Premaxillary Repositioning in the Severe Form of Bilateral Cleft Lip and Palate

Single-Stage Posterior Vomerine Ostectomy and Primary Cheiloplasty in Patients with Bilateral Cleft Lip & Palate and Protuberant Premaxilla

OBJECTIVE

A protruded premaxilla has always been challenging to care for by cleft care professionals. This study aims to fortify the use of a single-stage premaxillary setback, with posterior vomerine ostectomy and primary cheiloplasty to achieve proper care for patients with bilateral cleft lip and palate (BCLP) and protruded premaxilla.

DESIGN

Longitudinal retrospective analysis.

SETTING

Twenty-three outreach programs to four countries (Ecuador, Lebanon, Peru, and El-Salvador) between 2016-2022.

PATIENTS/PARTICIPANTS

Sixty-five patients between the ages of 3 months and 6 years and 5 months, with BCLP and severely protruded premaxilla underwent premaxillary setback via posterior vomerine ostectomy and primary cheiloplasty. Patients with diagnosed syndromes and inaccessible vomer bone due to fused palates were excluded from the study.

INTERVENTIONS

Premaxillary setback with posterior vomerine ostectomy, bilateral gingivoperiosteoplasties (GPP), and primary cheiloplasty.

MAIN OUTCOME MEASURE(S)

Postoperative complications and aesthetic outcomes.

RESULTS

The mean age at surgery was 13.17 ± 14.1 months, with an average follow-up time of 26 ± 17 months. Patients underwent their procedures in Ecuador (72%), Peru (9%), Lebanon (8%) and El-Salvador (1%). The majority of patients were aged 1 year or less (66.7%) and were males (58.5%). All patients were operated on successfully and had good aesthetic outcomes. Only one patient developed partial necrosis.

CONCLUSION

Patients with BCLP and severe premaxillary protrusion have always carried immense social, psychological, and financial burdens, especially in outreach settings. Our described single-stage technique has proven to be safe and effective with good aesthetic results. Further follow-up after primary repair should be done to document and ensure proper facial growth and normal nasolabial maturation.

Primary vomerine osteotomy with gingivoperiosteoplasty for bilateral cleft lip and palate patients with protrusion and/or torsion of the premaxilla

In patients with bilateral cleft lip and palate (BCLP) with protrusion and/or torsion of the premaxilla, achieving a favorable outcome with adequate facial and maxillary development remains challenging. In the present study, we report a retrospective cohort of patients with complete BCLP who were treated between 2017 and 2020 at a single center in Japan. We investigated the effects and complications of primary vomerine osteotomy (PVO) with gingivoperiosteoplasty (GPP) following pre-surgical orthodontics (PSO) for premaxillary protrusion and/or torsion. For patients with residual premaxillary protrusion and/or torsion after PSO, PVO, and GPP were performed. The distances and angles of the premaxilla were measured on dental casts before PSO, on the day of PVO, after PVO, and on the day of palatoplasty after cheiloplasty. We further assessed postoperative complications. From a total of 36 patients with complete BCLP after PSO, seven patients underwent PVO with GPP. Proper positioning of the premaxilla was achieved in all seven patients. The distance between the anterior edge of the premaxilla and the anterior edge of the lateral segment and the length of the premaxillary-lateral segment on both sides continued to decrease over time. Loosening of GPP sutures occurred in two cases, although no major complications such as necrosis of the premaxilla or fistula formation occurred. Vomerine osteotomy with GPP before primary cheiloplasty is a potential treatment option in BCLP when the premaxilla still protrudes despite PSO or because PSO cannot be applied.

Repair Sequence and Management of the Premaxilla in Patients With Bilateral Cleft Lip and Palate: A Systematic Review of the Literature

BACKGROUND

Bilateral cleft lip and palate (BCLP) remains a difficult surgical problem due to the severely protruding premaxillary segment, with no consensus of optimal treatment sequence in older patients. A systematic review of the literature was performed to assess the current status of BCLP repair based on age.

METHODS

A PRISMA systematic review of the PubMed, Web of Science, and Embase databases was performed using a series of search terms related to BCLP. Studies were categorized based on the age of presentation, repair sequence, and technique.

RESULTS

The database search identified 381 articles. Of these, 72 manuscripts were ultimately included. The lip was repaired first in 1077 patients (86.0%), palate first in 161 patients (12.9%), and simultaneous lip and palate in 14 patients (1.1%). Patients less than 6 months old received lip repair first (n = 959, 98.6%), with complications of unaesthetic appearance (n = 86, 62.3%) and midface retrusion (n = 41, 34.1%) in younger patients and wound dehiscence (n = 8, 40%) in older patients. Primary lip repair was preceded by presurgical orthopedics (n = 760) or lip adhesion (n = 272) to reduce lip tension with nasoalveolar molding (n = 452, 62.9%) or the Latham device (n = 282, 37.1%). In older patients, the palate was repaired first or premaxillary setback (n = 222) was indicated in protruded premaxillae greater than 10 mm, but carried the risk of premaxilla mobility (n = 20, 37.7%) and midface retrusion (n = 10, 18.9%).

CONCLUSION

In younger patients, lip repair is performed first with preoperative orthopedics or lip adhesion. In older patients, the palate is more commonly repaired first compared with the lip; however, there is no difference in complication rate.

Anatomical Reconstruction in Bilateral Cleft Lip With Mendoza Technique

: The bilateral cleft lip (BCL) is the most severe manifestation of orofacial clefts. Multiple techniques have been described to reconstruct BCL to obtain good aesthetic and functional results with minimal complications.

OBJECTIVE

Description of surgical technique for BCL reconstruction and present the postoperative results obtained.

METHODS

Patients with BCL of the cleft lip and palate at ABC Medical Center from June 2013 to June 2017 operated with Mendoza bilateral cheiloplasty were included. The procedure includes an anatomical reconstruction of the lip with minimal resection of tissue, alignment of the orbicularis muscle, vestibule creation, and complete use of the prolabium. The evaluation was carried out by photographs analyzing parameters of quality, symmetry, and alignment of lip and nose structures.

RESULTS

The authors included 36 patients, 15 women and 16 men. The average procedure time was 57 minutes. Photographs were evaluated 1 year postoperatively, symmetry in lip was observed in 91.6% of the patients, muscle continuity in 100%, deep gingivolabial sulcus in 94.5% of cases, closed nasal floor in 100% with no presence of nasovestibular fistulas.

CONCLUSIONS

This technique allows an anatomical BCL reconstruction with good aesthetic and functional results.

Impact of Virtual Planning on Surgical Reposition of the Premaxilla Using an Endonasal Approach and Simultaneous Alveoloplasty

OBJECTIVE

Describe the surgical repositioning of the premaxilla using an innovative minimally invasive endonasal approach and secondary bone graft at the same time. We want to emphasize the importance of virtual surgical planning in this technique.

MATERIAL AND METHODS

A total of 6 patients with bilateral complete cleft lip and palate underwent a surgical repositioning of the premaxilla. Virtual surgical planning was performed in all cases. The ages varied between 8 and 12 years and all were male. Five patients were in the mixed dentition phase and 1 patient was in the definitive phase. Three of the patients had been prepared with presurgical nasoalveolar molding. The other 3 were not prepared for various reasons. All patients had primary repair of cleft lip and palate.

INTERVENTIONS

An innovative minimally invasive endonasal approach is presented that has allowed a safe 3-D reposition of the premaxilla in patients with bilateral cleft palate. A simultaneous secondary alveoloplasty with the use of absorbable osteosynthesis is a good choice to achieve symmetry and stability.

CONCLUSIONS

Virtual surgical planning is an exceptional instrument to make an appropriate presurgical selection of the patients in which combine the 2 procedures.

Does a Premaxillary Setback and Lip Adhesion Have a Negative Impact on Lip Outcome in Bilateral Cleft Patients?

BACKGROUND

The early premaxillary setback and lip adhesion remains as a controversial maneuver in the treatment of bilateral cleft lip and palate patients. This study aimed to assess extent of preoperative deformity and lip outcomes during the first year after surgery in bilateral cleft patients who underwent premaxillary setback and lip adhesion and to compare to those with primary lip repair.

METHODS

A retrospective observational study was conducted of 16 nonsyndromic consecutive bilateral complete cleft lip patients (with and without Simonart band), who underwent primary cleft lip repair. Patients were allocated in group 1 without premaxillary setback and group 2 with premaxillary setback and lip adhesion. Preoperative and postoperative linear measurements were used for intergroup and intragroup comparisons.

RESULTS

Cutaneous lip height of patients in group 2 significantly (P < 0.05) improved after combined premaxillary setback and lip adhesion and primary cleft lip repair. There were no significant (all P > 0.05) differences in intragroup 1 comparisons, and in intergroup comparisons.

CONCLUSION

Bilateral cleft patients with a protruded and deviated premaxilla over 10 mm discrepancy of the lateral maxillary achieved noninferior lip symmetry 1 year postoperatively compared with patients with less severe original deformity.
