Review Case ReportsAtypical eosinophilic angiocentric fibrosis on nasal septum.
Eosinophilic angiocentric fibrosis (EAF) is a rare benign condition of unknown aetiology and is most commonly found in the nasal septum and sinus mucosa. We report a case of EAF and present a review of the available literature. A 51-year-old man with progressive nasal obstruction was referred to our hospital. ⋯ Histologically, it resembled granuloma faciale. However, our case was considered to be an EAF although eosinophilic vasculitis and onion skinning were not observed. This was because a cutaneous lesion was absent and the lesion was limited to the nasal septal mucosa.

The aim of this prospective, single-blind study was to assess the variations in the blood levels of PaO(2), PaO(2)/FiO(2), PaCO(2), and acid-base balance of patients undergoing laryngeal microsurgery under general anesthesia using small-bore endotracheal tubes. ⋯ Laryngeal microsurgery under general anesthesia can be performed using small-bore endotracheal tubes. This is not likely to have any adverse effects on a patient's blood gases and acid-base balance unless the operation lasts longer than 105 min.

Case ReportsPost-traumatic pseudomeningocele presenting as a cyst of external auditory canal: report of a case.
Pseudomeningoceles are formed by extravasation of cerebrospinal fluid through a dural defect into soft tissue. They mostly form as a result of surgical trauma to the dural covering of the lumbar or cervical spine surgery, especially during laminectomy. Howerver, post-traumatic pseudomeningocele rarely occurs in the head and neck. ⋯ The right ear was explored and mastoid antrum was partially filled with a cyst connected to the dural defect. The extradural portion of the mass was removed, the dural defect was repaired with a temporalis fascia-cartilage graft. Clinical manifestations, diagnosis and surgical approaches for post-traumatic pseudomeningocele arising in the head and neck region are briefly discussed.
