Objective. Keratosis pilaris (KP) is a common condition which can frequently be cosmetically disturbing. Topical treatments can be used with limited efficacy. The objective of this study is to evaluate the effectiveness and safety of fractional carbon dioxide (CO2) laser for the treatment of KP.Patients and Methods. A prospective, randomized, single-blinded, intraindividual comparative study was conducted on adult patients with KP. A single session of fractional CO2laser was performed to one side of arm whereas the contralateral side served as control. Patients were scheduled for follow-up at 4 and 12 weeks after treatment. Clinical improvement was graded subjectively by blinded dermatologists. Patients rated treatment satisfaction at the end of the study.Results. Twenty patients completed the study. All patients stated that the laser treatment improved KP lesions. At 12-week follow-up, 30% of lesions on the laser-treated side had moderate to good improvement according to physicians’ global assessment (p=0.02). Keratotic papules and hyperpigmentation appeared to respond better than the erythematous component. Four patients with Fitzpatrick skin type V developed transient pigmentary alteration.Conclusions. Fractional CO2laser treatment may be offered to patients with KP. Dark-skinned patients should be treated with special caution.

Congenital Teratoma

<p class="abstract">Teratomas are embryonal neoplasm arises from totipotent germ cells. They are having tissues from all the three blastodermic layers. There are various locations of congenital teratoma. Naso-oropharyngeal site teratoma are either sessile or pedunculated. We describe a rare case of laryngeal teratoma in a five years old patient presented with change in voice and breathing difficulty. On flexible laryngoscopy, it appeared like supraglottic cyst but on CT scan it was confirmed as teratoma. Pre-operative tracheostomy and transoral carbon dioxide laser assisted excision done. Histopathological examination showed osteoid trabeculae, chondroid tissue with loose myxoid islands and adipose tissue. No recurrence of tumor on 18 months follow-up. This is the first case report of pediatric larynx teratoma reported in present century.</p>

Laser Excision

Inflammatory myofibroblastic tumor (IMT) is a benign neoplasm of intermediate biologic potential. It rarely occurs in the larynx, and it has not been previously reported in the epiglottis. We treated a 66-year-old woman who presented with progressive dysphonia and a mass on her suprahyoid epiglottis. The tumor was completely excised with a CO2 laser; no adjuvant therapy was administered. Histopathology revealed that the mass was an IMT. No evidence of recurrence was noted after 6 months of follow-up. We present what we believe is the first case of an epiglottic IMT to be reported in the literature, and we propose CO2 laser excision without adjuvant therapy as an acceptable treatment.

Nasal Function

A carbon dioxide laser (CO2 laser) was used to treat the hypertrophic inferior turbinates of 121 patients with nasal symptoms related to house dust allergy. Follow-up ranged from 6 to 48 months (mean follow-up period: 17.8 months). Treatment involved 10–14 watts of a defocused pulse beam of a CO2 laser fitted with special handpieces. Subjectively, 111 of the 121 patients (91.7%) reported a reduction in nasal stuffiness, 76 of the 112 patients (67.9%) had reduction in rhinorrhea, and 63 of the 96 patients (65.7%) had decrease in sneezing. Nasal airflow resistances were confirmed to have decreased in 82 patients using rhinomanometry. Nasal provocation reactions by a house dust disk, which were investigated in 10 patients, showed a tendency to reduce from 1 to 11 months after laser treatment. Nasal mucociliary transports, which were followed by the saccharin test in 50 patients, recovered 1–1.5 months after the laser surgery. To study mucosal structure after laser irradiation, the inferior turbinates of five patients were examined under a light microscope. The ciliated epithelium was shown to have recovered on light microscopic examination, whereas the number of goblet cells decreased. A net of new collagen fibers was observed in the superficial submucosa a few months after treatment. The quantity of submucosal glands was reduced in the treated portion. Such findings suggested that CO2 laser turbinate surgery may be effective in relieving the nasal symptoms associated with allergy.

Background. A consistent treatment has not been proposed for treatment of Striae Alba (SA). The present study was designed to compare the fractionated microneedle radiofrequency (FMR) alone and in combination with fractional carbon dioxide laser (FMR + CO2) in the treatment of SA.Methods. Forty-eight pairs of SA from six patients were selected. Right or left SAs were randomly assigned to one of the treatment groups. The surface area of the SA before and after treatment and clinical improvement using a four-point scale were measured at the baseline, after one and three months.Results. The mean age of the patients was30.17±5.19years. The mean difference of the surface area between pre- and posttreatment in the FMR + CO2group was significantly higher than that in the FMR group (p=0.003). Clinical improvement scales showed significantly higher improvement in the FMR + CO2group than in the FMR group in the first and second follow-up (p=0.002and 0.004, resp.). There were no major persistence side-effects in both groups.Conclusions. The results showed that FMR + CO2laser was more effective than FMR alone in the treatment of SA.

Recent Method

AbstractLateralization of one or both vocal folds is a generally accepted surgical principle for the relief of the airway obstruction caused by bilateral vocal fold paralysis. A modified, entirely endoscopic method of lateralization has been developed, employing a carbon dioxide laser to reduce the bulk of the fold, and fibrin glue to maintain the lateral position. The results of 18 operations on 15 patients, including six who had unsatisfactory results after previous surgery, were analyzed and compared retrospectively with the results from 22 patients operated on before the introduction of the method. The patient's ability to perform everyday activities improved in 12 cases, which paralleled the results of the previous, more cumbersome methods. The incidence of re-operation was comparable, given the shorter follow-up after the more recent method.
