Patient information ahead of thyroid surgery. Guidelines of the French Society of Oto-Rhino-Laryngology and Head and Neck Surgery (SFORL)

OBJECTIVE

The authors present the guidelines of the French Society of Oto-Rhino-Laryngology and Head and Neck Surgery (SFORL) on patient information ahead of thyroid surgery.

METHODS

A multidisciplinary medical team was tasked with a scientific literature review on this topic. The texts retrieved were analyzed by an independent committee. A joint meeting drew up the final guidelines. The strength of the recommendations (grade A, B or C) was based on levels of evidence.

RESULTS

It is recommended that the results of preoperative exploration and the indications for surgery should be explained to the patient. Patients should be informed as to the type of surgery, surgical objectives, risks and consequences. It is mandatory to obtain the patient's written consent before surgery.

CONCLUSION

Appropriate medical information is a critical step in patient management.

Descending mediastinitis with mediastinal abscess after supracricoid partial laryngectomy

We document a rare and not-yet-reported condition after supracricoid partial laryngectomy: the development of descending mediastinitis with mediastinal abscess. We present a case in which early diagnosis and team management allowed for a successful outcome. The pathophysiology of this severe complication, as well as its diagnosis, management, and prevention, is discussed, together with a review of the medical scientific literature.

PROKR2 and PROK2 mutations cause isolated congenital anosmia without gonadotropic deficiency

OBJECTIVE

Isolated congenital anosmia (ICA) is a rare phenotype defined as absent recall of any olfactory sensations since birth and the absence of any disease known to cause anosmia. Although most cases of ICA are sporadic, reports of familial cases suggest a genetic cause. ICA due to olfactory bulb agenesis and associated to hypogonadotropic hypogonadism defines Kallmann syndrome (KS), in which several gene defects have been described. In KS families, the phenotype may be restricted to ICA. We therefore hypothesized that mutations in KS genes cause ICA in patients, even in the absence of family history of reproduction disorders.

DESIGN AND METHODS

In 25 patients with ICA and olfactory bulb agenesis, a detailed phenotype analysis was conducted and the coding sequences of KAL1, FGFR1, FGF8, PROKR2, and PROK2 were sequenced.

RESULTS

Three PROKR2 mutations previously described in KS and one new PROK2 mutation were found. Investigation of the families showed incomplete penetrance of these mutations.

CONCLUSIONS

This study is the first to report genetic causes of ICA and indicates that KS genes must be screened in patients with ICA. It also confirms the considerable complexity of GNRH neuron development in humans.

Lack of Adverse Events after Medialization Laryngoplasty with the Montgomery Thyroplasty Implant in Patients with Unilateral Laryngeal Nerve Paralysis

Objectives:

We sought to document the incidence of and risk factors for adverse events after medialization laryngoplasty with Montgomery implant insertion in patients with unilateral laryngeal nerve paralysis.

Methods:

We studied a retrospective series of 191 patients consecutively managed at a university teaching hospital.

Results:

No adverse events were noted in 79.8% of the patients. Intraoperative, immediate, and late postoperative adverse events were noted in 8.3%, 8.9%, and 4.1% of the patients, respectively. The various adverse events noted were failure to insert the implant (3.6%), difficulties in stabilizing the implant (4.8%), misplacement of the implant (2.1%), dyspnea (2.7%), hematoma (4.8%), extrusion (1.6%), persistent morphological laryngeal alterations (1.6%), and keloid scars (1.1%). Tracheotomy, procedure-related death, and infection at the insertion site were not encountered. No significant statistical relationship was noted between the various adverse events encountered and the variables under analysis.

Conclusions:

Our data demonstrate that medialization laryngoplasty with Montgomery implant insertion in patients with unilateral laryngeal nerve paralysis from various causes is a relatively safe, reliable, and reproducible procedure with a short learning curve.

Trade-off between Survival and Laryngeal Preservation in Advanced Laryngeal Cancer: The Otorhinolaryngology Patient's Perspective

Objectives:

We performed a prospective study to evaluate, from the patient's perspective, the trade-off between speech and survival that individuals face when given a diagnosis of advanced-stage laryngeal cancer amenable to either total laryngectomy or a laryngeal preservation protocol using chemotherapy and radiotherapy.

Methods:

Volunteers (309) consecutively seen at the otorhinolaryngology clinic of a university teaching hospital in France completed an anonymous questionnaire designed to determine their position if they faced the diagnosis of an advanced-stage laryngeal cancer. Univariate analysis was performed for potential statistical relationships with various variables.

Results:

We found that 12.9% of patients were unable to determine their position regarding the two treatment options offered, and this group had a significant statistical relationship with four variables (age, education, professional status, and history of cancer among relatives). We found that 24.6% of patients made survival their main consideration and would not consider any trade-off. Among the 62.5% who considered the trade-off, the percentage of cure that patients were ready to lose in order to preserve their larynx varied from 5% to 100% (mean, 33%; SD, 23%). Aside from the undecided group, none of the variables analyzed was related either to the decision as to whether to consider a trade-off or to the percentage of cure that patients agreed to trade to preserve their larynx.

Conclusions:

In patients with advanced-stage laryngeal cancer, treatment should be initiated only after careful evaluation of the patient's attitude toward both laryngeal preservation and survival.

Inverted papilloma of the middle ear

INTRODUCTION

Inverted papilloma (IP) of the middle ear is a very rare lesion, as less than 20 cases have been reported in the literature.

CASE REPORT

The authors report the case of a 73-year-old male with IP of the middle and external ear that had already been operated many times. Treatment consisted of creating a large resection cavity. No recurrence was observed on clinical examination or MRI with a follow-up of 2 years.

DISCUSSION AND CONCLUSION

This case is analysed in the light of a review of published cases with a discussion of the pathophysiological and treatment problems raised by these lesions.

Functional organ preservation for laryngeal cancer: past, present and future

OBJECTIVE

Management of laryngeal cancer has focused on improving survival while preserving function. Over the past 20 years, the trends have shifted from surgery to chemoradiotherapy and presently we are facing various challenges. It is imperative to re-examine what has happened and what can be done.

METHODS

Review of the literature along with our experience in the management of functional organ preservation for laryngeal cancer.

RESULTS

There was an increasing use of chemoradiotherapy with a decreasing use of surgery. Inappropriate patient selection along with inability to properly apply salvage surgeries have been presumed to be responsible for survival deterioration in laryngeal cancer. Reports concerning late adverse events after chemoradiotherapy are also increasing. Reconfirmation of the multidisciplinary team approach is imperative. Transoral laser microsurgery can be used for early laryngeal cancer and, in some experienced institutes, for advanced-stage cancers. Supracricoid laryngectomy demonstrated satisfactory oncologic and functional outcomes, based on our experience.

CONCLUSIONS

Treatment selection for larynx preservation should not merely be decided by guidelines but considering each patient's individual condition. Head and neck surgeons are encouraged to take reasonable risks in performing salvage larynx preservation surgery when it is the only option to save a functioning larynx.

Sinus mucocele: natural history and long-term recurrence rate

OBJECTIVE

To define the natural history, clinical signs, treatment and the modalities of medium- and long-term follow-up of patients operated for sinus mucocele.

PATIENTS AND METHOD

Retrospective study of all patients operated for sinus mucocele between January 1993 and December 2009 (n=68). Demographic data, symptoms, medical imaging findings, surgical treatment and results were recorded.

RESULTS

The mean age of patients in this series was 53 years (range: 27-82 years, sex ratio: 3/2). The most common site was fronto-ethmoidal. Fifty-one patients (75%) had a history of sinus surgery, essentially for nasal polyposis. Only 15% of mucoceles occurred spontaneously. Presenting symptoms, in decreasing order of frequency, were facial pain or headache (38%), ocular or orbital complications (28%), while 20% of patients were asymptomatic. Surgery was performed by endonasal endoscopic sinus surgery (n=57, 84%) or via a combined, transfacial and endonasal approach, associated with navigation after January 2003. The mean follow-up was 7 years (range: 4 months-16 years). During this follow-up period, 23.5% of patients developed recurrence or a second mucocele after a mean interval of 4 years.

CONCLUSION

This study demonstrates the high recurrence rate of mucocele, particularly in multi-operated patients with chronic sinusitis. Long-term, regular, clinical and radiological follow-up is necessary to detect asymptomatic lesions prior to the onset of complications.

Complications of Thyroplasty Type I with Montgomery Implant

Objective: Document the incidence and risk factors for significant complications in patients with a unilateral laryngeal nerve paralysis managed with thyroplasty type I and Montgomery implant insertion.

Method: Inception cohort of 181 patients with 104 patients followed for a minimum of 12 months or until death. Data regarding significant complication were obtained at regular visits to our clinic. Univariate analysis was performed for potential statistical relation between the complications noted and various variables.

Results: The intraoperative and postoperative course was unremarkable in 85.6% and 92.3% of cases. No patient died from the procedure. Significant complications included Montgomery implant replacement by a Gore-tex implant (7), difficulty to stabilize the implant (8), misplacement of the implant (3), hematoma (8), severe dyspnea (5), and extrusion of the implant (5). A 5.5% revision rate was found (10/181). No significant statistical relation was noted between the complications noted and the variables under analysis.

Conclusion: The reported data suggest that the Montgomery implant insertion is a safe technique with a low incidence for complication. The lack of a statistically significant difference between senior and junior surgeons also suggests the absence of a learning curve in this procedure.

[Evolution of laryngectomy based on a comparison of two cohorts a century apart: an illustration of the progress, difficulties and conflicts encountered in medicine]

Based on a comparison of two cohorts of patients with laryngeal cancer managed by laryngectomy one century apart, and an analysis of original textbooks from the end of the nineteenth century, we examine the development of laryngectomy, the difficulties encountered in this first therapeutic approach to laryngeal carcinoma, and the conflicts it generated. The overall death rate changed little over the course of a century, although the 5-year actuarial survival estimate improved from 22.6% in 1888 to 75.1% in 1988 (p < .0001). The causes of death also changed (p < .0001), with fewer deaths related to post-operative complications and/or local failure (82.7% in 1888, 9% in 1988). The rate of suicide deaths fell from 1.8% to 0.04%. In contrast, the percentage of deaths due to metachronous second primary tumors and/or intercurrent disease increased from 9% in 1888 to 76.7% in 1998. Analysis of actuarial survival rates demonstrated that 77.4% of patients died before the 60th post-operative month in 1888, while this percentage was only reached 275 months post-operatively a century later. Our research also underscores the importance of patient information and medical ethics.

[Unilateral laryngeal paralysis in the adult patient]

Based on a review of the recent medical literature, the authors document the epidemiological evolution, pathophysisology diagnosis and recent advances in treatment for adult patients with unilateral laryngeal paralysis. Speech therapy, which used to be the only therapeutic option, is nowadays complemented by efficient surgical techniques, which have modified the management of many patients.

Writing an article for the European Annals of Otorhinolaryngology, Head and Neck Surgery: rights and responsibilities

Based on a review of the literature published on medical writing, the authors discuss the rules to respect in terms of both structure and substance to facilitate publication of studies in the European Annals of Otorhinolaryngology, Head and Neck Surgery. The main errors leading to an article's being rejected are detailed and analyzed.

Imported acute and isolated glottic paracoccidioidomycosis

The current report documents the rare clinical presentation of an imported acute and isolated glottic paracoccidioidomycosis. We discuss the diagnosis, pathogenesis, and treatment of this laryngeal disease, emphasizing the role of modern antifungal treatment, and review the relevant literature.

[Isolated unilateral laryngeal nerve paralysis in adults. An inception cohort of 591 patients managed in a French--university--teaching hospital]

We analyzed an inception cohort of 591 adults with isolated unilateral laryngeal paralysis managed at a French teaching hospital during the period 1990-2008. Symptoms, causes, treatment and outcome were compared between two periods (1990-2000 vs 2001-2008), using the Chi squared test and Mann Whitney U test. Dysphonia, swallowing impairment and respiratory impairment were present in respectively 98.3%, 34.8% and 4.1% of cases, The causes of paralysis were surgical and non surgical in respectively 65.1% and 21.1% of cases. Cancer (mainly lung cancer) was present in 59.6% of cases, and 22% of these patients were receiving palliative treatment. Thoraco-mediastinal surgery and thyroid-parathyroid surgery accounted for 79.4% of surgical causes. Malignancies accounted for 76.8% of non surgical causes. Within the idiopathic group (13.8% of the cohort), a tumor lying along the path of the paralyzed nerve was detected in 3.7% of cases. Larynx motion was recovered in 19.6% of cases; nerve transection, the etiology, and the time since symptom onset were predictive factors for motion recovery. Treatment consisted of laryngeal medialisation and isolated speech therapy in 40.1% and 59.9% of cases, respectively. The current success rate of laryngeal medialisation is 90.3%.

CONCLUSIONS

The three main causes of unilateral laryngeal nerve paralysis were tumors, surgery and cardiovascular disorders (surgical and non surgical). Laryngeal medialisation is now a major component of rehabilitation in our center.

Platin-based exclusive chemotherapy for selected patients with squamous cell carcinoma of the larynx and pharynx

BACKGROUND

The current study was conducted to determine the long-term outcomes of patients with squamous cell carcinoma of the larynx and pharynx who were treated with platin-based exclusive chemotherapy (EC) after they achieved a complete clinical response (CCR) to induction chemotherapy.

METHODS

One hundred forty-two who achieved a CCR after platin-based induction chemotherapy were treated exclusively with additional chemotherapy, and 98.6% were followed for a minimum of 3 years or until death. Thirty-five patients had >10 years of follow-up.

RESULTS

The survival rates at 1 year and 5 years were 95.8% and 61.2%, respectively. The main causes of death were metachronous second primary tumors (n = 27) and intercurrent disease (n = 21). Death related to EC was not encountered, and only 2 patients (1.4%) had grade 4 toxicity. In multivariate analysis, primary tumor arising outside the glottic larynx (P = .0001) and a Charlson comorbidity index >1 (P = .0001) were associated with a statistically significant reduction in survival. The 1-year and 5-year Kaplan-Meier local control estimates were 76.1% and 50.7%, respectively. Salvage treatment resulted in an observed final local control rate of 93% that varied from 97.2% in patients who had glottic cancer to 88.7% in patients who had tumor originating from other sites (P = .097). Combined chemotherapy with cisplatin and 5-fluorouracil (PF) allowed for the successful modulation of local therapy in 54.9% of patients.

CONCLUSIONS

For selected patients, EC may provide long-term, durable disease control. For patients who developed recurrent disease after EC, this approach did not diminish survival and maintained function in the majority of patients. Future work should be directed toward select markers of response to PF chemotherapy with which to identify those patients who are suited optimally for this approach.

Surgical therapy and olfactory function

This report provides an overview of the relationship between olfaction and surgery. Surgery can be considered as treatment for some olfactory dysfunctions. Moreover, olfactory dysfunction can be analysed as a complication of some surgical procedures. An impaired sense of smell is a common problem affecting approximately 65% of patients with chronic sinusitis. Much of the literature about the effect of surgery on the olfactory system is based on subjective reports of olfactory function, which do not accurately assess objective smell dysfunction. A small number of prospective studies have been published. All studies looking at the sense of smell have found overall post-operative improvement compared with pre-operative symptoms. The range of improvement compared with pre-operative scores ranged from 13 to 91%, with a median of 31%. Olfaction dysfunction can be a complication of various surgical procedures such as laryngectomy, septoplasty, rhinoplasty, ethmoidectomy, and some neurosurgical procedures.

[Analysis of the variables affecting patients' memorization and interpretation of information on thyroidectomy-related risks]

We prospectively analyzed patients' memorisation and interpretation of preoperative information on the risks of thyroidectomy. This study was conducted in an academic tertiary care referral center, based on an inception cohort of 280 patients who were consecutively informed of the risks of thyroidectomy (unilateral laryngeal immobility, bilateral laryngeal immobility, hypocalcemia, common surgical complications, and perioperative death) by the same surgeon during the period 2003-2006. Univariate analysis was used to identify factors affecting memorisation and interpretation of the information delivered. After being informed of the risks, 14.6% of patients declined surgery, and 5% decided to postpone the operation for a few months. Among the 215 patients who underwent thyroidectomy, 0.9% remembered all five risks, 17.2% three or four, 61.4% one or two, and 20.4% none. The number of risks remembered did not vary over time. Age, occupation, and the year of the analysis influenced memorisation. In the immediate post-operative period, 85.5% of the patients had a positive opinion and 45.1% a negative opinion of the preoperative information, and 35.3% simultaneously expressed positive and negative opinions. The number of preoperative visits and the interval between the final preoperative visit and surgery both affected the patients' interpretation of the information. Patient memorisation of information on surgical risks is poor, and this results in major stress for the patient. After receiving this information, a significant proportion of patients decide to forego surgery.

Final results following exclusive chemotherapy for selected patients with squamous cell carcinoma of the laryngopharynx

6039

Purpose: To determine the long-term oncologic outcomes for patients with squamous cell carcinoma (SCC) of the laryngopharynx treated with exclusive chemotherapy after complete clinical response to induction chemotherapy. Materials and Methods: After platin-based induction chemotherapy, selected patients with a complete clinical and histologic response were treated exclusively with additional chemotherapy and observed closely. The rates of overall survival, disease control, and organ preservation were calculated. Results: Survival at 1- and 5-years was 94.5% and 60.2%, respectively. Main causes of death were metachronous second primaries (27) and intercurrent disease (23) than local recurrence (10), distant metastasis, (9) and nodal recurrence (4). The 1-, 3- and 5- year Kaplan-Meier local control estimates were 73.5%, 53.3%, and 50.3%, respectively. No variable was associated with local recurrence using a multivariate analysis. Salvage treatment resulted in an observed final 85.6% local control rate and varied from 96% in patients with glottic cancer to 71% in patients with tumor originating from other locations. Overall, this treatment approach was well-tolerated: 30 patients (20%) experienced grade 3 toxicity; two patients (1.4%) had grade 4 toxicity events. Overall, chemotherapy allowed for successful modulation of local therapy in 66% of patients (96/146). Conclusions: For selected patients, exclusive chemotherapy does not significantly impact survival and maintains function in a majority of patients. Most remarkable, platin-based chemotherapy permitted us to modulate and to diminish the extent of local therapy. Future work should be directed to identify markers of response and resistance to identify which patients are best suited for this approach.
