Babbling, vegetative function, and language development after cricotracheal resection in aphonic children

Area of Science:

• Pediatric Otolaryngology
• Speech-Language Pathology
• Developmental Pediatrics

Background:

• Children undergoing cricotracheal resection often experience aphonia and delayed speech development.
• Understanding the role of prelinguistic babbling is essential for optimizing language acquisition in this population.

Purpose of the Study:

• To investigate the significance of prelinguistic babbling in the speech and language development of children post-cricotracheal resection.
• To analyze speech development patterns in aphonic children following airway surgery.

Main Methods:

• Retrospective review of seven children who underwent cricotracheal resection.
• Analysis of pre- and postsurgical communication methods, speech therapy utilization, and voice quality.
• Data collection through speech-language pathology evaluations, clinical observations, and telephone surveys.

Main Results:

• Subjects experienced initial speech acquisition delays post-surgery, with vegetative sounds preceding voluntary control.
• All children exhibited a canonical babbling stage, often concurrent with vocalizations, before developing true speech.
• No correlation was found between preoperative sign language use and the rate of speech development.

Conclusions:

• The findings support the hypothesis that a canonical babbling stage is a necessary precursor for speech and language development.
• Babbling appears to be a universal stage in speech development, irrespective of the age of onset.
• Early intervention focusing on vocalization and babbling may be beneficial for children recovering from airway surgery.
