Abstrakt:	Background: Lentigo maligna is an in situ form of cutaneous melanoma that commonly arises on the head and neck. Various surgical and nonsurgical treatment options are available but no randomized trials exist to guide practice. Objective: To determine the current treatment practices for lentigo maligna of the head and neck in Ontario, Canada. Materials and Methods: Cross-sectional survey of dermatologists, plastic surgeons, and head and neck surgeons. Results: The response rate was 35% (190/542). Wide excision with immediate reconstruction was the most commonly recommended treatment for tumors on the cheek (69%), whereas staged excision with margin control was recommended most often for tumors on the nasal ala (60%). Overall, 5 mm was the most frequently recommended initial surgical margin (69%); 26.5% of respondents recommended margins wider than 5 mm. For tumors on the nasal ala, eyelid, and ear helix, more than 30% of respondents recommended an initial margin narrower than 5 mm. Conclusion: Although surgical excision is the predominant treatment modality for lentigo maligna on the head and neck, practices vary considerably in terms of the type of excision and the initial margin used. Potential response bias and the geographic restriction of our sample may limit the generalizability of our results.
