Deviated Nose: A Systematic Approach for Correction
Autor: Ahmed M. Abu El-Wafa, MD, Sherif S. Emara, MD
Publikováno v: Plastic and Reconstructive Surgery, Global Open, Vol 8, Iss 8, p e3078 (2020)
Background:. Attaining a straight dorsum in patients with deviated nose is a main task in rhinoplasty. The basis of this difficulty is the presence of multiple anatomical abnormalities; hence, many methods are used to correct such a deformity. In thi
