Individual and ethnic aspects of preoperative planning for posttraumatic rhinoplasty.

Szychta P, Rykała J, Kruk-Jeromin J - Eur J Plast Surg (2010)

Bottom Line: Parameters of the nasal shape in addition to gender were compared to average values of healthy Caucasian population, described before.Normal characteristics of the nose among individuals of three races from previous studies were also compared to one another.While preoperative planning is important, knowledge of the normal values of parameters characterising shape in both genders is equally important as the individual differences in relation to the whole face.

ABSTRACT
The aim of this study was to compare the aesthetic results of post traumatic rhinoplasty among Europeans with populations of healthy Caucasians described in earlier reports, and to collate correct parameters of nasal shape in healthy representatives of both sexes and various races for improvement in aesthetic results of surgery. 3-D scanning of the face was performed in 54 patients after posttraumatic septorhinoplasty. Analysis of 3D model was based on two indices of the nasal proportions and four angles of the region from 18 anthropological points. Parameters of the nasal shape in addition to gender were compared to average values of healthy Caucasian population, described before. Normal characteristics of the nose among individuals of three races from previous studies were also compared to one another. In females, mean height and width of the nose as well as length of both nostrils was smaller. Neither were there any significant differences in width of the nostrils and length of the nasal pyramid nor nasal prominence. Nasal proportions were similar in both sexes. Some of the nasal angles differed in addition to gender. Posttraumatic rhinoplasty resulted in correct shape of the nose similar to the healthy Caucasian population. The aesthetic nose differ among healthy individuals of the three races analysed. While preoperative planning is important, knowledge of the normal values of parameters characterising shape in both genders is equally important as the individual differences in relation to the whole face.

Mentions: Analysis of the 3-D model was based on 18 anthropological points, including seven which were separately determined for the left and right side of the body, such as: subalar (sbal), alar (al) as well as points characterising nostrils: anterior (na), posterior (np), lateral (nl) and medial (nm; Fig. 1). Additionally, six isolated points of the nose were marked: pronasale (prn), subnasal (sn), nasion (n), glabella (gl), labiale superius (ls) and the so-called “columellar point” (cp). Using the selected anatomical points, eight linear measurements were done: length and width for both nostrils (respectively, naR-npR, naL-npL, nlR-nmR and nlL-nmL), nasal height (n-sn), length of nasal pyramid (n-prn), nasal width (al-al) and prominence of nose (sn-prn). Linear measurements were carried out with accuracy of about 0.1 mm. The reliability of measurements using the anatomical points obtained by the 3-D scanner has already been confirmed in previous studies [7, 8].Fig. 1
