Clinical bottom line
Pediatric laryngeal papillomatosis remains a challenging condition characterized by recurrent benign papillomas causing airway obstruction and voice disturbances. Recent advancements in surgical techniques, notably transoral robotic excision, combined with evolving airway management strategies, offer promising improvements in disease control and patient safety. However, the disease’s recurrent nature necessitates ongoing surveillance and multidisciplinary care. Current evidence supports cautious adoption of novel surgical modalities alongside established approaches, with individualized airway management critical for optimizing outcomes.
What the evidence shows
Laryngeal papillomatosis in children is caused primarily by human papillomavirus (HPV) types 6 and 11, leading to recurrent papillomatous growths predominantly affecting the vocal cords and airway (Prentice et al., 2013). The disease often presents with progressive hoarseness, stridor, and in severe cases, airway obstruction requiring urgent intervention (Nuhut et al., 2024).
Surgical removal remains the mainstay of treatment, aiming to maintain airway patency and preserve voice quality. Traditional approaches include microlaryngoscopic excision with cold instruments or laser ablation. However, Tan et al. (2018) described the use of the Flex® Robotic System for transoral robotic excision of laryngeal papillomas, demonstrating enhanced visualization and precision in resection. This novel approach may reduce operative time and improve access to challenging anatomical sites, though data remain limited to small case series.
Airway management during surgery is critical due to the risk of airway obstruction and bleeding. LI Shao-Qing et al. (2010) highlighted the importance of tailored anesthesia and ventilation strategies in pediatric patients undergoing suspension laryngoscopic surgery for severe obstruction. Techniques such as the use of double-lumen central venous catheters have been revisited to facilitate ventilation and surgical access simultaneously (Butler et al., 2015). Rao et al. (2018) further emphasized multidisciplinary planning involving anesthesiologists and otolaryngologists to optimize perioperative safety.
Imaging, including thoracic imaging modalities, assists in assessing disease extent and monitoring for distal airway involvement (Thoracic Imaging, 2010). Despite surgical advances, recurrence is common, necessitating repeated interventions and close follow-up (Saunders et al., 2018). Adjunctive therapies such as antiviral agents or immunomodulators remain investigational and are not yet standard of care.
Caveats and uncertainty
Most evidence on novel surgical techniques like transoral robotic excision derives from small case series or single-center experiences, limiting generalizability. Long-term outcomes, including recurrence rates and voice function preservation, require further study (Tan et al., 2018). The optimal timing and frequency of surgical interventions remain individualized, with no consensus guidelines addressing these parameters comprehensively.
Airway management strategies vary widely depending on disease severity and institutional expertise. While techniques such as double-lumen catheters show promise, their use is not universally established and may carry risks in smaller pediatric airways (Butler et al., 2015). The balance between adequate ventilation and surgical exposure demands careful multidisciplinary coordination.
The role of adjunctive medical therapies remains unclear, and no high-quality randomized trials have definitively established their efficacy or safety profiles. Additionally, the potential impact of HPV vaccination on disease incidence and progression in pediatric populations is an area of ongoing research but not yet reflected in current management paradigms.
How this may change practice
Clinicians managing pediatric laryngeal papillomatosis should consider emerging surgical modalities such as transoral robotic excision as adjuncts to traditional techniques, particularly in anatomically challenging cases. Incorporating advanced airway management strategies tailored to individual patient anatomy and disease severity can enhance perioperative safety.
Multidisciplinary collaboration between otolaryngologists, anesthesiologists, and radiologists is essential for optimizing outcomes, from preoperative assessment to postoperative surveillance. Given the recurrent nature of the disease, establishing structured follow-up protocols is critical.
While awaiting more robust evidence, clinicians should remain cautious in adopting novel interventions, balancing potential benefits with procedural risks. Continued participation in registries and clinical studies will be important to refine management strategies and improve long-term outcomes for this challenging pediatric condition.
