Association between secretory otitis media and laryngopharygeal reflux in adults.

Background: The relationship between Secretory Otitis Media (SOM) and Laryngopharygeal Reflux (LPR) hasn't been well investigated in adult.

Purpose: To study the involvement of LPR- in adult SOM.

Methods: We analyzed 60 adult SOM patients who were admitted to Department of Otolaryngology and Head and Neck Surgery, the First Affiliated Hospital of Anhui Medical University, China from January 2022 to October 2022.

Combination of a negative pressure suction device and endoscope can accurately locate the bleeding site of refractory epistaxis.

Background: Selective endoscopic coagulation of a nasal bleeding vessel is an effective means of treating epistaxis. Precisely locating the bleeding site(s) is critical.

Objective: To investigate the utility of combining a negative pressure suction device and endoscope in locating bleeding sites of refractory epistaxis.

Association between SP-A rs1965708 gene polymorphism and allergic rhinitis risk in Chinese population.

Background: Pulmonary surfactant protein A (SP-A) in the respiratory tract plays an important role in host. In the present, we assessed the association between SP-A gene polymorphism and allergic rhinitis.

Methods: Using a case-control design, we compared the genotype frequencies of SP-A rs1965708 between allergic rhinitis patients and healthy control group.

[Pedicle flap of nasal septum-basis nasi and temporal muscucofascial flap to repair nasoseptal perforation].

Objective: To explore curative effect with pedicle flap of nasal septum-basis nasi and temporal muscucofascial flap to repair nasal septal perforation.

Method: Dissecting mucoperichondrium and mucoperioseptum around the perforation and taking dowm and out xia-ward to the floor of nasal cavity to make a inferior extremity pedicle flap. Then,the flap was tumbled and sutured onto raw surface of contralateral side through perforation.

Evaluation of the noise generated by otological electrical drills and suction during cadaver surgery.

Conclusion: Noise levels sufficient to cause sensorineural hearing loss can be measured when electrical drills and suction are used during otological surgery, particularly if a running burr touches the endosteal membrane of the otic capsule. Our noise measurements confirm the theory that 'soft surgery' should be employed during otological surgery, with focus on reduction of noise exposure.

Objective: To investigate noise levels generated by otological electrical drills and suction.

Evaluation of the usefulness of a silicone tube connected to a microphone in monitoring noise levels induced by drilling during mastoidectomy and cochleostomy.

Conclusion: The use of a silicone tube and a microphone enables peroperative noise recordings in cadavers and should be safe to apply in vivo. Our preliminary data indicate that noise levels during inner ear surgery reach levels that can cause noise-induced hearing loss. Our method is easily performed and enables future uncomplicated and safe noise recordings and we suggest future application in vivo to expand knowledge regarding peroperative noise levels.
