Quadrupedal head position enhances recovery from chronic maxillary sinusitis - Corrected Proof

June 3, 2013, 12:00 pm by American Journal of Otolaryngology - Head and Neck Medicine and Surgery - Articles in Press

Abstract: Objectives: The position of human maxillary ostia is high on their superomedial walls, which may be suboptimal for natural drainage. Human maxillary sinuses exhibit better passive drainage through their ostia when tilted anteriorly to mimic a quadrupedal head position. We all know that sufficient drainage is very important for the treatment of chronic rhinosinusitis (CRS). Chronic maxillary sinusitis (CMS) is the high incidence of CRS. The aim of this study was to investigate the efficacy of quadrupedal head position in patients with CMS.Methods: One hundred six patients diagnosed with CMS were enrolled. Patients were randomized to quadrupedal head position group and non-quadrupedal head position group for 6weeks of treatment. Treatment outcomes were measured using 1) Lund-Mackay scoring system of pre-and post-treatment computer tomography (CT); and 2) Sinonasal Quality-of-Life (QoL) Survey completed at baseline and 6weeks of therapy.Results: There were statistically significant differences in QoL scores and CT scores between quadrupedal head position group and non-quadrupedal head position group. The quadrupedal head position group had much more improvements in QoL scores and CT scores than that of non-quadrupedal head position group. One patient in the quadrupedal head position group required functional endoscopic sinus surgery (ESS) due to persistent symptoms, and nine patients in non-quadrupedal head position group needed ESS. There were less patients that required ESS in the quadrupedal head position group than in the non-quadrupedal head position group.Conclusions: The improvements of QoL scores and CT scores were significantly better in the quadrupedal head position group than that in the non-quadrupedal head position group. Quadrupedal head position can be valuable adjuvant therapy for patients with CMS.
