Young male children are more likely than adults to sustain dog bite injuries, and up to 80% of these occur in the head and neck region [1]. Timely assessment of these injuries and appropriate decisions for surgical exploration can prevent further insult. One of the most feared complications of neurosurgical procedures in the sitting position, we present the case of a venous air embolism (VAE) in the prone position during repair of a cranial vault injury from a dog bite in a 14- month-old. Informed consent was obtained from the patient's family to publish this letter to the editor.

AbstractHydrogen peroxide (H2O2) irrigation is commonly utilised in neurosurgical and non-neurosurgical procedures for its bactericidal and haemostatic effects. Tension pneumocephalus and venous air embolism are potentially disastrous neurological complications mostly seen after intracranial surgery in sitting position and trauma. We present a case of oxygen embolus and tension pneumocephalus after H2O2 irrigation during craniotomy in supine position.

Dog bite-related wounds seem to have become a common problem, especially when they relate to the head and neck region. According to Overall and Love, up to 18 per 1,000 people sustain a dog bite every year, of whom 3 need medical attention. Approximately 1 to 2% of bite injuries require hospitalization of the victims. Most of the lacerations are found in the upper lip and the nose regions and they are classified according to severity and concomitant damage to other organs. Bite wounds are considered “dirty” wounds and are prone to infection. When dealing with bite wounds, there is always an indication for antibiotic treatment. Broad-spectrum antibiotics like amoxicillin-clavulanate and/or moxifloxacin cover most of the pathogenic flora and should be administered in every bite wound case at risk of infection. This article would like to present a medical record review: a retrospective analysis of all bite wounds sustained in the head and neck region, treated at the University Hospital of Leuven over the past 20 years. Furthermore, it provides an overview of the current literature and its standings on the treatment of dog bite injuries in the maxillofacial region. We assessed both surgical and medical treatment options, as well as primary management, which includes infection prevention strategies, closure management, and additional vaccination requirements. Secondary management or scar revision methods will be mentioned. After conducting a UZ Leuven database search using keywords such as “dog,” “dog bite,” “face,” “head,” “lip,” and others, 223 patients were included. Age at the time of injury, location of the injury, treatment method used, and whether secondary infection was present or not were documented. All patients have been divided in age groups. We concluded that 21.52% was 5 years old or younger. Almost half of our patients (49.33%) were 18 years old or younger. Of all patients, 79 were hospitalized (35.43%). Primary closure was the treatment of choice. In 141 patients, the wounds were closed primarily (63.23%), resulting in only 2.24% reported secondary infections. Only one fatality was reported in our center over the course of 20 years (0.45%), a 6-year-old girl who had been attacked by her father's Rottweilers. Most patients who sustained dog bite injuries in the head and neck region seem to be children, specifically toddlers. Due to their height, it is possible they are more prone to dog bite injuries in the head and neck region. It is essential to optimize management of these injuries due to the impact they have on patients. This article provides the epidemiological data and clinical outcome of the approach at our center.

Background Venous air embolism has been reported to occur in 23-45% of patients undergoing neurosurgical procedures in the sitting position. If venous air embolism occurs, a patent foramen ovale (PFO) is a risk factor for paradoxical air embolism and its sequelae. Preoperative screening for a PFO is therefore recommended by some investigators. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (c-TEE). Contrast-enhanced transcranial Doppler ultrasonography (c-TCD) and contrast-enhanced transthoracic echocardiography (c-TTE) are noninvasive alternative methods, but so far there are no studies as to their diagnostic validity in neurosurgical patients. Methods The sensitivity and specificity of c-TCD and c-TTE in detecting a PFO were determined in a prospective study using c-TEE as the reference standard. Preoperative c-TCD, c-TTE, and c-TEE studies were performed during the Valsalva maneuver after intravenous echo-contrast medium (D-Galactose, Echovist-300, Schering AG, Berlin, Germany) was administered in 92 consecutive candidates (47 men and 45 women; mean age, 51 yr; range, 25-72 yr) before neurosurgical procedures in the sitting position. Results A PFO was detected in 24 of the 92 patients (26.0%) using c-TEE. c-TCD correctly identified 22 patients, whereas c-TTE only correctly identified 10. This corresponds to a sensitivity of 0.92 for c-TCD and 0.42 for c-TTE. The negative predictive value was 0.97 for c-TCD compared with 0.83 for c-TTE. The prevalence of a PFO in patients with a posterior fossa lesion was 27%, and in the group with cervical disc herniation was 24% as detected by c-TEE. The incidence of intraoperative venous air embolism was 35% in cases of cervical foraminotomy and 75% in posterior fossa surgery as detected by c-TEE. Conclusions c-TCD is a highly sensitive and highly specific method for detecting a PFO. Because c-TCD is noninvasive, it may be more suitable than c-TEE for routine preoperative screening for a PFO. C-TTE is not reliable in detecting a PFO.

Abstract Background: Patients undergoing neurosurgical procedures in the posterior cranial fossa can be placed in different positions: the semi-sitting position or the supine position. The major risk of the semi-sitting positioning is venous air embolism (VAE). However, VAEs may also occur in the supine position.Objective: In a prospective study, we investigated the incidence of VAE based on the positioning of the patients (trial registration 553/2013BO1).Methods: In a single-center study with 137 patients, we prospectively evaluated the occurrence of VAEs in patients in the supine and semi-sitting position over the period from January 2014 to April 2015. All patients were monitored for VAE by the use of a transesophageal echocardiography (TEE).Results: 50% of all participating patients experienced a VAE (with 56% of these patients undergoing surgery in the semi-sitting position and 11% in the prone position). 86% of the VAEs were just detected by the use of a TEE. We only observed VAEs with a decrease in EtCO2 in the semi-sitting position. However, none of the patients had any hemodynamic changes due to the VAE. We found that surgeries in patients with a preexisting intracardial shunt such as a patent foramen ovale (PFO) less likely resulted in VAEs (42% vs. 58%).Conclusion: The semi-sitting position with TEE monitoring and a standardized protocol, including a deep central venous line is a safe and advantageous technique, taking also account of a significant rate of VAEs. VAEs also occur in the supine position, however, less frequently.

Tumors in the posterior fossa can be done in lateral, supine, prone, sitting and in park bench positions. Depending on the exact position of the lesion and the technical preference of the surgeon, sitting position may be preferred. Sitting position grants best possible access to deeper structures with minimal retraction. However, maintenance of anaesthesia in this position for long duration pose some serious challenges to the anaesthesiologist including high risk of venous air embolism (VAE), hemodynamic instability and respiratory disturbances. Here, we present a case report of a 36year old male diagnosed with pineal gland space occupying lesion (SOL), operated in the sitting position under general anaesthesia. We discuss about anaesthetic management and possible complications that can be encountered.

<p class="abstract">Extracranial schwannomas in the head and neck region are rare neoplasms. The tumours often present as asymptomatic, slowly enlarging lateral neck masses. Though the computed tomogram criteria for differentiating vagal and sympathetic chain schwannoma is acceptable in most cases, but rarely the clinician may be misled in very large schwannoma of sympathetic chain where determination of the nerve of origin may be impossible until surgical exploration.</p>
