Objective:To investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group （79 patients） undergoing fistulectomy without granulation treatment, and a control group （61 patients） where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale（SBSES）. Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

Objective:To compare the clinical effect of surgical treatment of congenital preauricular fistulas in children during the local infection period and static inflammatory period. Methods:Forty children with congenital preauricular fistula infection treated in our hospital from January 2020 to December 2022 were selected as the experimental group, and 39 children with congenital preauricular fistula inflammation at static period were selected as the control group. The fistula of the two groups of children aged between 1-14 years old was located in front of the foot of the ear wheel or the foot of the ear wheel, and all were unilateral fistulas. The postoperative follow-up was 6 months to 2 years, and the efficacy of the two groups was compared. Results:There was no significant difference in the healing rate of stage Ⅰ and stage Ⅱ between the two groups（P>0.05）. There was no significant difference in fistula recurrence rate and satisfaction with the preauricular scar between the two groups after treatment（P>0.05）. There was no significant difference in postoperative hospital stay between the experimental group and the control group（P>0.05）. Conclusion:The effect of surgical treatment of congenital preauricular fistula in the infected period is similar to that of surgical treatment in the static period of inflammation, and it can reduce the pain of dressing change under local anesthesia in children, avoid the second operation in children, and reduce the economic cost. This treatment method is worthy of clinical promotion. Appropriate incision and resection method were designed according to the fistula and infection sites.

Three-dimensional (3D) printing has been particularly widely adopted in medical fields. Application of the 3D printing technique has even been extended to bio-cell printing for 3D tissue/organ development, the creation of scaffolds for tissue engineering, and actual clinical application for various medical parts. Of various medical fields, craniofacial plastic surgery is one of areas that pioneered the use of the 3D printing concept. Rapid prototype technology was introduced in the 1990s to medicine via computer-aided design, computer-aided manufacturing. To investigate the current status of 3D printing technology and its clinical application, a systematic review of the literature was conducted. In addition, the benefits and possibilities of the clinical application of 3D printing in craniofacial surgery are reviewed, based on personal experiences with more than 500 craniofacial cases conducted using 3D printing tactile prototype models.

BACKGROUND: Citation analysis is a recognized scientometric method of classifying cited articles according to the frequency of which they have been referenced. The total number of citations an article receives is considered to reflect it's significance among it's peers. METHODS: Until now, a bibliometric analysis has never been performed in the specialty of craniofacial anomalies and craniofacial surgery. This citation analysis generates an extensive list of the 50 most influential papers in this developing field. Journals specializing in craniofacial surgery, maxillofacial surgery, plastic surgery, neurosurgery, genetics and pediatrics were searched to demonstrate which articles have cultivated the specialty within the past 55 years. RESULTS: The results show an intriguing compilation of papers which outline the fundamental knowledge of craniofacial anomalies and the developments of surgical techniques to manage these patients. CONCLUSIONS: This citation analysis provides a summation of the current most popular trends in craniofacial literature. These esteemed papers aid to direct our decision making today within this specialty.

OBJECTIVE: To report a case series of Tessier 3, 4, 7 and combined 4,7 craniofacial clefts, their clinical presentations, surgical approaches and outcomes in light of the current literature.
METHODS:
Design: Case series
Setting: Tertiary Government Hospital
Subjects: Five patients
RESULTS: Five  patients aged 3 to 14-years-old with Tessier 3, 4 (2  cases), 7  and combined 4,7 were included in this study: Tessier 3 - medial orbitomaxillary cleft extending through the bony skeleton traversing obliquely across the lacrimal groove, Tessier 4 - median orbitomaxillary cleft traversing  vertically  through  the  inferior  eyelid,  infraorbital rim and  orbital  floor extending  to the lip between the philtral crest and the oral commissure  (2 cases), Tessier 7 - macrostomia and cleft oral commissure and combined Tessier 4 and 7, combining features described above. Four underwent 2- or 3-stage surgeries while one declined.
CONCLUSION: Five  craniofacial  clefts  were  presented.  Because  of  the  varying  patterns of craniofacial  deformities,  a  series of surgical  procedures,  tailor-made  for  each  individual  were performed  on  four. Otolaryngologists who perform maxillofacial and cosmetic surgery  should have good background knowledge about craniofacial defects and be familiar with the  surgical approaches at their disposal to yield favorable results that are appropriate to their local contexts.

OBJECTIVETo investigate the application of three-dimensional CT(3D-CT) in the treatment of oblique facial clefts with mandibular outer cortex, including the surgical design and results assessment.

METHODSFrom Jan. 2003 to Dec. 2013, 22 cases with oblique facial cleft, who underwent mandibular outer cortex onlay bone graft were retrospectively studied. 3D images from CT data were reconstructed before operation for design. Then the mandibular outer cortex onlay bone transplant was performed to reconstruct the bone defect and cleft. 3D CT was performed 5-10 days postoperatively and 6- 12 months postoperatively to assess the facial symmetry.

RESULTSAccording to the results of CT measurement, the average volume of the orbital bone defects on the affected side decreased by(64. 6 ± 14. 4)% 5 to 10 days after operation. The average volume of the maxillary and zygomatic bone defects on the affected side decreased by(71.4 ± 15.7)% after surgery. After 6 to 12 months,the average recovery of the mandibular donor site was (57. 9 ± 13. 9)% of the removed mandibular outer cortex. The average absorption of grafted bones was(24.7 ± 25.6 )%. The average height difference between the centre of pupils on both sides before surgery was(3.76 ± 1.27) mm,which decreased to( 1. 15 ± 1.00) mm 5 to 10 days after surgery(P =0. 000) , and( 1.35 ± 1. 13) mm 6 to 12 months after surgery(P = 0. 003). The relapse may be caused by the absorption of the grafted bones.

CONCLUSIONS3D-CT can be used for preoperative design and postoperative assessment in the treatment of oblique facial cleft with mandibular outer cortex.

OBJECTIVETo primarily assess the surgical technique to correct incomplete Tessier No. 3 craniofacial cleft.

METHODSFrom 2009 to 2010, 3 male patients with incomplete Tessier No. 3 craniofacial clefts were treated. Preoperative CT examination of each patient was performed and the bony defect was evaluated. In the operation, van der Meulen rotation and advancement flap of the cheek and regional Z-plasty were used and the medial canthal ligament was repositioned.

RESULTSOne week after the operation, the sutures were removed and the facial incision healed well. The facial scar was not obvious 6 - 10 months after operation. The shape of medial canthal angle was acceptable, and the height of the medial canthal angle and the length of the palpebral fissure of both sides were symmetrical. The clinical results were satisfactory.

CONCLUSIONSFor the incomplete Tessier No. 3 craniofacial cleft, surgical treatment is mainly focused on the deformities of inner canthus and nasal alae. Medial canthal ligament reposition is the key procedure for correction of the medial canthal deformity and surgical results are stable and reliable.

OBJECTIVETo determine the antimicrobial effects of grape seed on peri-implantitis microflora.

METHODSThe grape seed extract was tested against peri-implantitis microflora most commonly found in craniofacial implants including reference strains of Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Candida albicans (C. albicans) and clinical strains of S. aureus, Klebsiella pneumonia (K. pneumonia) and Candida parapsilosis (C. parapsilosis) by disk diffusion test. Minimum inhibitory concentrations (MIC) and minimum cidal concentrations (MCC) were determined using modified agar dilution millpore method. The extract was further combined with polyethylene glycol and propylene glycol, and was tested for antimicrobial effects.

RESULTSGrape seed extract showed positive inhibitory effects with S. aureus at MIC of 0.625 mg/mL and MCC of 1.25 mg/mL respectively. However the extracts showed minimal or no reactivity against strains of E. coli, K. pneumonia, C. parapsilosis and C. albicans. The use of grape seed extract in combination with polyethylene glycol and propylene glycol also showed dose dependent inhibitory effect on S. aureus.

CONCLUSIONSThe results of the study showed that grape seed has potential antimicrobial effects which can be further studied and developed to be used in the treatment of infected skin-abutment interface of craniofacial implants.

INTRODUCTIONAlthough uncommon, fractures of the os odontoideum are known to occur in children under 7 years old, following acute trauma.

CLINICAL PICTUREWe report a case of chronic subluxation of the os odontoideum resulting in cervical myelopathy in a child with Beare-Stevenson cutis gyrata syndrome after surgery to the head and neck.

TREATMENT AND OUTCOMEThe patient was initially put in a Halo vest, following which occipital cervical fusion was performed.

CONCLUSIONSubluxations and fractures at the odontoid synchondrosis are rare but should be anticipated in young children with risk factors for instability of the cervical spine.
