RESUMEN
Background: To compare efficacy of continuous positive airway pressure (CPAP) and oral appliance (OA) in management of various grades of obstructive sleep apnea (OSA). Methods: Thirty polysomnography diagnosed cases of OSA were divided into three groups based on baseline apnea hypopnea index (AHI) as follows: group 1: mild OSA (AHI = 5-14.9), group 2: moderate OSA (AHI = 15-29.9), and group 3: severe OSA (AHI >30) with 10 patients in each group. Half of the patients in each group were randomly allocated to CPAP or OA therapy, and crossover of therapy was performed after two months. AHI, Epworth's Sleepiness Scale (ESS), and mean oxygen saturation (SPO2) were measured at baseline, after each arm of treatment and after the crossover. A questionnaire survey including information regarding pretreatment sleep symptoms and improvement after therapy was performed at above time frames. At the end of therapy, the patients were surveyed regarding satisfaction and perceived effectiveness with both modalities. Results: CPAP was more efficacious in reducing AHI and SPO2 as compared with OA across the three study groups. The improvement in most sleep-related symptoms was higher with CPAP. The satisfaction and perception on effectiveness of treatment were higher with OA than CPAP across three study groups (P-value<0.05 for all). Conclusions: OA is an effective alternative to CPAP across all grades of OSA in selected cases, which is more preferred owing to higher effectiveness and satisfaction among the patients.
RESUMEN
Short face syndrome (SFS) is a condition with a clinical impression of deficient lower anterior facial height, which is an esthetic disharmony based on vertical facial proportions rather than absolute dimensions. Masseter hypertrophy is one of the etiologic factors in which there is an enlargement of unilateral or bilateral masseter muscles. Clinically, it presents as a quadrangular face characterized by bulging of the mandibular angle giving a muscular appearance. Despite the muscular origin, surgery should be aimed toward bony reduction (osteoplasty) followed by supplemented myotomy. This case report addresses one such case of SFS treated with surgery-first approach and supplemented myotomy with a 1-year follow-up. The esthetic facial profile, pleasant smile and overall good treatment outcome remained stable 1 year after orthognathic surgery and orthodontic treatment.
RESUMEN
OBJECTIVE: To evaluate the nasal patency using acoustic rhinometry (AR) in patients with unilateral cleft lip and palate (UCLP) and to ascertain the rhinological importance of the same. METHODS: Eccovision Acoustic Rhinometer system was used for assessment of nasal cross-sectional area (CSA) and volume in 15 patients with UCLP. The CSA1, CSA2, and CSA3, which represent the CSA at the nasal valve area and anterior end of the inferior turbinate, the anterior half of the inferior turbinate and the anterior end of the middle turbinate, and the region of middle portion of middle turbinate, respectively, were compared on the cleft and non-cleft side. RESULTS: The mean ± SD of CSA1, CSA2, and CSA3 as well as the overall nasal CSA were significantly higher on non-cleft side compared to cleft side (P value < .001). The mean ± SD of nasal volume was also significantly higher in non-cleft side compared to cleft side (P value < .001). CONCLUSIONS: The nasal patency among patients with UCLP demonstrates a range of impairments that can be objectively measured using acoustic rhinometry. The orthodontic, orthopedic, or orthosurgical management of maxillary deficiency in these patients can affect the nasal area and volume and can have an impact on breathing, speech, and sleep. The pretreatment assessment may be useful to identify patients who are at potential risk of deterioration of nasal patency and airway post-intervention. Taking into consideration the multiple diagnostic procedures in the course of long-term multidisciplinary treatment of patients with cleft lip and palate, a noninvasive investigation technique such as AR may be the preferred mode of investigation to ascertain nasal patency.

OBJECTIVES: To compare nasal and upper airway dimensions in patients with cleft lip and palate (CLP) who underwent nasoalveolar molding (NAM) with those without NAM during infancy using acoustic pharyngometry and rhinometry. MATERIALS AND METHODS: Eccovision acoustic pharyngometry and rhinometry (Sleep Group Solutions) was used for assessment of mean area and volume of nasal and upper airway in patients with complete unilateral CLP (age range 16-21 years) treated with NAM (group 1, n = 19) versus without NAM (group 2, n = 22). RESULTS: The mean nasal cross-sectional areas and volume were higher in group 1 compared to group 2 on both cleft (P value <.001) and noncleft side (P value >.05). The mean area and volume of upper airway were also significantly higher in group 1 compared to group 2 (P value <.05). CONCLUSIONS: Nasoalveolar molding being one of the first interventions in chronology of treatment of patients with CLP, its long-term outcome on nasal and upper airway patency needs to be ascertained. The results of the present study show that the patients with CLP who have undergone NAM during infancy have better improvement in nasal and upper airway patency compared with those who had not undergone NAM procedure. The basic advantages of being noninvasive, nonionizing and providing dynamic assessment of nasal and upper airway patency make acoustic pharyngometry and rhinometry a diagnostic tool of choice to be used in patients with CLP.
