Microbial contamination profile change over a 4-year period in nonoperated cleft soft palate.

AIMS: Surgical site infection is a major concern in cleft soft palate. Knowledge of the type, number and antimicrobial resistance of pathogens present preoperatively contribute to treatment success. The aim of this study is to determine whether or not the microbial contamination (diversity) preoperatively has changed since 2015. METHODS AND RESULTS: Swabs were taken from the surgical site in 103 consecutive patients who presented for primary repair of the soft palate cleft. These were sent for microscopy, culture and sensitivity testing. Swabs were taken before disinfecting the site. Results were tabled and compared with two previous studies from the same facility. Out of 103 patients, 100 patients showed positive cultures with 42 different pathogenic micro-organisms identified. Most dominant pathogen was Klebsiella pneumoniae, 45.6%, increased by 28% from the previous two studies, with 93.6% of these pathogens resistant to one or more antimicrobials. Most of the other identified pathogens showed an alarming increase in occurrence, with a wide resistance to antimicrobials. CONCLUSIONS: The increase in number and diversity of microbial contamination as well as their resistance to antimicrobials is a real concern. Ways of preventing postoperative infection in a natural way need to be explored. SIGNIFICANCE: Surgeons need to be aware of constant changes in micro-organisms.

Distraction Osteogenesis in a Tessier 6 Cleft After Fronto-Orbito-Zygomatic Osteotomy - A Case Report.

The Rationale: Craniofacial clefts are rare malformations. According to their localization, 15 types are classified. Patient Concerns: They referred to impaired eyelid function, lateral protection of the eye-bulb, and aesthetic appearance. Diagnosis: A three-dimensional-computerized tomography scan and a stereolithographic model led to the diagnosis of a rare intraorbital Tessier 6 cleft. Treatment: A newly designed lateral orbital rim osteotomy, presurgically simulated on a stereolithographic model, was performed to forward position the lateral orbital rims bilaterally by osteodistraction. Outcomes: Both lateral orbital rims were distracted anteriorly for around 12 mm over a period of 9 weeks, without any side effects to the patient. Take-away Lessons: In this intraorbital Tessier 6 cleft, an improved eyelid function with better lateral protection of the eye bulb and more favorable aesthetic appearance was achieved with this novel lateral orbital rim osteotomy.

A Descriptive Study of Chlorhexidine as a Disinfectant in Cleft Palate Surgery.

OBJECTIVES: Chlorhexidine is seen as the golden standard of disinfectants. It is widely used to clean surgical sites; however, many studies indicate resistance of pathogens to chlorhexidine. One study indicated that pathogenic microorganisms were isolated from the soft palate cleft region in 57% of patients with facial clefts. The objectives of our study were to determine (1) if chlorhexidine application is effective in removing pathogens from the surgical site in these patients, and (2) if any pathogens are isolated, determine if they are resistant to other antimicrobials. DESIGN: A descriptive observational study. SETTINGS: A private practice that specializes in facial cleft surgery, with a country-wide patient base. All procedures were executed by one oral and maxillofacial surgeon. PARTICIPANTS: All patients (N=50) who presented for primary repair of the soft palate cleft were included in the study. INCLUSION CRITERIA: written consent from parent(s), and patient cleared as systemically healthy by a pediatric physician. EXCLUSION CRITERIA: patient(s) with systemic infections (eg, flu) and/or any local infections (eg, tonsillitis). There were 25 males and 25 females with an average age of 7 months and 16 days included in the study. METHODS: Swabs were taken from the surgical site of all 50 patients with cleft soft palate and were sent for culture, identification and antimicrobial sensitivity. The swabs were taken before disinfecting the site as well as after 2 minutes of disinfecting the surgical site with chlorhexidine. Results were compared against each other. RESULTS: Positive cultures with 28 different pathogenic microorganisms that were identified in 47 patients before cleaning the surgical site with the chlorhexidine. The most dominant pathogens were K. pneumonia (n=22), H. influenza (n=18) and S. aureus (n=10). Of the pathogens found, 13 (46%) were still present on the swabs taken after disinfecting with chlorhexidine. K. pneumonia (n= 13), H. influenza (n=11) and S. aureus (n=9) were still the most prevalent pathogens. CONCLUSIONS: This study demonstrated that 61 of the total of 113 pathogens isolated (54%), survived after 2 minutes of disinfecting the surgical and surrounding area with chlorhexidine, thus intensifying the chances of post-operative infection.

Fracture of the vomero-premaxillary junction in a repaired bilateral cleft lip and palate patient.

Although dental trauma is common in bilateral cleft lip and palate (BCLP), patients' reports on bony fractures of the vomero-premaxillary junction cannot be found. The aim of this report is to illustrate clinical findings and the technique of fracture fixation in a child suffering from a fractured vomero-premaxillary junction as well as subsequent columella lengthening. A 4-year-old girl with a repaired BCLP presented with an open mucosal laceration and fractured vomero-premaxillary junction. Open reduction and fixation of the dislocated premaxilla was performed under general anesthesia. Fractured bone pieces of the vomero-premaxillary junction were removed and sharp bone edges at the vomer and the premaxilla were grinded. The repositioned premaxilla was fixed to the lateral alveolar arches with two mucoperiosteal sutures on each side. Additional columella lengthening was performed 2 years later. All family members were very happy about the new aesthetics of the girl. Although rare, fractures of the vomero-premaxillary junction present several challenges to clinicians related to anatomical, physiological, and psychological issues. Immediate and minimal invasive treatment strategies are recommended when managing such cases.

Columella pressure necrosis: a method of surgical reconstruction and its long-term outcome.

Nasal continuous positive airway pressure (nCPAP) in premature babies may rarely lead to necrosis of the columella. Subsequent functional and cosmetic impairments require surgical corrections to restore nasal anatomy and architecture. The objective of this report is to document the technique of reconstruction in a baby with columella necrosis due to nCPAP treatment. A 21-month-old baby was referred to the oral and maxillofacial unit with a necrotic columella following nCPAP ventilation in a neonatal intensive care unit. Nearly 75% of the vertical columella length was affected. A neocolumella was created using tissues mobilised from the nasal sill region. This report provides a detailed description of a columella reconstruction technique which is valuable to restore aesthetics and function.

Alveolar band in patients with cleft lip and cleft alveolar deformities.

A complete cleft of the lip is often interrupted by a Simonarzt band. Very rarely, a similar fibrous soft tissue band can be seen interrupting the complete cleft of the alveolus. This alveolar band has not been previously described in the literature.

A classification and construction of congenital lateral facial clefts.

BACKGROUND: The repair of the lateral or transverse facial cleft is a surgical challenge on the account of the abnormal positioning and appearance of the cleft. MATERIALS AND METHODS: Over a twenty-seven year period, 22 lateral facial cleft cases were evaluated at a cleft lip (CL) and palate clinic and seven children underwent reconstruction of the lateral CL. RESULTS: Twenty-two of 3187 (0.69%) cases presented with a lateral CL. Five of these 22 cases (23%) had a bilateral, eight (36%) had a right-sided and nine (41%) had a left-sided cleft. The evaluation of these cases resulted in a new classification (namely an extension of the Tessier 7 cleft) classification for the cutaneous and muscle involvement: a superior (T7.1), middle (T7.2), inferior (T7.3) and agenetic (T7.4) lateral CL. The altered surgical construction: an internal mucosal straight-line closure, a curved cutaneous-mucosal red-lip/vermilion-lined flap for the lip commissure, muscle reconstruction at the modiolus and a positional cutaneous z-plasty for the rare lateral cutaneous cleft. CONCLUSION: The paper introduced a new classification for the lateral CL, as well as an altered surgical reconstructive technique for the most natural functioning of the lateral part of the face.

Construction of the congenitally missing columella in midline clefts.

BACKGROUND: Repair of the rare median cleft lip occurring with agenesis of the columella is a challenge as there is a major deficiency of skin and underlying structures. MATERIAL AND METHODS: Over a 23- year period, five children underwent construction of a columella. A new surgical technique was designed for this: an internal dorsal nasal flap was used to create a cutaneous-cartilaginous flap inside the nasal dome, and was then sutured inferiorly against a superior triangle of the repaired median cleft lip. RESULTS: Projective nasal growth could be seen in three of the five surgically constructed columellae in whom the medium-term results could be evaluated. CONCLUSION: Five holoprosencephaly cases, all with a median cleft lip and agenesis of the columella, underwent a median cleft lip repair and the creation of a columella by means of an internal nasal dorsal skin flap procedure.
