A New Approach for Diagnosis and Surveillance of Infantile Subglottic Hemangioma in the Era of Propranolol Use: A Case Series

OBJECTIVE

To report our institutional experience in diagnosing and surveilling patients with infantile subglottic hemangioma (SGH) using in-office flexible fiberoptic laryngoscopy (FFL) with video technology, without requiring operative endoscopy in the era of propranolol use.

METHODS

A retrospective case series was conducted on 4 children diagnosed with SGH between 2016 and 2022 at our institution.

RESULTS

Awake FFL with video technology provided adequate visualization of SGH lesions for diagnosis, without any complications. Serial examinations of the airway were performed in the outpatient setting and each SGH gradually regressed, with marked improvement in respiratory symptoms within 48 hours of oral propranolol initiation.

CONCLUSION

Our findings showed that in select patients, FFL with video technology can successfully identify SGH lesions without general anesthesia exposure. FFL may be used as a low-risk screening tool for propranolol therapy initiation in some patients, but operative endoscopy should remain the gold standard procedure for others. By utilizing FFL in this manner, it is possible to diagnose SGH lesions and start propranolol therapy without exposing all patients to the risks of operative endoscopy.

Demographic Risk Factors for Malnutrition in Patients With Cleft Lip and Palate

OBJECTIVES/HYPOTHESIS

Patients with cleft lip and/or palate (CLP) are at increased risk of malnutrition. Acute and chronic malnutrition have been associated with elevated risk of postsurgical wound complications, adding morbidity and cost to patients and their families. To study the association between demographic factors, including insurance type, race, and median neighborhood income (MNI), and malnutrition in patients with CLP.

STUDY DESIGN

Retrospective cohort study.

METHODS

Retrospective review was performed in patients undergoing their first cleft-related surgery at a large tertiary pediatric hospital from 2006 to 2018. Demographic data, weight and height at surgery, type of insurance, race, and primary residential address were collected. Geocoded information on MNI was generated using patient address. World Health Organization Z-scores for weight-for-age (WFA) and height-for-age (HFA) were used as proxies for acute and chronic malnutrition, respectively. Linear regression models were generated to analyze the relationship of insurance type, race, and MNI on WFA and HFA Z-scores.

RESULTS

About 313 patients met inclusion criteria. Increasing MNI predicted increasing WFA Z-score (0.05 increase in WFA per $1,000 increase, P = .047) as well as HFA Z-score (0.09 increase in HFA per $1,000 increase, P = .011). The effect of MNI was not independently modified by race for either WFA (P = .841) nor HFA (P = .404). Race and insurance type did not predict WFA or HFA.

CONCLUSIONS

Lower MNI is a significant independent risk factor for acute and chronic malnutrition in children with CLP. Combined with previous investigation linking malnutrition to surgical outcomes in this population, this offers a target area for intervention to improve patient outcomes.

Medial Sural Artery Musculocutaneous Perforator (MSAP) Flap for Reconstruction of Pharyngoesophageal Defects

We describe the use of the medial sural artery musculocutaneous perforator (MSAP) flap at our institution. It is a relatively new flap, originally described in 2001 for lower extremity defects, that has become increasingly popular for head and neck reconstruction due to its versatility, thinness, pliability, long pedicle, and particularly favorable donor site. It has been described for reconstruction of oral defects, but there is little published on its use in pharyngeal reconstruction. We suggest that the MSAP is an ideal flap for addressing defects caused by pharyngoesophageal stenosis, pharyngeal fistulas, or laryngopharyngectomies. We review 5 cases at our institution from June 2016 to November 2017.

Revascularization of AlloDerm Used during Endoscopic Skull Base Surgery

Objectives  AlloDerm is an acellular dermal matrix often used for reconstruction throughout the body. AlloDerm has been shown to undergo revascularization when used to reconstruct soft tissue such as in abdominal wall reconstruction. In this study, the authors review the literature on revascularization of AlloDerm and demonstrate the histologic findings of AlloDerm after implantation during skull base reconstruction. Study Design  Literature review and case reports. Setting  Tertiary Care Institution Participants  Patients from a tertiary care institution Main Outcome Measures  Histologic slides are evaluated and compared with nonimplanted AlloDerm. Methods  The authors review a case of explanted AlloDerm that had been used for skull base reconstruction after endoscopic skull base surgery. Results  Upon reviewing the histologic slides of explanted AlloDerm to nonimplanted AlloDerm, we demonstrate revascularization of AlloDerm when used in skull base reconstruction. Representative slides will be included. Conclusions  AlloDerm undergoes revascularization when used for skull base reconstruction.
