OBJECTIVE: Rarely the tonsillar pillars and the soft palate became adherent to the posterior nasopharyngeal wall by strong fibrous tissue due to excessive dissection and cauterization during surgery leading to nasopharyngeal stenosis. Therefore, many treatment modalities are being tried to cure this problem. The aim of this study is to explore our results of modifying the basic technique to accommodate those patients with combined nasopharyngeal stenosis and tonsillar pillars adhesions in one stage...

INTRODUCTION: Carotid blowout syndrome (CBS) secondary to radiation therapy is life-threatening and requires emergency treatment. More recently, endovascular treatment has provided an effective way to control CBS-related bleeding. CASE DESCRIPTION: We present a case of CBS with a rupture of the internal carotid artery (ICA) pseudo-aneurysm after Gamma Knife radiation therapy for nasopharyngeal carcinoma (NPC). The patient was a 55-year-old man who was transferred to our hospital with severe repetitive epistaxis...

Nasopharyngeal stenosis is a rare sequela of extra-laryngeal tuberculosis that can adversely impact the quality of life of afflicted patients. Relying solely on the oropharyngeal airway, patients often complain of inspiratory dryness and decreased sensation of airflow as the nasal mucosa and turbinate complex is entirely excluded from the breathing mechanism. Often times, the oropharyngeal inlet can be narrowed as well, limiting the air flow through the oropharyngeal airway. In those circumstances, patients often require tracheostomy for establishment of a reliable airway...

REVIEW
Allyson C Berent
Choanal atresia is rare in small animal veterinary medicine, and most cases are misdiagnosed and are actually a nasopharyngeal stenosis (NPS), which is frustrating to treat because of the high recurrence rates encountered after surgical intervention. Minimally invasive treatment options like balloon dilation (BD), metallic stent placement (MS), or covered metallic stent (CMS) placement have been met with success but are associated with various complications that must be considered. The most common complication with BD alone is stenosis recurrence...

Background Holoprosencephaly (HPE) is often accompanied by a deficit in midline facial development; however, congenital oropharyngeal stenosis in neonates with HPE has not been reported before. We describe a case of a neonate with prenatally diagnosed semilobar HPE accompanied by congenital oropharyngeal stenosis. Case Report The patient was born at 39 weeks of gestation and developed dyspnea shortly after. Laryngoscopic test revealed oropharyngeal stenosis. Nasal continuous positive airway pressure, high-flow nasal cannula, and nasopharyngeal airway did not resolve her dyspnea; tracheostomy was required...

REVIEW
D T Ginat, C D Robson
A wide variety of congenital nasal lesions can present to clinical attention due to airway obstruction, the presence of a mass, and/or cosmetic deformity, including pyriform aperture stenosis, choanal atresia, nasopharyngeal atresia, arrhinia, congenital germline fusion cysts, cephaloceles, neuroglial heterotopia, nasolacrimal duct mucoceles, hamartomas, supernumerary nostril, and bifid nose. Computed tomography and magnetic resonance imaging, which are the main imaging modalities used to characterize these lesions, often serve complementary roles...

COMPARATIVE STUDY
Takeshi Kouga, Koji Tanoue, Kiyoshi Matsui
Syndromic craniosynostosis is associated with a high rate of respiratory difficulty, due mainly to midfacial hypoplasia. Nasopharyngeal airway establishment has been reported as the first-line approach to airway obstruction and may obviate the need for a highly invasive tracheotomy. No previous studies have compared airway obstruction status in syndromic craniosynostosis between cases requiring and not requiring airway managements. We focus on nasopharyngeal airway use and airway status outcomes to assess respiratory difficulty in patients with syndromic craniosynostosis...

OBJECTIVE: There are only sporadic reports of delayed sino-nasal complications associated with nasopharyngeal carcinoma (NPC) treated with radiotherapy. These include choanal stenosis, osteoradionecrosis, chronic sinusitis, and intranasal synechiae. Most likely, these complications are underestimated as in many institutions nasal endoscopies in NPC patients are not performed routinely. The aim of this study was to identify the onset and incidence of delayed sino-nasal complications in NPC patients and their effect on quality of life (QOL)...
