Objectives: Draw up an evaluative approach to the diagnostic contribution of nocturnal oximetry associated with a parental questionnaire in children with adenotonsillar hypertrophy (ATH).
Patients And Methods: Analysis of a parental questionnaire on sleep patterns and oximetry recording made in children with ATH. The results of the oximetry were compared to the data gathered from the questionnaire.
Results: Of the 342 children (age range, 3 months to 14 years), 209 permanent snorers, 115 occasional snorers, and 18 non-snorers were identified. The proportion of positive oximetry readings varied from 31.6 to 0% and the difference was significant between the first group and the two others (p<0.001). The data were correlated for four symptoms, including snoring and sleep apnea. The absence of snoring always gave a negative oximetry reading.
Conclusions: In cases of ATH, a negative questionnaire can predict that oximetry will not be useful and if necessary advise for a polysomnography for an exclusion diagnosis. In contrast, a positive questionnaire followed by a positive oximetry argues in favor of the polysomnography not being useful.

Introduction: Allergic rhinitis is the specific inflammation against allergen by immune defense cells on the nasal mucosa, which can lead to chronic nasal symptoms such as sneezing, itching, runny nose, and nasal congestion. It is associated with high morbidity including sinusitis, asthma, otitis media, hypertrophied inferior turbinate, and nasal polyps. Despite its complications, it remains poorly recognized and tracked.

Background/objectives: Evidence suggests nasal airflow resistance reduces after rapid maxillary expansion (RME). However, the medium-term effects of RME on upper airway (UA) airflow characteristics when normal craniofacial development is considered are still unclear. This retrospective cohort study used computer fluid dynamics (CFD) to evaluate the medium-term changes in the UA airflow (pressure and velocity) after RME in two distinct age-based cohorts.

Pediatric obstructive sleep apnea (OSA) is a prevalent yet often underdiagnosed condition affecting 1-5% of children globally, with higher prevalence in populations such as those with Down syndrome and obesity. Characterized by recurrent upper airway obstruction during sleep, OSA can lead to serious health consequences, including neurocognitive deficits, behavioral issues, and cardiovascular complications. The diagnosis is complicated by symptom overlap with conditions like Attention-Deficit/Hyperactivity Disorder (ADHD) while polysomnography (PSG) remains the gold standard for diagnosis, access to this test is limited in many regions.

Purpose: Undetected obstructive sleep apnea (OSA) in children increases the likelihood of perioperative respiratory complications. Current screening tools for OSA often lack sensitivity or are overly complex. This study aimed to develop and validate a simplified preoperative predictive model for moderate-to-severe pediatric OSA.
