“…Despite significant improvements in respiratory parameters, there was evidence of residual sleep disordered breathing in most reports. More recent trials by MARTINHO et al [186] and NAKATA et al [187] investigated patients with OSA who where either intolerant to a CPAP trial or required high CPAP pressures to treat upper airway obstruction due to tonsillar hypertrophy. Based on these reports tonsillectomy play a role similar to nasal surgery in increasing the use of CPAP in patients with tonsillar hypertrophy, or when CPAP therapy is not possible as the first choice of therapy.…”

“…As early as 1975, Koski and Lä hdemä ki 33 had suggested that dorsal rotation of the mandible in children with large tonsils was primarily a physiological response to maintain adequate pharyngeal airspace. Nasal resistance in patients with obstructive sleep apnea syndrome is reported to be higher than that of normal controls, 34,35 the nasal obstruction resulting primarily from structural abnormalities or inflammatory mucosal disease. Eliminating pharyngeal obstruction during sleep is the main focus of treating sleep-disordered breathing, but nasal obstruction can complicate treatment when oral appliances or CPAP are used.…”

Objective: To study upper airway breathing in 115 children annually from 8 to 17 years of age with the hypothesis that upper airway respiratory needs increase steadily during growth and show sexual dimorphism. Material and Methods: To calculate nasal resistance, airflow rate (mL/s) and oronasal pressures (cmH 2 O) were measured during rest breathing in a seated position using the pressure-flow technique.Results: Median values of oronasal pressure ranged at different ages in girls from 0.88 to 1.13 and in boys from 0.92 to 1.44 cmH 2 O, being 0.95 and 0.93 cmH 2 O at the age of 17 years, respectively. The gender differences were statistically significant in four age groups (P , .05 by the Mann-Whitney test). Mean values of nasal resistance decreased from 8 to 17 years of age in girls from 4.0 (63.27) to 2.4 (62.30) and in boys from 3.3 (62.48) to 1.5 (60.81) cmH 2 O/L/s. However, there was an increase in resistance in 11-year-old girls and 12-year-old boys and at the age of 15 in both genders (P , .05 by paired t-test). Conclusions: Respiratory efforts stabilize oronasal pressure to maintain vital functions at optimal level. Nasal resistance decreased with age but increased temporarily at the prepubertal and pubertal phases, in accordance with other growth and possibly hormonal changes. When measuring upper airway function for clinical purposes, especially in patients with sleep apnea, asthma, allergies, cleft palate, or maxillary expansion, the measurements need to be compared with age-and genderspecific values obtained from healthy children.

“…However, it should be noted that enlarged tonsils are associated with lower hyoid bone position, 17 and tonsillectomy leads to reduced nasal resistance. 18 Because of the possible confounding effects of adenotonsillectomy on the airway, patients who had these procedures performed during orthodontic treatment were excluded.…”

Objective: To examine changes in hyoid to mandibular plane distance (H-MP) and tongue length (TL) between children who had orthodontic treatment with and without rapid maxillary expansion (RME). Materials and Methods: Lateral and frontal cephalograms of 138 patients treated with RME and 148 controls treated without RME were used to measure pretreatment (T 1 ) and posttreatment (T 2 ) intermolar (IM) distance, lateronasal width (LNW), H-MP, and TL. Medical histories were used to collect demographic information, history of mouth breathing, difficulty breathing through the nose, and previous adenotonsillectomy. Groups were group-matched for age and gender. Descriptive statistics were calculated. Group means were compared using t-tests and chi-square statistics. Reliability was estimated using intraclass correlations and kappa statistics. Statistical significance was set at P , .05. Results: At T 1 , the RME group showed smaller LNW (24.83 6 1.99 vs 26.18 6 2.05) and IM (50.17 6 2.3 vs 51.58 6 2.83). The distance from H-MP was longer in the RME group (15.69 6 3.95 vs 13.86 6 3.4). Mean changes (T 2 2 T 1 ) in the RME group were increased LNW (+2.48 6 1.38 vs +0.94 6 1.11 for the non-RME group) and IM (+3.21 6 1.72 vs +0.98 6 1.67). The mean change (T 2

Reduced Nasal Resistance after Simple Tonsillectomy in Patients with Obstructive Sleep Apnea

Abstract: The reduction in nasal resistance induced by simple tonsillectomy could play an important role in improving OSAS, as does nasal surgery or adenotomy.
