This article provides a concise description of common complications of rhinoplasty, recommendations for avoidance, and corrective techniques. The surgeon must have a comprehensive understanding of nasal anatomy and effects of surgical maneuvers to help avoid complications. Meticulous history, physical examination, and standardized photographic documentation are central to preoperative evaluation and surgical planning for rhinoplasty. Photographic documentation is useful to illustrate preexisting preoperative asymmetries. Appropriate preoperative counseling regarding appropriate postoperative expectations as well as all risks, benefits, and alternatives is critical. Any complications should be openly discussed with the patient.

Overview
Rhinoplasty is a very common surgical procedure among facial and general plastic surgeons. It may be performed for functional and aesthetic reasons. It is a highly technically challenging procedure, because the surgeon must pay careful attention to both form and function. An aesthetically pleasing nose without the ability to breathe is a surgical failure. Some complications may occur intraoperatively, whereas others may occur postoperatively during wound healing and contracture. Therefore, some complications may not become evident until months to years after surgery.

Asymmetries
Asymmetries of the bony pyramid can occur for multiple reasons, including discrepancies in osteotomies between sides, asymmetric dorsal reduction, and persistence of preoperative asymmetries. A greenstick fracture, with failure to fully osteotomize, may result in either failure to fully mobilize the nasal bone or the nasal bone lateralizing from memory.
Asymmetries of the middle third are also often multifactorial. A septal deviation that was not causing asymmetry before dorsal reduction may become “unmasked” after dorsal reduction, and thereby cause asymmetries of the middle vault. Asymmetric dorsal reduction of the middle third can also occur. Palpation of the dorsum with moistened gloves allows careful assessment of the underlying anatomy after dorsal reduction.
Establishing symmetry at the tip is highly dynamic and requires an understanding of all major and minor tip support elements, as shown in Table 1 . Careful attention to tip suture technique and proper suture placement will help minimize tip asymmetries. Preexisting asymmetries of the medial and lateral crura may not be evident until other tip dynamics are altered. Similar to the middle third, a septal deviation that was not causing any asymmetry preoperatively may become “unmasked” as a result of surgical maneuvers, with resultant tip asymmetry or deviation. Contracture of the skin soft tissue envelope can also result in asymmetry of the tip over time.

Edema of the soft tissue envelope can make asymmetries and irregularities difficult to discern intraoperatively. Thus, careful marking before injection is paramount. Asymmetries can be minimized through judicious inspection from the top of the patient’s head and through careful palpation using sterile saline-moistened gloves.
The bony pyramid
Overresection of the Nasal Bones
Overresection of the nasal bones can be avoided through judicious dorsal reduction, as seen in Fig. 1 . Notice that this patient also has a pollybeak deformity, which is discussed later. More bone may easily be removed, whereas replacement after overresection presents a more challenging scenario.
Open Roof Deformity
An open roof is a normal consequence of dorsal reduction. Failure to close an open roof with appropriate osteotomies will result in a “flat top” appearance to the bony pyramid, as seen in Fig. 2 . Edema of the soft tissue envelope can mask an open roof deformity on visual inspection. Again, careful palpation will make this readily apparent to the surgeon. Medial and lateral osteotomies are used to close an open roof deformity, narrowing the bony pyramid.
