INTRODUCTION Nasal obstruction is a common symptom in childhood, related to rhinitis and pharyngeal tonsil hypertrophy. In the presence of nasal obstruction, nasal patency may be reduced, and nasal breathing is replaced by mouth breathing. Orofacial and otorhinolaryngologic changes are related to this breathing mode. Objective evaluation of upper airways may be obtained through nasal patency me...

OBJECTIVES/HYPOTHESIS For a wide exposure of skull base and preservation of septal mucosa, we have raised bilateral modified nasoseptal rescue flaps in the endoscopic endonasal transsphenoidal approach (EETSA) and evaluated the usefulness of these flaps elevation. STUDY DESIGN Case series. METHODS The study population comprised the patients who underwent EETSA with bilateral modified nasose...

Introduction Nasal septal perforation is the loss of composite tissue comprising mucosa, bone or cartilage structures that form nasal septum. septum has many causes. Though it may be idiopathic, most common causes are iatrogenic like surgeries. Among other reasons hematoma, picking habit, cauterization due to nosebleeds, nasotracheal intubation, cocaine use, vasculitis, inflammatory diseases su...

A one-step surgical procedure is presented, including maxillary sinus floor elevation in association with functional endoscopic sinus surgery to remove rhino-sinusal malformations or pathoses that might contraindicate sinus floor elevation. Over a 2-year period, 10 patients requiring a sinus floor augmentation procedure to restore the missing dentition with endosseous implants, but presenting w...

choanal polyps are a form of nasal polyps that grow toward the choana with a single stalk. septochoanal polyp is a rare entity that originates from the mucosa of the nasal septum with choanal extension. the most common site of its origin is mainly the superior aspect of the posterior portion of the nasal septum. however, metaplastic ossification is a rare event in nasal polyp and to the best of...

Trapezoidal roadways in large inclination coal seams show asymmetrical tectonic characteristics, while there is still a lack of theoretical results on stress, deformation, and efficient effective supporting methods high walls. In this paper, based the geological characteristics large, inclined seam roadway, mechanical model for stress–deformation analysis trapezoidal section roadway was establi...

Previous work confirmed the abnormal potential difference between the undersurface of the inferior nasal turbinate and a reference electrode in cystic fibrosis, but the technique is difficult and the results show overlap between the cystic fibrosis and the control populations. In the present study the potential difference from the floor of the nose has therefore been assessed in normal subjects...
