Between 1913 and 1985, 323 cases of infantile subglottic hemangiomas have been reported in the English language literature. The purpose of this study is to review these cases, to report The Johns Hopkins Hospital experience with ten additional cases, and to compare the various methods of treatment in an attempt to identify the regimens associated with the best outcome. The majority of the patients presented before the age of 6 months with respiratory distress, most commonly inspiratory stridor. There was a 2:1 female to male preponderance. The diagnosis was established by endoscopy in the majority and confirmed by biopsy in one third, without serious bleeding complications. A plethora of treatment methods have been described, including the following: corticosteroids, tracheotomy, radiation therapy, radioactive implant therapy, surgical excision, cryotherapy, and carbon dioxide laser. These methods were reviewed and their results compared to our own. We conclude that several methods are effective, each having its advantages and disadvantages. We believe that immediate tracheotomy should be performed in cases with severe airway obstruction. Smaller lesions may be vaporized with the carbon dioxide laser without tracheotomy if postoperative care is provided in a pediatric intensive care unit. Corticosteroids may be used alone or in combination with other modalities. External radiation therapy and injection of sclerosing agents are not advised.

Introduction Dysphonia is caused by voice misuse and various environmental factors. It is   manifested as varied pathological lesions of the vocal cords. Surgical excision of these lesions is mainly by conventional cold steel or laser assisted microsurgical techniques. Both modalities have seen extensive advancements and refinement in technologies in the recent past. In this study we have compared the microdissection microlaryngeal treatment and microspot superpulsed beam carbon dioxide (CO2) laser assisted surgical techniques for the management of benign and precancerous lesions of the vocal cords. Material and Methods A total of 36 cases of benign lesions of vocal cord, were divided randomly to undergo surgery either by microdissection or CO2laser assisted techniques. The groups were assessed through vocal cord morphological observation and subjective voice assessment parameters GRBAS score and VHI10 index. Results Peroperative bleeding was observed to be significantly reduced in the laser excision group.  However, operating time was significantly increased in this group. Patients recovered remarkably well following both the techniques as denoted by voice parameters. No difference was observed in duration of hospital stay.  Conclusion Both surgical techniques give satisfactory results in their management of benign and precancerous lesions of the vocal cords. Both techniques have their advantages and disadvantages. After a learning curve, laser surgery with its precision and cleaner surgical fields will be more effective in the management of such cases.

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.
