Aims and Backgrounds Hanging alar deformity is an excessive caudal projection of the alar rim found particularly among Asians. In this review, we conducted a retrospective photographic analysis of cases underwent alar hanging correction using modified arrow tip technique. Historical Aspects Numerous techniques have been developed to address this deformity. However, these methods have their pros and cons in terms of precision and post-operative care. Patient Selection 138 patients undergoing modified arrow tip correction at a private clinic in Bangkok, Thailand during January 2022 - October 2025 was included. Techniques and Results The technique relies on a partial-thickness excision. The mean frontal height decreased from 15.15 ± 1.87 mm to 13.21 ± 1.63 mm (-11.80 ± 10.77 %). The lateral height reduced from 16.18 ± 1.93 mm to 13.88 ± 1.69 mm (-13.26 ± 9.49 %). Differences between views were statistically significant. Scarring and asymmetry were found in 10.14% and 1.45%, respectively. Current and Future Development Effectiveness in broader patient populations and the potential benefits of combining with complementary procedures should be explored in broader populations. Conclusion and Clinical Relevance Modified arrow tip technique is safe, effective, and reproducible for addressing hanging alar deformity with minimal complications.
