RESUMEN

Inducible laryngeal obstruction (ILO) is a phenomenon of paradoxical upper airway closure during breathing causing respiratory distress and a noisy breathing. It most often appears during maximal exertion but can also be induced by inhalation of irritants, pharyngolaryngeal reflux or stressful situations. It can sometimes be confused with an acute asthma attack. The gold standard investigation is a videolaryngoscopy during ergometry which can confirm the diagnosis, allowing appropriate treatment. The aim of this article is to describe the pathophysiology of ILO and to discuss paraclinical examinations and treatment options.


L'obstruction laryngée induite (ILO) est un phénomène de fermeture paradoxale des voies aériennes supérieures pendant la respiration qui provoque une détresse respiratoire et une symptomatologie bruyante. Elle apparaît le plus souvent pendant un effort maximal mais peut aussi être liée à l'inhalation de produits irritants, à un reflux pharyngolaryngé ou au stress. Elle peut parfois être confondue avec une crise d'asthme en phase aiguë. L'examen de choix est la vidéolaryngoscopie d'effort, qui permet de confirmer le diagnostic et de choisir le traitement approprié. Le but de cet article est de décrire la physiopathologie de l'ILO et de discuter des examens paracliniques et traitements proposés.

RESUMEN

Major congenital anomalies are known to play a role in the management and prognosis of airway obstruction. Most studies assess acquired forms of airway obstruction. Data on congenital or otherwise non-acquired forms of airway obstruction is sparse. In this retrospective, single-institution cohort study, we sought to evaluate and compare the patterns of airway obstruction in children with and without major congenital anomalies, and to assess the impact of management and outcome, irrespective of aetiology. Fifty-five patients were included, 23 with and 32 without underlying major congenital anomalies. Multilevel airway obstruction (usually affecting the nasopharynx, oropharynx, and the trachea) was more common in children with congenital anomalies (91% vs. 41%, p < .001). Consequently, these children required more frequent and earlier surgical management, especially tracheostomy and adenotonsillar surgery.Conclusions: Major congenital anomalies are associated with multilevel airway obstruction and poor functional prognosis. A simple clinical definition considering impact of major congenital anomalies on development and growth may help guide management plans following endoscopic evaluation of the entire airway and flanked by multidisciplinary discussions. What is Known: • Children with major comorbidities display increased disease severity and more prevalent multilevel airway obstruction • Previous studies include both children with acquired and non-acquired forms of airway obstruction; therefore, the actual impact major comorbidities in children with non-acquired causes of airway obstruction remain unclear. What is New: • A total of 42% children in this study population had major comorbidities with and impact on growth and/or psychomotor development, with a higher prevalence of multilevel airway obstruction and worse rates of functional improvement/recovery. • Children with major comorbidities require tracheostomy more often and earlier than those without major comorbidities, and remain tracheostomy-dependent for a longer time.

RESUMEN

The development of vesicles on the pinna and external auditory canal will often correspond to a herpes zoster infection of one of the many nerves innervating the external ear. In case of associated facial paralysis, vertigo or sudden deafness the patient should undergo a thorough neuro-otologic examination and receive appropriate treatment. This article proposes a reminder of the various clinical presentations of herpes zoster oticus with some neuro-anatomical considerations.


L'apparition de lésions vésiculaires au niveau du pavillon de l'oreille et du conduit auditif peut correspondre à une atteinte zostérienne d'un des différents nerfs crâniens et spinaux qui participent à l'innervation sensitive de l'oreille externe. En cas d'association avec une paralysie faciale (syndrome de Ramsay Hunt), de vertiges, d'une atteinte auditive ou d'une autre neuropathie crânienne, le patient devrait bénéficier d'un bilan otoneurologique et d'une prise en charge adaptée. Cet article propose un rappel des différentes formes cliniques d'atteintes zostériennes auriculaires et faciales ainsi qu'un rappel neuro-anatomique.

RESUMEN

Sjögren Syndrome is an autoimmune disorder presenting as Sicca syndrome (dry-eye, dry mouth) and most often multiorgan involvement with various clinical manifestations. The diagnostic criteria defined by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) include biologic, histologic parameters and functional measurements. Part of this workup can be performed by the ENT specialist. It encompasses minor salivary gland biopsy, sialometry, Schirmer lacrymal test and major salivary gland ultrasound. These tests and their performances are described. The growing importance of major salivary gland ultrasound as a follow-up and diagnostic tool is also discussed in this article.


Le syndrome de Sjögren est une maladie auto-immune dont la présentation clinique classique est un syndrome sec oculaire et buccal souvent accompagné d'une atteinte multisystémique aux manifestations cliniques variées. Le bilan diagnostique se compose de différents tests cliniques, histologiques et biologiques définis par l'American College of Rheumatology (ACR) et l'European League Against Rheumatism (EULAR). Une partie de ce bilan peut être effectuée par le médecin spécialiste ORL : la biopsie des glandes salivaires mineures, la sialométrie, le test de Schirmer et l'ultrason des glandes salivaires majeures. Ces tests et leurs performances sont décrits au cours de cet article. L'ultrason des glandes salivaires majeures n'est pour l'heure pas pris en compte dans les critères diagnostiques, mais son rôle dans le bilan et le suivi de la maladie de Sjögren gagne en importance et sera également discuté.

RESUMEN

BACKGROUND AND OBJECTIVES: Precursor lesions of oesophagus adenocarcinoma constitute a clinical dilemma. Photodynamic therapy (PDT) is an effective treatment for this indication, but it is difficult to optimise without an appropriate animal model. For this reason, we assessed the sheep model for PDT in the oesophagus with the photosensitiser meta-(tetra-hydroxyphenyl) chlorin (mTHPC). MATERIALS AND METHODS: Twelve sheep underwent intravenous mTHPC injection, blood sampling and fluorescence measurements. mTHPC's pharmacokinetics was measured in vivo and in plasma by fluorescence spectroscopy. Biopsies of sheep oesophagus were compared to corresponding human tissue, and the mTHPC's biodistribution was studied under fluorescence microscopy. Finally, the sheep oesophageal mucosa was irradiated, 4 days after mTHPC's injection. RESULTS: Histologically, the sheep and human oesophagus were closely comparable, with the exception of additional fatty tissue in the sheep oesophagus. mTHPC's pharmacokinetics in sheep and human plasmas were similar, with a maximum of concentration in the sheep 10 hours after i.v. injection. mTHPC's pharmacokinetics in vivo reached its maximum after 30-50 hours, then decreased to background levels, as in humans under similar conditions. Two days after injection, mTHPC was mainly distributed in the lamina propria, followed by a penetration into the epithelium. The sheep and human tissue sensitivity to mTHPC PDT was similar. CONCLUSION: In conclusion, this model showed many similarities with humans as to mTHPC's plasma and tissue pharmacokinetics, and for tissue PDT response, making it suitable to optimise oesophagus PDT.

RESUMEN

OBJECTIVES: To delineate the various factors contributing to failure or delay in decannulation after partial cricotracheal resection (PCTR) in children. STUDY DESIGN: Case series. SETTING: Academic tertiary medical center. SUBJECTS AND METHODS: A retrospective case review of 100 children who underwent PCTR between 1978 and 2008 for severe subglottic stenosis using an ongoing database. RESULTS: Ninety of 100 (90%) patients were decannulated. Six patients needed secondary tracheostomy. The results of the preoperative evaluation showed grade II stenosis in four patients, grade III in 64 patients, and grade IV in 32 patients. The overall decannulation rate was 100 percent in grade II, 95 percent in grade III, and 78 percent in grade IV stenosis. Fourteen (14%) patients required revision open surgery. The most common cause of revision surgery was posterior glottic stenosis. Partial anastomotic dehiscence was seen in four patients. Delayed decannulation (>1 year) occurred in nine patients. Overall mortality rate in the whole series was 6 percent. No deaths were directly related to the surgery. No iatrogenic recurrent laryngeal nerve injury was present in the entire series. CONCLUSION: Comorbidities and associated syndromes should be addressed before PCTR is planned to improve the final postoperative outcome in terms of decannulation. Perioperative morbidity due to anastomotic dehiscence, to a certain extent, can be avoided by intraoperative judgment in the selection of double-stage surgery when more than five tracheal rings need to be resected. Subglottic stenosis with glottic involvement continues to pose a difficult challenge to pediatric otolaryngologists, often necessitating revision procedures.

RESUMEN

BACKGROUND: Partial laryngectomy techniques are challenging, especially in young patients where function has to be preserved without compromising the oncologic outcome. We present a modified laryngectomy technique indicated for tumors invading one hemicricoid. METHODS: Vertical hemilaryngectomy with reconstruction of neo-glottis by hemi trachea and placement of an endolaryngeal silicon prosthesis for a 21-y old female patient presenting with a synovial sarcoma located on the left arytenoid area. RESULTS: The prosthesis was removed at 6 w with tracheotomy closure at 8w post-op. Patient underwent adjuvant radiotherapy. Functional outcome showed good swallowing without aspiration. Voice was hoarse. At 5 years post-op the patient is free of recurrence presenting only mild dyspnea upon effort. CONCLUSION: Vertical hemilaryngectomy including a hemicricoid is feasible with single stage reconstruction by a hemi-trachea of 4 to 5 rings intussuscepted into the thyroid cartilage. The functional outcome is good considering oncologic safety and avoidance of a permanent tracheostomy. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1708-1716, 2016.

RESUMEN

INTRODUCTION: The efficacy of Gamma Knife surgery (GKS) in local tumor control of non-secreting paragangliomas (PGLs) has been fully described by previous studies. However, with regard to secreting PGL, only one previous case report exists advocating its efficacy at a biological level. CASE REPORT: The aims of this study were: 1) to evaluate the safety/efficacy of GKS in a dopamine-secreting PGL; 2) to investigate whether the biological concentrations of free methoxytyramine could be used as a marker of treatment efficacy during the follow-up. We describe the case of a 62-year-old man diagnosed with left PGL. He initially underwent complete surgical excision. Thirty months after, he developed recurrent biological and neuroradiological disease; the most sensitive biomarker for monitoring the disease, concentration of plasma free methoxytyramine, started to increase. GKS was performed at a maximal marginal dose of 16 Gy. During the following 30 months, concentration of free methoxytyramine gradually decreased from 0.14 nmol/l (2*URL) before GKS to 0.09 nmol/l, 6 months after GKS and 0.07 nmol/l at the last follow-up after GKS (1.1*URL), confirming the efficacy of the treatment. Additionally, at 30 months there was approximately 36.6% shrinkage from the initial target volume. CONCLUSION: The GKS treatment was safe and effective, this being confirmed clinically, neuroradiologically and biologically. The case illustrates the importance of laboratory tests taking into account methoxytyramine when analyzing biological samples to assess the biochemical activity of a PGL. In addition, the identification of methoxytyramine as a unique positive biomarker could designate it for the monitoring of tumor relapse after treatments, including Gamma Knife surgery.

RESUMEN

OBJECTIVE: We sought to assess the long-term outcome of 57 pediatric patients who underwent partial cricotracheal resection for subglottic stenosis. METHODS: Eighty-one pediatric partial cricotracheal resections were performed in our tertiary care institution between 1978 and 2004. Fifty-seven patients had a minimal follow-up time of 1 year and were included in this study. Evaluation was based on the last laryngotracheal endoscopy, the responses to a questionnaire, and a retrospective review of the patient's data. The following parameters were analyzed: decannulation rates, breathing, voice quality, and deglutition. RESULTS: A single-stage partial cricotracheal resection was performed in 38 patients, and a double-stage procedure was performed in 19 patients. Sixteen patients underwent an extended partial cricotracheal resection (ie, partial cricotracheal resection combined with another open procedure). At a median follow-up time of 5.1 years, the decannulation rates after a single- or double-stage procedure were 97.4% and 95%, respectively. Two patients remained tracheotomy dependent. One patient had moderate exertional dyspnea, and all other patients had no exertional dyspnea. Voice quality was found to improve after surgical intervention for 1 +/- 1.34 grade dysphonia (P < .0001) according to the adapted GRBAS grading system (Grade, Roughness, Breathiness, Asthenia, and Strain). CONCLUSIONS: Partial cricotracheal resection provides good results for grades III and IV subglottic stenosis as primary or salvage operations. The procedure has no deleterious effects on laryngeal growth and function. The quality of voice significantly improves after surgical intervention but largely depends on the preoperative condition.

RESUMEN

OBJECTIVES: Partial cricotracheal resection (PCTR) is widely accepted for treating severe paediatric laryngotracheal stenosis (LTS). However, it remains limited to a few experienced centres. Here we report an update of the Lausanne experience in paediatric PCTR performed or supervised by a senior surgeon (Philippe Monnier). METHODS: An ongoing database of 129 paediatric patients who underwent PCTR for benign LTS between March 1978 and July 2012 at our hospital was retrospectively reviewed. Demographic characteristics and information on preoperative status, stenosis and surgery were collected. Primary outcomes were measured as overall and operation-specific decannulation rates (ODR and OSDR, respectively), and secondary outcomes as morbidity, mortality and postoperative functional results. RESULTS: A total of 129 paediatric patients [79 males and 50 females; mean age, 4.1 years (1 month-16 years, median age of 2 years old)] underwent PCTR during the study period. ODR and OSDR were 90 and 81%, respectively. The decannulation rates were significantly superior for single-stage PCTR compared with double-stage PCTR in both ODR and OSDR. Eight patients died postoperatively for reasons unrelated to surgery. Partial anastomotic dehiscence was seen in 13 patients, 9 of whom were successfully treated by revision surgery. Respiratory, voice and swallowing functions were near normal or only minimally impaired in 86, 65 and 81% of patients, respectively. CONCLUSIONS: PCTR is effective and feasible with good ODR and OSDR for highgrade / severe LTS. Glottic involvement and the presence of comorbidities were negative predictive factors of decannulation. Early detection and reintervention of postoperative incipient dehiscence contribute to avoiding the progress to late restenosis; however, voice improvement remains a challenge.

RESUMEN

OBJECTIVE: To investigate the prefabrication of vascularized mucosa-lined composite grafts intended to replace circumferential tracheal defects. DESIGN: Plane grafts composed of ear cartilage and full-thickness oral mucosa were revascularized by the laterothoracic fascia. The use of meshed vs nonmeshed mucosa to improve the epithelial coverage was examined. We also investigated the creation of a vascular bed over the cartilage and the subsequent application of meshed mucosa. Macroscopic aspects, viability, and degree of mucosal lining were analyzed. SUBJECTS: Twenty male New Zealand white rabbits. INTERVENTIONS: Ten animals underwent placement of auricular cartilage under the laterothoracic fascia. Intact (group 1) or meshed mucosa (group 2) was applied over the fascia and protected by a silicone sheet. After 3 weeks, prefabricated grafts were removed for comparison. In 10 other animals, a sheet of perforated cartilage was placed under the laterothoracic fascia. Two weeks later, 5 grafts (group 3) were harvested. The remaining 5 grafts were reopened for mucosal application over the cartilage and revascularized for 3 additional weeks (group 4). RESULTS: Vascularized plane grafts were obtained in all groups. Mucosal lining increased significantly with meshed mucosa (14%-68%; mean, 40%) compared with nonmeshed mucosa (3%-15%; mean, 10%) (P = .008). Induction of a vascular bed over perforated cartilage was achieved, but survival of secondary implanted mucosa was variable. CONCLUSIONS: A reliable technique to prefabricate composite grafts with cartilaginous support and mucosal lining is presented. The use of meshed mucosa significantly improves epithelial coverage.

RESUMEN

OBJECTIVE: To review the presentation and evaluation of laryngotracheoesophageal clefts as well as their treatment modalities, especially endoscopic closure. STUDY DESIGN: retrospective case series. METHODS: All patients treated for laryngotracheoesophageal clefts in our clinic during the last 15 years were included. Analysis of preoperative data, surgical success and functional outcome was performed. RESULTS: A total of 18 patients were included in our study. Cleft distribution was: type I (n=1), type II (n=3), type IIIa (n=5), type IIIb (n=8) and type IVa (n=1). All clefts were closed endoscopically by CO2 laser repair except for two patients who benfited from open surgery (one type I, one type IIIb). 7 of our 18 patients (39%) experienced a complication necessitating reoperation. Surgical treatment of LTEC allowed cessation of feeding tube assistance and artificial ventilation in 47% and 42% of patients respectively. CONCLUSION: Surgical treatement of laryngotracheoesophageal clefts remains a complex procedure with a high rate of morbidity for high grade clefts. Post-surgical difficulties in feeding and breathing are associated with concomitant congenital anomalies. Endoscopic repair is a successful technique for treating up to grade IIIa laryngeal clefts. Further investigation is needed to assess the best approach for treating longer clefts.

RESUMEN

BACKGROUND: The management of pediatric laryngotracheal stenosis (LTS) can be challenging, and laryngotracheal reconstruction (LTR) with cartilage interposition grafting remains the mainstay of surgical treatment for pediatric LTS in most experienced centers. The purpose of this study was to report the results of this procedure in a center where primary cricotracheal resection is frequently performed. METHODS: A retrospective chart review was performed on 45 patients who underwent LTR in our hospital between October 1997 and July 2012. Demographic characteristics and information on the preoperative status, stenosis, and operation were collected. Primary outcomes were measured as overall (ODR) and operation-specific (OSDR) decannulation rates and secondary outcomes as morbidity, mortality, and postoperative functional results. RESULTS: ODR and OSDR were 86.7% (39/45) and 66.7% (30/45), respectively. Re-stenosis was observed in 11/45 (24%) patients, all of whom were endoscopically or surgically treated. Revision surgery was performed in 10 patients, 6 for re-stenosis and 2 for peristomial tracheomalacia. Two children died of mucous obstruction of tracheostomy tube at 3 and 6 months postoperatively (4.4%). Respiratory, voice, and swallowing functions were excellent or good in 86, 75, and 84% of patients, respectively. CONCLUSIONS: LTR for pediatric LTS has high decannulation rates with acceptable morbidity and mortality in selected patients. Most LTR procedures were double-stage for lower grade subglottic stenoses associated with glottic involvement that required stenting. Careful preoperative evaluation and adequate surgical indications are extremely important to achieve high decannulation rates.

RESUMEN

BACKGROUND: The purpose of this article was to provide a review of the literature on shoulder disability after neck dissection. METHODS: A literature review was performed using Ovid Medline and Embase databases. A total of 306 abstracts and 78 full-text articles were reviewed. Forty-two articles were eligible for inclusion. RESULTS: Patients undergoing nerve-sacrifice neck dissections have greater disability and lower quality of life scores than those undergoing neck dissections with the least manipulation (ie, selective neck dissections). Shoulder impairments can still occur in patients undergoing selective neck dissections. Disability typically improves over time in patients undergoing nerve-sparing neck dissections. CONCLUSION: There was significant variability in the literature in terms of the prevalence and recovery of shoulder morbidity after neck dissection. This variability may not just be related to surgical technique or rehabilitation, but also to study design, definitions, and the variability in disability questionnaires used.

RESUMEN

BACKGROUND: Several questionnaires have been used to evaluate shoulder disability after neck dissection. The purpose of this study was to review these measures and highlight their strengths and weaknesses. METHODS: A literature review was performed to identify measures of shoulder disability after head and neck cancer surgery. These measures were evaluated in terms of their methods of development and assessment of their psychometric properties. RESULTS: Seven questionnaires were identified. Several of the other questionnaires have been well developed but have not had their psychometric properties assessed in the head and neck cancer population. Each questionnaire has its strengths and weaknesses. CONCLUSION: The strengths and weaknesses of the shoulder disability questionnaires should be considered when deciding which questionnaire to use. Efforts should be focused on using well-designed questionnaires that have been assessed in this patient population rather than developing or using other questionnaires.

RESUMEN

OBJECTIVES: To evaluate morbidity associated with the radial forearm free flap donor site and to compare functional and aesthetic outcomes of ulnar-based transposition flap (UBTF) vs split-thickness skin graft (STSG) closure of the donor site. DESIGN: Case-control study. SETTING: Tertiary care institution. PATIENTS: The inclusion criteria were flap size not exceeding 30 cm(2), patient availability for a single follow-up visit, and performance of surgery at least 6 months previously. Forty-four patients were included in the study and were reviewed. Twenty-two patients had UBTF closure, and 22 had STSG closure. MAIN OUTCOME MEASURES: Variables analyzed included wrist mobility, Michigan Hand Outcomes Questionnaire scores, pinch and grip strength (using a dynamometer), and hand sensitivity (using monofilament testing over the radial nerve distribution). In analyses of operated arms vs nonoperated arms, variables obtained only for the operated arms included Vancouver Scar Scale scores and visual analog scale scores for Aesthetics and Overall Arm Function. RESULTS: The mean (SD) wrist extension was significantly better in the UBTF group (56.0° [10.4°] for nonoperated arms and 62.0° [9.7°] for operated arms) than in the STSG group (59.0° [7.1°] for nonoperated arms and 58.4° [12.1°] for operated arms) (P = .02). The improvement in wrist range of motion for the UBTF group approached statistical significance (P = .07). All other variables (Michigan Hand Outcomes Questionnaire scores, pinch and grip strength, hand sensitivity, and visual analog scale scores) were significantly better for nonoperated arms vs operated arms, but no significant differences were observed between the UBTF and STSG groups. CONCLUSIONS: The radial forearm free flap donor site carries significant morbidity. Donor site UBTF closure was associated with improved wrist extension and represents an alternative method of closure for small donor site defects.

RESUMEN

PURPOSE OF REVIEW: The article reviews recent significant advances and current applications of the temporoparietal fascia flap (TPFF) in head and neck surgery. RECENT FINDINGS: The recent literature describes a wide span of new applications of the TPFF in many areas. Significant developments and refinements in the reconstruction of orbitomaxillary composite defects and orbital exenteration cavities are reported. The TPFF combined with alloplastic framework is gaining in importance in external ear reconstruction. Innovative prefabricated skin or soft-tissue grafts based on the TPFF are used to restore facial contour or in the reconstruction of complex facial defects. The free TPFF finds a role in laryngotracheal reconstruction as a vascular carrier to support cartilage grafts. SUMMARY: Owing to its reliability and unequalled structural properties, the TPFF still plays a central role in facial reconstruction. Future investigation will likely incorporate the free TPFF as a vascular carrier of bioengineered tissues, such as cartilage and mucosa, for various head and neck indications.

RESUMEN

This article presents a modification of intraoperative external fixation for mandibular reconstruction with free tissue flaps. This technique is indicated when preregistration of the reconstruction plate is not possible due to transmandibular tumor extension. Once standard external fixation has been carried out and prior to segmental mandibulectomy, additional pins are fixed to the connecting rod that delineate the mandibular contour in three-dimensional (3D) space. Following mandibulectomy, these pins allow accurate contouring of the reconstruction plate and improved restoration of mandibular contour, projection, and dental occlusion. A step-by-step description of the technique using models and intraoperative photos is presented. This method of mandibular reconstruction is a simple and time-effective alternative to intraoperative computer navigation and 3D modeling in select cases of oral carcinoma where tumor infiltration of the outer mandibular cortex precludes prebending of the reconstruction plates.
