摘要:

Sixty‐one patients with an osteoma of the frontal or ethmoid sinuses have been studied. The following indications for surgical removal of these osteomas are suggested: osteomas extending beyond the boundaries of the'frontal sinus, if enlarging, if localized in the region adjacent to the nasofrontal duct, if signs of chronic sinusitis are present, osteomas of the ethmoid sinuses, irrespective of their size and if patients with osteomas complain of headache and other causes of headache have been excluded. The operation of choice is the osteoplastic flap operatio

摘要:

There is now a joint UICC‐AJC classification for cervical lymph nodes based mainly on the size of the nodes. There is a recognized error in palpation, not only for detecting the presence of tumour but also its size. This study used an animal tumour model system to compare the ability of 6 independent observers of varying experience to detect and stage superficially transplanted growths. A preclinical medical student was as good as a Consultant ENT Surgeon in predicting the presence of tumour but the ability to stage tumours accurately was related to experience. Whilst the most experienced observers accurately estimated the size of tumours less than 2 cm, they were less accurate for larger (>2 cm) tumours which were constantly understaged. This phenomenon may have important clinical implications particularly related to current nodal staging criteri

摘要:

The purpose of this study was to compare the hearing results of performing stapedotomy using either a microdrill or a perforator. Two groups of patients, otherwise similar, were followed up for at least 2 years after the stapedotomy. It was possible to create 0.8 mm fenestra in 91.6% of our patients. There was no significant difference between the two groups in hearing results. The results showed a continuous improvement in the first 6 post‐operative months after which the hearing stabilized. In our hands, the microdrill has not proved to be more traumatic than the perforator to the inner ea

摘要:

A middle ear effusion has been shown, in KEMAR, to increase the height of the resonant peak of the external auditory canal by 6 dB SPL. It has also been shown that the hearing impairment due to otitis media with effusion is related to the volume of middle ear fluid. Therefore, it was hypothesized that measurement of the height of the resonant peak of the external auditory canal could be used as a method of assessing the magnitude of any hearing impairment due to otitis media with effusion. 182 ears from 182 children aged 3–12 (mean 6.3) years were studied. Pure‐tone audiometry and impedance tympanometry were performed, and the acoustics of the external auditory canal were measured using the Rastronics CCI‐10 frequency response analyser. The mean height of the resonant peak (17.9 dB SPL) of children with a type A tympanogram was significantly different from the mean value (23.6 dB SPL) of those with a type B tympanogram. There was a significant correlation between the height of the resonant peak and the speech frequency average of the pure‐tone thresholds. The sensitivity and specificity of using the height of the resonant peak to detect hearing impairments in different age groups were calculated and compared with the sensitivity and specificity of tympanometry. The test did not provide the same degree of sensitivity as tympanometry but was more specific. The additional advantages of the test are that it is quick, taking less than 1 min per ear, and is well tolerated by children in whom there was a 99% compliance. It is suggested that measurement of the height of the resonant peak of the external auditory canal holds potential as a quick and objective method of screening and monitoring the hearing impairment of children with otitis media with e

摘要:

The incidence and severity of respiratory symptoms after total laryngectomy and their influence on daily living were studied in 59 Iaryngectomized patients. Daily sputum production was the principal complaint of these patients (98%), followed by coughing (64%) and the need for frequent forced expectoration (more than 5 times a day) in order to clear the airway (57%). Frequent stoma cleaning (more than 5 times a day) was required by 37% of the patients. Significant correlation was found between respiratory symptoms, voice rehabilitation and several aspects of daily living, including fatigue, sleep problems, social contacts and psychological distress. These findings indicate that respiratory symptoms after total laryngectomy are both frequent and troublesome. The development of effective methods for minimizing and/ or preventing such respiratory problems would contribute significantly to improving the quality of life of laryngectomized patients.

摘要:

Results are presented of a preliminary study in which cAMP binding activity was measured in 34 specimens from a variety of head and neck sites. A wide range of cAMP binding protein levels was detected in all tissues assessed. There appeared to be a subgroup of parotid adenomas with increased cAMP binding activity. The biological significance of these proteins remains to be determined and their relationship to tumour growth in the head and neck is likely to be complex.

摘要:

Sonotubometry, as a technique for assessing Eustachian tube function, does not rely on an intact tympanic membrane. This device has been used to study 25 patients having myringoplasty who all had preoperative testing and post‐operative testing at 4 months. The overall success rate for grafting was 76%. In those who had normal preoperative tubal function the success rate was 86%, as opposed to 67% in those whose preoperative tubal function was poor. This difference was not statistically significant. In all those patients where poor preoperative function ended with successful grafting, post‐operative tubal function reverted to normal. Other factors also taken into account, such as the patient's age, size of the perforation and the operative difficulty, had no bearing on the outcome of surg

摘要:

The nasal airway resistance of 15 patients with unilateral chronic otitis media and 15 controls was measured by anterior active rhinomanometry. Airway resistance was measured on each side before and after decongestion to differentiate resistance due to structural abnormality from that due to mucosal swelling. The nasal resistance was significantly greater (P<0.01) on the side of the affected ear in patients with unilateral chronic otitis media before decongestion, but following decongestion the difference was not significant. Nasal obstruction is a significant determinant in unilateral chronic otitis media and although septal displacement may be the underlying cause, the major component of the obstruction appears to be due to an associated mucosal oedema.

摘要:

An epidemiological case‐control study was conducted to investigate occupational risk factors in cancers of the upper respiratory and digestive tract. Cases were men with squamous cell carcinoma of the oropharynx (667), hypopharynx (348), glottis (246), supraglottis (219), epilarynx (204), and 4 subsites of the oral cavity (787). Controls were healthy patients or patients with cancer of another site or another histological type (147 men). Past occupational exposures of cases and controls were compared. The analysis was performed independently for each site of cancer, controlling for age, amount and type of alcohol and tobacco consumption, and state of dentition. Results showed that cancer of the supraglottis was associated with exposure to oil and grease (odds ratio = 2.4; 95% confidence interval 1.0–5.8), and with exposure to cement (odds ratio = 4.2; 95% confidence interval = 1.1–16.4). Cancer of the glottis was also associated with exposure to dye (odds ratio = 6.4; 95% confidence interval = 0.7–56.6). Exposure to flour occurred more frequently among controls than among patients with pharyngeal or oral cancer. This might reflect an association between this occupational exposure and some particular types of cancer included in the contro
