El paciente roncador: evaluación y alternativas terapéuticas / The snoring patient: evaluation and therapeutic alternatives

El ronquido es un problema altamente prevalente, que afecta a millones de personas a nivel mundial. Impacta negativamente en la calidad de vida al afectar la relación de pareja y la calidad de sueño, además de constituir un factor de riesgo cardiovascular. El objetivo de esta revisión es analizar y discutir los aspectos más relevantes de esta condición, desde su etiopatogenia hasta las diferentes alternativas terapéuticas disponibles. En la evaluación del paciente roncador se debe realizar un minucioso examen de nariz, boca, faringe, cuello y esqueleto facial, además de estimar el riesgo de que exista una apnea obstructiva del sueño asociada. Son de utilidad una serie de cuestionarios que permiten asignar puntaje a la sintomatología del paciente y evaluar su impacto en la vida diaria. En general, el estudio deberá incluir exámenes radiológicos, endoscopías de la vía aérea superior (con el paciente despierto y bajo sueño inducido por medicamentos) y estudios del sueño, que se pueden realizar tanto en forma ambulatoria como hospitalizado. Existe una amplia gama de tratamientos disponibles para el ronquido, los que han demostrado una alta efectividad en diferentes subgrupos de pacientes: bajar de peso, dejar de fumar, medicamentos antialérgicos, terapia postural, ejercicios faríngeos, dispositivos de avance mandibular y procedimientos quirúrgicos que van desde intervenciones mínimamente invasivas hasta procedimientos avanzados como cirugía robótica, avances máxilo-mandibulares y la estimulación del nervio hipogloso. Es clave para manejar exitosamente el ronquido el realizar una evaluación detallada del paciente y establecer un plan terapéutico personalizado.

Snoring is a highly prevalent problem, affecting millions of people worldwide. It negatively impacts quality of life by affecting couple relationships and sleep quality, as well as being a cardiovascular risk factor. The aim of this review article is to analyze and discuss the most relevant aspects of this condition, ranging from its etiology and pathogenesis to the different available therapeutic options. When evaluating a snoring patient, a thorough examination of the nose, mouth, pharynx, neck and facial skeleton should be performed, and the risk of having an associated obstructive sleep apnea must be estimated. A series of questionnaires are useful to assign scores to the patient's symptoms and assess their impact on daily life. In general terms, patient evaluation should include radiological examinations, upper airway endoscopies (awake and under drug-induced sleep) and sleep studies, which can be performed both on an outpatient or inpatient basis. There is a wide range of treatments available for snoring, which have shown high effectiveness in different patient subgroups: weight loss, quitting smoking, anti-allergic medications, postural therapy, pharyngeal exercises, mandibular-advancement devices and surgical procedures ranging from minimally invasive interventions to advanced procedures such as robotic surgery, maxillomandibular advancement and hypoglossal nerve stimulation. The cornerstone for a successful snoring management is to perform a detailed patient evaluation and to establish a personalized therapeutic plan.

Differences in patients derived from otolaryngology and other specialties with sleep apnea.

BACKGROUND: Snoring is a main concern in patients who consult an otolaryngologist (ENT physicians) and patients who have cardiovascular comorbidities or excessive daytime sleepiness who usually consult with other specialists. The aim of this study was to describe the clinical differences in patients with obstructive sleep apnea (OSA) referred from ENT or other specialists. METHODS: A prospective study was carried out between June 2015 and July 2018 in a tertiary center. We included patients with suspected OSA referred by the Home Sleep Apnea Test (HSAT) from different specialties such as ENT or other specialties. The main outcome measures of our study were demographic characteristics, clinical characteristics, sleep questionnaire results and HSAT results between OSA patients referred from ENT or other specialists. We used a t-test and chi-squared test for analysis. The diagnostic accuracy of the sleep questionnaires was achieved using receiver operating characteristic (ROC) curve and the area under the curve (AUC). RESULTS: A total of 481 patients were included. OSA was occurred in 82.4% of the subjects (90 in ENT and 306 in other specialties). Patients with OSA referred from other specialists were older than ENT patients (55 ± 13 vs 44 ± 12; p < 0.001), there was more obesity (IMC 31 ± 5.0 vs 28.7 ± 3.8; p < 0,001), a larger neck circumference (42.2 cm ± 3.7 vs 40.6 cm ± 3.0; p < 0.001) and more reported comorbidities (p < 0.001). ENT patients reported mild OSA (46% vs 31%, p = 0.015) and more positional apnea (62% vs 39%, p = 0.002). In this group, the STOP-BANG questionnaire showed an AUC 0.695 vs AUC 0.804, and for sensitivity, the best cutoff was 4 points. Patients referred from otorhinolaryngology are different from those referred from other specialties. Clinical evaluation and screening of OSA should be patient-centered according to these clinical findings.
