Head Face and Neck Surgeon Deployment in the New French Role 2: The Damage Control Resuscitation and Surgical Team.

INTRODUCTION: High-intensity conflict is back after decades of asymmetric warfare. With the increase in the incidence of head, face, and neck (HFN) injuries, the French Medical Military Service has decided to deploy HFN surgeons in the new French Role 2: the Damage Control, Resuscitation, and Surgical Team (DCRST). This study aims to provide an overview of HFN French surgeons from their initial training, including the surgical skills required, to their deployment on the DCRST. MATERIALS AND METHODS: The DCRST is a tactical mobile medico-surgical structure with several configurations depending on the battlefield, mission, and flux of casualties. It represents the new French paradigm for the management of combat casualties, including HFN injuries. RESULTS: The HFN's military surgeon training starts during residency with rotation in the different subspecialties. The HFN surgeon follows a training course called "The French Course for Deployment Surgery" that provides sufficient background to manage polytrauma, including HFN facilities on modern warfare. We have reviewed the main surgical procedures required for an HFN military surgeon. CONCLUSION: The systematic deployment of HFN surgeons in Role 2 is a specificity of the French army as well as the HFN surgeon's training.Currently, the feedback from an asymmetric conflict is encouraging. However, it will have to innovate to adapt to modern warfare.

Presbycusis and Fitness to Fly.

BACKGROUND: When a pilot is referred for presbycusis, his flight fitness may be questionable. The objective of this retrospective study was to describe a case series of presbycusis in a pilot population and to discuss the decisions about their flight waivers.METHODS: There were 19 pilots who were referred to the ENT-Head and Neck Surgery Department of the National Pilot Expertise Center. Their medical files were retrospectively examined.RESULTS: Of the 19 patients, 5 did not obtain flight fitness waivers. Among the 14 who received waivers, 7 had no restrictions on their flight fitness.DISCUSSION: Flight fitness was based on the maximum percentage of speech recognition and the slope of the curve for speech recognition in speech audiometry in noise and the follow-up of these findings. The results made it possible to determine a patient's fitness to fly with a waiver, which may be associated with restrictions. In our series, only 5 pilots out of 19 did not obtain a flight fitness waiver. The few published studies on the resumption of flight for patients who had presbycusis and our experience in France with similar waivers in commercial and military aviation suggest that under certain conditions and after relevant cochlear assessment, presbycusis may allow for a safe pursuit of aviation activity.Ballivet de Régloix S, Genestier L, Maurin O, Marty S, Crambert A, Pons Y.

[Congenital cysts and fistulas on the neck in adults]. / Kystes et fistules congenitaux du cou chez l'adulte.

Cervical congenital malformations are relatively common in children. They can also be found in adults. The embryological development of the cervical region is closely related to the branchial clefts. This must be a diagnosis made by elimination; a cervical tumor must evoke the diagnosis of cancer. A cutaneous fistula or a cervical tumor, chronic or recent appearance in an inflammatory context, are the clinical signs. The thyroglossal duct cysts and the second branchial clefts cysts are the most common causes of median and lateral cervical cysts, respectively. Imaging contributes greatly to the orientation and diagnostic evaluation of the extent of the lesions. Treatment is initially based on antibiotic therapy and then on complete surgical excision, away from an infectious episode, the sole guarantee for the absence of local recurrence.

Early Tympanoplasty Using a Synthetic Biomembrane for Military-Related Blast Induced Large Tympanic Membrane Perforation.

Introduction: Blast injuries in modern warfare are common, and tympanic perforation is often found. Spontaneous closures of large perforations that encompass greater than 80% of the tympanic surface are rare. Early closure of the tympanic membrane avoids the immediate infectious risk, which potentially complicates the initial management of these war-wounded patients, and allows for safe and early recovery of military activity. This study compared the outcomes of spontaneous closures and early biomembrane myringoplasty in subjects with large blast injury-induced tympanic perforation following a massive explosion. Materials and Methods: This is a retrospective, observational, cohort study military troops with large barotraumatic tympanic membrane perforation. The study investigates early surgical tympanoplasty versus observation for spontaneous closure. The hearing loss, tympanic perforation closure rate, and closure time were noted. Results: Fourteen patients (19 ears) were referred from May 2008 to April 2017, and 6 patients (9 ears) underwent early myringoplasty. A total of 89% (n = 8) and 100% (n = 9) of the ears exhibited successful sealing of the perforation at one and 6 mo, respectively. In contrast, 60% (n = 6) of the 10 ears (8 patients) without initial myringoplasty did not heal spontaneously at 6 mo, and these ears underwent a delayed tympanoplasty procedure. Notably, patients with early myringoplasty suffered lower conductive hearing loss and fewer functional signs remotely. Conclusion: Early myringoplasty using a biomembrane for blast injury-induced large tympanic perforation is a fast and minimally invasive method to achieve earlier tympanic closure and a higher closure rate for safe recovery of activity. It can be performed under general anesthesia concurrently with surgery for additional body-wide trauma. The deployment of ENT surgeons on the battlefield in the French Army has enabled early management of these patients.

Fishbones in the Upper Aerodigestive Tract: A Review of 24 Cases of Adult Patients.

INTRODUCTION: We present a retrospective study series and discussion of the current literature to discuss the management of fishbones in the upper aerodigestive tract. MATERIALS AND METHODS: From January 2013 to July 2016, all patients referred to our referral center because of a fishbone in the upper aerodigestive tract were analysed. RESULTS: Of the 24 patients, 95% of them reported discomfort in the throat. It was noted that 58% of physical examinations and nasofibroscopy results were normal. Ten fishbones were found in the upper aerodigestive tract. They were removed by foreign body forceps or by endoscopy depending on the location. Foreign body-related complications were not observed. Ten patients with no identifiable fishbone had no symptoms after 48 hours. Other patients, including the 10 patients with the fishbone removed, were asymptomatic after 10 days. CONCLUSION: From our experience, we recommend a systematic nasofibroscopy. If it is normal, the patient is assessed at 48h. The complementary investigation by CT scan and/or oesophagoscopy must be reserved in cases of suspicion of oesophageal localization or complication. Otherwise, rigid or flexible endoscopy may be performed when laryngoscopy is unsuccessful or for the treatment of foreign bodies lodged below this area.

[Complications of sinusitis]. / Complications des sinusites.

The complications of sinusitis are essentially secondary to ethmoidal and frontal sinusitis, occurring in patients weakened, particularly in case of immunodeficiency or anatomical defects. The gravity is due to the risk of spreading infection in intracranial tissues and orbital cavity. The diagnosis is always to discuss any symptomatology resistant to treatment and the appearance of orbital or neurological signs. The scanner and MRI contribute greatly to the orientation and diagnostic evaluation of the extent of the lesions. Treatment is based on prolonged antibiotic therapy and surgery and requires a multidisciplinary approach involving ENT, ophthalmologist, neurosurgeon and anesthesiologist resuscitator.

Facial Nerve Monitoring During Parotidectomy:A Two-Center Retrospective Study.

INTRODUCTION: We present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. MATERIALS AND METHODS: From 2007 to 2012, 128 parotidectomies were performed in 125 patients. Of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2). The primary endpoint was the House-Brackmann classification at 1 month and 6 months. Facial palsy was determined when the House-Brackmann grade was 3 or higher. RESULTS: In group 1, 15 facial palsies were noted; 8 were transient and 7 were definitive. In group 2, 19 facial palsies were noted; 12 were transient and 7 were definitive. At both one and six months after parotidectomy, the rate of facial palsy in reoperation cases was significantly higher in group 1 than in group 2. CONCLUSION: Facial nerve monitoring is a simple, effective adjunct method that is available to surgeons to assist with the functional preservation of the facial nerve during parotid surgery. Although it does not improve the facial prognosis in first-line surgery, it does improve the facial prognosis in reoperations.

Comparison of Penetrating Neck Injury Management in Combat Versus Civilian Trauma: A Review of 55 Cases.

UNLABELLED: The objective was to describe a case series of penetrating neck injuries (PNIs) and compare their management in combat versus civilian trauma. METHODS: From 2012 to 2014, all soldiers and civilians referred to Percy Military Training Hospital for PNI were analyzed. The mechanism of injury, type and site of the lesion, and initial emergency management were noted. RESULTS: Among the 55 patients, 26 were wounded in action, and 29 were civilians. PNIs were commonly stab wounds resulting from an assault. Anatomical zone II, as well as the central neck compartment, was the most affected area. The most affected organ was the larynx. 74% of patients underwent computed tomography angiography (CTA), surgical exploration was performed for 42% of patients, and 33% of patients required intensive care unit monitoring. The differences between the two groups in terms of management were not statistically significant. CONCLUSIONS: The current management is based on clinical examination and CTA and is similar between soldiers and civilians. Surgical exploration is less commonly used than CTA, which is a fast and accurate method to evaluate PNI for stable patients. The classification by compartment seems more relevant than the classification by anatomical zone, particularly in absence of medical imaging.

Specific activation of operculum 3 (OP3) brain region during provoked tinnitus-related phantom auditory perceptions in humans.

The phantom sound perception mechanism by which a sound perception occurs without any external sound source is still enigmatic. According to our previous fMRI study, a small region in the parietal operculum 3 was hyperactivated as a function of tinnitus periodicity in subjects with acoustic trauma tinnitus sequelae. This region was localized in the vicinity of neural correlates of middle-ear tympano-ossicular chain movements due to pressure variations. Disturbed proprioceptors are known to trigger illusory perceptions; therefore, we hypothesized that a disturbance of middle-ear proprioceptors may originate phantom sound perceptions. We designed an fMRI study that aimed to stimulate middle-ear proprioceptors by repetitive vibrations using various rates of click trains. In this study, we report that exposure to specific rates of stimuli for a few minutes at comfortable intensity level in healthy subjects distinctly triggered transient tinnitus-like aftereffects. The fMRI neural correlates of the aftereffects were unequivocally localized in the same parietal region as in acoustic trauma tinnitus sufferers. Our results strongly suggest that a middle-ear kinesthetic/proprioceptive illusion exists at the origin of acoustic trauma tinnitus via a somatosensory pathway encompassing the trigeminal system.

[Pathological link between teeth and maxillary sinus] / Relations pathologiques entre dents et sinus maxillaire

Pathological link between teeth and maxillary sinus. Pathological relationship between the teeth and the maxillary sinus can be explained by their embryological and anatomical relationships. The floor is centered by the apex of antral teeth: premolars and first molars. Any dental disease process may have sinus consequences. Dental caries are the best example. Iatrogenic pathology, including preimplant surgery and benign or malignant tumors are also responsible for sinusitis. Therapeutic for every etiology avoids the complications and sequelae whose forensic incidence remains low.

Relations pathologiques entre dents et sinus maxillaire. Les relations pathologiques entre les dents et le sinus maxillaire s'expliquent par leurs nombreux rapports, tant embryologiques qu'anatomiques. La paroi inférieure du sinus est centrée par les apex des dents dites antrales : les prémolaires et les premières molaires. Ainsi, tout processus pathologique dentaire peut avoir des conséquences sinusiennes. La pathologie carieuse en est le meilleur exemple. La pathologie iatrogène, notamment la chirurgie pré-implantaire, ainsi que les tumeurs bénignes ou malignes sont également responsables de sinusites. Une thérapeutique adaptée à chaque cause permet d'éviter les complications et les séquelles.

Otosclerosis and Fitness to Fly.

BACKGROUND: When an aircrew member is referred for otosclerosis, his flight fitness may be questionable. The objective of this retrospective study was to describe a case series of otosclerosis in an aircrew population and to discuss the decisions about their flight waivers. METHODS: There were 27 aircrew members who were referred to the ENT-Head and Neck Surgery Department of the National Pilot Expertise Center. Their medical files were retrospectively examined. RESULTS: Out of 16 patients who had surgery, 2 did not obtain a flight fitness waiver afterwards. Among the 14 who received waivers, 12 had no restrictions on their flight fitness. Among the nonoperated patients, 1 of 11 did not obtain a waiver. Seven patients were declared medically fit to fly without a waiver and three obtained a waiver. DISCUSSION: Fitness was based on auditory and balance statuses and the follow-up of these findings. A postoperative CT-scan and the operative report were used to determine the quality of stapes surgery. Professional speech audiometry in noise might be as interesting. The results made it possible to determine a patient's fitness to fly with a waiver, which is more or less associated with restrictions. In our series, only 3 aircrew members out of 27 did not obtain a flight fitness waiver. The few published studies on the resumption of flight for patients who underwent surgery and our experience in France with similar waivers in commercial and military aviation suggest that under certain conditions and after relevant vestibulocochlear assessment, stapes surgery may allow for a safe recovery of aviation activity.

Minimally invasive video-assisted thyroidectomy: tips and pearls for the surgical technique.

BACKGROUND: The objectives of this study were first to show principles of the minimally invasive video-assisted thyroidectomy (MIVAT), based on a video highlighting critical steps, and second to discuss tips and pearls to assist surgical teams that would like to start using this technique. METHODS: Based on a video, we described tips and pearls of a MIVAT. RESULTS: MIVAT includes 5 main steps: (1) skin incision and identification of the common carotid artery, (2) dissection and ligation of the upper pedicle, (3) identification of the inferior laryngeal nerve and parathyroid glands, (4) isthmectomy and lobe extraction, and (5) closure. DISCUSSION: Coordination between the surgeon and the 2 assistants is of paramount importance for the performance of MIVAT. Appropriate material is also required. The magnification and tissue contrast emphasizes the identification of the vessels, the superior and inferior laryngeal nerves, and parathyroid glands, on a large-view screen.

Ethmoid sinus osteoma: diagnosis and management.

BACKGROUND: Ethmoid sinus osteomas are uncommon, benign, osteogenic tumors. The purpose of this retrospective study was to describe their usual clinical presentation and to discuss their surgical management. METHODS: The medical records of 25 patients treated for ethmoid osteoma between March 2001 and December 2010 were retrospectively reviewed. RESULTS: The average tumor size was 18.5 ± 14 mm. Only 3 patients were asymptomatic, 14 had a history of frontal sinusitis (complicated with orbital cellulitis in 4 cases), and 4 patients presented with diplopia. An endoscopic approach was performed in 19 cases, a coronal approach in 4 cases, and a combined approach (endoscopic + coronal) in 2 cases. No recurrence was reported. CONCLUSION: Ethmoid sinus osteoma can be asymptomatic and detected incidentally on CT scans, but often causes frontal sinusitis and orbital complications. The endoscopic approach offers the possibility of safe removal with cosmetic advantages compared to coronal approach.

Minimally invasive video-assisted thyroidectomy: Learning curve in terms of mean operative time and conversion and complication rates.

BACKGROUND: The purpose of this study was to evaluate the learning curve for minimally invasive video-assisted thyroidectomy (MIVAT). METHODS: Fifty consecutive patients were prospectively included in groups corresponding to their surgical order (10 patients in each group). RESULTS: The mean operation times between 2 neighboring groups were 33.9 minutes longer in group 1 than in group 2 (p = .01) and 25.8 minutes longer in group 3 than in group 4 (p = .002). The conversion rate for technical difficulties in group 1 was 6% (3 of 50). The definitive complication rate was 2% (1 of 50). CONCLUSIONS: In terms of operative time, 10 patients represented the early stage of the learning curve, and 30 patients represented the number of procedures required to reach an advanced level of skill. Considering the low conversion and complication rates, improved aesthetic results and postoperative course, MIVAT should become a tool in the repertoire of high-volume thyroid surgeons.

Juvenile nasopharyngeal angiofibroma: does the external approach still make sense?

OBJECTIVE: The aim of this study was to review recent management of juvenile nasopharyngeal angiofibroma (JNA) in our institution during the past 10 years and to analyze the shift in surgical paradigm based on the rate of endoscopic approach and Radkowski staging. STUDY DESIGN: Case series with chart review. SETTING: The study was conducted from April 2000 to August 2010 in a tertiary care university hospital (Lariboisière, Paris, France). SUBJECTS AND METHODS: All patients referred for a JNA were included in the study. Medical files and imaging data were retrospectively analyzed. Surgical management was then evaluated for 2 different periods (group 1, n = 31, consecutive patients operated on from April 2000 to June 2005, and group 2, n = 41, from July 2005 to August 2010). RESULTS: Seventy-two patients were operated on, with a mean age of 16.25 years (range, 9-33 years). The rate of the endoscopic approach was significantly higher in group 2 than in group 1 (82.9% vs 45%). Rates of recurrence and complications were similar. Recurrences (ie, residual disease growing and treated by redo) were noted in 6 cases or 8.3% (group 1, n = 3; group 2, n = 3; P > .05). CONCLUSION: Progress in skull base anatomy, instrumentation, cameras, and surgical strategy allows for expansion of the indications for endoscopic removal of JNA. This approach may have a better outcome in terms of blood loss, hospital stay, and local sequelae. Still, an external approach should be considered only for selected cases due to massive intracranial extension or optic nerve or internal carotid artery entrapment by the tumor.

Abnormal cortical sensorimotor activity during "Target" sound detection in subjects with acute acoustic trauma sequelae: an fMRI study.

The most common consequences of acute acoustic trauma (AAT) are hearing loss at frequencies above 3 kHz and tinnitus. In this study, we have used functional Magnetic Resonance Imaging (fMRI) to visualize neuronal activation patterns in military adults with AAT and various tinnitus sequelae during an auditory "oddball" attention task. AAT subjects displayed overactivities principally during reflex of target sound detection, in sensorimotor areas and in emotion-related areas such as the insula, anterior cingulate and prefrontal cortex, in premotor area, in cross-modal sensory associative areas, and, interestingly, in a region of the Rolandic operculum that has recently been shown to be involved in tympanic movements due to air pressure. We propose further investigations of this brain area and fine middle ear investigations, because our results might suggest a model in which AAT tinnitus may arise as a proprioceptive illusion caused by abnormal excitability of middle-ear muscle spindles possibly link with the acoustic reflex and associated with emotional and sensorimotor disturbances.

Mandibular cuniculatum carcinoma: apropos of 3 cases and literature review.

BACKGROUND: Cuniculatum carcinoma is a well-differentiated form of squamous cell carcinoma that shares histologic characteristics with papillary squamous cell carcinoma and verrucous carcinoma. Cuniculatum carcinoma usually occurs on the plantar region, and only 16 cases involving the oral cavity have been described in the literature. METHODS: The authors have reported 3 cases of mandibular cuniculatum carcinoma. All of the patients were in a great deal of pain. Histologic diagnosis was difficult due to the presence of few cellular atypies. Clinical criteria, osseous lysis, and the coexistence of multiple intraosseous well-differentiated, hyperkeratotic papillomatous lesions with few cellular atypies sign the diagnosis. RESULTS: No local recurrence has been reported after treatment with radical surgery alone. CONCLUSION: The diagnosis is often delayed. Although cuniculatum carcinoma displays aggressive behavior locally, lymph node infiltration and metastasis are rare. The therapy of choice is surgical removal with free margins, after which the prognosis is excellent.

[Alarm and detection signs of upper digestive and respiratory tract cancers]. / Signes d'appel des cancers des voies aérodigestives supérieures.

Upper digestive and respiratory tract cancers represent, in frequency, the fourth cancer in the general population. They are responsible of non-specific symptoms. Clinical examination of this anatomical region is difficult for a layman for whom the specific material is not available to diagnose a small tumour The objective of this paper was to make more sensitive the general practictioners about these type of cancers.

Vestibular schwannoma and fitness to fly.

INTRODUCTION: When a pilot is referred for vestibular schwannoma (VS), his or her fitness to fly may be questioned. The objective of this retrospective study was to describe a series of VS cases in a pilot population and to discuss their fitness to fly options. METHODS: Between September 2002 and March 2010, the ENT/Head and Neck Surgery Department of the National Pilot Expertise Center conducted nearly 120,000 expert consultations for 40,000 pilots. We examined the files of 10 pilots who were referred to our 2 national experts for VS. RESULTS: At the time of the expert consultation, hypoacusis was present in nine cases (four with total deafness), tinnitus in one case, and vertigo in nine cases. In our series, only 2 of the 10 pilots experienced a negative impact on their fitness to fly. DISCUSSION: Decisions on fitness to fly were based on several factors: minimally disturbed audition, i.e., less than a 35-dB hearing loss with a good speech discrimination score; good balance, i.e., no reported difficulties; no spontaneous nystagmus recorded on videonystagmography (VNG); no postural deviation; and a normal head-shaking test. The delay and the VS's evolution between diagnosis and expert consultation are important because the selection of a treatment to control VS is critical in minimizing the possible associated complications. When a pilot is referred for VS, his or her fitness to fly is determined by the size of the tumor, balance, auditory status, and the follow-up results of these findings. The complications that may arise from VS treatments must also be considered.
