Incidence and Preoperative Risk Factors for Major Complications in Aesthetic Rhinoplasty: Analysis of 4978 Patients

Overview

Published rhinoplasty complication figures come mostly from small retrospective series. This study drew on the CosmetAssure database, a prospective multicenter record, to measure how often serious complications occur and which patient factors predict them. Major complication meant an emergency room visit, hospital admission, or reoperation within 30 days.

Sections of note

• Prospective cohort of patients operated between May 2008 and May 2013; 129,007 patients identified, of whom 4,978 (3.9%) had a rhinoplasty.
• Overall major complication rate 0.7 percent, 37 patients.
• Most common: hematoma 0.2 percent, infection 0.2 percent, pulmonary complications 0.1 percent.
• Age 40 or over was an independent risk factor, relative risk 2.05, P 0.04.
• Complications rose from 0.58 percent for rhinoplasty alone to 1.02 percent with one other body region, P below 0.05, and 2.09 percent with two other regions, P below 0.05.
• Pulmonary complication risk rose from 0.1 percent to 1 percent when two other body regions were added, P below 0.05.
• Gender, type of surgical facility, smoking status, and BMI 25 or over did not significantly affect risk. Level of evidence 2.

What it means for a patient

• Serious complications after rhinoplasty alone are uncommon, under 1 in 100 in this cohort.
• Combining rhinoplasty with other cosmetic operations roughly doubled the risk with one addition and quadrupled it with two.
• Being 40 or over doubled the risk relative to younger patients.
• Limits: only complications within 30 days requiring emergency care, admission, or reoperation are counted, so cosmetic dissatisfaction, late deformity, and revision for appearance are outside this figure.

Why this paper matters

This is one of the largest prospective datasets on rhinoplasty safety and gives numbers for the combined-procedure question patients often ask. The 30-day major-complication definition is narrow by design. It says nothing about aesthetic outcomes or long-term revision rates.

Terms

• Major complication: Here, one requiring an emergency room visit, hospital admission, or reoperation within 30 days.
• Prospective cohort: A group tracked forward in time as events occur rather than reviewed afterward.
• Hematoma: A collection of blood under the skin or tissue.
• Relative risk: How many times more likely an event is in one group than another.
• Pulmonary complication: A problem affecting the lungs or breathing, such as a clot or pneumonia.
