1.Immunogenicity of botulinum toxin
Archives of Plastic Surgery 2022;49(1):12-18
Botulinum toxin treatment is the most common non-surgical cosmetic treatment. Although there are many available treatments using botulinum toxin, their effects are temporary and repeated injections are required. These frequent injections can trigger an immunological response. In addition, botulinum toxin acts as an antigen in the body; thus, its effect disappears progressively due to this immunological reaction, which may cause treatment failure. Active botulinum toxin consists of a core neurotoxin and complexing proteins, the exact effects of which remain unclear. However, the complexing proteins are closely related to the immune response and the formation of neutralizing antibodies. Since neutralizing antibodies can lead to treatment failure, their formation should be prevented. Furthermore, various methods of detecting neutralizing antibodies have been used to predict treatment failure.

White-eyed blowout fractures with extraocular muscle (EOM) entrapment necessitate emergency surgical intervention. However, even after surgery, diplopia or EOM motion limitations may persist due to the incomplete reduction of soft tissue herniation caused by inadequate dissection or unresolved muscle strangulation. In this report, we present a case of postoperative EOM movement limitation in a 5-year-old girl who experienced recurrent restriction in the upward gaze of her right eye 14 days after surgery. Instead of revision surgery, the patient was treated with targeted EOM exercises focusing on the inferior rectus muscle and inferior oblique muscle. The patient was instructed to slowly move her pupils from the central point to the upper and outer sides, then in a straight line from the central point to the lower and inner sides before returning to the center point. On the 28th postoperative day, 2 weeks after initiating the exercises, the patient’s EOM motion fully recovered. This case highlights the effectiveness of EOM exercises as a non-surgical treatment approach for improving recurrent EOM movement limitations in the absence of soft tissue herniation following surgical management of blowout fractures in children.
3.Oroantral fistula after a zygomaticomaxillary complex fracture
Archives of Craniofacial Surgery 2019;20(3):212-216
Zygomaticomaxillary complex (ZMC) fractures account for a substantial proportion of trauma cases. The most frequent complications of maxillofacial fracture treatment are infections and soft tissue flap dehiscence. Postoperative infections nearly always resolve in response to oral antibiotics and local wound care. However, a significant infection can cause a permanent fistula. A 52-year-old man visited our clinic to treat an oroantral fistula (OAF), which was a late complication of a ZMC fracture. Postoperatively, the oral suture site dehisced, exposing the absorbable plate. However, he did not seek treatment. After 5 years, an OAF formed with a 2.0× 2.0 cm bony defect on the left maxilla. We completely excised the OAF, harvested a piece of corticocancellous bone from the iliac crest, inserted the harvested bone into the defect, and covered the soft tissue defect with a buccal mucosal transposition flap. Although it is necessary to excise OAFs, the failure rate is higher for large OAFs (> 5 mm in diameter) because of the extensive defect in the underlying bone that supports the overlying flap. Inappropriate management of postoperative wounds after a ZMC fracture can lead to disastrous outcomes, as in this case. Therefore, proper postoperative treatment and follow-up are essential.

BACKGROUND: Filler injection into the soft tissue of the nose is a useful technique for rhinoplasty. The individual characteristics of fillers determine which is best suited for a patient's specific circumstances. The objective of this study was to identify the characteristics of various fillers and to determine which fillers should be used for primary rhinoplasty in order to yield optimal long-term results. METHODS: Excluding patients treated with hyaluronic acid fillers, we reviewed 17 patients who underwent surgical rhinoplasty due to dissatisfaction with an injection using a different filler. After removing the previously injected filler, rhinoplasty was performed as part of the same procedure using a silicone or Surgiform® prosthesis. RESULTS: Various previous fillers were used in the cohort. During the process of filler removal, skin perforation occurred in 2 cases and infection was observed in 1 case. In the other cases, rhinoplasty using a prosthesis was performed at the time of filler removal and no complications were observed. CONCLUSIONS: We found that if surrounding tissue had been maintained stably, a simultaneous secondary operation using implants produced ideal results in most cases without any complications, despite the presence of residual remnant filler material.

Archives of Aesthetic Plastic Surgery 2023;29(3):161-164
Scars are still a challenging problem in medical practice, despite advancements in treatment modalities. Numerous treatment modalities, ranging from simple revision, Z-plasty, and W-plasty to laser treatments, have been used to treat scar deformities. However, for wide depressed scars, additional methods are needed to completely restore the contour of the depression caused by tissue adhesion. We report on the case of a 34-year-old woman with a wide depressed scar deformity on the left upper buttock and the encouraging results of an autologous fat graft injection technique that utilized a cutting wire to form a pocket for the fat graft site, while simultaneously resolving the adhesion caused by the tissue. This method is safe and easily reproducible, making it a useful addition to the surgeon’s toolkit when dealing with such lesions.

BACKGROUND: In efforts to solve blepharochalasis, induced by aging process, various surgical methods have been developed over the years. Among them, classical upper blepharoplasty has a problem that severe lateral hooding may be restricted in making correction, cause of difference in thickness between the pretarsal skin and subbrow skin. And also subbrow excision (SE) blepharoplasty cannot be easily corrected in severe drooping of the medial skin. In an effort to make up for the disadvantages of these methods, we attempted SE-tadpole shaped excision blepharoplasty (TSEB). METHODS: Fifteen patients underwent SE-TSEB from January 2013 to November 2014. SE-TSEB was performed the following cases: 1) patients who showed moderate to severe blepharochasis with severe lateral wrinkles; 2) patients with a history of pre-existent SE blepharoplasty; 3) patients with a tattoo on the eyebrows, who want to make revision; and 4) patients with eyelid skins that are thick or have overly protuberant fat pads of the retro-orbicularis oculi fat (ROOF), and have a plan to extirpate them. RESULTS: During the follow-up observation period, most patients showed amicable correction of visibility difficulty and were aesthetically satisfied with the postoperative results with respect to correction of the lateral wrinkles. Scars formed in the subbrow incision line were within the scope of management. CONCLUSIONS: SE-TSEB is a treatment modality that overcomes the disadvantages and limitations of classical upper blepharoplasty and SE blepharoplasty. Furthermore, maximizing the advantage of each surgical approach is another innovative approach for correction of changes in the upper eyelid, induced by aging.

Depression of facial contour after parotidectomy is still challenging to many of surgeons. A 68-year-old man presented with a 4-month history of a painless swelling in both parotid area. The mass was multiple and fixed at the parotid region. We conducted a parotid duct preserving bilateral superficial parotidectomy by one-stage operation to remove the multiple tumors. A lazy S incision was made in both preauricular area and the peripheral branches of the facial nerve were identified using surgical landmark. After dissecting the branches of the facial nerve and parotid duct, main parotid duct was preserved but only small fine ductules from the superficial lobe were ligated. Parotid gland was excised from its anterior aspect with about 1 cm of normal parotid tissue margin. The patient was followed up for 6 years to evaluate postoperative parotid gland function and the computed tomography (CT) was taken. Patient was satisfied with no significant complication such as sunken changes in facial contour, facial nerve function. As far as we know, it is the first study to compare long-term soft tissue contours of soft tissue of duct preserving superficial parotidectomy with duct sacrificing superficial parotidectomy by means of CT findings.

PURPOSE: Computed tomography theoretically should improve detection of foreign bodies and provide more information of adjacent soft tissues. And the CT scanner and PACS program proved to be an excellent instrument for detection and localization of most facial foreign bodies above certain minimum levels of detectability. The severity of injury in penetrating trauma to the face, it is often underestimated by physical examination. Diagnosis of a retained foreign object is always critical. METHODS: From March, 2005 to February 2008 a study was done with 200 patients who had facial trauma. Axial and coronal CT images were obtained with a General Electric(Milwaukee, Wis) 9800 CT scanner at 130kV, 90mA, with a 2-mm section thickness and a 512x512 matrix. RESULTS: Axial and coronal CT images at various window widths should be used as the first imaging modality to detect facial foreign bodies. The attenuation coefficients for the metallic and nonmetallic foreign bodies ranged from -437 to +3071 HU. As a general rule, metallic foreign bodies produced more Hounsfield artifacts than nonmetallic foreign bodies, thus providing a clue to their composition. All of the metallic foreign bodies were represented by a single peak and had a maximum attenuation coefficient of +3071 HU. Of the nonmetallic foreign bodies, glass had an attenuation coefficient that ranged from +105 to +2039, while plastic had a much lower coefficient that ranged from -62 to -35. wood had the lowest range of attenuation coefficients: -491 to -437. CONCLUSION: The PACS program allows one to distinguish metallic from nonmetallic foreign bodies and to individually identify the specific composition of many nonmetallic foreign bodies. This program does not, however, allow identification of the specific composition of a metallic foreign body. We recommend this type of software program for CT scanning of any patient with an injury to the face in which a foreign body is suspected.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 2008;35(4):407-412
PURPOSE: Hydrofluoric acid(HF) is one of the most dangerous mineral acids with the dissociated fluoride ions. The initial corrosive burn is caused by free hydrogen ion, and the second and more severe burn is caused by penetration of fluoride ions into subcutaneous tissues. Silver is a cation producing dressing, an effective antimicrobial agent, but older silver-containing formulations are rapidly inactivated by wound environment, requiring frequent replenishment. But, Acticoat(R) is a relatively new form of silver dressing which helps avoid the problems of earlier agents. The aim of this study is to evaluate effects of Acticoat(R), silver-containing dressing on the treatment for HF injury wound. METHODS: From september 2006 to september 2007, the study was carried out with 10 patients who had HF partial thickness burns. Acticoat(R) dressing and 10% calcium gluconate wet gauze dressings in 10 cases. As a principle, in the emergency treatment, partial or complete removal of the nail and early bullectomy along with copious washing with normal saline was done, depending on the degree of HF invasion of the wound. Wound was dressed with Acticoat(R) and 10% calcium gluconate solution. The effect of dressing was investgated by serial bacterial culture and wound exudates assessment. RESULTS: We therefore reviewed 10 cases of HF- induced chemical burns and treatment principle. The 10 cases who came to the hospital nearly immediately after the injury healed completely without sequelae. CONCLUSION: As the industrial sector develops, the use of HF is increasing more and more, leading to increased incidences of HF-induced chemical burns. The education of patients regarding this subject should be empathized accordingly. In conclusion, Acticoat(R) dressing is a better choice for HF partial thickness burn injuries because of shorter healing time, less pain and more comfortable dressing.

Facial rejuvenation using Botulinum toxin A is one of the most popular aesthetic procedures. Many cosmetic applications of Botulinum toxin A are under evaluation. Intradermal injection of Botulinum toxin A is a variation of the intramuscular injection technique and remains relatively new technique. This evaluates the effects of intradermal injection of Botulinum Toxin A on facial wrinkle lines. Thirty patients were included to undergo intradermal injections of Botulinum toxin A on forehead, cheek and periorbital area. Three sessions of injection were performed for 10 days. Clinical photograpahs were taken for 24 weeks, and evaluated patient's satisfaction and objective improvement of facial wrinkle lines. Improvement in patient's satisfaction and facial wrinkle line was noted in the post-treatment photographs. This effect was lasted for about 12 weeks. The intradermal injection of Botulinum toxin A is effective method for facial rejuvenation without obvious side effects.
