1/12. Alterations in taste sensation: a case presentation of a patient with end-stage pancreatic cancer.Alterations in taste can occur as a result of cancer, cancer treatment, and from a variety of other causes. Cancer patients frequently experience taste alterations, which often go undetected in the clinical setting. This case presentation depicts a 90-year-old client with end-stage pancreatic cancer undergoing chemotherapy treatment with gemcitabine. The symptomatology of taste changes is described. Etiology and rationale for taste changes is presented for the cancer patient population, and for the general population. review of the cancer literature, research instruments, and goals/outcomes are discussed. The author determined that interventional studies are lacking, and research is needed.- - - - - - - - - - ranking = 1keywords = taste (Clic here for more details about this article) |
2/12. dysgeusia due to an orthodontic wire: a case report.A 14-year-old female developed gustatory disorder due to an orthodontic wire having pierced the right trigonal retromolar. The patient's complaints included traction pain on the right lower jaw, numbness on the right front half of the tongue and hypogeusia with the exception of sweet tastes. Possible causes of dysgeusia in this case were: (i) direct mechanical compression of a gustatory nerve by the orthodontic wire; and (ii) disturbance of blood supply to a gustatory nerve by edema that developed in nerve tissues around the wire. The patient's retention of a normal threshold for the recognition of sweet tastes is not fully understood.- - - - - - - - - - ranking = 0.25keywords = taste (Clic here for more details about this article) |
3/12. Unusual complication of tonsillectomy: taste disturbance and the lingual branch of the glossopharyngeal nerve.taste disturbance is an unusual complication of tonsillectomy of which there are very few reports in the literature. The possible causes of this rare complication are: (1) direct or indirect damage to the glossopharyngeal nerve or its lingual branch (LBGN), (2) lack of dietary zinc, and (3) habitual drug intake. We report a 41-year-old man, who complained of taste disturbance following tonsillectomy that was performed for chronic tonsillitis and unilateral (left) tonsillar hypertrophy. During surgery, hypertrophic tonsils were found to be sited deeply into the tonsillar bed, especially at the lower pole of the left tonsil. Pathologic examination following tonsillectomy revealed a keratinous cyst and chronic infection at the left tonsil, and lymphoid hyperplasia and chronic infection at the right tonsil. Although his complaint had been getting better, qualitative examination of his taste function revealed bilateral impairment of the sense of sweet taste on the base of his tongue two months after the surgery, and a taste disturbance of sweet taste on the left side persisted the 10th month after the surgery. His serum zinc value was normal, and he did not take any drug that could affect his sense of taste. Depending on the literature data, possible indirect damage to the LBGN was suspected as the cause of the taste disturbance. This symptom may be reversible within two years after tonsillectomy, but it can also be irreversible. Therefore, tonsillectomy should be performed with minimal trauma to the tonsillar bed, especially when there is an additional pathology extending into the lower pole, and such a patient should be informed of the risk of post-operative taste disturbance after tonsillectomy as being one of the rare complications of this surgery.- - - - - - - - - - ranking = 1.5keywords = taste (Clic here for more details about this article) |
4/12. Posttonsillectomy taste distortion: a significant complication.OBJECTIVE/HYPOTHESIS: tonsillectomy is among the most commonly performed procedures. As with any surgery, head and neck surgeons must be aware of possible complications and their potential affects. At our smell and taste center, we have been referred several patients in a 6-month period with the complaint of taste distortion after tonsillectomy. We report in this article a patient that complains of taste distortion after a right tonsillectomy for unilateral tonsillar hypertrophy. STUDY DESIGN: A prospective study documenting taste distortion after tonsillectomy using clinical, subjective, and objective evaluation. methods: The clinical course of a patient with taste distortion after a tonsillectomy is described. The gustatory function was investigated by conducting electrogustometry and spatial taste testing. Threshold measurements were determined at three left- and three right-side tongue regions: 1) the tongue tip region (innervated by the chorda tympani branch of the facial nerve), 2) the lateral margin of the tongue (anterior to the foliate papillae), and 3) the posterior tongue region (innervated by the lingual branch of the glossopharyngeal nerve). RESULTS: After a complete clinical evaluation and taste testing, it was found that the patient suffered an injury to the right lingual branch of the glossopharyngeal nerve. The close anatomic relationship between the palatine tonsil and lingual branch of the glossopharyngeal nerve makes the nerve vulnerable during tonsillectomy. This injury has caused the patient to suffer ageusia to the right posterior one third of the tongue, compensated by a contralateral phantogeusia (phantom taste) with clinical dysgeusia. The phantogeusia was abolished by application of anesthetic to the area where the phantom was perceived. We propose that the phantogeusia is the result of release-of-inhibition in the contralateral glossopharyngeal nerve. CONCLUSION: taste distortion (including, phantogeusia and dysgeusia) after tonsillectomy is rarely reported as a complication but has a significant impact on quality of life. This article examines the taste distortion presence as a complication after tonsillectomy to make head and neck surgeons aware of this serious complication and the pathophysiology of taste distortion.- - - - - - - - - - ranking = 1.75keywords = taste (Clic here for more details about this article) |
5/12. "I can't taste ice cream": an unusual case of tinnitus and dysgeusia.Auricular foreign bodies are usually presented to the emergency department in an easily recognizable fashion. We report the case of a 16-year-old male who presented to the emergency department with complaints of unilateral tinnitus and dysgeusia. He denied any history of injury except for falling from his bike in the woods earlier that day. On examination, a wooden foreign body was found in the external auditory canal. A computed tomography scan revealed a 3-cm-long twig that pierced the middle ear disrupting the ossicles. He was taken to the operating room for removal and microscopic evaluation. On evaluation, the chorda tympani nerve was found to be severed along with disruption of the ossicles. This is an unusual presentation for an aural foreign body, and the resulting injury of the chorda tympani is not well published. One should consider the possibility of injury to the middle and inner ear and perform the necessary clinical evaluation before and after removal of aural foreign bodies.- - - - - - - - - - ranking = 0.5keywords = taste (Clic here for more details about this article) |
6/12. A case of Cronkhite-canada syndrome with taste disturbance as a leading complaint.Cronkhite-canada syndrome was first described in 1955. The clinical features of this rare syndrome of unknown etiology include nonhereditary gastrointestinal polyposis together with diarrhea, nail dystrophy, alopecia, and hyperpigmentation of the skin. This syndrome has been divided into five clinical types based on initial symptoms. We describe a case of Cronkhite-canada syndrome presenting with taste disturbance as the major symptom, present a comprehensive review of the literature concerning this rare syndrome, and suggest therapeutic treatment options.- - - - - - - - - - ranking = 0.625keywords = taste (Clic here for more details about this article) |
7/12. Unpleasant sweet taste: a symptom of SIADH caused by lung cancer.A 56 year old woman with large cell lung carcinoma complained of an unpleasant sweet taste (dysgeusia). She developed hyponatraemia caused by the syndrome of inappropriate antidiuretic hormone secretion (SIADH). dysgeusia disappeared when serum sodium normalised and recurred when hyponatraemia relapsed. dysgeusia was the initial and only symptom of SIADH in this case.- - - - - - - - - - ranking = 0.625keywords = taste (Clic here for more details about this article) |
8/12. Dysosmia and dysgeusia presenting as depression.Disorders of taste and smell are underrecognized and often misdiagnosed. Two cases are described in which patients mistakenly thought to suffer from depression actually had unnoticed drug-induced dysosmia and dysgeusia. Also reviewed are psychiatric, neurologic, and medical disorders and drugs that cause abnormalities of taste and smell, and some behavioral aspects of food aversions. Three groups, all of whom may superficially appear depressed, must be distinguished from each other: 1) patients with dysosmia or dysgeusia, 2) patients with primary neuropsychiatric illness with olfactory or gustatory hallucinations, and 3) patients with conditioned taste aversions.- - - - - - - - - - ranking = 0.375keywords = taste (Clic here for more details about this article) |
9/12. Sweet taste (dysgeusia). The first symptom of hyponatremia in small cell carcinoma of the lung.Three patients with small cell carcinoma of the lung presented with a persistent unpleasant sweet taste as their initial and only symptom. On further evaluation, they were found to have hyponatremia secondary to the syndrome of inappropriate secretion of antidiuretic hormone. In each case, resolution of the sweet taste paralleled an increase in serum sodium concentration after water restriction alone. Linkage of the sweet taste with a low serum sodium concentration strongly implicates hyponatremia--rather than tumor, antidiuretic factor, medications, or chemotherapy--as the central mechanism responsible for this previously unreported (to our knowledge) sentinel symptom of small cell carcinoma of the lung.- - - - - - - - - - ranking = 0.875keywords = taste (Clic here for more details about this article) |
10/12. Trigeminal sensory neuropathy with abnormal taste following acute sinusitis.We report a case of isolated trigeminal sensory neuropathy associated with impairment of taste sensation following acute sinusitis. Sensory disturbance was distributed mainly in the ophthalmic division, and partly in the maxillary and mandibular divisions. No other cranial nerves were involved. An otological procedure resulted in complete recovery. The unique combination of trigeminal neuropathy and abnormal taste seemed to be caused by the infectious process involving the gasserian ganglion of the trigeminal nerve.- - - - - - - - - - ranking = 0.75keywords = taste (Clic here for more details about this article) |
