Rhinoplasty - Cleft
Considerations
Secondary cleft lip nasal deformity involves all tissue layers and depends on:
the original malformation
any interim surgery performed
growth of the nose and face
Unilateral cleft nasal deformity results from the alar base lacking skeletal support and involves a hypoplastic and malaligned orbicularis oris muscle on the cleft side
Dorsal deformity = possibly directed toward the cleft side, nasal bones usually thick and wide, hump is usually not an issue
Nasal base deformity = lateral, inferior, and posterior (L I P) positioning compared to the non-cleft side
associated abnormal nasal sill
Alar cartilage deformity = medial crus is shorter, while the lateral crus longer and more concave and inferiorly displaced or hooded compared to the non-cleft side
Septal deformity = caudal deviation to the non-cleft side, posterior septum to the cleft side
Tip deformity = usually deviated away from the cleft side, dome is wide and the tip is underprojected compared to the non-cleft side
Bilateral cleft nasal deformity results from bilateral lack of skeletal support for the alar base and involves deficiency in skin and soft tissue between the vermillion-cutaneous junction of the lip and the nasal tip
Nasal base deformity = bilateral lateral and posterior malposition
Alar cartilage deformity = shortened medial crura, while the lateral crura are longer compared to normal
Septal deformity = widened and reduplicated
Columellar deformity = shortened
Tip deformity = underprojected, broadened, and flattened
Timing
Starting at birth, before 1 month of age = pre-surgical nasoalveolar molding (PNAM) works to:
narrow the cleft gap
improve alar base symmetry in asymmetric clefts
expand the soft tissue envelope
elongate the columella
2-6 months = Primary rhinoplasty at the time of lip repair consists cartilage repositioning and suture techniques accessed via the standard lip repair incisions
close the nasal floor and sill
reposition the alar base via alotomy
reposition the alar cartilage
reposition the tip
4-6 years = Intermediate rhinoplasty for minor revisions
Improve alar cartilage positioning
Improve lateral vestibular webbing
Lengthen the columella
17-18 years in females and 19 years in males = Secondary rhinoplasty after definitive orthognathic surgery
total septal reconstruction
cartilage grafting
deformity camouflage
Procedure
Turbinate reduction
Septal deformity
Standard posterior septum graft harvest with ample L-strut
Complete mobilization of the caudal septum via open approach
Overlapping or end-to-end graft
May stabilize with extended spreader grafts
Excise associated bony spur
Secure to anterior nasal spine
Columellar deformity
Primary correction
V-Y advancement flap may serve to lengthen the columella if adequate columellar width and upper lip tissue are present
Anteriorly pedicled rectangular flap may be elevated to provide greater length
Brauer-Foerster technique: fan-shaped flaps along the medial and anterior margin of the alar rim, which can be pulled medially to increase columellar projection
Cronin procedure: simultaneous anterior bilobed flap advancement and posterior midline columellar flap advancement
For the absent columella:
Ferris-Smith procedure: FTSG is buried beneath upper lip skin and later rotated into place
Serre method: doubled FTSG is buried beneath upper lip skin and later rotated into place
Improving the ala will improve the columella
Ivy modification of the Blair procedure: medially and anteriorly rotating a laterally based nostril rim flap to lengthen the columella by repositioning the nasal ala
Dingman technique: medially rotating a columellar and alar-based flap
Alar deformity
Advance the alar cartilage anteriorly
Restoring the normal convexity to the lateral crural
using the lateral crus as a free graft and flipping the concave cartilage into a convex position
alar strut graft
alar rim graft
onlay camouflage graft
Improve the hooded or flattened lateral crus
Tajima reverse-U technique: suture the superior, or cephalic edge, of the LLC to the ULC or periosteum of the ipsilateral nasal bone (or even contralateral ULC or alar cartilage)
Reposition the dome
Thomas Rees technique: Lateral crus is severed from lateral attachment and advanced medially to be sutured to contralateral ala
Onlay or turn-over grafts using auricular cartilage
Auricular cartilage is weak but has the ideal curvature
Tip deformity
Improving the ala will improve the tip
Columellar strut graft for support
Tip graft for added symmetry and camouflage
Dorsal deformity
Flaring sutures
Spreader grafts for support and straightening
Onlay grafts - cartilage and/or bone
Osteotomies as needed
Hump reduction with caution, as needed
Vestibule deformity
Redundant skin may be used to line a stenotic nasal vestibule
Harvest a laterally or medially based sliding chondrocutaneous flap using the previous lip scar
Introduce new skin into the nasal sill with a perialar nasolabial flap to increase the relative size of the nostril, reposition the medially displaced alar base, and increase the length of the nostril sill to more accurately match the opposite side
V-Y–type tissue rearrangement, as needed for webbing
Post-op
Standard rhinoplasty wound care, precautions, follow-up
Medications
Consider antibiotics, especially if grafts or implants are performed and/or if revision surgery
Complications
High-Yield
What is the cleft Nasal base deformity? Lateral, inferior, and posterior (L I P) positioning compared to the non-cleft side
What is the cause? The pull of the orbicularis oris muscle
Which way is the caudal septum deviated? Away from the cleft side.
What is the cause? Again, the pull of the orbicularis oris muscle
