Nasal outcomes of presurgical nasal molding in complete unilateral cleft lip and palate

Use it or Lose it: Predictors of Compliance and Satisfaction With Postoperative Nasal Stent Therapy After Primary Cleft Lip Repair

OBJECTIVE

Postoperative nasal stents (NSs) are used to improve esthetic outcomes after primary or secondary cleft lip repair (CLR). Prior studies have utilized anthropometric measurements or physician assessment to determine the efficacy of NS, but data on caregiver-reported outcomes is limited. This study aims to assess caregiver compliance and satisfaction with postoperative NS.

METHODS

The authors designed a survey to collect parent-reported postoperative NS usage outcomes. Parents of infants with cleft lip (CL) who used postoperative NS after primary CLR were approached through social media to complete the survey. Data were analyzed to determine factors impacting compliance, satisfaction, and parent-reported outcomes.

RESULTS

Eighty-five parents completed the questionnaire, and 60% reported noncompliance with NS. Parents with male children (odds ratio: 5.08, P = 0.019) and patients with incomplete CL (odds ratio: 5.72, P = 0.006) were more likely to be non-compliant with NS for over a week. Complete CL and use of presurgical molding therapy were each associated with better overall experience with postoperative NS ( P = 0.002 and P = 0.037), higher appearance ratings ( P = 0.005 and P = 0.0008), and greater satisfaction with nostril shape after surgery ( P = 0.016 and P = 0.001).

CONCLUSIONS

Despite limited literature related to caregiver-reported outcomes after postoperative NS for primary CLR, the authors' results align with what has been published regarding this topic. These results can help guide surgeons in counseling patients preoperatively. Larger, multi-institutional studies are needed to better delineate and address factors associated with compliance and satisfaction after NS therapy.

Longitudinal Anatomic Analysis of Primary Cleft Lip Rhinoplasty Outcomes

Background: The unilateral cleft lip deformity is associated with nasal deformities with secondary functional and aesthetic challenges. Objectives: Compare the change in nasal symmetry before and incrementally after primary endonasal cleft rhinoplasty concurrent with lip repair. Methods: This is a retrospective chart review of infants undergoing unilateral cleft lip repair. Data collection included demographics, surgical history, and pre- and postoperative alar and nostril photographs analyzed with Image J. Statistical analysis was done using linear and multivariable mixed effect models. Results: Twenty-two patients with a near even gender distribution (46% female) and primarily left-sided cleft lips underwent unilateral lip repair at a mean age of 3.9 months (median 3.0, range 2-12). Mean pre- and postoperative alar symmetry ratios were 0.099 (standard error [SE] 0.0019) and -0.0012 (SE 0.0179), with zero representing perfect symmetry and negative values indicating overcorrection. These values at 1, 2-4, 5-7, 8-12, 13-24, and 25+ months were 0.026, 0.050, 0.046, 0.052, 0.049, and 0.052 (SE range: 0.0015-0.0096), respectively, demonstrating stability of the alar symmetry 4 months postrepair. Conclusions: In this study, patients who underwent an overcorrective primary cleft rhinoplasty concurrent with lip repair had an initial regression of symmetry within the first 4 months postoperatively, followed by observed stabilization.

Efficacy of Post-Surgical Nostril Retainer (PSNR) in patients with UCLP Treated with Pre-Surgical NasoAlveolar Molding (NAM) and Primary Cheiloplasty-Rhinoplasty

OBJECTIVE

The aim of this investigation is to determine if the nasal form of patients with unilateral cleft lip and palate (UCLP) treated with pre-surgical nasoalveolar molding (NAM) therapy, primary lip-nose surgery, and post-surgical Nostril Retainer (PSNR) is different from patients treated with pre-surgical NAM and primary lip and nose surgery alone.

DESIGN

A cross-sectional, retrospective review of 50 consecutive non-syndromic patients with UCLP: 24 treated with NAM and primary lip-nose surgery followed by PSNR (Group I) compared to 26 patients treated with NAM and primary lip-nose surgery without PSNR (Group II). Polyvinyl siloxane nasal impressions were performed at the average age of 12 months and 6 days. Bilateral measurements of alar width at maximum convexity, total alar base width, nasal tip projection, columella length, and nostril aperture width and height were recorded. Statistical comparison of cleft versus non-cleft side nasal measurements were performed within Group I and Group II, as well as comparison of the difference between the two groups.

RESULTS

Cleft side nasal dimension was statistically significantly better in Group I than Group II across all measures except nasal projection (P<0.05). Group I showed less difference between the cleft and non-cleft side in all six measurements than Group II (p<0.05).

CONCLUSION

There is a significant difference in the nasal shape of patients who underwent PSNR compared to those that did not. The patients who used PSNR showed better nasal shape at the average age of 12 months than the control group.

Alar Lifting Technique for the Correction of Tilted Alar Base

BACKGROUND

Frequently, a tilted alar base characterized by a discrepant level of the nostril sill and alar insertion on both sides is encountered in patients seeking rhinoplasty. Herein, we report our surgical technique and outcome of alar lifting technique for correcting tilted alar base.

METHODS

The medical records of 18 patients with alar base asymmetry who underwent rhinoplasty using the alar lift technique between January 2014 and December 2019 were retrospectively reviewed. The alar lifting procedure included a pointed ellipse-shaped excision of vestibular skin just inside the nostril sill, and sutures using 5-0 monocryl. Surgical outcomes were determined on the frontal view of facial images by comparing pre- and postoperative angles formed by a line drawn parallel to the lowermost part of both pupils and a line connecting the lowermost part of the base of the ala.

RESULTS

Of 18 patients, 12 (66.7%) were men, and 6 (33.3%) were women. The mean age was 31.8 years (range 16-55). The alar lifting technique was performed on the left side in 12 cases and on the right side in 6 cases, and concurrent tip plasty was performed in 15 (83.3%) cases. The mean alar tilt angle was 3.9 preoperatively and 2.0 postoperatively. The mean angle change was 1.9°. Sixteen (88.9%) out of 18 patients had decreased alar level discrepancy. No patient had complications.

CONCLUSIONS

Our alar lifting technique can serve as a useful adjunctive technique in rhinoplasty in patients with a tilted ala.

The Effectiveness of Preoperative Correction Techniques in Improving Nasal Deformity in Children With Unilateral Complete Cleft Lip and Palate

OBJECTIVE

Unilateral complete cleft lip and palate (UCCLP) is associated with apparent nasal deformities before the cheilorrhaphy. The aim of this study was to determine whether preoperative correction techniques are effective in the treatment of nasal deformities in infant with unilateral UCCLP used by the systematic review and meta-analysis.

METHODS

We searched Medline, Cochrane Library, EMBASE, PubMed, and Chinese BioMedical Literature Database (CBM) until January 31, 2019, to identify studies that compared the effectiveness of preoperative correction techniques in the treatment of nasal deformities in infant with UCCLP. Two authors individually extracted the data and performed the quality assessments. The height of nasal columella, the width of the affected side nasal ala and the inclination of the nasal columella were evaluated.

RESULTS

Seven articles were incorporated into the systematic review, and 5 (274 participants) in the meta-analysis according to the inclusion criteria. The preoperative correction could increase the height of nasal columella in children with UCCLP [SMD: 2.64 mm; 95% confidence intervals (CI); (1.35 mm, 3.94 mm); P < 0.0001]. Moreover, the preoperative correction resulted in reduced width of the affected side nasal ala [SMD: -5.14 mm; 95% CI; (-8.96 mm, -1.31 mm); P = 0.008]; However, the evidence was insufficient to determine a significant effect on the inclination of the nasal columella [SMD: -3.48 degrees; 95% CI; (-7.56 degrees, 0.59 degrees); P = 0.09].

CONCLUSIONS

Preoperative correction for children with UCCLP can increase the height of nasal columella, reduce the width of the affected side nasal ala, improve the nasal symmetry, and reduce nasal deformity, however, no significant effect could be observed for the inclination of the nasal columella.

Comparative Study of Presurgical Infant Orthopedics by Modified Grayson Method and Dynacleft With Nasal Elevators in Patients With Unilateral Cleft Lip and Palate-A Clinical Prospective Study

OBJECTIVE

To compare the effects of presurgical infant orthopedics using 2 different methods, that is, the Dynacleft with Nasal elevator system versus the modified Grayson's technique in patients with complete unilateral cleft lip and palate.

DESIGN

Prospective comparative cohort study.

MATERIALS AND METHODS

Twenty-eight patients were divided into 2 groups, that is, Group A consisting of 14 patients who underwent correction with DynaCleft with Nasal elevator system and Group B consisting of 14 patients undergoing correction using the modified Grayson technique. Maxillary cast measurements were taken at 2-time intervals (pre- and posttreatment) to assess various parameters using a laser scanning machine (C500 Solutionix) and 3D software (GOM Inspect). Similarly, standardized anterior-posterior and worm's-eye view photographs using a custom box were taken and imported to Adobe Photoshop CS6 for measurements. Paired t test and independent t test were used to compare intra- and intergroup changes, respectively.

RESULTS

The analysis of cast (primary outcome) and photographic (secondary outcome) measurements showed improved nasal asymmetry and alveolar correction in both groups which showed no significant intergroup difference when assessed using the independent t test (P > .05). Group A showed higher chances (42.8%) of causing a T-shaped defect (due to excessive mesial-inward rotation of the minor segment) when compared to the Group B possibly due to a more controlled molding vector (P < .05).

CONCLUSION

Both methods proved effective in improving the nasal asymmetry, reducing the alveolar cleft gap, and approximating the lips together; but care must be taken when applying the alveolar molding vector in the Dynacleft system.

Clinical Outcomes Utilizing a "Modified Latham" Appliance for Presurgical Infant Orthopedics in Patients With Unilateral Complete Cleft Lip and Palate

Presurgical infant orthopedic manipulation is utilized prior to cleft lip/nasal repair to facilitate a gingivoperiosteoplasty (GPP) and primary nasolabial repairs. The Latham dentomaxillary advancement appliance uses a screw that must be tightened daily to approximate the cleft segments in unilateral complete clefts. Our cleft center has been utilizing a "modified Latham" appliance since 1987, including an orthodontic elastic power chain to close the gap in a shorter amount of time. We performed a retrospective chart review of all patients undergoing treatment at Johns Hopkins All Children's Hospital (JHACH) with a unilateral complete cleft lip and palate between 1987 and 2017. Patients were identified by the International Classification of Diseases, Ninth Revision code (749.21). The majority of the patients represent the experience of the senior authors (E.R. and R.F.). Two hundred and eighty-one patients with unilateral complete cleft lip/palate were identified. Seventy-five patients were treated with a "modified Latham" appliance prior to their lip repair. The "modified Latham" appliance remained in place on average 20.6 days (range: 4-82), and average hospital stay after placement was 1.18 days. Nearly 96% of patients underwent a successful GPP at the time of nasolabial repair. Modification of the Latham appliance by utilizing an elastic power chain and eliminating the screw allows rapid closure of the alveolar cleft with limited need for adjustments and outpatient visits. Direct approximation of the palatal segments allows successful completion of a GPP in 95.9% of patients with limited dissection.

A semi-automated virtual workflow solution for the design and production of intraoral molding plates using additive manufacturing: the first clinical results of a pilot-study

Computer-aided design and computer-aided manufacturing (CAD/CAM) technology has been implemented in the treatment of cleft lip and palates (CLP) by several research groups. This pilot study presents a technique that combines intraoral molding with a semi-automated plate generation and 3D-printing. The clinical results of two intraoral molding approaches are compared. This is the first clinical investigation of semi-automated intraoral molding. Our study included newborns with unilateral CLP. Plaster models were digitalized and measured by two independent observers. Two methods of CAD/CAM-assisted intraoral molding were compared: (i) stepwise manual design of molding plates (conventional CAD/CAM-intraoral molding) and (ii) a semi-automated approach with an automated detection of alveolar ridges (called RapidNAM) assisted by a graphical user interface (GUI). Both approaches significantly narrowed the clefts and resulted in a harmonic alveolar crest alignment. The GUI was easy to use and generated intraoral molding devices within minutes. The presented design solution is an efficient technical refinement with good clinical results. The semi-automated plate generation with a feasible GUI is fast but allows individual adaptations. This promising technique might facilitate and foster the more widespread use of CAD/CAM-technology in intraoral molding therapy.

Presurgical nasal moulding in a neonate with cleft lip

The concept of presurgical nasoalveolar moulding (PNM) was developed to improve the aesthetic result of surgically corrected cleft lip. This paper presents the method of fabrication of PNM appliance and the case of a 30-day-old neonate with unilateral cleft lip in whom nasal moulding was performed. Treatment was initiated at 30 days and continued for 60 days after which the surgical correction of cleft lip was performed. Significant improvement in aesthetics and symmetry of the nose was achieved at the end of the treatment.
