BACKGROUND: Keloids are benign fibro-proliferative lesion, related to excessive inflammatory reactions in certain anatomical areas, including the auricles. Their specific etiology remains unclear; nonetheless they exhibit tumor-like characteristics of significant recurrence and cause emotional distress, even with various treatment strategies. We applied intermittent magnetic pressure therapy on ear keloids in combination with surgical excision, and present its effectiveness herein.METHODS: Ear keloid patients were treated with surgical excision followed by magnetic pressure therapy. The keloid tissues underwent excision and keloid marginal flaps were utilized for wound closure. Intermittent magnetic pressure therapy was applied 2 weeks after the surgical procedure. The pressure therapy consisted of a 3-hour application and 2-hour resting protocol (9 hr/day), and lasted for 6 months. The results were analyzed 6 months after the therapeutic procedures, using the scar assessment scale.RESULTS: Twenty-two ear keloids from 20 patients were finally reviewed. Among the keloids that completed the therapeutic course, 20 ear keloids out of 22 in total (90.9%) were successfully eradicated. Two patients (2 keloids) exhibited slight under-correction. Postoperative complications such as wound dehiscence or surgical site infection were not noted. The scar assessment scale demonstrated a significant improvement in each index. The intermittent pressure therapy led to patient compliance, and avoided pressure-related pain and discomfort.CONCLUSION: Excision followed by intermittent pressure application using a magnet successfully reduced the burden of fibro-proliferative keloids, and had good patient compliance. The role of intermittent pressure application and resting should be studied with regard to keloid tissue remodeling.

Vertigo, dizziness, and disequilibrium are common symptoms following concussion or traumatic brain injury. Dizziness and vertigo may be the result of trauma to the peripheral vestibular system or the central nervous system, or, in some cases, may be due to anxiety, depression, or posttraumatic stress disorder; these mechanisms are not mutually exclusive. While most peripheral vestibular disorders can be identified by testing and examination, those without inner ear causes that have persisting complaints of dizziness and motion sickness are more difficult to understand and to manage. Some of these patients exhibit features compatible with vestibular migraine and may be treated successfully with migraine preventative medications. This paper reviews the neurological causes of persisting dizziness, the possible mechanisms, and the pathophysiology, as a framework for patient management and for future research.

3.Modified composite graft using diced autogenous cartilage for amputated ear reconstruction: A case report
Archives of Aesthetic Plastic Surgery 2019;25(2):65-68
Trauma to the auricle is common given its prominent position, and various methods for ear reconstruction exist. Herein, we present our experience of ear reconstruction using diced autogenous cartilage. A 72-year-old woman fell from a 1-m height, damaging her ear in the process. The ear helix, which was approximately 3.5×3 cm² in size, was amputated. The cartilage was diced into 1-mm pieces. The detached skin was made into a pocket and filled with the diced cartilage. Molding was performed with tie-over dressings on the anterior and posterior areas of the scaphoid fossa. Ten days post-surgery, the wound showed signs of successful recovery, and the contour of the ear helix was maintained. Ten months later, the cartilage in the damaged ear helix was intact. Conventional composite grafts on amputated ears have size limitations and exhibit significant resorption, and loss of anatomical structures and stability often occur. In this case, the operating time required to complete the composite graft was short, and molding the contour was not complex. The original ear structure was maintained over the long term and did not require an additional operation for aesthetic purposes. We believe that this is a useful method for the reconstruction of an amputated ear.

Although efficacies and proportions of tympanoplasty performed via endoscopic ear surgery (EES) have gradually introduced, it remains unclear whether total EES is a good alternative to microscopic ear surgery (MES). Herein, we aimed to compare therapeutic effects of EES and MES in patients receiving tympanoplasty or myringoplasty. A search of MEDLINE, PubMed, and Embase databases was conducted to compare the efficacies of EES and MES. Two investigators independently reviewed all studies and extracted data with a standardized form. We assessed risk of bias and calculated pooled odds ratio (OR) estimates with a 95% confidence interval (CI). Thirteen studies (607 EES patients and 678 MES patients) met inclusion criteria for quantitative meta-analysis. In pooled analysis, those who undergo EES have 0.99 times the OR of graft success compared to those with MES (95% CI, 0.84 to 1.16; P=0.894). In qualitative analysis, comparable hearing improvement was observed between the two groups, despite inconsistent audiometric evaluation. The air-bone gaps (ABGs) improved 2.02 dB less in EES than in MES (mean difference of improvements of ABGs, 2.02; 95% CI, –3.84 to –0.20; P=0.029); however, substantial heterogeneity and publication bias limited the integrity of this analysis. Further, EES significantly decreased canalplasty rate, wound complications, and operation time, compared to MES. Moreover, patients receiving EES reported higher cosmetic satisfaction than patients receiving MES. EES can be a good alternative to MES in terms of comparable graft success rate and hearing outcomes in patients receiving tympanoplasty or myringoplasty. Moreover, EES was less invasive, resulting in higher cosmetic satisfaction, reduced morbidity, and shorter operation time. Our results may affect decision-making and outcome prediction in cases of EES; however, confirmation is needed to clarify potential bias.

BACKGROUND AND OBJECTIVES: Temporal bone fracture (TBF) is a common occurrence in cases of head trauma. Although the incidence of temporal bone concussion (TBC) has increased in cases of head trauma, it has not been extensively studied. We assessed the characteristics of TBF and TBC in patients with head trauma. SUBJECTS AND METHODS: We conducted a retrospective review of 432 patients with head injury who visited our hospital between January 2011 and April 2016. Of these patients, 211 who met the inclusion criteria were included in the study. Their clinical characteristics, causes of injury, and hearing function were analyzed. RESULTS: Among the 211 patients, 157 had TBFs and 54 had TBCs. Ear symptoms were more common among patients with TBF than among those with TBC. Car accidents were the most common cause of both TBF and TBC, but assault and sports injuries were more common among patients with TBC than among those with TBF. The occurrence of facial palsy in both cases of TBF and TBC. Hearing loss was observed among 35 patients with TBF and 11 patients with TBC. However, patients with TBF showed conductive hearing loss with an air-bone gap. Hearing function of these patients with TBF recovered with a reduced air-bone gap, but the patients with TBC showed little recovery. CONCLUSIONS: Emergency physicians should focus more on temporal bone injury in patients with head trauma. Therefore, an early complete diagnostic battery, which includes high-resolution computed tomography, audiometric tests, neurologic examination, and vestibular tests, be performed in patients with head trauma.

6.Blast-induced hearing loss.
Journal of Zhejiang University. Science. B 2019;20(2):111-115
The incidence of blast injury has increased recently. As the ear is the organ most sensitive to blast overpressure, the most frequent injuries seen after blast exposure are those affecting the ear. Blast overpressure affecting the ear results in sensorineural hearing loss, which is untreatable and often associated with a decline in the quality of life. Here, we review recent cases of blast-induced hearing dysfunction. The tympanic membrane is particularly sensitive to blast pressure waves, since such waves exert forces mainly at air-tissue interfaces within the body. However, treatment of tympanic membrane perforation caused by blast exposure is more difficult than that caused by other etiologies. Sensorineural hearing dysfunction after blast exposure is caused mainly by stereociliary bundle disruption on the outer hair cells. Also, a reduction in the numbers of synaptic ribbons in the inner hair cells and spiral ganglion cells is associated with hidden hearing loss, which is strongly associated with tinnitus or hyperacusis.

7.Local Silencing of Connective Tissue Growth Factor by siRNA/Peptide Improves Dermal Collagen Arrangements.
Tissue Engineering and Regenerative Medicine 2018;15(6):711-719
BACKGROUND: Collagen organization within tissues has a critical role in wound regeneration. Collagen fibril diameter, arrangements and maturity between connective tissue growth factor (CTGF) small interfering RNA (siRNA) and mismatch scrambled siRNA-treated wound were compared to evaluate the efficacy of CTGF siRNA as a future implement for scar preventive medicine. METHODS: Nanocomplexes of CTGF small interfering RNA (CTGF siRNA) with cell penetrating peptides (KALA and MPGΔNLS) were formulated and their effects on CTGF downregulation, collagen fibril diameter and arrangement were investigated. Various ratios of CTGF siRNA and peptide complexes were prepared and down-regulation were evaluated by immunoblot analysis. Control and CTGF siRNA modified cells-populated collagen lattices were prepared and rates of contraction measured. Collagen organization in rabbit ear 8 mm biopsy punch wound at 1 day to 8 wks post injury time were investigated by transmission electron microscopy and histology was investigated with Olympus System and TS-Auto software. RESULTS: CTGF expression was down-regulated to 40% of control by CTGF siRNA/KALA (1:24) complexes (p < 0.01) and collagen lattice contraction was inhibited. However, down-regulated of CTGF by CTGF siRNA/MPGΔNLS complexes was not statistically significant. CTGF KALA-treated wound appeared with well formed-basket weave pattern of collagen fibrils with mean diameter of 128 ± 22 nm (n = 821). Mismatch siRNA/KALA-treated wound showed a high frequency of parallel small diameter fibrils (mean 90 ± 20 nm, n = 563). CONCLUSION: Controlling over-expression of CTGF by peptide-mediated siRNA delivery could improve the collagen orientation and tissue remodeling in full thickness rabbit ear wound.

Journal of the Korean Medical Association 2018;61(12):715-723
Facial soft tissue injury due to trauma is common. Severe damage of soft tissue causes functional and cosmetic problems. In the initial evaluation of patients with facial trauma, airway maintenance and respiratory maintenance are the most important. The principles of treatment include adequate irrigation and debridement, primary closure, or secondary wound healing. Postoperative care such as taping, silicone gel sheeting, and sun screening is important to prevent scarring. The scalp and forehead are abundant in blood and can cause severe bleeding. The eyelid is very thin and has a multi-layered structure, requiring accurate suturing and reconstruction of the layers. It is advisable to determine the presence of hematoma in the ear and treat it. When the cheek area is damaged, it is necessary to identify and treat the damage of the parotid gland and the facial nerve branch. The lips should be sewn with the white roll of lip and vermillion.

9.Clinical Features of Patients with Labyrinthine Concussion after Head Trauma.
Soonchunhyang Medical Science 2017;23(2):108-111
OBJECTIVE: Blunt head injury can lead to isolated damage of the inner ear (cochlear labyrinthine concussion) or damage of the otolith organ (vestibular labyrinthine concussion) due to a bone conduction pressure. We evaluated the clinical characteristics of hearing impairment in patients who suffered from a blunt head trauma without any organic problems, including temporal bone fracture or intracranial hemorrhage. METHODS: This retrospective study examined 9 patients presenting with hearing impairment after blunt head trauma within recent 5 years. This study included only patients without temporal bone fracture or intracranial hemorrhage. RESULTS: Most patients complained of associated auditory symptoms including tinnitus, dizziness, earfullness, and otalgia. Twelve ears of 9 patients showed sensorineural hearing loss; mild (1 ear), moderate (3 ears), moderate-severe (4 ears), severe (2 ears), and profound (2 ears). After high-dose steroid therapy, 2 ears had a significant hearing gain, but 10 ears showed no improvement of hearing. CONCLUSION: Blunt head injury is one of the most common causes of the neurologic disorders. It is important to perform thorough assessment of auditory symptoms as soon as possible. Otologic consultation should be sought in all cases for appropriate management.

10.A Novel Surgical Method Using Two Triangular Flaps for Accessory Tragus.
Hyun Ho HAN ; Hak Young KIM ; Deuk Young OH
Archives of Aesthetic Plastic Surgery 2016;22(2):63-67
BACKGROUND: Accessory tragus is an abnormal ear structure that has the shape of a nodule or a papule. The existing surgical method is very simple, wherein an elliptical incision is made around the lesion and the underlying cartilage is removed. However, this method may leave a depressed or dimpled scar and may cause chondrodermatitis. METHODS: We corrected the accessory tragus by a new method using triangular flaps, and the procedure was performed in eight patients. Out of the four triangular flaps, which were created by drawing lines that connected the left and the right sides and the superior and inferior surfaces of the accessory tragus and quartering them, two flaps that faced each other were excised. Once the cartilaginous tissue inside was verified and removed up to the base to the greatest extent possible, the remaining two triangular flaps were sutured and the remaining skin margin of the flap was trimmed. RESULTS: None of the patients had any wound problems related to the surgery, and none of them complained of chondrodermatitis up to 6 months postoperatively. No depression or dimple was observed externally up to 6 months after the operation, and the z-shaped scar, which was created by the crossing over of the triangular flaps, was not as visible as a linear scar. CONCLUSIONS: Correction of an accessory tragus by using the triangular flaps introduced in this study provides a wider operative view through a smaller incision, while preventing the formation of dimples or a depression after the operation.
