Background Sternoclavicular joint (SCJ) osteomyelitis is a rare pathology requiring urgent intervention. Several operative approaches have been described with conflicting reports. Here, we present a multi-institutional study utilizing multiple surgical pathways for SCJ reconstruction. Methods A multi-institutional retrospective cohort study was conducted to identify patients who underwent surgical repair for sternoclavicular osteomyelitis between 2008 and 2019. Patients were stratified according to reconstruction approach: single-stage reconstruction with advancement flap and delayed-reconstruction with flap following initial debridement. Demographics, operative approach, type of reconstruction, and postoperative outcomes were analyzed. Results Thirty-two patients were identified. Mean patient age was 56.2±13.8 years and 68.8% were male. The average body mass index (BMI) was 30.0±8.8 kg/㎡. The most common infection etiologies were intravenous drug use and bacteremia (both 25%). Fourteen patients (43.8%) underwent one-stage reconstruction and 18 (56.2%) underwent delayed two-staged reconstruction. Both single and delayed-stage groups had comparable rates of reinfection (7.1% vs. 11.1%, respectively), surgical site complications (21.4% vs. 27.8%), readmissions (7.1% vs. 16.6%), and reoperations (7.1% vs. 5.6%; all P>0.05). The single-stage reconstruction group had a significantly lower BMI (26.2±5.7 kg/㎡ vs. 32.9±9.1 kg/㎡; P<0.05) and trended towards shorter hospital length of stay (11.3 days vs. 17.9 days; P=0.01). Conclusions Both single and delayed-stage approaches are appropriate methods with comparable outcomes for reconstruction for SCJ osteomyelitis. When clinically indicated, a single-stage reconstruction approach may be preferable in order to avoid a second operation as associated with the delayed phase, and possibly shortening total hospital length of stay.

Background: The paradigm of tonsillectomy has shifted from a treatment of recurrent throat infection to one of multi-discipline management modalities of sleep-disordered breathing (SDB). While tonsillectomy as a treatment for throat problems has been performed almost exclusively by otorhinolaryngologists, tonsillectomy as a part of the armamentarium for the multifactorial, multidisciplinary therapy of sleep-disordered breathing needs a new introduction to those involved in treating SDB patients. This study has its purpose in sharing a series of tonsillectomies performed at the Seoul National University Dental Hospital for the treatment and prevention of SDB in adult patients. Methods: Total of 78 patients underwent tonsillectomy at the Seoul National University Dental Hospital from 1996 to 2015, and 23 of them who were operated by a single surgeon (Prof. Jin-Young Choi) were included in the study. Through retrospective chart review, the purpose of tonsillectomy, concomitant procedures, grade of tonsillar hypertrophy, surgical outcome, and complications were evaluated. Results: Twenty-one patients diagnosed with SDB received multiple surgical procedures (uvulopalatal flap, uvulopalatopharyngoplasty, genioglossus advancement genioplasty, tongue base reduction, etc.) along with tonsillectomy. Two patients received mandibular setback orthognathic surgery with concomitant tonsillectomy in anticipation of postoperative airway compromise. All patients showed improvement in symptoms such as snoring and apneic events during sleep. Conclusions: When only throat infections were considered, tonsillectomy was a procedure rather unfamiliar to oral and maxillofacial surgeons. With a shift of primary indication from recurrent throat infections to SDB and emerging technological and procedural breakthroughs, simpler and safer tonsillectomy has become a major tool in the multidisciplinary treatment modality for SDB.

Purpose: The epicanthus is a specific feature in Asian. Many techniques have been described to eliminate the epicanthal fold: resection of glabellar skin, resection of medial canthal skin, V-Y advancement, V-W technique, modified Z-plasty, multiple Z-plasties, and others. The authors observed postoperative epiphora after correction of epicanthal fold by periciliary skin flap without damaging lacrimal duct. Methods: A 19-year-old woman underwent non-incisional blepharoplasty, septorhinoplasty, and periciliary epicanthoplasty. On her history, she didn't have any symptom of epiphora preoperatively. And there was no specific complaint of epiphora during the postoperative two weeks. However epiphora got worse from one month after the surgery. She was out of this country, so the patient re-visited the clinic on the postoperative six months for this on-going symptom. On an ophthalmologic examination, patient's lacrimal duct and sac was intact but both lacrimal puncta of the patient were covered with a thin membrane. This membrane was punctuated by a 25 gauge needle and dilated with a standard dilator. Results: After ophthalmologic treatment, no recurrence was observed during five weeks of follow-up periods. Conclusion: Both lacrimal puncta of the patient were only covered with membranes. And we could not confirm the direct relationship between periciliary epicanthoplasty and postoperative epiphora. The probable factors will be a predisposing narrowed punctum, post operative peri-punctal edema and decrease in muscular function of orbicularis oculi.

Purpose: The purpose of this study was to report the surgical outcome of reconstruction of neglected chronic Achilles tendon ruptures with various methods including Achilles tendon allograft. Materials and Methods: Between October 2003 and November 2008, 8 consecutive neglected chronic Achilles tendon ruptures with the defect gap of more than 4 cm underwent surgical reconstruction including V-Y advancement, gastrocnemius fascial turn-down flap, flexor hallucis longus transfer and Achilles tendon allograft. There were 7 males and 1 female who were evaluated at more than 18 months after surgery. At the time of followup, all patients were assessed with regard to postoperative complications, their self-reported level of satisfaction, the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale, 10 repetitive single heel rise, single leg hopping test, and ankle range of motion. Results: The AOFAS score increased from average 71.4 (50-87) to 96.4 (86-100). All patients were able to perform 10-repetitive single heel raise and single leg hopping at the latest follow up. No patient experienced wound complications and deep infection. Six patients were rated as 'excellent' and the other two as 'good'. Conclusion: Neglected chronic Achilles tendon ruptures could be successfully treated with careful selection of the reconstruction method according to the amount of defect gap. With an extensive defect, Achilles tendon allograft can be a good option when the reconstruction is not feasible otherwise.

Purpose: The importance of the deformities in alar - columellar complex has been underestimated in Asian ethnic groups for the last decades. Fortunately, with increasing familiarity of the open rhinoplasty techniques, the anatomic details of the nasal tip have been pointed up. Definitely, having an interest and demand for improving the sub - normal relationship between the alar rim and columella are indebted for such growing of knowledge about nasal tip anatomy. However, it is true that any single procedure is not settled as versatile and fully confident modality to correct the retracted notching of the alar rim. With this article, I should like to propose another useful option for treating retracted ala. Methods: The author has tried to correct alar rim retraction by means of: (1) Triangular onlay septal cartilage graft on the lower lateral cartilage with the medial end fixed to the anterior surface of the lateral crus(Alar extension graft), (2) Inserting lateral end of the alar extension graft to the vestibular skin pocket in the form of a finger - in - groove, (3) using the vestibular skin in the form of an advancement flap, and (4) using the soft shield graft to prevent possible visible step - off of the alar margin. Results: The author applied an alar extension graft to 16 patients in order to correct a retracted ala for the last 27 months (August, 2003 - October, 2005). The distances from alar rim to long axis of nostril were improved to be within 2 mm in all of the cases, and also the shape of the alar rim changed to a round form. Nostril asymmetry (6%) in one case, temporary palpable step - off (18%) in three cases, temporary visible step - off (6%) in one case, and temporary paresthesia of the tip (25%) in four cases were observed. Conclusion: The alar extension graft is simple and efficacious. It does not need donor sites other than the operative field, and its results are predictable. In particular, since it may give structural intensity to a weak lower lateral cartilage, it may be preferentially used for the correction of a retracted ala that arises from hypoplastic lower lateral cartilage. Moreover intensified lower lateral cartilage also improves the esthetic shape of lobule.

Background: Microstomia is defined as a condition with a small sized-mouth that results in functional impairment such as difficulty with food intake, pronunciation, and poor oral hygiene and cosmetic problems. Several treatment methods for microstomia have been proposed. None of them are universally applicable. This study aims at analyzing the cases treated at our institution critically reviewing the pertinent literature. Methods: The medical records of all microstomia patients treated in our hospital from November 2015 to April 2018 were reviewed retrospectively. Of these, all patients who received surgical treatment for microstomia were included in the study and analyzed for etiology, chief complaint, surgical method, and outcomes. The functional outcomes of mouth opening and intercommissure distance before and after the surgery were evaluated. The cosmetic results were assessed according to the patients' satisfaction. Results: Five patients with microstomia were corrected. Two cases were due to scar contracture after chemical burn, two cases derived from repeated excision of skin cancer, and one patient suffered sequela of Stevens-Johnson syndrome. The following surgical methods were applied: one full-thickness skin graft on the buccal mucosa, three buccal mucosal advancement flaps after triangular excision of the mouth corner, and one local buccal mucosal flap. Mouth opening was increased by 6.0 mm, and the intercommissure distance improved by 7.2 mm on average. Follow-up was 9.6 months (range, 5-14 months). Cosmetic assessment was as follows: two patients found the results excellent, three judged it as good. Conclusion: Microstomia has several causes. In order to achieve optimal functional recovery and aesthetic improvement it is important to precisely evaluate the etiologic factors and the severity of the impairment and to carefully choose the appropriate surgical method.

Purpose: Plastic surgeons are responsible for the management of spinal cord injury patients with upper and lower extremity reconstruction, pressure sore, and wounds. Derailment of autonomic nervous systems caused by injury to the spinal cord may result in fatal autonomic dysreflexia. Autonomic dysreflexia is a syndrome of massive imbalance of reflex sympathetic discharge occurring in patients with spinal cord lesion above the splanchnic outflow(T6). It is characterized by a sudden onset and severe increase in blood pressure and is potentially life threatening. The other classic symptoms are headache, chest pain, sweating, and bradycardia. In order to lower the blood pressure, it is important to remove the noxious stimulus for autonomic dysreflexia. If such symptoms last for more than 15 minutes despite conservative interventions, antihypertension drugs are recommended. Methods: In this case study, we report an autonomic dysreflexia case that developed in a 45 year-old tetraplegia patient with sacral pressure sore. When he got bladder irrigation, his blood pressure went up very high and his mentality became stuporous. He was sent to ICU for his blood pressure and mental care. ICU care made his vital sign stabilized and his mentality alert. Results: After the patient underwent proper treatment like inotropic agent, he was transferred to the general ward and his pressure sore on sacral area was coveraged with gluteus maximus myocutaneous advancement flap. Conclusion: If treatment is not effective, the patients have to undergo sudden, severe hypertension, which can cause stroke or death. To provide safe and effective care, plastic surgeons should be able to recognize and treat autonomic dysreflexia.

Purpose: Blepharoptosis is often associated with telecanthus and the presence of epicanthal fold in telecanthus is one of unique features in Asian eyelids. The purpose of this article is to define telecanthus and pseudotelecanthus, and to determine optimal surgical procedure depending on classification of telecanthus. Methods: Among 187 patients with blepharoptosis who had the advancement procedure of the Muller's musclelevator aponeurosis composite flap for ptosis, 55 patients underwent Flowers' split V-W plasty concomitantly with shortening the medial canthal tendon for correction of telecanthus from September 2003 to January 2011. Among them, 52 patients were followed up for 16 months. We newly defined telecanthus because Mustarde ratio is inaccurate to measure in certain cases and then made a definition of pseudotelecanthus. Besides, we also classified telecanthus into mild, moderate and severe types based on its severity. Results: Telecanthus is defined when the ICD (inner canthal distance) is greater than 110% of normal ICD. Pseudotelecanthus is a telecanthus like a wide skin bridge formed between the eyes because of the epicanthal fold in the normal ICD. Flowers' split V-W plasty combined with shortening medial canthal tendon was very effective in mild and moderate telecanthus with almost invisible scar and no recurrence occurring. In severe types, however, it showed high incidence (28%) of incomplete correction of telecanthus. Conclusion: New definition of telecanthus can be easily applied to any case and we think the classification of telecanthus is useful to select an appropriate operative procedure. Split V-W plasty with shortening of medial canthal tendon is a very effective procedure in mild and moderate telecanthus. Besides, it is also effective in improving the treatment outcomes of ptosis in cases of blepharoptosis associated with telecanthus.

Purpose: The prevalence of antibiotic-resistant Streptococcus pneumoniae meningitis has increased worldwide. There are some reports about postoperative antibiotic-resistant Streptococcus pneumoniae infection after craniofacial surgery, but, there is no report in Korea. We present a report on the treatment of postoperative multidrug-resistant Streptococcus pneumoniae (MRSP) meningitis and sepsis after craniofacial surgery based on our experience. Methods: The patient was a 7-year-old boy with Crouzon's disease who was treated by fronto-orbital bar advancement. Intraoperatively, frontal sinus opening was seen during osteotomy which was covered with forehead galeopericranial flap. MRSP meningitis was diagnosed after the surgery, he was treated with intravenous vancomycin, meropenem, and levofloxacin. Results: The patient was treated successfully after 3 weeks of intravenous antibiotics treatment. During the 8 month follow-up period, there was no neurologic sequelae. Conclusion: Postoperative infection after craniofacial surgery is an important phenomenon that needs immediate recognition. Prevention, early diagnosis, and treatment immediate after onset are important as countermeasures against postoperative drug-resistant bacterial infection. To prevent adverse outcome and reoperation, proper antibiotics treatment should be performed.

Purpose: The purpose of this study was to propose a technique for periodontal biotype modification through thickening of the entire facial aspect using a volume-stable collagen matrix and autogenous subepithelial connective tissue graft (CTG) for the treatment of gingival recession. Methods: Four systemically healthy patients showing Miller class I or class II gingival recession in the mandibular incisor area were included in this study. Full-mouth scaling and root planing procedures were performed at least 4 weeks prior to periodontal plastic surgery. A split-thickness flap with a horizontal intrasulcular incision and 2 vertical incisions was used in cases 1-3, and the modified tunnel technique was used in case 4 for coronal advancement of the mucogingival complex. After the exposed root surfaces were debrided thoroughly, double-layered volume-stable collagen matrix was placed on the apical part of the recession and a subepithelial CTG harvested from the palatal area was placed on the coronal part. The amount of root coverage at 3 months postoperatively was evaluated in cases 1-3, and facio-lingual volumetric changes were analyzed in cases 1 and 2. Results: Healing was uneventful in all 4 cases and complete root coverage was shown in cases 1-3. In case 4, reduction of gingival recession was observed at 3 months after surgery. In cases 1 and 2, a comparison of stereolithographic files from the preoperative and postoperative time points demonstrated that the entire facio-lingual volume had increased. Conclusions: The surgical technique suggested herein, using a volume-stable collagen matrix and autogenous subepithelial CTG, may be an effective method for periodontal biotype modification through thickening of the entire facial aspect for the treatment of gingival recession.
