Variability in facial-muscle innervation: A comparative study based on electrostimulation and anatomical dissection.

Facial-nerve palsy is the most common complication during facial surgery. However, there are few detailed reports on the distribution of the terminal branches of the facial nerve to the mimetic muscles. This also applies to the communicating branches. The aim of our study was to assess the variability of communicant and terminal branches of the facial nerve in humans. This prospective study involved anatomical dissections and intraoperative electric stimulation of facial nerves. We first performed 30 dissections to define the branching patterns of the extracranial facial nerve, with particular focus on the penetrating points into the mimetic muscles. We then studied and compared these preliminary data with 14 operative facial stimulations conducted during parotidectomies. Each trunk and branch received systematic electrostimulation. The electrostimulation and facial-and-neck movements were analyzed by two independent reviewers. The peripheral branching and intercommunication of the facial branches were highly variable. Combining electrostimulation and dissections, the frontalis muscle, the depressor labii inferioris and the platysma showed little nerve recuperation whereas the sphincter muscles (orbicularis ori and oculi) were anatomically protected. Facial-muscle innervation differed among individuals. We found complex variations in the facial branching mode. Our study highlights the branches and corresponding areas that could be considered anatomically risky. Clin. Anat. 32:169-175, 2019. © 2018 Wiley Periodicals, Inc.

Long-term carcinologic results of advanced esthesioneuroblastoma: a systematic review.

Surgical resection followed by radiotherapy can be considered like the optimal treatment modality for limited esthesioneuroblastoma. However, therapeutic management of locally advanced tumors remains a challenge. The aim of our study was to access and compare the oncologic results of the different treatment modalities in advanced esthesioneuroblastoma. We performed a systematic review using the Medline, and Cochrane database in accordance with PRISMA criteria and included all the cases of advanced esthesioneuroblastoma published between 2000 and 2013. We also retrospectively included 15 patients with an advanced esthesioneuroblastoma managed at our tertiary care medical center. Long-term survival rates defined as the time from diagnosis or randomization to the date of death or last follow-up were evaluated for each treatment with Kaplan-Meier survival curve analyses. 283 patients have been included. The mean follow-up was 78 months. Five-year highest survival rates were obtained in patients treated by surgery associated with radiotherapy. Ten-year highest survival rates were obtained in patients treated by the association of surgery, radiotherapy and chemotherapy (p = 0.0008). Within the surgical group, 5-year highest survival rates were obtained in patients treated by endoscopic resection (p = 0.003). Surgical resection combined with radiotherapy offers the gold standard of care. Adjuvant chemotherapy seems to improve the long-term survival in patients with locally advanced esthesioneuroblastoma. Endoscopic resection in advanced tumors should be discussed on a case-by-case basis.

Sialendoscopy learning curve: comparing our first and last 100 procedures.

OBJECTIVES: Sialendoscopy is a relatively new minimally invasive technique that permits direct salivary tree visualization and is important in obstructive sialadenitis management and treatment. The present study aimed to examine the sialendoscopy learning curve between March 2009 and March 2013. METHODOLOGY: We compared the first and last 100 sialendoscopies performed in our department with regard to anaesthesia type, operating time, success rate, technical difficulty, major complications, and clinical improvement. RESULTS: General anaesthesia rates were 63% and 38% (P = 0.0004) among the first and last 100 sialendoscopies, respectively. Among the first and last 100 procedures, respectively, average operating times were 39 and 25 minutes (P = 0.00055) for diagnostic sialendoscopies and 68 and 65 minutes (P = 0.35) for interventional sialendoscopies. Successful stone extraction rates were 65% and 90.2% (P = 0.0058) among the first and last 100 procedures, respectively, while the corresponding rates of successful stenosis dilation were 92.5% and 97.1% (P = 0.27). Technical difficulty was encountered in 25% and 17% (P = 0.164) of the first and last 100 sialendoscopies, respectively. Neither group experienced major complications. All patients tolerated the procedures well and had excellent outcomes. CONCLUSION: Progressive learning regarding sialendoscopy enabled more frequent operation under local anaesthesia, thus better meeting the requirements of a minimally invasive technique. We were able to decrease the operative time in diagnostic sialendoscopy. These two factors support the inclusion of diagnostic sialendoscopy into the diagnostic panel in obstructive glandular diseases.

A case of laryngeal sialolipoma: pathology in focus.

We are reporting a rare case of laryngeal sialolipoma in a 66-year-old male affected by Parkinson's disease. He was evaluated for dysarthria and swallowing disorders during which a swelling of the left ventricular fold, was always present and enlarged over a span of six months. Surgical removal of the left ventricular fold was performed. Microscopic examination, showed a circumscribed mass with organoid seromucous glands surrounded by numerous mature adipocytes, separated from the parenchyma and fatty tissue by dense fibrous tissue. This mass fulfilled the diagnostic criteria of sialolipoma. Sialolipomas can develop in a variety of sites in which there is both adipose and salivary gland tissue. To our knowledge, this is the first case of sialolipoma arising in the larynx.

[Transsexualism: from diagnosis to management]. / Transsexualisme: du diagnostic à la prise en charge thérapeutique.

The transsexualism or gender dysphoria is a pathology during which an individual does not recognize himself in his sexual identity and wishes to change it: in that it must be differentiated from the sexual ambiguities (hermaphrodism, pseudohermaphroditism) in which the sexual phenotype is not clearly established. In France the number of transsexuals is estimated at approximately 50,000 people. Since 2009 the transsexualism is not any more considered as a mental illness, it remains regarded as a long term illness. The objective of this article is to present the recent evolutions concerning the management of transsexual patients seeking feminization.

[Learning curve in sialendoscopy: Our first 101 procedures]. / Courbe d'apprentissage en sialendoscopie : nos 101 premières procédures.

OBJECTIVE: To present our learning curve in diagnostic and interventional sialendoscopy for obstructive salivary diseases. MATERIALS AND METHODS: Monocentric descriptive retrospective study from March 2009 to July 2011. Clinical and demographic data were collected. We are particularly interested in arising technical issues, the use of combined approach, operative time, functional improvement as well as parameter changes over time. RESULTS: 92 operations were performed to explore 101 glands (63 parotid glands against 38 submandibular). We found 39.6% of stones and as many stenosis. The rate of complete stone removal was 65% and dilation was effective in 75% of stenosis. The median of the visual analog scale for pain was 1/10 and functional improvement was effective in 77%. The removal of the gland did not exceed 3.3%. No major complication was noted. Since the initiation of this activity, the median operative time was steady while procedures were more complex, with increased interventional sialendoscopy procedure often requiring combined approach. In about 25% of cases, we have been faced with technical issues. These have evolved over time: initially failure to enter the papilla, difficulty of removing large stones today. CONCLUSION: The learning curve in sialendoscopy allows rapid empowerment and acquisition of expertise in security. Mastery of this technique allows for innovative approaches, complementary to conventional procedure, without compromising neither the operative time nor the functional benefit.

[How I do it: salivary duct preservation in the excision of small oral tumors]. / Transposition des canaux salivaires principaux dans la résection de tumeurs endobuccales superficielles.

Benign tumors, in-situ carcinomas and small carcinomas of the anterior floor mouth or of the internal surface of the cheek may require resection of salivary duct papilla i.e. papilla of submandibular duct or Stensen's duct. If a lymph node dissection is not required, excision of submandibular or parotid duct which papilla is interested in the resection can be avoided using a surgical technique not reported. The authors present two cases illustrating a simple surgical proceeding of salivary duct resection/transposition. The present method can be used to keep a functional principal salivary gland with an optimal oncologic result.

Narrow-Band Imaging in oncologic otorhinolaryngology: State of the art.

OBJECTIVES: To describe the diagnostic performance of Narrow Band Imaging (NBI) combined with White Light Imaging (WLI) in the diagnosis of mucosal lesions at each location of the upper aerodigestive tract, for detection of primary tumor in case of carcinoma of unknown primary, for determination of intraoperative resection margins, and to describe its main diagnostic pitfalls. MATERIAL AND METHODS: A PubMed search was carried out according to the PRISMA method. RESULTS: Four hundred and seventy-seven articles published between 2007 and 2020 were identified, 133 of which met the study inclusion criteria and were assessed. CONCLUSION: The current literature seems to support the use of NBI in diagnosis and/or follow-up of (pre-)malignant head & neck tumors, and in the determination of intraoperative resection margins.

Surgical management of maxillary sinonasal inverted papilloma.

OBJECTIVE: The extent of the surgery required when sinonasal inverted papilloma (IP) originates in the maxillary sinus is still the subject of debate. The principal aim of the study was to evaluate the efficacy of exclusive endoscopic removal or when combined with a limited vestibular anterior antrostomy of the maxillary IP. METHODS: A retrospective analysis was carried out of 64 patients with IP treated in our university tertiary referral center from 1993-2007. Endoscopic removal of the IP was done for all patients, either exclusively or combined with an open approach. All patients were followed up for more than 1 year and the local control rate has been compared between patients with maxillary IP and others, and with both approaches. RESULTS: The overall recurrence rate was 14% (9/64), for a mean follow up of 48 months (12-120 months). Twenty-three patients (23/64) had maxillary IP. Ten of them had endoscopic resection alone, 13 had a combined approach (1 with lateral rhinotomy). There were 4 recurrences (17%) three of which had had endoscopic surgery alone. We did not perform a medial maxillectomy in the first instance. There were no cases of epiphora or atrophic rhinitis. conclusion: We showed that the combined method (endoscopic assisted by a minimal vestibular approach) was an efficient and safe method to treat maxillary sinus IP. This approach could preserve the lacrimal duct and the inferior turbinate when these structures were not involved, even when there was a large maxillary sinus extension of the disease.

Transoral robotic surgery of the tongue base for obstructive sleep apnea: Preliminary results.

INTRODUCTION: Obstructive sleep apnea syndrome (OSAS) is a major public health issue. Robotic tongue-base reduction surgery is being developed, but needs assessment. The present study reports clinical and polygraphic results at 6 months' follow-up. METHOD: Single-center prospective study of 8 patients undergoing transoral robotic surgery (TORS) for severe OSAS. RESULTS: Mean age was 47 years. M/F sex ratio was 5:3. Initial body-mass index ranged from 18 to 35kg/m2. Mean Epworth score was 12. Mean preoperative apnea-hypopnea index (AHI) was 47 (range, 36-60). At 6 months, only 1 patient did not meet usual success criteria (AHI<20 with>50% decrease); 2 patients had residual AHI between 10 and 20; the other 5 had non-significant event rates. CONCLUSION: TORS tongue-base reduction showed promising results, which need confirmation on long-term multicenter studies.

Possible role of anti-inflammatory drugs in complications of pharyngitis. A retrospective analysis of 163 cases.

OBJECTIVES: Complications of pharyngitis (peritonsillar abscess, retropharyngeal abscess, and cervical cellulitis) are rare, but appear to be on the increase over recent years and many of these patients have been treated by anti-inflammatory drugs prior to admission. The purpose of this study was to review the current epidemiological data concerning these complications and investigate a possible correlation with anti-inflammatory drug use. MATERIAL AND METHODS: A single-centre retrospective review of epidemiological, clinical and microbiological data was performed on the medical charts of patients hospitalised for peritonsillar abscess, retropharyngeal abscess or cervical cellulitis between 2005 and 2010. RESULTS: Over a six-year period, 163 patients were hospitalised for complications of pharyngitis, with a sex-ratio of 1.82 (104/57). The number of cases of peritonsillar abscess (PTA) increased from 13 to 28 cases per year from 2005 to 2010 and the number of cases of retropharyngeal abscess increased from three to six cases per year over the same period. The number of cases of cellulitis remained stable with an average of 1.82 cases per year. Each year, significantly more patients with an abscess were admitted to our unit with a history of anti-inflammatory drug use (13.3 ± 4.6) than without anti-inflammatory drug use (7.8±4.3) (P<0.01). Micro-organisms were identified in 80% of cases, with mixed strains in 73% of cases, Streptococcus in 72% of samples and Streptococcus pyogenes in 19% of cases of PTA. A favourable outcome was observed in all patients in response to medical and surgical treatment. CONCLUSION: In line with the literature, we observed an increasing incidence of complications of pharyngitis. The present series comprised significantly more patients admitted for PTA with a history of anti-inflammatory drug use. A multicentre prospective controlled study in Nantes on a large cohort is currently underway and will probably confirm these preliminary results.
