COVID-19 and ENT Surgery

In Otorhinolaryngology – Head and Neck Surgery, clinical examination and invasive procedures on the respiratory tract and on airway-connected cavities, such as paranasal sinuses and the middle ear, expose people to direct transmission of SARS-CoV-2 by inhalation or ocular projection of contaminated droplets, and to indirect transmission by contact with contaminated hands, objects or surfaces. Estimating an R₀ of COVID-19 at around 3 justified postponing non-urgent face-to-face consultations and expanding the use of teleconsultation in order to limit the risks of SARS-CoV-2 infection of patients or health workers and comply with the lockdown. The health authority recommends cancellation of all medical or surgical activities, which are not urgent as long as this does not involve a loss of chance for the patient. The purpose of this cancellation is to significantly increase critical care capacity, prioritise the reception of patients with COVID-19, prioritise the allocation of staff and provision of the equipment necessary for their medical or surgical management, and contribute to the smooth running of downstream critical care within their establishment. Another goal is to reduce the risks of patient contamination within healthcare facilities. This document provides guidance on how to proceed with and adapt ENT surgery in the current pandemic context, as well as on the management of postponed operations. This best practice advice must of course be adapted in each region according to the development of the epidemic and pre-existing arrangements. Their local application can only be decided within the framework of collaboration between the ENT teams, the operational hygiene units and all the other specialties concerned.

Use of P-values and the terms "significant", "non-significant" and "suggestive" in Abstracts in the European Annals of Otorhinolaryngology, Head & Neck Diseases

OBJECTIVES

To evaluate the use of P-values and the terms "significant", "non-significant" and "suggestive" in Abstracts in the European Annals of Otorhinolaryngology, Head & Neck Diseases.

MATERIALS AND METHODS

Consecutive articles accepted for publication during the period January 2016 - February 2019 were systematically reviewed. Main goal: descriptive analysis of the citation of P-values and use of the terms "significant", "non-significant" and "suggestive" in Abstracts. Secondary goal: analytic study of: (i) correlations between citation of a P-value and the main characteristics of authors and topics; and (ii) misuse of the terms "significant", "non-significant" and "suggestive" with respect to cited P-values, and correlations with author and topic characteristics.

RESULTS

In all, 91 articles were included. P-values and the terms "significant", "non-significant" and "suggestive" were cited in 35.1%, 41.7%, 10.9% and 0% of Abstracts, respectively. Citing a P-value did not significantly correlate with author or topic characteristics. There were discrepancies between the terms "non-significant", "significant" and "suggestive" and P-values given in the body of the article in 57.1% of Abstracts, with 30.7% overestimation and 25.2% underestimation of results, without significant correlation with author or topic characteristics.

CONCLUSION

Authors, editors and reviewers must pay particular attention to the spin resulting from inappropriate use of the terms "significant", "non-significant" and "suggestive" in Abstracts of articles submitted to the European Annals of Otorhinolaryngology, Head & Neck Diseases, to improve the rigor, quality and value of the scientific message delivered to the reader.

[The tumors of the ear]

Any cutaneous lesion of the outer ear must be managed jointly by a dermatologist and an ENT, regardless of the age of the patient. The presence of a malignant cutaneous carcinoma (Squamous cell carcinoma or melanoma) of the pavilion requires a minimum extension assessment by a cervical ultrasound, CT-scan and MRI will be prescribed according to the degree of infiltration and the presence of clinics signs (lymphadenopathy, facial paralysis, cognitive impairment). A polyp of the external auditory meatus must be systematically biopsied in consultation and, if necessary, in the operating room with fresh anatomopathological analysis. Any "otitis externa", which does not progress favorably under local treatment, must lead to eliminate a tumoral pathology of the external acoustic meatus or of the middle ear. Any suspicion of cholesteatoma should lead to an ENT consultation to confirm the diagnosis and consider its treatment to limit the auditory dysfunction. Any unilateral neurosensorial hearing loss or unilateral vestibular involvement with normal otoscopy should lead to eliminate a inner ear tumor by an MRI of the inner ear and the ponto-cerebellar angle in millimeter sections.

Assessment and management of cervico-mediastinal goiter

Cervico-mediastinal goiter is a particular entity from the point of view of thyroid surgery. Its volume, hardness and intrathoracic extension require the surgeon to adapt technique and perform a painstaking preoperative work-up, so as to draw up fully-fledged plan. CT is now indispensable, to anticipate risks and determine whether sternotomy is needed. Surgery seems to induce more postoperative complications than in conventional surgery, although they can be reduced by retrograde dissection of the inferior laryngeal nerve and downward dissection of the posterior side of the lobe to optimize control of adjacent structures. This surgery requires optimal teamwork between all of the specialties involved in patient management: medical, radiological, anesthesiological and surgical.

Interest of video-assisted minimally invasive surgery in primary hyperparathyroidism

INTRODUCTION

Surgery is the only radical and definitive treatment for primary hyperparathyroidism. Exploration of the four parathyroid sites is giving way to minimally invasive techniques. The present study sought to compare two minimally invasive parathyroidectomy techniques, by classical cervicotomy (MIP-C) and by video-assistance (MIP-VA), in terms of success rate, complications rate, operating time, and patient and community physician satisfaction.

MATERIALS AND METHOD

A non-randomized retrospective comparative study included 112 patients presenting with primary hyperparathyroidism with identified parathyroid adenoma, operated on between January 2005 and October 2010. The two groups were constituted according to the surgeons' habitual practice: 54 cases of MIP-VA and 58 of MIP-C.

RESULTS

Results for MIP-VA and MIP-C were respectively: success, 96.3% vs. 100% (P=0.09); mean scar size, 1.47 vs. 3.43cm (P<0.01); hypocalcemia, 2 vs. 3 cases (P=0.1); theater time, 94.25 vs. 76min (P=0.02); and postoperative stay, 1.08 vs. 1.37 days (P=0.07). Patient satisfaction was comparable between groups, while 93.3% of community physicians found MIP-VA preferable to MIP-C, although only 39.3% had known the MIP-VA technique.

CONCLUSION

With efficacy, morbidity and patient satisfaction comparable to classical surgery, MIP-VA significantly reduced cervicotomy size and hospital stay. Community physicians considered it to be preferable to MIP-C.

Traumatic intra-sphenoidal pseudoaneurysm lodged inside the fractured sphenoidal sinus

We describe a case of traumatic intra-sphenoidal right internal carotid artery pseudoaneurysm lodged inside the fractured sphenoidal sinus that developed in a patient with a previous history of frontal and skull base fractures involving the sphenoid sinus and walls of the carotid canal, but with normal intracranial findings at early CT angiography. The patient presented two episodes of massive life-threatening delayed epistaxis before successful endovascular treatment combining the use of coils and an uncovered stent was instituted. This case report highlights that patients with head trauma who present sphenoid sinus fractures with or without massive epistaxis should be evaluated for the development of traumatic internal carotid artery pseudoaneurysm as soon as possible. If the first angiographic evaluation reveals normal findings, repeated epistaxis should prompt a second angiographic evaluation because psudoaneurysm takes time to develop. Early treatment with uncovered stent of the aneurysm can be a life-saving therapeutic approach.

Analysis of case reports submitted to the European Annals of Otorhinolaryngology Head & Neck Diseases

OBJECTIVES

To assess flaws, rejection rate and reasons for rejection of case reports submitted for publication in the European Annals of Otorhinolaryngology Head & Neck Diseases.

MATERIALS AND METHODS

A prospective analysis of flaws noted in reviewing 118 case reports from 29 countries consecutively submitted to the European Annals of Otorhinolaryngology Head & Neck Diseases during the period Sept. 1, 2014 to Sept. 30, 2015.

RESULTS

The most frequent flaws, noted in 74.5% of cases, were: lack of originality (more than 15 such cases previously reported in the medical literature) and lack of new data contributing to the medical literature. Overall, 5% of the cases were accepted for publication, 7% were not resubmitted by the authors, and 88% were rejected. On univariate analysis, none of the variables under analysis correlated with acceptance or rejection of the submitted case. Editorial decision time varied from 1 to 7months (median, 1 month). In 16.3% of the 104 cases of rejection (17/104), the editors suggested resubmission in the section "Letter to the Editor" or "What is your diagnosis?"; 15 of the 17 reports were resubmitted, and 10 (66.6%) were ultimately accepted for publication.

CONCLUSION

The editorial committee of the European Annals of Otorhinolaryngology Head & Neck Diseases hope that the present data and review of the literature will provide authors with a framework to avoid major errors leading to rejection and will speed publication of the case reports they submit to our columns in the near future.

Tracheal rhinoscleroma

INTRODUCTION

Tracheal rhinoscleroma is an infectious granulomatosis of the tracheobronchial tract caused by a Gram-negative bacillus. Exclusively tracheal involvement has been rarely reported in the literature. The purpose of this study was to report a case of subglottic stenosis secondary to rhinoscleroma.

SUMMARY

A 46-year-old North African woman with no medical or surgical history presented with inspiratory dyspnoea that had been present for several years. Endoscopic examination under general anaesthesia revealed tracheal stenosis. Histological examination of mucosal biopsies demonstrated Mikulicz cells and culture of bacteriological samples taken during a second biopsy confirmed the diagnosis of rhinoscleroma. CO2 laser subglottic obstruction relief was performed and treatment with ofloxacin was initiated. No recurrence of tracheal stenosis was observed with a follow-up of 6 months.

DISCUSSION

The diagnosis of rhinoscleroma is based on histological and bacteriological examination. Cultures are positive in 60% of cases, but negative cultures do not exclude the diagnosis of rhinoscleroma. Specific treatment consists of long-term antibiotic therapy, while surgery may be indicated for symptomatic treatment.

Characteristics and analysis of scientific articles submitted to the European Annals of Otorhinolaryngology, Head and Neck Diseases

OBJECTIVES

To evaluate characteristics, suggested modifications and reasons for rejection in scientific articles submitted for publication in the European Annals of Otorhinolaryngology, Head and Neck Diseases.

MATERIALS AND METHODS

A prospective study analyzed the flaws noted by reviewers in 52 scientific articles submitted to the European Annals of Otorhinolaryngology, Head and Neck Diseases between August 31, 2014 and February 28, 2015.

RESULTS

Fifteen flaws concerning content and 7 concerning form were identified. In more than 25% of submissions, major flaws were noted: purely descriptive paper; lack of contribution to existing state of knowledge; failure to define a clear study objective and/or analyze the impact of major variables; poorly structured Materials and methods section, lacking description of study population, objective and/or variables; lack of or inappropriate statistical analysis; Introduction verbose and/or misrepresenting the literature; excessively heterogeneous and/or poorly described study population; imprecise discussion, straying from the point, overstating the significance of results and/or introducing new results not mentioned in the Results section; description of the study population placed in the Results section instead of under Materials and methods; serious mistakes of syntax, spelling and/or tense; and failure to follow the Instructions to Authors. After review, 21.1% of articles were published, 65.3% rejected and 13.4% non-resubmitted within 3 months of review. On univariate analysis, the only variable increasing the percentage of articles accepted was the topic not being devoted to head and neck surgery (P=0.03).

CONCLUSION

These results document the excessive flaw rate still to be found in manuscripts and demonstrate the continuing need for authors to master and implement the rules of scientific medical writing.

French Society of ENT (SFORL) guidelines for care pathway organization in head and neck oncology (short version). Early management of head and neck cancer

Early management in oncology is based on coordination and high-quality exchange between the various health-care partners. The present guidelines are based on a literature search with levels of evidence. Treatment waiting time can be optimized by performing assessment as early as possible (Expert opinion), to limit the interval (ideally, less than 4 weeks) between first consultation and data collection. In the first specialist consultation, diagnostic work-up should be scheduled and the data required for management should be determined (Grade B). Work-up may be conducted on a day-care basis or with conventional admission (Expert opinion). The patient's medico-social context should be taken into account from the outset, with social work involvement whenever necessary (Expert opinion). Pain and nutritional management should be planned for (Grade A) and realistic therapeutic education be provided (Expert opinion). Community-hospital teamwork for supportive care should be optimized (Expert opinion). Management should be early and multidisciplinary, to shorten delay between diagnosis and treatment initiation.

Guidelines (short version) of the French Otorhinolaryngology - Head and Neck Surgery Society (SFORL) on patient pathway organization in ENT: The therapeutic decision-making process

OBJECTIVES

The authors present the guidelines of the French Otorhinolaryngology - Head and Neck Surgery Society (SFORL) for patient pathway organization in head and neck cancer, and in particular for multidisciplinary team meetings. The present article concerns the therapeutic decision-making process.

METHODS

A multidisciplinary work group was entrusted with a review of the scientific literature on the above topic. Guidelines were drawn up, based on the articles retrieved and the group members' individual experience. They were then read over by an editorial group independent of the work group. The final version was established in a coordination meeting. The guidelines were graded as A, B, C or expert opinion, by decreasing level of evidence.

RESULTS

It is recommended that: an organ specialist should contribute to all multidisciplinary meetings on head and neck cancer; all members of the multidisciplinary meeting should have specific knowledge in head and neck cancer; any referring physician who does not follow the multidisciplinary meeting's advice should justify that decision; there should be sufficient time to prepare, discuss and sum up the cases dealt with in the multidisciplinary team meeting.

Nodular recurrence and hypothyroidism following partial thyroidectomy for benign nodular thyroid disease in children and adolescents

OBJECTIVES

Diagnostic and therapeutic processing of a thyroid nodule in children and adolescents may require lobectomy-isthmusectomy (LI) or nodule-resection (NR). Very few data in the literature report the long-term evolution of the remaining thyroid lobe in a defined pediatric population. In this study, we aimed to answer the following questions: Does a nodule recurrence occur in the remainder lobe? Is a post-operative thyroxine treatment necessary?

MATERIAL AND METHODS

This retrospective study describes 28 patients under 18 who underwent LI (22 cases) or NR (6 cases) from January 2004 to March 2012. Ten of them were lost to follow up, 18 could be assessed (4 NR (22%) and 14 LI (78%) - mean follow-up 45±31 months). All patients benefited of post-operative thyroid ultrasonography, and regular endocrinologic follow-up. The following data were analysed: emergence of new thyroid nodules, evolution of pre-existing nodules, occurrence of post-operative hypothyroidism and requirement for completion thyroidectomy.

RESULTS

The mean age at the time of surgery was 14.3±1.9 years. Two patients (11%) had pre-existing nodules in the remaining thyroid gland, none of which showed an increase in size after surgery. De novo nodules developed in five patients (27.8%). Three patients who underwent LI (21.4%) needed thyroxine treatment for post-operative hypothyroidism. One patient (5.5%) needed completion thyroidectomy.

CONCLUSIONS

In this children and adolescents population, after performing LI or NR, remaining thyroid tissue stays free of nodules in 72.2% of the cases. A post-operative thyroxin treatment is necessary in 21.4% of cases after LI.

[Radiation therapy for pleomorphic adenoma of the parotid]

Parotid pleomorphic adenoma is the most frequent tumor of salivary glands. The prognosis depends on the recurrences because they could lead to iatrogenic events (facial paralysis). Moreover the risk of malignant transformation increases with the number of local relapses. This article aims at reviewing histological and radiological criteria and the surgical techniques. To improve local control, adjuvant irradiation (in first intention or after recurrence) may be useful but is still controversial for benign tumors in young patients with a risk of radio-induced cancer. We listed studies in which adjuvant radiotherapy was used so as to define its place in the treatment strategy. Prognostic factors were found by some authors. Other studies have to be done before strong evidence-based recommendations are issued.

Treatment of cervical paragangliomas

OBJECTIVE

Review of the treatment of cervical paraganglioma.

MATERIAL AND METHODS

Review of the literature based on a Medline database.

RESULTS

The treatment of choice consists of a multidisciplinary approach based on a detailed clinical, laboratory and radiological work-up. Vascular reconstruction may be necessary when the tumour invades the artery wall. The main complication of surgery is damage to cranial nerves involved in speech and/or swallowing. Treatment of bilateral tumours must be conducted in two stages. The first side to be operated depends on the sites and size of the tumours, as the primary objective is to avoid bilateral vagus nerve palsy. Radiotherapy has been used to treat paragangliomas for several years and achieves tumour stabilization in the majority of cases. Potential indications reported in the literature are: inoperable tumours, recurrence after surgery, some bilateral tumours and malignant tumours.

CONCLUSION

Surgery is the standard treatment for cervical paraganglioma. Radiotherapy can be proposed when surgery is contraindicated.

Cervical lymphadenopathies signaling thyroid microcarcinoma. Case study and review of the literature

BACKGROUND

Some lateral cervical lymphadenopathies may lead to the discovery of papillary microcarcinomas (PMC) of the thyroid that are not radiologically apparent. This relatively rare clinical situation raises questions about the diagnostic approach to chronic cervical lymphadenopathy and the impact of lymph node metastasis on PMC prognosis. PURPOSE OF THE ARTICLE: To study the epidemiologic, clinical, and prognostic criteria of cases of lymphadenopathy that signaled PMC.

PATIENTS AND METHODS

A retrospective study of 167 consecutive cases of PMC compared with 13 cases where a cervical mass signaled other forms of PMC.

RESULTS

The mean age was 48.5 years, the ratio of men to women was 5:8, and the mean PMC size was 5.5mm. These data did not differently significantly from those of the other PMC cases. The preoperative imaging found fluid content in six cases, with microcalcifications in three cases. All cases were treated by modified radical neck dissection on the side with the lymphadenopathy and total thyroidectomy with central neck dissection. The lymphadenopathy included a ruptured capsule in five cases and was accompanied by central lymph node metastases in three cases. Thyroid capsule involvement was significantly more common in cases of PMC discovered due to lymphadenopathy than in other cases of PMC (69% versus 9.7%, respectively; p<0.001). The mean follow-up was 7.3 years. There were no deaths due to PMC signaled by lymphadenopathy. Two cases of lymph node recurrence after 8 and 10 years were controlled by another surgery and radioactive iodine treatment.

CONCLUSION

Any chronic cervical mass should suggest the possibility of thyroid origin, especially in cases with cystic content or microcalcifications in subjects with no particular risk factors. An ultrasound of the thyroid should be done, as well as a fine needle aspiration biopsy of the lymphadenopathy with a thyroglobulin assay. Treatment is the same as for any thyroid carcinoma, and results in a good oncological outcome, despite the possibility of lymph node recurrences.

[Study of the platysma coli muscle vascularisation by the facial artery. Implication during the elevation of the musculo-cutaneous platysma coli muscle flap]

AIM OF THE STUDY

The purpose of this study was to assess the vascularity of the platysma muscle by the branches of the facial artery, in order to determine the best means of harvesting a musculo-cutaneous flap while ensuring maximum vascular security.

PATIENTS AND METHODS

Ten platysma muscles were dissected on 4 fresh specimens and one formaldehyde-preserved specimen. The dissection was performed after injection of the facial artery in 6 cases, while 4 muscles were dissected without any previous injection.

RESULTS

The vascular supply of the platysma muscle comes essentially from the branches of the submental artery and from branches descending straight from the facial artery. Other collateral branches contribute to this vascularization, but their importance is minor. All these arteries reach the muscle, entering its visceral aspect, then proceed to the sternal notch in a radial axis.

CONCLUSION

The size of the flap has to be defined within a quadrilateral figure with its base formed by the mandibular edge and its apex by the inferior limit of the flap. It is essential to preserve the maximum possible muscular thickness, especially on the medial side of the flap. If the facial artery needs to be ligated, this has to be done as it enters the submandibular space in order to protect most of the collateral branches destined to the muscle. The vascularization is then taken back by the homo- and contro-lateral facial vascularisation in an inverted flow in the remaining segment of the facial artery.

Surgical management of carotid body tumors

BACKGROUND

Carotid body tumors (CBT) should be considered when evaluating every lateral neck mass.

METHODS

A retrospective study was conducted of 52 patients with 57 CBT. The surgical approach and complications were reviewed. All patients were operated on without preoperative embolization.

RESULTS

Multifocal paraganglioma (PG) were detected in six cases. A succinate dehydrogenase subunit D (SDHD) mutation was discovered in four patients. Vascular peroperative complication occurred in one case. Vascular reconstruction was decided peroperatively in five cases (8.8%). Vascular reconstruction was 0% for Shamblin 1 or 2 tumors, but 28.5% for Shamblin 3. A postoperative nerve paresis was reported in 24 patients (42.1%) and vagal nerve paralysis persisted in four cases (7.01%). The rate of serious complications, e.g., permanent nerve palsy, preoperative and postoperative complications, was 14.03%; it was 2.3% for Shamblin 1 or 2 tumors and 35.7% for Shamblin 3. One patient had malignant PG with node metastasis and was not referred for radiotherapy. No recurrence or metastasis was reported after 6-year follow-up.

CONCLUSION

Early surgical treatment is recommended in almost all patients after preoperative evaluation and detection of multifocal tumors. Surgical excision of small tumors was safe and without complication, but resection of Shamblin 3 tumors can be challenging. Routine preoperative embolization of carotid body paragangliomas is not required.

[Voice handicap evaluation after supracricoid partial laryngectomy]

The importance of patient self-impressions has been emphasized in determining the success of cancer treatment. The supracricoid partial laryngectomy (SCPL) is recognized as a suitable procedure for the treatment of T1b and T2 glottic carcinoma. The aim of this surgical procedure is the preservation of a physiologic phonation with optimal oncologic control.

METHOD

Measurements included Voice handicap Index (VHI), Voice Related Quality of'Life (VRQL), subjective (GRBAS) and objective analysis.

OBJECTIVES

evaluate voice problems after SCPL, provide correlations between patients' daily activities, VHI, and subjective evaluation of the dysphonia.

PATIENTS

53 patients were assessed more than 1 year after SCPL. 26 patients, less than 60 years of age and professionally active were included. The mean age was 48 years (43 to 59 years). Eleven patients had professional activities in the communications industry requiring a compulsory daily use of their voices.

RESULTS

57.6% of the active patients underwent a cessation or an adaptation of their professional activities. The mean VHI was 52.22. It was respectively 36.3, 50.03 and 52.42 according to the grade 1, 2, 3 of dysphonia. Correlations between VHI and the time laps since intervention (p: 0.047). discontinuation of professional activities (p: 0.037), and grade of dysphonia (p: 0.049) were found.

CONCLUSION

VHI allows an evaluation of the voice problems after SCPL. A significant impact on voice is reported after SCPL and may influence the patient's life, with potential disturbance of their professional activities. Potential post surgical voice impact must be considered when the therapeutic options are discussed.

[Nasal involvement in Crohn's disease: report of a case and diagnostic difficulties of systemic diseases affecting the nose]

The authors describe the case of a 32 years old man with Crohn's disease who has developped sinonasal and tracheal localizations. The review of the literature, quite poor, allows to find some cases of nasal involvement in Crohn's disease and few associations between this illness and others systemic diseases as Wegener's disease or relapsing polychondritis. Among these diseases, we can find atypical conditions mixing different features of the most classical systemic diseases, which are called "overlap syndromes". The case we report illustrate these questions relative to the diagnosis. To conclude, it may be important to point at the difficulties of the anatomopathological diagnosis and the interest of the iterative biopsies. Regular follow-up can help us to identify systemic disease with the research of new extra-sinonasal symptoms.

Endoscopic surgical treatment of sinonasal polyposis-medium term outcomes (mean follow-up of 5 years)

BACKGROUND

Between 30 and 50% of patients with sinonasal polyposis (SNP) will require surgical treatment.

OBJECTIVE

To determine the medium term risks and benefits of endonasal ethmoidectomy in SNP.

METHOD

132 cases of SNP have been retrospectively studied before and after endoscopic nasal surgery with a mean follow-up of 5 years. Functional symptoms and appearances on endoscopic examination were recorded on graded scales. Non-parametric statistical analyses for matched series were used in the assessment of data.

RESULTS

Post-operative normalisation of nasal function was obtained in 62% of cases. Each of the four main nasal symptoms (nasal obstruction, rhinorrhoea, facial pain and anosmia) was improved (p = 0.001). Patients with associated asthma or ASA triad had higher scores for nasal obstruction and rhinorrhoea (Fisher's exact test; p < 0.02). The pre-operative clinical stage of SNP correlated neither with recurrence nor with functional outcomes (Fisher's exact test; p > 0.05). The requirement for steroid treatment of concurrent asthma was also reduced post-operatively (p = 0.001). The association with asthma and its level of treatment was not related to the frequency of recurrence of SNP (Chi2; p > 0.6).

CONCLUSIONS

Functional outcomes for patients with SNP and asthma were significantly improved by endoscopic surgical treatment, even if the appearance of the nasal mucosa did not always return to normal.

[Combined approach (endoscopic and external) for the treatment of sinusal mucoceles]

AIM OF THE STUDY

Determination of the best surgical approach in the treatment of mucocoeles of the sinuses according to their localization.

PATIENTS AND METHODS

A retrospective study has been carried out including forty three cases of sinus mucocoeles, surgically treated from 1990 to 1997. These were in descending order, frontal (n = 19), maxillary (n = 10), ethmoïdo-frontal (n = 9), sphenoidal (n = 3) and ethmoidal (n = 2). Surgical treatment was achieved with an exclusive endoscopic approach in 28 cases whereas 15 of them underwent endoscopic surgery associated with an external approach (also called combined technique). Short term complications and recurrence were recorded after a minimum of 6 years follow-up, according to the type of surgery performed and the topography of the mucocoele.

RESULTS

Recurrence of mucocoeles is prevented in 95.8% of cases by an exclusive endoscopic treatment in ethmoïdo-frontal, maxillary, sphenoidal and ethmoidal sites. On the other hand, the recurrence rate in mucocoeles involving the frontal sinuses without ethmoidal involvement, was significantly higher when the mucocoele was operated on by an exclusively endoscopic method (25%, p < 0.001) rather than by a combined technique (0%).

DISCUSSION AND CONCLUSION

Ethmoido-frontal, maxillary, sphenoidal and ethmoidal mucocoeles are excellent indications for an exclusively endoscopic endonasal surgery. An external approach, combined with endoscopic surgery, is suitable in frontal mucocoeles, especially in distal sites and in case of recurrence.

[Recurrent benign tumors of parotid gland: the role of the surgery]

Parotid gland tumor recurrences can prove problematic both in terms of facial nerve trauma during surgery and for the possible transformation into malignancy. Between 1981 and 2001 a total of 40 patients (23 women, 17 men; average age 48; age range 20-79 years) underwent surgery for recurrent parotid gland tumors. The average time between the first and the second surgical procedures was approximately 10 years. Five subjects underwent surgery several times for the same pathology. The Authors feel that MRI imaging is an essential tool for the evaluation of infiltrations into the soft tissues. The following surgical procedures were performed: enucleation in 2 cases; exofacial partial parotidectomy (PP) in 1; lower polar PP with functional neck dissection in 1; total parotidectomy (TP) with preservation of the facial nerve in 31 cases; TP with functional neck dissection in 2; TP with sectioning of the facial nerve in 2 and TP with transmandibular buccopharyngectomy and myocutaneous gran dorsal muscle flap in 1 case. Histology proved positive for the following: pleomorphous adenoma in 21 cases, adenocarcinoma in 11, aggressive fibromatosis in 2, cystadenolymphoma in 1, parotiditis in 1, lipoma in 1, cystic lymphoid hyperplasia in 1, histiofibrosarcoma in 1 and neurofibrosarcoma in 1. The surgical technique used was retrograde dissection of the facial nerve starting from one of the peripheral branches. Post-operatively, whenever a facial paralysis was encountered it proved difficult to recover. Paralysis of the nerve was permanent only in the 2 subjects where sectioning proved necessary because of infiltration by carcinoma. In 6 subjects recovery of the paralysis took one year, in 4 it took 6 months and in 2 other cases 3 months. In 22 cases there was only a slight paralysis of some branches which recovered during the post-operative period. We do not have definitive data on 4 subjects either because the period of time since surgery is still too short or because they did not come in for subsequent check-ups. The results of our study show that total parotidectomy should be the treatment of choice in case of benign parotid gland tumors and in particular for pleomorphic adenoma.

[Our experience with papillary microcarcinoma of the thyroid]

INTRODUCTION

Papillary microcarcinoma (PMC) of the thyroid gland is high incidence pathology. Most of cases are related to a good prognosis. Conversely, numerous cases are reported with an aggressive course. Prognosis factors are age, size of tumour, multifocality, capsular invasion and cervical lymphadenopathy.

MATERIAL AND METHOD

We have conduced a retrospective study about 4,208 consecutive thyroidectomies over a period of 16 years. 251 cases of papillary cancers were analysed including 64 PMC (25.5%).

RESULTS

90% of PMC were incidentally found and 59% were diagnosed during surgical procedure. Multifocality improved the sensibility of histological diagnosis (P = 0.04). In 78%, total thyroidectomy was performed associated with a selective neck dissection in 47%. In case of extemporaneous diagnosis all partial thyroidectomy was convert into total thyroidectomy. In case of delayed diagnosis and in the absence of unfavourable prognosis factor, no other surgical procedure was carried out. A 7 years mean follow-up revealed only one case of recurrence successfully treated with Iodine 131 ablation. There was no case of death due to PMC.

CONCLUSION

This study confirms the good prognosis of PMC treated according to usual criterions.

Nocardiosis revealed by thyroid abscess in a liver--kidney transplant recipient

Nocardiosis is a life-threatening infection, particularly among immunocompromised patients, which usually affects lungs, skin and central nervous system. We report a case of disseminated nocardiosis revealed by suppurative thyroiditis in a liver-kidney transplant recipient with poor nutritional status at the time of infection. Nocardia Asteroides was isolated from fine-needle aspiration material of the thyroid abscess. Clinical manifestations resolved after surgical drainage of the thyroid abscess, prolonged antibiotherapy and diminution of immunosuppressive regimen. Clinicians should be aware of this entity, as Nocardia Asteroides may need more than 5 days of culture to be isolated.

[Laryngomucoceles and subtotal C.H.E.P. reconstructive laryngectomy. Report of 6 cases]

We conducted a retrospective analysis of 131 patients who underwent subtotal CHEP laryngectomy for a tumor of the larynx between 1990 and 1999 in order to determine the incidence of laryngomucocele after surgery.

RESULTS

Five patients developed laryngomucocele late after surgery. A sixth patient underwent surgery in another unit. Laryngomucocele developed progressively or was disclosed by acute episodes of dyspnea, requiring tracheotomy again in two cases. One patient developed bilateral mucocele. Three patients had cervicotomy, and three others were treated by CO(2) laser endoscopic marsupialization.

DISCUSSION

We discuss the pathophysiology of late laryngomucocele after subtotal laryngectomy and various techniques that can be used to avoid this complication.

CONCLUSION

Although exceptional, laryngomucocele generally requires surgical removal by cervicotomy or CO(2) laser endoscopic marsupialization to prevent acute respiratory failure.

Intramuscular hemangioma of posterior neck muscles

Intramuscular hemangiomas of the head and neck are rare tumors, sparsely reported. They usually present themselves as a mass which enlarges suddenly. A case of intramuscular hemangioma involving the posterior neck muscles is presented. Computed tomography scanning, magnetic resonance imaging and angiography revealed the vascular nature of this lesion. Surgery consisted of a wide excision. The patient is free of disease after a 4-year follow-up.

[Substernal goiter. Report of 212 cases]

AIM OF THE STUDY

The aim of this retrospective study was to report the results of the surgical treatment in a series of 210 patients operated on for substernal goiters.

PATIENTS AND METHOD

From 1982 to 1996, 210 patients with substernal goiters, including 80% of women, were operated on via a cervical approach in 208 cases, via a sternotomy in two cases. Two patients with operative contra-indications were not operated on. Twenty-five were operated on for a substernal recurrence of a goiter. In 160 cases, extraction of the substernal portion was easy. In 48 cases, removal of the substernal portion was facilitated by the discovery of the recurrent nerve at its entering into the larynx and a downward dissection of the tracheal attachments of the lobe. The complete dissection of the cervical portion made easier the ascension of the substernal portion even in very large substernal components.

RESULTS

Three papillary carcinomas were diagnosed. A transient laryngeal nerve palsy occurred in 7.2% of the patients and a transient hypoparathyroidism in 13.4%, A definitive laryngeal nerve palsy occurred in 1.2% of the patients, and a persistent hypoparathyroidism in 2.1%. Of the 25 patients who underwent surgery for recurrence of a goiter, three (12%) developed a transient laryngeal nerve palsy, one (4%) a permanent nerve palsy, four (20%) a transient hypoparathyroidism and one (4%) a persistent hypocalcemia.

CONCLUSION

CT scan and MRI are the best explorations to evaluate intrathoracic extension of substernal goiters. Thyroidectomy was performed via a cervical incision in 208 patients and via a sternotomy in two patients only. The complete dissection of the cervical portion with discovery of the recurrent nerve at its entering into the larynx, facilitates the ascension of the substernal portion even in very large substernal goiters.

[Pleomorphic adenoma of the nasal septum: a case report]

We report on a case of pleomorphic adenoma involving the nasal septum, in a caucasian woman aged 23, who presented with nasal obstruction and epistaxis. A swelling of the anterior part of the nasal septum was observed and a biopsy demonstrated the existence of a pleomorphic adenoma. CT scan and MRI investigation showed the lesion to be limited, and removal was therefore possible using an endonasal approach. No recurrence has been found after 22 months.

[Imaging of the hypopharynx, oropharynx and parapharyngeal spaces]

Progress in upper aerodigestive imaging improved pathologic staging and therapeutic choices. Imaging, especially CT scan is now indispensable for staging the upper aerodigestive cancers. Some anatomic areas must be explored with special attention because of their importance for therapeutic decision.

Modified subtotal laryngectomy with cricohyoidoepiglottopexy--long term results in 81 patients

BACKGROUND

Standard treatment of early glottic carcinoma is radiotherapy, but involvement of the anterior commissure leads to a reduced cure rate. We investigated retrospectively whether our modified subtotal laryngectomy had improved results for early glottic carcinomas involving the anterior commissure, without causing excessive disability to laryngeal functions.

METHODS

Eighty-one patients with T1 or T2 glottic carcinoma involving the anterior commissure were reviewed. Follow-up was at least 3 years. Speech was assessed by subjective evaluation and a computer-assisted voice analysis device.

RESULTS

Three-year overall survival rate and 3- and 5-year actuarial survival rates were, respectively, 90.1%, 95%, and 90.8%, with no difference between the different T stages involved (p > 0.46). The local recurrence rate was 7.4%. Speech recovered in all patients and was evaluated as satisfactory in 86% of cases.

CONCLUSION

For early glottic carcinomas involving the anterior commissure, subtotal laryngectomies appear to be more effective than radiotherapy, and our modified technique simplifies the procedure.

[Repeat surgery for thyroid nodules (excluding cancer and hyperthyroidism)]

Second procedures for recurrent thyroid disease are known to carry a high risk of iatrogenic damage, particularly to the inferior laryngeal nerves and parathyroid glands. This risk has been clearly evaluated for the primary procedure, but is less clearly for second procedures. A series of 117 patients with solitary or multiple cold thyroid nodules were evaluated (excluding those patients re-operated for recurrent thyroid carcinoma or goitre associated with hyperthyroidism) to determine the operative risks. The level of transient and permanent recurrent laryngeal nerve palsy was 2.56% and 1.7% respectively. The level of transient and permanent hypocalcaemia was 12.9% and 4.62% respectively. The frequency of re-operation for recurrent disease involving the pyramidal lobe following total thyroidectomy (6 cases) highlights the importance of removing it during the primary procedure. The number of cases of cancer discovered at re-operation was 4.3% (5 cases out of 117).

Maxillary sinus mucocoeles--10 cases--8 treated endoscopically

Maxillary sinus mucocoeles are rare, but may cause significant problems outside the sinus including diplopia and cheek swelling. We present 9 patients suffering from maxillary sinus mucocoele, including one patient with bilateral involvement, representing 10 involved sinuses. Eight sinuses were treated endoscopically and followed-up for 3 to more than 6 years; one of these developed a recurrence. Two sinuses were treated using a classical external approach (Caldwell-Luc), one at the beginning of our series, and one as the endoscopic technique was difficult to perform due to loss of anatomical landmarks. One of these two sinuses developed a recurrence and was then successfully treated endoscopically. We discuss the aetiology, pathogenesis and appropriate treatment of this unusual condition. Endoscopic treatment appears to be effective and leads to minimal recurrence. The aim is to perform a wide removal of the medial wall of the maxillary sinus including most of the inferior turbinate, immediately posterior to the lachrymal duct leaving intact the sinus mucosa. In some cases, however, the endoscopic technique can be difficult to perform due to loss of essential anatomical landmarks and in these cases recourse to an external approach may be necessary.

[Pyolaryngocele: a rare cause of respiratory distress]

Pyolaryngocele is an unusual diagnosis, occurring as a complication of a laryngocele, witch may be discovered because of an episode of acute respiratory distress needing urgent medical care. This is a case report with confirmation of the diagnosis by CT scan, which needed surgical treatment.

[Chemical labyrinthectomy: results and applications]

GOAL OF THE STUDY

Unilateral Menière's disease can be treated by chemical labyrinthectomy. The goal of this work was to report our clinical experience with chemical labyrinthectomy, and to discuss the respective value of labyrinthectomy and of vestibular neurotomy for treating unilateral Menière's disease.

METHODS

Twelve patients underwent chemical labyrinthectomy using middle ear gentamicin infusion. Before treatment, patients had a pure tone audiogram and a vestibular caloric testing. After treatment, patients had a clinical assessment at 1 and 6 months after treatment (pure-tone audiogram, vestibular caloric testing), and answered a questionnaire at 1 and 2 years following the treatment (number of vertigo attacks, ataxia, tinnitus, subjective assessment of the method by the patient).

RESULTS

At two years post-treatment, the vertigo cure rate was 91.6% (ABC using AAOO criteria), vestibular function was abolished in 70% of cases, ataxia was reported in 42% of patients, 16.6% of patients had hearing deterioration above 20 dB HL (C following AAOO criteria), tinnitus was decreased in 50% of cases. Of 12 patients, 8 were satisfied.

CONCLUSION

Chemical labyrinthectomy cures vertigo in Menière's disease, with similar cure rate than vestibular neurotomy. Minor complications can occur with chemical labyrinthectomy. This method should be used in more patients.
