We aimed to assess the satisfaction level of patients with the outcome of genioplasty and the influential parameters in this respect.

This retrospective study was conducted on 70 patients between 18 to 59 years, who underwent genioplasty in the Oral and Maxillofacial Surgery Department at Shariati and Sina Hospitals, Tehran, Iran, between 2010 and 2020. Patient records were evaluated and a questionnaire was filled out over the phone to assess the influential parameters on the satisfaction level of patients with the outcome of genioplasty. Data were analyzed by PASS 11 (alpha=0.1).

Seventy patients were evaluated including 56 (80%) females and 14 (20%) males. Forty patients (52.6%) had no complaint with regard to the outcome of genioplasty. Postoperative chin deviation (not correcting the initial complaint) (10.52%), postoperative pain in the chin area (10.52%), and lower lip paresthesia (9.21%) were the most common patient complaints. The minimum and maximum satisfaction scores were 22 and 80, respectively. Number of follow-up sessions had a significant effect on satisfaction with the outcome of genioplasty (P=0.076). Patients who underwent advancement genioplasty alone had the highest level of long-term satisfaction with the outcome while those who underwent setback genioplasty alone had the lowest level of long-term satisfaction.

Advancement genioplasty had the highest rate of patient satisfaction, and chin asymmetry in the frontal view was the most common patient complaint after genioplasty.

 Intramedullary ependymoma (IE) is adults' most common intramedullary spinal tumor. Tumors usually extend one to eight segments in the cervical region. In this case report, we reported a patient with massive IE spanning from the fourth ventricle to the T4 segment of the spinal cord, which surgically treated with laminectomy from occiput to T4

 A 42-year-old man who is a known case of IE with progressive upper extremities paraesthesia and gait disturbance. Four years ago he refused surgery and presented with dysphagia. The patient's MRI demonstrated an intramedullary spinal cord tumor extending from the fourth ventricle to T4.

 massive spinal ependymoma is a rare, benign, slow-growing tumor, and patients present symptoms years before diagnosis. Upon confirmation of the diagnosis, the tumor must be surgically removed.

Paresthesia can result from some post-endodontic problems, including bacterial infections or mishaps which occur during the cleaning, shaping, and filling of the root canal. There are pharmacological and instrumental methods for the treatment of paresthesia; however, if presenting symptoms are suggestive of nerve injury, surgical approaches, such as intentional replantation, could be considered. In this case report study, we treated paresthesia that had occurred after endodontic treatment using intentional replantation. This case report describes the use of intentional replantation of a mandibular premolar as a successful technique to treat paresthesia involving the lower lip.

Heavy metals, such as lead can cause optic neuropathy. Optic disc neuropathy due to lead intoxication has previously been reported. We report a rare case of lead toxicity-induced optic neuropathy presenting with bilateral hemorrhagic optic disc swelling. Case Report: The patient was a 42-year-old man with a history of chronic oral opium use, who had a gradually progressing blurred vision in both eyes over 40 days, with ataxia, paresthesia, and a toxic level of serum lead. He had been treated with lead chelators for lead poisoning. His color vision was impaired in both eyes. Humphrey’s visual field test revealed double arcuate scotoma with enlargement of the blind spot. Funduscopy revealed bilateral optic disc swelling, which was confirmed on optical coherence tomography and fluorescein angiography.

In cases of optic disc edema, a comprehensive history should be taken to detect the cause. Further, in cases of chronic oral opium use, lead toxicity should be considered.

The mental nerve is a sensory nerve which traverses through mental foramen to innervate the lower lip, chin skin and the mandibular labial gingiva. Interestingly, it’s variant such as the accessory mental foramen (AMF) was described as an unusual finding in the recent literature. Hereby, we reported a patient who was operated to treat the mandibular bisphosphonate-related osteonecrosis of the jaw (BRONJ) lesion. Intraoperatively, an accessory mental foramen was detected posterior to the main foramen and nerve, on the right side of the mandible. This case report highlighted the necessity for proper radiological and clinical evaluation of mental foramina in order to avoid nerve injury and postoperative paresthesia. The review of the literature and the clinical findings were also discussed in this article.

Widespread use of dental implants in the past 15 years has resulted in an increase in complications associated with implant surgeries. The aim of the present study was to determine the frequency of lower lip paresthesia in patients receiving implant-supported mandibular overdentures.

In this descriptive, cross-sectional study, 63 patients receiving implant-supported mandibular overdentures were evaluated. For clinical examination, the two-point discrimination test (2DP) was used before surgery and at 1-, 3- and 6-month postoperative intervals. Data was analyzed using descriptive statistical tests and chi-square test.

The results showed frequency rates of 19%, 4.8% and 4.8% for lower lip paresthesia at 1-, 3- and 6-month postoperative intervals. At 1-month postoperative interval, female patients exhibited a significantly higher rate of paresthesia compared to male patients (P = 0.035).

Lower lip paresthesia was highly prevalent (19%) one-month after implant surgery; however, its frequency decreased over time. After 3 months, the frequency of paresthesia decreased by about 3 quarters (4.8%) and remained constant until 6 months after surgery. During the 1-month period after surgery, female patients had a high rate of paresthesia compared to male patients.

Orofacial paresthesia is due to trauma to the neural structure of a particular nerve. In dentistry alterations caused by nerve damage in most cases are presented with transient symptomatology. However, it has been agreed by several authors that persistent inferior alveolar sensory aberrations for more than 6 months leave some degree of disability or are considered permanent. The objective of the present study is to report the clinical case of a young patient submitted to low-level laser therapy for the treatment of paresthesia of the inferior alveolar nerve after removal of a complex odontoma in the posterior region of the mandible.

Twenty-four hours after the surgical procedure the patient started the low-level laser therapy with the following parameters: 100 mW of potency, 140 J/cm² of energy density, 4 J of energy per application point, 40 seconds of application per point and 0.028 cm² of spot area. For this particular case, the technique of alternation of laser wavelengths was used, in the first session of which visible red of 660 nm was applied, followed by near-infrared of 808 nm and so on.

In the first session, the score on the visual analog scale (VAS) was “3”. In the tenth and last sessions, the patient reported a VAS “9”.

It seems that the early initiation of the low-level laser therapy favors a better outcome in cases like the one presented in this paper. The technique of alternation of laser wavelengths between sessions seems to have some role in the outcome possibly because of the constant stimulation of different chromophores along the treatment course. These two factors need further confirmation and validation through randomized clinical trials.

Neurosensory disturbances following orthognathic surgery, especially sagittal split ramus osteotomy are quite common. Furthermore improving the injuries to the inferior alveolar nerve following ramus osteotomy is still a challenge. This study aims to evaluate the influence of low-level laser therapy (LLLT) on the improvement of neurosensory disturbance following sagittal split ramus osteotomy. This randomized, double- blinded clinical study was executed in a university-affiliated hospital, Tehran, Iran, during January 2017 and March 2018. Patients underwent sagittal split ramus osteotomy (SSRO) divided into case and control groups. Ten sessions of laser irradiation of 810 nanometers wavelength and power of 70 mW were rendered for eight minutes in the case group, while the patients in the control group were not irradiated. Thermal test, mechanoreceptor sensory tests, and satisfaction of the patients were evaluated during follow up examinations. Mapping of the affected skin area was marked to assess the healing process of the nerve damage. A total of 40 patients were included in the current study followed for a 12-month period. Statistical analysis of extracted data from the two-point discrimination test showed the significant better response of mechanoreceptors among the case group patients rather than the control ones (P value = 0.035). Marking the hyposthetic skin area in the patients that experienced laser therapy demonstrated that almost all of them manifested less sense on the vermilion area (85% in the case group versus 15% in the control group). Despite the control group patients whom on the mental foramen area significantly more paresthesia was experienced. In conclusion, low-level laser therapy following sagittal split osteotomy may be helpful in faster recovery of nerve injuries and higher satisfaction of the patients.

Neurosensory disorders after implant insertion are one of the main concerns in implant treatments. Neurosensory disorders can be driven by different factors including the contact of the implant with the nerve, pressure of edema, hematoma, scar, or dental injections. This study aimed at investigating the distance between the implant and the inferior alveolar nerve (IAN) and its impact on neurosensory disorders. In this descriptive study, panoramic radiographs were taken from 100 patients experiencing neurosensory changes after 10 days of implantation. The patients were reassessed 4 weeks later, and the distance (mm) between the implants and the IAN was measured. Data were analyzed using descriptive statistics. All patients experienced neurosensory changes 10 days after implantation. Four weeks after surgery, 82 patients healed: the distance between the implants and the IAN was 1-2 mm in 16 patients and 2 mm in 66 patients. In 18 patients, neurosensory changes persisted; in this group, the distance between the implants and the IAN was less than 1 mm in 11 patients, 1-2 mm in 6 patients, and more than 2 mm in 1 patient. The results indicated that the chance of healing of neurosensory changes is significantly correlated with the distance between the implant and the IAN (P<0.01). This correlation was not significant with respect to age or gender (P<0.9). It seems that the lesser is the distance between the implant and the IAN, the lower is the chance of healing of neurosensory changes.

Mental neuropathy is a sensory neuropathy characterized by hypoesthe-sia or paresthesia of the chin and lower lip. It can be a symptom of a latent malignant disease.
This report presents a case of a 34-year-old woman with a history of breast cancer who complained of severe pain and numbness of the right lower lip. We reviewed numerous reliable articles (through PubMed and Google Search) in relation to mental neuropathy and its possible causes.
Given that the reports of mental neuropathy have often been associated with malignancies, patients that complain of sensory impairment and numbness of the mental region should be examined carefully.

Vitamin B12 plays a role in hematopoiesis, neuronal functions, the synthesis of myelin and epithelium, and the mucosal functions of the gastrointestinal system, so patients with vitamin B12 deficiency may complain of a variety of symptoms.
This study aimed to investigate the association between vitamin B12 levels and clinical symptoms in children and adolescents.
Patients visiting the pediatric outpatient clinic for any reason between April 1 and September 30, 2014 were enrolled in the study. Patients with active infectious diseases, with chronic diseases, or who had any disease or were taking any medications causing vitamin B12 deficiency were excluded from the study. The patient’s complaints were recorded. Each patient’s serum vitamin B12, 25-OH vitamin D, folic acid, and complete blood count were measured in addition to routine tests.
A total of 524 patients who were 8.3 ± 4.2 years old (2.6 months - 15.3 years), which consisted of 272 females (51.9%) and 252 (48.1%) males, met the inclusion criteria. The vitamin B12 level was less than 200 pg/mL in 166 (31.7%) of these patients and was less than 300 pg/dL in 302 (57.6%) of these patients. Vitamin B12 level was not associated with any complete blood count parameters except MCV. The patients with vitamin B12 deficiency were also 25-OH vitamin D deficient (P With vitamin B12 deficiency defined as a vitamin B12 level

A 56-year-old woman with hands paresthesia referred to the physical medicine and rehabilitation Clinic of Imam Khomeini Hospital. Based on physical examination and electrodiagnosis, the patient had bilateral moderate carpal tunnel syndrome with greater intensity in the right side. Wrist splint and acupuncture were prescribed for the patient. 20 sessions of acupuncture were done every other day. At the end of treatment, the patient’s clinical symptoms and electrodiagnostic findings improved, and there was only mild carpal tunnel syndrome in her right hand. It seems that acupuncture can be an effective treatment for carpal tunnel syndrome. Considering its few complications, acupuncture can be used to treat mild to moderate carpal tunnel syndrome.

Paresthesia is a burning or prickling sensation or partial numbness, resulting from neural injury. The symptoms can vary from mild neurosensory dysfunction to total loss of sensation in the innervated area. Only a few cases have described apical periodontitis to be the etiological factor of impaired sensation in the area innervated by the inferior alveolar and mental nerves. The aim of the present paper is to report a case of periapical lesion-induced paresthesia in the innervation area of the mental nerve, which was successfully treated with endodontic retreatment.
