Optimizing Wound Care after Surgery of the Head and Neck: A Review of Dressing Materials.

Wound healing is a complex biological process subject to complications that might jeopardize the patient's postoperative care. Appropriately approaching surgical wounds after head and neck surgery positively influences the quality and speed of wound healing and increases patient comfort. A large variety of dressing materials currently exist that allow the care of different types of wounds. Nevertheless, there is limited literature on the most suitable types of dressings after head and neck surgery. The objective of the present article is to review the most commonly used wound dressings, their benefits, indications, and disadvantages, and to provide a systematic approach for wound care within the head and neck. The Woundcare Consultant Society distinguishes wounds into three groups: black, yellow, and red. Each type of wound represents distinctive underlying pathophysiological processes with unique needs. Utilizing this classification along with the TIME model allows a proper characterization of wounds and the identification of potential healing barriers. This evidence-based and systematic approach can facilitate and guide the head and neck surgeon in selecting a wound dressing upon acknowledging their properties, which are herein reviewed and exemplified with representative cases.

Neurovascular structures in the lateral recess of the sphenoid sinus. A computed tomography evaluation / Estructuras neurovasculares en el receso lateral del seno esfenoidal mediante tomografía computarizada

Introduction and objectives Anatomical variations of the lateral recess of the sphenoid sinus and its relations with the adjacent neurovascular structures should be preoperatively evaluated to plan an adequate surgical approach and avoid iatrogenic injuries. This study aims to analyze the patterns of pneumatization of the lateral recess of the sphenoid sinus and their association with the presence of protrusion and dehiscence of the optic canal, carotid canal, vidian canal, and maxillary nerve. Materials and methods A retrospective evaluation of 320 sphenoid sinuses by computed tomography was performed. Studied variables included type of lateral recess, and protrusion, and dehiscence of the optic and carotid canal, and vidian and maxillary nerve. Results The mean age was 45.67±17.43. A total of 55.6% (n=178) of the evaluated sphenoid sinuses corresponded to male subjects. Protrusion of the carotid canal, maxillary nerve, and vidian canal was associated with a type 3 lateral recess pneumatization, while dehiscence of these structures was most commonly observed in a type 2 lateral recess (p=<0.001). Conclusions Protrusion or dehiscence of neurovascular structures surrounding the sphenoid sinus has been associated with the extent of pneumatization of the lateral recess, increasing the risk of intraoperative injury. Preoperative identification of anatomical variations is mandatory to select the best approach for skull base lesions and avoid iatrogenic injuries (AU)

Clinical Benefits of the Utrecht Questionnaire for Aesthetic Outcome Assessment in Rhinoplasty: An Update.

Presently, there is no consensus on which patient-reported outcome measurement (PROM) instrument is best suited to assess the aesthetic outcomes of rhinoplasty. In this regard, at least seven different validated PROMs are available from the literature, each one with advantages and disadvantages.In this article, we review the development, validation, international translation, and clinical application of the Utrecht Questionnaire (UQ). The UQ was developed in 2009 with the idea to be a short and practical tool for the rhinoplasty surgeon to assess the aesthetic outcomes of rhinoplasty. The questionnaire was then validated in 2013. Body image in relation to nasal appearance is quantified with five simple questions on a 5-point Likert scale and a Visual Analogue Scale score. We discuss how the UQ can easily be incorporated and become an important asset in a rhinoplasty practice. Practical benefits, such as its role in the shared decision-making process, patient expectations management, identification of unsuitable patients, avoiding revision surgery, and the evaluation of the surgeon's personal performance curve, are exemplified. Currently, the UQ has been translated and validated in four languages, providing scientific opportunities to generate and compare international data for advances in rhinoplasty. We describe some of the significant scientific contributions of leaders in the field of rhinoplasty that used the UQ.

Deep Neck Infections: Demographic and Clinical Factors Associated with Poor Outcomes.

INTRODUCTION: Deep neck infections (DNIs) are abscesses located in the profound spaces of the neck and constitute one of the most common otolaryngological life-threatening emergencies. The aim of this study is to review the clinical and demographic data of patients with DNI and identify factors associated with prolonged hospitalization, reoperation, and mortality. METHODS: Retrospective review and analysis of 75 patients with DNI admitted from January 2015 to December 2019 in a tertiary referral hospital. RESULTS: Of 75 patients, 50 (66.6%) were males and 25 (33.3%) females. Age ranged from 18 to 91 years with a mean of 41.79 (±15.48). DNIs were odontogenic in 49 patients (65.3%). History of diabetes mellitus (DM) was positive in 26 patients (34.6%). The submandibular space was involved in 57 patients (76%). Streptococcus spp. were isolated in 35 patients (46%). Intubation for airway preservation was needed in 21 patients (28%) and tracheostomy in 6 (8%). Mediastinitis presented in 8 patients (10.67%), with a mortality rate of 62.5% (n = 5). Mean hospital stay was 9.13 days (±7.2). DM (p = 0.016), age (p = 0.001), BMI classification 3, 4, and 6 (p = 0.041), and intensive care unit (ICU) admission (p = 0.009) were associated with a longer stay. Surgical drainage was performed after 1.71 days (±1.65). Surgical reintervention was needed in 6 cases (8%) and was associated with temporal (p = 0.001) and masticator (p = 0.002) space involvement and DM (p = 0.009). Overall mortality was 8% and decreased to 1.5% when mediastinitis was excluded. Mediastinitis (p = 0.001), ICU admission (p < 0.0001), Streptococcus spp. (p = 0.019), and low hemoglobin levels (p = 0.004) were associated with mortality. DISCUSSION/CONCLUSION: DNIs are entities associated with high morbimortality. Mediastinitis and airway obstruction are life-threatening possible complications and should be promptly evaluated. Low HB could be used as a predicting factor for mortality.

"Chronic granulomatous invasive fungal rhinosinusitis associated with SARS-CoV-2 infection: A case report".

INTRODUCTION AND IMPORTANCE: Granulomatous chronic invasive fungal rhinosinusitis (GCIFR) is a rare entity with scarce cases reported mainly in subtropical areas. Its prevalence among individuals with clinical suspicion of fungal rhinosinusitis has been reported in approximately 20% in subtropical populations, unlike North America with a prevalence of 0.5%. It is typically associated with Aspergillus flavus and the presence of noncaseating granulomas or Langerhans giant cells on histopathologic examination. CASE PRESENTATION: We describe a case of a patient with clinical history of recent SARS-CoV-2 infection and development of intense cephalalgia, visual impairment, palpebral ptosis, and limitation of extraocular movements. MRI demonstrated the presence of opacification of paranasal sinuses, and a left intraconal abscess. A surgical endoscopic approach was performed and histopathologic examination revealed frontal GCIFR and maxillary fungus ball. Treatment with IV azoles provided adequate clinical response. CLINICAL DISCUSSION: The spectrum of the fungal rhinosinusitis disease is not clear. However, non-invasive fungal rhinosinusitis is not often found concomitantly with invasive types. GCIFR typically manifests with an indolent and gradual progression at early stages. Advanced stages can exhibit orbital and intracranial involvement leading to visual impairment, frequent relapses, and a poor prognosis. A higher incidence of invasive fungal rhinosinusitis has been reported in patients with SARS-CoV-2 infection despite an unremarkable medical history, associated with immune dysregulation. CONCLUSION: GCIFR is a rare condition with few cases reported in America. Because of its uncommonness, its diagnosis is often delayed leading to increased morbidity and mortality.

Age adjusted normative data for Video Head Impulse Test in healthy subjects.

PURPOSE: This study aims to assess the effect of age in vestibulo-ocular reflex (VOR) gain measured by Video Head Impulse Test (VHIT) and to present normative data of VOR gain, median gain at 40, 60, 80 and 0-100 ms, and gain asymmetry according to decades of life in healthy subjects. MATERIAL AND METHODS: A total of 132 subjects with no previous history of vestibular disorders were enrolled to assess VOR gain by employing VHIT. The test was performed in the X-axis evaluating both horizontal semicircular canals (HSC). The same right-handed operator performed the test in all subjects. RESULTS: The mean VOR gain was higher in the right ear (0.99 ± 0.09) compared to the left ear (0.97 ± 0.08) (p = 0.001). Median gain at 60 ms was 0.92 ± 0.12 in the right HSC and 0.93 ± 0.10 for the left HSC, without significant difference (p = 0.94). A significant decrease of VOR gain occurred with increasing age in the right ear (r = -0.21, p = 0.01). Median gain at 60 ms decreased significantly as age increased in both HSC (right r = -0.17, p = 0.04; left r = -0.23, p = 0.006). No significant differences in VOR gain values were observed when the sample was stratified by age according to the analysis of variance. CONCLUSIONS: A slight but significant decrease in VOR function was observed as age increased for gain and median gain at 60 ms. Larger studies, including patients with central and peripheral vestibular disorders, are needed to assess the clinical implication of this effect when evaluating patients with vestibular disorders.

Sphenoid Sinus: Pneumatization and Septation Patterns in a Hispanic Population.

INTRODUCTION: Pneumatization of the sphenoid sinus (SS) varies widely among different ethnic groups. Information regarding the prevalence and significance of SS variants among Hispanic groups is limited. This study aims to describe and analyze pneumatization and septation patterns of the SS in a Hispanic population. METHODS: A total of 160 paranasal sinus computed tomographies were reviewed by a head and neck-specialized radiologist and 2 otolaryngologists. RESULTS: The postsellar and sellar types were the most frequent patterns of pneumatization observed, with a prevalence of 52.5 and 40%, respectively. Accessory septations were present in 59.4% of the patients. Septa were inserting over the internal carotid artery (ICA) in 43.8% and over the optic nerve in 17.5% of the population. No significant association (p > 0.05) was observed when comparing the different accessory septation patterns among the types of the SS. The frequency of septa inserting on the ICA was significantly higher in postsellar types (p < 0.001). Pneumatization of the anterior clinoid process, pterygoid processes, and greater wing was present in 20, 17.5, and 45.9% of the sinuses, respectively. Onodi cells were encountered in 40% of the sinuses. There were no significant differences in any of the pneumatization and septation variables when compared by gender and age (p > 0.05). DISCUSSION/CONCLUSION: Differences regarding anatomical variants and septations of the SS were observed in our study when compared with findings reported in other ethnic groups. Preoperative assessment of the anatomical variants of the SS in Mexican patients is imperative to select the most optimal surgical approach and prevent iatrogenic injuries to related neurovascular structures.
