A secondary cleft lip nasal deformity can be corrected by many procedures including central lip tissue transfer, forked flap, nasal floor and alar base advancement, nasal skin flaps and composite graft. These procedures have been applied for many years, but each one has some conspicuous residual problems. We propose triple V-Y advancement flaps, which we have performed on 13 secondary cleft lip and nasal deformity patients over the past 6 years. The W-shaped triple reverse V-shaped incision easily exposed the alar cartilages. We made the advancement and rotation of the nasal skin flap to lengthen the columella and project the nasal tip. Postoperatively, the columella length and nasolabial angle were found to be increased by an average of 3.7 mm and 42 degrees, respectively. In lateral view, a relatively natural nasal line was achieved. The scar in the nasal tip posed few problems. This procedure should be useful for the correction of the secondary cleft lip nasal deformity.

Hypertrophic scarring is common in burn patients. The treatment of such scarring is difficult, and recurrence of the hypertrophic change after scar revision is not uncommon. It has been done intramarginal excision to diminish the chances of recurrent hypertrophic scarring. Core scars in the auricle are easily separated from auricular cartilage and overlying soft tissue because there is loose areolar tissue between them. We therefore reviewed our experience with core extirpation of post-burn hypertrophic scars in the auricle. Between June 14, 1991, and August 6, 1994, we excised 10 hypertrophic scars in the auricle in 5 burn patients. Core extirpations of hypertrophic scars were performed under local anesthesia with longitudinal incision along long axis of scars. The wounds were closed directly in one layer after marginal trimming. We observed that core extirpation yielded good results in post-burn hypertrophic scars in the auricles.

Vestibular neurectomy is known as an effective procedure in the management of intractable peripheral vertigo from Meniere's disease and other episodic peripheral vertigo disorders. Various approaches have been developed for selectively sectioning the vestibular nerve, in order to preserve hearing and avoid facial nerve injury. Vestibular neurectomy is performed in two patients with Meniere's disease to control intractable episodic vertigo through retrolabyrinthine approach. Vertigo was improved with preserving their hearing. We report the surgical technique and advantages of retrolabyrinthine vestibular neurectomy in the treatment of vertigo.

Sudden sensorineural hearing loss (SSNHL) is defined as acute hearing loss of >30 dB at three consecutive frequencies, with an abrupt onset (within 3 days). In most patients with SSNHL, an exact cause is rarely identified. Diverse etiological theories have been proposed, including vascular disease, viral infection, autoimmune disease, inner ear hydrops, and genetic factors. Based on these hypotheses, various treatments have been tried, including corticosteroids (systemic and/or intratympanic), antivirals, vasoactive drugs, and hyperbaric oxygen therapy (HBOT), but the evidence remains inconclusive. The 2019 American Academy of Otolaryngology-Head and Neck Surgery guideline had suggested that HBOT can be provided as either initial or salvage treatment when combined with steroid therapy. HBOT, a noninvasive treatment involving the inhalation of 100% oxygen at a pressure of >1 atmosphere absolute (ATA) is another treatment option as a method to improve oxygen supply after cochlear damage. Although the pressure, frequency, and total time of HBOT remain variable among different studies, a protocol of 2.0-2.5 ATA and 10-20 sessions in total are commonly used. The treatment strategies for SSNHL have been evolving, and recent attempts involved increasing the effectiveness through various combinations of systemic steroid, intratympanic steroid, and HBOT. In this review, we will review various studies about HBOT and discuss the efficacy of HBOT in SSNHL.

BACKGROUND: Peak expiratory flow (PEF) provides a simple, quantitative, and reproducible measure of the existence and severity of airflow obstructions. Peak flow meters are designed to monitor the condition asthma patients. There are many reports showing the normal predicted value of PEF in other countries. studies on healthy Korean adults have been performed in a relatively small sample number and a lower limit for the normal value was not reported. therefore, an attempt to provide normal predictive PEF value with a lower limit was made. METHOD: The PEF(Mini-Wright peak Flow Meter) measurements and spirometry were done in 233 men and 631 woman without history of respiratory disease. all subjects were non-smokers with no respiratory symptoms. the normal predictive value and its lower limit were developed by multiple regression analysis. The result was compared with regression equations in other reports. RESULTS: The regression equation for the normal PEF predictive value(L/min) is 25.117+4.587×Age(year)-0.064×Age2+2.931×Height(cm) in men in men(R2=0.25), and 146.942-0.011×Age2+1.795×Height(cm)+0.836×Weight (kg) in women(R2=0.21). The regression equation for the lower limit of this value (L/min) is 25.117+4.587×Age(year)-0.064×Age2+1.936×Height (cm) in men, and 146.942-0.011×Age2+1.232× Height (cm)+0.481×Weight (kg) in women. The residuals were normally distributed. The PEF in Korean males was similar to those reported in British and Japanese subjects. The PEF in Korean females was similar to that in British subjects, But higher than the PEF in Japanese subjects. The lower limit of normal value was 71% of normal predictive PEF value in men and 76% in women. CONCLUSION: The normal predictive PEF value and its lower limit was measured from 233 male and 631 female asymptomatic, lifelong non-smoking participants. The normal predictive value was different from those of other studies on Korean subjects. Therefore, further studies are required.
