Analysis of relation between the development of study and literatures about benign positional paroxysmal vertigo published international and domestic / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder that causes vertigo. Study of BPPV has dramatically rapid progress in recent years. We analyze the BPPV growth@*METHOD@#We searched the international data quantity year by year in database of PubMed, ScienceDirect and WILEY before 2014 respectively, then we searched the domestic data quantity year by year in database of CNKI, VIP and Wanfang Data before 2015 by selecting "Benign paroxysmal positional vertigo" as the keywords. Then we carried out regression analysis with the gathered results in above databases to determine data growth regularity and main factors that affect future development of BPPV. Also, we analyzes published BPPV papers in domestic and international journals.@*RESULT@#PubMed database contains 808 literatures, ScienceDirect contains 177 database and WILEY contains 46 literatures, All together we collected 1 038 international articles. CNKI contains 440 literatures, VIP contains 580 literatures and WanFang data contains 449 literatures. All together we collected 1 469 domestic literatures. It shows the rising trend of the literature accumulation amount of BPPV. The scattered point diagram of BPPV shows an exponential growing trend, which was growing slowly in the early time but rapidly in recent years.@*CONCLUSION@#It shows that the development of BPPV has three stages from international arical: exploration period (before 1985), breakthrough period (1986-1998). The deepening stage (after 1998), Chinese literature also has three stages from domestic BPPV precess. Blank period (before the year of 1982), the enlightenment period (1982-2004), the deepening stage (after the year of 2004). In the pregress of BPPV, many outsantding sccholars played an important role in domestic scitifction of researching, which has produced a certain influence in the worldwide.

A new classification of extensions of the sphenoid sinus of Chinese adult by CT / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To examine various pneumatized extensions of the sphenoid sinus of Chinese people.@*METHOD@#The sphenoid sinus and its surrounding structures were examined from 100 computed tomography images of the sinus. The type of the sphenoid sinus was classified according to the various extensions of the sinus.@*RESULT@#The type of the sphenoid sinus was classified into the following 6 basic types based on the direction of pneumatization: sphenoid body, lateral, clival, lesser wing, anterior, and combined.@*CONCLUSION@#The variations in the extensions of pneumatization of the sphenoid sinus may facilitate entry into areas bordering the sphenoid sinus.

Clinical analysis of 14 cases with nasal respiratory enithelial adenomatoid hamartom / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To describe and analyze the clinical features of nasal respiratory epithelial adenomatoid hamartom and improve the levels of diagnosis and treatment.@*METHOD@#Fourteen cases of nasal respiratory epithelial adenomatoid hamartom confirmed by pathology were collected and analyzed.@*RESULT@#In 14 cases, primary complaint of Hyposmia(or Anosmia)and nasal obstruction were occured in 13 and 11 cases respectively. Four cases had past history of endoscopic sinus surgery because of the diagnosis of nasal polyps. Polypoid neoplasms could be seen in the bilateral olfactory clefts. Sinus CT showed soft tissue shadows in bilateral nasal cavity and mucous membrane thickening in different sinus. Endoscopic sinus surgery were utilized to eliminate focus in all cases. All cases weren t recurred after 2-20 months' following-up visitings.@*CONCLUSION@#Nasal respiratory epithelial adenomatoid hamartom is so rare that clinical and pathological doctors have limited knowledge of it. It has its own characteristics from the clinical symptoms, signs to sinus CT although they are nonspecific. So we should improve the understanding about it to avoid misdiagnosis or missed diagnosis.

The necessity of post-maneuver postural restriction in treating benign paroxysmal positional vertigo / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the necessity of postural restrictions after repositioning maneuvers in posterior canal benign paroxysmal positional vertigo (BPPV).@*METHOD@#Sixty-eight consecutive patients diagnosed of posterior canal BPPV with a positive Dix-Hallpike test. Thirty-two patients were instructed to follow postural restrictions after repositioning maneuvers, and 36 patients did not receive any postural restriction after treatment. All the patients were reevaluated at 1 week and 3 months later respectively.@*RESULT@#There was no statistical difference in number of maneuvers needed to resolve symptoms between two groups.@*CONCLUSION@#Epley maneuver is effective to treat patients with posterior canal BPPV, and postural restrictions does not improved the efficacy. Above all, we do not recommend any postural restrictions to patients with posterior canal BPPV.
