CASE DESCRIPTION
A 3-year-old 17.5-kg (38.5-lb) mixed-breed dog was referred for evaluation because of nasal discharge, sneezing, and signs of nasal congestion of approximately 9 months' duration. A diagnosis of nasopharyngeal stenosis (NPS) was made prior to referral.
CLINICAL FINDINGS
Sneezing, bilateral mucopurulent nasal discharge, reduced nasal airflow, stertor, and increased inspiratory effort were noted on physical examination. Results of serum biochemical analysis were within respective reference ranges. Review of CT images of the skull revealed findings consistent with severe bilateral partial osseous choanal atresia and NPS. Retrograde rhinoscopy confirmed membranous NPS.
TREATMENT AND OUTCOME
A ventral rhinotomy was performed; communication between the pharynx and nasal passageway was reestablished by surgical debridement of the caudal border of the palatine bone and vomerine crest and groove, followed by dissection of the membranous NPS and reconstruction of the caudal part of the nasopharynx. A covered nasopharyngeal stent was placed in the newly established nasopharynx. The dog recovered uneventfully but was presented 3 weeks later with recurrent signs; diagnostic findings were consistent with stenosis rostral to the stent. The stenosis was treated with balloon dilation, and a second covered stent was placed rostral to and overlapping the first stent, spanning the stenotic region. Eleven months after this procedure, the dog was doing well.
CLINICAL RELEVANCE
Results for this patient suggested that ventral rhinotomy and covered nasopharyngeal stent placement can be used successfully for the management of osseous choanal atresia in dogs; however, careful attention to preoperative planning and potential complications is necessary.

Review
The American otolaryngologist Eagle was the first to describe styloid syndrome in 1937. Stylohyoid complex is composed of styloid process, stylohyoid ligament and a lesser horn of the hyoid bone. Embriologicaly, these anatomical structures originate from Reichert's cartilage of the second brachial arch. In the general population, the frequency of the elongated styloid process is estimated to be 4%, of which only 4% show clinical manifestations suggesting that the incidence of styloid syndrome is 0.16% (about 16,000 persons in Serbia). The styloid process deviation causes external or internal carotid impingement and pains which radiate along the arterial trunk. Classical stylohyoid syndrome is found after tonsillectomy and is characterised by pharyngeal, cervical, facial pain and headache. Stylo-carotid syndrome is the consequence of the pericarotid sympathetic fibres irritation and compression on the carotid artery. Clinical manifestations are found most frequently after head turning and neck compression. The diagnostic golden standard for styloid syndrome is 3D CT reconstruction. Sagital CT angiography has a leading role in the radiological diagnosis of the stylo-carotid syndrome. Differential diagnosis requires the differentiation of the styloid syndrome from numerous cranio-facio-cervical painful syndromes. If conservative treatment (analgesics, anticonvulsants, antidepressants, and local infiltration with steroids or anaesthetic agents) has no effect, surgical treatment is applied. Styloid syndrome is underrepresented in neurological literature. The syndrome is considered important, because it is clinically similar to many other painful cranio-facial syndromes; it is difficult to be recognized, and the patient should be treated adequately.

Review
Organ preservation regimens that combine chemotherapy and radiotherapy (chemoradiotherapy) are increasingly used as the primary treatment of laryngeal and pharyngeal cancers. Meta-analytic data show a survival benefit with combined modality therapy, but the functional sequelae can be significant. Dysphagia is recognized as a common and often devastating late effect of chemoradiotherapy. This review examines functional outcomes after chemoradiotherapy for laryngeal and pharyngeal cancers, with a particular emphasis on dysphagia. Topics examined include the burden of dysphagia after chemoradiation, pathophysiology of dysphagia, baseline functioning, recommendations to improve long-term function, and voice outcomes.

We aimed to summarize the surgical treatment for pharyngolaryngeal stenosis and discuss prognosis in patients with Behcet's disease. Six cases of pharyngolaryngeal stenosis caused by Behcet's disease were analyzed retrospectively. All underwent surgical treatment for pharyngolaryngeal stenosis after systematic medical treatment. The follow-up time for the 6 patients was between 1 and 12 years. Four of the 6 patients underwent adhesiolysis as their first procedure. Two of these 4 experienced recurrence of stenosis within 6 months and underwent flap repair as their second procedure. The remaining two patients underwent flap reconstruction as their first procedure and maintained good swallowing function. Three of the 6 patients underwent preoperative tracheotomy because of dyspnea. Tracheal decannulation was successful in all patients. None of the patients experienced recurrence after their final surgical procedure and all recovered to a near-normal condition. Pharyngolaryngeal stenosis caused by Behcet's disease is a rare but severe complication; surgical intervention should be considered in patients with dysphagia after systematic medical treatment.

INTRODUCTION
One of the most common complications in the immediate and late postoperative period following total laryngectomy or pharyngolaryngectomy is pharyngocutaneous fistulae (PCF) formation and pharyngoesophageal stenosis (PES), causing significant mortality and morbidity. Since 1978, Montgomery salivary bypass tube (MSBT) has been used to reduce the incidence of PCF and PES. The aim of this retrospective study was to analyze the outcomes of using MSBT both as a tool to prevent PCF and PES and to treat these complications in the postoperative period.
METHODS
Between January 2013 and December 2019, we inserted 109 MSBT in 87 patients with laryngeal/hypopharyngeal cancer treated in the Unit of Otolaryngology of our University Hospital.
RESULTS
Sixty (86.9%) patients healed from complications with primary and secondary placement of MSBT. Seven patients presented a persistence of PCF and 2 presented a recurrence of PES. Secondary placement of MSBT allowed treating successfully 15 (83%) of 18 patients. Only 3 of them presented a PCF at the end of the follow-up period.
CONCLUSION
According to our experience, the MSBT is an affordable, easy to apply and well-tolerated tool. Although it is generally used for PCF treatment, it can also be used intraoperatively for PCF and PES prevention.

Brachycephalic syndrome (BS) is a pathophysiological disorder caused by excessive soft tissue within the upper airways of short-nosed dog breeds, causing obstruction of the nasal, pharyngeal and laryngeal lumen, resulting in severe respiratory distress. As the prevalence of BS appears to be high among some of the affected breeds, there is an urgent need for breeding efforts to improve the health status of those dogs. In the present study, we evaluated correlations between morphometric and other phenotypic characteristics and BS in a population of 69 French bulldogs from Denmark to identify parameters that could serve as a basis for breeding against BS. Furthermore, the genetic variation was monitored to determine whether it would be possible to breed based on these characteristics without simultaneously causing a critical reduction in genetic variation. Six phenotypic characteristics were correlated with the Brachycephalic Syndrome Functional (BSF) score. Among the morphometric risk factors, nostril stenosis (NS) and neck girth (NG) had the highest impact on the BSF score, accounting for 32% and 4% of the variation, respectively. The genetic variation in the population was comparable to other pure breeds, i.e. estimated and observed heterozygosity was 0.60 and the average inbreeding coefficient was 0.01. If only dogs with Grades 1 and 2 NS (no or only mild NS) were selected for breeding the mean BSF score would be reduced significantly. However, it would result in the exclusion of 81% of the population for breeding and this is not prudent. Excluding only dogs with severe stenosis (Grade 4) would exclude 50% of the population without any adverse impact on genetic variation within the population. Although exclusion of dogs with Grade 4 would result in an apparent reduction in the mean BSF score, this reduction is not significant. As NS accounts for 32% of the variation in BSF score, a possible long term strategy to reduce the prevalence of the BS in French bulldogs would seem to be a selection scheme that first excluded dogs with the most severe NS from breeding, gradually moving towards selecting dogs with lower NS grades. According to our findings there is no viable short term solution for reducing the prevalence of BS in the French bulldog population.

BACKGROUND
Goldenhar syndrome is a congenital disease that involves an absence or underdevelopment of structures that arise from the first and second pharyngeal arches and more or less severe extracranial anomalies. A variety of supraglottic malformations may be observed, including mandibular hypoplasia, mandibular asymmetry and micrognathia. Subglottic airway stenosis (SGS), which can cause difficulties in airway management during the perioperative period, is seldom emphasized in literature descriptions of Goldenhar syndrome, but can be clinically significant.
CASE PRESENTATION
An 18-year-old female with a history of Goldenhar syndrome presented for placement of a right mandibular distractor, right retroauricular dilator, and stage I transfer of a prefabricated expanded flap under general anesthesia. During tracheal intubation, the endotracheal tube (ETT) met resistance unexpectantly when attempting to pass through the glottis. Subsequently, we attempted the procedure with a smaller size ETT but again met resistance. With fiberoptic bronchoscope, we found that the whole segment of the trachea and bilateral bronchi were obvious narrow. Given the finding of unexpected severe airway stenosis and the associated risks with proceeding with the surgery, the operation was cancelled. We removed the ETT once the patient was fully awake.
CONCLUSIONS
Anesthesiologists should be aware of this clinical finding when evaluating the airway of a patient with Goldenhar syndrome. Coronal and sagittal measurements on computerized tomography (CT) and three-dimensional image reconstruction can be used to evaluate the degree of subglottic airway stenosis and measure the diameter of the trachea.

JAMA Otolaryngology-- Head & Neck... Jul 2017Targeted laryngoscopy training can be used successfully in de novo learners.
IMPORTANCE
Targeted laryngoscopy training can be used successfully in de novo learners.
OBJECTIVE
To determine the value of targeted laryngoscopy education in interns.
DESIGN, SETTING, AND PARTICIPANTS
This prospective study of fiberoptic laryngoscopy interpretations enrolled 13 participants in an academic hospital setting from August 1 to December 31, 2015. Participants included 10 postgraduate year 1 emergency and otolaryngology interns and 3 board-certified otolaryngology attending physicians.
INTERVENTIONS
Participants viewed 25 selected and digitally recorded fiberoptic laryngoscopies and were asked to rate 13 items relating to abnormalities in the pharynx, hypopharynx, larynx, and subglottis; the level of concern; and confidence with the diagnosis. A laryngoscopy teaching video was then administered to the interns before rating a second set of 25 videos. Improvement in diagnosis and intraclass correlation coefficients (ICC) were calculated for each question and compared between the first and second administration.
MAIN OUTCOMES AND MEASURES
Improvement in correct diagnosis of abnormalities in recorded laryngoscopies.
RESULTS
All 13 participants completed the interventions. The ICCs for all questions were generally low for the intern groups and higher for the attending group. For vocal cord mobility, a preintervention ICC of 0.25 (95% CI, 0.16-0.37) improved to 0.47 (95% CI, 0.36-0.59) among interns after the intervention. The ICCs for vocal cord mobility were higher among attendings for the preintervention (0.89; 95% CI, 0.84-0.93) and postintervention (0.89; 95% CI, 0.83-0.93) assessments. Minimal improvement was observed in intern scores for base of tongue abnormalities, subglottic stenosis, vocal cord abnormalities, level of comfort, level of concern, pharyngeal abnormalities, or laryngeal, pharyngeal, and hypopharyngeal masses.
CONCLUSIONS AND RELEVANCE
Learning of flexible laryngoscopy can be improved with the use of a teaching video; however, additional interventions are needed to attain competence in accurately diagnosing upper airway lesions. Clinicians who seek to perform flexible laryngoscopy require robust training.

We describe an acute, postoperative dysarthria-facial paresis. While the rare stroke syndrome has been described previously, we present an under-described clinical nuance to its presentation with a particularly clear imaging correlation. A 78-year-old, right-handed man with a past medical history of aortic stenosis presented after a transcatheter aortic valve replacement. Immediately postoperatively, no neurological deficits were noted. That evening, he described his speech as "drunken." He was later noted to have a right lower facial droop in addition to the speech change. His speech exhibited labial, lingual, and (to a lesser degree) guttural dysarthria. At the patient's request due to claustrophobia, he received 2 mg of oral lorazepam prior to cranial imaging. Afterwards, he was sleepy but arousable, yet was unable to put pen to paper when asked to write. Right lower facial paresis persisted, but he now demonstrated a right pronator drift, which resolved after 14 h without other evolution to his clinical examination. Brainstem lesions above the level of the pontine facial nucleus may present with central facial paresis contralateral to the lesion. An associated dysarthria may have both labial and lingual features in the absence of tongue or pharyngeal weakness. Our review of reported cases of dysarthria in isolation, dysarthria in combination with facial paresis, and facial paresis finds that all presentations may result from cortical, subcortical, or brainstem involvement. Stroke mechanisms are most commonly thromboembolic or small-vessel-ischemic in either the anterior or posterior circulations.

Treatment of locally advanced laryngeal and hypopharyngeal cancers often requires total laryngectomy with partial pharyngectomy and adjuvant radiotherapy. Dysphagia is common after such aggressive treatment which is often under reported, but adversely affects the quality of life in these patients. The cause for this dysphagia is loss of pharyngeal mucosa, fibrosis, disruption of constrictors and loss of skeletal support to soft tissues. In this study 32 patients treated by laryngectomy with partial pharyngectomy and adjuvant radiotherapy underwent fibreoptic endoscopic evaluation of swallowing at 6 and 12 weeks after completion of treatment. Majority of them had delayed transit of bolus, dryness and edema and 6 of them had pharyngeal stenosis, 2 had fibrotic band and 2 had adynamic pharyngeal segments. These findings were the cause of dysphagia. The frequency of occurrence of the above findings and their association with extent of resection of pharyngeal mucosa and adjuvant treatment have been documented. Bilateral neck dissection, post operative chemotherapy with radiotherapy and use of myocutaneous flap for the reconstruction of neopharynx were found to cause severe dysphagia in our series. Some of these patients benefitted by swallowing therapy, diet modifications and nasogastric feeding. Therefore early identification of cause of dysphagia in these patients and timely intervention to facilitate rehabilitation can improve the quality of life and reduce the long term morbidity in these patients.
