Stepped-tube models with a constriction in the anterior section were used to evaluate the effects that nasal valve passage area and nasal cavity shape have on acoustic rhinometry (AR) measurements. The AR-determined cross-sectional areas beyond a constriction of small passage area were consistently underestimated, and the corresponding area-distance curves showed pronounced oscillations. Also, ...

Branched-tube models can be used for modeling nasal speech such as nasal stops and nasalized vowels. Previously, it has been shown that the use of probabilistic prior information such as smoothness priors can reduce the within-speaker variability of the vocal tract estimates. This model, however, lacked a representation of paranasal cavities and thus a model with a more complex branching struct...

Case description- A two-year-old intact Golden Retriever was affected with the 6-months previous history of blastomycosis and treatment was performed using fluconazole. Clinical findings- Cough, fever, nasal discharge, dry and harsh lung sounds with peripheral lymphadenopathy was observed. Emphysematous change and large pulmonary bulla was reported in computed tomography of the thorax. Treatm...

Sharing the airway is a major concern for both anaesthetist and surgeon because the security of the airway may be jeopardized and the tracheal tube might impede the surgical field. This is seen typically in maxillofacial and ENTsurgeries. Nasal intubation is widely exercised by anaesthetists in maxillofacial surgery but difficulties arise with panfacial fractures when an unobstructed surgical f...

AIMS To prospectively evaluate the reliability and efficacy of a new treatment for the reconstruction of the lacrimal duct using a new histo-engineered material, xenogeneic (bovine) acellular dermal matrix. METHOD Five patients (five eyes) with partial or total absence of the lacrimal duct were included in the study. Four patients (four eyes) suffered from traumatic injuries to the lacrimal d...

PURPOSE To assess the incidence of operative difficulties in endonasal endoscopic dacryocystorhinostomies, as well as to suggest solutions. METHODS This retrospective study searched for reports of complications and intraoperative difficulties in our records of 268 endoscopic endonasal dacryocystorhinostomies, in 241 patients, performed from October 1999 to August 2005. The patients' age range...

At present, exogenous surfactant replacement therapy and mechanical ventilation (MV) remain the ‘Standard of Care’ while treating such infants. However, this requires endotracheal intubation – an invasive procedure associated with complications. Moreover, the skills required to intubate very small babies are not universally available and may vary among the healthcare professionals even in devel...

Eosinophilic otitis media (EOM) shows a very high rate of association with asthma, and intractable otitis media involves marked eosinophil infiltration into the middle ear. The middle ear space is connected to the nasopharynx by the Eustachian tube, and it is considered a part of the upper respiratory tract. Allergic rhinitis and asthma often coexist as chronic inflammatory diseases of the uppe...

BACKGROUND Surgical scarring on the face and disrupted anatomy in the medial canthal area following external dacryocystorhinostomy (DCR) can be avoided by an endonasal approach. This study examined the outcome of direct visualization endonasal DCR, performed by young surgeons and residents. METHODS A retrospective case series of 75 consecutive endonasal DCRs performed under direct visualizati...

A 21-year-old primigravida had a pregnancy complicated by hyperemesis gravidarum (HG) beginning at 7-week gestation. Despite medical therapy, she lost 18% of her prepregnancy weight. Early ultrasound at 14 weeks demonstrated a flattened facial profile with nasal hypoplasia (Binder phenotype) consistent with vitamin K deficiency from HG. She had a percutaneous endoscopic gastrojejunostomy tube p...
