Results of Endoscopic Transnasal Transsphenoidal Treatment of Prolactin Secreting Pituitary Adenoma / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The endoscopic transnasal transsphenoidal approach is a common approach for pituitary tumor. The objectives of our study is to report indication, efficacy, safety and endocrine result of endoscopic transnasal transsphenoidal surgery in patients with prolactin secreting pituitary adenoma. SUBJECTS AND METHOD: We retrospectively reviewed the medical records of 10 patients who had received endoscopic transnasal transsphenoidal pituitary surgery of prolactin secreting pituitary adenoma. RESULTS: Three patients were resistant and intolerant in medical therapy. Visual symptoms were developed in 8 patients. Postoperatively, 4 patients (40%) achieved normalization of prolactin and relief of symptoms from endoscopic surgery alone. Four of the remaining 6 patients achieved postoperative normalization of prolactin with medication. Visual symptom was improved in all patients. One patient had postoperative diabetes insipidus. CONCLUSION: We believe that the endoscopic method is a safe, hardly invasive and efficient surgical technique in prolactinoma. Medical treatment with dopamine agonist drugs is the mainstay of treatment and endoscopic surgery will be used in cases of drug resistance, intolerance and development of acute visual symptom, we may offer endoscopic surgery as a viable treatment option.

A Case of Postobstructive Pulmonary Edema Following Tracheotomy / 대한이비인후과학회지

Postobstructive pulmonary edema is a recognized complication of acute airway obstruction, especially after endotracheal extubation. It usually follows relief of the obstruction and is likely to be of non- cardiogenic origin. The mechanism by which an upper airway obstruction results in pulmonary edema is likely by the combination of the increased reduction of intrapulmonary pressure, increased capillary permeability and hypoxia. The application of moderate continuous positive airway pressure in conjunction with the administration of diuretics usually clears pulmonary edema in these clinical settings within 24 hours. We encountered a rare case of a 47-years-old female with a postobstructive pulmonary edema that occurred in a patient after relief of upper airway obstruction following intubation of the trachea

A Case of Pneumolabyrinth after Temporal Bone Fracture / 대한이비인후과학회지

Pneumolabyrinth or pneumocochlea is an uncommon condition in which the vestibule or cochlea is filled with air. Although there have been several reports about pneumolabyrinth after stapes surgery, it is rarely found in temporal bone fractures. The presence of air inside the inner ear is a definite proof of a pathological connection between the inner ear and the air-filled mastoid or middle ear cavities. We encountered a rare case of a 45-years-old male with a pneumolabyrinth that resulted from a blunt head trauma. A pneumolabyrinth was resolved spontaneously.
