Cystic fibrosis (CF) is an inherited disease that primarily affects the lungs and the digestive system, however, it also affects a number of other organs and systems. More than 90% of mortality of  CF patients is due to lung complications.  Healthy lungs are important for a long life for people with CF, We will discuss two important topics for maintaining respiratory health. Chronic use of drug...

In this clinical trial 100 children less than 4 years old,who had  underwent non-pharyngeal surgeries in Kerman university hospitals were selected randomly and investigated for early airway complications after tracheal extubation.patients were divided into two groups:the first group(n=50) were extubated while they were still anesthetised and the second group(n=50) were extubated after regaining...

Ensuring control and protection of the airway for surgical procedures requiring general anesthesia is the cornerstone of clinical anesthesia practice. Successful tracheal intubation is absolutely needed for head and neck cancer surgery because access to the airway is shared by surgeons and anesthesiologists. The approach, oral or nasal, depends on surgical requirements and the patient’s ability...

BACKGROUND The purpose of the study is to compare the effects on the pharyngeal airway space of skeletal anchored face mask with those of tooth-borne facemask. METHODS We used two types of facemask for maxillary protraction, the tooth-borne facemask (TBFM) and the skeletal anchored facemask (SAFM), and evaluated the effects of each facemask on the pharyngeal airway. Twenty-eight patients (mea...

BACKGROUND Recent studies suggest advantages of muscle relaxants for facemask ventilation. However, direct effects of muscle relaxants on mask ventilation remain unclear because these studies did not control mechanical factors influencing ventilation. We tested a hypothesis that muscle relaxants, either rocuronium or succinylcholine, improve mask ventilation. METHODS In anesthetized adult per...

OBJECTIVE The purpose of this study was to compare the morphologic changes of the upper airway space in Class III patients who underwent mandibular setback or bimaxillary surgery (maxillary advancement and mandibular setback) by computed tomography at 2 levels: soft palate and base of tongue. METHODS The sample consisted of 47 subjects in 2 groups who had been diagnosed as having Class III sk...

Orthognathic surgery has been used regularly to treat dentofacial deformities. The surgical procedures affect both the facial appearance as well as the posterior airway space (PAS). Our current literature indicates that setback procedures produce an inferior repositioning of the hyoid bone and posterior displacement of the tongue and the soft palate. These movements cause anteroposterior and la...

Purpose. The upper airway space is significant in orthodontic diagnosis and treatment planning. The objectives of this study are to assess the dimensions of soft tissue elements of the upper pharyngeal space and evaluate potential correlations with modifying variables such as gender, skeletal class, and anthropometric parameters. Materials and Methods. Lateral cephalograms were obtained from 11...

There are numerous medical and surgical treatment modalities for the management of the sleep apnea patient. Among the medical treatments, weight loss and positive pressure therapy are considered to be the most important. Surgical treatment is directed at increasing the posterior airway space. Among the surgical procedures, tracheostomy, uvulopalatopharyngoplasty (UPPP), and maxillofacial skelet...

the laryngeal mask airway (lma) is an important addition to the anesthetist's equipments. however, its usage may involve some complications. we have encountered an unusual and potentially serious complication using this equipment. a 45-year old man underwent cataract surgery under general anesthesia. after the induction of anesthesia, a size 4 of the reusable classic lma was inserted without an...
