Erkennung und Vermeidung von Schwierigkeiten bei der Tränenwegschirurgie

Zusammenfassung

Die operative Versorgung der intra- und postsakkalen Tränenwegstenose gehört zu den besonders erfolgversprechenden Eingriffen des Fachgebiets. Um das Potenzial der endonasalen Dakryozystorhinostomie ganz auszuschöpfen, um Fehler in der Auswahl der Patienten, in der technischen Durchführung, aber auch in der Kommunikation mit den Kollegen der Ophthalmologie zu vermeiden, müssen einige diagnostische und differenzialindikatorische Aspekte berücksichtigt werden. Geordnet nach dem klinischen Ablauf der Patientenversorgung werden diese hier vor dem Hintergrund der aktuellen Literatur dargestellt.

Oncological Outcomes Following Transoral CO 2 Laser Microsurgery for T1 Glottic Cancer

Abstract

The objective of this study is to analyze oncological outcomes for treatment of Tis and T1 glottic squamous cell carcinoma after transoral laser microsurgery. This study is retrospective analysis of previously untreated, suspected lesion of glottis, staged cT1a and cT1b squamous cell carcinoma in a tertiary care hospital and 53 patients were included in the study. End points for analysis were local control, overall and disease specific survival rates. The local control, ultimate local control with laser alone, 3-year overall survival, 3-year disease specific survival and organ preservation rates were 86.7, 90.5, 92.4, 98.1 and 98.1% respectively. The involvement of anterior commissure did not show any significant impact on local control or survival. TLM is safe and effective treatment of early glottis cancer, associated with less morbidity and a high percentage of local control, survival and organ preservation rates.

Audiological Evaluation in Hypothyroid Patients and Effect of Thyroxine Replacement Therapy

Abstract

To do the audiological evaluation of patients with hypothyroidism and to assess status of hearing after thyroxin replacement therapy (TRT). Two groups were included: a hypothyroidism group (HG, n = 50), and a control group (CG, n = 50). Parameters studied: anominesic data, duration of hypothyroidism, comorbidities, cochleovestibular symptoms, biochemical and hormonal exams (TSH, FT4 and FT3), pure tone audiometry, impendence audiometry and BERA as where required. Mean age of the patients in HG was 26.5 ± 10.4 years. Male/Female ratio was 2.39. All HG patients had altered TSH values and 8% had diminished T4 values. Cochleovestibular symptoms were more common in hypothyroid patients (48%) than control (20%) p value. Pure Tone Audiometric threshold was found higher in 34% of cases. Sensorineural hearing loss was most common (76.46%) compared to conductive and mixed hearing loss. BERA showed significant prolonged absolute peak latency of wave III, inter peak latency (IPL) of wave I–III and reduced amplitude of wave Ia and Va. After thyroxine replacement therapy there was statistically significant improvement in hearing threshold in 46.42% ears (p  < 0.05), (if ≥ 5 dB hearing improvement consider as significant). The significant improvement was also found in BERA, in amplitude of wave Va. Site of involvement was at several levels, middle ear, cochlear or retro-cochlear. HG patients had more cochleovestibular symptoms, higher audiometric thresholds, increase in latency of wave III, IPL of I–III and reduced Ia and Va amplitude in the BERA. After TRT improvement in hearing threshold and BERA was found.

Early Speech Perception Test Outcome in Children with Severe Sensorineural Hearing Loss with Unilateral Cochlear Implants Alone versus Bimodal Stimulation

Abstract

Bilateral stimulation of the auditory system has clear advantages over unilateral hearing. Hearing-impaired children are, therefore, generally fitted with hearing aids in both ears so that they can have the benefits of binaural hearing. Children who use acochlear implant in one ear and no acoustic stimulation in the opposite ear are at a definite disadvantage. This study was undertaken to determine the advantages of bimodal stimulation in pediatric population especially in terms of speech recognition. This study comprised of 30 children between 3 and 6 years of age with profound bilateral sensorineural hearing loss with cochlear implant in one ear and fitted with digital hearing aid in non-implanted ear. Speech recognition performance was compared in unilateral cochlear implant only and with bimodal hearing stimulation in the same set of children. A statistically significant difference was found between speech reception scores in children with a unilateral cochlear implant only and those with a cochlear implant in one ear and a hearing aid in the non implanted ear in quiet surroundings. It is suggested that the use of bimodal fitting be considered as an effective management method to obtain the advantage of binaural hearing in children who undergo unilateral cochlear implantation.
