Indications and Technique for Open Rhinoplasty in Patients With Dorsal Hump and Wide Tip

DEFINITION
Dorsal hump refers to excess height in the upper third of the nose. When examining a patient in the lateral view, ideally the nose should be in line with a line drawn from the radix to the tip (or slightly behind this line in females); any excess projection anterior to this line is a dorsal hump.
Wide tip refers to a variety of configurations of the lower lateral cartilages that create the appearance of bulbous and poorly defined nasal tip.
ANATOMY
The anatomy of the dorsal hump is usually both cartilaginous and bony. The nasal bones and the dorsal septum can both or independently be excessive. Any of these situations can contribute to a dorsal hump.
A wide tip is primarily related to positioning and orientation of the lower lateral cartilages. Dr. Rohrich and colleagues categorized three types of boxy tip relating to a wide intercrural angle, a wide domal arch, or both.1 Wide or bulbous tips can also result from bifidity of the nasal tip, excess or convex lateral crura, or lower lateral cartilage malposition.
PATIENT HISTORY AND PHYSICAL FINDINGS
Dorsal hump and wide nasal tip are the two most commonly encountered patient complaints regarding their nose.
On palpation of the dorsum, a dorsal hump can be bony or cartilaginous, or in some instances both.
Palpation of the tip cartilages is important to give information regarding integrity, positioning, and recoil of the lower lateral cartilages.
IMAGING
Although CT imaging can be useful in nasal surgery for airway abnormalities, routine scans are not obtained for patients presenting for correction of dorsal hump and wide nasal tips.
SURGICAL MANAGEMENT
A clear surgical plan should be outlined prior to any rhinoplasty procedure.
Preoperative Planning
The patient is counseled extensively in preoperative discussion regarding surgical outcomes and recovery. Photographs are taken and will be used intraoperatively. Currently, we do not use 3D imaging software.
Positioning
The patient is in the supine position with the head slightly extended.
Approach
The open approach is used for full visualization of deformities in the dorsum and tip.
TECHNIQUES
▪ Correction of the Dorsal Hump
An inverted V or upright V incision is used to open the nose along with bilateral infracartilaginous incisions (TECH FIG 1A).Stay updated, free articles. Join our Telegram channel
