Locoregional Flaps In Pediatric Anterior Skull Base Surgery Operative This flap provides excellent coverage for lateral skull base defects but can also be used for anterior skull base defects extending as far medially as the clivus. operative technique similar to the tpf flap, make a hemicoronoal or y shaped incision in the temple extending into a preauricular skin crease and extend it down to the temporalis fascia. Management of skull base defects involves the separation of the cranial cavity from the nasal cavity in order to prevent cerebrospinal fluid leak, pneumocephalus, and intracranial infection. the size and location of the defect as well as donor tissue available will determine the type of reconstruction. reconstruction options include free tissue grafts, locoregional flaps, and microvascular.
Locoregional Flaps In Pediatric Anterior Skull Base Surgery Operative Al: reconstruction of the cranial base following endonasal skull base surgery: regional tissue flaps. operative techniques in oto laryngology (march 2010, volume 21, issue 1, pages 83 90). figure 4 anterior skull base repair. (a) large dural defect at the anterior skull base. (b) transposition of the pericranial flap closing the defect. The tpf flap provides a thin layer of well vascularized tissue that is excellent for a variety of defects given its length and pliability. 8 it can be used for anterior and lateral skull base defects, orbital roof, and middle fossa defects, as well a sling for orbital floor reconstruction. 9 the flap can be transposed via a transpterygoid corridor in order to reconstruct anterior skull base. The size and location of the defect as well as donor tissue available will determine the type of reconstruction. reconstruction options include free tissue grafts, locoregional flaps, and microvascular free flaps. in children, the size of potential flaps must be considered as well as the length of the pedicle, as often these differ in children. Although it did not reach to the statistical difference, yano et al 30 reported that using free flaps in pediatrics tended to have higher postoperative complication rate than using locoregional flaps compared with that of adult, thus advocated locoregional flaps as the flaps of first choice for skull base reconstruction if they are large enough.

For small and localized defects, for example, localized region i and region ii defects, of either the anterior or middle skull base, locoregional flaps, such as pericranial flaps and temporalis muscle flaps, are the flaps of first choice, even for pediatric patients (figs. 1 and and2). 2). locoregional flaps are usually raised by plastic. However, given its distance from the defect and significant tunneling required, the flap has limited use over the anterior skull base. 12 free flaps free flaps have also been described for large.
