Context:Many reconstructive techniques have been proposed to prevent postoperative cerebrospinal fluid (CSF) leakage after trans-sphenoidal pituitary surgery. However, no total agreement has been reached to the best technique.Aim:Assessment of the efficacy of sellar repair with autologous muscle and composite septal cartilage grafts for treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain.Study Design:This is a retrospective case series study, level IV evidence.Materials and Methods: Twenty three patients were involved in this study. Seventeen patients had intraoperative CSF leakage and were treated immediately by our technique. Six patients had postoperative CSF rhinorrhea and had delayed treatment with our technique after failure of conservative measures and external lumbar CSF drainage for more than three days. The technique involved intradural placement of autologous muscle graft supplemented with extradural composite septal cartilage graft, composed of a piece of the posterior cartilaginous septum with its covering mucoperichondrium on one side only to fit into the sellar defect as a double layer button.Results:CSF leak was of grade 1 in 6 patients (26.1%), grade 2 in 10 patients (43.5%) and grade 3 in 7 patients (30.4%). None of the patients in our study had postoperative CSF leak after the use of our technique during the follow up period (mean 24 ± 10.47 standard deviation months). None of the patients developed treatment-related complications. All the patients had well developed mucosal covering of the sellar defect after two months.Conclusion:Our technique of sellar repair by using autologous muscle and composite septal cartilage grafts is effective in treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain even in the high-output CSF leaks.

Objectives Nasal dermoid cysts are rare congenital lesions of ectodermal and mesodermal origin. Treatment of these cysts entails complete surgical excision, and several surgical incisions have been advocated. We present our experience utilizing an external rhinoplasty approach in seven children with nasal dermoid cysts and fistulae. Methods A prospective study of 7 cases of nasal dermoid cysts and sinuses, diagnosed clinically and radiologically, were successfully treated by an external rhinoplasty approach in two teaching hospitals during the period of Apr 2011 to Nov 2013. Post operatively, an average follow-up of 12 months was observed by clinical examination, and the outcomes were documented and analysed. Results Seven children, 5 girls (71%) and 2 boys (29%), with ages ranging from 1.5 years to 16 years, who had nasal dermoid cysts and/or sinuses were successfully excised via an external rhinoplasty approach. The clinical presentation included midline facial swelling in five patients, a midline sinus in one patient and a dorsal midline nasal pit in one patient. No accessory tracts were found in these seven cases. Complete excision was achieved in 6 patients. There was one recurrence after 6 months with a successful complete resection with revision external rhinoplasty. All patients were followed up for an average of one year post operatively. Conclusion The external rhinoplasty approach is an effective surgical approach in treating paediatric nasal dermoid cysts and sinuses with a very low incidence of recurrence.

EnAbstract Background Nasolabial cysts are rare lesions present in the soft tissues beneath the ala nasi. Excision of the cyst through the sublabial incision is the most well-known treatment modality, with a low recurrence rate. Objective In this study, we discuss, through a literature review, the diagnosis, differential diagnosis, and a modified combined endoscopic and sublabial surgical technique for the treatment of this disorder. Patients and methods Ten patients with a confirmed diagnosis of nasolabial cysts underwent combined endoscopic and sublabial enucleation of the cysts, and were followed up with a clinical examination and endoscopic assessment. Results No recurrence was recorded during a follow-up period ranging from 3 to 12 months. Conclusion Nasolabial cysts can be enucleated with the use of a nasal endoscope to ensure complete excision.
