Pneumatized superior turbinate as a cause of headache.

BACKGROUND: A pneumatized superior turbinate is a rare cause of headache. Nasal endoscopy alone, does not provide us with adequate information for this inaccessible area of the superior nasal cavity. A coronal computed tomography (CT) must be obtained to confirm the diagnosis. CASE PRESENTATION: We present a 40-year-old female with migraine-type headache and nasal obstruction. Nasal endoscopy revealed a mild septal deviation, a right middle concha bullosa and a paradoxically curved middle turbinate on the left side. Coronal CT-scan showed also the presence of a superior concha bullosa on the left, which was in close contact with the nasal septum. The patient underwent septoplasty and bilateral endoscopic sinus surgery, including partial removal of both the pneumatized middle turbinates in conjunction with gentle lateralization and resection of the lower half of the left superior turbinate. Prompt relief from headache and nasal symptoms was obtained. CONCLUSION: Pneumatized superior concha causing migrainous headache is a rare finding. Endoscopic surgery may provide permanent relief of symptoms.

Normative values of olfactory function testing using the 'sniffin' sticks'.

OBJECTIVES: Quantitative olfactory assessment is often neglected in clinical practice, although olfactory loss can assist to diagnosis and may lead to significant morbidity. "Sniffin' Sticks" is a modern test of nasal chemosensory performance that is based on penlike odor-dispensing devices. It consists of three tests of olfactory function: odor threshold, odor discrimination, and odor identification. The results of this test may be presented as a composite threshold-discrimination-identification (TDI) score. The aim of this study was first to develop normative data of olfactory function for the Greek population using this test and second to relate olfactory performance to age, sex, and side examined. STUDY DESIGN: The authors conducted a prospective clinical trial. METHODS: A total of 93 healthy subjects were included in the study, 48 males and 45 females, mean age of 44.5 years (range, 6-84 years). RESULTS: A database of normal values for olfactory testing was established for the Greek population. Females performed better than males and older subjects performed less efficiently in all tests. We also found a right nostril advantage compared with the left. Additionally, scores obtained from bilateral presentation were similar with scores obtained from the nostril with the better performance. CONCLUSIONS: The "Sniffin' Sticks" can be used effectively in the Greek population to evaluate olfactory performance. Mean values of olfactory tests obtained were better in comparison with data from settings located in central and northern Europe.

Ethmoidal osteoma with intraorbital extension: excision through a transcutaneous paranasal incision.

PURPOSE: To describe a case of conjunctival hyperaemia and proptosis of the right eye. METHODS: Three-dimensional computed tomography (CT) was performed to reveal the size and position of a lesion of osseous density extending into the right orbit. The lesion was then excised using a right paranasal transcutaneous approach. RESULTS: The pathology report suggested ethmoidal osteoma. The postoperative course was uncomplicated and the lesion did not recur during a 5-year follow-up period. Repeated postoperative ophthalmic examinations revealed preservation of visual acuity and visual fields postoperatively. DISCUSSION: Diagnosis is based on imaging studies, especially CT and three-dimensional CT scans. A three-dimensional CT scan is critical in understanding the actual dimensions of the tumour and its relations with other structures. Surgical removal is indicated in cases with orbital matrix compression and displacement. A transcutaneous paranasal approach allows for increased exposure of affected structures.

Unusual retrograde movement of a safety-pin ingested by an infant.

UNLABELLED: Here we present the first reported case of an ingested open safety-pin in a 7-mo-old boy that migrated from the stomach to the oesophagus. CONCLUSION: This rare complication is probably due to a gastro-oesophageal reflux effect, and for this reason we propose that all infants with safety-pins and other sharp objects in the stomach should be positioned in a semi-upright position.
