Endoscopic endonasal techniques have recently become the method of choice in dealing with cerebrospinal fluid leak involving the anterior cranial fossa. However, most surgeons prefer an intracranial approach when leaks involve the middle cranial fossa. This case report illustrates the possibilities of using endoscopic techniques for cerebrospinal fluid leaks involving the middle fossa.

Objective To objectively compare the nasal decongestion potency of lidocaine/phenylephrine when delivered with a nasal nebulizer and a nasal spray before a rigid nasoendoscopic examination. Study Design Open-label randomized controlled trial. Setting Multicenter study. Methods This prospective clinical trial involved 106 participants with untreated chronic rhinitis. Fifty-three participants had 400 μL of lidocaine/phenylephrine administered into the right nostril with a nasal nebulizer, while the remaining 53 participants had 400 μL administered with a nasal spray. The control was the left nostril. Nasal resistance at 150-Pa fixed pressure was evaluated with an active anterior rhinomanometry at 5, 10, 15, and 30 minutes postintervention. Pain score was assessed subjectively by applying pressure to the inferior turbinate 30 minutes after intervention. Results There was an overall reduction in nasal resistance of the right nostril when lidocaine/phenylephrine was administered with the nasal nebulizer in comparison with the nasal spray. However, a statistically significant difference in nasal resistance was seen only at 5 minutes ( P = .047), 15 minutes ( P = .016), and 30 minutes ( P = .036). The examining endoscopist further supported the degree of nasal decongestion via subjective assessment of the nasal cavity ( P = .001). Pain scores obtained after the intervention showed a significant decrease in pain threshold when the nasal nebulizer was used instead of the nasal spray ( P = .040). Conclusions This study suggests that the delivery of lidocaine/phenylephrine to the nasal cavity by the nasal nebulizer provides better decongestive and analgesic potency as compared with the delivery by nasal sprays.

Effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery: a randomised, controlled study

Ng BHK, Tang IP, Narayanan P, Raman R, Carrau RL

J Laryngol Otol, 2019 Dec;133(12):1059-1063.

BACKGROUND: Nasal lavage with mupirocin has the potential to reduce sinonasal morbidity in endoscopic endonasal approaches for skull base surgery.
OBJECTIVE: To evaluate the effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery.
METHODS: A pilot randomised, controlled trial was conducted on 20 adult patients who had undergone endoscopic endonasal approaches for skull base lesions. These patients were randomly assigned to cohorts using nasal lavages with mupirocin or without mupirocin. Patients were assessed in the out-patient clinic, one week and one month after surgery, using the 22-item Sino-Nasal Outcome Test questionnaire and nasal endoscopy.
RESULTS: Patients in the mupirocin nasal lavage group had lower nasal endoscopy scores post-operatively, and a statistically significant larger difference in nasal endoscopy scores at one month compared to one week. The mupirocin nasal lavage group also showed better Sino-Nasal Outcome Test scores at one month compared to the group without mupirocin.
CONCLUSION: Nasal lavage with mupirocin seems to yield better outcomes regarding patients' symptoms and endoscopic findings.

Fulltext Primary oesophageal Ki (CD30)-positive ALK+ anaplastic large cell lymphoma of T-cell phenotype

Primary oesophageal lymphoma is a very rare entity, with fewer than 30 reported cases worldwide. It represents an important cause of dysphagia. Most of the oesophageal lymphomas are diffuse large B-cell type, with only one reported case of anaplastic large cell lymphoma (ALCL) of T-cell phenotype. Primary oesophageal lymphomas that are not associated with an immunocompromised state tend to affect elderly patients. We describe the first case of primary oesophageal Ki (CD30)-positive ALK+ALCL of T-cell phenotype in a 34-year-old immunocompetent woman, who presented with a two-year history of dysphagia. She was treated with chemotherapy and endoscopic oesophageal dilations and stenting, resulting in complete remission of the lymphoma and resolution of the dysphagia. She then underwent autologous peripheral blood haematopoietic stem cell transplantation and remained disease-free two years after the diagnosis.

Endonasal endoscopic repair of anterior skull-base fistulas: the Kuala Lumpur experience

The purpose of this retrospective study is to determine the pattern of cerebrospinal fluid (CSF) rhinorrhoea presenting to our tertiary referral centre in Kuala Lumpur and to assess the clinical outcomes of endonasal endoscopic surgery for repair of anterior skull base fistulas. Sixteen patients were treated between 1998 and 2004. The aetiology of the condition was spontaneous in seven and acquired in nine patients. In the acquired category, three patients had accidental trauma and this was iatrogenic in six patients (five post pituitary surgery), with one post endoscopic sinus surgery (ESS). Imaging included computed tomography (CT) scan and magnetic resonance imaging (MRI). Endoscopic repair is less suited for defects in the frontal sinuses with prominent lateral extension and defects greater than 1.5 cm in diameter involving the skull base. Fascia lata, middle turbinate mucosa, nasal perichondrium and ear fat ('bath plug') were the preferred repair materials in the anterior skull base, whereas fascia lata, cartilage and abdominal fat obliteration was preferentially used in the sphenoid leak repair. Intrathecal sodium flourescein helped to confirm the site of CSF fistula in 81.3 per cent of the patients. Ninety per cent of the patients who underwent 'bath plug' repair were successful. The overall success rate for a primary endoscopic procedure was 87.5 per cent, although in two cases a second endoscopic procedure was required for closure. In the majority of cases endoscopic repair was successful, and this avoids many of the complications associated with craniotomy, particularly in a young population. Therefore it is our preferred option, but an alternative procedure should be utilized should this prove necessary.
