Current Status of Difficult Airway Information Dissemination at a Tertiary Pediatric Hospital.

OBJECTIVE: Difficult airway is one of the most common potential risk factors for increased fatality in craniofacial/plastic surgery patients. To date, there is no well-established and all-around difficult airway notification system in China, which has recently been recommended by existing guidelines to improve the care of patients with known difficult airways. This study aimed to investigate the current status of critical information communication concerning difficult airway management in our institute. METHODS: Vital information required to establish a difficult airway registry and notification system was collected through a literature review and expert suggestions. After approval by the Research Ethics Board, 3 online questionnaires were developed and sent to surgeons, anesthesiologists, and proxies of the patients. Knowledge of difficult airways, the willingness to be involved in the difficult airway notification system, and the way to disseminate the information were investigated in the 3 groups. The specific information that was disseminated, required, and available was investigated in the anesthesiologist group. RESULTS: Compared with the surgeons and anesthesiologists, significantly fewer patients knew the definition of a difficult airway and thought it was a potential risk factor. There were no significant differences in the willingness to be informed of the difficulty encountered during airway management. Significant differences were detected in the willingness and way to disseminate the airway information when the participants communicated with different groups. Significantly more patients would disseminate the information to the surgeon and significantly more surgeons would disseminate the information to the patient and the other surgeon. Significantly more anesthesiologists would disseminate the information to the patient and the other anesthesiologists. A significant difference was observed between what was expected and what was available for the anesthesiologist to retrieve the airway information of a patient with known airway difficulty. Significantly more anesthesiologists would notify only the patient of the diagnosis of a difficult airway both oral and written, whereas significantly more anesthesiologists would notify the other anesthesiologist of the specific difficulties in oral only. Most participants agreed to be involved in the difficult airway notification system despite the significantly lower percentage in the patient group (89%). CONCLUSIONS: Difficult airway information dissemination is, at the time of this writing, ineffective, which leads to a large gap between the expectation and practice of the anesthesiologist when caring for a patient with a difficult airway. Thus, a difficult airway registry and notification system should be developed, that has a solid foundation in all the participants.

Incidence of Ventriculomegaly in Patients With Craniosynostosis.

Hydrocephalus is variously associated with syndromic craniosynostosis (CS), while it is randomly encountered in nonsyndromic CS. But actually, the ventriculomegaly in CS is less described. In this study, the authors aim to establish whether ventriculomegaly is common in patients with CS, in both syndromic and nonsyndromic. Retrospective measurements of Evans index (EI) were taken from thin-section computed tomography scans of 169 preoperative CS patients to assess cerebral ventricular volume. EI >0.3 indicates ventricular enlargement. A total of 169 CS patients who underwent computed tomography scan from February 2018 to December 2021 were retrospectively evaluated, including 114 males and 55 females. The average age at diagnosis was 16 months (range: 1-103 mo). Among them, 37 with syndromic CS, including 17 ventricular megaly patients, had an EI >0.3 (46.0%), and 4 of them had intracranial hypertension and needed ventriculoperitoneal shunt treatment before cranial vault remolding. One hundred and thirty-two had nonsyndromic CS (100 single-suture CS, 32 multisuture CS), and 26 of them had an EI of 0.3 or greater (19.7%). Ventrocular megaly is common among patients with CS. Early craniotomy may stabilize ventricular dilation.

Application of 3-Dimensional White-Light Scanning to Observe the Lip and Nose Morphology of Chinese Children.

OBJECTIVE: To establish a database and study the growth and development of Chinese children's nasolabial units by 3-dimensional (3D) white-light scanning technology. MATERIALS AND METHODS: From January 2018 to January 2019, 528 patients were selected preoperatively in our hospital, without cranial or maxillofacial deformities. The patients were placed in supine positions in a state of sedation, and the authors used a 3D white-light scanner to scan the children's faces to measure the 3D morphological structure of their nasolabial areas. The results were presented with Graphpad Prism 8.0.2 to explore correlations and analyze trends. RESULTS: The selected Chinese children consisted of 356 males (67.4%) and 172 females (32.6%). All nasolabial subunits grew fastest at 0 to 2 years old and at a slower rate from 2 to 15 years old, whereas the relevant growth of different sex was similar among contemporaries. CONCLUSIONS: Three-dimensional white-light scanning can quickly and accurately gain 3D imaging of nasolabial soft tissue to build a normal morphology database. Furthermore, every nasolabial subunit grows fastest at the age of 0 to 2 years.

Partial Glossectomy Combined With Radiofrequency Ablation for Macroglossia in Beckwith-Wiedemann Syndrome.

OBJECTIVE: As the most common feature of Beckwith-Wiedemann syndrome (BWS), macroglossia may influence the quality of life, maxillofacial growth, and speech development of children. The retrospective study aimed to investigate the therapeutic effect of partial glossectomy combined with radiofrequency ablation (RFA) for macroglossia patients in BWS. METHODS: A retrospective study was conducted in BWS-derived macroglossia patients who underwent partial glossectomy combined with RFA from May 2019 to January 2021. In total, 35 patients consisting of 17 males and 18 females met the inclusion criteria and underwent surgery by the same plastic surgeon. Demographic characteristics, BWS features, operation details, preoperative and postoperative outcomes, satisfaction evaluations, and subgroup analysis were collected and assessed. RESULTS: Of the 35 patients involved, the average age at the time of surgery was 14.05±8.08 months, and the average surgery duration was 48.17±6.72 minutes. Only 1 patient suffered ventral tongue wound dehiscence, and the rest of the patients did not develop any other complications. The severity and frequency of tongue protrusion, drooling, snoring, and feeding difficulty were significantly ameliorated. The patient's parents showed satisfaction towards the overall surgery, tongue's appearance, and tongue's motor function. Tongue's height decreased from 32.09±1.16 mm before the operation to 29.29±1.33 mm after the operation. CONCLUSION: The partial glossectomy combined RFA exerts a safe, effective and viable technique to treat BWS-derived macroglossia.
