Epithelial migration of the postmyringoplasty tympanic membrane.

OBJECTIVE: To determine whether the postmyringoplasty tympanic membrane (TM) behaves in a similar way compared with a healthy nonoperated eardrum by calculating and comparing the epithelial migration rate and pattern. STUDY DESIGN: Prospective, nonrandomized case-control study. Each subject who has undergone a myringoplasty and with healthy contralateral TM as control is included in this study. SETTING: Otolaryngology outpatient clinic. PATIENTS: A total of 23 subjects with 46 ears have been selected from otolaryngology outpatient clinic of the University Malaya Medical Center after excluding two subjects from this study. The study was conducted from June 2003 to September 2004. INTERVENTION: All the selected subjects' ears were examined under a microscope. Methylene blue ink dot was applied to the epithelium of the TM at the immediate vicinity of the umbo; then, weekly follow-up was performed until the migratory pattern and the rate of epithelial migration was noted. MAIN OUTCOME MEASURE: Direction and rate of epithelial migration in both study and control group were measured and compared. RESULTS: Epithelial migration did occur in postgrafted TM, from the umbo region toward the ear canal wall in a lateral radiating manner. Most of the patients (19 of 23 patients [82.6%]) showed nearly similar migratory pattern (same direction) in both the control and the study ear. None of the 46 ears showed any evidence of epithelial migration in the anteroinferior direction of TM. The rate of migration was slower in the beginning, especially near the umbo region (almost no movement at the first 1 or 2 weeks after ink dot application). For both groups, the rate of migration increased when approaching the periphery or annulus region. There was not much difference in the mean daily migratory rate between the control and the study ear (93.4 microm/d and 91.7 microm/d, respectively). The mean migratory rate was highest in subtotal perforation (97.2 microm/d) and lowest in small perforations (< 20%; 83.6 microm/d). CONCLUSION: There was no difference in epithelial migration rate and pattern between the postmyringoplasty TM and the healthy TM.

Role of impacted cerumen in hearing loss.

We performed a study to determine if cerumen in the ear canal causes significant hearing loss and to ascertain if there is any correlation between the amount of cerumen and the degree of hearing loss. Our study was conducted on 109 ears in 80 patients. The results indicated that impacted cerumen does cause a significant degree of conductive hearing loss. We found no significant correlation between the length of the cerumen plug and the severity of hearing loss. Nor did we find any significant correlation between the presence of impacted cerumen and variables such as age, sex, ethnicity, or affected side.

Nasopharyngeal carcinoma and nasal allergy: any correlation?

Although it has been observed that nasal allergy is rarely seen in patients who have nasopharyngeal carcinoma, to our knowledge, no actual study of such a lack of association has been previously reported. To fill this void, we conducted a pilot study to investigate any such inverse relationship. We conducted skin-prick allergen tests on 22 patients with newly diagnosed but not-yet-treated nasopharyngeal carcinoma. Combining these test results with findings on the history and clinical examination, we concluded that only one of the 22 cancer patients (4.5%) had allergic rhinitis. Our study also confirmed the validity of using findings on the history, clinical examination, and skin-prick testing as a reliable means of diagnosing allergic rhinitis.

Tracheostomy in patients with cervical rib: a note of caution.

Cervical rib is a congenital phenomenon that usually occurs in association with upper-limb neurovascular symptoms. The presence of a cervical rib displaces the great vessels that cross the thoracic outlet superiorly and proceed into the neck. We report an unusual case of iatrogenic hemorrhage during a tracheostomy in a patient whose right subclavian artery had been displaced by a cervical rib. Our aim is to alert surgeons to the hidden risks of this phenomenon.

Spontaneous sublingual hematoma as a complication of severe hypertension: first report of a case.

We describe what we believe is the first reported case of a sublingual hematoma secondary to severe hypertension. The patient, a 77-year-old woman, experienced a spontaneous hematoma of the floor of the mouth, tongue, and sublingual space that eventually caused an airway obstruction. We performed an emergency tracheostomy under local anesthesia and then evacuated the hematoma through an incision along the floor of the mouth. The patient recovered uneventfully.

Evaluation of tracheal diameter after surgical tracheostomy.

PURPOSE: The aim of this study was to evaluate the narrowing of the trachea in head and neck surgical patients who had undergone elective tracheostomy. MATERIALS AND METHODS: This is a prospective study. Twenty-five patients were included in this study. All these patients had a preoperative elective tracheotomy, preceding major head and neck surgery for head and neck malignancies. An x-ray of the lateral soft tissue neck was taken after a minimum of 6 weeks after the dissimulation of tracheotomy tube. Diameter of the trachea above the stoma (around 2 cm below the cricoid ring that can be clearly seen in lateral x-ray corresponding to the second tracheal ring) was taken as controls. Data were entered into a computer database and statistically analyzed using SPSS for Windows (version 12.0; SPSS, Chicago, Ill). In addition to descriptive statistics for all patients, inferential statistics were used to compare the 2 tracheal diameters across all patients and within the subgroups of men and women. Associations between outcome and other variables were evaluated statistically using an chi 2 test for the categorical data. Other parametric and nonparametric statistical tests were used when appropriate. Criterion for statistical significance was set at P < .05 (Student t test and 2-tailed test). RESULTS: From this study, 92% (23/25) patients developed narrowing of trachea, all less than 50%. Very early decanulation of tracheotomy shows low or no narrowing at all. There is gradual narrowing in patients in whom dissimulations were performed after 14 days. Ethnicities of Indian decent (13/25) predominate in this study population. Male patients in this study have shorter decanulation period compared with female. CONCLUSIONS: Elective surgical tracheotomy is a relatively safe procedure resulting in minimum asymptomatic tracheal stenosis.
