RESUMEN
OBJECTIVE: To consider the clinical anatomy, safety and effectiveness of the suprazygomatic maxillary nerve block in cleft palate surgery. DESIGN: Observational case series. SETTING: Single cleft centre in the United Kingdom. PARTICIPANTS: Patients born with a cleft palate (with or without a cleft lip) undergoing palatal surgery between the ages of 9 months and 18 years. INTERVENTION: Introduction of suprazygomatic maxillary nerve (SZMN) block using ropivacaine 0.2% into clinical protocol in February 2023. MAIN OUTCOME MEASURES: Peri-procedure complications and post-operative opioid administration. RESULTS: The clinical anatomy of the SZMN block is described in a stepwise and pictorial approach from superficial to deep structures. 43 patients underwent surgical interventions involving the palate (either intravelar veloplasty, Furlow palatoplasty or bilateral myomucosal buccinator flaps for palatal lengthening). 22 patients had a general anaesthetic and local anaesthetic infiltration and 21 had an additional SZMN block. There were no local or systemic complications associated with the SZMN block. There was no difference in the total dosing of post-operative (P = .79) opioids between the groups. CONCLUSIONS: We demonstrate the feasibility and safety of this procedure without the use of ultrasound guidance in a heterogenous group of paediatric patients undergoing palatal surgery. Regional anaesthesia should be considered as part of the multi-modal analgesic strategy, although it may be difficult to demonstrate a change in opioid use in clinical settings where enhanced recovery techniques are established, and opioid use is already low.
RESUMEN
INTRODUCTION: The use of throat packs during oropharyngeal surgery has long been a topic of debate among cleft surgeons. The advantage of inserting an absorbent tulle within the pharynx must be weighed against the risk of unintended retention postoperatively. Despite safety check mechanisms in place, retention may occur with potentially life-threatening consequences. We present a comprehensive review of throat pack use in all cleft units within the United Kingdom and Ireland. METHODS: All 20 cleft surgery units in the United Kingdom and Ireland were surveyed on their use of throat packs in children aged 6 months to 2 years undergoing elective cleft palate surgery. RESULTS: The response rate to the survey was 100%. Seventy-five percent of units currently use throat packs; in 40%, they are used in addition to cuffed endotracheal tubes (ETTs). Inclusion of the throat pack in the surgical swab count was perceived as the safest mechanism employed to avoid retention. 26.1% of respondents were aware of at least 1 incident of pack retention in their unit. DISCUSSION/CONCLUSION: The reported UK and Irish experience demonstrates that three-quarters of units routinely use packs. Notably, a quarter of respondents to the survey have experience of an incident of throat pack retention. Nevertheless, the majority of respondents considered the perceived risk of retaining a pack to be low. The growing use of microcuffed ETTs in UK cleft units paired with a low incidence of perioperative complications when a throat pack is not introduced might prompt cleft surgeons to review routine pharyngeal packing.
