بررسی هیستولوژی ساختمان فاسیکلی اعصاب Chorda-Tympani, Lingual در ناحیه دندان مولار سوم تحتانی
Authors
Abstract:
آسیب عصب Lingual یکی از شایعترین عوارض جراحیهای دندانهای مولار سوم تحتانی است و از طرفی، بعد از جراحی میکروسکوپی ترمیم عصب Lingual آسیب دیده، حس چشایی در مقایسه با حس لامسه 3/2 قدامی زبان یا اصلا احیا نمی شود و یا به صورت بسیار جزیی احیا می گردد. در بررسی هیستولوژی اعصاب Chorda-tympani, Lingual ناحیه دندان مولار سوم تحتانی بدست آمده از 200 جسد تازه سازمان پزشکی قانونی کشور، مشخص شد که فاسیکلهای Chorda-tympani بطور گسترده ای در میان فاسیکلهای عصب Lingual پخش می شوند و لذا پس از جراحی میکروسکوپی ترمیم عصب Lingual در این ناحیه، شانس برخورد با فیبرهای چشایی و ترمیم آنها بسیار کم است.

بررسی موقعیت عصب Lingual در ناحیه دندان مولار سوم تحتانی
با توجه به بالا بودن شیوع آسیبهای اعصاب Lingual و Chorda tympani ناشی از جراحی دندان عقل و عوارض عدیده این آسیبها که همگی از عدم اطلاع جراح از موقعیت دقیق آناتومیکی این اعصاب ناشی می شود، به تعیین دقیق این اعصاب از صفحه زبانی زائده آلوئلار فک تحتانی و نیز فاصله آنها از ستیغ زبانی فک تحتانی در ناحیه دندان مولار سوم تصمیم گرفتیم. به همین منظور، تعداد 669 عصب در 430 جسد مورد بررسی قرار گرفت و موقع...

This was a 45-year-old woman that initially consulted for a progressive hearing loss and dizziness of some 6 months of evolution. There were no notable relevant antecedents, while in the physical examination the otoscopy showed a greyish image that protruded in the posterior tympanic areas (Fig. 1a). The preoperative audiometry reflected a nixed right hearing loss with a mean loss in conversati...
full textChorda tympani responses under lingual voltage clamp: implications for NH4 salt taste transduction.
Rat chorda tympani (CT) responses to NH4Cl, ammonium acetate (NH4Ac), and ammonium hippurate (NH4Hp) were obtained during simultaneous current and voltage clamping of the lingual field potential. Although functional and developmental similarities for gustation have been reported for NH4+ and K+ salts, we report here that significant differences are discernible in the CT responses to both salts....
full textNeuropeptides modulate rat chorda tympani responses.
The neuropeptide leptin has been shown to selectively modulate rat chorda tympani (CT) responses to sweet tastants. To explore whether other neuropeptides can modulate such responses, rat whole nerve CT responses to NaCl, HCl, quinine HCl, and sucrose were measured while administering cholecystokinin-8 (CCK-8), substance P(4-11) (SP(4-11)), or calcitonin gene-related peptide (CGRP). To avoid po...
full textChorda tympani neuroma masquerading as cholesteatoma.
Facial nerve neuromas occur throughout the course of the facial nerve and its branches, however lesions occurring on the chorda tympani branch are exceptionally rare. We present a case where the diagnosis was made intra-operatively; the patient was pre-operatively thought to have had a cholesteatoma. Total resection is the treatment of choice for these cases. Early diagnosis, aided by high reso...

This is a cross-sectional study design aimed to determine the prevalence of Chorda Tympani Nerve (CTN) injury and related symptoms following myringoplasty. Thirty patients were included in this study. The methods used were measuring taste thresholds using electrogustometer to map taste threshold on the anterior two-third of the tongue on the operated side with the non operated side as the contr...
