Dental treatment is often performed under general anesthesia or sedation when an intellectually disabled patient has a heightened fear of treatment or has difficulty cooperating. When it is impossible to control the patient due to the severity of intellectual disability, conscious sedation is not a viable option, and only deep sedation should be performed. Deep sedation is usually achieved by propofol infusion using the target controlled infusion (TCI) system, with deep sedation being achieved at a slightly lower concentration of propofol in disabled patients. In such cases, anesthesia depth monitoring using EEG, as with a Bispectral Index (BIS) monitor, can enable dental treatment under appropriate sedation depth. In the present case, we performed deep sedation for dental treatment on a 27-year-old female patient with mental retardation and severe dental phobia. During sedation, we used BIS and a newly developed Anesthetic Depth Monitor for Sedation (ADMS$^{TM}$), in addition to electrocardiography, pulse oximetry, blood pressure monitoring, and capnometry for patient safety. Oxygen was administered via nasal prong to prevent hypoxemia during sedation. The BIS and ADMS$^{TM}$ values were maintained at approximately 70, and dental treatment was successfully performed in approximately 30 min.

Hemophilia A is a hemorrhagic disease caused by coagulation factor VIII deficiency. In head and neck cancer surgery, especially during a reconstructive one, complications can occur. These include hematomas due to bleeding which can then lead to flap ischemia, necrosis, and impaired wound healing. There are fewer cases of reconstructive surgery in patients with hemophilia A. Here in we report, a reconstructive surgery that involved mass resection, partial glossectomy (right), selective neck dissection (right, Levels I, II, III, IV), and reconstruction at the lateral arm free flap (left) in a 25-year-old man with hemophilia A. The surgery was successfully performed without any complications after pretreatment with Factor VIII concentrate, which has not been reported earlier.

칼돌기 부위에 고통을 느끼는 칼돌기 통증은 흔하지 않은 근골격계 질환으로 전흉부와 상복부, 목, 양측 어깨, 등으로 통증이 방사될 수 있다. 진단에서 중요한 것은 이러한 통증이 칼돌기의 이상에 의해서 발생할 수 있다는 것을 임상적으로 알고 있어야 한다는 것이다. 2 증례의 칼돌기 통증 환자를 경험하였는데, 칼돌기 부위를 가볍게 누르면 전흉부와 상복부의 통증이 반복적으로 재생산될 때 진단하였다. 수년간 칼돌기 통증으로 고통 받아 왔던 첫번째 증례 환자에서는 칼돌기 제거수술을 하였고, 두번째 증례 환자에서는 국소마취제를 주사하여 치료하였다.

Objective : Development of diagnostic tools has resulted in early detection of thoracic disc herniations[TDH] even when the herniated disc is soft in consistency. In some of the cases, it is considered better not to opt for surgical treatment due to the unduly high morbidity and potential complications associated with conventional approaches. The authors have applied percutaneous endoscopic thoracic discectomy[PETD] technique to soft TDHs in order to avoid the morbidity associated with conventional approaches. Methods : Eight consecutive patients [range, 31 to 75 years] with soft lateral or central TDH [from T2-3 to T11-12] underwent PETD between May 2001 and June 2004. The patient was positioned in a prone position with intravenous sedation and local anesthetic infiltration. The authors introduced a cannula into the thoracic intervertebral foramen using endoscopic foraminoplasty technique. Discectomy was performed with mechanical tools and a laser under continuous endoscopic visualization and flu oroscopic guidance. Functional status was assessed preoperatively and postoperatively using the Oswestry Disability Index[ODI]. Results : The mean ODI scores improved from 52.8 before the surgery to 25.8 at the final follow-up. In cases of myelopathy, long tract signs showed improvement. The mean operative time was 55 minutes, and no patient required conversion to open surgery. Conclusion : The technique allows a smaller incision and less morbidity. Soft TDH is amenable to this minimally invasive approach in selected patients with myeloradiculopathy.

The diagnosis of chronic abdominal pain due to abdominal cutaneous nerve entrapment can be elusive. Tenderness in patients with abdominal pain is naturally assumed to be of either peritoneal or visceral origin. Studies have shown that some patients suffer from prolonged pain in the abdominal wall and are often misdiagnosed, even after unnecessary and expensive diagnostic tests, including potentially dangerous invasive procedures, and treated as having a visceral source for their complaints, even in the presence of negative X-ray findings and atypical symptoms. Abdominal cutaneous nerve entrapment syndrome is rarely diagnosed, which is possibly due to failure to recognize the condition rather than the lack of occurrence. The accepted treatment for abdominal cutaneous nerve entrapment syndrome is a local injection, with infiltration of anesthetic agents coupled with steroids. Careful history taking and physical examination, in conjunction with the use of trigger zone injections, can advocate the diagnosis of abdominal cutaneous nerve entrapment and preclude any unnecessary workup of these patients. Herein, 3 cases of abdominal cutaneous nerve entrapment syndrome, which were successfully treated with local anesthetics and steroid, are reported.

Hyperhidrosis, one of the abnormalities in autonomic nervous system, has been treated with dermatologic principles or thoracic sympathectomy via conventional axillary thoracotomy or dorsal spinal approach. But these techniques were rather ineffective or invasive. Recently, VATS is widely applied in thoracic surgical area, and hyperhidrosis is not the exception of these cases.From May 1993 to August 1994, 30 patients with bilateral palmar hyperhidrosis underwent bilateral thoracic [T2, T3 sympathectomy with thoracoscopic surgery at Seoul National University Hospital. There were 20 men and 10 women and the mean age was 23.0 years.Mean operating time was 115 min and there was no thoracotomy conversion. Operative complications were anesthetic overdose in 1, Horner`s syndrome in 1, and small amount of residual pneumothorax in 6. Mean postoperative hospital stay was 2.3 days [range from 1 to 4 days and postoperative analgesics were required in 17 cases with a single dose.Sweating amount was measured in 12 patients, showing significantly decreased amount from 284.5 mg preoperatively to 18.9 mg postoperatively in 5 minutes [p=0.004 . There was no recurrence during mean 6 months follow up. Twenty two patients [73.3 % complained moderate compensatory hyperhidrosis on the trunk.In conclusion, all patients were greatly satisfied with those results including no more palmar sweating, less pain, better cosmetics, short hospital stay. In addition, recent use of sweating amount measurement and intraoperative temperature monitoring could make this technique more accurate, so we easily applied thoracoscopic sympathectomy with minimal risk.

Objectives: Appropriate and accurate local anesthetic (LA) techniques are indispensable in the field of oral and maxillofacial surgery to obtain a satisfactory outcome for both the operating surgeon and the patient. When used alone, the inferior alveolar nerve block (IANB) technique requires supplemental injections like long buccal nerve block for extraction of mandibular molars leading to multiple traumatic experiences for the patient. The aim of this study was to anesthetize the inferior alveolar, lingual, and long buccal nerves with single-needle penetration requiring a minimal skillset such as administering a conventional IANB through introduction of the Benny Joseph technique for extraction of mandibular molars. Materials and Methods: This was a prospective study conducted in the Department of Oral and Maxillofacial Surgery, Kunhitharuvai Memorial Charitable Trust (KMCT) Dental College, Calicut, India. The duration of the study was 6 months, from June to November 2017, with a maximum sample size of 616 cases. The LA solution was 2% lignocaine with 1:100,000 adrenaline. The patients were selected from a population in the range of 20 to 40 years of age who reported to the outpatient department for routine dental extraction of normally positioned mandibular right or left first or second molars. Results: Of the 616 patients, 42 patients (6.8%) required re-anesthetization, a success rate of 93.2%. There were no complications such as hematoma formation, trismus, positive aspiration, and nerve injuries. None of the cases required re-anesthetization in the perioperative period. Conclusion: The Benny Joseph technique can be employed and is effective compared with conventional IANB techniques by reducing trauma to the patient and also requires less technique sensitivity.

Background: Nitrous oxide (N₂O) is used in surgery and dentistry for its anesthetic and analgesic effects. However, neurological and psychiatric manifestations of N₂O abuse have been increasingly reported among Korean adults. The aim of this study was to demonstrate laboratory findings of N₂O abuse in Korean patients. Methods: Patients diagnosed with N₂O-induced neuropathy or myelopathy from August 2018 to December 2019 were enrolled. Their clinical presentations and laboratory and imaging findings were analyzed. Results: Sensory changes and limb weakness were present in nine of the enrolled patients. The laboratory findings revealed that seven patients had high homocysteine levels and five had high methylmalonic acid levels in their blood. Nerve conductions studies indicated that axonal neuropathy was present in four cases and longer F-wave and Hoffman's-reflex latencies were present in two cases. Signal changes in cervical spine imaging occurred in five patients, while two had normal results. Conclusions: Chronic N₂O abuse can cause neurological damage or psychiatric problems. Because N₂O is illegal for recreational use in Korea, patients tend to hide their history of use. Even though the spinal imaging results were normal, clinicians should consider the possibility of N₂O use, and further electrophysiological tests should be applied for precise evaluations.

Background Cleft treatment is frequently performed in Indonesia, mostly in charity missions, but without a postoperative protocol it is difficult to establish the risks and complications of cleft treatment. The present study was designed to give an overview of current cleft lip and palate treatment strategies in Indonesia and to assess the complication rates during and after surgery. Methods This prospective study evaluated anesthetic, intraoperative surgical, and short-term postoperative complications in patients undergoing primary, secondary, or corrective surgery for cleft lip and palate deformities. The population consisted of 98 non-syndromic cleft patients. The main anesthetic complication that occurred during general anesthesia was high blood pressure, whereas the main intraoperative surgical complication was excessive bleeding and the main early postoperative complication was extremely poor wound hygiene. Results In this study, there were no cases of perioperative or postoperative mortality. However, in 23 (23.4%) of the 98 operations performed, at least one perioperative complication related to anesthesia occurred. The intraoperative and early postoperative complications following cleft lip and/or palate were assessed. There was a significant difference in the complication rate between procedure types (χ²=0.02; P<0.05). However, no relationship was found between perioperative complications related to anesthesia and the occurrence of postoperative complications (χ²=1.00; P>0.05). Nonetheless, a significant difference was found between procedure types regarding perioperative complications and the occurrence of postoperative complications (χ²=0.031; P<0.05). Conclusions Further evaluation of these outcomes would help direct patient management toward decreasing the complication rate.
