Role and Management of a Head and Neck Department during the COVID-19 Outbreak in Lombardy

The recent Italian outbreak of coronavirus disease 2019 led to an unprecedented burden on our health care system. Despite head and neck\u2013otolaryngology not being a front-line specialty in dealing with this disease, our department had to face several specific issues. Despite a massive reallocation of resources in the hospital, we managed to keep the service active, improving safety measures for our personnel, specifically during common otolaryngologic maneuvers known to produce aerosols. Furthermore, we strived to maintain our teaching role, giving residents an inclusive role in managing the response to the emergency state, and we progressively integrated our inactive specialists into other service rotations to relieve front-line colleagues\u2019 burden. Specific issues and management decisions are discussed in detail in the article

Masseteric-facial nerve neurorrhaphy: results of a case series

OBJECTIVE: Facial palsy is a well-known functional and esthetic problem that bothers most patients and affects their social relationships. When the time between the onset of paralysis and patient presentation is less than 18 months and the proximal stump of the injured facial nerve is not available, another nerve must be anastomosed to the facial nerve to reactivate its function. The masseteric nerve has recently gained popularity over the classic hypoglossus nerve as a new motor source because of its lower associated morbidity rate and the relative ease with which the patient can activate it. The aim of this work was to evaluate the effectiveness of masseteric-facial nerve neurorrhaphy for early facial reanimation. METHODS: Thirty-four consecutive patients (21 females, 13 males) with early unilateral facial paralysis underwent masseteric-facial nerve neurorrhaphy in which an interpositional nerve graft of the great auricular or sural nerve was placed. The time between the onset of paralysis and surgery ranged from 2 to 18 months (mean 13.3 months). Electromyography revealed mimetic muscle fibrillations in all the patients. Before surgery, all patients had House-Brackmann Grade VI facial nerve dysfunction. Twelve months after the onset of postoperative facial nerve reactivation, each patient underwent a clinical examination using the modified House-Brackmann grading scale as a guide. RESULTS: Overall, 91.2% of the patients experienced facial nerve function reactivation. Facial recovery began within 2-12 months (mean 6.3 months) with the restoration of facial symmetry at rest. According to the modified House-Brackmann grading scale, 5.9% of the patients had Grade I function, 61.8% Grade II, 20.6% Grade III, 2.9% Grade V, and 8.8% Grade VI. The morbidity rate was low; none of the patients could feel the loss of masseteric nerve function. There were only a few complications, including 1 case of postoperative bleeding (2.9%) and 2 local infections (5.9%), and a few patients complained about partial loss of sensitivity of the earlobe or a small area of the ankle and foot, depending on whether great auricular or sural nerves were harvested. CONCLUSIONS: The surgical technique described here seems to be efficient for the early treatment of facial paralysis and results in very little morbidity

Prevention of bisphosphonate-related mandibular fractures = Prevenzione delle fratture mandibolari conseguenti alla necrosi ossea da difosfonati

La frattura della mandibola rappresenta solitamente l\u2019evento finale nei pazienti che presentano una progressione della necrosi ossea derivante dall\u2019impiego dei difosfonati. Si tratta di una grave complicanza molto dolorosa che impedisce ai pazienti di alimentarsi correttamente, essendo pertanto un fattore che peggiora notevolmente la loro qualit\ue0 di vita. L\u2019obiettivo del trattamento dei pazienti che presentano la necrosi ossea legata ai difosfonati (BRONJ) dovrebbe essere rallentare la progressione della malattia. Presentiamo una soluzione tecnica per il trattamento dei pazienti che presentano necrosi mandibolare in stadio 3 ad alto rischio di sviluppare una frattura, avendo un\u2019altezza mandibolare residua di osso sano inferiore a 6 mm. Il trattamento consiste nel posizionamento di una placca ricostruttiva mandibolare per via extra-orale in un piano superficiale al muscolo platisma per tenere i mezzi di sintesi separati dal sito infettivo e non farli contaminare con conseguente necessit\ue0 di doverli rimuovere, seguito dal courettage per via endorale della necrosi mandibolare. Il rispetto della vascolarizzazione mandibolare e l\u2019assenza di contatto diretto tra il sito di osteonecrosi e la placca ricostruttiva rappresentano alcuni dei vantaggi di questa metodica. La placca ricostruttiva rinforza la mandibola e consente di aggredire energicamente l\u2019area di necrosi mandibolare, senza esporre il paziente a rischio di frattura iatrogena. Questo garantisce al paziente un rallentamento della progressione della malattia e impedisce la frattura patologica della mandibola, inevitabile epilogo delle necrosi ossee mandibolari.Mandibular fracture is usually the clinical end of bisphosphonate-related osteonecrosis of the jaw. This is a painful complication and patients cannot feed as usual, with a worsening of their quality of life. The goal of treatment in bisphosphonate related osteonecrosis of jaw (BRONJ) patients is to slow progression of bone necrosis. We present a novel technique for treatment of severe mandibular BRONJ in stage 3 patients that present with a high risk to develop fracture, since they have a residual unaffected mandibular bone height less than 6 mm. We treated 10 patients in this clinical situation with an extra-oral application of a reconstructive plate superficial to the platysma, to keep the plate separated from the infected site to avoid contamination and consequent need of removal, followed by an intraoral approach for active curettage of mandibular necrosis. The preservation of blood supply to the mandible and avoidance of direct contact of the infected site with the reconstructive plate are some advantages of this technique. This plate allows enhancement of mandibular strength, allowing proper treatment of the BRONJ site on the oral side without fear of causing a mandibular fracture when the residual mandible is thin. This technical solution guarantees these patients an extended disease-free period since it is effective in preventing mandibular fractures in patients with low mandibular residual height left after the BRONJ onset

Three-dimensional superimposition for patients with facial palsy: an innovative method for assessing the success of facial reanimation procedures

Facial palsy is a severe condition that may be ameliorated by facial reanimation, but there is no consensus about how to judge its success. In this study we aimed to test a new method for assessing facial movements based on 3-dimensional analysis of the facial surfaces. Eleven patients aged between 42 and 77 years who had recently been affected by facial palsy (onset between 6 and 18 months) were treated by an operation based on triple innervation: the masseteric to temporofacial nerve branch, 30% of the hypoglossal fibres to the cervicofacial nerve branch, and the contralateral facial nerve through two cross-face sural nerve grafts. Each patient had five stereophotogrammetric scans: at rest, smiling on the healthy side (facial stimulus), biting (masseteric stimulus), moving the tongue (hypoglossal stimulus), and corner-of-the-mouth smile (Mona Lisa). Each scan was superimposed onto the facial model of the "rest" position, and the point-to-point root mean square (RMS) value was automatically calculated on both the paralysed and the healthy side, together with an index of asymmetry. One-way and two-way ANOVA tests, respectively, were applied to verify the significance of possible differences in the RMS and asymmetry index according to the type of stimulus (p = 0.0329) and side (p < 0.0001). RMS differed significantly according to side between the facial stimulus and the masseteric one on the paralysed side (p = 0.0316). Facial stimulus evoked the most asymmetrical movement, whereas the masseteric produced the most symmetrical expression. The method can be used for assessing facial movements after facial reanimation
