A modified longitudinal incision via transoral sublabial approach for removal of the nasal vestibular cyst: a clinical observation.

OBJECTIVE: The aim of this study was to investigate the clinical effect of the removal of nasal vestibular cysts through a modified longitudinal incision via a transoral sublabial approach. METHOD: In 28 cases, a nasal vestibular cyst was removed through a modified longitudinal incision via a transoral sublabial approach. A visual analogue scale score was used to evaluate the numbness of the nasal alar and upper lip. Post-operative complications were recorded. Medical photographs were used for assessment. RESULTS: For all patients, incisions reached clinical primary healing one week after surgery. All patients were free of post-operative haematoma, infection, oronasal fistula and malformation. In the first week and the first month after surgery, numbness of the nasal alar and upper lip was recorded in few cases. The patients were followed up for 2-57 months without recurrence. CONCLUSION: Removal of nasal vestibular cysts via a transoral sublabial approach with a modified longitudinal incision is a minimally invasive and simple surgical method with few complications and a quick recovery.

[Application of image navigation assisted nasal endoscopic surgery in optic nerve decompression].

Objective:To explore the application and to evaluate the advantage of image navigation assisted nasal endoscopic surgery in optic nerve decompression. Method:Sixty patients accepted the image navigation assisted nasal endoscopic surgery therapy in optic nerve decompression were included in this retrospective study and followed up for about six months to four years. Result:The visual acuity was improved in 16 cases with visual acuity above light. One case is 10 cm index, two cases are 40 cm index, one case is 70 cm index, the visual acuity of rest 12 cases was between 0.04 and 0.30, two of them were missing from the field of view, the effective rate was 100%. The 44 cases without light sensation before operation, postoperative visual acuity was improved in 11 cases, four of which were light sensation and visible figure. Visual acuity of seven cases was between 0.03 and 0.08, one of them was missing from the field of view, the effective rate was 25%. No complications occurred. Conclusion:With the help of the image navigation, it is convenient and accurate to locate the anatomical marker sites such as orbital apex, optic canal and fracture site, internal carotid artery and so on, as a result, the accuracy and the success rate of the surgery were greatly improved.

Transoral and endoscope-assisted transoral approaches to resecting benign tumours of the parapharyngeal space located in the medial portion of the carotid sheaths and extending toward the skull base: our experience.

OBJECTIVE: Various surgical approaches have been described to remove tumours in the parapharyngeal space. This study investigated the feasibility of a transoral approach in the surgical management of parapharyngeal space benign tumours located in the medial portion of the carotid sheaths and extending toward the skull base. METHODS: Thirty-two patients were selected and underwent a transoral or an endoscope-assisted transoral approach in the surgical management of parapharyngeal space benign tumours located in the medial portion of the carotid sheaths. Medical photographs were used. RESULTS: All patients underwent complete resection of their lesions via a transoral or endoscope-assisted transoral approach. None of the patients demonstrated residual or recurrent neoplasms, either clinically or radiographically, during their follow up. CONCLUSION: Based on our studies, we assert that transoral and endoscope-assisted transoral approaches are suitable in managing parapharyngeal space benign tumours located in the medial portion of the carotid sheaths and extending toward the skull base.

[Wegner's granulomatosis of hypolarynx in a patient with laryngemphraxis: case report and review of literature].

Summary A patient suffered from progressive dyspnea and even laryngeal obstruction visited our department in May, 2017 and received emergency tracheotomy for assistance in breathing. There was no dysphagia, sore throat, fever, cough, hemoptysis and hematuresis. The pathological signs including facies dolorosa, three depressions sign, perforation of nasal septum. The laboratory examination showed that there were hematuresis and albuminuria. The urine bilirubin levels were elevated, antineutrophil cytoplasmic antibody (ANCA) was positive and antiproteinase 3 antibody was elevated. The electronic laryngoscope revealed the swelling of infraglottic region and laryngeal CT showed the subglottic area occupation and stenosis. The pulmonary CT showed the irregular mass shadow in lower lobe of right lung which was considered benign pathological changes. Finally, the diagnosis was subglottic Wegner's granulomatosis and result in laryngeal obstruction and need the first aid in clinic.

[Hypopharyngeal angiofibroma: a case report].

Swallowing obstruction, gradually increase, with a sore throat, no fever, no haemoptysis, no dyspnea, routine tests: blood routine, biochemical examination, blood coagulation routine, electrocardiogram, chest X-ray, did not show abnormalities.

[A new method to evaluate the eustachian tube function].

OBJECTIVE: To study the practicality of a new method to evaluate eustachian tube function. METHOD: We acquired the tympanogram of 30 normal persons (60 cases) by means of classical tympanometry, Toynbee test and valsalva maneuvre respectively, the peak point of each tympanogram was P1, P2 and P3 corresponding P1 -P2 > 10 daPa or Pmax-Pmin > 15 daPa was accepted as normal. RESULT: 70% cases were accepted normal, whose peak point shifted obviously. CONCLUSION: The method is a simple, objective and practical one; If the peak point shifts obviously, the function of ET is normal; On the contrary, if the function of ET may be abnormal, other tests should be performed.

[The evaluation of eustachian tube function in patients suffered from SOM with C type curve].

OBJECTIVE: To explore eustachian tube (ET) function in patients suffered from SOM with C type curve. METHOD: To test the tympanogram following toynbee test and valsalva manoeuvre respectively. The shift of peak point was quantified and the results were compared with normal subjects. RESULT: ET dysfunction was found in 52.38% of the patients, it was observed in 30% of the normal subjects (P < 0.05). CONCLUSION: ET dysfunction is one of the causes of SOM with C type curve, but not the only cause.

[The role of tracheotomy in saving the patients suffered from lung blast injury].

OBJECTIVE: To explore the role of tracheotomy in saving the patients suffered from lung blast injury. METHOD: To analyse the pathological change of lung blast injury and to make a retrospective analysis for clinical data of 8 cases. RESULT: Three severe injuries accompanying asphyxia, SaO2 < 75%, were tracheotomized and sucked hemorrhagic frothy sputum in trachea at once, and they were saved successfully. The other 5 cases, SaO2 > or = 90%, were not tracheotomized. CONCLUSION: During saving the lung blast injury, tracheotomy has an important role in sucking hemorrhagic frothy sputum in trachea and keeping the respiratory tract unobstructed.

The micro-determination of serum gamma-glutamyl transferase.

The method of serum gamma-glutamyl transferase colorimeter assay was modified by changing the wave length from 420 nm to 400 nm, the incubated temperature from 37 degrees C to 50 degrees C, the sample amount from 30 microliters to 6 microliters. The modified method was proved to be more sensitive, with CV of intra-group being 2.06% and accuracy 97.4%. The method is suitable for clinical application with small-amount blood samples collected from earlobe or finger tip.
