Evaluation of Tonsillotomy Effects on Pharyngeal Volume and Compliance in Children

Abstract: Our objective was to assess whether adenotonsillotomy improved pharyngeal compliance, which is a risk factor for sleep-disordered breathing. Otherwise healthy children underwent Obstructive Sleep Apnea (OSA)-18 questionnaire and a pre- and postoperative acoustic pharyngometry in both sitting and supine positions, allowing the measurement of the volume of the palatine tonsil region and pharyngeal compliance. Thirty-five children (median age 5.3 years) were enrolled; they were reevaluated at a median of 18 days … Show more

“…The main limitation of our present study is the absence of an experimental design adapted to demonstrate the causal link between HRV modifications and increased pharyngeal compliance, which remains to be evaluated in a prospective design. Nevertheless, we recently showed that a decrease in pharyngeal compliance was observed after adenotonsillectomy in children with increased preoperative compliance (Al Ali et al., 2020), which may be put in line with the results of Muzumdar et al . demonstrating a decrease in sympathetic and an increase in parasympathetic tones after adenotonsillectomy (Muzumdar et al., 2011).…”

“…Consequently, children with OSA (two groups) and without OSA were matched for sex, age (±1 year), z ‐score of body mass index (BMI; ±0.30) and ethnicity, as these anthropometric factors influence HRV in children (Liao, Li, Vgontzas, et al., 2010). We first described the patients according to these three groups, and with versus without OSA, and participants were subsequently divided according to normal or increased pharyngeal compliance as previously done (Al Ali et al., 2020).…”

“…The main result of this study is the relationship found between tonsillar hypertrophy and pharyngeal collapsibility. This result was suggested by a previous study of our group (Al Ali et al, 2020), but also by two studies from Marcus and colleagues (Marcus et al, 1994; Marcus et al, 2005). We hypothesise that this increased pharyngeal collapsibility in children with tonsillar hypertrophy may be related to pharyngeal muscle fatigue as a result of the upper airway muscles working against an increased load every night.…”
