Objective:To study the influence of endoscopic sinus surgery(ESS)on nasal airway resistance(NAR) of intranasal contact point headaches.Method:The NAR and nasalairflow sensation were measured with anterior rhinomanometry in 20 patients(40sides) before and after the ESS.Result:A telephone follow-up six months after operation,16(85%)cases were cured,3(15%)were improved and 1(5%)had no response and the effective rate was 95%. NAR decreased significantly after the operation. The change ratesin NAR before and after the decongestion were there was a significant difference(P<0.05).Conclusion:The improvement of nasal functions by ESS is due to thealteration of the anatomic structure of the nasal cavity and the amelioration of mucosal edema. The rhinomanometry can be used as a useful clinical tool in determining nasal patency.

Objective To investigate the morphological changes in wound margin during the repair of traumatic tympanic membrane perforation patched by gelatin sponge with the aid of an endoscope in evaluating the prognosis. Methods Twenty-three female patients with traumatic tympanic membrane perforation within 6 hours were patched repaired with therapeutic gelatin sponge patches. Changes in the wound margin of traumatic tympanic membrane and the morphology of healed tympanic membrane were observed with endoscope. Results Among the 23 cases, infection occurred in 2 cases, and 5 were lost for follow-up. In the other 16 cases, the healing time in 11 cases was between 6 days and 20 days. On the first day after treatment, granulation and exudation increased around the wound margin. Hyperaemia was observed in both tympanic annulus and the handle of malleus. On the second day, granulation tissue increased further, and epithelization was observed on the third to sixth day. Hyperplasia of epithelial layer was accompanied by the formation of fibrosis of traumatic tympanic membrane. The initial healed tympanic membrane was thicker than normal and then thinned gradually in the following 3 days to 1 week. The threshold of pure tone audiometry in speech frequency was improved by 25?10dB. In 3 cases of these 16 patients, the healing time was 26-74 days with no hyperplasia of granulation tissue. In the other 2 cases of these 16 patients, the wound margin was surrounded by crust and failed to heal in 3 weeks. Conclusion Granulation hyplasia and increase in exudation can improve the repair of traumatic tympanic membrane by patching of a therapeutic gelatin sponge and shorten the healing time. When the wound margin was surrounded by crust hinders the repair of traumatic tympanic membrane.

With individualized treatment, 110 cases had fully recovered, 63 cases excellence and 31 cases utility,and the efficiency rate was 96.23%. Conclusion:Pharyngeal paraesthesia can be caused by several factors. Thorough examination and comprehensive analysis should be applied to those incurable patient who has been treated for a long time. Short course of treatment and irrational drug use are the main causes of short term recurrence and unsatisfactory curative effect.

Objective To study the causes and theoretical basis for good bone healing ability of magnetic Porous Ca3 (PO4) 2 ( MPTCP). Methods Seven MPTCP specimens with size of 2 cm × 1 cm × 0.5 cm were placed in the material physical system for detecting 42 times and the mean detection value was used to measure the MPTCP curve. The attachment 16451B of impedance spectrometer HP RLC was employed to measure dielectric spectroscopy and dielectric spectroscopy of MPTCP. Four-wire method was used to measure the impedance of MPTCP. Results The magnetic intensity changed rapidly when magnetic field was in a range of-10,000-10,000 Oe. The peak of dielectric spectroscopy and impedance of magnetic bioceramics was in the range of 103-104 Hz. When the external electromagnetic wave of frequency was ≤ 1 000 Hz, electrical impedance of MPTCP was large;while when the electromagnetic wave frequency was≥1 000 Hz, the impedance was relatively small and stable. Conclusion The environmental magnetic fields may change the magnetic and electric behavior of MPTCP and promote the biological healing, which may be the cause for the good bone healing ability of MPTCP.
