Empty sella syndrome, diagnosed as allergic rhinitis.

Unilateral cerebrospinal fluid (CSF) rhinorrhea as the only manifestation of the primary empty sella syndrome is a rare event. A case of a middle-aged male patient complaining for intermittent unilateral rhinorrhea, which started 5 months earlier, is reported. The persistence of this state was attributed to an allergic rhinitis. The initial work-up excluded the above diagnosis and an erroneous radiological diagnosis led to a puncture of the left maxillary sinus. A lateral X-ray of the skull and CT scan led to the diagnosis of empty sella syndrome, possibly due to an adenoma or a meningocele.

Use of the excimer laser in stapes surgery and ossiculoplasty of middle ear ossicles: preliminary report of an experimental approach.

Surgery of the stapes may cause a number of complications, including hearing deficits and balance disorders. This has made it necessary to look for improved techniques. Small-fenestra stapedotomy has recently been popularized. Lasers have been advocated for use in fenestrating the stapes footplate. On the other hand, sculpting the middle ear ossicles during tympanoplasty is often necessary for the reconstruction of the ossicular chain and the improvement of sound conduction. Using an excimer laser with a wavelength of 193 nm, fenestrations of the footplate and ossicular sculpting were performed on ossicles obtained during ear surgery and from human cadaver temporal bones. The results indicate that the excimer laser can be used effectively and accurately on an experimental basis and that further research is needed before this method can be used for clinical purposes.

[Paraganglioma of the nodose ganglion of the n. vagus].

A case of a 47-years-old female patient treated for a vagal body tumor is presented. The origin, clinical appearance and special diagnostic and therapeutic problems created by this rare tumor are discussed.

Granular cell myoblastoma of the larynx.

Two cases of granular cell myoblastoma of the larynx are presented. In the first case the tumour was excised by laryngofissure, and in the second case by microlaryngoscopy. Based on this experience a review of this interesting tumour is made, and emphasis is given to the fact that this neoplasm may be mistaken for squamous cell carcinoma.

A schwannoma of the parotid gland. Report of a case.

An unusual case of multiple schwannomas of the parotid gland in a 44-year-old male is presented, and the natural history of the disease is discussed. Neural tumours of the salivary glands are rare, and the treatment of choice is surgery. Recurrence seems to be unusual unless the excision is incomplete.
