Bacteremia during tonsillectomy.

To determine the risk of bacteremia during tonsillectomy, we cultured blood specimens that were taken from 32 children during surgery and tonsillar swabs that were obtained just before excision, and compared the results with quantitative cultures of the excised tonsillar tissue. Twenty-five children had Haemophilus influenzae within the tonsillar tissue (density range, 10(3) to 10(8) colony-forming units per gram), and seven had Streptococcus pyogenes (density, 10(3) colony-forming units per gram in one case, 10(5) colony-forming units per gram in one case, and 10(6) colony-forming units per gram in five cases). Twelve perioperative blood cultures were positive; H influenzae was found nine times, and Micrococcus species was found one time, and alpha-hemolytic streptococci were found two times. Haemophilus influenzae was always present in the corresponding tonsillar specimens, although there was no apparent relationship between the density of colonization of the tonsillar tissue and a positive blood culture.

[Maxillary Aspergillus sinusitis. Comments apropos of 20 cases].

About a series of 20 aspergillus maxillary sinusitis, the correlation between this pathology and previous dental treatments is emphasized. In some cases such as sinusitis can occur without any dental pathology and/or in absence of foreign body on the X-rays. C.T. findings are the basis of the diagnosis. Surgical treatment, using endonasal micro surgery, has been performed in all cases.

[Mandibular fractures. Our patient enrollment during the past 2 years].

The method of patient referral; the patient's physical predisposition, the localization and the treatment undertaken for the different mandibular fractures seen by SOS Face over the past two years were analyzed. The 312 mandibular fractures were used to reevaluate the commonly accepted statistics concerning these parameters.

[Petrous surgical approaches in tumors of the cerebellopontine angle].

Three petrous incisions, performed by an ENT-neurosurgery team, can be used for the resection of tumours of the cerebellopontine angle: transpetrosal incisions (posterior translabyrinthine and transcochlear) which provide large access to the IAM and the posterior surface of the petrous bone, but they sacrifice hearing. The suprapetrosal incision (reserved for tumours in the meatus) and the mastoidoretrosigmoid incision (for tumours less than or equal to 20 mm) preserve the labyrinth in an attempt to preserve hearing. The principal objectives of surgical resection of tumours of the cerebellopontine angle (85% of which are acoustic neuromas) are total resection (to preserve the vital prognosis) and preservation of facial nerve function. Attempts to preserve hearing must be confined to cases selected by a complete clinical otological and audiometric examination.

[Pharyngolaryngeal fibroscopy under general anesthesia in children. Technique and indications in sleep apnea and hypopnea].

The frequency of obstructive sleep apnea syndromes in children is not negligible. The diagnosis is based on the parents' answers and on sleep recordings. Radiographs sometimes help defining the site of obstruction. However, except when there is a considerable, clinically obvious tonsillar hypertrophy (which is fortunately the most frequent case), the exact location of the obstruction may be difficult to assess. In fact, it is far less obvious and more often multiple than in adults, especially in cases of craniofacial malformation. A pharyngolaryngeal exploration technique with a flexible endoscope under general anesthesia (GA) has been developed in our department. With natural ventilation, when a GA is induced with halothane through a mask, muscular relaxation similar to that of natural sleep is obtained. A thin flexible endoscope is then inserted through the mask to observe the obstructive structures at the nasal, rhino/oropharyngeal or pharyngolaryngeal levels. During the past two years, 17 children were examined with this technique, which allows an extremely accurate diagnosis of the site of the obstruction. Four children had a craniofacial malformation. The examination evidenced 9 cases of adenotonsillar hypertrophy, 4 cases of dynamic laryngeal obstruction, 3 cases of basilingual obstruction and one case of circular collapse of the oropharynx. The evolution under treatment confirm the merits of this endoscopic examination technique for the etiological diagnosis of respiratory obstruction.

[Evaluation of the prognosis of facial paralysis after surgery of acoustic neurinoma by an early Hilger's test].

Surgery for acoustic neuroma is highly risky for the facial nerve. This is why we have tried to assess immediate postoperative facial impairment by performing Hilger's test within the first few hours. Further evolution of the facial function showed the predictive value of Hilger's test as regards facial recovery. Indeed, a difference greater than 2 mA as compared with the opposite side indicates a lack of facial recovery at the 3rd postoperative month. In addition, facial muscle testing performed within the first postoperative 72 hours makes the prognosis of facial function recovery possible. Lack of facial recovery at the 3rd postoperative month was observed for neuromas with a diameter exceeding 2 cm. Preoperative assessment of the risk of facial sequellae is fundamental and essentially depends on the size of the tumor and on the surgical approach. Intraoperative facial monitoring allows better ensuring the preservation of the VIIth cranial nerve and consequently improves postoperative function.
