Spontaneous perforation of the pharynx is an unusual condition. Due to its non-specific presentation and general lack of awareness, diagnosis and intervention may be delayed resulting in potential complications. This case reports a rare spontaneous perforation of the pyriform sinus after a forceful sneeze, leading to cervical subcutaneous emphysema and pneumomediastinum.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare condition related to holoprosencephaly in which bony overgrowth of the medial process maxilla narrows aperture. CNPAS presents neonates with signs upper airway obstruction ranging from mild severe respiratory distress and failure thrive. Surgical intervention indicated after failed conservative measures generally includes temporary s...

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare cause of nasal obstruction. We presented a case of CNPAS with accompanying short lingual frenulum. Surgical dilatation without osteotomy was used, and the infant had normal growth and development. In these cases, the less invasive surgical methods can be effective.

BACKGROUND Optimal aesthetic outcomes from rhinoplasty are heavily influenced by structures adjacent to the nose. Although the importance of the chin has been emphasized since the inception of rhinoplasty, little attention has been given to the forehead. The forehead/glabella/radix complex represents a vital triad in rhinoplasty, from which the nasofrontal angle is derived. In the present study...

Considerable doubt continues to exist about the r6le of finely myelinated and unmyelinatedt visceral afferents in the function of the cerebral cortex. Recent evoked potential studies involving stimulation of the chorda tympani, "" the vagus, 7l and the splanchnic nerves' have failed to establish that impulses transmitted along the slow-conductingt components of these nerves reach the cortex. It...

Our study describes the anatomy of the middle cerebral artery (MCA) in 65 Sprague-Dawley rats and the spatial distribution of ischemic cortical lesions caused by occluding major MCA branches. The rats characteristically had at least two major MCA branches, frontal and parietal. Many rats had additional branches supplying the pyriform and temporal cortexes. Permanent occlusion of the frontal or ...

BACKGROUND Although the lateral pharyngotomy is a well-known surgical procedure, to our knowledge, no published reports have described the results achieved with a lateral pharyngectomy approach in patients with isolated and previously untreated selected invasive squamous cell carcinoma of the lateral wall of the pyriform sinus. METHODS The medical files and operative charts of 30 patients wit...

Introduction: Tuberculosis (TB) is a relatively prevalent infectious disease caused by a bacterium called mycobacterium tuberculosis. It primarily involves the lungs, but it can also affect other organs causing a variety of symptoms.  Case Report: In this report, a rare case with primary involvement of pyriform sinus and vallecula due to tuberculosis in a 74-year-old woman who complained of ody...
