Background: The purpose of this study was to investigate the efficacy of the KTP/532 YAG laser to reduce nasal congestion and discharge in patients with allergic rhinitis.
Methods: Forty-eight patients with symptoms of allergic rhinitis were treated with the KTP/532 laser. All had positive skin tests for common allergens. Treatments were provided on an ambulatory basis in one to three sessions under local anesthesia with lidocaine nose spray. Outcome was determined by daily symptom reports and regular endoscopy examination and interviews for 12 months.
Results: Treatment was very well tolerated. There were no major side effects. At examination after 1 year, nasal obstruction was improved in 69% and nasal discharge in 40% of cases.
Conclusion: The KTP/532 YAG laser is effective for the treatment of nasal obstruction and discharge. Comparison with other techniques showed it to be the most effective in reducing nasal discharge. It can be done as an office procedure and does not damage the nasal mucous membrane. The KTP/532 YAG laser is effective as an additional treatment for patients refractory to medication.

Background: Acanthosis nigricans (AN) is a common chronic skin disorder clinically presents by velvety hyperpigmented lesions mainly at the flexural areas. Fractional photothermolysis has been reported to improve both pigmentary and textural changes by removing thin layers of skin with minimal thermal damage. Other options are the Q-switched (Qs) Nd:YAG (1064 nm) and Qs KTP (532 nm) lasers.

Background And Objectives: To compare the efficacy and safety of intradermal injection of tranexamic acid (TXA) versus Q switched (QS) KTP (532 nm) in the treatment of facial ephelides.
Study Design/materials And Methods: A randomized comparative split-face study included a total of 30 female patients with bilateral facial ephelides. One cheek was treated by intra-dermal TXA injections and the other was treated by QS-KTP (532 nm).

Lasers are fast becoming the vogue of dermatology ranging from ablative, nonablative, fractional photothermolysis to vascular lasers. There are a range of vascular lasers including potassium titanyl phosphate (KTP 532 nm), pulsed dye laser (PDL -595 nm), diode (810 nm), and Nd:YAG (1064 nm). PDL is a laser that emits yellow light using Rhodamine dye as it is lasing medium.

Solar lentigines are common pigmentary lesions. Q-switched lasers are effective treatment options but postinflammatory hyperpigmentation (PIH) is common in darker skin. The objective of the study is to compare the efficacy and safety in solar lentigines of Asian skin treated by Q-switched potassium titanyl phosphate (KTP) 532-nm nanosecond laser vs.

Background And Objective: Hyperpigmentation is a common concern in Asian patients. Few published studies address overall skin rejuvenation in this group using long-pulse (LP) laser to target pigmentation and stimulate dermal remodeling. The LP KTP 532-nm laser (LP 532-nm) is used primarily to remove epidermal lesions, while the LP Nd: YAG 1064-nm laser (LP 1064-nm) is used to stimulate dermal remodeling in Asian patients with varying efficacy.
