Endoscopic septoplasty: Learning curve

AIMS

The aim of the current study was to report the learning curve for endoscopic septoplasty for a senior surgeon already trained in endonasal sinus surgery.

MATERIAL AND METHODS

From November 2011 to September 2012, 100 patients were prospectively included and grouped in 5 consecutive groups of 20 by date of surgery. The primary endpoint was operative time. Intra- and postoperative complications and functional assessment were also analyzed.

RESULTS

Operative time decreased with the surgeon's experience and became stable after 60 procedures. Operative time saving was about 10min per 20 procedures. Mean operative time was stable between groups 4 (21.1±9.6min) and 5 (19.2±8.2min). There was a 2% rate of conversion to conventional surgery for technical problems. The number of procedures free of accidental mucosal lesion increased and became stable after 40 procedures. There was a 4% rate of residual postoperative perforation. Nasal Obstruction and Septoplasty Effectiveness (NOSE) score improved postoperatively in each group (P<0.05).

CONCLUSION

After 60 endoscopic septoplasty procedures, a senior surgeon masters the surgical technique with satisfactory operative times, and a decreasing rate of intra- and postoperative complications.

Endoscopic vs. conventional septoplasty: A review of the literature

The aim of this review of literature was to compare conventional and endoscopic septoplasty in terms of operating time, functional efficacy and perioperative morbidity. A systematic review of the scientific literature was performed on the PubMed database, Google and Google Scholar, searching for randomized prospective trials comparing endoscopic and conventional septoplasty. The primary endpoint was operating time, and the secondary endpoints were intra- and postoperative complications, postoperative pain, hospital stay and functional result. Twenty-nine articles published between 1991 and 2012 compared conventional and endoscopic septoplasty, five of which were prospective randomized trials. Operating time was shorter with endoscopic surgery (P<0.001), with less mucosal damage (P<0.01); there was less synechia (P<0.01) and residual deformity (P<0.05); and postoperative pain was milder. Endoscopic septoplasty thus shortened surgery time and reduced perioperative complications, but the functional result was the same as with conventional septoplasty.

Endoscopic septoplasty: Tips and pearls

This article is designed to provide a step-by-step description of our endoscopic septoplasty technique and discuss its difficulties and technical tips. Endoscopic septoplasty comprises 10 steps: diagnostic endoscopy, subperichondral infiltration, left mucosal incision, dissection of the left subperichondral flap, cartilage incision (0.5 centimetre posterior to the mucosal incision), dissection of the right subperichondral flap, anterior cartilage resection, perpendicular plate dissection, dissection and resection of the maxillary crest, endoscopic revision, mucosal suture and Silastic stents. A satisfactory postoperative result was observed at 3 months in 97% of cases in this series. The main contraindication to endoscopic septoplasty is anterior columellar deviation of the nasal septum requiring a conventional procedure.

[Diagnosis and therapeutic pathways in head and neck cancers]

BACKGROUND

Cancers of uppers aero-digestives tracts represent, infrequency, the 5th cancer in the French population. Most of them (about 70%) are diagnosed at an advanced stage (stage III or IV) while they are associated with a poor prognosis (only 40% five year survival). The objective of our study was to analyze the care pathway of patients with cancers of uppers aero-digestives tracts in order to target efforts to improve the survival of these patients.

METHODS

It was a descriptive and retrospective study, on medical files, on the health care pathway of patients with cancers of uppers aero-digestives tracts cared in the Head and Neck surgery department of Val de Grâce in Paris and Percy in Clamart between January 2004 and December 2006. The patients were adults with squamous cell carcinoma of uppers aero-digestives tracts.

RESULTS

One hundred thirty-eight files of patients were analyzed. Fifty-five percent of patients were diagnosed at an advanced stage. On average patients have waited two months and twenty-one days before consulting a doctor for the first time. The time interval between the specialist consultation and the start of treatment was on average 7 weeks. The overall 5-year survival rate was 61%.

CONCLUSION

Squamous cell carcinoma of uppers aero-digestives tracts remains serious and has a poor diagnosis, even in a population with a high social-cultural level. The long time interval before the first consultation may be reduced by improving health education among the general practitioner (primary and secondary prevention), and by establishing health care public campaigns. This would allow earlier diagnosis, more conservative therapeutic opportunities and therefore a better prognosis.

Prevalence of and risk factors for obstructive syndrome apnea

INTRODUCTION

Obstructive Sleep Apnea Syndrome (OSAS) is becoming an important public health problem because of its frequency and adverse health consequences. The objective of this prospective study was to evaluate the prevalence of and risk factors for OSA in a cohort of subjects working for the french Army.

SUBJECTS AND METHODS

This prospective study was carried out on a sample of volunteers working for the French army. The subjects were recruited at their annual work visit between November 2008 and September 2009. Subjects were asked to complete 2 screening questionnaires (Epworth and Berlin) and were given a medical examination. Subjects suspected of having OSAS (based on high questionnaire scores) were monitored by nocturnal ventilatory polygraphy. OSAS was diagnosed if the subject was found to have an apnea/hypopnea index (AHI) greater than or equal to 5.

RESULTS

In this healthy, young and active population (n = 1054), 4.20% of subjects were diagnosed with OSA. Comparing our two groups of subjects (OSA and non-OSA), several statistically significant (p < .05) differences emerged that may be associated with OSA: the individuals with OSA were older by an average of 7 years, they presented with an average BMI greater than 4.5 kg/m2, an average abdominal girth greater than 12.2 cm and an average cervical circumference greater than 2.6 cm. In addition, they consumed more tobacco when they were smokers and were more likely to present with permanent nasal obstruction. They were also more likely to suffer from gastroesophageal reflux and present with skeletal class II. Finally, they presented with a longer average soft palate as determined by the Mallampati scoring system.

CONCLUSION

We found that the major risk factors for OSAS were age, BMI, abdominal girth and cervical circumference (linear correlations determined by bi-variate analysis).
