Summary
Initiating feeding during mandibular distraction osteogenesis (MDO) surgery speeds up full oral feeds and shortens hospital stays for infants with micrognathia or Pierre Robin sequence (PRS). This approach enhances patient recovery and care.
Area of Science:
- Craniofacial Surgery
- Pediatric Surgery
- Otolaryngology
Background:
- Mandibular distraction osteogenesis (MDO) is a surgical procedure to correct micrognathia and Pierre Robin sequence (PRS).
- Feeding difficulties are common in patients with these conditions, impacting recovery.
- Optimal timing for initiating oral feeding post-MDO requires further investigation.
Purpose of the Study:
- To compare feeding outcomes in patients undergoing MDO.
- To assess the impact of initiating feeding during vs. after distraction.
- To determine if early feeding improves postoperative care for airway obstruction.
Main Methods:
- Retrospective chart review of 83 patients (2000-2024) at a single academic institution.
- Data collected via REDCap, analyzed using linear regression.
- Comparison of feeding milestones and hospital stay between two feeding groups.
Main Results:
- Patients fed during distraction reached full feeds significantly faster (1.4 vs. 12.8 days post-distraction completion, P=.027).
- Higher rates of achieving full feeds were observed in the early feeding group (72% vs. 42%, P=.01).
- Early feeding was associated with a shorter hospital stay (15 days shorter, P<.01).
Conclusions:
- Initiating feeding during MDO distraction accelerates achievement of full oral feeds.
- Early feeding during MDO is linked to reduced hospital length of stay.
- This strategy may enhance postoperative care for pediatric patients with micrognathia/PRS.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
46
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Timing and Consequences on Behavior
56
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...
