This case report presents two very unusual cases of melanomas arising within the masseter muscle. Both were metastases of unknown origin arising in young, healthy patients and presenting as asymptomatic lesions. No primary lesions were found in either case. A comprehensive search of the world literature revealed no previous similar cases.
A 72-year-old patient with a Warthin's tumor of the right parotid gland developed massive necrosis of the tumour associated with temporary facial palsy with subsequent macroscopic tumour disappearance.
We report a prospective, controlled trial to assess temporomandibular joint (TMJ) dysfunction following the use of a Boyle-Davis mouth gag during tonsillectomy. TMJ function was evaluated in patients undergoing tonsillectomy and a control group undergoing nasal surgery preoperatively and 6 weeks postoperatively. The main outcome measures were symptoms and signs of TMJ dysfunction and interincisal distance. A mean reduction of 0.89 mm in interincisal distance (P < 0.01) was noted postoperatively in the tonsillectomy patients. There was no statistically significant reduction of interincisal distance in patients undergoing nasal surgery. There was a statistically significant reduction in interincisal distance in the post-tonsillectomy patients, caused by fibrous healing of the tonsillar bed or fibrous ankylosis of the TMJ.
A study undertaken to assess the olfactory acuity in allergic (group I) and non-allergic rhinitis (group II) patients in comparison with age and sex matched controls (group III). Patients presenting with atleast three of the five cardinal symptoms of rhinitis i.e. rhinorrhoea, sneezing, itching, headache and nasal obstruction were grouped as non-infective rhinitis and further divided into allergic rhinitis (group I, n = 20) and non-allergic rhinitis (group II, n = 20) based on nasal smear cytology positivity or negativity for eosinophils respectively. Detailed Ear, Nose and Throat examination was carried out in both the groups and peripheral blood samples were analysed for total, differential leukocyte and absolute eosinophil counts using standard techniques. In all the three groups the olfactory thresholds for 5 odorants i.e. musk (M), formalin (F), camphor (C), asafoetida (A, 10% aqueous solution) and oil of peppermint (P, 20%) were evaluated for testing musky, pungent, camphorous, putrid and minty odours respectively by the method described by Elsberg and Levy for quantitative olfactometry. The results indicated elevation of olfactory thresholds (delta %, calculated taking control values as 100%) for 4 or 5 odorants in group I and group II patients respectively as compared with controls (group I: delta % for P--89.6%; M--116.4%; A--55.8%; P < 0.001; C--73.1%; P < 0.02; F--26.6% N.S.; group II: P--96.9%; M--99.3%, P < 0.01 for both; A--66.8%; C--102.7%, P < 0.001; F--42%, P < 0.05). In the non allergic rhinitis group the magnitude of the olfactory loss was more severe except for the odorant musk. Further interpretations as per gender based specificities revealed more severe olfactory loss in males of both the groups for the odorants peppermint and musk and moderately severe olfactory loss for formalin and camphor as compared to females. However, for the odorant asafoetida females showed greater olfactory loss than males in both the groups (delta % 73.38% versus 52% in group I and 81.29% versus 69.7% in group II).
