- Congenital Midline Cervical Cleft: A Variant of Tessier Number 30 Cleft Causing Micrognathia(2021) TONELLO, Cristiano; MATOS, Ines Correia Pinto de; FEITOSA, Leonardo Bezerra; PEIXOTO, Adriano Porto; ALONSO, NivaldoCongenital midline cervical cleft is a rare and generally isolated malformation of the ventral neck region with no clear etiology established. Mandibular deformities, such as micrognathia, could be considered as a consequence of a cleft cervical contracture. Complete surgical excision of the subcutaneous fibrous cord at an early age is the primary treatment modality, minimizing growth development problems on surrounding affected tissue. The aim of this study is to describe the clinical, surgical, and histological findings in a female child with congenital midline cervical cleft along with a relevant literature review. Three years follow-up after surgery exhibited satisfactory functional and cosmetic results.
- Simulation-Based Comprehensive Cleft Care Workshops: A Reproducible Model for Sustainable Education(2020) KANTAR, Rami S.; BREUGEM, Corstiaan C.; KEITH, Kristen; KASSAM, Serena; VIJAYAKUMAR, Charanya; BOW, Mikaela; ALFONSO, Allyson R.; CHAHINE, Elsa M.; GHOTMI, Lilian H.; PATEL, Krishna G.; SHETYE, Pradip R.; SANTIAGO, Pedro E.; LOSEE, Joseph E.; STEINBACHER, Derek M.; ROSSELL-PERRY, Percy; GARIB, Daniela G.; ALONSO, Nivaldo; MANN, Robert J.; PRADA-MADRID, Jose Rolando; ESENLIK, Elcin; PAMPLONA, Maria del Carmen; COLLARES, Marcus Vinicius Martins; BENNUN, Ricardo D.; KUMMER, Ann; GIUGLIANO, Carlos; PADWA, Bonnie L.; RAPOSO-AMARAL, Cassio Eduardo; TSE, Raymond; SOMMERLAD, Brian; FLORES, Roberto L.; HAMDAN, Usama S.Objective: Evaluate simulation-based comprehensive cleft care workshops as a reproducible model for education with sustained impact. Design: Cross-sectional survey-based evaluation. Setting: Simulation-based comprehensive cleft care workshop. Participants: Total of 180 participants. Interventions: Three-day simulation-based comprehensive cleft care workshop. Main Outcome Measures: Number of workshop participants stratified by specialty, satisfaction with the workshop, satisfaction with simulation-based workshops as educational tools, impact on cleft surgery procedural confidence, short-term impact on clinical practice, medium-term impact on clinical practice. Results: The workshop included 180 participants from 5 continents. The response rate was 54.5%, with participants reporting high satisfaction with all aspects of the workshop and with simulation-based workshops as educational tools. Participants reported a significant improvement in cleft lip (33.3 +/- 5.7 vs 25.7 +/- 7.6;P< .001) and palate (32.4 +/- 7.1 vs 23.7 +/- 6.6;P< .001) surgery procedural confidence following the simulation sessions. Participants also reported a positive short-term and medium-term impact on their clinical practices. Conclusion: Simulation-based comprehensive cleft care workshops are well received by participants, lead to improved cleft surgery procedural confidence, and have a sustained positive impact on participants' clinical practices. Future efforts should focus on evaluating and quantifying this perceived positive impact, as well reproducing these efforts in other areas of need.
- Patient-Perceived Barriers to Accessing Cleft Care at a Tertiary Referral Center in Sao Paulo, Brazil(2019) ISE, Ananda; MENEZES, Camila; NETO, Joao Batista; SALUJA, Saurab; AMUNDSON, Julia R.; JENNY, Hillary; MASSENBURG, Ben; CITRON, Isabelle; ALONSO, NivaldoBackground: In low- and middle-income countries, poor access to care can result in delayed surgical repair of orofacial clefts leading to poor functional outcomes. Even in Brazil, an upper middle-income country with free comprehensive cleft care, delayed repair of orofacial clefts commonly occurs. This study aims to assess patient-perceived barriers to cleft care at a referral center in Sao Paulo. Methods: A 29-item questionnaire assessing the barriers to care was administered to 101 consecutive patients (or their guardians) undergoing orofacial cleft surgery in the Plastic Surgery Department in Hospital das Clinicas, in Sao Paulo, Brazil, between February 2016 and January 2017. Results: A total of 54.4% of patients had their first surgery beyond the recommended time frame of 6 months for a cleft lip or cleft lip and palate and 18 months for a cleft palate. There was a greater proportion of isolated cleft palates in the delayed group (66.7% vs 33.3%). Almost all patients had a timely diagnosis, but delays occurred from diagnosis to repair. The mean number of barriers reported for each patient was 3.8. The most frequently cited barriers related to lack of access to care include (1) lack of hospitals available to perform the surgery (54%) and (2) lack of availability of doctors (51%). Conclusion: Delays from diagnosis to treatment result in patients receiving delayed primary repairs. The commonest patient-perceived barriers are related to a lack of access to cleft care, which may represent a lack of awareness of available services.
- Eyeball Preservation With Purse-String Conjunctival Closure for Melting Corneal Ulcer in Rare Facial Cleft(2021) TONELLO, Cristiano; PAULA, Raul G.; PAULA, Isabella P.; NUNES, Rodrigo B.; KOKITSU-NAKATA, Nancy M.; ALONSO, NivaldoRare facial clefts are characterized by facial involvement that is not restricted to the lip, palate, and alveolus as in traditional cleft lip and palate. The craniofacial skeleton and the orbital structures are frequently affected in these conditions. Exposure of the eyeball, when not early treated, puts the function and the preservation of the eye at risk. We report the case of a 2-month-old boy admitted to our service with an extensive oral-ocular cleft and exposure of the eyeball with melting corneal ulcer treated with a conjunctival closure with a purse-string suture.
