BACKGROUND Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. METHODS Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objectiv...

OBJECTIVE To determine functional results after lateral semicircular canal fenestration on congenital conductive hearing loss. STUDY DESIGN Case series with chart review. SETTING Amir-Alam otolaryngology tertiary referral center. SUBJECTS AND METHODS Twenty patients with congenital oval window malformations who were not candidates for ossicular reconstruction underwent lateral semicircula...

aim and background:   safe airway maintenance in patients under general anesthesia is the most important duty of anaesthesiologists. classic laryngeal mask airway (clma) is a supra-glottic device to achieve this aim. there are different insertion techniques for this device, but the best of them is unknown. methods and materials:   two hundred patients were included in this mono-blinded clinical...

In this paper, we investigate the universal filtered multi-carrier system (UFMC) for 5G and subsequent connections with aid of MATLAB package. It can be considered that UFMC technology provides an advantage against inter-symbol interference (ISI) as well inter-carrier (ICI) low latency. The proposed is simulated analyzed in terms error rates, complementary cumulative distribution function (CCDF...

Maxillary sinus floor elevation via a lateral approach is a predictable technique to increase bone volume of the edentulous posterior maxilla and consequently for dental implants placement. The sinus floor is elevated and it can be augmented with either autologous or xenogeneic bone grafts following an opening bone window created on the facial buccal wall. Maxillary septa are walls of cortical ...
