    Middle-Ear Resonance Frequency and Eustachian Tube Function in Players of Wind Instruments
    (2021) Ozer, Fulya; Ozer, Cem; Erbek, Seyra; Ozluoglu, Levent N.; 0000-0002-8453-6069; 0000-0002-6641-5300; 0000-0001-5381-6861; 34412053; AAJ-2445-2021; ABH-1785-2020; ABC-1809-2020
    Introduction: The effect of the continuous forced expiration action of players of wind instruments to produce sound, on the eustachian tube functions and the middle-ear resonance frequency (RF), has not been investigated in the literature to date. The aim of this study is to evaluate eustachian tube functions and the middle-ear RF of players of wind instruments. Methods: In this prospective case-control clinical study, a study group of 28 players of wind instruments in the orchestra (28 participants, 56 ears) and a control group of 34 volunteers (34 participants, 68 ears) were included. The eustachian function of wind instrument players in a symphony orchestra was measured using an automatic eustachian tube function test in acoustic tympanometry and the RF of the middle ear was determined in multifrequency tympanometry. Results: There was a statistically significant difference among the musicians, especially in players of woodwind instruments, in terms of dysfunction of the eustachian tubes (p = 0.048). In the musicians, the pre- and postperformance RF mean values for all ears were 925 and 1,020 Hz, respectively, and these were significantly different (p = 0.004). Conclusion: This is the first study to uses multifrequency tympanometry to examine the middle-ear RF and eustachian tube function of wind instrument musicians in an orchestra. Eustachian tube dysfunction was found to be more prominent and a higher RF of the middle ear was seen after a performance, especially in players of wood wind instruments. However, the effect of these on the professional performance of players of wind instruments should be investigated in future work.

    Upright positioning-related reverse nystagmus in posterior canal benign paroxysmal positional vertigo and its effect on prognosis
    (2020) Jafarov, Sabuhi; Hizal, Evren; Bahcecitapar, Melike; Ozluoglu, Levent N.; 0000-0002-2150-0237; 0000-0002-9699-6783; 0000-0002-7302-4199; 32597824; AAI-8020-2021; A-5853-2018; AAI-8044-2021
    BACKGROUND: Positional nystagmus elicited by the Dix-Hallpike maneuver often reverses its direction as the patient is re-seated from the provoking head hanging position. The incidence of reverse nystagmus and its association with prognosis in posterior canal benign paroxysmal positional vertigo (pcBPPV) is not clear. OBJECTIVE: To determine the incidence of upright positioning-related reverse nystagmus and its association with the success of canalith repositioning (Epley) maneuver (CRM) treatment in pcBPPV. METHODS: The records of patients that had been tested with video-nystagmography in a tertiary care center, between October 2016 and March 2019, were reviewed. Data were obtained from detailed analysis of video recordings of 321 patients with typical pcBPPV. RESULTS: Reverse nystagmus was determined in 85% of the patients with pcBPPV. The number of CRMs required for treatment was lower in patients with reverse nystagmus (1.32 +/- 0.68) compared to patients without reverse nystagmus (1.81 +/- 0.98) (p < 0.001). There was not a statistically significant relationship between reverse nystagmus and recurrence (p = 0.623). CONCLUSIONS: The absence of reverse nystagmus on upright positioning during the Dix-Hallpike test predicts poor success for the CRM, as repetitive repositioning maneuvers might be required to achieve successful treatment in pcBPPV.

    Transient Velopharyngeal Insufficiency After Calcified Stylohyoid Ligament Resection
    (2020) Cam, Osman Halit; Kocdor, Pelin; Ozluoglu, Levent N.; 0000-0001-9253-1412; 0000-0002-2150-0237; 32371704; AAP-1533-2020; AAD-7236-2021; AAI-8020-2021
    Elongation of the stylohyoid process or calcification of the stylohyoid ligament is known as the Eagle syndrome. Mostly, it is seen incidentally on imaging or with extreme suspicion and usually patients are asymptomatic. Surgery is the preferred method in symptomatic patients. Transcervical or transoral methods may be preferred as surgical route. A 28-year-old female patient who had formerly underwent tonsillectomy presented with throat and ear pain. A neck computed tomography was performed, and the patient was diagnosed as Eagle Syndrome. Surgery was recommended. Patient developed transient velopharyngeal insufficiency on postoperative day 4. Ventilation exercise and follow-up was recommended. Complaints of the patient decreased on the 15th day. It should be kept in mind that stylohyoid ligament may be calcified in young age group and middle age group patients with dysphagia or odynophagia, and differential diagnosis should be performed. Another issue is the condition of velofaringeal insufficiency which may occur due to the damage of the pharynx muscles by deep dissection during surgery.
