What this paper says

Across 323 primary rhinoplasties by one surgeon, each millimeter of dome lateralization produced a mean 3.6 degrees of tip rotation, allowing the final rotation angle to be estimated from the preoperative plan.

Overview

How far the tip turns upward after surgery is hard to predict, which complicates planning. This retrospective cohort study measured the relationship between a precise surgical step, moving the tip cartilage domes outward by a measured number of millimeters, and the resulting rotation angle at 6 months.

Sections of note

Retrospective analytic cohort of 323 patients operated with the new domes technique in a private clinic in Bogota, Colombia, by a single surgeon, January 1, 2011, to January 31, 2016.
Secondary rhinoplasties and patients with under 6 months of follow-up were excluded.
288 women (89.2%) and 35 men (10.8%); mean age 27.8 years, range 13 to 70.
Mean nasolabial angle: 92.7 degrees preoperatively, SD 4.4, range 77 to 107.
At 1 postoperative week: 105.5 degrees, SD 4.9, range 92 to 120.
At 6 postoperative months: 102.1 degrees, SD 4.6, range 90 to 115.
Mean rotation gained per lateralized millimeter was 3.6 degrees, SD 2.0; mean rotation at 6 months decreased by 3.4 degrees, SD 2.4, from the 1-week value. Level of evidence 4.

What it means for a patient

The tip is rotated up about 13 degrees at one week and settles back roughly 3 degrees by six months, ending about 9 degrees above where it started.
Because the surgical step is measured in millimeters, the surgeon can plan a target angle rather than judging by eye.
The standard deviation of 2.0 degrees per millimeter means individual results still vary around the average.
Limits: one surgeon, one clinic, retrospective, no comparison group, and 6 months of follow-up.

Why this paper matters

Tip rotation is among the least predictable parts of rhinoplasty and a frequent source of dissatisfaction. Tying it to a measurable intraoperative quantity makes the outcome estimable. Whether the ratio holds for other surgeons or other techniques is not tested here.

Terms

Nasal dome: The high point of each tip cartilage, forming the point of the tip.
Lateralization: Moving a structure outward, away from the midline, by a measured distance.
Tip rotation: How far the tip is turned upward.
Nasolabial angle: The angle between the base of the nose and the upper lip, used to express rotation.
Primary rhinoplasty: A patient's first nose operation.

Abstract

Importance: The postoperative changes in the rotation of the nasal tip in rhinoplasty must be estimated for the surgical planning.

Objective: To determine whether the outcome in the rotation angle of the nasal tip can be estimated in patients undergoing primary rhinoplasty with the new domes technique.

Design, Setting, And Participants: This retrospective analytic cohort study included 323 patients undergoing primary rhinoplasty with the new domes technique in a private clinic in Bogotá, Colombia, by a single surgeon from January 1, 2011, through January 31, 2016. Patients undergoing secondary rhinoplasty and those with less than 6 months of follow-up were excluded.

Exposures: Primary rhinoplasty using the new domes technique.

Main Outcomes And Measures: Measurement of the rotation angle of the nasal tip before and 1 week and 6 months after surgery. The main variable taken into consideration was the measurement, in millimeters, of the lateralized nasal domes.

Results: A total of 323 patients (288 women [89.2%] and 35 men [10.8%]; mean age, 27.8 years; age range, 13-70 years) were included in the study. The mean (SD) preoperative nasolabial angle was 92.7° (4.4°; range, 77°-107°); at 1 postoperative week, 105.5° (4.9°; range, 92°-120°); and at 6 postoperative months, 102.1° (4.6°; range, 90°-115°). The mean (SD) increase of the rotation that was achieved per lateralized millimeter was 3.6° (2.0°). The mean (SD) rotation angle at 6 months decreased to 3.4° (2.4°).

Conclusions And Relevance: The new domes technique was reliable and reproducible in most patients. Despite the unpredictable inflammatory changes, the exact lateralization in millimeters with the new domes technique allowed precise estimation of the long-term outcome of the rotation of the nasal tip, enabling the surgeon to determine from the preoperative plan the definitive rotation angle of the nose.

Level Of Evidence: 4.
