Mental Nerve (mental + nerve)
Selected AbstractsInfluence of topical capsaicin on facial sensitivity in response to experimental painJOURNAL OF ORAL REHABILITATION, Issue 1 2007Y.-S. LEE summary, Capsaicin, the pungent component of the red pepper, has been used as an analgesic in a variety of pain conditions, but sensory impairment after long-term treatment has been concerned. This study investigated the influence of topical capsaicin on various types of sensations including pain in the facial areas innervated by the mental nerve, and also evaluated whether the measurement of cutaneous current perception threshold (CPT) is reliable for the quantification of sensory change following capsaicin application. Twenty healthy subjects were given topical capsaicin cream (0·075%), which was applied to the mental area unilaterally, four times daily for 2 weeks. Burning sensation after capsaicin application gradually decreased with repeated applications. Repeated topical capsaicin resulted in reduced sensation to mechanical, heat and cold pain without changing non-painful tactile sensation. It also resulted in increased CPTs at 5 Hz and 250 Hz stimuli but no change in the CPTs at 2000 Hz from the first evaluation after capsaicin treatment and throughout the treatment period. This study demonstrated that topical capsaicin treatment for the management of chronic localized pain can be safely applied to the face without affecting non-painful normal sensations, and that CPT testing is a clinically useful tool for the quantification of sensory changes following capsaicin application. [source] Donor-site morbidity in buccal mucosa urethroplasty: lower lip or inner cheek?BJU INTERNATIONAL, Issue 4 2005Stefan Kamp Authors from Germany debate the issue as to whether the donor site for oral mucosa used in urethroplasty should be taken from the inner cheek or the lower lip, using morbidity as a deciding factor. As a result of their study they have changed their technique, now using the inner cheek as the donor site whenever possible. OBJECTIVE To evaluate donor-site complications of buccal mucosa urethroplasty and whether there is a difference in morbidity between harvesting the mucosa graft from the inner cheek or the lower lip. PATIENTS AND METHODS Twenty-four consecutive patients with recurrent urethral strictures were treated with buccal mucosa urethroplasty in our department between September 2002 and April 2004. In 12 patients the graft was harvested from the lower lip or cheek and lower lip (group 1), and in 12 patients from the cheek (group 2). The mean (range) age of patients was 51 (26,66) years in group 1 and 53 (32,75) years in group 2. The mean (range) graft length was 6.2 (2,16) cm in group 1 and 5.7 (2,13) cm in group 2. All patients were followed up using a mailed questionnaire that asked about pain, numbness, difficulties in mouth opening or ingestion, and satisfaction, monthly for the first 3 months and then every 6 months. The mean (range) follow-up was 12.5 (6,23) months. RESULTS There were no bleeding complications or disturbances in wound healing. All of the patients reported numbness in the area of the mental and buccal nerves, and graft-site tenderness after surgery. In group 1, the pain lasted for a mean (range) of 5.9 (0.5,22) months, compared to 1 (0.1,7) months in group 2 (P = 0.022). Perioral numbness lasted for a mean (range) of 10.3 (0.5,23) months in group 1 and 0.85 (0.1,3) months (P = 0.0027) in group 2. There were no statistically significant differences in problems with mouth opening or food intake between the two groups, but the patients in group 1 seemed to be less satisfied (6/12 patients satisfied) than those in group 2 (11/12 patients satisfied). CONCLUSIONS Buccal mucosa graft harvesting from the lower lip and the inner cheek are both feasible, but harvesting from the lower lip resulted in a significantly greater long-term morbidity, which resulted in a lower proportion of satisfied patients. This seems to be due to a long-lasting neuropathy of the mental nerve. We therefore have changed our technique entirely from lower lip to inner cheek graft harvesting, whenever possible. [source] Clinical Assessment and Surgical Implications of Anatomic Challenges in the Anterior MandibleCLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 4 2003Nuri Mraiwa BDS ABSTRACT Background: The anterior mandible is generally considered a rather safe surgical area, involving few risks of damage to vital anatomic structures. Nevertheless, both neurosensory disturbances and hemorrhages have been reported after implant surgery in that particular area. Purpose: With the increasing demand for oral implant placement, the anatomy of the anterior mandible should receive more attention. This review will focus on the anatomic peculiarities of the anterior mandible and the related clinical implications. Methods: The scientific evidence on the anatomic, histologic, physiologic, and clinical aspects of the neurovascularization of the anterior mandible will be reviewed. Results: Surgical complications may be attributed to the existence of a mandibular incisive canal with a true neurovascular supply. Potential risks may also be related to the presence of the lingual foramen and anatomic variations, such as an anterior looping of the mental nerve. Conclusions: Preoperative radiographic planning for oral implant placement in the anterior mandible should therefore not only consider all esthetic and functional demands but should also pay particular attention to the anatomic peculiarities of this region to avoid any neurovascular complications. [source] Ramus or Chin Grafts for Maxillary Sinus Inlay and Local Onlay Augmentation: Comparison of Donor Site Morbidity and ComplicationsCLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 3 2003Jaime Clavero DDS ABSTRACT Background: The placement of endosseous implants in edentulous areas is frequently limited by inadequate bone volume of the residual ridge. Local bone grafts from the mandible are a convenient source of autogenous bone for alveolar reconstruction prior to implant placement. Purpose: The aim of the present study was to document and compare the morbidity and the frequency of complications occurring at two intraoral donor sites: the mandibular symphysis and the mandibular ramus. Material and Methods: This study reviewed 53 consecutively treated patients:29 with autogenous bone grafts from the mandibular symphysis and 24 with mandibular ramus bone grafts. Each patient received a questionnaire 18 months after surgery regarding problems that may have occurred during the postoperative period. Results: In the patients in whom bone was harvested from the mandibular ramus, there were fewer postoperative symptoms immediately after the operation than with mandibular symphysis harvesting. Twenty-two of the 29 patients with symphysis grafts experienced decreased sensitivity in the skin innervated by the mental nerve 1 month after the operation. Five of the 24 patients with ramus grafts experienced decreased sensitivity in the vestibular mucosa corresponding to the innervation of the buccal nerve. Eighteen months after the surgery, 15 of the 29 patients in the symphysis group still had some decreased sensitivity and presented with permanent altered sensation. Only one of the patients grafted from the mandibular ramus presented with permanent altered sensation in the posterior vestibular area. No major complication occurred in the donor sites in any of the 53 patients. Conclusion: The results of this study favored the use of the ascending mandibular ramus as an intraoral donor site for bone grafting. [source] | ||||||||||
