Granulomatous inflammation is a rare but known filler-related complication that may present similarly to an active infectious process with pain, swelling, and erythema. This study describes hyaluronic acid filler-related delayed-onset nodule formation in a pair of 44-year-old and 56-year-old females who were ineffectively treated with numerous attempts of antibiotic regimens, incision and drainage (I&D) procedures, and low-dose hyaluronidase across several months despite multiple negative microbial cultures. After initiation of hyaluronidase therapy dosed to filler-related vascular occlusion guidelines, complete resolution of symptoms was achieved in both patients. These cases emphasize the relevance of considering delayed-onset nodules in the differential for filler complications that are culture-negative and unresponsive to antibiotic treatment and I&D. We propose complete dissolution with higher dosage hyaluronidase as a safe and effective treatment modality with respect to the current lack of defined guidelines for treating this complication.

ABSTRACT Background Medial sural artery perforator (MSAP) flaps are favored in head and neck reconstruction for skin paddle pliability, pedicle length, and low donor site morbidity. We sought to characterize MSA vascular branching patterns based on the Dusseldorp et al. classification system using pre‐operative lower extremity computed tomography angiogram (CTA). Methods We conducted a retrospective review of 153 scans from 78 patients who underwent CTA prior to head and neck reconstruction at our institution. Primary data points included MSA branching pattern, branch dominance, and vessel depth. Results The type IIa branching type was most prevalent and the MSA lateral branch most frequently dominant, and they were significantly related to one another. There was no significant difference in depth between branching patterns. Conclusions Lower extremity CTA provides valuable insight to vascular anatomy for MSAP flap harvest. The type IIa and IIb types may be associated with lateral and medial MSA dominance, respectively.

Objectives/Hypothesis: Botulinum neurotoxin type-A (BoNT-A) injection into the true vocal cords is an effective treatment for restoring vocal functionality in adductor spasmodic dysphonia (AdSD). The Glasgow Benefit Inventory was developed to measure quality of life change following any otolaryngologic intervention and was recently revised to a 5-factor subdomain (GBI-5F) questionnaire to improve clinical utility. The study aim was to utilize the GBI-5F to measure patient-reported quality of life change in AdSD patients following BoNT-A injection. Methods: The GBI-5F questionnaire was administered to patients diagnosed with AdSD who received a BoNT-A vocal cord injection between December 2022 and May 2023. All patients had received multiple prior injections. GBI-5F subdomains and demographics were analyzed to identify areas for patient-reported improvement. Results: Sixty-six patients completed the GBI-5F. There were 52 (78.7%) females and average age was 69.4 years. The median total benefit score was +40.0 (interquartile range [IQR], 20.0). Median subdomain scores were +83.3 (IQR, 50.0) for quality of life, +50.0 (IQR, 50.0) for self-confidence, +33.3 (IQR, 33.3) for social involvement, +16.7 (IQR, 50.0) for support, and 0.0 (IQR, 16.7) for general health. Differences in the individual subdomain scores were statistically significant ( P < .0001). No significant differences were found in the total GBI-5F score or any subdomain according to sex or presence of vocal tremor (all P > .05). A moderately positive correlation was noted between median total score and percent functional improvement (r = 0.46, P < .001). Conclusion: Botulinum injection therapy for AdSD provides overall benefit to patients as measured by the GBI-5F, with particular improvement observed for perceived quality of life, self-confidence, and social involvement. Sex, presence/absence of vocal tremor, and age do not appear to modify benefit, though degree of functional improvement is positively correlated with total score.

ABSTRACTNoonan syndrome (NS) is a predominantly autosomal dominant condition with various cardiac and extra‐cardiac manifestations. Although it has been linked with atrial arrhythmias, ventricular arrhythmias are extremely rare in the absence of underlying structural cardiac abnormalities. We report an instance of aborted sudden cardiac arrest in a 7‐year‐old male with a confirmed SOS1 variant and a lack of evidence to support a structural cardiac, metabolic, or infectious etiology. This is the second reported instance of sudden cardiac arrest related to ventricular fibrillation in a child with SOS1‐related NS in the absence of any structural cardiac defects. Although no definitive correlation can be ascertained from a limited existing body of knowledge surrounding SOS1 and ventricular fibrillation unrelated to structural heart defects, it provokes the idea of an arrhythmia phenotype and future research is warranted to guide proper clinical treatment, monitoring, and management of such individuals.
