Surgical Treatment and Reconstruction of Nasal Defects According to the Aesthetic Subunits Principles

Núñez-Castañeda, José Miguel, Chang-Grozo, Silvana Lucia 01 January 2021 (has links)

Observational cross-sectional study of all consecutive patients with the diagnosis of skin tumor located in the nasal unit, treated from 2018 to 2019 by the department of head and neck surgery of a general hospital. 60 patients were treated with nasal skin tumors excisions. A total of 52 patients (86,6%) had basal cell skin cancer, 7 (11,6%) had squamous cell skin cancer and 1 (1,6%) had melanoma. Fifty-nine patients (98.33%) presented a primary tumor and just 1 case (1,66%) recived a previous surgical treatment. Regardless of the type of tumor, the tip subunit was the most often involved with 29 (48,33%) cases in total. Despite of the nasal aesthetic subunit affected, the most frequent type of procedure used for reconstruction was the rotation or advancement flap, based on aesthetic nasal subunits, which was performed in 39 cases (65%). Nasal reconstruction after skin cancer can be very complex, especially since all patients have high expectations about the results. In order to achieve good results, there is a necessity for careful analysis of the defect, correct planning and excellent technical execution of the procedures Frequently, staged procedures will be needed to achieve an optimal result. / Revisión por pares

Facial reconstruction according to aesthetic units

Nunez Castaneda, José, Chang Grozo, Silvana 01 October 2020 (has links)
Context: The facial subunit principle organizes the facial skin into subunits. Facial reconstruction for skin cancer based on aesthetic units consists of replacing the entire subunit when a large part of a subunit has been removed. Aims: To determine the prevalence of facial skin cancer, their location by facial aesthetic units, and the type of facial reconstruction used in each of them. Settings and Design: An observational cross-sectional study was conducted at the Head and Neck Surgery Service of a general hospital between 2017 and 2018. Materials and Methods: A population census was conducted during this period. Statistical Analysis Used: The categorical variables were expressed as frequencies (percentages). Continuous variables were described as the means and standard deviations or medians and interquartile ranges. Results: The most common skin cancer was basal cell skin cancer, followed by epithelial skin cancer and, at last, melanoma. In general, the most frequent localization of these cancers was the nose. Conclusions: In spite of primary closure being the most common form of reconstruction, a considerable number of patients required facial reconstruction based on aesthetic facial units, with satisfying results. / Revisión por pares
