Application of CO2 laser and self-made laryngeal dilator in the treatment of the laryngeal stenosis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the treatment effect of CO2 laser and self-made laryngeal dilator on the laryngeal stenosis.@*METHOD@#Twenty-five patients with laryngeal stenosis were treated with CO2 laser and self-made laryngeal dilator. The laryngeal cavity scar was resected as much as possible by using CO2 laser and the laryngeal cavity was exposed by placing laryngeal dilator under general anesthesia.@*RESULT@#The 24 cases of all were successfully decanulated 1 to 12 months after operation and could breathe freely. One case had second operation and was successfully decanulated 9 months after operation. The follow-up for 1 to 2 years showed all cases speaking well and 3 cases recurrence.@*CONCLUSION@#The method for treating laryngeal stenosis using CO2 laser and self-mande laryngeal dilator is effective, fewer complication, less invasive, and faster recovery. The laryngeal dilator is made simply and conveniently.

Utilization of functional neck dissection for treatment of recurrent branchial cleft anomalies / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the utilization of functional neck dissection for treatment of recurrent branchial cleft anomalies.@*METHOD@#Fifteen patients with recurrent branchial cleft anomalies (fistula and cyst) undergoing functional neck dissection were retrospectively analyzed.@*RESULT@#Complications included 2 incisions secondary healing, 1 postoperative choking persisting for 1 months and 1 Horner's syndrome. There was no recurrence after a follow up from 2 months to 6 years,except 2 cases were lost to follow-up.@*CONCLUSION@#Functional neck dissection is an effective and safe surgical management for recurrent second and third branchial cleft anomalies(fistula and cyst).

Investigation of the surgical approach for resecting infratemporal fossa pterygomaxillary fossa-parapharyngeal space tumor / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the optimal surgical approach for resecting infratemporal fossa-pterygomaxillary fossa-parapharyngeal space tumor. The aim of this study is to enhance therapeutic effect and reduce complications and sequelae.@*METHOD@#Sixty-six patients with infratemporal fossa-pterygomaxillary fossa-parapharyngeal space tumor were analyzed retrospectively from 1998-2004, including complains, symptoms, physical signs; histodiagnosis, image examinations and surgical approaches.@*RESULT@#No recurrence was found in fifty benign tumor cases after 2 to 5 years, while in 16 cases with malignant tumor, four patients died in one year, 8 cases died in 2 to 4 years, and only 4 patients' survival time exceeded 4 years.@*CONCLUSION@#Extended maxillectomy is suitable for resecting primary carcinoma of maxillary sinus invading pterygomaxillary fossa, infratemporal fossa and /or parapharyngeal space tumor. also midface degloving approach is suitable for nasal primary cavity, nasal sinuses, nasopharynx and/or pterygomaxillary fossa tumor and localized malignant tumor. Trans-cervical combining mandibular split swing approach is suitable for parapharyngeal space tumor invading pterygomaxillary fossa and/or infratemporal fossa tumor. Trans-cervical jaw combining mandibulotomy is suitable for resecting parapharyngeal space, infratemporal fossa tumor for invading lateral skull base and pterygomaxillary fossa tumor.
