Comparison between one-jaw and two-jaw designs in virtual surgery planning for patients with class III malocclusion.

Orthognathic surgery is highly effective for treating maxillomandibular discrepancies in patients with class III malocclusion. However, whether one- or two-jaw surgery should be selected remains controversial. Our study aimed to evaluate quantitative differences between one-jaw and two-jaw surgical designs. In total, 100 consecutive patients with skeletal class III malocclusion who underwent orthognathic surgery with preoperative three-dimensional simulation between August 2016 and November 2021 were recruited. Based on the same final occlusal setup, a two-jaw surgery design and two types of one-jaw design were created. In total, 400 image sets, including preoperative images and three types of surgical simulation, were measured and compared. The one-jaw mandibular setback design led to improvement in most cephalometric measurements and facial symmetry. Although the one-jaw maxillary advancement design improved the ANB angle and facial convexity, it induced maxillary protrusion and reduced facial symmetry. Compared with the other designs, the two-jaw design provided significantly closer cephalometric measurements to the normative values, better symmetry, and less occlusal cant. Overall, the two-jaw design provided a quantitatively better facial appearance in terms of symmetry, proportion, and profile. Although an optimal surgical design necessitates thorough preoperative evaluation and a shared decision-making process, two-jaw surgery can be considered for improving overall facial esthetics and harmony.

Two-flap technique with interpositional dermofat graft for anterior oronasal fistula closure in patients with cleft: A case series.

BACKGROUND: Oronasal fistula at the anterior hard palate is one of the common sequelae after cleft surgery, and the leakage negatively affects the patient's quality of life. Although several surgical techniques have been proposed for reconstruction, it remains challenging because of the scarred regional tissue with a high rate of fistula recurrence. In this study, we present the anterior oronasal fistula repair using a two-flap technique with an interpositional dermofat graft (DFG). METHODS: A retrospective review of anterior oronasal fistula repair performed by the senior author between April 2018 and August 2022 at the Craniofacial Center was conducted. Patients who underwent a fistula repair using the technique were further identified and investigated. RESULTS: Thirty-four operations were performed using the technique, and 31 fistulas were completely closed, with a success rate of 91.2%. The fistula symptom improved but persisted postoperatively in 3 patients, of whom 2 patients underwent a second fistula repair using the same procedure, resulting in successful closure. Fistula recurrence was significantly correlated with fistula size (p = 0.04). The DFG was simultaneously utilized for nasal dorsum and/or vermillion reconstruction in 28 cases. CONCLUSION: The two-flap technique enabled tension-free approximation, and the interpositional DFG facilitated watertight closure of the fistula, resulting in a high success rate of anterior oronasal fistula repair. The fistula closure could be combined with other revisional procedures for cleft-related deformities, where the DFG was simultaneously utilized.

Secondary Bilateral Cleft Rhinoplasty: Achieving an Aesthetic Result.

BACKGROUND: Secondary rhinoplasty in patients with bilateral cleft lip poses ongoing challenges and requires a reliable method for achieving optimal outcomes. OBJECTIVES: The purpose of this study was to establish a safe and effective method for secondary bilateral cleft rhinoplasty. METHODS: A consecutive series of 92 skeletally matured patients with bilateral cleft lip and nasal deformity were included. All had undergone secondary open rhinoplasty, performed by a single surgeon, with the use of bilateral reverse-U flap and septal extension graft between 2013 and 2021. Medical records of these 92 patients were reviewed to assess the clinical course. The three-dimensional anthropometric analysis and panel assessment of 32 patients were performed to evaluate the aesthetic improvement using an age-, sex-, and ethnicity-matched normal control group for comparisons. RESULTS: The methods showed statistically significant improvement in addressing short columella (columellar height), short nasal bridge (nasal bridge length), de-projected nasal tip (nasal tip projection, nasal dorsum angle), poorly defined nasal tip (nasal tip angle, dome height, and panel assessment), and transversely oriented nostrils (columellar height, alar width, nostril type). Importantly, these improvements were accompanied by a low complication rate of 4%. However, upper lip deficiency over the upper lip angle and labial-columellar angle remains without significant improvement. CONCLUSIONS: This study described the effective secondary rhinoplasty that was composed of bilateral reverse-U flap and septal extension graft with acceptable outcome. The 3D anthropometric analysis and panel assessment clarified that our rhinoplasty procedure could bring the nasal morphology in the patients closer to the normal data.

Facial Palsy after Orthognathic Surgery: Incidence, Causative Mechanism, Management, and Outcome.

BACKGROUND: Facial palsy after orthognathic surgery is an uncommon but serious complication causing dissatisfaction and affecting quality of life. The occurrence could be underreported. Surgeons need to recognize this issue regarding the incidence, causative mechanism, managements, and outcome. METHODS: A retrospective review of orthognathic surgery records between January of 1981 and May of 2022 was conducted in the authors' craniofacial center. Patients who developed facial palsy after the surgery were identified, and demographics, surgical methods, radiologic images, and photographs were collected. RESULTS: A total of 20,953 sagittal split ramus osteotomies (SSROs) were performed in 10,478 patients. Twenty-seven patients developed facial palsy, resulting in an incidence of 0.13% per SSRO. In a comparison of SSRO technique, the Obwegeser-Dal Pont technique using osteotome for splitting had higher risk of facial palsy than the Hunsuck technique using the manual twist splitting ( P < 0.05). The severity of facial palsy was complete in 55.6% of patients and incomplete in 44.4%. All patients were treated conservatively, and 88.9% attained full recovery in a median duration of 3 months [interquartile range (IQR), 2.75 to 6 months] after surgery, whereas 11.1% attained partial recovery. Initial severity of facial palsy predicted the timing of recovery, with incomplete palsy patients having faster median recovery (3 months; IQR, 2 to 3 months) than the complete palsy patients (6 months; IQR, 4 to 6.25 months) ( P = 0.02). CONCLUSIONS: The incidence of facial palsy after orthognathic surgery was 0.13%. Intraoperative nerve compression was the most likely causative mechanism. Conservative treatment is the mainstay of therapeutic strategy, and full functional recovery was anticipated. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, IV.

Long-term survival of the Sister Mary Joseph nodule originating from breast cancer: A case report.

BACKGROUND: A Sister Mary Joseph nodule (SMJN) is an uncommon cutaneous metastasis found in the umbilicus, indicating an advanced malignancy. SMJNs typically originate from intra-abdominal sources, rarely from breast cancer. Diagnosis suggests a poor prognosis with a median survival of approximately 8 mo after detection. Managing patients with SMJNs is challenging, as most receive limited palliative care only. The optimal strategy for long-term survival of these patients remains unclear. CASE SUMMARY: A 58-year-old female, previously diagnosed with right breast cancer 17 years ago and underwent breast-conserving surgery, adjuvant radiotherapy, and endocrine therapy, presented with a 2-cm umbilical nodule. Thirteen years previously, metastases were detected in the right supraclavicular, infraclavicular, hilar, and mediastinal lymph nodes. An umbilical nodule emerged four years before the date of presentation, confirmed as a skin metastasis of primary breast cancer upon excisional biopsy. Despite initial removal, the nodule recurred and grew, leading to her referral to our hospital. The patient underwent extensive excision of the umbilical tumor and immediate abdominal wall reconstruction. Endocrine therapy was continued postoperatively. Five years later, no local recurrence was observed, and the patient continued to work full-time, achieving over 9 years of survival following SMJN diagnosis. CONCLUSION: This case study aimed to identify the optimal strategy for achieving extended survival outcomes in patients with SMJN through comprehensive treatment. We presented a case of the longest survival in a patient after undergoing a multidisciplinary treatment regimen. Our findings underscore the significance of adopting a multimodal treatment approach comprising timely and wide excision along with adjunctive therapy. This approach can control the disease, prolong survival, and improve the quality of life in patients with SMJN.

Modified Furlow palatoplasty using small double-opposing Z-plasty: Long-term outcome and comparison with two-flap palatoplasty.

BACKGROUND: The post-palatoplasty velopharyngeal function needs to be evaluated through long-term follow-up, but such reports are limited in the literature and there has been no consensus as to which surgical technique yields optimal velopharyngeal function with minimum complication rate. This study aimed to evaluate the long-term outcome of the modified Furlow palatoplasty using small double-opposing Z-plasty (small-DOZ). METHODS: A retrospective review of consecutive patients who received palatoplasty performed by the senior author between January 2000 and March 2014 was conducted. Non-syndromic patients who underwent palatoplasty before the age of 18 months and followed-up until at least 9 years of age were included. Comparisons between the small-DOZ and two-flap methods for soft palate repair were made. RESULTS: A total of 196 small-DOZ and 167 two-flap palatoplasty patients were eligible in the study. Among the small-DOZ palatoplasty patients, 1 patient (0.5%) developed oronasal fistula, and 18 patients (9.2%) received velopharyngeal insufficiency (VPI) surgery (10 patients at preschool age and 8 at nine years of age). Compared with the small-DOZ palatoplasty, the oronasal fistula rate, VPI surgery rate, and the need for myringotomy tube insertion were significantly higher in the two-flap group (p =0.01, <0.01, <0.01, respectively). Patients who developed oronasal fistula had significantly higher likelihood of having velopharyngeal insufficiency (p < 0.01). CONCLUSION: The small-DOZ provided successful palatal repair with low rates of oronasal fistula and VPI in the long-term. Wound closure under minimal tension facilitated to avoid oronasal fistula. Reconstruction of the functional muscle sling enabled to achieve normal velopharyngeal function with favorable speech outcome and middle ear function.

Septal extension graft in cleft rhinoplasty: Patients with secondary unilateral cleft lip nasal deformity.

BACKGROUND: Tip refinement procedure is still controversial in secondary unilateral cleft rhinoplasty. The aim of this study was to assess whether septal extension graft improved nasal and tip deformity and achieved a normal profile with clinical and 3D morphometric analyses. METHODS: A consecutive series of 194 skeletally mature patients with unilateral cleft were included and analyzed. All had undergone secondary open rhinoplasty, performed by a single surgeon, with the use of septal extension graft between 2013 and 2021. Clinical data were collected, and 3D morphometric measurements were performed. An age-, sex-, and ethnicity-matched normal group was included for comparisons. RESULTS: Our standard procedures included open approach combining reverse U incision, septal extension graft, dorsal augmentation, lip revision, and vermilion augmentation. The postoperative outcome showed significantly increased numerical values (nasal bridge length, nasal height, nasal tip projection, nasal dorsum angle, columellar angle, columellar-lobule angle, nostril height ratio, nasal surface area, nasal volume) and decreased numerical values (alar width, tip/middle deviation, nasal tip angle, labial-columellar angle) than the preoperative morphology. The postoperative measurement showed significantly higher numerical values (nasal protrusion, tip/middle deviation, nasal dorsum angle), and lower numerical values (columellar-lobule angle, nostril height ratio, alar width ratio) than the control group. CONCLUSION: This study revealed that our secondary cleft rhinoplasty significantly improved the under-projected, up-rotated, deviated, and poorly defined tip as well as short nasal bridge deformities. The technique could result in the nose of the patients with cleft lip nasal deformity being closer to that of the normative profile.

Avoiding Inferior Alveolar Nerve Injury During Sagittal Split Ramus Osteotomy.

Orthognathic surgery is highly effective in improving overall facial esthetics, in addition to achieving an ideal occlusion. Sagittal split ramus osteotomy (SSRO) of the mandible is the mainstay of modern orthognathic surgery, but intraoperative injury to the inferior alveolar nerve (IAN) remains one of the common complications. The authors report a case of 19-year-old male patient with left cleft lip and palate who received orthognathic surgery involving SSRO. The patient's right IAN ran close to the outer cortex of the mandible, but SSRO was successfully performed without injuring the nerve. Detailed preoperative evaluation using computed tomography images is essential. Blind splitting maneuvers during SSRO may cause IAN injury, and direct visualization inside the ramus helps to prevent injury to the nerve. Sagittal split ramus osteotomy could be considered as a viable option even when the IAN runs close to the outer cortex. This article describes SSRO procedures, highlighting the methods to avoid nerve injury.

Effective correction of columellar base deviation in primary unilateral cleft lip repair: A muscle-driven method.

SUMMARY: Columellar base deviation is a common and challenging deformity in patients with unilateral cleft lip. Debate still continues on its surgical correction without sufficient studies to establish an effective management. This article presents our experience in correcting the columellar base deviation with the muscle-driven method in primary lip repair. The key is to perform extensive muscle dissection and reconstruction. In the medial lip segment, muscle dissection is performed subcutaneously up to the contralateral nostril floor for effective lengthening and rotation. In the lateral lip segment, muscle dissection is executed in both submucosal and subcutaneous planes, and muscle component is extensively separated from the lip skin and buccal mucosa. The lateral muscle flap is advanced and reattached to the contralateral nostril floor and columellar base using a subcutaneous sustaining suture. Cinching suture between columellar base and alar base is performed. These two sutures help to centralize and over-correct the columellar base. Bilateral muscle components are re-oriented and approximated in a Z-plasty format for lengthening of the lip. The patients were followed up for at least 3 years. Quantitative measurements of deviation in columellar base angulation were executed, which revealed 55.8±2.6° (before nasoalveolar molding), 29.6±1.7° (after nasoalveolar molding), and 2.8±0.4° (postoperative follow-up), respectively. The muscle-driven method represents a safe and effective technique to correct columellar base deviation in patients with unilateral cleft lip.

Long-term treatment outcome of patients with complete bilateral cleft lip and palate: a retrospective cohort study.

BACKGROUND: Patients with cleft lip and palate have functional and esthetic impairment and typically require multiple interventions in their life. Long-term evaluation following a treatment protocol, especially for patients with complete bilateral cleft lip and palate (BCLP), is important but was rarely reported in the literature. PATIENTS AND METHODS: A retrospective review was conducted on all patients with complete BCLP born between 1995 and 2002 and treated at our center. Inclusion criteria were having adequate medical records and receiving continuous multidisciplinary team care at least until 20 years of age. Exclusion criteria were lack of regular follow-up and congenital syndromic abnormalities. The medical records and photos were reviewed, and facial bone development was evaluated using cephalometric analysis. RESULTS: A total of 122 patients were included, with a mean age of 22.1 years at the final evaluation in this study. Primary one-stage cheiloplasty was performed in 91.0% of the patients, and 9.0% underwent two-stage repair with an initial adhesion cheiloplasty. All patients underwent two-flap palatoplasty at an average of 12.3 months. Surgical intervention for velopharyngeal insufficiency was required in 59.0% of patients. Revisional lip/nose surgery was performed in 31.1% during growing age and in 64.8% after skeletal maturity. Orthognathic surgery was applied in 60.7% of patients with retruded midface, of which 97.3% underwent two-jaw surgery. The average number of operations to complete the treatment was 5.9 per patient. CONCLUSION: Patients with complete BCLP remain the most challenging group to treat among the cleft. This review revealed certain suboptimal results, and modifications have been made to the treatment protocol. Longitudinal follow-up and periodic assessment help to establish an ideal therapeutic strategy and improve overall cleft care.

Facial palsy after orthognathic surgery: A systematic review.

It was the aim of the systematic review to evaluate the incidence of facial palsy following orthognathic surgery, and to assess the possible mechanisms of injury, subsequent management, and eventual outcomes. The protocol of this systematic review was registered in the International Prospective Register of Systematic Reviews. A thorough search of PubMed, Scopus, Cochrane Library, and CINAHL databases up to April 2022 was conducted. In total, 34 articles were selected for this review, including 54 facial palsies in 53 patients. The incidence of facial palsy was estimated to range from 0.04% to 0.77%. Most of the possible etiologies proposed involved intraoperative nerve compression or postoperative edema. Physical therapy and steroid administration were the most frequently employed management approaches. Surgical exploration for the facial nerve was executed in one patient. Forty-three facial palsies (79.6%) attained complete recovery with conservative management, whereas 11 facial palsies (20.4%) continued to show incomplete recovery during the follow-up period. Earlier facial palsy onset (timing after surgery) was related to a higher risk of continuing palsy (p = 0.018). Within the limitations of this review it seems that facial palsy following orthognathic surgery should be treated conservatively whenever appropriate.

Use of a Surgical Microscope for Subperichondrial-Subperiosteal Dissection in Preservation Rhinoplasty: Ergonomic Considerations.

Preservation of anatomical components in rhinoplasty has gained increasing popularity over recent years. Given that elevation of the soft tissue envelope in a continuous subperiochondrial-subperiosteal dissection preserves soft tissues, vessels, nerves, and lymphatics, this procedure may result in faster healing time and less swelling and scarring. However, the technique requires a learning phase and can be challenging to perform because it typically requires meticulous dissection under surgical loupes. The dissection may thus be time-consuming and a burden for surgeons, especially in secondary rhinoplasty cases. Further, the potential risk of musculoskeletal discomfort and injury to the surgeon should not be overlooked; consideration for surgical ergonomics is needed to prevent injuries and enhance surgical performance. To address these issues, we propose the use of a surgical microscope for subperiochondrial-subperiosteal dissection in preservation rhinoplasty. A microscope enables clear visualization of the surgical field and allows surgeons to make precise and delicate manipulation maneuvers. Moreover, it may also enable surgeons to maintain an ideal ergonomic posture and neutral positioning of their joints, thereby reducing physical strain. A surgical microscope may thus be a useful tool for subperiochondrial-subperiosteal dissection by providing clear visualization of the surgical field and improved surgical ergonomics for surgeons.

Partial Second Toe Pulp Flap Transfer for the Coverage of Great Toe Hemipulp Flap Donor Site.

The great toe hemipulp flap transfer is a viable reconstructive method for finger pulp defect. However, early functional recovery of the donor foot is essential for returning to daily life activities, and functional and aesthetic restoration of the donor site remains challenging. We present a case in which the great toe hemipulp flap donor site was reconstructed with pedicled partial second toe pulp flap transfer, aiming for early recovery of the donor foot and aesthetically and functionally satisfactory donor-site reconstruction. A 62-year-old man underwent left little finger-pulp crush amputation in Tamai zone 2 and received free great toe hemipulp flap transfer. For the defect following flap harvest, the partial second toe pulp flap was elevated and transferred. The donor site of the partial second toe pulp flap was primarily closed. The postoperative course was uneventful, and the patient started walking on postoperative day 2. Postoperatively, the sensory recovery of the transferred flap was excellent, and the reconstructed great toe was functionally and aesthetically satisfactory. The pedicled partial second toe pulp flap transfer may be a viable alternative for the coverage of great toe hemipulp flap donor site.

Lymphatic-venous anastomosis for the treatment of refractory lymphatic ascites following radiation therapy: A case report.

Radical treatments for intra-abdominal malignancies disturb physiological lymphatic drainage and predispose the patients to lymphatic complications such as lymphatic ascites. Despite its infrequent occurrence, lymphatic ascites is a morbid complication, and a definitive treatment protocol for refractory cases has not been established. Surgical treatments are opted depending on the etiology, symptoms, and facility equipment. Lymphatic-venous anastomosis (LVA) bypasses the proximal lymphatic blockages and provides an alternative route for lymphatic fluid recirculation into the venous system, thereby improving the lymphatic congestion. Herein, we report the utility of LVA surgery in the treatment of refractory serous lymphatic ascites that developed after radiation therapy for cervical cancer in a 77-year-old woman. The patient had massive ascites and suffered from abdominal distention and anorexia for 1 year. The ascites was unresponsive to conservative treatment. Under local anesthesia, eight incisions were made in the lower extremities just above the lymphatic channels that were identified by indocyanine green lymphography, and a total of 14 LVAs were created. The postoperative course was uneventful, and the ascites improved significantly. The patient remained free from the recurrence of ascites during 3.5 years of postoperative follow-up. LVA surgery was effective for the improvement and long-term control of lymphatic ascites. This procedure may be a viable option for the management of lymphatic ascites.

Surgical Lymphoedema Treatment of Morbihan Disease: A Case Report.

ABSTRACT: Morbihan disease is a rare condition characterized by persistent erythema and solid edema of the upper two thirds of the face, leading to visual impairment and significant esthetic disfigurement. The underlying etiology of the disease remains uncertain, but its correlation with lymphoedema has been conjectured. Definitive treatment options are also lacking, and most current topical, systemic, and surgical interventions provide transient or partial results.In this report, we describe a case of Morbihan disease in a 32-year-old man. He suffered from erythema and swelling over the left periorbital region for 6 years, and was diagnosed with Morbihan disease. As the edema was unresponsive to drug therapy, he was referred to our department. Indocyanine green lymphography was performed, and the diagnosis of facial lymphoedema was confirmed. Manual lymphatic drainage was not effective, so we proceeded with surgical procedures. Lymphaticovenous anastomosis was performed to improve lymphatic drainage, and blepharoplasty was performed to debulk the enlarged tissue of lymphoedema. The visual field improved significantly, and the patient remains free from reexpansion of the lesion during the 1-year follow-up.The surgical approach for lymphoedema treatment can be a viable option for severe Morbihan disease unresponsive to nonsurgical therapies.

Acromioclavicular Joint Cyst Treated with Excision and Anterolateral Thigh Flap Reconstruction.

Acromioclavicular joint (ACJ) cysts are a rare clinical entity that can impair patients' cosmetic appearance as well as activities of daily living. Both nonsurgical and surgical treatments are available, but nonsurgical treatments are often associated with a high recurrence rate. Surgical excision can provide resolution of patients' symptoms, but excision of the cyst as monotherapy is also associated with recurrence. Therefore, various surgical techniques to prevent recurrence have been described, but there is no general consensus regarding the appropriate surgical methods. We describe the case of an 81-year-old man with a recurrent ACJ cyst. The cyst had been excised twice, but it recurred shortly after the excisions. We performed surgical resection and anterolateral thigh (ALT) flap reconstruction. The deteriorated ACJ capsule was repaired with durable fascia lata and the defect after tumor excision was obliterated with an ALT flap harvested from the same donor site as fascia lata. On the 12-month follow-up, the patient had no recurrence of the ACJ cyst. Our case suggests that excision of ACJ cysts as monotherapy is likely to fail, and fascia lata patch for durable ACJ capsule reconstruction can be a viable alternative preventing cyst recurrence.
