METHODS: Sixteen patients were recruited for voice analysis during pre-operative, within two weeks and at least three months post-operatively. Subjective questionnaire was used to assess perception of voice changes.
RESULTS: There were no statistically significant changes in the acoustic parameters of patients with nasal polyposis. In patients with CRS without polyps, there was a statistically significant increase in fundamental frequency (F0) in nasal sound during early follow up. The changes in soft phonation index (SPI) values between the two groups were statistically significant during early follow-ups. Only patients with nasal polyposis perceived a subjective change in their voice post-operatively.
CONCLUSIONS: Clinicians should inform all patients, especially voice professionals about the possible effects of endoscopic sinus surgeries on their voice quality.
METHODS: A single case report of a female patient with the diagnosis of REAH, detailing her presenting symptoms, clinical findings, management and follow up.
RESULTS: Histopathological assessment of the excised nasopharyngeal polyp was consistent with a diagnosis of REAH with a discussion on the disease and its current literature reviews.
CONCLUSION: The incidence of REAH within the nasopharynx remain rare with only few cases described in literature, especially in females.
CASE REPORT: A case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. The first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent man who complained of trigeminal neuralgia type pain. It was difficult to differentiate between infection and tumour despite the utilization of computed tomography scans and magnetic resonance imaging.
CONCLUSION: These cases illustrate the need for a high index of suspicion; in addition to endoscopic confirmation and histopathology to establish precise diagnosis and early intervention.
Methods: There were 20 healthy participants with normal ears, and all gave an informed consent. After an otoscopy, a baseline pure tone audiogram (PTA) was conducted. If the PTA of the participant was normal, aqueous cream was applied with a syringe via an 18 G cannula, from the tympanic membrane up to the isthmus which corresponds to the bony ear canal. A second PTA was conducted, and subsequently the cream was removed via suction under microscope guidance. The procedure was then repeated with the cream applied from the isthmus to the aperture of the external ear canal using the same cannula followed by a PTA and removal of cream under microscope.
Results: The mean threshold difference of occlusion at both portions of the ear canal were compared and analyzed. The mean threshold difference of hearing loss upon occlusion at the cartilaginous EAC was 37.5 to 48 dB. The mean threshold difference of hearing loss upon occlusion at the bony EAC was less, with a range of 21 to 24.95dB. There was a statistical difference (p<0.05) in the hearing loss between the blockage of the cartilaginous canal versus the blockage of the bony canal with a maximum difference at 2kHz.
Conclusion: Cartilaginous block of the external ear canal causes more hearing loss than block of the bony ear canal. This correlates with the concept and properties of sound waves, resonance and impedance.
CASE REPORT: A 60-year-old man was presented to the Otolaryngology Department with progressive dyspnoea and dysphagia to solids for over a period of 1 week. Direct laryngoscopy revealed a tumour at the laryngeal aspect of the epiglottis, which prolapsed into the laryngeal inlet each time the patient inspired. This resulted in an inspiratory stridor despite adequate glottic opening and normal mobility of the vocal cords.
CONCLUSION: Therefore, in cases where a ball-valve lesion causes intermittent life-threatening airway obstruction, BSCC of the larynx, though rare, must be considered as a differential diagnosis.
