Maxillofacial neoplasms, though relatively rare, are potentially devastating tumors, that may require medical or surgical intervention. Among all the head and neck tumors, sino-nasal tumors make up 3%. Such tumors can be very vascular as well as extremely painful. Conventional analgesic treatment in a cascading manner usually proves to be inadequate and unsatisfactory. Interventional pain management offers promising long term pain relief. Sphenopalatine ganglion block can be offered to such patients for pain relief. Here we present a case report of a patient with painful large sino-nasal tumor for which spheno-palatine ganglion (SPG) block was performed with successful pain relief.

Background: Little is known about the cognitive profile of Hereditary Spastic Paraplegias (HSP), where most scientific attention has been given to motor features related to corticospinal tract degeneration. Objectives: We aimed to perform a broad characterization of the cognitive functions of patients with pure and complicated HSP as well as to determine the frequency of abnormal cognitive performances in the studied subtypes. Methods: A two-center cross-sectional case-control study was performed. All individuals underwent cognitive assessment through screening tests (Mini Mental State Examination-MEEM and Montreal Cognitive Assessment-MOCA) and tests to assess specific cognitive functions (Verbal fluency with phonological restriction-FAS; Verbal categorical fluency-FAS-cat and Rey's Verbal Auditory Learning Test-RAVLT). Results: Fifty four patients with genetically confirmed HSP diagnosis, 36 with spastic paraplegia type 4 (SPG4), 5 SPG11, 4 SPG5, 4 cerebrotendinous xanthomatosis (CTX), 3 SPG7 and 2 SPG3A, and 10 healthy, unrelated control subjects, with similar age, sex, and education participated in the study. SPG4 patients had worse performances in MOCA, FAS, FAS-cat, and RAVLT when compared to controls. Most SPG4 patients presented cognitive changes not compatible with dementia, performing poorly in memory, attention and executive functions. SPG5 patients scored lower in executive functions and memory, and SPG7 patients performed poorly on memory tasks. All evaluated cognitive functions were markedly altered in CTX and SPG11 patients. Conclusions: Cognitive abnormalities are frequent in HSP, being more severe in complicated forms. However, cognitive impairments of pure HSPs might impact patients' lives, decreasing families' socioeconomic status and contributing to the overall disease burden.
