Purpose Head rotation is thought to have an effect on obstructive sleep apnea (OSA) severity. However, keeping the head rotated fully during sleep is difficult to maintain, and the effect of head rotation is not the same in all OSA patients. Thus, this study aimed to identify whether less head rotation has an effect on airway patency and determine...

The increasing prevalence of obstructive sleep apnoea (OSA) led to the need to understand upper airway (UA) anatomy and its contribution to the disease process. This review article summarises the current understanding of OSA development in adults. It focuses on UA anatomy and pathophysiology in anatomical subsites including the nasal cavity, soft t...

Introduction: Esophageal tear is a surgical emergency as it is associated with high morbidity and mortality.

Treatment of Submandibular gland enlargement due to either neoplastic or non neoplastic diseases are submandibulectomy. It can be approached via transoral or transcervical. The aim of this case series is to demostrate that transcervical approach is the most preferred way because it allow wider exposure of surgical field and safer. Here, we showed a...

BACKGROUND. Polyps, cysts and mucocele are the commonest sinonasal tumors present unilaterally, as well as invasive tumors, such as inverted papillomas and squamous cell carcinomas. On the contrary, Schwannomas are rare lesions found in this area. MATERIAL AND METHODS. We present a case of a 48-year-old female who presented with a 2-year progressiv...

Peritonsillar abscess (PTA) is one of the deep neck infections. Unilateral PTA is more common than bilateral PTA and is more common in adults than children. Therefore, it is a rare condition with a low rate of incidence. To the best of our knowledge, the literature on this topic (bilateral PTA in children) is limited with this manuscript. In this s...

Olfactory bulb and nasal mucosa are one of the sources for neural stem cell, including the superior and middle turbinates (MT). The middle and inferior turbinates (IT) provides the largest area of nasal mucosa which is technically easier to harvest the stem cell for future transplantation. The ability of nasal respiratory epithelial cells (RECs) an...

Introduction: Congenital tracheal stenosis (CTS) is a serious and rare condition. In most cases, CTS is associated with cardiopulmonary abnormalities; however, isolated CTS is present in 10%-30% of patients. The severity of the disorder is dependent on the symptoms, which correlate with the CTS classification. Case presentation: We discuss our f...

The therapeutic goals of the treatment of allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are symptom relief, avoiding complications, and improving quality of life.
