Intranasal endoscopic prelacrimal recess approach to maxillary sinus

引用

Chinese Medical Journal 2013年第7期126卷 1276-1280页

作者： ZHOU Bing HAN De-min CUI Shun-jiu HUANG Qian WANG Cheng-shuo Department of Otolaryngology-Head and Neck Surgery Beijing Tongren Hospital Capital Medical University Key Laboratory of Otolaryngology Head and Neck Surgery (Capital Medical University) Ministry of Education Beijing 100730 China

Background The inferior turbinate （IT） and nasolacrimal duct （NLD） are often sacrificed while managing the diffuse lesion of maxillary sinus （MS）. We report a new approach to MS without ablation of NLD and IT. Methods This retrospective study enrolled 19 hospitalized patients （aged from 42 to 68 years） who underwent endoscopic sinus surgery between 2003 and 2008. Twelve patients had inverted papilloma （IP）, two had nasal polyps, two had Kubo＇s postoperative cyst of MS, one had recurrent bone cyst of maxilla, one had dentigerous cyst and one had bleeding of internal maxillary artery secondary to CaldwelI-Luc operation respectively. Two IP patients were excluded from this group since the follow-up time was less than 12 months. The NLD was dissected after removing the anterior bony portion of nasal lateral wall. The prelacrimal recess approach （PLRA） to MS was established when IT-NLD flap was raised medially. The flap was repositioned when MS lesion was removed. Results All the 17 patients had unilateral lesions. Ten MS IP patients were at the T3 Krouse stage. The follow-up ranged from 7 to 60 months. No recurrence was seen in 16 patients. Only one IP patient had a local recurrence in MS. All of them had no any complications. Conclusion The diffuse or severe diseases of MS may be the potential indications for PLRA.

Sinonasal Schwannoma in a Six-Year-Old: An Unusual Presentation

引用

Case Reports in Clinical Medicine 2016年第2期5卷 50-56页

Schwannomas commonly occur in the head and neck region and extremities, but nasal schwannoma is extremely rare. It accounts for less than 4% of benign solitary schwannomas of the head and neck region. Few cases and very few case series have been reported till date. We report the case of a six-year-old female who presented with mouth breathing of two years with persistent and progressive right nasal obstruction of three months. There was recurrent watery ipsilateral nasal discharge, but no epistaxis, no otologic or throat symptoms, no headaches, facial pain, proptosis or visual loss, no facial hypoesthesia, fever or weight loss. She also had right sided epiphora. She had used topical steroid and decongestant without improvement. Ten months prior to presentation, she had right dacrocystorhinostomy. Examination revealed mucosa mass completely filling the right nasal cavity with an ipsilateral deviation of nasal septum—it was painless with no contact bleeds. Nasal patency was clinically absent bilaterally. Computed tomogram revealed expansile isodense soft tissue mass in the right nasal cavity with heterogeneous enhancement on contrast administration which measured 2.5 cm by 3.7 cm by 5.2 cm. She had an intranasal excision of the tumour and histology revealed Antoni A and B patterns, which is diagnostic of schwannoma. She was fully relieved of symptoms after surgery. Conclusion: Solitary nasal schwannoma is rare especially in childhood. There are various causes of epiphora;definitive investigation of the cause in the index case was not established before dacrocystorhinostomy. Thorough nasal evaluation of epiphora or related ocular symptoms should be sought before definitive procedures.
