The Correlation of Normal Adult Mastoid Pneumatization Volume and the History of Otitis Media in Childhood / 听力学及言语疾病杂志

Objective To explore the volume size of mastoid pneumatization in normal adults and the relation‐ship with a history of recurrent otitis media in childhood .Methods A total of in 40 adults (80 ears) ,based on with or without otitis media in childhood ,were divided into the study group (n= 20) and the control group (n=20) . The volume sizes of mastoid pneumatization were measured by temporal bone CT scanning of three-dimensional re‐construction ,and the relationship with the history of childhood ear infections was studied .Results The average vol‐ume of pneumatization in all 80 temporal bones was 10 .4 ± 1 .8 ml .The average volume of pneumatization in sub‐jects without otitis media history (48 ears) and subjects with a history of otitis media (32 ears) were 9 .7 ± 2 .2 ml and 6 .3 ± 1 .7 ml ,respectively .The difference was statistically significant (P0 .05) .Conclusion The volumes of mastoid pneumatization in normal ears have a wide range .The subjects with a history of recurrent otitis media in childhood may be the cause of the volume decrease of mastoid pneumatization in adulthood .

Nasal-cardiac reflex initiated by nasal packing (three cases report and literature review) / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To sum up the diagnosis and treatment experience of the nasal-cardiac reflex initiated by postoperative nasal packing.@*METHOD@#The clinical data of 3 cases with nasal-cardiac reflex initiated by postoperative nasal packing were analyzed retrospectively.@*RESULT@#In the period of postoperative nasal packing, 3 patients had abruptly drops in heart rate and blood pressure associated with symptoms of autonomic dysfunction such as flustered, chest tightness, tachypnea, body sweating et al. There are no positive signs of pathological significance in the cardiovascular and respiratory system. The reflex had spontaneously to be offset with oxygen, comfort touch therapy, pull out the stuffing, no other special treatment for all cases.@*CONCLUSION@#The key of the diagnosis for nasal-cardiac reflex is a drop in mean arterial blood pressure (MABP) and the heart rate (HR) more than 20% above the baseline values. The cause of nasal-cardiac reflex initiated by postoperative nasal packing is long-term mechanical pressure on the nasal mucosa and mental factors. Comfort touch therapy and pull out the nasal packing material is effective method to terminate the reflex and the prognosis is good. Correct understanding of the characteristics of the reflex and preventing the occurrence of its adverse consequences have important clinical significance.

Clinical analysis on the cervical vertigo after operation of middle ear / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To sum up the diagnosis and treatment experience of the cervical vertigo after operation of middle ear.@*METHOD@#The clinical data on 4 patients with cervical vertigo after operation of middle ear were analyzed retrospectively.@*RESULT@#Four patients had vertigo closely related to rotation of the head and neck after general anesthesia sober,and had swelling and pain of the neck- occipital and lateral neck. Neck rotation induced test of four cases were positive. Four cases treated with oral difenidol tablets and intravenous Salvia and energy mixture, and the vertigo was cured during 5-7 days.@*CONCLUSION@#The key of the diagnosis for the cervical vertigo is pain of the neck and vertigo closely related with rotation of the head and neck. The cause of the cervical vertigo after operation of middle ear is excessive deviation of the head position during operation. Anti-vertigo and vasodilators treatment for the cervical vertigo after operation of middle ear are effective and the prognosis is good. Identification with vertigo caused by the damage of the labyrinthine has important clinical significance.
