MANAGEMENT
GOALS
Closure of Cleft
Separate oral and nasal cavities. Prevent nasal regurgitation of oral contents.
Normalization of Speech
Requires competent VP mechanism
Operative goals: close cleft, reposition LVP, increase length
Prevent maladaptive compensatory misarticulations
Perform repair by 1 year of age Timing of speech milestone (first words)
Prelinguistic testing may indicate need for earlier
surgery

Hearing
Recurrent otitis media commonly occurs in patients with CP
Eustachian tube dysfunction: abnormal LVP insertion impairs “milking” action, which leads to poor venting of middle ear Permanent impairment results with recurrent infection
Myringotomy tubes often placed at time of CP repair
Some surgeons advocate for tensor tenopexy during palatoplasty to improve eustachian tube function postoperatively Restoration of velar anatomy improves eustachian tube function
Maintenance of Facial Growth
*Palate repair in early childhood may adversely affect maxillary growth, but this drawback is outweighed by the improvements in speech achieved by early correction.
Early soft palate and delayed hard palate repair has been advocated (controversial two-stage approach) by some European cleft centers to maximize midfacial growth.
Variable speech outcomes. Nearly 90% of U.S. surgeons perform single-stage repair.
*Around 25% of patients will require orthognathic surgery in adolescence (Le Fort I advancement; see
Chapter 18: Orthognathic Surgery) for midface
hypoplasia and class III malocclusion.
REPAIR TECHNIQUES
In CLP (Veau III or IV), both the primary and secondary palates require repair
The entire hard palate mucoperiosteum must be elevated for oral sided closure Nasal mucosa elevated off bony cleft margins to provide two-layer closure Vomer flaps utilized for nasal layer closure
https://t.me/medicina_free
Soft palate dissection allows for nasal, oral, and muscle repair
In isolated CP, only the secondary palate requires repair
Veau I—soft palate repair only with closure of nasal, muscle, and oral layers Veau II—soft palate repair and posterior hard palate repair that may require lateral relaxing incisions or bipedicled mucoperiosteal flaps if cleft is wide
Soft Palate Repair Techniques
Straight-line repair with intravelar veloplasty (IVV) (Fig.
14-3)
IVV first described by Kriens in 1967 Useful in wide clefts Three-layered closure (nasal mucosa, muscle, oral mucosa) Correct aberrant insertion of LVP from hard palate and rotate posteriorly into transverse orientation IVV: complete LVP dissection from nasal and oral mucosa, disinsertion from posterior hard palate, and muscle repair in the midline Adverse sequelae: potential for short palate and subsequent VPI
Furlow palatoplasty or double-opposing Z-plasty (Fig. 14-4)
https://t.me/medicina_free
Figure 14-4 Furlow double-opposing Z-plasty. The procedure is not that
different from primary cleft palate repair. Above, left: the posteriorly based oral musculomucosal flap is elevated first. The clefted levator muscle is detached from its hard palate attachment and nasal mucosa. When the lateral extent of the dissection nears the hamulus, the levator as a distinct muscle bundle coming into the flap. Above, center: The lateral limb incision is made from the base of the uvula to just lateral to the hamulus. As the flap is elevated, care is taken to
https://t.me/medicina_free
separate the mucosa from the underlying muscle. The plane should be deepened to the back of the hard palate and carefully detached from it, without damaging the greater palatine vessels. Above, right: The anteriorly based nasal mucosal flap is incised from the base of the uvula to the superior constrictor. Below, left: The posteriorly based nasal musculomucosal flap is created by incising the nasal mucosa 3 to 4 mm from the posterior edge of the hard palate toward the eustachian orifice for ~1 cm. With the tip of the flap pulled transversely, the levator muscle is released carefully from the new free margin of the nasal mucosal incision, and the lateral limb incision is extended until the tip of the flap will reach the end of the contralateral nasal mucosal flap lateral limb incision. This brings the distal end of the levator muscle against the contralateral superior constrictor and immediately under the contralateral levator. Below, center: Flaps are then inset, beginning
https://t.me/medicina_free
with the nasal musculomucosal flap, bringing the tip of the levator muscle to the contralateral superior constrictor. Below, right: The tip of the oral musculomucosal flap is positioned at the point along the lateral limb incision over the contralateral levator muscle belly, just posterior to the hamulus, orienting the levator transversely to complete the overlapping levator sling.

Opposing Z-plasty flaps for both oral and nasal closure
Posteriorly based oral myomucosal flap is on the
patient’s left
Conventional technique Remember: easier for right-handed surgeon to elevate the left-sided myomucosal triangle
first Posteriorly based nasal myomucosal flap is on the patient’s right
Rotation of triangles will “automatically” bring LVP muscles into anatomic alignment (recall: anomalous LVP insertion) Lengthens soft palate
https://t.me/medicina_free
Offsets the nasal and oral suture lines (decreasing risk for fistulas) Adverse sequelae: sacrifice of width in order to gain length; may not be possible in wide clefts (consider IVV)
Hard Palate Repair Techniques
Von Langenbeck repair (Fig. 14-3)
Bipedicled mucoperiosteal flaps
Anterior pedicle: blood supply via sphenopalatine a. Posterior pedicle: blood supply via greater palatine a.
Parallel incisions are made along cleft margin. Lateral relaxing incisions along lingual side of alveolus left open to heal secondarily. Nasal and oral mucosal flaps are mobilized to midline and sutured in two layers. Adverse sequelae: potential for maxillary growth restriction; high tension repair, which may lead to dehiscence.
V-Y pushback (Veau-Wardill-Kilner)
Unipedicled flaps V-Y advancement of mucoperiosteal flaps Lengthens palate for speech Adverse sequelae: significant potential for maxillary growth restriction
Two-flap palatoplasty (Bardach repair)
Requires elevation of entire palatal mucosa: island flap based on greater palatine a. May be used in wide cases of isolated CP to gain extra mucosa for closure Most common repair in Veau III and IV Adverse sequelae: anterior areas heal secondarily causing maxillary growth restriction
Additional Maneuvers for Wide Clefts
Infracture of the hamulus can bring lateral elements toward midline
https://t.me/medicina_free
Osteotomy of greater palatine foramen for increased pedicle length The periosteal sheath around pedicle can be released with meticulous dissection to gain additional pedicle length
ADJUNCTIVE TECHNIQUES
Buccal Fat Pad Flaps
Used to cover raw surfaces of hard palate laterally to minimize scarring and secondary growth restriction or to fill in dead space at areas of high tension (hard-soft palate junction) to decrease risk of fistula Small incision made just lateral to maxillary tuberosity Fat “teased” from buccal space with gentle spreading motion Can be spread to cover surprisingly large surface area Will mucosalize secondarily
Vomer Flaps
Based superiorly Used for nasal mucosal closure anteriorly in all Veau III/IV repairs
Facial Artery Myomucosal Flap
Intraoral mucosal flap based on facial artery. Often used to repair palatal fistulae secondarily
Gingivoperiosteoplasty
Can obviate the need for secondary bone grafting during mixed dentition May be indicated at time of lip repair to close alveolar segments Only feasible if greater and lesser segments are within 1 mm of each other
Performed frequently at cleft centers that utilize nasoalveolar molding or Latham devices

POTENTIAL COMPLICATIONS OF CP REPAIR
Acute Airway Obstruction
Bleeding/aspiration/laryngospasm. Tongue swelling due to reperfusion injury from Dingman mouth gag. Reintubation in immediate perioperative period is ~1%. Some patients require ICU admission for closer monitoring. Place tongue stitch and nasopharyngeal airway postoperatively. Pulse oximetry overnight.
Dehiscence of Palatal Flaps
Undue tension Poor flap vascularity Poor tissue handling
Palatal Fistula
Reported rates range from 5% to 50%. More common in Veau III/IV than Veau I/II.
*Hard/soft palate junction is the most common location.
Requires repair if causes nasal regurgitation of food or hypernasality.
Midfacial Growth Restriction
Intrinsic midface growth problems are present in children with CP or CLP. Scarring/secondary healing from palate repair exacerbates maxillary growth restriction. May be reduced by avoiding secondary intention healing.
Limit undermining when possible.
Use buccal fat pad flaps to close lateral open areas. Timing of palate repair: as late as possible to allow maximal growth, but before the emergence of speech.
Hyponasality: much less common than VPI; related to overaggressive closure of velopharynx
https://t.me/medicina_free
VPI (Please see Chapter 15: Velopharyngeal Insufficiency for details)
Incomplete closure of velum
Air escape through nasopharynx
Hypernasal speech
Secondary to inadequate palatal length or poor muscle
function
20% incidence following palatoplasty Patient develops maladaptive compensatory substitutions of abnormal for normal sounds in order to be
understood
Pharyngeal fricatives
Glottal stops
Treatment
Obturator (prosthesis) to fill areas of tissue deficit
Posterior pharyngeal flap (PPF)
Static, nonphysiologic technique Myomucosal flap from posterior pharynx
Mucosa and superior pharyngeal constrictor m.
Superiorly based and sutured to soft palate Appears as a tissue “bridge” with two lateral ports Requires the patient to have movement of lateral walls
Dynamic Sphincter Pharyngoplasty (DSP)
Dynamic technique
*Superiorly based myomucosal flaps from posterior tonsillar pillar flaps (palatopharyngeus m.)
Crossed and overlapped (to variable degrees) in midline Indicated with absent or minimal medial excursion of lateral walls Appears as a single port
Buccal myomucosal flaps
Myomucosal flaps elevated intraorally from buccal mucosa
