[Topical liquid nasal gel, its anatomical distribution and transport]. / Distribución anatómica y transporte de un gel líquido tópico nasal.

The objectives of this study are: 1) to assess the anatomical distribution of a topical liquid nasal gel in patients with and without rhinitis using a metered dose nasal pump, and 2) to determine whether the distribution pattern is influenced by dosage and delivery technique. Thirty-nine volunteers were evaluated, 26 without nasal inflammation and 13 with rhinitis. Patients self-administered the nasal spray according to the specifications in one fossa and incorrectly in the other one (sniffing and double doses). The findings showed that the nasal gel delivered by spray did not penetrate beyond the inferior part of the middle turbinate, regardless of delivery technique (double dose with sniffing or single dose without sniffing) and the presence or absence of inflammation.

[The use of Quality of Life Questionnaire in patients with nasal polyposis]. / Utilidad del cuestionario RSDI para la valoración de la calidad de vida en pacientes con poliposis nasal.

OBJECTIVES: Polyposis handicap evaluation through Spanish validation of the Rhinosinusitis Disability Index. MATERIAL AND METHODS: Spanish validation of the Polyposis Disability Index (PDI). One hundred and fifty one patients referred to our Nose Unit in Fundación Hospital Alcorcón. The Spanish version of the PDI was administered after translation and retrotranslation. Internal consistency and reliability were established. RESULTS: Spanish adaptation of the PDI and ists subscales (functional, emotional and physical) showed a high reliability and internal consistency (Cronbach's alfa: 0,90). CONCLUSIONS: Spanish adaptation of the PDI is valid, reliable and can be used in a clinical setting to quantify the impact of polyposis on patient's quality of life.

[Somnoplasty: treatment of chronic snoring using radiofrequency irradiation of the palate]. / Somnoplastia: tratamiento del ronquido crónico mediante radiofrecuencia sobre el paladar.

The goal of this study is to evaluate the efficacy and the safety of tissue reduction of the palate by means of radiofrequency for the treatment of snoring. Fifty-three patients were evaluated. Eight of them (15%) met criteria for mild OSAS. All of them underwent RF energy treatment with several ablation sites and the mean total energy administered was about 2500 J per treatment session. 40 patients (75%) underwent an additional RF treatment and the energy administered in the second session was the same as in the first one. We evaluated postoperative pain, snoring and the satisfaction of the patient and his enviroment. After a mean follow-up of 20 months no adverse effect was reported. The success diminishes with time as happens other surgical procedures (UPPP or LAUP) but the absence of serious adverse side-effects and the minimal postoperative pain support the use of RF as an effective procedure for reducing snoring.
