, because osteocutaneous flap such as fibular osteocutaneous free flap offered bone source for osteointegrated implant, It produces the best functional results. And perforator flap like as anterolateral thigh free flap reliably provides the best aesthetic results, because it provides sufficient volume and has no postoperative volume diminution.

Bulging of the lower eyelid & tear trough groove is regarded as a sign of aging. In the past, the surgical excision of the fat pad has been the mainstray of the management of lower palpebral bag in cosmetic blepharoplasty, Recently, fat pad sliding method has been introduced to make more attractive lower eyelids. We used the fat pad for covering the hollowness of the lower eye lid. And we use redundant fat pad for filling & augmentation of the lower eye lid by reflexion. Redraping of the orbicularis arc, with its accompanying midfacial fat repositioning, anatomically restores the cheek and lower lid to make more youthful contour. By redraping and fixing the orbicularis arc on the medial surface of the orbital rim, it becomes a more attractive midface and may prevent of ectropion. From August, 2002 to July, 2004 in correction of lower palpebral bulge & tear trough groove, these two technique were performed in 42 consecutive individuals (84 lower eyelid) for two-year period. Follow up ranged from 3 to 15 months. (an average of 9 months) Palpebral bulge & tear trough groove were corrected and obtained a youthful midface. Complication was rare. The advantages of these techniques are that: prevent in of secondary palpebral bulge and irregularity of lower eyelid by using of reflexed fat fad; prevent in of ectropion. Thus an attractive midface is obtained by redraping of orbicularis arc.

Cleft lip and palate patients show midface hypoplasia, maxillary hypoplasia due to scar of previous surgery, and manifest as a class III malocclusion, retruded midface and shallow palate. These deformities have been treated with traditional orthognathic surgery. Although conventional Le Fort I osteotomy was performed on most cleft patinets with midface hypoplasia, it showed limited amount of maxillary advancement and high relapse tendency. Recently, when great amount of advancement are required in severe maxillary hypoplasia, distraction osteogenesis using RED system is widely used. But, several months of consolidation period is needed after distraction osteogenesis, occlusal relationship is not stable until mandibular setback surgery has done in mandibular hyperplasia cases and during these period, patients may feel discomfort. We present clinical cases of immediate rigid internal fixation after completion of maxillary distraction using RED system and simultaneous mandibular setback procedure in adult cleft and lip patients who show both maxillary hypoplasia and mandibular prognathism.
